> A modified version of ReiLua with embedded main.lua, embedded assets, splash screens, and asset loading system
+This is an enhanced version of ReiLua featuring:
+ReiLua brings the power and simplicity of Raylib to the beginner-friendly Lua language in a straightforward manner. It is a loose binding to Raylib - some functions are excluded and some are added. The concept of pointing to a "main.lua" file and accessing functions "init", "update", and "draw" is borrowed from the Lรถve game framework.
+Note: ReiLua is lovingly handcrafted and will likely contain bugs and documentation errors, so it would be much appreciated if you would report any such findings. +Reilua means "fair" in Finnish. +This enhanced version is built upon:
+ReiLua is WIP and some planned raylib functionality is still missing, but it already has over 1000 functions. Current Raylib version is 5.5.
+List of some MISSING features that are planned to be included:
+Development Mode (Fast Iteration):
+# 1. Create your game files
+GameFolder/
+โโโ main.lua
+โโโ assets/
+โ โโโ player.png
+โ โโโ music.wav
+
+# 2. Run ReiLua pointing to your game folder
+ReiLua.exe GameFolder/
+
+# Or from your game folder
+cd GameFolder
+path/to/ReiLua.exe
+
+# Skip splash screens during development
+ReiLua.exe --no-logo
+
+# Enable console for debugging
+ReiLua.exe --log --no-logo
+Release Mode (Single Executable):
+# See "Building for Release" section below
+Create a main.lua file:
local textColor = RL.BLACK
+local textPos = { 192, 200 }
+local textSize = 20
+local text = "Congrats! You created your first window!"
+
+function RL.init()
+ RL.SetWindowTitle( "First window" )
+ RL.SetWindowState( RL.FLAG_VSYNC_HINT )
+end
+
+function RL.update( delta )
+ if RL.IsKeyPressed( RL.KEY_ENTER ) then
+ local winSize = RL.GetScreenSize()
+ local measuredSize = RL.MeasureTextEx( RL.GetFontDefault(), text, textSize, 2 )
+
+ textColor = RL.BLUE
+ textPos = { winSize[1] / 2 - measuredSize[1] / 2, winSize[2] / 2 - measuredSize[2] / 2 }
+ end
+
+ if RL.IsKeyPressed( RL.KEY_SPACE ) then
+ textColor = RL.RED
+ textPos = { 192, 200 }
+ end
+end
+
+function RL.draw()
+ RL.ClearBackground( RL.RAYWHITE )
+ RL.DrawText( text, textPos, textSize, textColor )
+end
+Run it:
+ReiLua.exe --no-logo
+ReiLua looks for a 'main.lua' or 'main' file as the entry point. There are seven Lua functions that the framework will call:
+RL.init() - Called once at startup for initializationRL.update(delta) - Called every frame before draw, receives delta timeRL.draw() - Called every frame for renderingRL.event(event) - Called when events occurRL.log(logLevel, message) - Called for loggingRL.exit() - Called when the application is closingRL.config() - โ ๏ธ Deprecated in this versionAll functionality can be found in "API.md".
+This version includes customizable splash screens that display at startup:
+Screen 1: Custom text - Bold text on Raylib red background (customizable) +Screen 2: "Made using" - Displays Raylib and ReiLua logos side-by-side +Each screen fades in (0.8s), displays (2.5s), and fades out (0.8s) for a total of ~8 seconds.
+Skip During Development:
+ReiLua.exe --no-logo
+Customize:
+src/splash.clogo/ foldersrc/splash.cSee SPLASH_SCREENS.md for full documentation.
+Beautiful loading screen with progress tracking:
+function RL.init()
+ -- List your assets
+ local assets = {
+ "assets/player.png",
+ "assets/enemy.png",
+ "assets/background.png",
+ "assets/music.wav",
+ }
+
+ -- Start loading with progress
+ RL.BeginAssetLoading(#assets)
+
+ -- Load each asset
+ for i, path in ipairs(assets) do
+ RL.UpdateAssetLoading(path)
+
+ -- Your loading code
+ if path:match("%.png$") then
+ textures[i] = RL.LoadTexture(path)
+ elseif path:match("%.wav$") then
+ sounds[i] = RL.LoadSound(path)
+ end
+ end
+
+ -- Finish loading
+ RL.EndAssetLoading()
+end
+Features:
+See ASSET_LOADING.md for full documentation.
+Bundle all your Lua code into the executable for easy distribution:
+# Copy Lua files to build directory
+cd build
+copy ..\your_game\*.lua .
+
+# Build with embedding
+cmake .. -DEMBED_MAIN=ON
+cmake --build . --config Release
+Result: Single executable with all Lua code embedded!
+Package images, sounds, fonts, and other assets into your executable:
+# Create assets folder and copy files
+cd build
+mkdir assets
+copy ..\your_game\assets\* assets\
+
+# Build with embedding
+cmake .. -DEMBED_ASSETS=ON
+cmake --build . --config Release
+-- Works in both development and release
+playerImg = RL.LoadTexture("assets/player.png")
+music = RL.LoadSound("assets/music.wav")
+See EMBEDDING.md for full documentation.
+By default, ReiLua runs without a console window for a clean user experience. Enable it for debugging:
+# Show console for debugging
+ReiLua.exe --log
+
+# Combine with other options
+ReiLua.exe --log --no-logo
+ReiLua.exe --log path/to/game
+This shows:
+One-command builds for development and release:
+Development Build (Fast Iteration):
+# Windows
+scripts\build_dev.bat
+
+# Linux/Unix
+chmod +x scripts/build_dev.sh
+scripts/build_dev.sh
+Release Build (Distribution):

+Some objects allocate memory that needs to be freed when no longer needed. By default, objects like Textures are unloaded by the Lua garbage collector. However, it's generally recommended to handle this manually in more complex projects:
+RL.SetGCUnload()
+ReiLua can run single Lua files using interpreter mode:
+ReiLua -i hello.lua
+The given file will be called with dofile.
Generate API.md and ReiLua_API.lua from the build folder:
+ReiLua -i ../tools/docgen.lua
+You'll need to statically link Raylib and Lua to create the executable. This simplifies distribution, especially on Linux where different distros use different library versions.
+# Download Raylib source
+# Run w64devkit.exe and navigate to raylib/src
+cd raylib/src
+mingw32-make
+
+# Copy libraylib.a to ReiLua/lib folder
+copy libraylib.a path\to\ReiLua\lib\
+Download Lua source from https://github.com/lua/lua
+Modify Lua's makefile:
+# Change this:
+MYCFLAGS= $(LOCAL) -std=c99 -DLUA_USE_LINUX -DLUA_USE_READLINE
+# To this:
+MYCFLAGS= $(LOCAL) -std=c99
+
+# Comment out or remove:
+MYLIBS= -ldl -lreadline
+Build:
+# In w64devkit, navigate to Lua folder
+mingw32-make
+
+# Copy liblua.a to ReiLua/lib folder

+The loading system makes your game feel polished with just a few lines of code!
+ReiLua includes a built-in splash screen system that displays splash screens before your game loads. This gives your game a polished appearance right from startup.
+When you run your ReiLua game, it automatically shows two splash screens in sequence:
+1. Custom Text - Clean, bold text on Raylib red background (similar to Squid Game style) 2. "Made using" - Text with Raylib and ReiLua logos displayed side-by-side
+Each splash screen:
+The logo images are always embedded into the executable in both development and release builds. This means:
+The splash screens display before your game's asset loading begins. This means:
+1. User starts your game 2. Splash screens play (~8 seconds) 3. Your RL.init() function runs 4. Asset loading with progress indicator (if you use it) 5. Your game starts
This creates a smooth, polished startup experience.
+During development, you often need to test your game repeatedly. Waiting for splash screens every time can slow down your workflow. Use the --no-logo flag to skip them:
# Windows
+ReiLua.exe --no-logo
+
+# Linux/Mac
+./ReiLua --no-logo
+
+# With other options
+ReiLua.exe --log --no-logo
+./ReiLua --no-logo path/to/game/
+--no-logo flag only works in development. In release builds, users should see the full splash screen sequence.
+The splash screen system is implemented in C and runs before any Lua code executes:
+1. Logo Embedding: During build, scripts/embed_logo.py converts PNG files to C byte arrays 2. Initialization: Before calling RL.init(), the engine initializes splash screens 3. Display Loop: A dedicated loop handles timing, fading, and rendering 4. Cleanup: After completion, resources are freed and Lua code begins
src/splash.c - Splash screen implementationinclude/splash.h - Header filescripts/embed_logo.py - Python script to embed logo imageslogo/raylib_logo.png - Raylib logo (embedded)logo/reilua_logo.png - ReiLua logo (embedded)The CMakeLists.txt automatically:
+1. Runs scripts/embed_logo.py during build 2. Generates embedded_logo.h with logo data 3. Defines EMBED_LOGO flag 4. Compiles splash.c with the project
No manual steps required - it just works!
+To change the default text to your studio name:
+1. Open src/splash.c 2. Find the splash drawing function 3. Change the text line:
const char* text = "YOUR STUDIO NAME";
+ 4. Rebuild the project
+Note: Use ALL CAPS for the Squid Game-style aesthetic. +To use different logos:
+1. Replace logo/raylib_logo.png and/or logo/reilua_logo.png with your images 2. Recommended size: 256x256 or smaller (logos are auto-scaled to max 200px) 3. Format: PNG with transparency support 4. Rebuild the project - logos will be automatically embedded
To adjust how long each screen displays:
+1. Open src/splash.c 2. Modify these constants at the top:
#define FADE_IN_TIME 0.8f // Seconds to fade in
+ #define DISPLAY_TIME 2.5f // Seconds to display fully
+ #define FADE_OUT_TIME 0.8f // Seconds to fade out
+ 3. Rebuild the project
+If you don't want any splash screens:
+1. Open src/main.c 2. Find this block:
/* Show splash screens if not skipped */
+ if ( !skip_splash ) {
+ splashInit();
+ // ... splash code ...
+ splashCleanup();
+ }
+ 3. Comment out or remove the entire block 4. Rebuild the project
+Here's what a typical game startup looks like with everything enabled:
+ReiLua.exe MyGame/
+User Experience: 1. Splash Screen 1 (4.1 seconds)
+2. Splash Screen 2 (4.1 seconds)
+3. Asset Loading (varies)
+4. Game Start
+1. Keep --no-logo for Development: Always use --no-logo during active development 2. Test Without Flag: Occasionally test without --no-logo to ensure splash screens work 3. Customize for Your Studio: Change the text and logos to match your branding 4. Consider Total Time: Splash (~8s) + Loading (varies) = Total startup time 5. Optimize Loading: Keep asset loading fast to maintain a good first impression

+logo/reilua_logo.png โ Studio logo (keep ReiLua logo for credit)
+cd build
+cmake ..
+cmake --build . --config Release
+Result: SpaceQuest.exe with all your custom branding!
If you want to completely remove ReiLua references:
+1. Open src/splash.c 2. Find drawMadeWithSplash() function 3. Comment out or modify the function to only show your logo
1. Open src/main.c 2. Find the splash screen loop 3. Modify to only call your custom splash
After making any customizations:
+# Clean build (recommended after customizations)
+cd build
+rm -rf * # Or: rmdir /s /q * on Windows
+cmake ..
+cmake --build . --config Release
+
+# Test with console
+YourGame.exe --log
+
+# Test production mode
+YourGame.exe
+Verify:
+Before releasing your game:
+1. Consistent Branding: Use the same colors, fonts, and style across splash screens, loading screen, and in-game UI
+2. Icon Quality: Invest time in a good icon - it's the first thing users see
+3. Version Management: Update version numbers for each release
+4. Legal Info: Always include proper copyright and attribution
+5. Test Everything: Test your branded executable on a clean system
+6. Keep Credits: Mention Raylib and ReiLua in your game's credits screen

+Now your ReiLua executable is fully branded and ready to represent your game!
+This guide explains how to set up autocomplete, type hints, and documentation for ReiLua in Zed Editor.
+---
+Zed uses the Lua Language Server (LuaLS) for Lua support. ReiLua includes tools/ReiLua_API.lua with LuaLS annotations.
Zed should automatically install LuaLS when you open a Lua file. If not:
+1. Open Zed 2. Go to Extensions (Cmd/Ctrl + Shift + X) 3. Search for "Lua" 4. Install the Lua extension
+Create a .luarc.json file in your project root:
{
+ "runtime.version": "Lua 5.4",
+ "workspace.library": [
+ "${3rd}/luassert/library",
+ "${3rd}/busted/library"
+ ],
+ "completion.enable": true,
+ "diagnostics.globals": [
+ "RL"
+ ],
+ "workspace.checkThirdParty": false
+}
+Copy tools/ReiLua_API.lua to your game project folder:
# From ReiLua directory
+cp tools/ReiLua_API.lua /path/to/your/game/project/
+Or on Windows:
+Copy-Item tools/ReiLua_API.lua "C:\path\to\your\game\project\"
+For better organization, create a library directory:
+your-game/
+โโโ main.lua
+โโโ .luarc.json
+โโโ .lua/
+ โโโ tools/ReiLua_API.lua
+Update .luarc.json:
{
+ "runtime.version": "Lua 5.4",
+ "workspace.library": [".lua"],
+ "completion.enable": true,
+ "diagnostics.globals": ["RL"],
+ "workspace.checkThirdParty": false
+}
+---
+To make ReiLua API available for all projects:
+1. Create directory: %USERPROFILE%\.luarocks\lib\lua\5.4\ 2. Copy tools/ReiLua_API.lua to this directory 3. Add to global LuaLS config:
%APPDATA%\Zed\settings.json or via Zed settings
+{
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.workspace.library": [
+ "C:\\Users\\YourName\\.luarocks\\lib\\lua\\5.4"
+ ],
+ "Lua.diagnostics.globals": ["RL"]
+ }
+ }
+ }
+}
+1. Create directory: ~/.lua/reilua/ 2. Copy tools/ReiLua_API.lua to this directory 3. Update Zed settings:
{
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.workspace.library": [
+ "~/.lua/reilua"
+ ],
+ "Lua.diagnostics.globals": ["RL"]
+ }
+ }
+ }
+}
+---
+Create a .zed/settings.json in your project: > Note There is a sample zed settings json file in the repo root (zed.sample.settings.json)
{
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.runtime.version": "Lua 5.4",
+ "Lua.workspace.library": [
+ "."
+ ],
+ "Lua.completion.enable": true,
+ "Lua.completion.callSnippet": "Replace",
+ "Lua.completion.displayContext": 3,
+ "Lua.diagnostics.globals": [
+ "RL"
+ ],
+ "Lua.hint.enable": true,
+ "Lua.hint.paramName": "All",
+ "Lua.hint.setType": true
+ }
+ }
+ }
+}
+---
+Create a test file test.lua:
function RL.init()
+ -- Type "RL." and you should see autocomplete
+ RL.SetWindowTitle("Test") -- Should show documentation
+
+ local color = RL.RED -- Should autocomplete color constants
+
+ -- Hover over functions to see documentation
+ RL.DrawText("Hello", 10, 10, 20, color)
+end
+
+function RL.update(delta)
+ -- 'delta' should show as number type
+end
+If autocomplete works, you should see:
+RL.---
+In Zed settings:
+{
+ "inlay_hints": {
+ "enabled": true
+ },
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.hint.enable": true,
+ "Lua.hint.paramName": "All",
+ "Lua.hint.setType": true,
+ "Lua.hint.paramType": true
+ }
+ }
+ }
+}
+This will show:
+Add these to suppress common false positives:
+{
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.diagnostics.disable": [
+ "lowercase-global",
+ "unused-local",
+ "duplicate-set-field",
+ "missing-fields",
+ "undefined-field"
+ ],
+ "Lua.diagnostics.globals": ["RL"]
+ }
+ }
+ }
+}
+Common warnings and what they mean:
+lowercase-global - Using global variables with lowercase names (RL is intentional)unused-local - Local variables that aren't usedduplicate-set-field - Redefining functions (callback functions are expected to be redefined)missing-fields - Table fields that might not existundefined-field - Accessing fields that aren't documented> Note: The tools/ReiLua_API.lua file now uses type annotations instead of function definitions for callbacks to prevent duplicate warnings.
---
+Duplicate field 'init'. (Lua Diagnostics. duplicate-set-field)
+Why: The tools/ReiLua_API.lua file previously defined callback functions as empty function definitions. When you define them in your main.lua, LSP sees it as redefining the same field.
+Solution: The latest tools/ReiLua_API.lua now uses type annotations instead:
+-- Old way (caused warnings)
+function RL.init() end
+
+-- New way (no warnings)
+---@type fun()
+RL.init = nil
+Fix Steps: 1. Update tools/ReiLua_API.lua - Copy the latest version from the repository 2. Or add to diagnostics.disable in your configuration:
{
+ "diagnostics.disable": ["duplicate-set-field"]
+ }
+ 3. Restart Zed to reload the configuration
+Benefits of the new approach:
+---
+1. Restart Zed after configuration changes 2. Check LSP Status: Look for Lua Language Server in bottom-right status bar 3. Verify File Location: Ensure tools/ReiLua_API.lua is in the workspace 4. Check Console: Open Zed's log to see LSP errors
If the language server is slow:
+{
+ "lsp": {
+ "lua-language-server": {
+ "settings": {
+ "Lua.workspace.maxPreload": 2000,
+ "Lua.workspace.preloadFileSize": 1000
+ }
+ }
+ }
+}
+Ensure hover is enabled:
+{
+ "hover_popover_enabled": true
+}
+---
+You can extend tools/ReiLua_API.lua with your own game types:
---@class Player
+---@field x number
+---@field y number
+---@field health number
+
+---@class Enemy
+---@field x number
+---@field y number
+---@field damage number
+
+-- Your game globals
+---@type Player
+player = {}
+
+---@type Enemy[]
+enemies = {}

+Happy Coding!
+Complete function reference.
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.
RL.BeginAssetLoading( int totalAssets )Initialize asset loading progress tracking and show the loading screen. This displays a beautiful loading UI with progress bar and asset names.
+Parameters:
+totalAssets (integer) - Total number of assets to loadExample:
+RL.BeginAssetLoading(10) -- We're loading 10 assets
+Features:
+RL.UpdateAssetLoading( string assetName )Update loading progress for the current asset. Call this after each asset is loaded to update the progress bar and display.
+Parameters:
+assetName (string) - Name of the asset currently being loadedExample:
+RL.UpdateAssetLoading("player.png")
+-- Load the asset here
+playerTexture = RL.LoadTexture("assets/player.png")
+Notes:
+RL.EndAssetLoading()Finish asset loading and hide the loading screen. Call this after all assets have been loaded.
+Example:
+RL.EndAssetLoading()
+Complete Example:
+function RL.init()
+ local assets = {}
+ local assetsToLoad = {
+ "assets/player.png",
+ "assets/enemy.png",
+ "assets/background.png",
+ "assets/music.wav",
