Development Tools

This article lists various free software tools which help in development of Minetest and mods for Minetest.

Minetest development

• Development Test: A testing game for testing various engine features
• /minetest/util: Various maintenance utilities

Mod development

Standalone software

• NodeBoxEditor: Build node boxes by dragging their edges.
• MTS Editor: A program to create, view and edit Minetest schematics, but it supports other file formats (e.g. Minecraft schematics) as well
• Schematic Creator: A Java program to create schematics
• Model Creator: A Java program to create meshes
• RocketLib Toolkit: Lua-based SQLite3 map reader
• luacheck: Lua linter and static code analyser (see also the chapter rubenwardy's modding book)
• busted: Lua unit testing framework (see also the chapter rubenwardy's modding book)
• Perlin noise tuner Visualizes the perlin noise Minetest will generate with different noiseparams. (Emulation of Minetest perlin can be wrong in extremes/edge-cases due to precision of javascript number type)

Scripts

Translation

• update_translations: Python script to create and update mod translation files
• findtext.lua: Create mod translation template (buggy!) (see also)
• updatetext.lua: Update mod translation template (buggy!) (see also)

Mods and modpacks

• Schematic Editor [schemedit]: Advanced tool for creating and placing schematics
• Convert table schematic to .mts [saveschems]: Tool for converting schematics from Lua table format to MTS files
• WorldEdit: Primarily a tool for editing large parts of the world, what's interesting for developers is that it includes a few basic schematic commands (//mtschemcreate, etc.)

• Find Biome [findbiome]: Server command for finding a biome and teleporting to it
• Inventory Check [inventorycheck]: Investigate the inventory of any player
• Inspector [inspector]: Reveal the item/entity definition, metadata and param1/param2 of whatever you punch
• Prysm [prysm]: Test Perlin noise on-the-fly
• Advanced Rangefinder [finder]: Adds search capabilities for both nodes and entities and related server commands

Benchmarking
