To clarify, I want to make a automatically generated map with premade tiles and link them up. I am not sure how to make wave function collapse, if there is any other alternatives that’d be nice (the tiles are also of varying sizes)
You can have certain sets of tiles generate in certain patterns based ones that you save, so it would be like a matrix of configuration
Like this chunk of tiles has this biome, in this pattern, rotated this way.
Then you have more tiles but another pattern you select!
Basically just chunk configuration
So to have certain patterns hard coded and to use them to determine possible tiles for exits and entrances?

And if you need an exit or entrance, generate the chunk to be compatible with the new tiles!
Theres some sorta plugin for that
https://create.roblox.com/marketplace/asset/5459691708?viewFromStudio=true&keyword=&searchId=6581BFDE-777C-4955-9A2D-073289A611DF
If you have some sorta plugin (RoPro etc.) You could look through the source code.
Update: I dont think the plugins work anymore since they updated the website, plugins arent updated yet
You can still use the old links by removing create from the front and replacing marketplace with catalog.
What kind of generation are you going for? Dungeon generation with rooms and hallways? More naturally generated dungeons like Pokemon Mystery Dungeon? Or are you talking about terrain here?

INFO: THIS DOES NOT WORK, YOU NEED TO INSTALL THE WHOLE DATA AND CUSTOMIZE IT ON YOUR OWN.
sorry you went out of your way to get this, but what i need is a tile based map, not a terrain based
i tried doing this but i cant get the exits and entrances to line up, i have bothj on seperate models, under the folder links to show how it can link, i cant get two models to line up a links, any ideas?
If you can make sure every tile is the exact same size and every tile matches up in some way being rotated
Could you give a more specific explanation or preferably a visual example of what you’re trying to do exactly?
i figured it out with help from a friend, thanks everyone
Im actually very interested? Do u mind asking how?
Basically you have a list of entrances and exits for 2 rooms to connect and you basically just make it so every entrance and exits front vector looks out, and you can set the primary part of the model to connect to be the entrance which will be connected to the exit and set primary part cframe that and make it so it looks forward using the .LookVector of the exit and verify that it is a possible layout using some hitbox collisions, if its possible place it. and at the end i do a trimming bit where if there is no exits leading anywhere it’ll destroy the tile basically and make sure everything is linking to eachother and that there isnt floating bits of the map just incase and i do it via brute force trying every available exit

I know this issue has been solved, but doenst that have to do something with ChangeHistoryService? Or am i wrong
