Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Copying the canvas HTML

Hey I am trying to copy the game that is displayed into the canvas in HTML. I know the canvas is displyed using WebGL so i thought using copyTexImage2D or toDataURL but neither seemed to work. This is how im am using the copyTexImage2D :

    var canvas2 = document.createElement('canvas');
     var context2 = canvas2.getContext("experimental-webgl"{preserveDrawingBuffer: true});
     var gl = document.getElementById("canvas").getContext("experimental-webgl",{preserveDrawingBuffer: true});
      var frameBufferObject = gl.createFramebuffer();
      var image = gl.copyTexImage2D(gl.TEXTURE_2D, 0, gl.RGBA, 0, 0, canvas.width, canvas.height, 0);
      context2.bindTexture(context2.TEXTURE_2D, image);
      context2.pixelStorei(context2.UNPACK_FLIP_Y_WEBGL, true);

I know that the image variable I create here is undefined if that has anything to do with going wrong.

Thanks for any help that you can provide.
