Dumb Collision Question

Unity Engine
1

So I have an empty object with a capsule collider, marked as a trigger. I want to make it so it will output the tags of the game objects, that collide with it, but I don’t know why, it won’t work.

function OnTriggerExit(collision : Collider){ 
print(collider.transform.tag);
}

function OnTriggerStay(collision : Collider){ 
print(collider.transform.tag);
}

Sorry for that dumb question, I sometimes get stuck with really dumb things and can’t get them to work.

Are you sure you have colliders on the other game objects, and that they’re configured correctly to send trigger events?

Well of course, I can see the capsule collider in the editor and also Is Trigger is checked. Pretty trange, huh? I need to check if the collider is toching something…anything.

double check the collision matrix here:

also, unity 3.0 introduce layer based collisions:

Yes, I have read those (thanks though). I don’t know what’s happening. For example if I rub the object aganst a wall (the object is placed at the RaycastHit.point of a raycast, taht goes from the camera) it will output the wall’s tag, but not always. I can’t say the same things for rigidbodies though, it won’t count them. The layer that this object is in collides with everything.

what is the trigger object exactly. Try making it a kinematic rigind body trigger collider. Or post a full example project.

Yes, I added a rigidbody and it worked. Thank you!
