<h2>setZBuffer</h2>

<H3>Syntax:</H3>

<P>
<pre class="syntax">setZBuffer (<i>zBufferFile</i>);</pre>
</P>

<H3>Purpose:</H3>

<P>
Sets a new z-buffer, loading it from the <i>zBufferFile</i> file.
</P>

<P>
If <i>zBufferFile</i> is NULL (or anything other than a file handle) the current z-buffer will be removed. With no z-buffer loaded, all characters will be visible wherever they are placed on the screen.
</P>

<P>
If <i>zBufferFile</i> is a valid file handle, the z-buffer to be loaded must be the same width and height as the current scene, as set using the <a href="setSceneDimensions.html">setSceneDimensions</a> function.
</P>

<H3>Return value:</H3>

<P>
No return value.
</P>
