well, yes, although my codes are a lot more numerous and complex ^^.

i'll try that way:
when you hit the pause key, all sprites become invisible (you only see the current area). and all their codes are activated only if they are apparent...
that's the same idea than magnetos, although it will be checked one time in his example (there's only a main code), and in my case it will be checked as many as there are enemies on screen... so, more cpu intensive... mmmmaybe if i manage to put all the functions of my game in one and only code...? but i cannot do that without adding a lot of new _currentframe checks...

well, i'll give it a try when i'll have the time ^^
remember, it's still a work-in-progress

see you later
