I was trying to recreate Tendry's Grappling Hook from TSS, and ran into an unusual snag. I set up a system that waits for the player to teeter on a pit edge, then sets _MyScriptX to _O and checks the "Wait for Player to Input" command. And it works perfectly, except when I try to grapple northwest. Eventually, I tried adding a speech command directly after this check, and sure enough, it wasn't actually triggering.

My own testing shows that an entity which first sets _MyScriptX to a number and then waits for player to input northwest (which should be overwritten by that value) before talking, talks if the var is set to 1/2 and the player inputs north/northeast; and does not talk if it's set to 0 and the player moves northwest. It's possible more extensive testing would reveal that northwest corresponds to some random other number, though. I don't think I've ever actually used myscript with this particular command before, as all of the use-cases I've had for "wait for player to input" were either just for special command, or in case branchings that were simpler without using myscript.

Looking in the code, this isn't really a bug. While all the other movement commands map to their orientation, Northwest doesn't. If you look at the appropriate Game Constants, it turns out that command 0 is undefined, and it's command 11 that's northwest.

This is probably something that can't be changed, since it would break all the demos. Since breaking any of the demos is Not Allowed, that obviously presents a blocker. You'll just have to add a special case for NW movement.

Cool, thanks hyperme! I'll add this info to the myscript primer.
