我开发了一个统一的应用程序，我正在使用天蓝色的空间锚。我发现无法更新已经存在的 cloudAnchor。我试过这个：
protected virtual async Task SaveCurrentObjectAnchorToCloudAsync()
{
// Get the cloud-native anchor behavior
CloudNativeAnchor cna = cubeInstance.GetComponent<CloudNativeAnchor>();
// If the cloud portion of the anchor hasn't been created yet, create it
if (cna.CloudAnchor == null) {
cna.NativeToCloud();
}
// Get the cloud portion of the anchor
CloudSpatialAnchor cloudAnchor = cna.CloudAnchor;
// In this sample app we delete the cloud anchor explicitly, but here we show how to set an anchor to expire automatically
//cloudAnchor.Expiration = DateTimeOffset.Now.AddDays(7);
while (!CloudManager.IsReadyForCreate)
{
await Task.Delay(330);
float createProgress = CloudManager.SessionStatus.RecommendedForCreateProgress;
Debug.Log("create Progress");
Debug.Log(createProgress);
if(createProgress > 1)
{
createProgress = 1;
}
feedbackText.text = $"{ createProgress: 0 %}";
Debug.Log($"Move your device to capture more environment data: {createProgress:0%}");
}
bool success = false;
feedbackText.text = "Saving...";
try
{
if(currentCloudAnchor == null)
{
// Actually save
await CloudManager.CreateAnchorAsync(cloudAnchor);
} else {
await CloudManager.Session.UpdateAnchorPropertiesAsync(cloudAnchor);
}
// Store
currentCloudAnchor = cloudAnchor;
// Success?
success = currentCloudAnchor != null;
if (success && !isErrorActive)
{
// Await override, which may perform additional tasks
// such as storing the key in the AnchorExchanger
await OnSaveCloudAnchorSuccessfulAsync();
}
else
{
OnSaveCloudAnchorFailed(new Exception("Failed to save, but no exception was thrown."));
}
}
catch (Exception ex)
{
OnSaveCloudAnchorFailed(ex);
}
}
该方法的第一次调用正在工作。在蔚蓝的云中创建了一个 spartialAnchor。在第二次调用中，当我想更新锚时，我首先 git 错误：
InvalidOperationException：SpatialAnchor::SetExpirationUtcTimeMS 不能用于在 SpatialAnchor 保存到云端后更改过期时间。目前不支持该功能。请求简历：。回复简历：。08-18 01:07:09.845 31868 31927 E Unity：在 Microsoft.Azure.SpatialAnchors.NativeLibraryHelpers.CheckStatus（System.IntPtr 句柄，Microsoft.Azure.SpatialAnchors.status 值）[0x00109] 在 C:...\Assets\ AzureSpatialAnchors.SDK\Plugins\Common\AzureSpatialAnchorsBridge.cs:5381
为了摆脱它，我不得不删除这一行：
cloudAnchor.Expiration = DateTimeOffset.Now.AddDays(7);
但是云主播的更新还是不行。我收到此错误：
OnError - 指定的空间锚点已与不同的商店关联
我也尝试使用这条线进行更新
await CloudManager.CreateAnchorAsync(cloudAnchor);
我收到此错误：
无法保存锚点 System.InvalidOperationException: 。要求简历：。回复简历：。08-18 01:20:07.661 5849 5909 I Unity：在 Microsoft.Azure.SpatialAnchors.NativeLibraryHelpers.CheckStatus（System.IntPtr 句柄，Microsoft.Azure.SpatialAnchors.status 值）[0x00109] 在 C:...\Assets\ AzureSpatialAnchors.SDK\Plugins\Common\AzureSpatialAnchorsBridge.cs:5381 08-18 01:20:07.661 5849 5909 I Unity：在 Microsoft.Azure.SpatialAnchors.CloudSpatialAnchorSession+<>c__DisplayClass71_0.b__0 () [0x00001] 在 C:\Users\ ppelluda\Documents\Projects\shared-experiences-tests\Assets\AzureSpatialAnchors.SDK\Plugins\Common\AzureSpatialAnchorsBridge.cs:7162
此刻，我只看到删除 azure 中当前的 spatialAnchor 并创建一个新的选项。这不可能是正确的方法。
更新锚点的正确方法是什么？
