# 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 seven Lua functions that the framework will call, 'RL.init', 'RL.update', 'RL.draw', 'RL.event', 'RL.log', 'RL.exit' and 'RL.config'.

---
> function RL.init()

This function will be called after window has been initialized. Should be used as the main init point.

---

> function RL.update( 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 update 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.

---

> function RL.config()

This function will be called before InitWindow. Note! Only place where you should call InitWindow manually. Doesn't have OpenGL context at this point.

---

> function RL.load()

This function will be called when loading resource that allocates memory. Usefull for memory leak debugging. Note! Cannot detect all resources, for example material textures.

---

> function RL.unload()

This function will be called when unloading resource that has allocated memory. Usefull for memory leak debugging. Note! Cannot detect all resources, for example material textures.

---

## Object unloading

Some objects allocate memory that needs to be freed when object is no longer needed. By default objects like Textures are unloaded by the Lua garbage collector. It is generatty however recommended to handle this manually in more complex projects. You can change the behavior with SetGCUnload.

## Arguments

Arguments are stored in 'RL.arg' array.
