Data-Pack / Game-Rule Menus

This mod brings the datapack and gamerule management menus from the world creation process into existing singleplayer worlds. Now you have a convenient graphical alternative to the standard /gamerule and /datapack commands.

It's important to note that access to these menus is only available in worlds where cheats or commands are enabled.

Datapack Management Features

The mod allows you to not only manage datapacks but also toggle experimental game features. However, it's worth considering that some types of datapacks require world reloading for changes to take full effect.

System Warnings

In most cases, the mod automatically detects the need for reloading and shows an appropriate warning, offering to either cancel changes or exit the world properly. But there are exceptions:

Registry packs (the new type in MC 1.21) are not detected by the mod but still require world reloading. If you toggle such packs without reloading, errors may appear in the logs, but they are harmless provided you reload the world immediately.

Experimental features are properly detected by the mod. When toggling them, the corresponding feature flag in the world is automatically activated followed by a proper exit.

Vanilla Datapack

Technically, you can disable the standard vanilla datapack, but this is not recommended. Such action may disrupt world functionality if you're not sure what you're doing. An additional warning will appear when attempting to disable it.

If the world fails to load after disabling the vanilla datapack, try loading it in safe mode for recovery.
