Question

I am having a problem with my cocos2d game that supports retina display. Everything used to work fine but now i am working on an update. In this update i have only added 3 new images (also in hd). I am using texture atlases made with zwoptex. the png’s generated are gameart.png and gameart-hd.png. I am loading the files using this code:

 CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
    [frameCache addSpriteFramesWithFile:@"gameart.plist"];

when getting any sprite i am using spriteWithFrameName: method. Everything used to work fine before (Even on iPhone 4) but now i am getting the following error only on iPhone 4:

cocos2d: CCSpriteFrameCache: Frame 'tilei.png' not found
*** Assertion failure in -[BoardTile initWithSpriteFrame:]

the file tilei is available in both gameart.png and gameart-hd.png (tilei.png and tilei-hd.png) and the plist files. i rechecked it a thousand times. what could be going wrong? notice that the error is not showing the -hd suffix even though its only occurring while running on iPhone 4.

Answer 1

You don’t need the suffix of -hd for the sprites inside the hd spritesheet.

It looks like you have:

• sd-spritesheet
  • image1.png
  • image2.png
  • etc.
• hd-spritesheet
  • image1-hd.png
  • image2-hd.png
  • etc.

You need:

• sd-spritesheet
  • image1.png
  • image2.png
  • etc.
• hd-spritesheet
  • image1.png
  • image2.png
  • etc.
