World Packs

First public release.

Features

• Pick and order resource packs per world from the Edit World screen
• Joining players are required to load them — works with completely unmodded clients
• Packs are copied into the world folder, so worlds stay self-contained and portable
• The host gets the same packs applied locally, with no download
• Fully reversible — delete worldpacks.json and the world is back to stock

Notes

• Only the host or server needs this mod installed
• Packs are served over a local HTTP port: random per-session URLs, GET only, SHA-1 verified by the client, and shut down with the world
• For internet play, set a fixed port in worldpacks.json and forward it alongside your game port — the default 0 picks a random port each launch
• Only .zip packs can be served; the protocol sends URLs, so loose folders can't be sent

Known limitations

• Tested on LAN only — internet play with port forwarding is unverified
• No configuration screen on dedicated servers; write worldpacks.json by hand
• Requires Fabric Loader 0.19.0+ on Minecraft 26.2
