<h1 id="getting-started-doorways">Getting Started: Doorways</h1>
<h2 id="creating-a-doorway">Creating a Doorway</h2>
<p>Now we need a way to tell DunGen where we want our doorways to be. To do this, we'll create another empty GameObject and call it “Doorway”. Be sure to parent it to your tile GameObject. Now we'll add a <code>Doorway</code> component to our new doorway: <code>Add Component &gt; DunGen &gt; Doorway</code></p>
<p><img align="left" alt="Doorway Placement" src="../assets/images/getting-started/doorway-placement.png" width="300" /></p>
<p>The doorway should be placed on the very edge of the tile with its local Z-axis (shown by the light blue line in the editor) pointing outwards.</p>
<div class="admonition note">
<p class="admonition-title">Working in 2D?</p>
<p>Make sure the door is correctly oriented to match your up-direction. The <strong>green line</strong> should point upwards.</p>
</div>
<div style="clear: both;"></div>

<details class="tip">
<summary>Can't see the doorway?</summary>
<p>If the doorway outline isn't visible, check that <strong>Gizmos</strong> are enabled in the Scene view. Look for this button: <img alt="Gizmos Button" class="off-glb" src="../assets/images/getting-started/gizmos-button.png" />. You may also need to expand the dropdown next to it and make sure the 'Doorway' checkbox is checked</p>
</details>
<p>Don't worry if the outline doesn't match the shape or size of your doorway. For the purpose of this tutorial, all that matters is that the doorway is centered correctly.</p>
<hr />
<h2 id="doorway-blockers">Doorway Blockers</h2>
<p>Right now, DunGen can connect Tiles using your doorway—but unused doorways would leave visible gaps in the dungeon walls. To prevent this, we’ll use <strong>Blockers</strong> to automatically fill in any unused doorways.</p>
<p>A blocker can be anything that visually closes off a doorway: a wall, debris, furniture, or even a sealed door.</p>
<p><img align="right" alt="Doorway Blocker" src="../assets/images/getting-started/doorway-blocker.png" width="300" /></p>
<ol>
<li>Create a new GameObject with a wall mesh (or whatever fits your aesthetic).</li>
<li>Position it to block the doorway.</li>
<li>Parent this blocker to the Doorway object.</li>
<li>In the Doorway component, expand the <strong>Blockers</strong> section.</li>
<li>Drag your blocker GameObject into the <strong>Scene Objects</strong> list.</li>
</ol>
<div style="clear: both;"></div>

<p>Now, when a doorway isn’t used during generation, the blocker will be shown. If the doorway is connected to another room, DunGen will automatically hide the blocker.</p>
<hr />
<h2 id="reusing-doorways">Reusing Doorways</h2>
<p>For easy reuse of our doorway, we can make it a prefab by dragging the GameObject into our project window. Now, any changes made will be reflected wherever we use our doorway prefab.</p>
<p>Once that's done, you can easily duplicate and reuse it for each of the remaining door gaps in your room:</p>
<ul>
<li>Drag the prefab into the scene, or</li>
<li>Select an instance and press <span class="keys"><kbd class="key-control">Ctrl</kbd><span>+</span><kbd class="key-d">D</kbd></span> to duplicate it</li>
</ul>
<p>Place a doorway at each of the gaps you left earlier.</p>
<hr />
<h2 id="recap">Recap</h2>
<p>At this stage, you should have:</p>
<ul class="task-list">
<li class="task-list-item"><label class="task-list-control"><input type="checkbox" disabled checked/><span class="task-list-indicator"></span></label> A simple room Tile</li>
<li class="task-list-item"><label class="task-list-control"><input type="checkbox" disabled checked/><span class="task-list-indicator"></span></label> A doorway placed at each entrance</li>
<li class="task-list-item"><label class="task-list-control"><input type="checkbox" disabled checked/><span class="task-list-indicator"></span></label> Each doorway containing a Blocker to fill in unused paths</li>
</ul>
<p>Here's what your setup should look like:</p>
<p><img alt="First Doorway - End Result" src="../assets/images/getting-started/first-doorway-end-result.png" /></p>
