Mod for Luanti: Highlighter Pen
I wrote a novel Luanti mod, that works in any game. I have tested it specifically in the following games.
- Mineclonia, also on ContentDB
- Minetest Game, also on ContentDB
- VoxeLibre, also on ContentDB
Description
This mod for Luanti adds highlighter pen tools. A player can highlight nodes, and erase highlights. The highlights persist after a safe server restart.
The canonical scm repo for this mod is at https://bgstack15.ddns.net/cgit/luanti/highlighter_pen, and an additional repo suitable for collaboration is at https://gitlab.com/bgsack15/highlighter_pen.
Using
Craft a highlighter pen. Right-click a node with the tool to set a highlight. Left-click to remove a highlight on a node.
Craft and use a blotter to remove highlights in a small radius (default radius is 3).
Dependencies
- Vendors node_highlighter because that is not in ContentDB. You can also use that mod, and it will load that instead of using the vendored components.
Optional dependencies

Settings
- How many nodes can a highlighter pen be used in survival mode on before the pen runs out (default 200)
- Highlighter pen can erase all highlight-colors from a node (default true)
- Using a highlighter in the air (an empty node) erases this color entirely, on all nodes (default false)
- Blotter radius, where 1 is the single node that was right-clicked (default 3)
Current weaknesses
- The blotter is the only component that respects
core.is_protected, and only on the center of the usage. - Unifieddyes does not produce highlighter pens for each color variant for creative mode inventory; you have to craft them.
