Lua scripting

Game modes and server features are Lua resources that the server runs and that act on the game only through the dlmp API. These pages are the contract resource authors rely on:

Page	What it covers
Resources	The resource folder, the resource.toml manifest, dependencies, require and dlmp.import, client files, storage, and start, stop, reload and shutdown
Elements	Element families, ownership, handles, players, and events whose source was removed
Events, commands and timers	Subscribing to events, their order and refusal, player and console commands, timers
Errors and the sandbox	nil, err versus raised errors, errors in callbacks, the libraries, the time limit and what a resource cannot reach

The function-by-function API reference is built from resources/.types/dlmp.lua, a type stub for Lua language servers that editors read for completion and checks. The shipped resources in resources/ are working examples, and the guides walk through parts of them. Decisions behind the API are in the architecture decisions; what crosses the wire is in the protocol.
