I am struggling with the Z value as well. said he’ll be providing a demo of how to properly wrap the theme override. I’ve marked that particular part of my project as blocked (from a planning perspective) until that demo is made. If you figure it out I’d love to hear your method. I had not even used an event listener, but rather just made a platform guaranteed to be a room and made a thin override which makes it so one wall of that room is an empty theme. I then made a static wall with a door which lined up properly with generated dungeons. This works really well except for the Z value of the connected room. Sometimes the room is on Floor 2 of the dungeon and it is no longer aligned with the door I created.
