Might there be a way to do both? It seems it would be helpful to have it reference only the currently picked objects with a 'sprite collides with sprite' event.
You don't need expression indexing for the sprite collides with sprite events - just the 'pick nth instance' conditions.
I'm finding a problem with useing loops with subevents
I think I see the problem in the runtime, should have it fixed next build.
There's a thing I've been wondering about. Is there a specific reason to why the keyboard and mouse objects aren't automatically added to a project?
