Uncaught TypeError: Cannot read property 'roundPixels' of undefined

[neonwarge04]

Here is my code:

 

      var screenSize = {width : 600 , height : 550};      var renderer = PIXI.CanvasRenderer(screenSize.width , screenSize.height);      // var assets = new PIXI.loaders.Loader();      // assets.add("_assets/textures/sprites.json");      // assets.once("complete" , function(){ new MainGameScene(renderer , screenSize); });      // assets.load();      document.body.appendChild(renderer.view);

What happens when I run this is that I am getting this error from the logs:
`Uncaught TypeError: Cannot read property 'roundPixels' of undefined` which happens at pixi.js: 12420

 

I don't understand if browser security also applies to CanvasRenderer? Please let me know if there is something I missed.

Thanks a lot!

You forgot to use the `new` operator.

Hi Xerver,

 

Thanks for your reply. I am afraid I tried what you said but I am still getting the same error. 

 

Thank you!

Hi,

I think I may solved it now!

I tried supplying the options parameter with `{}`, I debug the pixi.js lib and seeing the option parameter was null. I though the options parameter is optional so I always leave it out since it provides the default values anyways.

I don't know but I think it should check the option if it is null? I am not verbose in javascript so pardon my rough code

 

@pixi.js:12420

this.roundPixels = (options == null)? true : options.roundPixels === true;

Here is what it looks right now:

var renderer = new PIXI.CanvasRenderer(screenSize.width , screenSize.height, {});

Thanks!

What version of pixi are you using? I don't see anywhere that roundPixels is set from options in the source...

 

Please submit a running example.

Regarding the example, I just tried a super basic pixi.js, the ones you find from your own tutorials. I just replaced the autoDetectRenderer() with CanvasRenderer. The version I am using is from dev branch I think. Maybe it is causing this problem? This what the logs gave me:

Pixi.js 3.0.8-dev

Nevertheless, I have the error gone away now. 

Thank you!

You must've had something else going on, I tried to reproduce this in about 3 examples and never got it to happen.
