SceneManager.LoadSceneAsync

参数

返回

AsyncOperation 使用 AsyncOperation 确定操作是否已完成。

描述

在后台异步加载场景。

提供的场景名称可以是完成的场景路径（即 Build Settings 窗口中显示的路径），也可以只是场景名称。如果仅提供场景名称，此方法将加载匹配的场景列表中的第一个场景。如果您有多个名称相同但路径不同的场景，应该使用 Build Settings 中的完整场景路径。

Examples of supported formats:
"Scene1"
"Scene2"
"Scenes/Scene3"
"Scenes/Others/Scene3"
"Assets/scenes/others/scene3.unity"

注意：要加载场景的名称不区分大小写。

public class Example : MonoBehaviour
{
    void Update()
    {
        // Press the space key to start coroutine
        if (Input.GetKeyDown(KeyCode.Space))
        {
            // Use a coroutine to load the Scene in the background
            StartCoroutine(LoadYourAsyncScene());
        }
    }

    IEnumerator LoadYourAsyncScene()
    {
        // The Application loads the Scene in the background as the current Scene runs.
        // This is particularly good for creating loading screens.
        // You could also load the Scene by using sceneBuildIndex. In this case Scene2 has
        // a sceneBuildIndex of 1 as shown in Build Settings.

        AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Scene2");

        // Wait until the asynchronous scene fully loads
        while (!asyncLoad.isDone)
        {
            yield return null;
        }
    }
}
