MCDanmaku
by NyaShulker
MCDanmaku shows live Bilibili danmaku, the scrolling chat messages of a streamer's room, inside Minecraft's in-game chat.
What it does
Once a live room ID is set, the client connects to that room and prints its danmaku in the chat as they arrive. Changing the room ID while the client is running takes effect immediately, so a restart is not needed. Stopping the feed closes the WebSocket connection, and messages from old connections are discarded. A status line shows the current client state and room ID.
Logging in is optional. The mod can request a Bilibili QR login session, start a temporary local HTTP server and show the link in chat. The player scans the QR code with the Bilibili mobile app, confirms on the phone, and the resulting cookie is saved in the local config directory. A command removes the saved login data again. Because Bilibili's live danmaku APIs and login flows can change, the mod may need updates to keep working.
MCDanmaku is a client mod on Fabric and requires Fabric API. It is client-side only, so the server does not need it. Files exist for 26.2 and 26.3, and the latest Fabric file is 1.0.1 for 26.3, published on 2026-09-16. Snapshot builds are published, and the code is open source under the GNU General Public License v3.0 only.
