unexpected Lens error - face trigger

Hi Zeno,

Happy to look into this issue for you. If you're comfortable sharing over the forum, could you send me the script and video asset you are using? If not comfortable sharing here, I can setup another thread for us to chat privately on.

Cheers,
Kaitlyn

Hi Kaitlyn, 

Thanks!  I used the standard FaceAnimTrigger script found in the template..  

Also while we're at it is there a maximum number of effects and script you can trigger with your face or tapping for example? 

this is the mp4 - https://we.tl/Qx6YTBeOZ9 

Thanks!

Hi Zeno,

I tried to open the video, but it says the page is not found. Can you resend?

Thanks,
Kaitlyn

Hi Zeno,

We actually don't need your video because I found the bug in the FaceAnimTrigger script. For video textures, the API is slightly different than the animated textures. It will report an error if you try to play the video while it is already playing. Also, it does not support playOffset. If you make these changes for the 2D Sprite portion in the FaceAnimTrigger Script: 

 for (var i = 0; i < script.play2dSprites.length; i++)
 {
    if (script.play2dSprites[i] 
        && script.play2dSprites[i].mainPass.baseTex
        && script.play2dSprites[i].mainPass.baseTex.control
        && script.play2dSprites[i].mainPass.baseTex.control.play)
     {
        script.play2dSprites[i].getSceneObject().enabled = true;

        //for video texture provider
        if (script.play2dSprites[i].mainPass.baseTex.control.getStatus){
        var videoStatus = script.play2dSprites[i].mainPass.baseTex.control.getStatus(); 
        if (videoStatus == VideoStatus.Playing){
            //stop the video if it is still playing 
            script.play2dSprites[i].mainPass.baseTex.control.stop();
        }
        script.play2dSprites[i].mainPass.baseTex.control.play(script.texturePlayCount);
      } 
    else{
        script.play2dSprites[i].mainPass.baseTex.control.play(script.texturePlayCount, script.texturePlayOffset);
       }
    }
 }

the lens error you were seeing before should be fixed! Let me know if you have any questions! 

Weeeew! Thank you so much!!  that did the trick :D I'll share when its finished
