# Setting up the Play Area

Configure your game’s play area by building one wall, then duplicating and positioning it to form a contained space.

In this tutorial, you’ll configure the play area for your game by:

- Creating and configuring one wall
- Duplicating and placing it to create a contained game area

## Materials

## 1. Overview

In this tutorial, you’ll configure the play area for your game by:

- Creating and configuring one wall
- Duplicating and placing it to create a contained game area

By the end of this tutorial, your game will look something like this:

## 2. Create a wall for the play field

Follow the video or text instructions below to create an empty parent GameObject, create a **Wall** child GameObject, set the **Wall** GameObjects’s transform values, and create a material for the **Wall** GameObject:

## 1\.  Create an empty parent GameObject.

- In the **Hierarchy** window, **right-click** > **Create Empty,** then rename it “Walls”.
- In the **Inspector** window, reset its **Transform** component.


## 2\.  Create a Wall child GameObject.

- In the **Hierarchy** window, **right-click** > **3D Object** > **Cube**, then rename it “West Wall”.
- In the **Inspector** window, reset the **West Wall** GameObject’s **Transform** component.
- Drag the **West Wall** GameObject onto the **Walls** GameObject. This makes the **West Wall** GameObject a child GameObject of the **Walls** GameObject.


## 3\.  Set the Wall’s transform values.

- Press the **F** key while the cursor is over the **Scene** view to frame the **West Wall** GameObject in the view.
- In the **Inspector** window, change the wall’s **Transform Scale** values to **X**=**0.5, Y**=**2.0, Z**=**20.5.**
- Set the **Transform's Position X** value to **-10**.
- This places the **West Wall** GameObject neatly on the edge of the play area.


## 4\.  Create a material for the walls.

- In the **Project** window, go to the **Materials** folder, then **right-click** > **Create** > **Material**.
- Rename this new material “Walls”.
- In the **Inspector** window, select the **Base Map** color field to open the color picker, then set the **RGB** values to **79**, **79**, **79** for a darker gray.
- Set the **Metallic Map** to **0** and change the **Smoothness** to **0.25**, for a matte finish.
- Drag the **Walls** material from the **Project** window onto the **West Wall** GameObject in the **Scene** view.

## 3. Finish the play field walls

Follow the video or text instructions below to create the East wall, the North wall, and the South wall, then test the game:

## 1\.  Create the East wall.

- Right-click the **West Wall** GameObject and select **Duplicate**.
- Rename the new GameObject “East Wall”.
- To reposition the wall, remove the negative sign in the **Position X** value of the **Transform** component.


## 2\. Create the North and South walls.

- Duplicate the **East Wall** GameObject and rename the duplicate “North Wall”.
- Set the **Rotation Y** value to **90**.
- Set its **Position X** value to **0** and its **Position Z** value to **10**.
- Duplicate **North Wall** GameObject, rename it “South Wall”, and set its **Position Z** value to **-10**.

## 3\.  Test the game.

- You should now be able to roll around and bump into the walls.
- If the ball is going through the walls, make sure that the IsTrigger property in the Collider component is disabled.
