Time for action – adding birds

In this game, the hunter will hunt birds, so let's create a bird object by performing the following steps:

1. Open Xcode and create a new subgroup in the Resources group, next to the Hunter and the Backgrounds groups. Call this new group Birds.

2. Open the Chapter_04/Assets/Birds folder and drag all images into the new Birds group in Xcode. Make sure that copy option is checked.

3. Create a new Objective-C class in the GameObjects group. Name this class Bird and make it a subclass of CCSprite.

4. Open the Bird.h file and replace its contents with the following code:

   #import "CCSprite.h"
   
   typedef enum BirdType
   {
       BirdTypeBig,
       BirdTypeMedium,
       BirdTypeSmall
   } BirdType;
   
   
   @interface Bird : CCSprite
   
   
   @property (nonatomic, assign) BirdType birdType;
   
   -(instancetype)initWithBirdType:(BirdType)typeOfBird;
   
   @end

5. Open the Bird.m file and add the following implementation of the initWithBirdType: method listed:

   -(instancetype)initWithBirdType:(BirdType)typeOfBird
   {
       //1
   ...
