# Setting Up The Scene

To start building your 3D city, you’ll need to create a project folder, set up a new scene, and add the necessary Easy Grid Builder Pro 2 prefabs. Let’s walk through the process step-by-step.

***

## <mark style="color:green;">Creating the Project Structure</mark>

First, organize your project by creating a new folder and a demo scene.

1. **Create a New Folder:**
   * Create a folder in your Unity project for this tutorial.
   * Example name: `3D City Builder Tutorial Demo`
2. **Create a New Scene:**
   * Inside this folder, create a new scene for your demo.
   * Example name: `3D City Builder Tutorial Demo Scene`

***

## <mark style="color:green;">Adding Grid Manager Prefab</mark>

Next, add the core Easy Grid Builder Pro 2 prefabs to your scene.

* Locate the **Grid Managers** prefab in:\ <mark style="color:purple;">**Assets/SoulGames/Easy Grid Builder Pro 2/Prefabs/Grid Managers.prefab.**</mark>
* Drag and drop the prefab into your scene. This prefab manages all grid systems in your project.

**Important:** After adding the prefab:

1. Right-click on the **Grid Managers** object in the **Hierarchy**.
2. Select <mark style="color:purple;">**Prefab > Unpack Completely**</mark> to unpack the prefab.

{% hint style="info" %}
If your scene already includes an **EventSystem** GameObject, you’ll find another one in the **Grid Managers** prefab. Remove either the existing **EventSystem** or the one inside **Grid Managers** to avoid conflicts.
{% endhint %}

## <mark style="color:green;">Adding And Configuring Grid System</mark>

Now, let’s add and set up the grid system for your scene.

1. **Add the Grid Prefab:**
   * Locate the **EGB Pro 2 Grid XZ** prefab in:\ <mark style="color:purple;">**Assets/SoulGames/Easy Grid Builder Pro 2/Prefabs/EGB Pro 2 Grid XZ.prefab.**</mark>
   * Drag and drop it into your scene.
2. **Unpack the Prefab:**
   * Right-click on the prefab in the **Hierarchy** and select <mark style="color:purple;">**Prefab > Unpack Completely.**</mark>
3. **Grid Prefab Selection:**
   * Use the **EGB Pro 2 Grid XZ** prefab for 3D games, as it operates on the XZ plane.
   * The alternative **EGB Pro 2 Grid XY** prefab works on the XY plane but is otherwise identical.
4. **Generate a Unique Grid ID:**
   * After unpacking, locate the **Grid Unique ID** property in the **Core Grid Properties** section of the grid component.
   * Click the refresh button next to the property to generate a unique ID.
5. **Display the Grid in the Editor:**
   * Enable the **Update Grid In Editor** property (below the Grid Unique ID property) to preview the grid in the Unity Editor.

   * In the **Hierarchy**, delete the **Main Camera** object.
2. **Add the WASD Camera Controller Prefab:**
   * Navigate to:\ <mark style="color:purple;">**Assets/SoulGames/Easy Grid Builder Pro 2/Prefabs/Sample Camera Controller/WASD Camera Controller Prefab.prefab.**</mark>
   * Drag and drop the **WASD Camera Controller Prefab** into your scene.
3. **Unpack the Prefab:**
   * Right-click on the **WASD Camera Controller Prefab** in the **Hierarchy**.
   * Select <mark style="color:purple;">**Prefab > Unpack Completely.**</mark>
4. **Adjust the Camera’s Transform:**
   * Set the **Transform Position** values to:
     * **X:** 0
     * **Y:** -10
     * **Z:** 20
   * Set the **Transform Rotation** values to:
     * **X:** 0
     * **Y:** 0
     * **Z:** 0
   * Keep all other values at their default settings.
