I hope my title isn't too confusing...basically what I want to do is check if "Object Collision A" collided with "Trigger B" from a script attached to "Object C".
So both "Object A" and "Trigger B" don't have any scripts attached to them, only "Object C" does.
Thanks in advance!
You can test in script against either the name of the object or the tag. Do a search for collider/ name/tag in the unity docs for how.
But you may a well attach that same script to each trigger. Then I think u can do a if this.name "triggername" and collider.name then do whatever.
