Documentation

This directory contains mostly reference documentation for the Luanti engine. For a less prescriptive and more guiding documentation, also look at: https://docs.luanti.org

Note that the inner workings of the engine are not well documented. It's most often better to read the code.

Markdown files are written in a way that they can also be read in plain text. When modifying, please keep it that way!

Here is a list with descriptions of relevant files:

Server Modding

• lua_api.md: Server Modding API reference. (Not only the Lua part, but also file structure and everything else.) If you want to make a mod or game, look here! A rendered version is also available at https://api.luanti.org/.
• builtin_entities.md: Doc for entities predefined by the engine (in builtin), i.e. dropped items and falling nodes.

Client-Side Content

• texture_packs.md: Layout and description of Luanti's texture packs structure and configuration.
• client_lua_api.md: Client-Provided Client-Side Modding (CPCSM) API reference.

Mainmenu scripting

• menu_lua_api.md: API reference for the mainmenu scripting environment.
• fst_api.txt: Formspec Toolkit API, included in builtin for the main menu.

Formats and Protocols

• world_format.md: Structure of Luanti world directories and format of the files therein. Note: If you want to write your own deserializer, it will be easier to read the serialize() and deSerialize() functions of the various structures in C++, e.g. MapBlock::deSerialize().
• protocol.txt: Rough outline of Luanti's network protocol.

Misc.

• compiling/: Compilation instructions, and options.
• ides/: Instructions for configuring certain IDEs for engine development.
• developing/: Information about Luanti development. Note: developing/profiling.md can be useful for modders and server owners!
• android.md: Android quirks.
• direction.md: Information related to the future direction of Luanti. Commonly referred to as the roadmap document.
• breakages.md: List of planned breakages for the next major release, i.e. 6.0.0.
• docker_server.md: Information about our Docker server images in the ghcr.
