Since the Cocos2d-X 2.0 rc2 a lot of the initialisation has changed so this code works in Cocos2d-X 2.0.
First create a sprite sheet so we can load it in.
Once you have created the Sprite Sheet you will end up with a image file and plist.
mySprites.png
mySprites.plist
I like to name my sprites like this:
jumpAnimation_00
jumpAnimation_01
jumpAnimation_02
jumpAnimation_03
jumpAnimation_04
jumpAnimation_05
walkAnimations_00
walkAnimations_01
walkAnimations_02
walkAnimations_03
walkAnimations_04
walkAnimations_05
It makes creating the animations easier. My code below is depended on the above naming convention.
