ok thanks but I want that when the
player enters another chunk so it
spawns and not infinitely, only once
vs
basically an object is randomly
spawned in an area and the same object
infinite generation
I see you’ve changed your mind about it 
BTW if not understanding then play
subway surf I am making my game like
this
How about you explain what you need, in fine detail and with screenshots rather than send me off to play a game…
