Scene transitions in Unity - Mini Project: Build & Apply

Scene transitions

📖 Scenario: You are making a simple game in Unity where the player can move from one scene to another by pressing a button. You want to learn how to switch scenes smoothly.

🎯 Goal: Build a Unity script that changes the scene when a button is pressed.

📋 What You'll Learn

Create a script to load scenes

Use UnityEngine.SceneManagement namespace

Add a public method to load a specific scene

Call the method on button press

💡 Why This Matters

🌍 Real World

Scene transitions are common in games and apps to move between levels, menus, or different parts of the experience.

💼 Career

Knowing how to manage scenes is essential for Unity developers working on interactive applications and games.

1

Create a new C# script with scene loading capability

Create a new C# script called SceneSwitcher. Inside it, add using UnityEngine.SceneManagement; at the top to access scene management features.

Unity

using UnityEngine;
// Your code here

Need a hint?

Remember to add using UnityEngine.SceneManagement; to use scene functions.

2

Add a public method to load a scene by name

Inside the SceneSwitcher class, add a public method called LoadSceneByName that takes a string parameter sceneName. Inside the method, call SceneManager.LoadScene(sceneName); to load the scene.

Unity

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneSwitcher : MonoBehaviour
{
    // Add public method LoadSceneByName below
    // Your code here
}

Need a hint?

The method should be public so you can call it from UI buttons.

3

Attach the script to a GameObject and connect to a UI button

In Unity Editor, attach the SceneSwitcher script to an empty GameObject. Then, create a UI Button and set its OnClick event to call LoadSceneByName on the GameObject, passing the exact scene name "NextScene" as argument.

Unity

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneSwitcher : MonoBehaviour
{
    public void LoadSceneByName(string sceneName)
    {
        SceneManager.LoadScene(sceneName);
    }
}

// Attach this script to a GameObject and connect the LoadSceneByName method to a UI Button's OnClick event with "NextScene" as parameter
// Your code here

Need a hint?

Use the Unity Editor to link the button's OnClick event to the script method with the scene name.

4

Test the scene transition by pressing the button

Run the game in Unity Editor. When you press the UI Button, the scene should change to NextScene. Use Debug.Log inside LoadSceneByName to print "Loading scene: " + sceneName before loading to confirm the method runs.

Unity

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneSwitcher : MonoBehaviour
{
    public void LoadSceneByName(string sceneName)
    {
        // Add Debug.Log here
        // Your code here
        SceneManager.LoadScene(sceneName);
    }
}

// Run and press the button to test scene change

Need a hint?

Check the Console window in Unity Editor to see the log message when you press the button.
