//public UISlider slider;
void Start(){
	UpdateSubHealth();
}

public void OnTriggerEnter (Collider collider){
	if(collider.gameObject.name.ToString() == "Torus001"){
		_playerHealth-=deduction;
		Debug.Log("Hit by Colliders " + collider.gameObject);
		RING.sliderValue =0.10f;

Depending on your current setup I think the problem may be that before OnCollisionEnter can be called again, the two collider have to move apart first. If this is the case you can

  • either make sure that after the first hit the colliders are divided (not overlapping) before you want to apply damage again.

  • or you can use the OnCollisionStay() function, which will apply Damage while Objects are touching each other. To avoid apllying damage every Frame you can set the function up with a coroutine like this:

    bool touched;
    float timeToTouchAgain = 0.5f; // 0.5 seconds

     void OnCollisionStay(Collision collision)
 {
     if(collider.gameObject.name.ToString() == "Torus001")
     {
         if (!touched)
         {
              StartCoroutine(MyTouch());
              // Do you stuff, aplly damage
         }
     }
 
 }
 
 Ienumerator MyTouch()
 {
     touched = true;
     yield return new WaitForSeconds(timeToTouchAgain);
     touched = false;
 }

It should work. If you have any questions left, just ask :slight_smile:
