LoadSceneMode.Additive

描述

将场景添加到当前加载的场景中。

LoadSceneMode.Additive 加载场景而不卸载当前加载的场景。附加加载的场景将显示在层级窗口中，而另一个场景处于活动状态。要卸载当前加载的场景之一，请参阅 SceneManager.UnloadSceneAsync 获取更多信息。
其他资源：SceneManager.LoadScene。
注意：如果您使用光探针，则必须之后运行 LightProbes.Tetrahedralize()。

public class Example : MonoBehaviour
{
    void OnGUI()
    {
        //This displays a Button on the screen at position (20,30), width 150 and height 50. The button’s text reads the last parameter. Press this for the SceneManager to load the Scene.
        if (GUI.Button(new Rect(20, 30, 150, 30), "Other Scene Single"))
        {
            //The SceneManager loads your new Scene as a single Scene (not overlapping). This is Single mode.
            SceneManager.LoadScene("YourScene", LoadSceneMode.Single);
        }

        //Whereas pressing this Button loads the Additive Scene.
        if (GUI.Button(new Rect(20, 60, 150, 30), "Other Scene Additive"))
        {
            //SceneManager loads your new Scene as an extra Scene (overlapping the other). This is Additive mode.
            SceneManager.LoadScene("YourScene", LoadSceneMode.Additive);
        }
    }
