Graphics / Re: Ball doesnt change his start position

What do you mean by isn't linked,  isn't it enough to write something like Shot. Position = Rect. position like I did for the start position before the movement begin.

But okee I will try to implement what you wrote and post it later?

OK thanks, now I see the mistake by the movement

 Position.X - Position.X + Size.X, Position.Y - Position.Y + Size.Y)
 

But, why need the circle a rotation? I just want that the start position of the circle is always by the top of the rect.
This was my attempt but it failed.

CircleShape Shot = new CircleShape(5);
                    Shot.Position = new Vector2f(Position.X, Position.Y + Size.Y * 2 / 3);
                    ShotList.Add(Shot);
                }

Hi There,

i have a problem with the rotation. My goal was to rotate a Rect and make it shoot by pressing left mouse button or space.
The rotation works but not the shoot. The ball always fly away from the same position no matter if the Rect rotate or not.

Here an example picture
