Yes. The sprite.image attribute controls which image will be shown.
So the issue would be how to access each picture into the .GIF
I modified the cocos' s example test/test_animation.py first to explore the
GIF and then to change the picture at each SPACE key release.
Attached as test_animation_2.py, put in the test/ directory so the gif can
be found.
