<h1>Creating a Script Node<a class="headerlink" href="#creating-a-script-node" title="Link to this heading"></a></h1>
<p>A <a class="reference external" href="../scene-editor/script-node.html">ScriptNode</a> object shares a lot with the game objects, you can add it to the scene by dragging it from the <a class="reference external" href="../workbench/blocks-view.html">Blocks view</a> and dropping it on the scene:</p>
<img alt="Create script node from the blocks view." src="../_images/script-node-create-1-20230322.webp" />
<p>That action creates an instance of the <a class="reference external" href="./script-node-class.html">ScriptNode class</a> and adds it to the object selected in the scene. If no object is selected, then it adds the script node to the scene.</p>
<p>In addition to an instance of the <a class="reference external" href="./script-node-class.html">ScriptNode class</a>, you can add an instance of a <a class="reference external" href="./script-node-prefab.html">ScriptNode prefab</a>: select the <strong>Add Script</strong> option in the <strong>Scripting</strong> context menu or press the <strong>Add Script</strong> command (<code class="docutils literal notranslate"><span class="pre">U</span></code>).</p>
<img alt="Add Script command." src="../_images/script-node-add-script-dialog-20230627.webp" />
<p>It opens the <strong>Add Script</strong> dialog. There you can select the script you want to add:</p>
<img alt="The Add Script dialog." src="../_images/script-node-add-script-dialog.webp" />
<section id="browsing-the-script-nodes">
<h2>Browsing the Script Nodes<a class="headerlink" href="#browsing-the-script-nodes" title="Link to this heading"></a></h2>
<p>The <a class="reference external" href="../scene-editor/script-node.html">script nodes</a> are displayed in the <a class="reference external" href="../workbench/outline-view.html">Outline view</a>, below the parent object, or the scene:</p>
<img alt="Script nodes in the outline view." src="../_images/script-node-outline-20230322.webp" />
<p>Also, you can browse the scripts of an object by pressing the command <code class="docutils literal notranslate"><span class="pre">Shift+U</span></code>. The command is also available in the <strong>Scripting</strong> section of the context menu. That command opens the <strong>Browse Scripts</strong> dialog:</p>

<h2>Code generation of the creation of a script<a class="headerlink" href="#code-generation-of-the-creation-of-a-script" title="Link to this heading"></a></h2>
<p>When you add a <a class="reference external" href="../scene-editor/script-node.html">ScriptNode</a> to an object, it generates a code like this:</p>
<div class="highlight-javascript notranslate"><div class="highlight"><pre><span></span><span class="nx">editorCreate</span><span class="p">()</span><span class="w"> </span><span class="p">{</span>

<span class="w">    </span><span class="p">...</span>
<span class="p">}</span>
</pre></div>
</div>
<p>It is the code generated by the <a class="reference external" href="../scene-editor/scene-compiler.html">scene compiler</a> when you add a script node prefab. If you add an instance of the built-in ScriptNode, the code is similar, but using the <a class="reference external" href="./script-node-class.html">ScriptNode class</a>:</p>
<div class="highlight-javascript notranslate"><div class="highlight"><pre><span></span><span class="nx">editorCreate</span><span class="p">()</span><span class="w"> </span><span class="p">{</span>

<p>The <strong>ScriptNode</strong> class is not part of <a class="reference external" href="https://phaser.io">Phaser</a>, but it could be generated by Phaser Editor 2D. The next section is about it.</p>
