Sorry for the delay.
Try using a subclass of sprite like this:
class MySprite( Sprite ):
def _update_position(self):
ax = cos * sin
ay = cos * sin
bx = cos * sin
by = cos * sin
if self.render_in_subpixel:
self._vertex_list.vertices[:] = [ax, ay, bx, by, cx,
cy, dx, dy]
else:
self._vertex_list.vertices[:] = [ int(ax), int(ay),
int(bx), int(by), int(cx), int(cy), int(dx), int(dy)]
