[quote:1nb3nvgu]Well that's too bad because it seems like the OnCollision Trigger "knows" there was a collision and must know where it is on the screen. Too bad it doesn't return or populate a system variable like: Sprite.OnActiveCollisionX and Sprite.OnActiveCollisionY
It doesn't know where the collision occurred, it would have to be calculated in js in the same way as listed here.
A plugin could access the collision polygon. The physics, polygon and chipmunk already do internally. In just events you could place imagepoints in the places of the collision polygon points for a brute force way. Then you can do line intersections with:
I can find a capx where i've implemented it if needed. A plugin could be made to hide the complexity, but I don't enjoy the process of updating and fixing plugins currently.
