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.
• base64: contains the base64.encode(data) function to base64 encode a string as well as base64.decode(data) to decode
