I want to make a projectile that is curved in a game like 8d, I heard that I need to use a square function but I couldn’t apply it
Can you describe this a bit more, and maybe include an image of what you mean?
I would look at using a position tween on the projectile from player to zombie. Use the projectile.Tween::Progress() to get how far along it is, and use a formula like
(0.5 - projectile.Tween::Progress("tweenName"))^2) as the square function.
Can you simplify this into actions and conditions?
