Great video! i had to pause several times because while I was brainlessly following other tutorials, you explained what specific lines of code did and everything just clicked, thank you!!
Been working on procedural animation recently and needed to look into raycasting. This is the best tutorial ive seen for any topic in roblox studio by far. Thank you and i hope you post more! I typically never comment but this was amazing
This is such a good raycasting tutorial!!!!! I could 100% see a new roblox scripter easily learning how raycasting works with this video. Great job using animations to explain how raycasting works!
how is this so underrated yet the edit is absolutely amazing and the teaching finally actually teached me the most of raycasting, you deserve a million subs dude
I wish I've find you sooner your video is very helpful and made with efforts! I've been struggling trying to learn raycasting for a while and this video help me out a lot you deserve more subscriber 💖
While the video does great at explaining how raycasts work... the main raycasting of the gun is all happening on the client, which doesn't really work well in a multiplayer environment.
It doesn’t, you’re right. But for games with small servers or small Raycasts / second, it’s totally fine. In my experience, even 20-40 Raycasts per second works fine
This is one of the best tutorials on ray casting I have came across on RUclips (along with ByteBlox’s)! I am looking forward to more uploads from you :)
Well I don't speak English very well, so I'm screwed, but finally a young person who knows how to make tutorials! This way of learning, here is a real tutorial and not just a presentation of a script
@@scripting do you know of a good video explaining remote functions…specifically describing what we are doing here to get the mouse position? I’ve watched a few but haven’t found a good one yet
Yup. It’s used everywhere, especially in places where we would never even think of. When a gun is firing, we fire a ray where the origin is the gun and the direction is where our mouse points (just like in the video) When you select a troop in a tower defense game (or in my game, battle mania), a Raycast is done from the foot to the ground so the script knows where the ground is and to place the troop effectively
I was talking specifically about the "Normal" of the raycast. I know raycasts are used for basically everything, super useful tool. But before now I had no clue what the normal of a raycast instance was, and during the video I was wondering when anyone would ever use it.@@scripting
@@AntiNuke_ Gotcha. Yeah, the normal is used like in the footsteps example, and perhaps also making a thrown object ricochet off surfaces it hits. For example, a ball is thrown. It hits a wall. Apply a lesser force on that ball with the direction of the normal of the surface. Repeat. If you do this to a laser, it can give a laser bouncing off / ricochet effect
Yep, I just actually used the normal of an object to make a script that makes the camera bounce off an object it hits using a raycast from the head to the camera position detecting what the camera is hitting.@@scripting
this is good good job and also can you make more vids on advanced stuff? pls like stuff that isnt taught yet bc most ppl say read the docs but i like hearing than reading
This is actually the best explanation, but these are extremely hard to make so i ront expect a full scripting tutorial with these types of explanation and jokes lmfao
You could, but this video was made before I found that property out. Behind the scenes however, roblox most likely uses Raycasting to deduce the floor material
Gave up on this tutorial 6 minutes in. The added graphics got in the way of seeing the script. Script was added without it being noted in audio. Couldn’t get past an error when trying to get the mouse position in the Handle script.
Very good tutorial. The only thing i need to know now is how people make it so when you shoot a gun with raycasting. It will leave a trail so it looks like it is a kind of bullet, a lot of games have this :D
I have a question, how much did you Need to study(practice) scripting and other game aspecpts before being sure to make a big project like the ‘Battle Mania’. I am asking this because i currently have about 1year scripting knowledge, and i don’t really know to build on blender, make Vfxs and that stuff😅
I’ve been scripting for 8 years. So, by the time I began battle mania, I already knew how to script anything I wanted lol. Keep on scripting though, script whatever you want to script and whatever is interesting, and you’ll get there.
@@corbinwalton9996 I know how to do that, but I wanted to use raycast to make projectiles instead and if it would touch the character I would now lower the health.
also while making a raycast i noticed it said that the ray cast params had to be included in the raycast result when i tried doing it how u did it, it failed to work but when i added the params above the result and into the result it worked, so uh just wanted to ask why it worked for u but not me? : edit nvm my brain farted
14:16 For some reason the script does not work. I even tried to copy the script letter by letter. It says that the instance the raycast hits every time is the monkey and when I try to filter out the monkey it says there's no instance. Is there a way to fix this?
if anyone has any idea if this works, is there a way to make it so that I can have the ray fire off when I press space bar as oppose to having a weapon active? thanks! I should also mention I want the ray to originate from the Player
so sorry if im bring stupid here--at 5:20, where exactly do you put the localscript? StarterPlayer, ReplicatedStorage, or whatever? I'm unsure where it's supposed to be
Highlight the area of your script you want to de-indent. Then press control + [ Doing that will de-indent those lines. Pressing control + [ will apply an indent to those lines. You’re welcome
6:38 when i ran it i got an error "Players:GetNameFromUserIdAsync() failed: HTTP 429 (Too Many Requests)" anyone know the issue? this is the code local laser = script.Parent local getMouseRemote = game.ReplicatedStorage.getMouseRemote laser.Activated:Connect(function() local player = game.Players:WaitForChild(laser.Parent.Name) local rayorigin = laser.Handle.Rayorigin.Position local mouseposition = getMouseRemote:InvokeClient(player) local raydirection = (mouseposition - rayorigin).Unit * 400 local raycastresult = workspace:Raycast(rayorigin, raydirection) if raycastresult then print(raycastresult.Instance) raycastresult.Instance:Destroy() end end)
Yes you can. The way it’s done is like this: fire a Raycast. From the Position of the Raycast Result, fire another one again in the same direction. And another. … and so on
Raycasts only give you the first thing. Imagine a really slim needle that only touches one spot. That’s kind of what the “laser”is. To get everything, you can use region3. Basically, you create a region around the thing the ray touches and get everything in that region.

So that’s because it shouldn’t be OnClickInvoke, it should be OnClientInvoke The reason it doesn’t give you an error when it’s in server script service is because local scripts cannot run there

7:30 Actually it is an Humanoid property called FloorMaterial. If the cheraxter is jumping, it will say that it's Air material.

this is genuinely the best scripting tutorial ive seen on youtube, i hope you gain more traction because this is criminally underrated.
This video really helped me understand raycasting, the maths of it, etc.... Thank you, great work!
It's a shame that mostly coders will watch this and not more people, because it's a fantastic video
It is. Thanks!
this is pointless if you can't code

Ur teaching is so underrated ong. U deserve more subscribers
Wow that was probably the best roblox tutorial I've ever seen. Super high quality 👍
Thanks i think this would be a great help for my game
Wish i saw this sooner, i've been trying to learn about raycasting for a while now.
This Tutorial Helped me Alot, Before watching this, i didn't even know What raycasting Is, Now i do. Thanks!
Super cool tutorial, thx ! (btw love the editing)
Omgg im making a laser and youtube recommended me this yay
thank you, i always thought this was hard but you explained it in such a simple way!

Took 2 months to make this video 😅
the best video explaining raycast on youtube
thank you so much!
Interesting and Entertaining Video Lesson!
Perfectly balanced as all things should be.
Outstanding video, except I got lost starting 5:14 about where to put the "MousePos" localscript....does that go in the gun?
I think it goes in "StarterPlayer -> StarterPlayerScripts"...?
@JavaInAJiffy you can put it in starter pack
@@scripting do you know of a good video explaining remote functions…specifically describing what we are doing here to get the mouse position? I’ve watched a few but haven’t found a good one yet
@JavaInAJiffy It’s on my list of videos to make :)
very good explanations would look to see more videos like this but chill on the sfx and tv glitch
ngl , this video is both entertaining and easy to understand , im looking forward to the shapecast video
Glad you enjoyed it!
Thank you for the car analogy to explain the normal of an object, I was literally thinking "what practical use does this have".
Yup. It’s used everywhere, especially in places where we would never even think of.
When a gun is firing, we fire a ray where the origin is the gun and the direction is where our mouse points (just like in the video)

Thanks!
You def getting a sub you explained it exactly how I needed
thanks broski, i spent SO LONG wondering why my raycast gun didnt work for some reason. seems like the multiply by 500 thing was all i needed
This is actually the best explanation, but these are extremely hard to make so i ront expect a full scripting tutorial with these types of explanation and jokes lmfao
hold on, at 7:34 ish, doesnt the roblox humanoid have a floormaterial property? couldnt you use that instead??
You could, but this video was made before I found that property out. Behind the scenes however, roblox most likely uses Raycasting to deduce the floor material
@@scripting ohh! okay
Gave up on this tutorial 6 minutes in. The added graphics got in the way of seeing the script. Script was added without it being noted in audio. Couldn’t get past an error when trying to get the mouse position in the Handle script.
Which error? If you watch the whole video, you should understand it
I RARELY COMMENT BUT THIS IS SO WELL EXPLAINED,,, TYSM
real lifesaver, keep up the good stuff bro
Very good tutorial. The only thing i need to know now is how people make it so when you shoot a gun with raycasting. It will leave a trail so it looks like it is a kind of bullet, a lot of games have this :D
You can make a bullet and use ApplyImpulse on it to make it fire

Am only at halfway but like DAMN THIS IS AWESOME TUTORIAL
thank you for teaching me about normals you are amazing
No problem! :)
isn't the a humanoid property called floor material?
There is yes, u can use it as well
also i tried to make a visulizer for the raycast(to help me do it easier) and then it was floating so idk whats that about
21 yo cs major and this is good quality education i hope to educate people one day in the future
Thank you man. I’m 20 y/o cs major
The top of my left eye enjoyed the first half
So how do you make a gun with projectiles with raycast?
check if what it hits is a player by checking if its parent has a humanoid and then lower the humanoids health if there is one
@@corbinwalton9996 I know how to do that, but I wanted to use raycast to make projectiles instead and if it would touch the character I would now lower the health.
Underrated , keep it up

if u continue like this, u will be the biggest roblox devolper youtuber.
Most definitely
Thank you, now I know how to make a Part go to the position where you clicked and make it look at the part
Of course!
Why does it say “ray origin” is not a valid member of part?
the most important script is on screen for a total of two seconds 💀
Good thing there’s pause! 😂
Man amazing work man 😂 😂 👏👏👏
followed the code and at the point around 5:30 instead of the raycast returning the values it returns nil
I believe it’s because for the Attachment.Position, it should have been Attachment.WorldPosition
REALLY WELL EXPLAINED!
YOU ARE UNDER RATED
if anyone has any idea if this works, is there a way to make it so that I can have the ray fire off when I press space bar as oppose to having a weapon active? thanks!
I should also mention I want the ray to originate from the Player
so sorry if im bring stupid here--at 5:20, where exactly do you put the localscript? StarterPlayer, ReplicatedStorage, or whatever? I'm unsure where it's supposed to be
Hi. You’re not being stupid, don’t worry. All questions are good questions! The local script can go in starter gui or starter pack.
is there a way to make the raycast like into a visible object like a laser or a bullet
You can. You’d make a part and set the CFrame to look where you want it to and the size.Z (or size.X) to the raycastResult.Distance
Best Raycasting guide out rn
You know it 💯
Your so underated
Uh, guys i think u guys got an error, and it isnt working now, to fix that, i did so the rayoriigin is the worldposition instead of position.
Yes, that was fixed later in the video
okay what was that shortcut at 20:09
I swear I'm always learning new studio shortcuts that save me hours

this video explained raycasting very well. although why did you give it to ur little brother again?
Thanks. The reason we gave it to the little brother is because it isn’t dangerous. It’s a toy! 😅
SO UNDERRATED
You are extremely underrated
How do u remove the indents if u end up removing an "if" statement, its always so annoying to have to remove them.
Highlight the area of your script you want to de-indent. Then press control + [
Doing that will de-indent those lines. Pressing control + [ will apply an indent to those lines.
You’re welcome
@ thank you my brain dies when it looks odd like that after so this is very helpful
6:38 when i ran it i got an error
"Players:GetNameFromUserIdAsync() failed: HTTP 429 (Too Many Requests)"
anyone know the issue? this is the code
local laser = script.Parent
local getMouseRemote = game.ReplicatedStorage.getMouseRemote
laser.Activated:Connect(function()
local player = game.Players:WaitForChild(laser.Parent.Name)
local rayorigin = laser.Handle.Rayorigin.Position
local mouseposition = getMouseRemote:InvokeClient(player)
local raydirection = (mouseposition - rayorigin).Unit * 400
local raycastresult = workspace:Raycast(rayorigin, raydirection)
if raycastresult then
print(raycastresult.Instance)
raycastresult.Instance:Destroy()
end
end)
time to take the script and redo it without learning anything-

Is it possible to make the raycast go through everything? Or i have to use somrthing else

@@scripting when I put it there is says
OnClickInvoke is not a valid member of RemoteFunction "ReplicatedStorage.GetMousePosition"
