Depends...
where frames is the number of frames to wait
that is if the scene has a wait count check within its update method a section of code that looks like this
# If waiting
if @wait_count > 0
# Decrease wait count
@wait_count -= 1
return
end
An alternative would be to use sleep(seconds) but that pauses EVERYTHING most of the time you usually don't want that
Oh since it is a call script the above code @wait_count = frames is fine. but if it was another scene outside of call script then the above explanation applies
