copied!<p>You can instantiate the Snake class file in your intro, using code like the following on frame 100:</p> <pre><code>var game:Snake = new Snake(); addChild(game); </code></pre> <p>assuming your document class is called <code>SnakeGame</code>. You may have to make a few changes in <code>SnakeGame</code> for this to work, however. The <code>stage</code> and <code>root</code> properties of <code>SnakeGame</code> will be null in the constructor when using this method. This is different behavior from it's was the document class (or placed directly on the stage) -- <code>stage</code> and <code>root</code> are already initialized. So if you do any actions to either <code>root</code> or <code>stage</code> in the constructor, you must change this or you will get an error. To fix this, listen for the <code>ADDED_TO_STAGE</code> event in <code>Snake</code>:</p> <pre><code>public function Snake() { addEventListener(Event.ADDED_TO_STAGE, onAddedToStage); } public function onAddedToStage(event:Event):void { removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage); // stage+root are now valid, put your init code here } </code></pre> <p>Alterantively, you could link the <code>Snake</code> class to an empty MovieClip symbol and place that directly on the stage on frame 100. First, create an empty MovieClip by going to Window->Library and clicking the +. In the Create New Symbol dialog, check "Export for ActionScript" and type in <code>Snake</code> in the Class field under Linkage. Now you can drag that MovieClip directly onto the stage on frame 100 and it hopefully will work without changes to the code.</p>
