cocos2d sprite 永远重复动画

cocos2d sprite repeat animation forever(cocos2d sprite 永远重复动画)

问题描述

在我的 iOS 游戏中，我希望英雄继续奔跑，直到屏幕被触摸并且英雄应该跳跃.所以我写:
在 .h 文件中:

In my iOS game, I hope the hero keep running until screen is touched and the hero should jump. So I write:
In .h file:

@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:

Then when the game starts, I call run () method:

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

然后我发现 CCAnimate actionWithSpriteSequence: numFrames: delay: restoreOriginalFrame: 在 cocos2d v2.0 中被弃用了.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！

我试过这个:

Then I found CCAnimate actionWithSpriteSequence: numFrames: delay: restoreOriginalFrame: is deprecated in cocos2d v2.0. So my question is, in cocos2d v2.0, how can I implement this animation? Namely, keep my hero running? Thank you!

I have tried this:

-(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()中:

Then in init ():

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

并在运行中():

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

但它仍然不起作用.我该怎么办?

But it still doesn't work. What should I do?

推荐答案

首先你从 'http://www.codeandweb.com/texturepacker/download'并制作 p-List 并在代码下方使用它

First of all you download Texture from 'http://www.codeandweb.com/texturepacker/download' and make p-List and use it below code

[[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]]];
}

将动作赋予精灵

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

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

Sprite RepeaetForever for manSprite

Sprite RepeaetForever for manSprite

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

[manSprite runAction:first];
