public static void LoadScene (int sceneBuildIndex, SceneManagement.LoadSceneMode mode= LoadSceneMode.Single);
public static void LoadScene (string sceneName, SceneManagement.LoadSceneMode mode= LoadSceneMode.Single);

参数

sceneName要加载的场景的名称或路径。
sceneBuildIndexBuild Settings 中要加载场景的索引。
mode允许您指定是否以累加方式加载场景。有关选项的更多信息,请参阅 LoadSceneMode

描述

按照 Build Settings 中的名称或索引加载场景。

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

使用 SceneManager.LoadScene 时,系统将不会立即加载场景,而是会在下一帧完成加载。这种半异步的行为可能会导致帧卡顿,并可能令人困惑,因为加载无法立即完成。

由于加载被设置为在下一个渲染帧中完成,调用 SceneManager.LoadScene 会强制完成之前的所有 AsynOperations,即使 AsyncOperation.allowSceneActivation 设置为 false 也一样。改用 LoadSceneAsync 可以避免此问题。

提供的 sceneName 可以只是场景名称(不包含 .unity 扩展名),也可以是 BuildSettings 窗口中显示的路径(仍然不包含 .unity 扩展名)。如果仅提供场景名称,此方法将加载场景列表中匹配的第一个场景。如果您有多个名称相同但路径不同的场景,应该使用完整路径。

请注意,除非您从 AssetBundle 加载场景,否则 sceneName 不区分大小写。

For opening Scenes in the Editor see EditorSceneManager.OpenScene. SceneA can additively load SceneB multiple times. The regular name is used for each loaded scene. If SceneA loads SceneB ten times each SceneB with have the same name. Finding a particular added scene is not possible.

using UnityEngine;
using UnityEngine.SceneManagement;

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.

using UnityEngine; using UnityEngine.SceneManagement;

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(); }

void OnGUI() { if (GUI.Button(new Rect(10, 10, 100, 30), "Change Scene")) { Debug.Log("Scene2 loading: " + scenePaths[0]); SceneManager.LoadScene(scenePaths[0], LoadSceneMode.Single); } } }

以下两个脚本示例显示 LoadScene 可以如何从 Build Settings 加载场景。LoadSceneA 使用要加载的场景的名称。LoadSceneB 使用要加载的场景的编号。这些脚本将协作。

LoadSceneA 文件。

// SceneA.
// SceneA is given the sceneName which will
// load SceneB from the Build Settings

using UnityEngine; using UnityEngine.SceneManagement;

public class LoadScenesA : MonoBehaviour { void Start() { Debug.Log("LoadSceneA"); }

public void LoadA(string scenename) { Debug.Log("sceneName to load: " + scenename); SceneManager.LoadScene(scenename); } }

LoadSceneB 文件。

// SceneB.
// SceneB is given the sceneBuildIndex of 0 which will
// load SceneA from the Build Settings

using UnityEngine; using UnityEngine.SceneManagement;

public class LoadScenesB : MonoBehaviour { void Start() { Debug.Log("LoadSceneB"); }

public void LoadB(int sceneANumber) { Debug.Log("sceneBuildIndex to load: " + sceneANumber); SceneManager.LoadScene(sceneANumber); } }

public static SceneManagement.Scene LoadScene (int sceneBuildIndex, SceneManagement.LoadSceneParameters parameters);
public static SceneManagement.Scene LoadScene (string sceneName, SceneManagement.LoadSceneParameters parameters);

参数

sceneName要加载的场景的名称或路径。
sceneBuildIndexBuild Settings 中要加载场景的索引。
parameters用于加载场景的各种参数。

返回

Scene 正在加载的场景的句柄。

描述

按照 Build Settings 中的名称或索引加载场景。

有关使用两个场景(名为 Scene1 和 /Scene2/)的示例。ExampleScript1.cs 用于 /scene1/,ExampleScript2.cs 用于 /scene2/。

using UnityEngine;
using UnityEngine.SceneManagement;

// This is scene1. It loads 3 copies of scene2. // Each copy has the same name.

public class ExampleScript1 : MonoBehaviour { private Scene scene;

private void Start() { var parameters = new LoadSceneParameters(LoadSceneMode.Additive);

scene = SceneManager.LoadScene("scene2", parameters); Debug.Log("Load 1 of scene2: " + scene.name); scene = SceneManager.LoadScene("scene2", parameters); Debug.Log("Load 2 of scene2: " + scene.name); scene = SceneManager.LoadScene("scene2", parameters); Debug.Log("Load 3 of scene2: " + scene.name); } }

Scene2:

using UnityEngine;

// create a randomly placed cube

public class ExampleScript2 : MonoBehaviour { private void Start() { GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube); cube.transform.position = new Vector3(Random.Range(-5.0f, 5.0f), 0.0f, Random.Range(-5.0f, 5.0f)); } }
