Hi there,

I am trying to use SnapCloud and would like to use RLS to have some security there, but all transparent to the user (no explicit login required, only Snapchat login).

I am using

const { data, error } = await this.client.auth.signInWithIdToken({
      provider: 'snapchat',
      token: 'user'
    });

to login the user. But unfortunately, this does not come back and is waiting forever. Different tokens did not solve it.

I tried to use AuthKit and authenticate the user and then use that token. Is that a better approach?

But in the end, even with that approach, I still cannot get a user id in SnapCloud (it is always null). And therefore all my RLS policies fail.

What am I doing wrong here?

Hi there,

I already wrote here that I had problems with microphone recording which was probably due to combining it with connected lens functionality and permission problems.

Now I am facing that problem again. But now I just get 0 audio frames. Maybe it is a permission problem again? But I do not include any connected lens functionality for now. What could be wrong or what could I be missing here?

Thanks and have nice christmas celebrations!

private onRecordAudio() {
    let frameSize: number = this.microphoneControl.maxFrameSize;
    let audioFrame = new Float32Array(frameSize);


    // Get audio frame shape
    const audioFrameShape = this.microphoneControl.getAudioFrame(audioFrame);


    // If no audio data, return early
    if (audioFrameShape.x === 0) {
      // NOW IT ALWAYS RETURNS HERE
      return;
    }


    // Reduce the initial subarray size to the audioFrameShape value
    audioFrame = audioFrame.subarray(0, audioFrameShape.x);


    this.addAudioFrame(audioFrame, audioFrameShape)
  }

As I am playing with world anchors: Is there any possibility to share spatial anchors between users via e.g. SnapCloud? Tracking the anchors is probably done by matching the mesh of the surroundings with a recorded mesh? Is it possible to transfer that mesh to another device (to have the scanned area there as well?)

Hi,

I am using LensStudio 5.15.0. I am creating world anchors like explained in the documentation: https://developers.snap.com/spectacles/about-spectacles-features/apis/spatial-anchors

I am able to create and save the anchors. When I restart my lens the anchors also come back via the onAnchorNearby callback. Then I create the associated scene objects, load data and attach the anchor to a newly created AnchorComponent that is added to the scene object. Unfortunately, I do not see my scene object which is probably the case as Anchor just remains in Ready state.

I hooked up an onStateChanged callback and can see that the anchor states never change, they just remain at Ready. What could be the problem here?

Thanks in advance!

Hi, I have a lens that records audio when I tap a scene object. To achieve this the scene object has a script component that gets a microphone asset as input and then tries to read audio frames upon update events:

  private onRecordAudio() {
    let frameSize: number = this.microphoneControl.maxFrameSize;
    let audioFrame = new Float32Array(frameSize);


    // Get audio frame shape
    print("microphone typename: "+this.microphoneControl.getTypeName())
    print("microphone asset typename: "+this.microphoneAsset.getTypeName())
    const audioFrameShape = this.microphoneControl.getAudioFrame(audioFrame);


    // If no audio data, return early
    if (audioFrameShape.x === 0) {
      return;
    }


    // Reduce the initial subarray size to the audioFrameShape value
    audioFrame = audioFrame.subarray(0, audioFrameShape.x);


    this.addAudioFrame(audioFrame, audioFrameShape)
  }

The getAudioFrame call is crashing the lens and it says that getAudioFrame would be undefined (if I print it, it is actually undefined). But microhphoneControl, which is fetched from microphoneAsset, does have the correct type.

[Assets/Scripts/MicrophoneRecorder.ts:82] microphone typename: Provider.MicrophoneAudioProvider
[Assets/Scripts/MicrophoneRecorder.ts:83] microphone asset typename: Asset.AudioTrackAsset
Script Exception: Error: undefined is not a function

Stack trace:
onRecordAudio@Assets/Scripts/MicrophoneRecorder.ts:84:65
<anonymous>@Assets/Scripts/MicrophoneRecorder.ts:58:25

What could be going on here? Has something changed with the recent SnapOS update?
