[2D] Bug ground collision

It helps if you post some code.

I'd check the colliders. But without any code it's really hard to give you any help.

Here's my only script, for my caracter :

 using UnityEngine;
 using System.Collections;
 
 public class PlayerScript : $$anonymous$$onoBehaviour {
 
  public Vector2 speed = new Vector2(0,0);
  public Vector2 movement = new Vector2(0, 0);
 
  void Update()
  {
   float inputX = Input.GetAxis("Horizontal");
   bool jump = Input.GetButtonDown("Jump");
   speed.x = inputX * 10;
   if (jump)
     speed.y = 10;
   else 
     speed.y = rigidbody2D.velocity.y;
   movement = new Vector2(speed.x, speed.y);
   
  }
 
  void FixedUpdate()
  {
   rigidbody2D.velocity = movement;
  }
 
 }

I thought the problem didn't come from this, that's why I didn't post it.

I'm not sure if this works for 2D physics or just 3D, but perhaps you could test it. I think Unity still need to add an equivalent setting to 2D. Try changing $$anonymous$$in Penetration for Penalty to 0 in Edit > Project Settings > Physics.

I think I found the problem! $$anonymous$$y caracter only had a box collider. I added a circle colider for his feet, and it works!

Thanks for all! (What I have to do to make my question "Solved"?)
