Hot Tub

Make a hot spring pool with a layer of soul sand and water. Dig out a square pool and fill in a layer of soul sand. On top of the sand, put in water and you have a bubbling pool of warm water. With this mod, you can build a small, cozy spa tub or huge bubbling lake!

Try the code:

player.onChat("hottub", function (num1) {
    blocks.fill(
    AIR,
    pos(0, -2, 0),
    pos(num1, -2, num1),
    FillOperation.Replace
    )
    blocks.fill(
    SOUL_SAND,
    pos(0, -2, 0),
    pos(num1, -2, num1),
    FillOperation.Replace
    )
    blocks.fill(
    WATER,
    pos(0, -1, 0),
    pos(num1, -1, num1),
    FillOperation.Replace
    )
})
