Setting a sprite's anchor points for handling in movement,
animation, collision etc.
5. New visual attributes for sprites:
- Rotation angle
sprites anchor point should be just an offset, not limited to
'topleft', 'midtop', 'topright',... and the other rect
I want to be able to specify "center" or "midbottom" for
the sprite anchor without knowing the image's dimensions. And
I want that anchor point to remain in the appropriate place
even if the image is rotated, scaled, or flipped. I'm not sure
that an offset would accomplish this, but if so, then that's
I agree, what I suggested is that both things should be possible: a
general offset and/or specifying 'center' or 'midbottom' or....
I'm not sure right now how the math to maintain the point at the
appropriate place. Maybe this needs some more specification for the
different transformations (rotation, flip, scale).
