SceneManager.LoadScene

参数

描述

Loads the scene by its name or index in Build Settings.

注意：在大多数情况下，为了避免在加载时出现暂停或性能中断现象， 您应该使用此命令的异步版，即： LoadSceneAsync。

When using this SceneManager.LoadScene, the loading does not happen immediately, it completes in the next frame. This semi-asynchronous behavior can cause frame stuttering and can be confusing because load does not complete immediately.

The given sceneName can either be the scene name only, without the .unity extension, or the path as shown in the BuildSettings window still without the .unity extension. If only the scene name is given this will load the first scene in the list that matches. If you have multiple scenes with same name but different paths, you should use the full path. Note that sceneName is case insensitive.

For opening scenes in the Editor see EditorSceneManager.OpenScene.

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // Only specifying the sceneName or sceneBuildIndex will load the scene with the Single mode
        SceneManager.LoadScene("OtherSceneName", LoadSceneMode.Additive);
    }
}

// Load an assetbundle which contains scenes.
// When the user clicks a button the first scene in the assetbundle is
// loaded and replaces the current scene.

public class LoadScene : MonoBehaviour
{
    private AssetBundle myLoadedAssetBundle;
    private string[] scenePaths;

    // Use this for initialization
    void Start()
    {
        myLoadedAssetBundle = AssetBundle.LoadFromFile("Assets/AssetBundles/scenes");
        scenePaths = myLoadedAssetBundle.GetAllScenePaths();
    }

            Debug.Log("scene2 loading: " + scenePaths[0]);
            SceneManager.LoadScene(scenePaths[0], LoadSceneMode.Single);
