I have an object that creates a ball and shoots it at another "receive" object that is the same object as the "spawner" object.
I know the UID of the receiver object but I can't figure out how to check that the object the ball is colliding with is correct receiver object or not.
While writing this I thought of the solution... so for anyone else who has the same issue...
Since I knew the UID of the object I wanted to collide with, I had to add a 'Compare 2 values' event after the collision event that checked the UID of the colliding receiver to equal the saved UID variable.
(pat on my back).
