Time for action – hitting the bird animation

Currently, when the hunter hits the bird, it just disappears from the screen. This does not look very realistic. I mean the hunter does not have some kind of disintegrator blaster or something like that, and the last time I checked the arrow does not work this way.

Let's fix this by adding falling and rotation animation:

1. Open the Bird.m file and add the following method right below the animateFly method:

   -(void)animateFall
   {
       CGPoint fallDownOffScreenPoint = 
         ccp(self.position.x, -self.boundingBox.size.height);
       
       CCActionMoveTo *fallOffScreen = 
         [CCActionMoveTo actionWithDuration:2.0f        
                         position:fallDownOffScreenPoint];
       
       CCActionRemove *removeWhenDone = [CCActionRemove action];
   
       CCActionSequence *fallSequence =
         [CCActionSequence actions: fallOffScreen,
                                    removeWhenDone,
                                    nil];
   
       [self runAction:fallSequence];
       ...
