This command will add many new details to the game, such as being able to see the helmet you are wearing, and footprints wherever you walk. It also adds trash bins and gravestones! To disable visible helmets, type /gamerule ShowHelmets false!
This vanilla mod will make weather much more interesting! It adds a daily temperature and weather alert. Warmer and colder temperatures will cause different weather. In cold weather, you must wear a coat (leather tunic). In warm water, you must drink water every so often to stay hydrated!
This command will automatically create trails where players walk often! Trails will at first be dirt, then as they are walked on more often, will become gravel, stone, andesite, and cobblestone! It even works for sand, changing it from sand to end stone, to gravel, to dirt!
