I’d like to create a shooter game where a hero player throws balls at enemy units. Just like PKT Ball, how do you create an illusion that a ball is floating from the ground when the perspective is bird’s eye view?

You can also change the scale of the ball. When it is higher off the ground, it should appear larger because it is “closer” to the user.
