unity scene manager

 

Here’s a clean, production‑ready Scene Manager system for Unity that handles three scenes:

• Home
• Game
• End

It includes:

• A SceneLoader script
• Optional UI button hooks
• A recommended folder structure

Everything is ready to drop into your project.

🎮 1. Folder Structure (recommended)

Assets/
├── Scripts/
│   └── Systems/
│       └── SceneLoader.cs
├── Scenes/
│   ├── Home.unity
│   ├── Game.unity
│   └── End.unity

---

🧠 2. SceneLoader.cs (your main scene manager)

using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneLoader : MonoBehaviour
{
    public void LoadHome()
    {
        SceneManager.LoadScene("Home");
    }

    public void LoadGame()
    {
        SceneManager.LoadScene("Game");
    }

    public void LoadEnd()
    {
        SceneManager.LoadScene("End");
    }

    public void QuitGame()
    {
        Application.Quit();
#if UNITY_EDITOR
        UnityEditor.EditorApplication.isPlaying = false;
#endif
    }
}

✔ What this script does

• Loads scenes by name
• Works with UI buttons
• Includes a safe Quit function for both Editor and builds

---

🖱 3. Hooking it up to UI Buttons

1. Create a Canvas → Button
2. Add the SceneLoader script to an empty GameObject (e.g., SceneManager)
3. Select the button → OnClick()
4. Drag the SceneManager object into the slot
5. Choose the function:
   • SceneLoader.LoadHome()
   • SceneLoader.LoadGame()
   • SceneLoader.LoadEnd()

---

🧪 4. Example Flow

Home Scene

• “Play” button → LoadGame()

Game Scene

• When player dies or wins → call LoadEnd()

End Scene

• “Retry” → LoadGame()
• “Home” → LoadHome()

Using a UI Button to load scenes in Unity is simple once you know the flow. You connect a button’s OnClick() event to a function in your script that calls SceneManager.LoadScene(). Here’s the full process laid out cleanly so you can wire it up without confusion.

🎮 Step‑by‑Step: Make a Button Load a Scene

1️⃣ Create your scenes

Make sure your scenes exist and are added to Build Settings:

1. Go to File → Build Settings
2. Click Add Open Scenes for each scene
3. Ensure the names match exactly (e.g., "Home", "Game", "End")

Unity can only load scenes that appear in this list.

---

2️⃣ Create a SceneLoader script

This script contains the functions your button will call.

using UnityEngine;
using UnityEngine.SceneManagement;

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

Attach this script to an empty GameObject in your scene (e.g., SceneManager).

---

3️⃣ Add a UI Button

1. Right‑click in the Hierarchy → UI → Button
2. Unity creates a Canvas + EventSystem automatically
3. Select the Button in the Hierarchy

---

4️⃣ Connect the Button to the SceneLoader

With the Button selected:

1. Scroll to the Button (Script) component

2. Find the OnClick() list

3. Click the + button to add a new event

4. Drag your SceneManager GameObject (the one with the script) into the empty slot

5. In the dropdown, choose:

   SceneLoader → LoadSceneByName(string)
   

6. A text field appears — type the scene name exactly:

   • "Home"
   • "Game"
   • "End"

Example:
If this button should start the game, type:

Game

---

🧪 Example Setup

Home Scene

• Play button → loads "Game"

Game Scene

• Game Over trigger → loads "End"

End Scene

• Retry button → loads "Game"
• Home button → loads "Home"

---

🧠 Why this method is ideal

• You only need one function for all scenes
• Easy to reuse across menus
• Clean and scalable for bigger projects
