Thank you guys.
alextro: Puuh, pretty hard stuff for me. Sorry, but I don't get the code right now. But I'll keep on trying
plinkie: If I destroy the object immediately after spawning (in the case it overlapps an already spawned object) it destroys the object which is already there too. Which is not what i'm going for.
If I substitute the imagepoints by objects (spawner-sprites) and give them a variable, how do I address them in the random-spawn event? Right now, I'm working with:
system > every x seconds > Spawn-Object (the one with the image-points) > spawn family-objects (imagepoint random(1,10))
Thanks again
