Wolves now can hold sword and SPIN-ATTACK with them!

Give the wolf a sword and have fun.

Right-click and crouch to take sword from wolf.

Adding your own swords:

Out of the box wolves will use every vanilla sword and almost every modded one, so most people never need to touch this. If a sword from another mod is being ignored, you can add it yourself with a datapack.

Make this folder inside your world:

/datapacks/my_wolf_swords/

Put a pack.mcmeta in it:

{
  "pack": { "pack_format": 15, "description": "Extra wolf swords" }
}

Then create data/wolfswordmod/tags/items/swords.json inside that same folder and list the items you want, using the id shown by pressing F3+H in game:

{
  "replace": false,
  "values": [
    "somemod:ruby_sword",
    "othermod:cursed_blade"
  ]
}

Keep "replace": false so your list is added to the built-in one instead of wiping it. Reload with /reload or by rejoining the world.

To stop wolves using a sword, use the same setup but name the file swords_excluded.json instead. Exclusions win over everything, so this is how you ban a weapon that the mod picks up automatically. A wolf already carrying a sword you just banned will drop it on the ground.
