To stop objects from moving through colliders when moving at a fast pace you can set the objects rigid body's collision detection from discrete to continuous. It's more performance heavy which is why it's not the default.
Looking for a fix myself. I have tried everything. Continuous Dynamic on all rbs with interpolate turned on. The rb I am moving still "goes inside" the RB it's colliding with.
when I rotate the capsule with the mouse the axes change direction (W becomes S and A becomes D and vice versa), so to go forward I have to use A, D or S depending on where the player is looking . Does anyone know how I fix this? I tried transform.Translate, but as said in the video, it doesn't work along with physics
This video is a gift from heaven. I just started unity a week back and my script is super complicated because i never knew how to do movement, so I experimented. This REALLY helps a lot! Thank you!
This is what a tutorial should look like. Been searching for a simple and well detailed answer for eternity and i got even more confused each time, but finally, I got a good answer. Thanks man 👌🏾
I've seen a lot of rigidbody lesson on both unity official tutorials and youtube but this is the best well explained and distilled version ever! Keep on your journey, I'll be following!
Sir, please make more of these. As a complete beginner your way of describing makes so much sense than the traditional “ follow me” tutorials where when you finish you are just as clueless if not more than when you began
This was information I needed for a long time. I kept trying to have the translate behavior, while avoiding clipping issues. I couldn't find an answer until your video. Thank you.
This video is the best explained video on the subject that I've ever seen. Even my teacher in college didn't explained that well. This will help me alot, thanks
hey, I've been using this video since it was released on like, a dozen or so different projects of mine for any number of functions and tasks. So, thank you so much. It has really made my life so much easier.
Thank you for this! I made the mistake of using the Translate function for my game prototype only to then realize after a bit of work that physics, collisions, and almost every planned mechanic was non-functional. You've done a fantastic job of explaining how the rb methods work.
You can use a raycast before moving to see how far you should move, if the raycast hits something then get the position and use that to move instead of the usual calculation.
I watched a tutorial on ai and it used add force but I wanted to use move position. Long story short took me four days and lots of thinking, you definitely helped.
Really useful information, good voice, high quality recording both visually and vocally, nice editing, not too short and not too long a video, clear explanation about the subject, proper examples and many other details that I am sure you have considered but I cannot immediately get it. I badly needed this piece of information and you just delivered that in the best way possible. Thank you so much sir ❤️
Thanks Gregory! We're slightly new but our numbers are climbing. We just need to breach through RUclips's algorithm, but I appreciate your kind words and support!
Maybe, I don’t know how these things work. My friend Chris (Cynical Reviews (previously Cynical CJ)) started from nothing and now has like 100k subs after a year. And Sykoo does Unity stuff and is doing very well (I think he’s friends with the guy from Brackeys so that might help.) maybe you need to say more controversial opinion stuff? Seems to work for other RUclips stars. I don’t know. I would like more channels like yours to grow because it’s great for learning Unity and generally making the community feel at home.
This was far easier to understand than some of the other tutorials I'd watched. It also gave me a couple of ideas on how to use the other movement types for different enemies. Thanks!

Wow! I watched so many videos this week trying to understand this, but your video was definitely the best one. Thanks a lot! Please keep making more of those
I loved the video! I was having problems with my 2D game because the player character was hitting the colliders but passing through after sometime, the Rigidbody.MovePosition() function was so helpful and you explained very clearly how to use it and how it works, thank you so much! :)
If you use velocity but still want the object to have gravity, you can also do it like this (it's like applying a force): rb.velocity += direction * speed;
First of all, I like all you videos and how well done they are just made (recorded, edited, and even sound and visual quality. I've been watching you videos on Patreon for the most part, but I just had to comment on this video. It's just very well explained and the demonstration and the way you broke things down just couldn't have been done better! Thank you very much, and keep up the good work. especially those video where you explain how things work or what certain functions/methods do or how they work. I'll be waiting for more videos like this.
With setting velocity you can set it to: rb.velocity(new Vector2(direction * speed, rb.velocity.y)); This will stop it from affecting the objects gravity.
This is such a helpful video! I've been going through so many videos and tutorials that just say "move your character this way" without explaining why that method was used or how it doesn't make sense for every game. The first tutorial I followed used translate because collisions did not have an affect on the player movement but it doesn't make sense for something like a 2D platformer.
Great tutorial. One flaw at the end: Set Rigidbody Collision Detection to Continuous instead of Descrete. That will prevent moving through walls at high speeds.
U can use add force and create a physics Material of zero friction and apply it to ground. U can also play around with drag. Doing this will help get faster stopping and accelerating time.
Great video. Explained simply, shortly, with practical examples and comments. I don't know how you could make it any better, keep it up. You've got my recommendation :D
Thank you so much! I've been flipping through tutorials and manuals for a week straight trying to find the simplest way to give an object flight. And...ha...for some reason, my sphere ended up flying around the X access instead of the Y, like yours. But THANK YOU. That was a succinct yet thorough explanation. I prefer the AddForce option, because I am trying to similate movement through fluid. However, I still have to look into how to include the Z axis. Maybe I should go for a follow the (3d)camera and move option.
2:14 In my 2d player script i am using transform.Translate to move character the strange this is it is acting opposite of what you just explained it can deteted collisions and gravity is applied i am using 2018.4 version of unity.
Oh my god! I sit here since two days and I as wonderi ng why my collision skript on my Object, which I have moved with translate, didn´t worked. Thank You sooo much for your help, your awesome!
You are very talented to teach and I love how you can explain 3 different ways for achieve movement with scripts. Could you make a series with this theme? I mean, wich different functions could do the same? Thanks!
Well, what drives me absolutely up the walls is that the minor details tutorials often skip like the is kinematic checkbox will have me looking for hours thinking I did something wrong with the code. I'm not setting up a script directly on the GameObject you see? So it's just easy to imagine that I've done something wrong. In the end, all of this is just so simple. It's like, when I was desperately trying to get the mesh data, I'm talking about the vertices and the triangles... someone on Twitter showed me a sample of his code. It didn't work for me at all. I kept getting error messages that read something like I didn't have permission to read or write the data. When I found that stupid checkbox everything seemed to work... Oh, but no, there had to be something else. I had all the coordinates, it was so beautiful. But they looked strange, and I got to understand that I had a long list of doubles and not floats. I spent days scratching my head, trying to figure out how I would solve this or just make a tool again that I'd use to trace all the graphics. It was just a checkbox... one that determined whether to change the units of the imported mesh into Unity units. I turned that off and everything was great. So, when these experienced users and teachers don't explain things in depth missing minor details that change everything, the learning process isn't just extended it's made a torment. I say, thanks for the information but next time please make it comprehensive. You have no idea just how discouraging it is. ruclips.net/video/P_VvEouFo8w/видео.html
I'm really late, but I just wanna add that using Translate CAN be a really good solution, if you want to have precise control over your character movement, but it is way longer to program than using Rigidbodies since you pretty much have to code the physics by yourself. For the collision detection, you can use raycasts instead of box colliders, it works great !
@@shahid-habibi I suggest watching Sebastian Lague's 2D platform controller video series if you're interested in making a character controller with raycasts. If you just want to do a simple collision test, you can refer to Unity's documentation

@@pressstart6864 The issues you were having with .AddForce() and .velocity have easy fixes. _For AddForce():_ If you want to stop at a certain speed without including drag, an if statement checking your speed vs your maximum helps. _For .velocity:_ If jumping and gravity are the only ways you plan to move vertically, rb.velocity.y as the movement vector's y should fix this. Could you maybe pin the main comment so people may be more likely to see the fixes to those issues?
I much prefer using Velocity to control my rigidbody such as: public Rigidbody2D rb2D; public float speed; //placed somewhere you have check for button press direction = Input.GetAxisRaw("Horizontal"); rb2D.velocity = new Vector2(direction * speed, rb2D.velocity.y); // this ensures that gravity still effects you even whilst moving
Thanks a lot for this very helpful composition! 👍 Two small thoughts: I think, as moveCharacter is called from FixedUpdate, you should use Time.fixedDeltaTime when calling MovePosition on the Rigidbody. Also, the magnitude of the direction vector may reach ~1.41, if two direction keys are pressed together. This should make you cover more distance with diagonal movement, which may not be ideal, but I'm currently unsure how to solve this elegantly.

To stop objects from moving through colliders when moving at a fast pace you can set the objects rigid body's collision detection from discrete to continuous. It's more performance heavy which is why it's not the default.
thank you, saved me
Sadly, it still keeps happening to me. I had to stop all movement on collision events to prevent it.
Me too, for some reason, just changing to continuous does not seem to work for me.
@@thepolyglotprogrammer have you found a fix yet?
Looking for a fix myself. I have tried everything. Continuous Dynamic on all rbs with interpolate turned on. The rb I am moving still "goes inside" the RB it's colliding with.
You know whats more fun then finding which is best for your game? Finding out that apparently none of them will work.

bro MovePosition is a life saver it is weird that after 1year of struggling i still hadn't heard of it. You are in need of this movement system 7:09
This video help me so much. On youtube people only show how to move player but they don’t explain the different between these . Thank you so much !!
8:25 u could set collision detection to discrete
8:06 if you turn the collision detection in the Rigidbody componont from "Discrete" to "Continous" this won't happen. Nice Video :D
Note that changing from discrete to continuous is much more performance intensive though, so be careful
ty buddy, you rock.
Not on translate if the speed is too high, that only applies to Velocity

//Controlling an object this way overrides physics including gravity but will still have collisions
rb.velocity = direction * speed;
//Or we can use RidigBody.movePosition;
//This may be the best option for moving a character because it works with physics & is more easilty controlled
//In this case we're only concerned with moving on the X axis so we're using Vector2 and convert this to a x
and y transformation by adding a (Vector2) before transform and don't forget the brackets
//If on the other hand you want to move the character on all axis including Z then you don't need the Vector2 variable for movement above and you also don't need to convert this code to adjust it with (Vector2) before transform
rb.MovePosition((Vector2)transform.position + (direction * speed * Time.deltaTime));

Thanks for sharing
@@pressstart6864 The issues you were having with .AddForce() and .velocity have easy fixes.
_For AddForce():_
If you want to stop at a certain speed without including drag, an if statement checking your speed vs your maximum helps.
_For .velocity:_
If jumping and gravity are the only ways you plan to move vertically, rb.velocity.y as the movement vector's y should fix this.
Could you maybe pin the main comment so people may be more likely to see the fixes to those issues?
Thank you for this! Great explanation about the different choices!
Great explanation , great animated , great example , just wow thanks so much ,
You're awesome, thank you!

This is exactly what I'm looking for! Thank you so much!
got a subscription only because of this great explanation !!
thanks a lot buddy, finally!
wow , amazing! well explained ! thanks man keep up the good work!
I much prefer using Velocity to control my rigidbody such as:
public Rigidbody2D rb2D;
public float speed;
//placed somewhere you have check for button press
direction = Input.GetAxisRaw("Horizontal");
rb2D.velocity = new Vector2(direction * speed, rb2D.velocity.y); // this ensures that gravity still effects you even whilst moving
I love your tutorial man! Very useful information
Thank you!
Translate like the wise say, is when you need to teleport an object through mediums. Nice video 👍🏼
bravo explaination iz off the chart i humbly thank You for Making video as beginner it's really helpful!!
Thanks a lot for this very helpful composition! 👍
Two small thoughts:
I think, as moveCharacter is called from FixedUpdate, you should use Time.fixedDeltaTime when calling MovePosition on the Rigidbody. Also, the magnitude of the direction vector may reach ~1.41, if two direction keys are pressed together. This should make you cover more distance with diagonal movement, which may not be ideal, but I'm currently unsure how to solve this elegantly.
I believe normalizing (.normalized) the "movement" vector will solve this diagonal speed issue.
Nice and cool and very comprehensive thanks dude
Thanks for stopping by!
awesome content bhrastar(farcry primal).
Dude, this video saved me a lot of time, thank u
