in short, vectors can work as if they are thin wrapped but not crash blender if the original data is removed. * RNA vector's return Mathutils vector types. * BGE vectors for GameObject's localPosition, worldPosition, localPosition, localScale, worldScale, localInertia. * Comment USE_MATHUTILS define to disable returning vectors. Example... * 2.49... * loc = gameOb.worldPosition loc[1] = 0 gameOb.worldPosition = loc * With vectors... * gameOb.worldPosition[1] = 0 * But this wont crash... * loc = gameOb.worldPosition gameOb.endObject() loc[1] = 0 # will raise an error that the objects removed. This breaks games which assume return values are lists. Will add this to eulers, matrix and quaternion types later.
