Screen->ComboS[] does not act like the documentation states.
I needed to know the specific walkability of combos for a script I'm working on. Since the script was not working right, and I knew my logic was sound, I tested all 16 return values of ComboS[] with Trace(). Guess what I learned?
The least significant bit is true if the top left corner is solid.
The second-least sig. bit is true if the bottom left corner is solid.
The third-least sig. bit is true if the top right corner is solid.
The most significant bit is true if the bottom right corner is solid.
The documentation is almost completely wrong. (And frustrating! :googly😊 I would suggest fixing the documentation and leaving the functionality the same.
P.S. (While you're here, did you know that Link->Z is not documented? I wonder what else is hiding...)
