Hello and thanks for your support!
And yes, it’s possible to have unique rooms. There are basically two possible approaches:
- You can have a room template that you only assign to a single room in the level graph. By doing so, you can be sure that it’ll be used at most once in the level.
- Or you can use the “Repeat mode” option that is available on each room template. (https://ondrejnepozitek.github.io/Edgar-Unity/docs/basics/room-templates#repeat-mode) You can choose that the room template must not be used multiple times in a level. Just be sure that you don’t overuse this feature because the generator might have problems generating very constrained levels.
