I have been working on procedural generating levels. I have created boxes who have a spawn depending on their opening.
If a box has a left spawn. the left spawn will know that it needs to create at least 1 door on the right. This seems to be working, but for some reason, after a while, the rooms start stacking on top of each other. even tho my code does not allow this?
Could this be because the walls are not in the perfect symmetry of eachother? Since I want to have broader and different kind of levels I thought having only the spawn points align would be enough?
This is how the level starts 4 different pathways.
Still going good
Still good
As you can see every entrance from the Starting floor have been blocked.
After this they keep stacking op top of eachother giving no end to the generation of levels.
