<h2 id="functions">Functions</h2>
<div class="apii"><code>function RL.init()</code></div>
<div class="apidesc"><p>This function will be called after window has been initialized. Should be used as the main init point.</p></div>
<div class="apii"><code>function RL.update( delta )</code></div>
<div class="apidesc"><p>This function will be called every frame during execution. It will get time duration from last frame on argument 'delta'</p></div>
<div class="apii"><code>function RL.draw()</code></div>
<div class="apidesc"><p>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.</p></div>
<div class="apii"><code>function RL.event( event )</code></div>
<div class="apidesc"><p>This function will be called on events input. Content of event table is determined by event type.</p></div>
<div class="apii"><code>function RL.log( logLevel, message )</code></div>
<div class="apidesc"><p>This function can be used for custom log message handling.</p></div>
<div class="apii"><code>function RL.exit()</code></div>
<div class="apidesc"><p>This function will be called on program close. Cleanup could be done here.</p></div>
<div class="apii"><code>function RL.config()</code></div>
<div class="apidesc"><p>This function will be called before InitWindow. Note! Only place where you should call InitWindow manually. Doesn't have OpenGL context at this point.</p></div>
<div class="apii"><code>function RL.load()</code></div>
<div class="apidesc"><p>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.</p></div>
<div class="apii"><code>function RL.unload()</code></div>
<div class="apidesc"><p>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.</p></div>
<h2 id="reilua-enhanced-functions">ReiLua Enhanced Functions</h2>
<div class="apii"><code>RL.BeginAssetLoading( int totalAssets )</code></div>
<div class="apidesc"><p>Initialize asset loading progress tracking and show the loading screen. This displays a beautiful loading UI with progress bar and asset names.</p>
<p>Parameters:</p>
<ul>
<li><code>totalAssets</code> (integer) - Total number of assets to load</li>
</ul>
<p>Example:</p>
<pre><code>RL.BeginAssetLoading(10) -- We're loading 10 assets
</code></pre>
<p>Features:</p>
<ul>
<li>Shows animated "LOADING..." text with dots</li>
<li>Displays progress bar with shimmer effect</li>
<li>Shows current asset name being loaded</li>
<li>Shows progress counter (e.g., "3 / 10")</li>
<li>1-bit pixel art aesthetic</li>
</ul></div>
<div class="apii"><code>RL.UpdateAssetLoading( string assetName )</code></div>
<div class="apidesc"><p>Update loading progress for the current asset. Call this after each asset is loaded to update the progress bar and display.</p>
<p>Parameters:</p>
<ul>
<li><code>assetName</code> (string) - Name of the asset currently being loaded</li>
</ul>
<p>Example:</p>
<pre><code>RL.UpdateAssetLoading("player.png")
-- Load the asset here
playerTexture = RL.LoadTexture("assets/player.png")
</code></pre>
<p>Notes:</p>
<ul>
<li>Automatically increments the loaded asset counter</li>
<li>Updates the loading screen UI</li>
<li>Shows the asset name on screen</li>
<li>Updates progress bar percentage</li>
</ul></div>
<div class="apii"><code>RL.EndAssetLoading()</code></div>
<div class="apidesc"><p>Finish asset loading and hide the loading screen. Call this after all assets have been loaded.</p>
<p>Example:</p>
<pre><code>RL.EndAssetLoading()
</code></pre>
<p>Complete Example:</p>
<pre><code>function RL.init()
local assets = {}
local assetsToLoad = {
"assets/player.png",
