How to stop player jiggle when running in to a object 2d

[anon20000101]

Hi!
Im having a problem with my character controller, When i walk in to a object it jiggle in to the object and back really fast. I couldent find a tutorial first and when i finally did it dident work. I am using a rigidbody and a capsual collider, The rigidbody is set to interpolet and continues.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    public float movementSpeed;
    public float jumpForce;
    public float fallSpeed;
    private bool Grounded;
    Vector2 gravity;
    public Rigidbody2D rb;
    // Start is called before the first frame update
    void Start()
    {
        gravity = new Vector2(0, -Physics2D.gravity.y);
    }

    // Update is called once per frame
    void Update()
    {
        JumpFunction();
      
    }

    public void FixedUpdate()
    {
        var movement = Input.GetAxis("Horizontal");
        transform.position += new Vector3(movement, 0, 0) * movementSpeed * Time.deltaTime;
    }
   
    void JumpFunction()
    {
        if(Input.GetKeyDown(KeyCode.Space) && Grounded == true)
        {
            rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
        }
        if(rb.velocity.y < 0)
        {
            rb.velocity -= gravity * fallSpeed * Time.deltaTime;
        }
    }
   
   
    void OnCollisionEnter2D(Collision2D other)
    {
        if(other.gameObject.CompareTag("Ground"))
        {
            Grounded = true;
           
        }
    }

    void OnCollisionExit2D(Collision2D other)
    {
        if(other.gameObject.CompareTag("Ground"))
        {
            Grounded = false;
        }
    }
}

Moving via transform.position += means you are teleporting your player around and bypassing/ignoring the physics engine entirely. The solution is to move via your Rigidbody2D instead.

Okay so i should use addforce but can i use horizontal or do i need to manuely make the keybinds?

With Physics (or Physics2D), never manipulate the Transform directly. If you manipulate the Transform directly, you are bypassing the physics system and you can reasonably expect glitching and missed collisions and other physics mayhem.

Always use the .MovePosition() and .MoveRotation() methods on the Rigidbody (or Rigidbody2D) instance in order to move or rotate things. Doing this keeps the physics system informed about what is going on.

Collisions in high speed without unity physic / rigidbody

You say you're not using 2D physics but you're using queries therefore obviously colliders. This IS using 2D physics therefore you need to use it correctly so here are some basic rules: Don't ever modify the Transform if using 2D physics components If you want a 2D Collider to move then add a Rigidbody2D and use its API to move it; many ways to do this. Rigidbody2D don't make it "unresponsive". If you want explicit control then set the body-type to Kinematic; it's what it's for. When you qu…

OnCollisionEnter2D not being called

That’s not related to body-type. You should never drive via the Transform. The main thing to understand here is that the Rigidbody2D role is to write to the Transform after the physics simulation, not the other way around. It acts as a proxy to the Transform because you want physics behaviour. Does “it work” if you write to the Transform and force the Rigidbody2D to read from the Transform? Yes! It works like that because otherwise it’d be reported as a bug and so we’re forced to “support” it.…

With a wheel collider, use the motor or brake torque to effect motion.

Do not mix setting position with AddForce or setting velocity.

That’s like me telling you “Run that way” but then forcing you to go to a spot in the room, and then pushing on your arm in another direction. It’s three different things. Pick one.

Either:

• add force

OR

• set velocity

OR

• compute position and call MovePosition
