Set all blocks in an instance container into air

[Codestech1]

Hi, how can I set all blocks in an instance container into air?

For what purpose?
It might just be easier to create a new instance without any loaders or generators depending on what you want to do.

I am coding minigame right now and i don't want to create new instance on game restart, i just want to clear all blocks to don't make trash in the cache.

Again, found it by myself

instance.chunks.forEach {
    it.sections.forEach { sec ->
        sec.blockPalette().getAllPresent { x, y, z, value ->
            if (Block.fromStateId(value.toShort()) != Block.AIR) {
                gameInstance.setBlock(x, y, z, Block.AIR)
            }
        }
    }
}
