![2D Movement [Rigidbody vs Transform] Mastery Tutorial Unity (2021 edition)](/img/n.gif)
as a complete beginner. I did not understand this video very well but after a few weeks of messing around in unity and i can finally understand what is in this video
Yeah what in the world is going on here ._.
@@Externium :)
Fun Fact, if u look at some of the areas on the script window you will notice that the language is in german
yes I found out
Jaja das hast du gut gesehen
@@Luigi_Guy21 shut up
This tutorial was very helpful by showing the whole process of making the script that made the character move, Thank you!
This is probably the best programming tutorial I've ever seen. Extremely easy and to the point. And for someone who's done this multiple times in the past, but simply don't want to type it all out again, linking the source code makes everything so much easier.
Mee too, i give it 100/100!
God tier tutorial, finally something that is short and works great instead of an 18 min video that bugs out!
Fr fr
If your character is moving left and right but doesn't jump after finishing tutorial you might have missed the point where he moves Ground Check object early in the video closer to players feet and ground. 🎉
Been working on this issue for literally weeks, bless you wise internet stranger!
@@joshpreston4957 Glad it helped you, because it took me a while as well.

OMG thank you god it's been 3 hours just sitting here what went wrong
The video would be a lot better if you'd actually explain WHY you do certain things instead of just telling us THAT you're doing it. Could have just provided the source code without a video at this point (for the most parts).
this is the biggest mistake online unity tutorials make. they never explain why things work the way they do.
Exactly!
I agree
Whomp
Whomp jk I agree
I saw this comment before seeing the entirety of the video and I fought "what do they mean everything here is self explanatory." now the video is finished I entirely understand what you mean.
Very nice video, easy to follow! I just feel like you go over some stuff without explanation, which can make it difficult to understand why we do what we do, like Collision Detection, Sleeping mode and interpolate. I have no idea what it means, but I just do as you say and it works :) Great video overall tho! Big props!
If anyone's wondering why they can't jump, the "jump" key is set to space by default. To change it to something else, here's the code.
if (Input.GetKeyDown(KeyCode.UpArrow) && IsGrounded())
{
rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
}
if (Input.GetKeyUp(KeyCode.UpArrow) && rb.velocity.y > 0f)
{
rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
}
It doesn’t work even if I press space though 🫤
@@BIGBLACKHAWK123You definitely done something wrong then. I had the same issue until I linked all the objects. Try watching the video multiple times to understand what is actually going on rather than saying it doesn't work. :)
Check if your Ground Check is actually "grounded". If you create it first, it places the object in the middle of the player, this causes it to never touch ground. And results in failing the ground check and blocking you from jumping. Move it lower on the player.@@BIGBLACKHAWK123
omg thank you I haven't knew that.
that was the problem, thanks!@@zanahtile6276

After 3 hours of attempting to figure out why I wasn't able to jump, I found that you need to assign your keys to the "Jump" input in input settings. While horizontal is pre-set, jump is left blank and this left me absolutely baffled until I figured it out.
HELP
PLEASE
that ground checking system is simplistic brilliance, I was stuck for hours trying to think of that and in this moment i am hoping that you're a wizard and it's not just some super simplistic thing everyone has been doing for ages except me
Haha, I'm definitely not a wizard.
@@bendux thats exactly what a wizard would say
For everyone that struggles with the player falling through the ground,
Make sure that your ground is not imported from a file but made in the 'Hierarchy'. (if its not imported its grey in the hierarchy otherwise its blue)
Good luck!
Thank you for sharing!
@@bendux np!
I did this and it still doesn't work
@@wogs2k Join our Discord server, and let's solve your problem together!
@@wogs2k Also make sure that on both the BoxCollider2D of the player and the platforms, the box "Is Trigger" is not ticked
Thank you! I spent over 10 hours trying to do this and you showed me how to in 5 minutes, it's perfect! Just had to be a little careful as you didn't say out loud everything you were saying, but it's otherwise an amazing video, and still up to date! Thanks again!
This is the only tutorial where I get good physics for the player, thanks so much :)
Thanks for the awesome 2D movement in Unity tutorial! Super helpful! 👍
Amazing, I was able to figure it out from the video with only like 2 errors that were extremely easy to solve. Superb video!
Now I just gotta figure out how to make magic fist attacks with effects, determine a combo system, and design and figure out how to link side profiles to the player sprite with walking animations.
I'm glad I could help. Good luck!
HOW THIS FEELS IMPOSSIBLE
This is an amazing tutorial! Thank you so much, I really loved this!
Beautiful. Kinda funny I thought the jump didn't work cause i was pressing w or the up button, but then i realized it was space
I struggled with the built-in input manager. No matter what I did it seemed to apply some form of deceleration/acceleration when I moved the player. So instead, I did something similar to you in this video and that fixed it. Nice and snappy movement, just as you'd expect in a 2D game.
Here is the script for those who need it
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
private float horizontal;
private float speed = 0f;
private float jumpingPower = 16f;
private bool isFacingRight = true;
[SerializeField] private Rigidbody2D rb;
[SerializeField] private Transform groundCheck;
[SerializeField] private LayerMask groundLayer;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
horizontal = Input.GetAxisRaw("Horizontal");
if (Input.GetButtonDown("Jump") && IsGrounded())
{
rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
}
if (Input.GetButtonUp("Jump") && rb.velocity.y > 0f)
{
rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
}
Flip();
}
private void FixedUpdate()
{
rb.velocity = new Vector2(horizontal * speed, rb.velocity.y);
}
private bool IsGrounded()
{
return Physics2D.OverlapCircle(groundCheck.position, 0.2f, groundLayer);
}
private void Flip()
{
if ((isFacingRight && horizontal < 0f) || (!isFacingRight && horizontal > 0f))
{
isFacingRight = !isFacingRight;
Vector3 localScale = transform.localScale;
localScale.x *= -1f;
transform.localScale = localScale;
}
}
}
yo, my serialized fields arent showing up in my unity project and i was wondering if you could help
@@wizard7317 did u save the script in vs before going back to unity?
this script gives me no movements :c i turn left and right but cannot move
@@furyz0339 you have to change the speed in vscode to 8 (in the comment it is set to 0)
thank youuu @@noona7701
Thanks for this awesome smooth moving video, but can you do 2d enemy ui or shooting?
I've added it to my list. Thank you for the suggestion!
@@bendux YEsssssss exactly what i wanted thanks(i want to make a shooter game cuz im new)
Very nice tutorial, one thing that I noticed, or if I may have missed, however, is that when I go to jump, the player doesn't have a limit to how many times they can jump in the air. Is there something that I would need to type in to fix that? I noticed that wasn't established in the video, but if anyone has an idea of how to put that in it would mean a lot. I'm a beginner at coding myself, so I'm not too big on this kind of stuff.
Would you like to show me your code on Discord?
@@bendux Oh, thank you. But I actually managed to figure it out from another source. I appreciate the offer though. And what all you had shown here in the video.
@@cheezeburger7716 I'm glad you were able to fix it.
@@cheezeburger7716 can you tell me how you fixed it? i want to fix it too

This is incredible, I coded for a while but couldn't get past the basics will watch more
I like people that actually put code in the despcription :)
Hey! Just wondering, if we want to animate, what boolean or Float should i use for the transition?
Yeah bro I was about to ask tha’
Thank you, this was my first time using C# and this really helped me!
Yo, great work here 👏.
Don't ever stop and you will be the new brackeys
Отлично. Я делал подобный урок от другого автора. Персонаж дёргался. А тут всё движется плавно и код выполнен здорово компактно. Настройки физического тела показал как настроить . Спасибо за урок
Love it, I personally like adding a Lerp function for some smoother acceleration and floatier physics, but that’s just my prefrance
When you'll make a video about how do object follow the player (like Mario, luigi and paper mario in Mario and luigi paper jam), i'll be very happy. Great video, i resolved all my problem with 2d player movement
I've added it to my list. Thank you for the suggestion!
Thanks for the great video. I wanted to ask about one thing I'm quite confused about. It seems that you didn't program any horizontal movement keys that need to be pressed down to move, yet you still are able to move. The only key you referenced in the script was jump. How is that possible?
Edit > Project Settings > Input Manager
@@bendux Thanks a lot!
@@benduxwhat do i do in inputmanager
My face when i don’t understand 99.9999% of the code 5:33
I definitely want to make more beginner-friendly videos in the future.
@bendux THIS IS THE BEST TUTORIAL EVER!!! I CAN MOVE AND JUMP btw you just earned a sub
Thank you!
@@bendux no problem
Man thx, did know / thought you cloud just change the velocity in script. Makes everything soooo much easyer and I dont have to fiddle around with AddForce etc. Thank you again man.
Hey! Quick question, how exactly would i make the run/walk a method if possible? Just so that I have a place to add in my audio, dust particles, etc. Cuz I'm new to this whole thing haha
The answer to your question goes beyond the scope of a UA-cam comment, but I'd still like to help you. Join our Discord server, and let's solve your problem together!
hey, great video, everything is working fine but im jumping WAY too high, how can i decrease the jump power?
Decrease the jumping power at the top of the script.
you can change the value in the script from "private float jumpingPower" to "public float jumpingPower" and this will allow you to directly adjust the power in unity rather than opening the script! :D good luck!
@@bendux didnt do anything, is there another fix?
@@gumball5372 Increase the gravity scale of your player's Rigidbody 2D component.
@@bendux i found the fix, i tried this but it didnt work. I have no clue what the problem was but it works now
Very nice and simple.
Hippity Hoppity Your Code Is Now My Property - "Apleker"
thanks a lot bro i went to many videos just for this even brackys tutorial didnt work
and i tried this love you bro
Brackys tutorial is where all the souls go😂😂
@@iAmStanee its just really outdated
I have a problem with the movement, I added the no friction material to two objects, but after they collide, they start getting stuck on the floor, even after moving and jumping
The floor uses tilemap colliders, if that helps
Edit: probably solved, I used a composite collider too
Add a Composite Collider 2D component to your tilemap.
@@bendux thank you so much
You explained this well. also it works. thanks!
Your tutorials are the best i gona make a game with those
I want my cube when the cube is jumping while moving to the right, the cube will jump and rotate 90 degrees to the right as well and there should be a kind of animation and not just instantly changed to 90 degrees.
Edit: just like in Geometry Dash
I could use some help regarding slopes. Much appreciated for the easy to follow tutorials!
i can't jump
neither, left and right works just no jump
have any of you found a solution yet? It looks like it's a common problem.
yes, my problem might be different to yours but I solved it by moving the 'ground check' to the position of the bottom of the player as I forgot to move it as said at 1:17@@wayvoedorado71
@@finngrainger349 that wasn't my problem, but you encouraged me to look into it and my problem was that I forgot to change the platform layer to ground so thank you
You probably skipped one or two important steps in the tutorial.
The old input system is not worth using anymore.
Yes it is stfu
Literaly the most difficult to understand tutorial
This tutorial was to easy to be true like how does he do so much with so less code. And not to mention its so easy to read.
bro is definitely not a beginner, Very helpful video and thank you
underrated channel, hopefully unity notices you someday
very simple yet satisfying and fun movement, straight to the point video, simply one of best on youtbe
Hey if you dont want your player to be stuck on walls when applying the horizontal force, use the CharacterController component instead!
Create a Physics Material 2D, set the friction to zero, and add it to your player's Rigidbody 2D component.
Note: YOU NEED TO CREATE A BOX COLLIDER 2D ON TILES to stop character from falling as well
I have watched tons of tutorials, best one yet
my player wont stop falling through the damn ground
If you want two game objects to collide with each other, both game objects require a collider.
bro add a box collider, like you did with the player
You literally saved me by making this video, earned a sub
Btw if u are having problems with the rub, ground check and ground layer not appearing then just copy and paste the source code in the description because I had followed all the steps and it wasn’t working but when I copied it the errors got fixed
The source code on GitHub is the same as in the video.
Thanks, I was just looking for this.
can we just appreciate that he is still responding to comments! you're awesome!
Nice tutorial, the SpriteRenderer Component can also be used, just get the flipX (bool) attribute, instead of using localScale -1.
Thanks for the tutorial! I'm a beginner and this helps alot!
Can anybody help, I cant do anything upon competing it, it just says horizontal axis not set up? is it something with velocity being obsolete?
if you get ur player to an edge of a platform it won't be able to jump bc the ground check under the player is in the middle and doesn't cover the entire size
You can adjust the radius of the ground check.
This helped me alot and I even somehow got my player to infinite jump like flappy bird. Definitally a win
If you want to get rid of this behavior in the future, make sure that your player and the ground are not on the same layer.
@@bendux Thx man, oh and btw I subbed to you for your awesome Unity tips!!
@@KrixerVR I appreciate it. Thank you!
thank you so much ,without you i would still be stuck in how to move it .
you've got a sub
thank you so much, sir bendux! it help quite significantly
Always good videos! 1k subs let's go!
For those wondering why you can't jump remember to change the layer of your platforms to ground, had me confused for a few minutes

I dont have rb, ground check and ground layer after i made the code 4:57
Did you save the script?
Thank you bendux. The video helped me so much.
Its better to use a trigger colider instead of an empty object to check for grounded so you can change the width
You can adjust the radius of the ground check.
Hey umm what coding software are you using?:)
I use Visual Studio.
Thank you so much, this tutorial was very helpful!
I'm sorry but, I though I searched up "simple 2d Unity movement guid", I was was expected much easier.
Simple, quick & elegant. Nice!
this is perfect, with a few google searches.(if you dont understand stuff like uhh serialize field and are VERY new to programming in c# but kinda know python.(me))
what a gentle jazzy ambient

Same feels bad.
Do you happen to have another class with the same name in your project?
when i attach the script component to the player, i am given the error:
"The associated script cannot be loaded.
please fix any compile errors and assign a valid script."
but vscode doesn't show any compiler errors, what do i do?
Make sure that the class at the top of the script has the same name as the script itself.
@@bendux This fixed it! Thank you!
Good video but i have a problem, i cant jump can i know how do i fix it?

I have a bug where it doesnt delete the versions of itself left behind after moving
It probably has something to do with your camera.
for some reason when i press play i get stuck to the ground even tho i added 0 friction and i cant move can u help me with that??
If you have a tilemap in your scene, add a Composite Collider 2D component to it.
I've spent afew hours trying to find one that worked... a 5 minute simple video, that is simple and easy to understand; compared to a 30 minute jumbled video that doesnt even work... That red subscribe button is calling!! Thank you so much
Okay, normally I try fixing things myself before asking, but when I saw this I knew something was wrong.
Whenever I opened the movement script like he did at 4:54 ; but when I did, the options never showed up, instead, I got an error reading, "The associated script can not be loaded. Please fix any compile errors and assign a valid script."
I'm new to game design, while my only other project was a website for games I found for my friends to play in our classes. ( I hope that explains why my error might make me sound like an idiot for not knowing how to fix it. )
Make sure that the class at the top of the script has the same name as the script itself.
Glad I got the fix so early. You're a lifesaver.
Now to figure out how to make the player have physics with tiles. ( Moving across tiles )
@@AidenUPVR Add a Tilemap Collider 2D component and a Composite Collider 2D component to your tilemap.
@@bendux I got that. I'm proud of it. Even though its just a forest green box, with a few places to stand on, I'm happy with it.
I'm trying to make a game for my friends to play.
I also have one more thing I want to change. In the script somewhere, there's a feature that lets the player jump infinitely. Since I'm going to be making a parkour puzzle game, I really don't need players to double-jump their way to space lol.
2:24 can someone explain why he used FixedUpdate here and not normal Update?
i changed the input of horizontal and forgot to set Jumpingpower and MoveSpeed and it fixed all thank you
edit: changed input back again and it worked flawless dont know what my problem was :)
and didnt know that GetAxisRaw is refered to the a and d button
help me my guy goes left and right but he turns immediatly, example: im going right with "d" but when i pressed "a" he teleports to back and turns to left please help
It's hard to tell what's going on without seeing your script.
Danke, hat problemlos geklappt!
Unity is so cool and nice video man :]
The jumping part isnt working for me because somehow the groundcheck isnt sticking to the character..can anybody explain what to do
The ground check must be a child of the player.
I'm at 4:55 and the script has no spaces for me to drag in the references. Some of the code I was writing didn't light up like yours either, so that may have something to do with it. Would you know a fix?
Make sure that the script is saved and doesn't contain any errors.
@@bendux thanks for the reply! I finally found it out thanks to a very small video I found after hours of searching😂 I had to change the “external script editor” to Visual Studio, as it was set to “file extension” by default for some reason.
