Making a Collider only collide with objects that don't share the same material color. (89645)

Questions & Answers

Without messing with physics layers(as I’d need different ones for every possible color) what is the best way to do this? I don’t want to enable/disable the collider based on what is touching it as if two objects hit it at the same it would cause problems.

Any suggestions appreciated, preferably in JS.

EDIT:

I have the following:

function OnCollisionExit (thingHit : Collision)
{
if(thingHit.gameObject.renderer.material.color == renderer.material.color)
Physics.IgnoreCollision(collider, thingHit.collider, false);

if(thingHit.gameObject == player)
manager.GetComponent(ColourChangeScript).switcherE nabled = true;
}

function OnCollisionEnter (thingHit : Collision)
{

if(thingHit.gameObject.renderer.material.color == renderer.material.color)
Physics.IgnoreCollision(gameObject.collider, thingHit.collider, true);

if(thingHit.gameObject == player)
manager.GetComponent(ColourChangeScript).switcherE nabled = false;
}

It isn’t ignoring the collisions at all. Any ideas?

Try this:

function OnCollisionEnter(col:Collision){
   StartCoroutine(disableCollisions(col.collider, this.collider, 2));
}
 
function disableCollisions(c1:Collider ,c2:Collider, seconds:double)
{
  Physics.IgnoreCollision(c1, c2, true);
  yield WaitForSeconds (seconds);
  Physics.IgnoreCollision(c1, c2, false);
}
