Further to my previous messages in this thread...

In a forthcoming project that I'm working on, I've been playing around with Patch Vectors that toggle the current room's Conveyor Direction Byte (Offset #D6 in the room buffer), via an XOR 01 command. That has the effect of switching the direction of standard conveyors - both the animation and the conveying action (the effect on Willy's movement) are reversed.

However, when applied to Off or Sticky conveyors , the 'mechanical' effect is to toggle between those two conveyor types, but the animation of the conveyor's top pixel-row is always rightwards (whilst the third pixel-row is always rotated to the left for Off and Sticky) - notwithstanding the appearance of the conveyors in JSWED (which shows Off conveyors animating leftwards and Sticky animating rightwards).
