Creating the zombie class

As our zombie is going to perform several movements such as walk, run, or hit and it will have some attributes as the life points, we will create a class for it. Follow these steps:

1. Right-click on the Classes group in the project navigator and select New File….

2. Click on iOS | cocos2d v3.x | CCNode class.

3. Make this class a subclass of CCNode, call it Zombie, and click on Create.

Replace the contents of Zombie.h with:

#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "CCAnimation.h"

typedef enum {
    stateStill = 0,
    stateWalking,
    stateRunning,
    stateHitting
} ZombieStates;

@interface Zombie : CCNode {
}

@property (readwrite, nonatomic) int lifePoints;
@property (readwrite, nonatomic) ZombieStates *state;
@property (readwrite, nonatomic) CCSprite *zombieSprite;
@property (readonly, nonatomic) CCActionAnimate *actionStill;
@property (readonly, nonatomic) CCActionRepeatForever *actionWalk;
@property (readonly, nonatomic) CCActionRepeatForever...
