Now we can turn our attention to our hero, the little spaceman. Let's start by looking through the
ERHero class.
Filename: ERHero.m
+(id)spriteWithSpriteFrameName:(NSString *)spriteFrameName {
return [[[self alloc] initWithSpriteFrameName:spriteFrameName] autorelease];
}
-(id) initWithSpriteFrameName:(NSString *)spriteFrameName {
if(self = [super initWithSpriteFrameName:spriteFrameName]) {
_state = kHeroFalling;
// Let the hero take 5 hits before death
heroHealth = 5;
}
return self;
}The ERHero class is a subclass of CCSprite class. Because we need a custom init method for the sprite, we have overridden the
spriteWithSpriteFrameName class method and the corresponding init method. As the _state variable might lead you to guess, the hero will be operating as a simple state machine. Let's see what states are valid:
typedef enum {
kHeroRunning = 1,
kHeroJumping,
kHeroInAir,
kHeroFalling...
