To create a new cell to add to the pool, there are a few things you need to do.

The first is that you need to create a schematic using World Edit. This is fairly simple to do. You need to use a wooden axe to select two points (left click for the first point and right click for the second). Everything between these points will be part of the schematic.

Once you have the area selected that you want to make into a cell, stand where you want the player to be placed when they teleport to that cell. Then use //copy -b. The portion at the end will allow you to copy the biome there as well, if you don’t want to copy the biome then you can just use //copy.

Now that you have it copied to your clipboard, you need to use //schem save [name]. This will save the schematic in World Edit’s config folder in the schematics folder.

Copy or move the schematic into the Wormhole’s config folder inside of the Schematics folder.

Then, you need to create a new json file to create the cell. Here is what that file should look like:

{
  "cellID": "example_id",
  "cellOffset": [
    0,
    0,
    0
  ],
  "spawnOffset": [
    0,
    0,
    0
  ],
  "schematic": "[path_to_modpack/server_files]\\config\\Wormholes\\Schematics\\[filename].schem"
}

The file name needs to be the same as the cell ID with .json after. For this example, the file name would be example_id.json

For the cellOffset and spawnOffset you don’t need to change initially. When they are set to 0,0,0 it will automatically create those so the cell is placed in the right location. But should it not be where you want, you can adjust it after the fact.

Once this file is added you can use the /reload command and the mod will load the new cells as well.
