ReiLua API

Usage

Application needs 'main.lua' or 'main' file as entry point. ReiLua executable will first look it from same directory. Alternatively, path to the folder where "main.lua" is located can be given as argument. There are five Lua functions that the framework will call, 'RL.init', 'RL.process', 'RL.draw', 'RL.log' and 'RL.exit'.

---

function RL.init()

This function will be called first when 'main.lua' is found

---

function RL.process( delta )

This function will be called every frame during execution. It will get time duration from last frame on argument 'delta'

---

function RL.draw()

This function will be called every frame after process and it should have all rendering related functions. Note: Engine will call Raylib functions 'BeginDrawing()' before this function call and 'EndDrawing()' after it. You can still use RL.BeginDrawing() and RL.EndDrawing() manually from anywhere.

---

function RL.log( logLevel, message )

This function can be used for custom log message handling.

---

function RL.exit()

This function will be called on program close. Cleanup could be done here.

RL.SetExitKey( int key )

keyName = RL.GetKeyName( int key, int scancode )

This function returns the name of the specified printable key, encoded as UTF-8. This is typically the character that key would produce without any modifier keys, intended for displaying key bindings to the user. For dead keys, it is typically the diacritic it would add to a character.

Do not use this function for text input. You will break text input for many languages even if it happens to work for yours.

If the key is KEY_UNKNOWN, the scancode is used to identify the key, otherwise the scancode is ignored. If you specify a non-printable key, or KEY_UNKNOWN and a scancode that maps to a non-printable key, this function returns nil but does not emit an error.
