SceneManager.Load

Learn to load a scene with SceneManager.LoadScene.

SceneManager and LoadScene

To switch scenes programmatically in Unity, the UnityEngine.SceneManagement namespace is imported. Calling SceneManager.LoadScene() with a scene name or build index transitions to the new scene.

using UnityEngine.SceneManagement;

// Loading a new scene by its asset name
SceneManager.LoadScene("Level1");

Executing this method reads the target scene asset from storage and activates it.

Scene Transition and Single Mode

By default, LoadScene operates in LoadSceneMode.Single mode. This mode wipes all GameObjects belonging to the current scene from memory before loading the new scene cleanly.

// Single scene transition by index (Single is default)
SceneManager.LoadScene(1, LoadSceneMode.Single);

This guarantees that residual enemies, projectiles, or obstacles from the prior level are completely purged.

Exercise Print target scene and mode info

Assign "Level1" to targetScene and "Single" to mode. Print Loading: Level1 | Mode: Single to the console.

Show example solution

using System;

class Program
{
    static void Main()
    {
        string targetScene = "Level1";
        string mode = "Single";
        Console.WriteLine("Loading: " + targetScene + " | Mode: " + mode);
    }
}
