Modifying an Existing Sticker Pack

You can use the JSONPatch feature to add or remove stickers from an existing sticker pack.

For example, to add to Boyfriend's standard sticker pack, you can use the following JSON Patch file (placed in mods/mymod/_merge/data/stickerpacks/standard-bf.json, use a different file path to patch a different sticker pack):

[
    // Add an asset path to the end of the sticker list.
    { "op": "add", "path": "/stickers/-", "value": "path/to/custom/sticker" }
]
