I'm not sure if this suggestion or request (whichever you want to call it) would go. Here or the extension forum. Are you guys developing or planning to develope a new function for replacing objects? Like on a collision, we could change one object into another object with one command?
It's not a big deal, I know, it's just convenient.
I've been dabbling with Game Maker lately, and that's one of the very few commands in it I like.
