Getting compatible with capsule - Lythom/capsule GitHub Wiki

1. If your mod have some incompatibilities you want to fix

Tips :

• Anything working with vanilla structure block will work with capsule. The easiest way to test is to setup 2 structures blocks, one saving to a template, the other loading the template. Adjust the code until the loaded area is working as expected in regard of the saved one.

• Due to the way capsule works, no tileEntity can be duplicated. It means that a tileEntity carrying a unique id is safe as it won't be duplicated: it will always be removed before replaced (eventually elsewhere).

• Note that the use of absolute coordinate to find locations inside the capsule will break (content will be moved). When it make sense: relative coordinates should always be prefered over absolute coordinates.

2. If Your mod have incompatibilities with capsule and you want capsule to ignore your block(s)

You sure it can't be fixed :'(
If so, it should't take long, follow the steps according to the version you are targeting:

1.15 or newer

Add the blocks to exclude to the capsule:excluded tag.

Documentation: https://mcforge.readthedocs.io/en/latest/utilities/tags/.
TLDR: there should be a data/capsule/tags/blocks/excluded.json file in your mod resources folder that contains something like the exemple below. Be sure that replace is "false" to keep configuration working for other mods. The block ids to exclude go into the values array.

{
    "replace": false,
    "values": [],
    "optional": [
        "#tombstone:player_graves"
    ]
}

In this example, optional should be used if the mod is not a required dependency. The # before tombstone:player_graves indicates that all the blocks under the tag tombstone:player_graves should be included here. The value could also be a block id without # to refer to a single block instead of another tag.

1.12

Open an issue on github and provide the block id to be excluded by default. I'll update the mod with the new configuration.

older

Not updated anymore. You can still add the block id in the capsule.cfg file under "opExcludedBlocks" when distributing a modpack.
