TURN GRAVITY ON!

Lads,

I'm using projectiles to destroy chunks out of a wall. Once 100 chunks have been destroyed I'd like to turn gravity 'on' so the wall collapses. Having a hard time getting 'er done. Here's my script. Any thoughts for a scripting noob?

 function OnCollisionEnter(collision : Collision) 
 {
     if (collision.gameObject.tag == "missile_1")
       {
         Destroy (gameObject);
         //Instantiate (smokePrefab, transform.position, transform.rotation);
         //Instantiate (Sphere, transform.position, transform.rotation);
         objectDestroyed++ ;
         print (objectDestroyed);
 
 
     if( objectDestroyed >= 100)
 {
          gameObject.rigidBody.useGravity = true;
 }
 }

Thanks,

Stef

I'm going to assume you have this script on each of your "wall blocks" that you want destroyed. If that's the case, the real problem is that you have a different objectDestroyed variable in each script. There's no cumulative counter.

You need to have a script that keeps track of that sort of thing on an object that isn't going to be destroyed. (invisible gameobject would be fine). Each time a block gets destroyed, have it modify the objectDestroyed variable in that "master" script. Then check against that variable in your Update function to determine when to flip on gravity.
