如何在 运行 命令行 (Unity3d) 的脚本中获取游戏对象（在场景中）

Question

我在 Unity3d 中为 运行 脚本使用命令行： "C:\Program Files (x86)\Unity\Editor\Unity.exe" -quit -batchmode -projectPath "path_to_project" -executeMethod Command.Do

在方法 "Do" 中：我尝试在场景中获取 GameObject：GameObject.Find("Automation")，但结果为 null(.

class Command
{
   static public void Do()
   {
    Debug.Log("Test");
    EditorUserBuildSettings.SwitchActiveBuildTarget(BuildTarget.Android);

    var scene = EditorBuildSettings.scenes[0];
    string name = scene.path.Substring(scene.path.LastIndexOf('/') + 1);
    name = name.Substring(0, name.Length - 6);

    SceneManager.LoadScene(0);

    var automationGo = GameObject.Find("Automation");
    System.Console.WriteLine("automationGo " + automationGo);
  }
}

Answer 1

我解决了： 相反 SceneManager.LoadScene(0) 需要使用：EditorSceneManager.OpenScene(scene.path);

万一有人从 Google 找到了这个帖子并想 运行 游戏来无头地测试东西（像我一样），这里是你需要的所有信息：

public class PlayTestsLoader : MonoBehaviour
{
    public static bool PlayTestsRunning = false;
    public static bool PlayTestsWantToStop = false;
    // Run with (note paths are Linux syntax - replace as needed)
    // ./Unity -projectPath ~/unityprojectname -executeMethod PlayTestsLoader.LoadTestScenes -logfile "~unityprojectname/logs.txt" -batchmode
    public static void LoadTestScenes()
    {
        try
        {
            EditorUserBuildSettings.SwitchActiveBuildTarget(BuildTargetGroup.Android, BuildTarget.Android); // Test Android code paths as if you were doing it manually in Editor
            EditorSceneManager.OpenScene($"Assets/Scenes/mainscene.unity"); // Load the scene in Editor - Not at play time!
            EditorApplication.isPlaying = true; // When this static method returns, setting isPlaying to true will start the game
            TestLog($"Entered playmode");
        }
        catch (Exception e)
        {
            TestLog($"Had exception {e}");
        }
        TestLog($"Complete PlayTestsLoader.LoadTestScenes");
    }

    static void TestLog(string log)
    {
        Debug.Log($"=== PlayTests === {log}");
    }

    public void Update()
    {
        if (PlayTestsRunning && PlayTestsWantToStop)
        {
            TestLog("ALL TESTS COMPLETED -- RETURNING 0");
            EditorApplication.Exit(0); // This will stop the game from running when you're done, and make the headless (invisible) editor exit
        }
    }

    public void OnEnable()
    {
        PlayTestsRunning = true;
        TestLog("PlayTestsLoader Monobehaviour started");
        StartCoroutine(PlayTestJourneyController());
    }
  
    IEnumerator PlayTestJourneyController()
    {
        yield return StartPvP();
        yield return SayHelloAfterPvP();
      
        PlayTestsWantToStop = true;
        yield return null;
    }
  
    IEnumerator StartPvP()
    {
        TestLog($"Hello from StartPvP");
        yield break;
    }
  
    IEnumerator SayHelloAfterPvP()
    {
        TestLog($"Hello from SayHelloAfterPvP");
        yield break;
    }
}

基本上，这可以让您设置所需的一切 - 您的更新循环、退出条件、任何协程等。
