无法更新Microsoft AzureSpatialAnchor [英] Update a Microsoft AzureSpatialAnchor not possible

问题描述

我正在开发一个统一的应用程序，我正在使用天蓝色的空间锚点.我发现无法更新现有的cloudAnchor.我试过了:

I develop an unity application an I am working with azure spatial anchors. I found no possibility to update a already existing cloudAnchor. I tried this:

    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);
        }
    }

该方法的第一个调用正在工作.在天蓝色的云中创建了一个spartialAnchor.在第二个呼叫中，当我想更新锚点时，我首先git错误:

The first call of the method is working. A spartialAnchor in the azure cloud was created. In the second call when I want to update the anchor I first git the error:

InvalidOperationException:在将SpatialAnchor保存到云后，不能使用SpatialAnchor :: SetExpirationUtcTimeMS更改到期时间.目前不支持该功能.响应简历:. 08-18 01:07:09.845 31868 31927 E Unity:at 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

要摆脱它，我必须删除此行:

To get rid of it I had to remove this line:

cloudAnchor.Expiration = DateTimeOffset.Now.AddDays(7);

但是云锚的更新仍然无法正常进行.我收到此错误:

But the update of the cloud anchor is still not working. I get this error:

OnError-指定的空间锚已经与其他商店关联

OnError - The specified spatial anchor is already associated with a different store

我也尝试使用此行进行更新

I tried also to use this line for an update

await CloudManager.CreateAnchorAsync(cloudAnchor);

我收到此错误:

这时，我只看到删除azure的curent spaceAnchor并创建一个新选项的选项.这不是正确的方法.

At this moment I just see the option to delete the curent spatialAnchor in azure and create a new one. This can't be the correct approach.

更新锚点的正确方法是什么?

推荐答案

这个问题/问题已经提出过，所以我可以为您提供最新的答案.当前无法更新已经存在的锚点.您将需要删除旧的锚点并创建一个新的锚点.

This question/problem has been posed before, so I can update you on the answer. Currently there is no way to update an already existing anchor. You will need to delete the old anchor and create a new one.
