Scene Creation and Management in Unity

📖 Scenario: You are building a simple Unity game where you need to create and manage multiple scenes. Each scene represents a different part of the game, such as a main menu, gameplay area, and game over screen.

🎯 Goal: Learn how to create scenes in Unity, set up scene management, and switch between scenes using code.

📋 What You'll Learn

Create scenes with exact names

Add a scene manager script

Use UnityEngine.SceneManagement namespace

Load scenes by name using code

Ensure scenes are added to build settings

💡 Why This Matters

🌍 Real World

Games and interactive apps often have multiple scenes for menus, gameplay, and other screens. Managing scenes lets you organize and switch between these parts smoothly.

💼 Career

Knowing scene management is essential for Unity developers working on games or simulations that require multiple screens or levels.

1

Create Scenes in Unity Editor

Create three scenes in your Unity project with the exact names MainMenu, Gameplay, and GameOver. Save each scene in the Assets/Scenes folder.

Unity

// Create three scenes named MainMenu, Gameplay, and GameOver in Assets/Scenes folder
// Your code here

Need a hint?

Use the Unity Editor's File > New Scene option to create new scenes. Save each scene with the exact names in the Assets/Scenes folder.

2

Add SceneManager Script and Import Namespace

Create a new C# script called SceneController. Inside it, add the line using UnityEngine.SceneManagement; at the top to enable scene management functions.

Unity

using UnityEngine;
// Add the SceneManagement namespace below
// Your code here

Need a hint?

At the top of your script, add using UnityEngine.SceneManagement; to access scene loading functions.

3

Write Method to Load Gameplay Scene

Inside the SceneController class, write a public method called LoadGameplayScene that uses SceneManager.LoadScene to load the scene named Gameplay.

Unity

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneController : MonoBehaviour
{
    // Write a public method LoadGameplayScene that loads the Gameplay scene
    // Your code here
}

Need a hint?

Define a public method that calls SceneManager.LoadScene("Gameplay") to switch scenes.

4

Add Scene to Build Settings and Finalize

Make sure all three scenes MainMenu, Gameplay, and GameOver are added to the Unity Build Settings under File > Build Settings. This allows them to be loaded at runtime.

Unity

// Add MainMenu, Gameplay, and GameOver scenes to Build Settings
// Your code here

Need a hint?

Open Build Settings in Unity and drag each scene from Assets/Scenes into the Scenes In Build list.
