Unstable SMP System
A Bedrock add-on built for SMP servers and creators. It adds a death sound for the whole server, custom join and leave messages, and blocks player chat. The game chat is also moved into a small, clean style that stays inside the frame when you record or stream.

WHAT IT DOES
- Death sound: when a player dies, a custom death sound plays for everyone.
- Kick on death: the player who died is removed about 2 seconds later (works on servers, may not work in single-player worlds).
- Player chat is blocked: normal player messages are cancelled. Only system messages show, like death messages and join/leave messages.
- Custom join and leave messages shown in chat.
- Creator-safe chat: smaller text (75%) and moved in from the left edge. Wide phone screens crop the sides when you export a 16:9 video, which used to cut off death messages. This keeps the text inside the frame.
- Custom HUD icons texture included.
REQUIREMENTS
- Minecraft Bedrock Edition, stable release. Tested on 1.26.50.
- Uses Bedrock scripting for the behavior pack (@minecraft/server 1.8.0).
- For the death kick to work, play on a server or world where commands can run.
INSTALLATION
- Download the .mcaddon file.
- Open it. Minecraft imports both packs.
- Create or edit a world and turn on the Behavior Pack (it also turns on the Resource Pack).
- Join the world. If you update from an older version, remove the old packs first so you do not get duplicates.
NOTES
- The safe margin is made for phones up to roughly 21:9. Wider phones may still clip a little, and 16:9 screens do not need it.
- Because it blocks player chat and kicks on death, only use it on worlds and servers where you want that.
