Question

在我的iOS游戏中，我希望英雄继续运行直到触摸屏幕并且英雄应该跳跃。所以我写道：
在.h文件中：

@interface Hero : CCSprite {
    CCSprite *_hero;
    id _keepRunning;
}
@property(nonatomic,retain) id keepRunning;

在.m文件中：

@synthesize keepRunning = _keepRunning;
-(id) init {
    _keepRunning = [CCRepeatForever actionWithAction:[CCAnimate actionWithSpriteSequence:@"heroRun%04d.png"
                                                                               numFrames:30
                                                                                   delay:0.02f
                                                                    restoreOriginalFrame:NO]];        
}

然后当游戏开始时，我调用run（）方法：

-(void) run {
    [_hero stopAllActions];
    [_hero runAction:_keepRunning];
    _heroState = RUNNING;
}

然后我发现在cocos2d v2.0中不推荐使用CCAnimate actionWithSpriteSequence: numFrames: delay: restoreOriginalFrame:。所以我的问题是，在cocos2d v2.0中，我该如何实现这个动画呢？也就是说，让我的英雄继续奔跑？谢谢！
编辑：
我试过这个：

-(CCAnimation*) getMyAnimationWithFramesName:(NSString*)nameFormat numFrames:(int)numFrames delay:(float)delay {
    NSMutableArray *frames = [[NSMutableArray alloc] init];
    for (int i = 1; i <= numFrames; i++) {
        NSString *frameName = [NSString stringWithFormat:nameFormat,i];
        [frames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:frameName]];
    }
    CCAnimation *ani = [CCAnimation animationWithSpriteFrames:frames delay:delay];
    return ani;
}

然后在init（）：

_keepRunning = [self getMyAnimationWithFramesName:@"heroRun%04d.png" numFrames:30 delay:0.02f];

并在run（）中：

[_hero runAction:[CCAnimate actionWithAnimation:_keepRunning]];

但它仍然无效。我该怎么办？

首先，您从＆＃39; http://www.codeandweb.com/texturepacker/download＆＃39;下载纹理。并制作p-List并在代码

下使用它

[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"AnimatedMan.plist"];

CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"AnimatedMan.png"];

[self addChild:spriteSheet];

收集帧列表（精灵）

NSMutableArray *walkAnimFrames = [NSMutableArray array];
for (int i=1; i<=6; i++) {
    [walkAnimFrames addObject:
     [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
      [NSString stringWithFormat:@"step0%d.png",i]]];
}

将动作交给精灵

CCAnimation *walkAnim = [CCAnimation animationWithSpriteFrames:walkAnimFrames delay:0.1f];

        manSprite=[CCSprite spriteWithSpriteFrameName:@"step01.png"];
        manSprite.position=ccp(winsize.width/2, winsize.height/2-40);

manSprite的Sprite RepeaetForever

id first=[CCSequence actions:[CCRepeatForever actionWithAction:
                                      [CCAnimate actionWithAnimation:walkAnim]],nil];

[manSprite runAction:first];

cocos2d精灵永远重复动画
