Question Collider OnTriggerEnter with SendMessage

    After a Physics.OverlayCapsuleNonAlloc I'd like to send OnTriggerEnter/Exit/Stay events to a collider. This works with the following code snippet.

    Code (CSharp):
    1. otherCollider.SendMessage("OnTriggerEnter", otherCollider, SendMessageOptions.DontRequireReceiver);
    However, I'm wondering if there is a more efficient method. I'm assuming that SendMessage has to do the following:
    1. Look up all the MethodInfo's on the target collider component
    2. Potentially perform a string comparison on the name for each Method (incurring GC overhead)
    3. When (if) it finds one, check to see that the number of arguments and their types match
