I am very new to unity and I am getting this error.
I really have no clue what to do to fix it so I hope someone can help me.
UnityEngine.Component' does not contain a definition for velocity' and no extension methodvelocity' of type `UnityEngine.Component' could be found. Are you missing an assembly reference?'

I am a beginner and I have copy-pasted shamelessly a 2Dcontroller script, now the problem is that the movement speed of the character is affected by the crouching speed all the time, so what I want it to do is for the character to be affected only when the button is pressed down.
The following is the copy-paste.

Are you using the Move method in another script?
If you're using that somewhere else and are attempting to assign to something using its result, it will result in that error.
Edit: Might also be the call to OverlapCircle(). It returns a Collider2D, but you're treating it as a boolean value by having it in an if check.
Try using it like:
if (Physics2D.OverlapCircle(m_CeilingCheck.position, k_CeilingRadius, m_WhatIsGround) != null)
I've been following Brackeys tutorials to make a 2D game and right now I'm on animation. The animation plays he attacks, the sprite flips both directions, etc.. but still stuck in the same spot. I've watched and rewatched the tutorial and can't figure it out.
Before adding animation everything worked perfectly. He moved across the screen, he jumped, etc.. So i know that him not moving is directly tied to trying to animating
This is my playermovement script I made from following his tutorial.
public class playermovement : MonoBehaviour
{
public CharacterController2D controller;
public Animator animator;
public float runSpeed = 40f;
float horizontalMove = 0f;
bool jump = false;
bool Attack = false;
void Update()
{
horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;
animator.SetFloat("Speed", Mathf.Abs(horizontalMove));
if (Input.GetButtonDown("Jump"))
{
jump = true;
animator.SetBool("IsJumping", true);
}
if (Input.GetKeyDown(KeyCode.Mouse0))
{
animator.SetBool("Attack", true);
Attack = false;
}
}
public void OnLanding ()
{
animator.SetBool("IsJumping", false);
}
private void FixedUpdate()
{
controller.Move(horizontalMove * Time.fixedDeltaTime, false, jump);
jump = false;

It's probably a bit late to help the OP now, but I had exactly the same issue today and finally figured it out.
I was scaling the main object for some of my animations. To fix it I went in and removed any scaling of the main container object and instead scaled the internal objects individually and now the flipping works.
Clearly the animation scaling interferes with the controller flip scaling.
Try This Code but make shure you Character has a 2DRigidbody and a 2DBoxcollider and watch out that the script has the name "Character2DController"
I hope it will help you ;)

You may check the values from horizontalMove while debugging or add a Debug.Log statement to check its value while testing, just to make sure that the value is what is expected.
Also ensure that controller was assigned.
I'm trying to make a spring wall in my 2d platformer. However every way I've tried to move my character (addforce, transform.translate and even tried using the bouncy naterial) teleports my character rather then moving it. This doesn't happen with my controller script. I suspect something in my script is causing this interaction but I'm not sure exactly what. Here is my controller script. Any suggestions would be greatly appreciated :))

I have a little problem with my player control script (C#) in the unity enigne. I worked out the following script with the basic movement of the player. The problem is that the player can enter the jump statement (the debug log printed it out)
Debug Log
but it will not work. The character is still on the ground.
The jump function will be enabled when the player is on the ground (grounded) and did not a double jump.
So my question is are there any "code mistakes" or maybe some configuration problems which I do not see?
Thank you for your help in advance!

Just guessing here, but maybe Vector3.up does not work for 2D physics? I'm not really into 2D, but you could try
playerRigidbody.AddForce(transform.up * jumpHeight);
instead.
Also, have you tried different values for jumpHeight? 5 might be way to small depending on the mass you set for your rigidbody.
And make sure you haven't restricted any axes in the inspector.
// Note: If you want the object to move in a reliable predictable way but still allow physics interactions, use MovePosition (set the object to kinematic if you want it to be unaffected by physics but still be able to affect other things, and uncheck kinematic if you want both objects to be able to be acted on by physics.
If you want to move your object but let physics handle the finer details, add a force.
playerRigidbody.rigidbody2D.AddForce(Vector3.up * 10 * Time.deltaTime);
use Vector.up, Vector.down, vector.right, Vectore.left along with time.deltaTime to have smooth movement along the frame.
