Builderdash
Builderdash, a Fabric minigame, pairs players in a building competition where each round gives both players the same prompt and the whole party votes on the builds.
What it does
Builderdash is a building-related party minigame built on the Plasmid API. Players join an open game, and in the building round each pair works on a prompt while the others watch. In the voting round the two builds of a pair appear side by side, and every player in the party votes for the one they like better. Custom prompts can be added, and a versus mode with pictionary and telephone variants is included.
The mod runs on the server alone, so players can join with a vanilla client. Players connecting from a LAN-hosting client with the mod installed also work. Its required dependencies are Fabric API, Plasmid and Polymer. Builderdash is open source under the GNU Lesser General Public License v3.0 only, and files are published for Fabric across 1.21 – 1.21.8, with 0.1.3+1.21.8 for 1.21.8 as the latest build. The source code and issue tracker are public.
