With this datapack/mod, administrators can define a spawn point for the server start and, using a simple command, set a world border, disable PvP, and switch all players to Adventure mode. When another command is executed, the world border resets to its original size with an animation, PvP is re-enabled, and all players are switched to Survival mode. Day time and weather are also switched accordingly.

Anyone with the tag 'admin' will not be switched to any other game mode.

Usage:

1. Put the file in the mods or datapack folder.
2. Start the World or Server.
3. Find a place where the Worldspawn should be.
4. Run /function smpstart:setup
5. Whitelist all your friends.
6. Run /function smpstart:startsmp

Once the server start is finished, the mod/datapack can be removed without any problems.

If you find any bugs or have any Datapack/Mod suggestions, please let me know on my Discord.
