<h1>Module <code>asset</code></h1>
<p>Asset manager.</p>
<p> Loads asset and cache them.</p>
<p> This only provides a streamlined way to handle asset, and doesn&rsquo;t handle the actual file loading/object creation itself; you are expected to provide your own asset loaders.</p>
<p> See the <a href="../modules/asset.html#Asset:__call">Asset:__call</a> method for more details on how assets are loaded. Hopefully this will allow you to use asset which are more game-specific than &ldquo;image&rdquo; or &ldquo;audio&rdquo;.</p>
<p> No dependencies.</p>

<dl class="function">

<strong>new (directory, loaders[, mode="auto"])</strong>
</dt>
<dd>
Create a new asset manager. </p>
<p> If the caching &ldquo;mode&rdquo; is set to auto (default), the asset manager will allow assets to be automaticaly garbage collected by Lua.</p>
<p> If set to &ldquo;manual&rdquo;, the assets will not be garbage collected unless the clear method is called.
&ldquo;manual&rdquo; mode is useful if you have assets that are particularly slow to load and you want full control on when they are loaded and unloaded (typically a loading screen).
</ul>
</ul>

<h3>Parameters:</h3>
<ul>
<li><span class="parameter">directory</span>
<span class="types"><a class="type" href="https://www.lua.org/manual/5.1/manual.html#5.4">string</a></span>
the directory in which the assets will be loaded
</li>
<li><span class="parameter">loaders</span>
<span class="types"><a class="type" href="https://www.lua.org/manual/5.1/manual.html#5.5">table</a></span>

</dt>
<dd>
<p>Load (and cache) an asset. </p>
<p> Asset name are similar to Lua module names (directory separator is the dot . and no extention should be specified).
To load an asset, ubiquitousse will try every loaders in the loader list with a name that prefix the asset name.
The first value returned will be used as the asset value.</p>
<p> Loaders are called with the arguments:</p>
<ul>
<li>path: the asset full path, except extension</li>
<li>&hellip;: other arguments given after the asset name. Can only be number and strings.</li>
</ul>
</ul>
</ul>

<h3>Parameters:</h3>
<ul>
<li><span class="parameter">assetName</span>
<span class="types"><a class="type" href="https://www.lua.org/manual/5.1/manual.html#5.4">string</a></span>
