I'm making a game where the story has an unseen character throw an object from below the screen. All I want is for the object to appear on screen and move as if it was thrown in the air(like in a parabola). I also want it to disappear from the world as soon as it reaches the other side of the parabola to show it as if it left the screen. I'd also like it to appear from random places at the bottom of the screen and different sizes of a parabola.
