yes, i got that part, it just doesnt return to the calling function after the wait, the whole function stops after it (and doesnt move on the next frame).

I just used the wrong terminology there, i'm sorry, "terminated" should've said "quit without resuming".

The manual doesnt say anything on that (not under engine_getscript or under wait).
Or i'm getting it completely wrong, and the manual should be more clear about that?
