Bug Why does my character glitch when it lands

For some reason, my player character glitches when it hits the ground(containing a BoxCollider2D and a "Ground" tag).

By 'glitch' I mean:

• When it spawns in the air it de-spawns when colliding with the ground, spawns in the air again then the cycle repeats
• When spawns on the ground, the animations work, but it doesn't move at all.

Player RigidBody2D details and Script values:


Player Code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;

5. public class Player : MonoBehaviour

30.         rb.velocity = new Vector2(xMov * speed, rb.velocity.y);
31.         if ((facingRight && xMov < 0) || (!facingRight && xMov > 0))
32.         {
33.             Flip();
34.         }
35.     }
36.  
37.     void Update()

64.         transform.localScale = scaler;
65.     }
66.  
67.     void OnCollisionEnter2D(Collision2D collider)
68.     {

Is your ground or an object on your ground tagged as "Spikes"? Do you have any other scripts involved, such as on the ground?

One error I'm noting in your code is that your OnCollisionExit2D does not have the proper method signature. It is supposed to have a Collision2D parameter (much like OnCollisionEnter2D). Without that parameter, Unity will not call your OnCollistionExit2D. This may explain some of your animation issues.

 

There is a GameObject on the ground tagged as "Spikes". I've tried adding a parameter to the OnCollisionExit2D, but sadly nothing changed.

 

Doesn't your code destroy your player if it touches the spikes? Is it touching the spikes?

 

No, I placed the player next to the spikes so it collides with the ground first.
