I tried using the following code to support Undo actions:
if(!doc->AddUndo(UNDO_CHANGE,op)) GePrint("AddUndo(UNDO_CHANGE,op) failed!");
//actually set new coords
p[frontpoint] -= result ^ axisstate;
Where p is the PointObject pointer of op, which is the currently selected object. Only one point in the object gets moved.
When I try to undo it seems to work, but trying a second undo or a redo, cinema will die with an unhandled exception.
Any suggestions? Am I AddUndoing the wrong object?
