But now I have trouble arranging pm.Poly (polygon shape) onto the body
Does pymunk shapes starts the coordinates from down below or the center?
Right now I create:
1. the tank's base's shape, pm.Poly, sized zero - Vec2d(0,0),
2. the tank's track's shape, pm.Poly, size of the whole sprite
So even the tank is upside-down, the tank will still move as the surface velocity of the track is the whole sprite...
The tank sprite's size is 20x16
I would like to attach shapes proportionally to its size according to this sprite
The tank's track would be at the bottom to 9th pixel (0-9);
While The tank's base would be at 9 pixels from below to the top; (9-16)
