Ice Age

Aquatic creatures have been trapped in ice for a long time. Watch as they thaw out and come back to life!

Try the code:

let rando: Position = null
let topCorner: Position = null
let bottomCorner: Position = null
let layers: number[] = []
player.onItemInteracted(TRIDENT, function () {
    layers = [LAVA, GLASS, ICE]
    bottomCorner = pos(10, 0, 10).toWorld()
    topCorner = positions.add(
        bottomCorner,
        pos(10, 10, 10)
    )
    for (let index = 0; index <= layers.length - 1; index++) {
        blocks.fill(
            layers[index],
            positions.add(
                bottomCorner,
                pos(index, index, index)
            ),
            positions.add(
                topCorner,
                pos(0 - index, 0, 0 - index)
            ),
            FillOperation.Replace
        )
    }
    for (let i = 0; i < 20; i++) {
        rando = randpos(
            positions.add(
                bottomCorner,
                pos(2, 2, 2)
            ),
            positions.add(
                topCorner,
                pos(-2, 0, -2)
            )
        )
        blocks.place(WATER, rando)
        mobs.spawn(TROPICAL_FISH, rando)
    }
})
