python - Mouse Movement in Pygame when selecting objects does not seem to work -
i making small game using pygame, , @ moment have 5 balls falling top of screen , landing on pile of boxes destroy knock them down. @ moment seems work fine however, trying select balls mouse when balls fall down able select them again , return them original position.
here code program

the problem seem indenting code
elif event.type == mousebuttondown: p = from_pygame(vec2d(event.pos)) selected = space.point_query_first(p) one level much. change if instead of elif. tried changing , move balls using mouse.
hope working now. :)
