Cocos2d中的视网膜和非视网膜图形

Question

I have a game in iphone already developed one year back in older version of cocos2d.

Now i want to upgrade the game with both retina and non-retina graphics for all iphone3G,3GS and 4+ devices.

I have used many buttons and CCMenus how can i handle them in code. Do i have to write conditions for every graphic?

Any help or tutorial?

Thanks in advance

Answer 1

No, you dont need to do the conditional coding.... You can have the retina display support bye either un-commenting or adding the below code into your appDelegate.m/.mm file in the applicationDidFinishLaunching

    if( ! [director enableRetinaDisplay:YES] )
    CCLOG(@"Retina Display Not supported");

Also you need to add "-hd" suffix image files for the retina display of the iPhone.

For cocos2d version 2 you need the "-ipad" & "-ipadhd" files to be present in your Resources folder.

To upgrade the cocos2d version you can follow the steps on this Link . But cocos2d version 2 supports 3GS and above iPhone.

Hope this information would help you.

Answer 2

As I know, the iOS will do this for you if you name the image file in a correctly way. ex: normal screen: banner.png Retina screen: banner@2x.png

The only thing you need to do is name the higher resolution image by a same name with the lower one and add subfix "@2x"
