Having a Turret Follow A Tank

Last reply by Zamoht, about 11 years ago:

Make a new variable for your turret classes. private int cooldown or something.

Again, your approach is just wrong. It's not that you're using one class wrong here, but in my opinion it should just be rewritten here. I'll give you an example:
