Right now API Reference is described as list of available functions and theirs signatures.

Signatures?

Ok, so for example lets take hello(world: string = "lua") -> nil

It's a definition of hello function which takes 1 arguments, argument is named world which has type string and has default value lua, and also returns nil

Also you could check config structure(aka conf/settings.conf) or if you ready to code here is an example

:warning: If something is not described here it's likely either internal thing or not yet added into this wiki as this wiki is written by human. ALL available API can be found on https://underlevel.ddns.net/git/quantumde1/Himmel_Engine/src/master/source/scripts/lua.d#L661

:warning: also i want to mention that all function which load something from files load files relative to engine binary, if not specified full path.
