Cocos2d-x multi-resolution adaptation

The 2d-x version is 2.1.1. The current project requires that iphone, iphone Retina, ipad, and ipad Retina have their own paths to store their own resources. In AppDelegate
The applicationDidFinishLaunching () function is set based on the screen resolution.

Static Resource iPhoneResource = {CCSizeMake (480,320), "iPhone "};

Static Resource iPhoneHDResource = {CCSizeMake (480*2,320*2), "iPhoneHD "};

Static Resource iPhoneTallerResource = {CCSizeMake (1136,640), "iPhoneTaller "};

Static Resource iPadResource = {CCSizeMake (1024,768), "iPad "};

Static Resource iPadHDResource = {CCSizeMake (2048,153 6), "iPadHD "};

Static CCSize designResolutionSize = CCSizeMake (480,320 );

Static CCSize designTallerResolutionSize = CCSizeMake (568,320 );

Static CCSize designIpadResolutionSize = CCSizeMake (512,384 );

}

 

After the path is set, the required resources will be searched in SearchPaths when you enter the game. Note that the resource files in each path are the same. You do not need to add the-HD suffix based on whether Retina is not available.
