hi,there is something that is really wanna know about buildbox, how do we dispose/clean the objects and previous scenes that are no longer on screen. for example-if i spawned an enemy every second,now when these enemies go off the screen how do i dispose these objects properly so that the performance of i game is not affected?? recently i spawned many enemy per second and my game became very slow.. can anyone tell me how do i avoid this issue so that it doesn't happen when i test it on simulator and later on a real device??
