Yeah I know, I wasn't thinking straight.
But the stairs + bridge gotta be 1 big event Character with empty events or "blocked-when-on" RegionID around it so the player doesn't walk off, right? And the lights and building each are also big Event Characters then...
If I want to use UltaMode7 I think I would need to have a H-mode. My game uses different floor levels to solve puzzles and I'm using the Characters I shared here earlier as walls. It looks fine in 2D but only the walls pop up when UltraMode7 is used and not the first, 2nd or 3rd floor which is the tileset of course.
