There are 3 sizes of images in my game. 1x , 2x, 3x.
In my previous game with cocos2d-x, I used 1x as design size, so I used 1x images in cocostudio.
Then I can just set different folder to load 2x or 3x images and setContentScaleFactor to make it right for larger screens.
But how to do the same thing in cocos creator? Canvas seems to only solve the aspect ratio issue, but not for different set of images.
What size should I put in cocos creator, 1x? 3x? or all?
