Re Cell Graphic feature:
None of the "solutions" posted in this topic address the problem. What every "solution" does is eliminate one problem and ignores the fact that this method simply does not work.
As an example a familiar scene from JSW edited very slightly to include a ramp, a stair and a conveyor. JSWED has drawn what should be drawn by the game in the room. If the fix does not draw the graphics as shown, then the fix has not cured the problem.
In the case of the three graphics Stair-Ramp-Conveyor all being in the same room. Matthews code can not handle this scene properly. (The conveyor will cause the most problems in horizontal animation/movement)
Remove the conveyor and change its colour, then this room would play with these graphics exactly as expected.
I have posted a method elsewhere that draws exactly what was defined.
