<h1>Making a ScriptNode prefab<a class="headerlink" href="#making-a-scriptnode-prefab" title="Link to this heading"></a></h1>
<p>The power of the script nodes is that you can create prefabs of them. Prefabs are a central feature of the editor. You are used to create prefabs of your characters, game items, UI elements. Prefabs provide a flexible architecture (<a class="reference external" href="./prefab-nested.html">nested prefabs</a>, <a class="reference external" href="./prefab-variant.html">prefab variants</a>, <a class="reference external" href="./prefab-user-properties.html">prefab properties</a>, <a class="reference external" href="./prefab-instance-children.html">appendable prefabs</a>) for creating reusable objects. And now it is also available for you to create the behaviors (or part of the beaviors) of your game.</p>
<p>You can create a script node prefab in the same way you create a prefab of a game object:</p>
<ol class="arabic simple">
<li><p><a class="reference external" href="./prefab-new-file.html">Create a prefab file</a>.</p></li>
<li><p><a class="reference external" href="./script-node-create.html">Add a script node to the scene</a>.</p></li>
</ol>
<p>If you add a script node prefab to a prefab scene, then it creates a prefab variant. It works the same as the game object prefabs. You can add custom properties.</p>
<p>If you are using the built-in <a class="reference external" href="./script-node-class.html">ScriptNode class</a> (what we recommend you to do), then you can implement any of the methods provided by that class, like the <strong>awake</strong> or <strong>execute</strong> methods.</p>
<p>The code generated for a script node prefab looks like this:</p>

<p>The above code is TypeScript. It is the implementation of the <strong>OnPointerDownScript</strong>, which is a <a class="reference external" href="./prefab-variant.html">prefab variant</a> of the <strong>OnEventScript</strong> prefab. Both prefabs are part of the <a class="reference external" href="script-node-basic-scripts-project.html">Basic Scripts project</a>.</p>
