一个精灵

Question

的Cocos2D两个动画动画我我的性格像：

-(void) createHero 
{ 


    _batchNode = [CCSpriteBatchNode batchNodeWithFile:@"Snipe1.png"]; 
    [self addChild:_batchNode]; 
    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"Snipe1.plist"]; 

    //gather list of frames 
    NSMutableArray *runAnimFrames = [NSMutableArray array]; 
    for(int i = 1; i <= 7; ++i) 
    { 
     [runAnimFrames addObject: 
     [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: 
     [NSString stringWithFormat:@"run000%d.png", i]]]; 
    } 

    //create sprite and run the hero 
    self.hero = [CCSprite spriteWithSpriteFrameName:@"run0001.png"]; 
    _hero.anchorPoint = CGPointZero; 
    _hero.position = self.heroRunningPosition; 

    //create the animation object 
    CCAnimation *runAnim = [CCAnimation animationWithFrames:runAnimFrames delay:1/30.0f]; 
    self.runAction = [CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:runAnim restoreOriginalFrame:YES]]; 

    [_hero runAction:_runAction]; 
    [_batchNode addChild:_hero z:0]; 
} 

这工作得很好了我的性格正在运行，但现在我想第二个动画，当他跳跃。目前，我让这样的：

-(void)changeHeroImageDuringJump 
{ 
    [_hero setTextureRect:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"run0007.png"].rect]; 
} 

但现在我想用第二PNG第二的plist，所以我得到了一个全新的动画当角色跳跃。我怎样才能实现呢？

在我的情况下，我实现了一个AnimatedSprite类来处理这个问题。这样一来，我想补充文件，像这样：

NSDictionary* anims = [NSDictionary dictionaryWithObjectsAndKeys: 
     @"Animations/Character/idle_anim.plist", @"Idle", 
     @"Animations/Character/walk_anim.plist", @"Walk", 
     @"Animations/Character/run_anim.plist", @"Run", nil]; 

CCNode* myNode = [[AnimatedSprite alloc] initWithDictionary:anims 
         spriteFrameName: @"character_idle_01.png" 
         startingIndex:@"Idle"]; 

更改动画很简单，只要：

[myNode setAnimation: @"Run"]; 

我的继承人履行这是.H

@interface AnimatedSprite : CCSprite 
{ 
    NSMutableDictionary* _spriteAnimations; 
    CCAction* _currentAnimation; 
    NSString* _currentAnimationName; 
    bool _initialized; 
} 
- (id) initWithTextureName:(NSString*) textureName; 
- (id) initWithArray: (NSArray*) animList spriteFrameName: (NSString*) startingSprite startingIndex: (int)startingIndex; 
- (id) initWithDictionary:(NSDictionary *)anims spriteFrameName:(NSString *)startingSprite startingIndex:(NSString *)startingAnim; 

- (void) addAnimation: (NSString*) animationName andFilename: (NSString*) plistAnim; 

- (void) setAnimationIndex: (int) index; 
- (void) setAnimation: (NSString*) animationName; 
@end 

这是.m

#import "AKHelpers.h" 

@implementation AnimatedSprite 

NSMutableDictionary* _spriteAnimations; 

- (id) initWithTextureName:(NSString*) textureName 
{ 
    CCTexture2D* texture = [[CCTextureCache sharedTextureCache] addImage:textureName]; 
    CCSpriteFrame* frame = [CCSpriteFrame frameWithTexture:texture rect: CGRectMake(0, 0, 1, 1)]; 

    if ((self=[super initWithSpriteFrame:frame])) 
    { 
     _currentAnimationName = nil;

     i++;

    if ((self = [super initWithSpriteFrameName:startingSprite]))

     NSDictionary* clip = [_spriteAnimations objectForKey: animationName];

     } 
    }

为跑步和跳跃创建两个不同的动画动作。根据需要运行这些操作。
