I think it was trying to access an out of bounds element of the array. spot SP[20] when it only goes up to SP[19]. it is no longer crashing, as my incrementing was happening before calling the array not after. But I would still like some feedback about using multiple QGraphicsView/QGraphicsScene ( say like 200pixels by 50pixels for one animation sprite and loading the Pixmaps like the above code ) verses using just one large QGraphicsView/QGraphicsScene and having it handle all the refresh events of all the sprites...
