Question by Brokenarrow · Jun 13, 2013 at 12:07 PM · triggergetcomponentbooleantag

Weird issue with boolean

Im trying to check, from and external script in a parent, when a trigger collider leaves a surface. I do this with a boolean, but for some reason it always returns false (even when manually set to true) What am I missing?

Parent Script:

         GameObject bottom = GameObject.FindWithTag("Bottom1");
         VehicleBottom other = bottom.GetComponent<VehicleBottom>();
         
         if (bottom == null)
             Debug.Log("Vehicle bottom is not found");
         
         if (other.touchingGround == false)
             Debug.Log ("Not Touching Ground");
         
         if (other.touchingGround == true)
             Debug.Log ("Touching Ground");

Child Script:

     public bool touchingGround = true;
     
         
     void OnTriggerExit(Collider other){
         
         
         touchingGround = false;
         Debug.Log("Vehicle has lost contact with ground");
         }

Because when you are not colliding you are setting it to false:

 OnTriggerExit(Collider other)
 {
 touchingGround = false;
 }

thats why it's always false.

indeed.there is no point in the code you pasted where you set touchingGround to true :D

...other than the declaration

But its supposed to be false when I'm not colliding, I just don't understand why it doesn't turn true when it is colliding(which is most of the time)

where is your :

    OnTriggerEnter(Collider other)
     {
     touchingGround = true;
     }

I figured it out,I assumed it would go automatically back to true when it started colliding again. A additional OntriggerEnter did the trick. Thanks for pointing out my logical fallacy.
