I asked cause unlike regular projectiles who flies in certain direction before leaving the screen, this kind of bombers would most likely be walking while finding a target and they might fill the screen if you spawn lot of them
If they hit a target or something, you won't have to worry as they'll be removed after hitting but if not or if there's nothing to be targetted at, they will wander around
Having too many of them on screen is my biggest concern that's why I asked
Anyways, one solution is to give lifespan to this bombers to they will die after some time if they can't find any target. This way, no matter how fast player spawn them, they will remove themselves and won't clutter the field
