If the collision system in this video no longer works for you, you might need to enable "collision compatibility mode" in Game Options -> Main Options -> General. GameMaker has changed over the years! Alternatively, I have released a new 5 minute video that covers all of these basics and is up to date with 2022+ standards: ruclips.net/video/ywgkXbHYJNE/видео.html
I cant find collision compatibility any where. Tried looking up global setting but I couldn't find anything. Can you tell me where this setting is located?

I know you already got a lot of praise for this tutorial but here: Your tutorial made coding fun for me (I've been trying to learn for a month) Took me about 1.5h to get this done and it's incredible, I'm looking forward to the rest of the series :D I will coment on as many videos as I remember so the algarythm hopefully pushes this amazing tutorial to more people looking to code
Programming tip: Avoid abreviations like hsp, vsp, grv, walksp. These can confuse you or others in the future, It's better to spend some extra time to write out a longer name for it, for example: horizonatal_speed, vertical_speed, gravity, walk_speed Now you will know exactly what every variable is for, so you won't have to guess what it is for. (it may not seam like an issue now, but over time when you have a lot of them, you'll have a hard time remembering what every single variable means, and what the exact name for a variable you need is, when you have ones more like the ones above, you can just write out what the variable is for rather than a code name for it)
If u want multiple ways of controlling the item use this block: key_left = keyboard_check(ord("A")) or keyboard_check(vk_left); key_right = keyboard_check(ord("D")) or keyboard_check(vk_right); key_jump = keyboard_check_pressed(vk_space) or keyboard_check(ord("W")) or keyboard_check(vk_up); this lets the player control the enttiy in many ways.
This video is delicious! Downloaded GMS2 after realising Unity was overkill for my needs - creating my first 2d platformer for fun. Glad I've chosen your channel as my learning tool right from the beginning!
This is really cool, thank you for making this series, but I have some questions. For starting from scratch, did you choose blank game or platformer? After that did you choose, GML Code or GML Visual?

I remember 3 years ago I went to learn GameMaker Studio, and Shaun's platformer tutorial was there for me to learn. Now I can produce a platformer on the spot without any references. I'm delighted to see that you're producing a tutorial for the people getting into GM:S 2. Thanks Shaun.
Too Long; Didn't Study Can relate, mate, he gets an 8/8. (sorry couldn't resist) Seriously though, Shaun helped me start programming, which led me to get into advanced programming(OO) The amount of stuff I learnt on this channel is alot. Just checking in to help these people with their errors.
I'm gonna subscribe I'm new to gamemaker studio 2. My friend and I want to make very awesome games for fun and maybe for a bit if cash but mostly for fun I can't wait for more content like this :)
Hi, I have a problem with loading my game... it takes me 30 seconds. Do you maybe know what is wrong? The computer is very fast. Thank you for great tutorials.
Anybody who wants to add A = left and D = right (like the WASD controls) just do this: key_left = keyboard_check(ord("A")); key_right = keyboard_check(ord("D"));
Thank you! I always thought arrow controls were a little wonky. (Maybe I could add both? Who knows what the preference of the person that plays my game will be?)
man... I meet gamemaker at my 14, and I didn't understand a sh*t because in that time there wasn't RUclips tutorials, and I didn't understand english pretty well you are so lucky lol
My brother wants to make games, so i gave him a chance. after one hour i saw him writing this in the computer: if (scrolling_through_twitter = true) { dad_visible = false; } else { dad_visible = true; } 💀💀💀💀
This video made coding fun for me. So much so that I made it wall jump! //Wall Jump if (place_meeting(x+hsp,y,oWall)) && (key_jump) { vsp = -7; } Thanks!!! You are an awesome teacher :D
for anyone looking to copy this, you might also add momentum away from the wall hsp = -sign(hsp) * 2; and if you're doing it after the collision (which makes sense) hsp will be 0, so save sign(hsp) in the collision and set the walljump's place meeting to (x+hSignVariable,y,oWall)

@@captaincharlie1044 I found a better way since then //check for a wall in the direction you're pointing if (place_meeting(x+move,y,oWall)) && (key_jump) { vsp = -7; hsp = -3 * move; //move away from the direction you're pointing }
@@hole1274 alright, sorry for keeping this going, but the wall jump works! however, i dont want the player to be able to just keep on wall jumping up the same wall over and over. i want them to kind of bounce away from the wall naturally after one walljump. would you know how to do this? if its easier(and if you have discord) my discord username is EdgeGod27 #3004
[SOLUTION] If your player is "floating" and stays in the air too long, then you need to raise your grv variable. At 29:03, Shaun changes the value from 0.1 to 0.3. He does it really fast and might be hard to catch. Good luck with your game!
This was AWESOME! I had a couple glitches as I went. My mistakes helped me learn stuff: 1. If you're seeing boxes to drag instead of a place to type in the Create tab as shown in the video, right click and select Switch to GML. 2. I had a typo in one of my variables in the Create tab. I had walkvp instead of walksp! Also, WALKSP is not the same as walksp - capitalization DOES count. 3. I had semicolons at the end of my if and while statements. Don't put semicolons there. 4. I put a semicolon instead of a comma in one of the x,y+1,o_wall statements. Excellent, nay, PERFECT video for a first timer.
I can't get past this part for some reason, my player just automatically goes left all the time and i cant bring it to the right Edit: fixed it, i wrote x = x * hsp; which was why it wasn't working
If you want to add sprinting to the game you just need to put: key_sprint = keyboard_check(vk_shift); to the key section and add: if(key_sprint) { hsp *= 1.75; } in front of: x = x + hsp;
//Get Player Input key_left = keyboard_check(vk_left); key_right = keyboard_check(vk_right); key_jump = keyboard_check_pressed(vk_space); //Calculate Movement var move = key_right - key_left; hsp = move * walksp; vsp = vsp + grv; //horizontal Collision if (place_meeting(x+hsp,y,oWall)) { while (!place_meeting(x+sign(hsp),y,oWall)) { x = x + sign(hsp); } hsp = 0; } x = x + hsp; //vertical Collision if (place_meeting(x,y+vsp,oWall)) { while (!place_meeting(x,y+sign(vsp),oWall)) { y = y + sign(vsp); } vsp = 0; } y = y + vsp; game wont run keep getting errors, i was at 29:28 in video what is wrong with my code?

[[ SOLUTION ]] Lots of guys having a problem where the player just falls into the ground and become incapable of moving, i had the same problem and found some unanswred comments asking for help.. i latter found that the IF statment on the vertical collision part had "y+sign(vsp)" written rather than 'y+vsp", wich is the correct way... im proud as a begginer to have discovered the logical problem by myself, although i shoudn't had comited it in the first place hahaa
Jesse Damon if you set the collision to check on y+sign(vsp), it will be true everytime the collision mask is exactly one pixel above the ground, and will send you to the same place again and again and again
Although my vision for what I want to make isn't a platformer, this was an awesome intro and I'm a little upset I'm so early to the series because I want to spend a day just working through these tutorials! It's like when you start watching a show during it's initial air vs when the series is complete, the wait is awful lol.
Just a tip for any future game developers, when you get stuck like this, duplicate your project then start experimenting. or have other smaller projects to work on.
I don't often write comments on videos, but I feel obligated to thank you for an amazing set of tutorials with good start. I'm excited to be able to code my first game, as I've only worked as an artist in video-games.
Thanks you, this is great. I was struggling with other tutorials to understand the code, but I understood most of this and feel I'm making progress for the first time with all this making games stuff. I'm looking forward to continuing.
I was having a problem where my player would just fall through the ground I fixed it by : 1. Going to the player sprite in the workspace tab and expanding collision mask (left hand side) 2. setting mode to "manual" 3. looking at the sprite preview window and clicking and dragging a black box over the entire sprite I think the reason I got this error is that I changed the origin of the object ( in the video somewhere around 2:03) to top left instead of center but i'm not sure.
Hey man/miss I've been coding for a bit and working with stuff like this and yet I thought my code was F***ed. Bouta start again and then I checked the comments. You saved me. Hats of to good sir.
After doing this I still have the green box fall through the ground, it'll still stop at the sides of the walls, but it still falls through. Need help :(
a lot of games work even better at higher frame rates than your monitor can push out. Dont believe me? if you're playing counter-strike with a locked frame-rate try taking it off. This isn't something that's discussed all that often because of the power needed to push a game beyond 200 fps. playing a game at 80fps or whatever just means screen tearing
Any idea why I'm getting an error in the Step event? key_left is underlined with message GM2016 - Instance variable 'key_left' declared outside of Create event, declare with 'var' or move to Create event. Everything is setup exactly as demonstrated in the video. Similar errors for key_right and key_jump. I'm also getting a naming convention error for move, it says it should be "_move".
they're just suggestions for keeping things tidy, these errors werent made at the time this video came out so they werent considered. as long as your game still launches they aren't anything to stress over (i know this is a very late reply and you probably figured it out but still lol)
im new to GameMaker, I've had a decent amount of coding experience back in high school but I have long since forgotten. You are a god send. you are a wonderful teacher, and great to listen to. thank you for all you do and please, keep doing it!
This is my first ever comment on RUclips I think. But I just wanted to say thank you for taking the time to make these videos. It is extremely helpful for a beginner.
I'am trying to get the horizontal colison to work but i just simply does not, i copied word from word os the video code, but it's not working, tried checking the colision of the wall and its fine, can someone help me. here is the code: if place_meeting(x + hsp,y,oWall) {
while (!place_meeting(x + sign(hsp),y,oWall)) { x = x + sign(hsp) } hsp = 0 }
Wow! I've watched my first 8 minutes and i've gotten more done than any other tutorial! You can sure explain stuff and i'm looking forward to more and more content from you!
I've been writing platform games since 85' while in high school using 6502 on an Apple IIe, what I've learned in this life is that the most important thing an artist can do (that is what we all are) is to master the rudiments, before we can construct the fantastic. I really enjoyed getting this man's perspective on "elegant logic" for good object control in a platform game construct. You "experts" are encouraged to just go over this step by step and you may be surprised at a perspective you didn't have on some very elemental, but critical components of game making. Thanks again Shaun.
It's possible to experience a game freeze using this method of movement/collision if you character falls onto the corner of a block at certain angles. From what I remember, this is because the collision wasn't set up for diagonal collision, so to avoid the issue, add this below your horizontal and vertical collision //Diagonal Collision if (place_meeting(x+hsp,y+vsp,oWall)) { while (!place_meeting(x+sign(hsp),y+sign(vsp),oWall)) { x += sign(hsp); y += sign(vsp);
@@susniynarezchik I haven't had any issues using acceleration and this code so far, as all the code is for is to stop you from getting frozen in a while loop when you land on a corner at a near perfect 45 degree angle, which is pretty much the only time the code seems to fire
@@timtam4596 Yooooo i didnt think you would adress my comment that fast! As i said, your code works perfectly fine without need of any momentum implementation, but in my case it didnt work out. So, for example, i tried saving data of hsp to some momentum_saver variable right before the jump (i had set different accel/decel for it), but right before the variables data gets saved, it changes to 0. First of all, i tried saving hsp data at a different place, but I couldnt get it accurate enough. For now, i basically did a simple pre-hmove check, and turned hsp to 0 if future collision detected (also i needed that bc my character goes way too fast for game to control), and before that i save my momentum data. it turned out smth like that: //Horisontal collision if (place_meeting(x+hsp, y, oPlatform) ){ while (!place_meeting(x+sign(hsp),y,oPlatform)){ x = x + sign(hsp); momentum_save = hsp; } hsp = 0; } //momentum save (post collision check) if (place_meeting(x - hsp, y - vsp, oPlatform) and state_c == "running"){ momentum_saver = hsp; } //Pre horizontal move check if (place_meeting(x+hsp,y,oSpikes) or place_meeting(x+hsp,y,oPlatform)) { hsp = 0; } x = x + hsp; Yeah, as u get it, i am new to gm, and i very appreciate your help to us, newbies. I guess i might find more elegant solution later, but it is what it is right now. (And yeah lol, sorry for any potential grammar mistakes i made here, since english isnt my first language.) Anyways, wishing you best of luck!
I think there is a reference problem, make sure that oplayer its written the same on the objects and in the code. Is it really Oplayer with capital O and low p or its like oWall, only the W capital?
Literally watched this 8 times and cant get my player to go, i know a lot of gml and gm2 and the code doesnt work Took me awhile code works you ser this, im wrong sorry, i had 2 dk_lefts, silly meeeee
I’m immediately running into an issue, I’ve copied down exactly the coding you used and yet my character will not move when I press the left and right buttons
I know this is three months old but I found the solution to this for anyone who was wondering like I was. What I did was in the map placed the sprites into the room. You need to place the OBJECTS into the room. The sprites are just pictures they aren't the objects with the coding. Replace the sprites with objects and this should work!
Contact Parkour This is a very bad idea, but I don’t want to bother with tech support so try to use drag and drop mode and use the tutorials from the official website of the devs. Basically there are blocks that do the typing for you. Like a puzzle. Good luck. Plus it might be an update that broke it. I’ll try another time
The collision code works great but there is one problem with it. Since it doesn't check the space in-between the character's current position and their future position, if they're moving fast enough, their future position will be past the object they should have collided with and they'll appear to phase through it. To be fair my improved code is a little long winded so if you know this will never be an issue in your game, then The original code might be better suited: *also I'm using xDist instead of hsp and yDist instead of vsp //I'm keeping sprite_width-height in abs incase the sprite has been mirrored //x(horizontal) //segScan is how many collision boxes fit in the distance to be traveled not including fractions of the collision box segScan = 0; if (abs(xDist) > abs(sprite_width)){ segScan = floor(abs(xDist) / abs(sprite_width)); } //loop through all of the segscan intervals for (i = 0; i
Excellent work Shaun, thank you! Love this series. I come back to the later episodes regularly to remind myself about certain techniques as I need to implement them. Thanks again.
@Na Na You've been a really big help. But could you do me one more favor? When I preview my sprite animation it doesn't loop, it goes forwards, left right left right, forwards.(the frames per second). If you could help I'd really appreciate it. Thx!
just curious if you'd be able to help, this is my second time round following this whole series but this time the after doing the vertical collision the player floats for a moment before teleporting to the floor?
I had a similar issue. The problem was that my character's "hitbox" or "frame" (for lack of better term) was overlapping with the ground (or wall, in this video). So, the character couldn't move because it had been instructed to not move upon collision, and collision started as soon I ran the game. The solution was to simply move the character away from the ground (or wall).
You're very smart. I'm barely grasping key points here. Thank you for the video. I'm using my android for a fps creator, and so far the video has been very helpful. Thank you man.
What is the best way to become proficient in GML and Game Maker Studio 2? Obviously tutorials and trial and error, but any other suggestions for learning?
I've put in a week's worth of time and practice. It paid off. Submitted my first game, Recoil, to the GMTK jam tonight. Thanks for everything you've taught! Check me out on itch. io if you like, creator name is brotherpixel.
Thanks! This was helpful. I had been trying with the drag and drop style for so long. I got them to work most of the time, but it was always slightly off. This was quite helpful. Can you make a tutorial for SNES style racing games like Top Gear (Top Racer in Japan and Europe)? :) These games aren't Mode 7, just typical behind the player camera that only moves forward (can't turn around).
I'm confused. I followed everything, but I can't get the movement to work. Here's my code: Create: hsp=0; vsp=0; grv=0.1; walksp=4; Step: key_left=keyboard_check(vk_left); key_right=keyboard_check(vk_right); key_jump=keyboard_check_pressed(vk_up); var move=key_right-key_left; hsp=move*walksp; x=x+hsp; If anybody knows what's wrong, please tell me.
"hsp = move * walksp;" makes my game not open, for whatever reason. I tried to close and open the project back again, and now the interface is all gone, and I can't get it back!
this was unhelpful. the video was well explained however i found there to be several errors in the code. I don't know what went wrong since I followed this video to a tea.
Probably he is using an older version Game Maker Studio 2. Whereas you're using GameMaker. For example, the newer version the variable is called gravity not grv etc..
Does anyone know why I'm just snapping through the floor. After a certain amount of time, the player just zooms straight down. Is it something to do with the gravity constantly increasing?
Old video, but it still appears to work for whatever I'm doing so that's convenient. Very well explained as well. I think understand GML a lot better now (still not great, but at least I got the basics on how variables work)
change controls to right A left D key so it works. you can do it like this: key_left = keyboard_check (ord ("A")); key_right = keyboard_check (ord ("D")) It happens if you do the same.
I am very new to GML. I have been using the drag and drop in gm:1 for a few years so it nice to learn GML. As a challenge I tried to add triple jumping without any tuts and I finally did it. You just have to add a var called airj and set it to 0 in the create event. Then add airj = 0; to the check for wall on y, then add if (!place_meeting(x,y+1,obj_wall)) && (key_jump) && (airj < 2) { vsp = -7; airj = airj + 1; } to the bottom of the code.
There must have been an update because I can't hold ALT to paint my walls into the room. Holding ALT now seems to do the same thing as holding the middle mouse button Edit: Okay I found my issue. I was pressing left ALT instead of right ALT
Hello there, im very new to this but i had an error occur, i placed in the correct coding you've shown in the video, followed all the right steps but... when i had opened my game, my square (the player) moved on its own to the right then it had left off of the game screen, my key controls didn't move it, or anything. i decided to try this again and had the same issue. my keys work just fine, because i play games that use the key functions. Could you maybe help me out? or try to figure out a solution to this error,
Hey! Just in case you haven't found an answer to your problem yet double check make sure you are doing everything in the same way he does in the video. It can be confusing to follow along at times but it's always good to pause and go through the code character by character after every line to learn it. Also it sounds like somewhere you're telling the object to move positively along the x axis aka to the right. He does this in the first while statement so I'd check your code there first. Good luck!
i had the same problem! just check that instead of having x = x + hsp, it’s y = y + vsp was trying to figure out what was wrong for about an hour, hahaha. hope it helps!
how do I make the player stay on those walls if the walls move? I used this piece of code to make the walls float: create event obj_wall: anchorY = y; frequency = choose(0, 0.05, 0.1, 0.15); amplitude = choose(5, 10, 15, 20); timer = 0; Step Event obj_wall: y = anchorY + sin(timer * frequency) * amplitude; timer++;
I am having a problem when running off a ledge, and immediately running the other direction. I am getting stuck inside the "wall" object by what looks like a single pixel. I tried using round(x) to make sure I am not between pixels but it didn't help.
Instead of using my sprite's bounding box, I switched to an even width collision mask sprite for my collisions, and used round(x) for my horizontal movement so I don't end up "between" pixels. This seems to have fixed it.
@@followingthetrend_norge2204 I think it has something to do with the logic checking for collision. If the player is starts falling at the exact same moment you move back at the wall, the logic correctly detects no wall so movement is allowed. So what happens is the player falls downwards and then because the logic allowed sideways movement it also moves sideways and straight inside the wall
im sort of having the same problem but different when gravity comes into affect after falling of a ledge (its fine if a jump on the same owall at the same height) i get stuck in one spot a pixel from the owall below and cant move at all, i also can only close the window with the stop playing button instead of the x in the corner im having loads of fun with this definitely havent been stuck on this problem for hours
hi, if you still dont make it to double jump try this. in Create Event, create a variable name it d_jump =1; now go to step Event and copy this after the jump code: if (!place_meeting(x, y + 1, obj_wall )) && (key_jump) && (d_jump > 0) { vsp = -7; d_jump -= 1; } if (place_meeting(x, y + 1, obj_wall )) d_jump = 1; now you will have double jump
hey, there's something wrong, really, because I made the green block and I can't enter the code and I can't, it just writes and nothing happens, can anyone help?
ignore it, once you write the movements in step it will disappear , thats just game maker saying "hey, you declared some variables and havent used them... you need them?"
No.. i's just in the vertical collision.. idkw but if you write : +sign(vps) it won't work. But if you you want it to work and no freez you have to type +vsp (without the sign)
@@oldpromisejones Shaun just made a fuck up with his coding. While I'm unsure of why it worked for his footage (probably editted it in later), I can say even with a high end pc it still freezes the game in a loop. So nothing to do with pc hardware, just an error in code. Anyone trying to make games would be a moron to instantly assume its someones hardware first. Poor programmer, that type of person.
i don't know why, but when i hold ALT in room editor, it moves around like with when holding middle mouse button, and i can't paint resources in room editor... anybody knows how to solve this ? Edit : I found it ! i had laptop mode turned on, and that made me be able to pan with ALT, but not paint ! It works now, YAY !
new way to do it: create: move_speed = 4; jump_speed = 16; move_x = 0; move_y = 0; step: //move keys input and speed move_x = keyboard_check(vk_right) - keyboard_check(vk_left); move_x *= move_speed; if (place_meeting(x, y+2, obj_wall)) { move_y = 0; if (keyboard_check(vk_space)) move_y = -jump_speed; } else if (move_y < 10) move_y += 1; //move and collide move_and_collide(move_x, move_y, obj_wall); if (move_x != 0) image_xscale = sign(move_x); //slopes if you want this make sure that the type of collision mask of your wall sprite is set to rectangle with rotation so you can have slopes if (!place_meeting(x+move_x, y+2, obj_wall) && place_meeting(x+move_x, y+10, obj_wall)) { move_y = abs(move_x); move_x = 0; }
For the absolute begginers, if you need your player to handle double jump instead of 1 jump in a very simple way: if (place_meeting(x, y + 1, oWall)) { moreJump = 1; // variable to set the maximum number of jumps, you can change the value to 2 or 3 or more if you want to add more jumps. if (key_jump) vsp -= 7; // don't forget the basic one jump when you're on the ground } else { if (key_jump and moreJump > 0) { vsp = 0; // reset the gravity before jumping again! vsp -= 7; // jump again ! moreJump -= 1; } }

I know you already got a lot of praise for this tutorial but here:
Your tutorial made coding fun for me (I've been trying to learn for a month)
Took me about 1.5h to get this done and it's incredible, I'm looking forward to the rest of the series :D
I will coment on as many videos as I remember so the algarythm hopefully pushes this amazing tutorial to more people looking to code
Well done!!
That is how I feel!
EXACTLY. i love this tutorial as much as it makes me love sam hogan !!! EXTREME props to him. this helped me learn coding entirely.
Programming tip:
Avoid abreviations like hsp, vsp, grv, walksp. These can confuse you or others in the future, It's better to spend some extra time to write out a longer name for it, for example:
horizonatal_speed, vertical_speed, gravity, walk_speed
Now you will know exactly what every variable is for, so you won't have to guess what it is for. (it may not seam like an issue now, but over time when you have a lot of them, you'll have a hard time remembering what every single variable means, and what the exact name for a variable you need is, when you have ones more like the ones above, you can just write out what the variable is for rather than a code name for it)
If u want multiple ways of controlling the item use this block:
key_left = keyboard_check(ord("A")) or keyboard_check(vk_left);
key_right = keyboard_check(ord("D")) or keyboard_check(vk_right);
key_jump = keyboard_check_pressed(vk_space) or keyboard_check(ord("W")) or keyboard_check(vk_up);
this lets the player control the enttiy in many ways.
Thank you SO much for this tutorial series! It has been INVALUABLE in my programming education. Keep up the great work!
This video is delicious! Downloaded GMS2 after realising Unity was overkill for my needs - creating my first 2d platformer for fun. Glad I've chosen your channel as my learning tool right from the beginning!
Super helpful tutorial. Thank you very much! :)
awesome tutorial! i did not know anything and now i've learned MUCH.
and it's moving! and jumping! and I did all of this! yay! =D
This is really cool, thank you for making this series, but I have some questions. For starting from scratch, did you choose blank game or platformer? After that did you choose, GML Code or GML Visual?

I remember 3 years ago I went to learn GameMaker Studio, and Shaun's platformer tutorial was there for me to learn. Now I can produce a platformer on the spot without any references.
I'm delighted to see that you're producing a tutorial for the people getting into GM:S 2.
Thanks Shaun.
Too Long; Didn't Study
Can relate, mate, he gets an 8/8.
(sorry couldn't resist)
Seriously though,
Shaun helped me start programming, which led me to get into advanced programming(OO)
The amount of stuff I learnt on this channel is alot.
Just checking in to help these people with their errors.
I'm gonna subscribe I'm new to gamemaker studio 2. My friend and I want to make very awesome games for fun and maybe for a bit if cash but mostly for fun I can't wait for more content like this :)
Hi,
I have a problem with loading my game...
it takes me 30 seconds. Do you maybe know what is wrong? The computer is very fast.
Thank you for great tutorials.
Yeah loved his gm tutorials and now im happy to see he did some for gm2 to
is Game Maker Studio still available or is it out of service now?
Anybody who wants to add A = left and D = right (like the WASD controls) just do this:
key_left = keyboard_check(ord("A"));
key_right = keyboard_check(ord("D"));
thanks bro!
thanks i was looking on how to do it
i thought it had to be ord('A'), but that was giving me troubles
From someone who's arrow keys are stupidly tiny compared to the normal WASD, thank you.
Thank you! I always thought arrow controls were a little wonky. (Maybe I could add both? Who knows what the preference of the person that plays my game will be?)
Pressing F4 in the code editor lets you add if statements, blocks, etc.

This video made coding fun for me. So much so that I made it wall jump!
//Wall Jump
if (place_meeting(x+hsp,y,oWall)) && (key_jump)
{
vsp = -7;
}
Thanks!!! You are an awesome teacher :D
for anyone looking to copy this, you might also add momentum away from the wall
hsp = -sign(hsp) * 2;
and if you're doing it after the collision (which makes sense) hsp will be 0, so save sign(hsp) in the collision and set the walljump's place meeting to (x+hSignVariable,y,oWall)

@@hole1274 youre a lifesaver!! Thank you!
@@hole1274 alright, sorry for keeping this going, but the wall jump works! however, i dont want the player to be able to just keep on wall jumping up the same wall over and over. i want them to kind of bounce away from the wall naturally after one walljump. would you know how to do this? if its easier(and if you have discord) my discord username is EdgeGod27 #3004
[SOLUTION]
If your player is "floating" and stays in the air too long, then you need to raise your grv variable. At 29:03, Shaun changes the value from 0.1 to 0.3. He does it really fast and might be hard to catch. Good luck with your game!
thanks
lol man thanks

When I jump my character teleports up instead of jumps. Do you know how I fix this?
Game Maker Studio is like a mix of unreal engine of blueprint and C++ with an actual good 2d implementation
This was AWESOME! I had a couple glitches as I went. My mistakes helped me learn stuff:
1. If you're seeing boxes to drag instead of a place to type in the Create tab as shown in the video, right click and select Switch to GML.
2. I had a typo in one of my variables in the Create tab. I had walkvp instead of walksp! Also, WALKSP is not the same as walksp - capitalization DOES count.
3. I had semicolons at the end of my if and while statements. Don't put semicolons there.
4. I put a semicolon instead of a comma in one of the x,y+1,o_wall statements.
Excellent, nay, PERFECT video for a first timer.
ty
Well its better to think of it this way, dont put semicolons when a { follows after it.
lol ty i was searching where im doing the mistake :D
I can't get past this part for some reason, my player just automatically goes left all the time and i cant bring it to the right
Edit: fixed it, i wrote x = x * hsp; which was why it wasn't working
ty
use f8 and f9 keys to zoom in and out in event code
I'm pretty sure this is useful!
Thank You!!
uh, on my computer its f7 and f8.. not trying to be rude but just letting people know in the replies if they have any issues ;D
Wish I'd looked down here before I googled it! Thannks!
If you want to add sprinting to the game you just need to put:
key_sprint = keyboard_check(vk_shift);
to the key section
and add:
if(key_sprint)
{
hsp *= 1.75;
}
in front of:
x = x + hsp;
It Works! But (after adding this feature after the next tut) there is an issue.. stacking on walls .. i guess its a collision problem!
Nikos Paraponiaris yes I’ve met a similar situation, it seems to be sticking around the closed angles, may need additional code to get it run smoother
I can't seem to get this to work, idk why maybe its just different versions of gms2 broke stuff or im being dumb and messing up things somehow

Here is my code, you can compare the two, or you can copy paste it to test and run it, it works for me. The only thing to keep in mind is that my movement keys are "A" and "D", but you can change those if you like
here is my working code and plz ignore my spelling also this is for wasd keys
///controls(movement)
key_left = keyboard_check(ord("A"));
key_right = keyboard_check(ord("D"));
key_jump = keyboard_check_pressed(vk_space);
///telling the system what to do with that information
var move = key_right - key_left;
///horrzotle speed control
hsp = move * walksp;
vsp = vsp + grv
if (place_meeting(x,y+1,O_gound_one)) and (key_jump)
{
vsp = -7
}
//horizontal collision
if (place_meeting(x+hsp,y,O_gound_one))
{
while (!place_meeting(x+sign(hsp),y,O_gound_one))

vsp = 0
}
y = y + vsp
[[ SOLUTION ]]
Lots of guys having a problem where the player just falls into the ground and become incapable of moving, i had the same problem and found some unanswred comments asking for help..
i latter found that the IF statment on the vertical collision part had "y+sign(vsp)" written rather than 'y+vsp", wich is the correct way...
im proud as a begginer to have discovered the logical problem by myself, although i shoudn't had comited it in the first place hahaa
Thanks, you are a true god.
this didnt work for me is there any other fix as ive been looking for weeks with no luck thanks
Mason Clark be sure to check the collision masks and the origin points as they can also produce some weird bugs
Why did this work? This solution worked for me but I don’t understand why becquse the videos code had the (x,y+sign(vsp),oWall)
Jesse Damon if you set the collision to check on y+sign(vsp), it will be true everytime the collision mask is exactly one pixel above the ground, and will send you to the same place again and again and again
Although my vision for what I want to make isn't a platformer, this was an awesome intro and I'm a little upset I'm so early to the series because I want to spend a day just working through these tutorials! It's like when you start watching a show during it's initial air vs when the series is complete, the wait is awful lol.
i can't even get pass the vertical coding part. lol.
Just a tip for any future game developers, when you get stuck like this, duplicate your project then start experimenting. or have other smaller projects to work on.
@@OnBrandRP thank you for the tip

@@timschuchner I don't code with GSM, I know Java and C++, I usually use my own engine
how is your progress
I was having a problem where my player would just fall through the ground
I fixed it by :
1. Going to the player sprite in the workspace tab and expanding collision mask (left hand side)
2. setting mode to "manual"
3. looking at the sprite preview window and clicking and dragging a black box over the entire sprite
I think the reason I got this error is that I changed the origin of the object ( in the video somewhere around 2:03) to top left instead of center but i'm not sure.
i was having an issue where it wasnt stopping on the right side, i did what you suggested and now it's not moving at all lmao.

a lot of games work even better at higher frame rates than your monitor can push out. Dont believe me? if you're playing counter-strike with a locked frame-rate try taking it off. This isn't something that's discussed all that often because of the power needed to push a game beyond 200 fps. playing a game at 80fps or whatever just means screen tearing

Hey, i need help. For some reason i stick to the ground - when im falling i can move but when i touch the floor i can't do anything. Anyone can help?
I've been writing platform games since 85' while in high school using 6502 on an Apple IIe, what I've learned in this life is that the most important thing an artist can do (that is what we all are) is to master the rudiments, before we can construct the fantastic. I really enjoyed getting this man's perspective on "elegant logic" for good object control in a platform game construct. You "experts" are encouraged to just go over this step by step and you may be surprised at a perspective you didn't have on some very elemental, but critical components of game making. Thanks again Shaun.
It's possible to experience a game freeze using this method of movement/collision if you character falls onto the corner of a block at certain angles. From what I remember, this is because the collision wasn't set up for diagonal collision, so to avoid the issue, add this below your horizontal and vertical collision
//Diagonal Collision
if (place_meeting(x+hsp,y+vsp,oWall))
{
while (!place_meeting(x+sign(hsp),y+sign(vsp),oWall))
{
x += sign(hsp);
y += sign(vsp);
}
hsp = 0;
vsp = 0;
}
W, thanks
This is really nice, its working and good for basic platformer, but if you need to build up momentum in your game, this code actually might kill it.
@@susniynarezchik I haven't had any issues using acceleration and this code so far, as all the code is for is to stop you from getting frozen in a while loop when you land on a corner at a near perfect 45 degree angle, which is pretty much the only time the code seems to fire
@@susniynarezchik On second thought I have had some issues with losing momentum. Do you have a more elegant solution?
@@timtam4596 Yooooo i didnt think you would adress my comment that fast! As i said, your code works perfectly fine without need of any momentum implementation, but in my case it didnt work out. So, for example, i tried saving data of hsp to some momentum_saver variable right before the jump (i had set different accel/decel for it), but right before the variables data gets saved, it changes to 0. First of all, i tried saving hsp data at a different place, but I couldnt get it accurate enough. For now, i basically did a simple pre-hmove check, and turned hsp to 0 if future collision detected (also i needed that bc my character goes way too fast for game to control), and before that i save my momentum data. it turned out smth like that:
//Horisontal collision
if (place_meeting(x+hsp, y, oPlatform) ){
while (!place_meeting(x+sign(hsp),y,oPlatform)){
x = x + sign(hsp);
momentum_save = hsp;
}
hsp = 0;
}
//momentum save (post collision check)
if (place_meeting(x - hsp, y - vsp, oPlatform) and state_c == "running"){
momentum_saver = hsp;
}
//Pre horizontal move check
if (place_meeting(x+hsp,y,oSpikes) or place_meeting(x+hsp,y,oPlatform))
{
hsp = 0;
}
x = x + hsp;
Yeah, as u get it, i am new to gm, and i very appreciate your help to us, newbies. I guess i might find more elegant solution later, but it is what it is right now. (And yeah lol, sorry for any potential grammar mistakes i made here, since english isnt my first language.) Anyways, wishing you best of luck!

This is a very bad idea, but I don’t want to bother with tech support so try to use drag and drop mode and use the tutorials from the official website of the devs. Basically there are blocks that do the typing for you. Like a puzzle. Good luck.
Plus it might be an update that broke it. I’ll try another time
For some reason after I added the gravity I wont move when i'm on the ground but only when falling.
Thanks, Shaun! Wonderful stuff.

To anyone who wants to use WASD instead of arrow keys you can replace the
vk_left vk_right vk_space
with
ord("A") ord("D") ord("W")
Hope this helps 🙂
it did not work can you help me pls
@@pen_man375
key_left = keyboard_check(ord("A"));
key_right = keyboard_check(ord("D"));
nothing is appearing when im pressing play, help plz
edit: nvm j was running the wrong room
Instructions unclear, i created Red Dead Redemption 3
good job?
The collision code works great but there is one problem with it. Since it doesn't check the space in-between the character's current position and their future position, if they're moving fast enough, their future position will be past the object they should have collided with and they'll appear to phase through it. To be fair my improved code is a little long winded so if you know this will never be an issue in your game, then The original code might be better suited:
*also I'm using xDist instead of hsp and yDist instead of vsp
//I'm keeping sprite_width-height in abs incase the sprite has been mirrored
//x(horizontal)
//segScan is how many collision boxes fit in the distance to be traveled not including fractions of the collision box
segScan = 0;
if (abs(xDist) > abs(sprite_width)){
segScan = floor(abs(xDist) / abs(sprite_width));
}
//loop through all of the segscan intervals
for (i = 0; i

Excellent work Shaun, thank you! Love this series. I come back to the later episodes regularly to remind myself about certain techniques as I need to implement them. Thanks again.
How can you still run the game despite the unused variables? when I try to play it, it just says it faled to load the game.
Sorry but the sprite does not move and I do not understand why
@Na Na Then it moves left forever
@Na Na Thanks this really helped.
@Na Na Yes, I downloaded it last week.
@Na Na Thanks!
@Na Na You've been a really big help. But could you do me one more favor? When I preview my sprite animation it doesn't loop, it goes forwards, left right left right, forwards.(the frames per second). If you could help I'd really appreciate it. Thx!
just curious if you'd be able to help, this is my second time round following this whole series but this time the after doing the vertical collision the player floats for a moment before teleporting to the floor?
nvm i forgot y=y+vsp, silly me
ah ok@@thatguyorgal1840
after the Vertical movement my character didn't move anymore
pls help
Double check your code matches Shaun's. I've just followed this through after downloading GM2 yesterday and it works fine.
I had a similar issue and it was that I'd left a hsp in where we copy and paste it for vertical collision, check there maybe?
I had a similar issue. The problem was that my character's "hitbox" or "frame" (for lack of better term) was overlapping with the ground (or wall, in this video). So, the character couldn't move because it had been instructed to not move upon collision, and collision started as soon I ran the game. The solution was to simply move the character away from the ground (or wall).
You're very smart. I'm barely grasping key points here. Thank you for the video. I'm using my android for a fps creator, and so far the video has been very helpful. Thank you man.
he did not even tell that you have to choose gamemaker language now I have to restart
What is the best way to become proficient in GML and Game Maker Studio 2? Obviously tutorials and trial and error, but any other suggestions for learning?
I've put in a week's worth of time and practice. It paid off. Submitted my first game, Recoil, to the GMTK jam tonight. Thanks for everything you've taught! Check me out on itch. io if you like, creator name is brotherpixel.
I just played your game and it's a lot of fun!
Thanks! This was helpful. I had been trying with the drag and drop style for so long. I got them to work most of the time, but it was always slightly off. This was quite helpful.
Can you make a tutorial for SNES style racing games like Top Gear (Top Racer in Japan and Europe)? :)
These games aren't Mode 7, just typical behind the player camera that only moves forward (can't turn around).
I'm confused. I followed everything, but I can't get the movement to work. Here's my code:
Create:
hsp=0;
vsp=0;
grv=0.1;
walksp=4;
Step:
key_left=keyboard_check(vk_left);
key_right=keyboard_check(vk_right);
key_jump=keyboard_check_pressed(vk_up);
var move=key_right-key_left;
hsp=move*walksp;
x=x+hsp;
If anybody knows what's wrong, please tell me.
"hsp = move * walksp;" makes my game not open, for whatever reason. I tried to close and open the project back again, and now the interface is all gone, and I can't get it back!
i did the same thing. turns out i had my step code in create, and create code in step, when it should have been the other way around
Thanks Shaun for this amazing tuto. i allways try to implement a liitle more so i can learn. I did double jump and it work perfect. keep it up
this was unhelpful. the video was well explained however i found there to be several errors in the code. I don't know what went wrong since I followed this video to a tea.
Probably he is using an older version Game Maker Studio 2. Whereas you're using GameMaker. For example, the newer version the variable is called gravity not grv etc..
I don't know why but my computer is taking a lot of time for running the game in 60 FPS..
Does anyone know why I'm just snapping through the floor. After a certain amount of time, the player just zooms straight down. Is it something to do with the gravity constantly increasing?
Did you set the collision mask in the centre?
did you limit your gravity to be set to like, 10 when it goes over that amount?
are you resetting gravity when you touch the floor?
Old video, but it still appears to work for whatever I'm doing so that's convenient.
Very well explained as well. I think understand GML a lot better now (still not great, but at least I got the basics on how variables work)
The code keeps giving me this error: "Variable (blank) has only been referenced once."
Thats because variables like key_jump arent used yet dont worry about this error its not bad its gonna be fixed later!
@@lunasoldev i watched the entire vid and nothing was fixed -_-
@@goob30 just keep going with the tutoriald sn whete exactly does it say the error
change controls to right A left D key so it works. you can do it like this: key_left = keyboard_check (ord ("A"));
key_right = keyboard_check (ord ("D"))
It happens if you do the same.
@@goob30 basically ignore it until it is used again, it simply means the code doesn't have another instance of running
I am very new to GML. I have been using the drag and drop in gm:1 for a few years so it nice to learn GML. As a challenge I tried to add triple jumping without any tuts and I finally did it. You just have to add a var called airj and set it to 0 in the create event. Then add airj = 0; to the check for wall on y, then add if (!place_meeting(x,y+1,obj_wall)) && (key_jump) && (airj < 2) {
vsp = -7;
airj = airj + 1;
}
to the bottom of the code.
Hey! I have a question, I can only double jump 1 time, how do I make it unlimited
@@XO-cq6gx use drag n drop lol. i tried it and you can jump unlimited times without adding the y+1 thing
There must have been an update because I can't hold ALT to paint my walls into the room. Holding ALT now seems to do the same thing as holding the middle mouse button
Edit: Okay I found my issue. I was pressing left ALT instead of right ALT
I had the same issue today.
Just tried this tutorial out--and I had a lot of fun with it! It's so satisfying to see the code at work. Thank you for the great lesson!
Hello there, im very new to this but i had an error occur, i placed in the correct coding you've shown in the video, followed all the right steps but... when i had opened my game, my square (the player) moved on its own to the right then it had left off of the game screen, my key controls didn't move it, or anything. i decided to try this again and had the same issue. my keys work just fine, because i play games that use the key functions. Could you maybe help me out? or try to figure out a solution to this error,
Hey! Just in case you haven't found an answer to your problem yet double check make sure you are doing everything in the same way he does in the video. It can be confusing to follow along at times but it's always good to pause and go through the code character by character after every line to learn it. Also it sounds like somewhere you're telling the object to move positively along the x axis aka to the right. He does this in the first while statement so I'd check your code there first. Good luck!
i had the same problem! just check that instead of having x = x + hsp, it’s y = y + vsp
was trying to figure out what was wrong for about an hour, hahaha. hope it helps!
The same thing happened to me, and then I realized I put a + instead of a *.
İ deleted the while parts for both vertical and horizontal, worked for me.
how do I make the player stay on those walls if the walls move?
I used this piece of code to make the walls float:
create event obj_wall:
anchorY = y;
frequency = choose(0, 0.05, 0.1, 0.15);
amplitude = choose(5, 10, 15, 20);
timer = 0;
Step Event obj_wall:
y = anchorY + sin(timer * frequency) * amplitude;
timer++;
I am having a problem when running off a ledge, and immediately running the other direction. I am getting stuck inside the "wall" object by what looks like a single pixel. I tried using round(x) to make sure I am not between pixels but it didn't help.
Instead of using my sprite's bounding box, I switched to an even width collision mask sprite for my collisions, and used round(x) for my horizontal movement so I don't end up "between" pixels. This seems to have fixed it.
Hello. I have the same problem, how to fix it?
Lol a year later... but i have the same problem
@@followingthetrend_norge2204 I think it has something to do with the logic checking for collision. If the player is starts falling at the exact same moment you move back at the wall, the logic correctly detects no wall so movement is allowed. So what happens is the player falls downwards and then because the logic allowed sideways movement it also moves sideways and straight inside the wall
im sort of having the same problem but different
when gravity comes into affect after falling of a ledge (its fine if a jump on the same owall at the same height) i get stuck in one spot a pixel from the owall below and cant move at all, i also can only close the window with the stop playing button instead of the x in the corner
im having loads of fun with this
definitely havent been stuck on this problem for hours
my player kept falling inside the wall however it still moved and was about to jump out, idk what to doooo
I have the same problem
Same here, you got a fix?

How can you put in a double jump mechanic??
make a variable and call it number of jumps, when you jump reduce the number by 1, then when it's at 0 make it so you can't jump anymore
@@bearwynn can you teach me how to do that in game maker studio 2 language pls?
hi, if you still dont make it to double jump try this.
in Create Event, create a variable name it d_jump =1;
now go to step Event and copy this after the jump code:
if (!place_meeting(x, y + 1, obj_wall )) && (key_jump) && (d_jump > 0)
{
vsp = -7;
d_jump -= 1;
}
if (place_meeting(x, y + 1, obj_wall )) d_jump = 1;
now you will have double jump
@@jeykang1540 you call that simple (; its not for a beginner
@@GodOfTetris90 it didnt work, maybe cause of the "place_meeting" requirement of the object wall i guess :-:

Outdated code

ignore it, once you write the movements in step it will disappear , thats just game maker saying "hey, you declared some variables and havent used them... you need them?"

Guys can someone help? Whenever I touch my platform, the game freezes and I can't close it without using the task manager.
me too
im sorry you just have a trash pc :/
No.. i's just in the vertical collision.. idkw but if you write : +sign(vps) it won't work. But if you you want it to work and no freez you have to type +vsp (without the sign)
@@oldpromisejones Shaun just made a fuck up with his coding. While I'm unsure of why it worked for his footage (probably editted it in later), I can say even with a high end pc it still freezes the game in a loop. So nothing to do with pc hardware, just an error in code. Anyone trying to make games would be a moron to instantly assume its someones hardware first. Poor programmer, that type of person.
It's because of the while loop being used to push the player right up to the ground.
i don't know why, but when i hold ALT in room editor, it moves around like with when holding middle mouse button, and i can't paint resources in room editor... anybody knows how to solve this ?
Edit : I found it ! i had laptop mode turned on, and that made me be able to pan with ALT, but not paint ! It works now, YAY !
Outdated code
Check the top comment
It's working fine for me??
new way to do it:
create:
move_speed = 4;
jump_speed = 16;
move_x = 0;
move_y = 0;
step:
//move keys input and speed
move_x = keyboard_check(vk_right) - keyboard_check(vk_left);
move_x *= move_speed;
if (place_meeting(x, y+2, obj_wall))
{
move_y = 0;
if (keyboard_check(vk_space)) move_y = -jump_speed;
}
else if (move_y < 10) move_y += 1;
//move and collide
move_and_collide(move_x, move_y, obj_wall);
if (move_x != 0) image_xscale = sign(move_x);
//slopes if you want this make sure that the type of collision mask of your wall sprite is set to rectangle with rotation so you can have slopes
if (!place_meeting(x+move_x, y+2, obj_wall) && place_meeting(x+move_x, y+10, obj_wall))
{
move_y = abs(move_x);
move_x = 0;
}
1:15 pause the vid and shake your phone lightly and the squares move
Some people aren't watching on their phones.
then shake your friggin' gameboy gosh
is this still useable or is it outdated
For the absolute begginers, if you need your player to handle double jump instead of 1 jump in a very simple way:
if (place_meeting(x, y + 1, oWall))
{
moreJump = 1; // variable to set the maximum number of jumps, you can change the value to 2 or 3 or more if you want to add more jumps.
if (key_jump) vsp -= 7; // don't forget the basic one jump when you're on the ground
} else {
if (key_jump and moreJump > 0) {
vsp = 0; // reset the gravity before jumping again!
vsp -= 7; // jump again !
moreJump -= 1;
}
}
