The code below has a different behaviour depending on wether WebGL is activated or not. The browser with WebGL is centering the content whereas without WebGL it’s not because visibleOrigin is always at 0.0,0.0.
cc.EGLView.getInstance().setDesignResolutionSize(800,450, cc.RESOLUTION_POLICY.NOBORDER);
Also the following piece of code that can be found in the framework examples:
if(cc.RenderDoesnotSupport()){
//show Information to user
alert(“Browser doesn’t support WebGL”);
return false;
}
Is not doing anything when you are using a browser without WebGL.
