Question

我正在Unity3d中创建一个场景，并将其资产插件导出为.unity3d文件。此外，我从我的服务器下载assetbudle到我的Android应用程序。场景被加载但我为立方体写的旋转脚本丢失了。我可以在我的Android应用程序中看到对象，我从哪里开始UnityPlayerActivity但对象不是旋转，因为我在Unity中可以看到

请你帮忙。

这是我用来在android

中加载资产的参考脚本

IEnumerator receive(string message)
 {
 // Download compressed scene. If version 5 of the file named "Streamed-Level1.unity3d" was previously downloaded and cached.
 // Then Unity will completely skip the download and load the decompressed scene directly from disk.
 var download = WWW.LoadFromCacheOrDownload(message,19);
 yield return download;
 // Handle error
 if (download.error != null)
 {
     Debug.LogError(download.error);
     yield break;
 }
 // In order to make the scene available from LoadLevel, we have to load the asset bundle.
 // The AssetBundle class also lets you force unload all assets and file storage once it is no longer needed.
 var bundle = download.assetBundle;
 sceneNames = bundle.GetAllScenePaths ();
 // Load the level we have just downloaded
 SceneManager.LoadScene(sceneNames[0]);
 }
}

从我的活动中我使用方法向UnityPlayerActivity发送消息以启动播放器

UnityPlayer.UnitySendMessage("Main Camera", "receive", "https://MyServer/Level5.unity3d");

缺少此行为的引用脚本

从编辑器中双击该错误，它将显示导致该错误的对象。删除附加到它们的所有脚本，然后手动将脚本附加回这些对象。这应该修复引用对象错误。

如果双击它们没有显示受影响的GameObjects，则选择每个GameObject并手动删除并重新附加附加到它们的每个脚本。从上到下和所有GameObjects执行此操作。这应该修复引用对象错误。

我已将脚本附加到实际正在旋转的对象Cube上我的对象

我认为您不了解UnityPlayer.UnitySendMessage功能。

第一个参数是脚本所在的GameObject的名称附于。
第二个参数是该脚本中函数的名称你想打电话。
第三个参数是要传递给您要调用的脚本中的函数的参数/参数。

你说脚本附加到Gamebject名为“Cube”。您必须将“Cube”而不是“Main Camera”作为UnityPlayer.UnitySendMessage函数中的第一个参数传递。请注意，这是区分大小写的。

UnityPlayer.UnitySendMessage("Cube", "receive", "https://MyServer/Level5.unity3d");

另外，我不知道是否可以从Java端调用协同程序函数，因为协同程序需要StartCoroutine才能运行。 我建议您调用void函数启动协程函数，如果这不起作用。

void receive(string message)
{
    StartCoroutine(receiveCOR(message));
}

IEnumerator receiveCOR(string message)
 {
 // Download compressed scene. If version 5 of the file named "Streamed-Level1.unity3d" was previously downloaded and cached.
 // Then Unity will completely skip the download and load the decompressed scene directly from disk.
 var download = WWW.LoadFromCacheOrDownload(message,19);
 yield return download;
 // Handle error
 if (download.error != null)
 {
     Debug.LogError(download.error);
     yield break;
 }
 // In order to make the scene available from LoadLevel, we have to load the asset bundle.
 // The AssetBundle class also lets you force unload all assets and file storage once it is no longer needed.
 var bundle = download.assetBundle;
 sceneNames = bundle.GetAllScenePaths ();
 // Load the level we have just downloaded
 SceneManager.LoadScene(sceneNames[0]);
 }
}
