BUG? Player colliding when should not

my player is walking over a collider, but when that ends, the player don't fall, just still going straight like if it was over a collider, but if I press to jump it falls down. How can I fix it?

The player has a rigidbody.

jump code:

Code (CSharp):

1. if (ut.Runtime.Input.getMouseButtonDown(0)) {
2.                                     this.playClip("jumpAudio");
3.                                     const physicsConfig = this.world.getConfigData(ut.Physics2D.Physics2DConfig);
4.                                     physicsConfig.gravity = new Vector2(0, -30);
5.                                     this.world.setConfigData(physicsConfig);
6.                                     let vel = new ut.Physics2D.SetVelocity2D;
7.                                     vel.velocity = new Vector2(0,0);
8.                                     let impulse = new ut.Physics2D.AddImpulse2D;
9.                                     impulse.impulse = new Vector2(0, player.jumpForce);
10.                                     this.world.addComponentData(entity, vel);
11.                                     this.world.addComponentData(entity, impulse);
12.                                 }

 

It might be because your changing the pivot of your collider.

Iv noticed you have to move the collider around with the transform and leave its pivot at (0.5, 0.5)
