Wrong Argument Number Count

I have completed my lens and everything runs properly in the preview and when I push it, but I cannot publish it because of the following error:

16:59:08 Error: Wrong argument number count, expected 1, got 2
at [anon] () native strict preventsyield
at onTap (BillboardSprite:34) preventsyield

I am using Travis Chen's Billboard Sprite script (in an empty object in the objects panel) which turns on a billboard with a video animation when tapped (https://lensstudio.zendesk.com/hc/en-us/community/posts/360000035023-Tap-to-Trigger-Billboard-and-Sound). Line 34 is "control.play(1, 0.0)" in the following:

[code]

// Play animation

var control = script.billboardSprite.getMaterial(0).getPass(0).baseTex.control;

if( control && control.play )

{

control.play(1, 0.0);

}

}

[/code]

On the sprite itself, I have the following script to prompt the video texture on the billboard to only play once:

[/code]

// -----JS CODE-----

// Plays a video texture

//@input Asset.Texture movie

 

var loops = 1;

 

var provider = script.movie.control;

provider.play(loops);

[/code]

I also have a tweenalpha on that billboard which is set to play automatically (no loop). I know I have everything assigned correctly in the inspector, since everything runs perfectly, so I assume it may just be an issue with the BillboardSprite code - which I haven't edited in any way.

I am willing to privately share my file if necessary! Thanks!

    Hey Jessica,

    I created a private thread and share the fixed project files over there.

    But for anyone who has the same problem, The problem is for the video texture its the best to check the video state before playing the video.

    You can do it like this:

    var provider = script.meme.mainPass.baseTex.control;

    if ( provider.getStatus() != VideoStatus.Playing )

    {

          provider.play( -1 ); // -1 will play looped.

    }
    Hope this will help.
     
    Best,

    Hello Jessie,

    Can you replace the way you play your animated texture from what you have to this one and see if you can get it to working:

     

    //@input Component.SpriteVisual spriteVisual

var loops = 100;
var offset = 0.0;

var provider = script.spriteVisual.mainPass.baseTex.control;
provider.play(loops, offset);

    In this way all you need to do is to assign your animated texture to the sprite and then assign the sprite to this script.

    Hope this will help you to fix the problem

    Amir - that would be replacing the following script, correct?

     

    // -----JS CODE-----

    // Plays a video texture

    //@input Asset.Texture movie

     

    var loops = 1;

     

    var provider = script.movie.control;

    provider.play(loops);

     

    Also, that script is making me assign a sprite visual (which has to be a sprite object) and a scene object (which also has to be a sprite object). Do I have to assign the same sprite to both? The video is already assigned to the texture of that sprite, by the way. I tried assigning the same script to both spots but it would not run.

    Hey Jessie,

    No that's actually would be a replacing for your play animation code.

    Also can you please share your project file if it didn't help you to fix the problem.

    Best,

    Amir.

    Hi Amir, I'm also having a problem with this issue

    When I input my code

    // -----JS CODE-----

    // @input Component.SpriteVisual meme

     

    script.meme.enabled = true

    var provider = script.meme.mainPass.baseTex.control;

    provider.play(1,0);

     

    I also get the error

     

     Error: Wrong argument number count, expected 1, got 2
    at [anon] () native strict preventsyield
    at [anon] (Script:6) preventsyield

    when I change the play(1,0) to play(1) it works when I tap the preview, however it says "calling play from invalid state"

    I'm not sure how I can get the video texture to work with the script because I just want to play a video texture by tapping the screen.

    Thanks

    Hey Jessica,

    Your script looks fine but you can check if the file is animated texture then start to play it to avoid the error logs.

    In order to do that update your script to be like below:

    // @input Component.SpriteVisual meme

    if( script.meme )

    {

    script.meme.enabled = true;

    var isAnimated = !!script.meme.mainPass.baseTex.control.getDuration;

    if( isAnimated )

    {

    var provider = script.meme.mainPass.baseTex.control;

    provider.play( 1, 0 );

    }

    }
     
    Hope this will fix your problem.
    Cheers,
    Amir.

    Hi Amir,

    When I inputed that script the log said

     ReferenceError: identifier 'isAnimated' undefined
    at [anon] (Script:11) preventsyield

    I'm not sure what to do from there, 

    sorry for the trouble.

    Hey Jessica,

    Yes the link is now working but you need to send me the whole project folder not only the .lsproj file.

     

    Thanks,

    Amir.
