/level admin command valid blocks

  • Hi ok this one is probably going to be for a developer because only they
    will probably know this.

    For the admin command /level the format is
    /level x,y,blocktype

    /level [x(default=10)],[y(default=10)],[BlockType(default=GrassBlock)]

    So basically what are all the blocktypes that you can use there
    Other than GrassBlock

    Can any of the devs give a full list of all the block names that you can
    use there because so far I can't find them anywhere and the
    only thing i can get it to do is spawn Grass Blocks but say what
    if I wanted to spawn water.

    Can a dev give us the full list of all the valid block names
    for this admin command

    Thank you,
