Question

Well im going to be straightfoward here, this is my code

var collisionObject : Transform;


function OnCollisionEnter(collision : Collision)              //This function tests the collision and plays a sound
{
if (!audio.isPlaying && collision.gameObject == collisionObject)
{
audio.Play();
print("Play");
}
}

The "collisionObject" is the FPC and yes it has a rigidbody, the object the script is assigned to is a collision box with a Audio thing attached

I have no idea why it wont play....

Thanks Myhijim

So, this script is on a collider w/rigidbody and should be hit by the player, which uses a characterController?

CharControllers don't trigger OnCollisionEnter when they hit things. They don't use physics to move, which is where collisions happen. To test, add Debug.Log("hit by" + collision.transform.name); as the 1st line. You can verify it isn't the math -- there's just no collision at all.

Instead need to use OnCharContHit. There are a bunch of threads here on that, and hacks that don't really work (like adding a dummy isKinematic collider in front, which tends to just block the player's movement.)

Thanks, but what if i dont want it to stop the player, i phrased the question badly, i just want a collision box that sets off a noise as the player goes through it

A zone that simply detects your presence is a triggerBox. Check isTrigger on the collider (it will no longer block anyone) and use the OnTriggerEnter event. Also see the docs. Those do detect charControllers just fine.

Exactly what i needed! Thank you

collisionObject is a transform and collision.gameObject is a game object so they will never be equal! Perhaps define collisionObject as GameObject or check the transform of collision.gameObject.

I suggest you Debug.Log both objects with .ToString(). They clearly aren't matching.
