Hydra API documentation

Lua version

Hydra uses gopher-lua, Lua 5.1

Globals

arg: table containing command line arguments
hydra: contains minetest protocol API, see hydra.md
vec2, vec3, box: vector library, see vector.md

Additional packages

require() can be used to import these modules.

escapes: contains utility functions to deal with minetest escape sequences, see escapes.md
client: a function to create a client from command line arguments in the form <server> <username> <password>. This is trivial but so commonly used that this function was added to avoid repetition in scripts.
