Simple and sweet Obj-C category for using Images.xcassets sprite atlas with cocos2d.

Basic usage

This category allows you to use Apples sprite atlas format with cocos2d. Which saves you from the trouble of relying on third-party tools to generate and maintain your sprite sheets.

Sprite atlases stored in .xcassets are generated when compiling the app and stored in the apps resource directory.

  1. Add a sprite atlas by choosing 'New sprite atlas' when clicking the plus icon in the Images.xcassets browser view.

  2. Add your images to the sprite atlas. Note: Sprite atlas seems to only support bitmap formats at the moment.

  3. #import CCSpriteFrameCache+XCAssetsCompatibility.h

  4. Load the sprite frames and the textures by calling: [[CCSpriteFrameCache sharedSpriteFrameCache] loadSpriteFramesForSpriteAtlasNamed:@"name_of_sprite_atlas"]

  5. Add sprites by referencing the sprite frames as they appear in the .xcassets collection. i.e: CCSprite *sprite = [CCSprite spriteWithSpriteFrame:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"sprite_name"]]
