Japes!

Paper balls, folded notes and renamed signs give players light, playful ways to tease each other. Crafting a paper ball is possible, and throwing one at another player can make the target drop their held item when their hand is empty. Creating a folded paper uses sneak and the use key, and a note can be unfolded later to read it.

Some tricks affect combat. Interacting with a block near other players can briefly give the user a combat advantage, and a taunting sign can be obtained by renaming paper and kicking it. Shoelace tying lets a player sneak-interact with someone's feet to untie their laces, and a looking-down disarm removes an item from a target. An item called a leash is craftable from a wind charge, and a chat message can announce a lost game.

The mod runs on both client and server, so the server and every player need it installed. It is published for Fabric only, on game version 26.1 – 26.1.2 with three release versions, and the code is under the European Union Public License 1.2, which makes it open source. It requires Fabric API and Trinkets Updated.
