Question by Rob64j · Mar 22, 2019 at 12:12 PM · 2d-platformerontriggerenterontriggerexit

Pressure Switch Issues

Hi all, I'm hoping someone can point me in the right direction with this issue I'm having. In a nutshell; I have a basic 2D platformer containing a pressure switch which animates down with OnTriggerEnter and animates back up with OnTriggerExit - all fine to this point, however if the player returns to the switch OnTriggerEnter/Exit are being called continuously one after another causing the switch to bounce up and down... I can't figure out where I'm going wrong with this and I don't necessarily want the solution straight up (I would rather learn properly) but would love some pointers if anyone has any advice?

Thanks in advance and please see code below;

 Animator animator;
 Animator playerAnim;
 private bool onSwitch = false;
 private bool playerTall = false;


 private void Start()
 {
     animator = GetComponent<Animator>();
     playerAnim = FindObjectOfType<Player>().GetComponent<Animator>();
 }

 void OnTriggerEnter2D(Collider2D other)
 {

     if (playerTall == false && other.tag == ("Player") && onSwitch == false)
     {
         //Debug.Log("GoTall");
         onSwitch = true;
         playerAnim.SetTrigger("GoTall");
         animator.SetTrigger("Down");
         playerTall = true;
     }
     else if (playerTall == true && other.tag == ("Player") && onSwitch == false)
     {
         //Debug.Log("GoSquare");
         onSwitch = true;
         playerAnim.SetTrigger("GoSquare");
         animator.SetTrigger("Down");
         playerTall = false;
     }

 }

 void OnTriggerExit2D(Collider2D other)
 {
     //Debug.Log("ExitCollision");
     animator.SetTrigger("Up");
     onSwitch = false;
 }

}
