This mod is for the free game Luanti, now specifically for the VoxeLibre fork.

Commands;

• pos1 = set the first corner of the area to be edited
• pos2 = set the second corner of the area to be edited
• fill_type = choose the selection shape: "fill_type rectangle" (default) or "fill_type sphere". Sphere is fitted inside the pos1/pos2 box, so a non-cubic box gives an ellipsoid. Works with replace, fill, delete, copy, and save
• setnode = set the node for replacing to either the node held or the node specified
• replace = by default no values, replace area selected with setnode; accepts wildcards such as mcl_core:* and "setnode" as a node name
• fill = completely replace everything in the area with setnode or the node specified; accepts wildcards and "setnode"
• delete = replace everything in area with air; accepts wildcards such as mcl_core:* and "setnode"
• replace and fill run each new block's constructor; liquids start flowing and mob spawners start spawning after replace, fill, paste, load, undo, and redo
• water = a filter keyword usable with delete, replace, and fill. It means any liquid, so "delete water" removes liquids and "replace water " or "fill water " fills liquids with that node
• copy = save the non-air blocks, their metadata and timers, and any entities in the area to the internal clipboard; the clipboard is trimmed to the outermost blocks, so empty space around them does not add an offset
• rotate = rotate the copied blocks and entities in place by 90, 180, or 270 degrees before pasting. Rotations add up; run rotate with no value to see the current rotation
• paste = load the blocks, metadata, timers, and entities relative to your position
• save = save the selected blocks, their metadata and timers as .txt in replace_data
• load = load a saved slot at pos1
• undo = undo last action, including removing the entities that a paste spawned
• redo = redo last action after being undone, including respawning its entities

Known issue: mob spawners, when filled, can have so many entities that the game will glitch.
