my project is a game called pirates bomb
the bomber shoot the bomb (ball) and then if it hit the ship it will explode and drown
i just want one object to be 3d
i tried to do drawBoom() in 3d but i failed<<< that's the ball that coming from the bomber (drawBomb)
i want the drawBoom() to be in 3d just that
please help me and i will be very thankful
