# ReiLua API ## Functions 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.event', '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.event( event ) This function will be called on events input. Content of event table is determined by event type. --- > 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. --- ## Arguments Arguments are stored in 'RL.arg' array. ## Types Raylib structs in Lua --- > Vector2 = { 1.0, 1.0 } or { x = 1.0, y = 1.0 } Vector2, 2 components --- > Vector3 = { 1.0, 1.0, 1.0 } or { x = 1.0, y = 1.0, z = 1.0 } Vector3, 3 components --- > Vector4 = { 1.0, 1.0, 1.0, 1.0 } or { x = 1.0, y = 1.0, z = 1.0, w = 1.0 } Vector4, 4 components --- > Quaternion = { 1.0, 1.0, 1.0, 1.0 } or { x = 1.0, y = 1.0, z = 1.0, w = 1.0 } Quaternion, 4 components (Vector4 alias) --- > Matrix = { { 1.0, 0.0, 0.0, 0.0 }, { 0.0, 1.0, 0.0, 0.0 }, { 0.0, 0.0, 1.0, 0.0 }, { 0.0, 0.0, 0.0, 1.0 } } Matrix, 4x4 components, column major, OpenGL style, right-handed.
