MCConfig
The MCConfig mod provides a convenient graphical interface for configuring Minecraft game rules directly during gameplay. Instead of entering complex commands in the console, you can visually browse all available game rules and change their values with a simple mouse click.
The configurator is available exclusively in the game process and cannot be opened outside of a world. It's important to note that MCConfig does not affect server settings - all changes apply only to single-player worlds. All applied settings are saved and automatically applied to newly created worlds, eliminating the need to disable day-night cycle or block entity spawning each time.
The configurator interface is created dynamically, which means automatic display of any new game rules, including potential custom rules added by other mods.
For the mod to work, LazyModder version 0.74 or higher is required.
