Question

我有一个CCNode类，如下所示：

#import "CCAnimation.h"
#import "Gameplay.h"
#import "ZAFSingletonCenter.h"

@interface Gameplay ()
{
}

@property (nonatomic, strong) CCSprite *character;
@property (nonatomic, strong) CCAction *talkAction;

@end

@implementation Gameplay{

    NSMutableString *gesture;
    NSString *characterName;

    NSString *plist;
    NSString *gestureSprite;
    NSString *framefilename;

}

- (void)regresar {
    CCScene *mainScene = [CCBReader loadAsScene:@"MainScene"];
    [[CCDirector sharedDirector] replaceScene:mainScene];
}

- (void)didLoadFromCCB {


    ZAFSingletonCenter *temporal = [ZAFSingletonCenter sharedManager];
    characterName = temporal.personajeActual;

    gesture = [@"fotos" mutableCopy];

    plist = [NSString stringWithFormat:@"%@/%@.plist",characterName,gesture];
    gestureSprite = [NSString stringWithFormat:@"%@/%@.png",characterName,gesture];
    framefilename = [NSString stringWithFormat:@"%@/%@/%@_%@_",characterName,gesture,characterName,gesture];
    [self loadGesture:characterName withGesture:gesture];

    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:plist];
    CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:gestureSprite];
    [self addChild:spriteSheet];


    // *** This block should be moved outside the init or didLoadFromCCB
    // *** and to the moveCharacter:withGesture method... once I make it work

    NSMutableArray *actionFrames = [NSMutableArray array];
    for (int i=1001; i<=1020; i++) {
        [actionFrames addObject:
         [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:
          [NSString stringWithFormat:@"%@%d.png",framefilename,i]]];
        //NSLog(@"%@%d.png",_framefilename,i);
    }

    CCAnimation *gestureAction = [CCAnimation animationWithSpriteFrames:actionFrames delay:0.0666f];

    CGSize viewSize = [[CCDirector sharedDirector] viewSize];
    NSString *spriteCover = [NSString stringWithFormat:@"%@/%@/%@_%@_1011.png",characterName,gesture,characterName,gesture];
    self.character = [CCSprite spriteWithImageNamed:spriteCover];
    self.character.position = ccp(viewSize.width/2, viewSize.height/2);
    [spriteSheet addChild:self.character z:99];
    self.talkAction = [CCActionRepeatForever actionWithAction:
                       [CCActionAnimate actionWithAnimation:gestureAction]];


    [self.character runAction:self.talkAction];

    NSString *logMessage = self.character.debugDescription;
    NSLog(@"---> %@",logMessage);

    NSLog(@"---> %d",self.character.isRunningInActiveScene);

    NSString *gestureMessage = gestureAction.debugDescription;
    NSLog(@"---> %@",gestureMessage);

    NSString *actionMessage = self.talkAction.debugDescription;
    NSLog(@"---> %@",actionMessage);


    // *** ending the block to be taken to the moveCharacter:withGesture method

}


- (void)actionA {
    //testingButton A action
    NSLog(@"A");
    [self.character stopAction:self.talkAction];
}
- (void)actionB {
    //testingButton B action
    NSLog(@"B");
    [self.character runAction:self.talkAction];

}

@end

这应该在屏幕中间有一个动画角色，它在一个空项目上。但是当我在实际项目中包含它时，动画在我定义为“spriteCover”的帧上暂停。没有错误，只是没有播放动画。

我尝试使用 - （id）init而不是 - （void）didLoadFromCCB但是相同。我已经跟踪了几个步骤（你可以看到上面代码的日志部分），一切看起来都很好。以下是印刷线：

---> <CCSprite = 0x15693a50 | 
     Rect = (281.50,568.50,147.00,268.00) | 
     tag = (null) | atlasIndex = 0>

---> 0

---> <CCAnimation = 0x15692de0 | 
     frames=20, totalDelayUnits=20.000000, 
     delayPerUnit=0.066600, loops=1>

---> <CCActionRepeatForever = 0x15694470 | Tag = -1>

我添加了两个触发actionA和actionB的按钮，当在actionB上点击两次时，我收到错误（正如预期的那样），因为reason: 'runAction: Action already running'

我还尝试了this，this，this here和其他几个来源，但还没有解决问题。

Answer 1

我注意到您要针对多个用例回收CCAction talkAction。

每次在某事物上调用CCAction时，您都必须创建单独的runAction个实例。

解决此问题的一种简单方法是覆盖talkAction的getter以始终返回新的CCAction。

Answer 2

为了记录我的解决方案，我解决问题的方法是使用动画在CCScene之前获取UIViewController。我注意到在CCScene之后加载时一切都很完美但是在UIViewController之后加载时动画没有启动。

CCActionAnimate runAction：...但没有运行
