Now that we have a way to load a large amount of images efficiently, we can go further using these images to animate our sprites.

An animation is the simulation of a movement by displaying sequences of static images that will make our brain think that it's looking at a smooth motion.

If you think about it, we already have the knowledge and the tools to create them because for this purpose, we need a sequence of static images that will be displayed in a loop that could be endless or not.

To begin, we need to import the CCAnimation class, so add the following code to the imports section in GameScene.h:

#import "CCAnimation.h"

Now let's declare a constant for the number of frames that will take part in the animation by adding the following lines to GameScene.m after the import section:

// Number of walk animation frames
const int NUM_WALK_FRAMES = 6;

This doesn't need an explanation, as it's just a constant declaration. Now add the following lines at the end of the init...
