I'm making a projectile system where marines shoot bullets and the bullets are actualy units so the marines can hide behind cover and stuff.The problem is,for it to look good the marines need a low cooldown and that creates many bullets,so it lags a lot.How can i make it look like one bullet is a couple of bullets or some way to speed up the thing.I unleaked it and everything,but in the end the game just cant handle so many untis spawned at once.
