public class CollisionHandler : MonoBehaviour
{
    private float _initialY;
    private Quaternion _preRotation;

    private void OnCollisionEnter(Collision collision) {
        if(collision.gameObject.transform.CompareTag("Wall")){
            //if the object has the tag of Wall
            _preRotation = gameObject.transform.rotation;
            _initialY = gameObject.transform.position.y;

            //set the player's position to of the contact point of collision
            gameObject.transform.position = collision.contacts[0].point;
            gameObject.transform.position = new Vector3(gameObject.transform.position.x, _initialY, gameObject.transform.position.z);
        }
    }

    private void OnCollisionExit(Collision collision) {
        if(collision.gameObject.transform.CompareTag("Wall")){
            //resetting the player's rotation to the value before collision
            gameObject.transform.rotation = _preRotation;
        }
    }
}

Description:

• Awake():
• OnCollisionEnter(Collision collision):
  • If the colliding object has the tag of Wall,
  • save the initial rotation and y poition of the player to _preRotation and _initialY respectively
  • set the player's y position to _initialY
• OnCollisionExit(Collision collision):
  • if the colliding object has the tag of Wall when exiting, set the player's rotation to _preRotation

Deletion of script

Reasoning

Script was causing jittering when player initially collides with the walls.

Script has been deleted from source codes
