在Cocos2D中，如何让动画2等待动画1完成，然后再执行Objective-C

Question

在我的程序中，当你在iOS SIM卡上点击屏幕时，就会使用CCMoveTo发牌。动画需要.4秒才能完成。再次轻拍屏幕，下一副牌就发完了。第二个动画也需要.4秒。我所要做的就是禁止我的程序在第一个动画完成之前分发第二套牌。尝试了sleep()，显然不能达到预期的效果。我也尝试了几种不同的方式使用Cocos2d的CCDelayTime，但是没有得到想要的结果。做这件事最简单和/或最节省内存的方法是什么？

编辑：@crackity_jones -这是我的HelloWorldLayer文件和我为CCSprite创建的允许移动的类别：

HelloWorldLayer.h

#import <GameKit/GameKit.h>
#import "CCSprite+MoveActions.h"
#import "cocos2d.h"

    // globals
CCSprite *card1;
...
CCSprite *card9;

@interface HelloWorldLayer : CCLayer {
    NSMutableArray *deck;
    ...
    int touchCount;
}

...

@end

HelloWorldLayer.m

...

-(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    touchCount++;
    [self nextRound];
}

// one method to handle all rounds dealt
-(void)nextRound {
    if (touchCount == 1) {
        [self removeAllCards];
        [deck shuffle];
        [self dealFirstRound];
    } else if (touchCount == 2) {
        [self dealSecondRound];
    } else if (touchCount == 3) {
        [self dealThirdRound];
    } else if (touchCount == 4) {
        [self dealFourthRound];
    touchCount = 0;
    }
}

-(NSMutableArray *)makeDeck {
    // create mutable array of 52 card sprites
}

-(void)dealFirstRound {
    ...
    // declare, define, add card objects to layer at start-point here
    …
    // the "moveToPositionX" methods contain the animation code
    [firstCard moveToPosition1];
    [secondCard …2];
    [third...3];
    [fourth...4];
    }

// Also methods for removing all rounds of cards
…
@end

CCSprite (MoveActions)

#import "CCSprite+MoveActions.h"
#define kCardTravelTime .1

@implementation CCSprite (MoveActions)

-(void)moveToPosition1 {
    CGSize size = [[CCDirector sharedDirector] winSize];
    [self runAction:[CCMoveTo actionWithDuration:kCardTravelTime
                                        position:CGPointMake(size.width/2 - card1.contentSize.width/4, card1.contentSize.height/2 + holeCard1.contentSize.height/5)]];
    CCDelayTime *waitTime = [CCDelayTime actionWithDuration:.4];
    [self runAction:waitTime];
}

-(void)moveToPosition2 {
    CGSize size = [[CCDirector sharedDirector] winSize];
    CCDelayTime *delay = [CCDelayTime actionWithDuration:.2];
    CCMoveTo *move = [CCMoveTo actionWithDuration:kCardTravelTime
                                        position:CGPointMake(size.width/2 + card1.contentSize.width/4, card1.contentSize.height/2 + holeCard1.contentSize.height/5)];
    [self runAction:[CCSequence actions:delay, move, nil]];
}
// rest of the methods 3-9 look like the above, essentially

@end

你可以试试这个！如果需要，可以使用在CCSequence操作中插入一些CCDelaytime操作。

-(void)dealFirstRound {
    id card1Move = [CCCallBlock actionWithBlock:^{
        [firstCard moveToPosition1];
    }];
    id card2Move = [CCCallBlock actionWithBlock:^{
        [secondCard moveToPosition2];
    }];
    id card3Move = [CCCallBlock actionWithBlock:^{
        [thirdCard moveToPosition3];
    }];
    id card4Move = [CCCallBlock actionWithBlock:^{
        [fourthCard moveToPosition4];
    }];
    [self runAction:[CCSequence actions:
                     card1Move,
                     card2Move,
                     card3Move,
                     card4Move,
                     nil];
}

Answer 2

像这样做一个CCSequence：

[<<CCNode>> runAction:[[CCSequence actions:[deal hand],[CCDelayTime actionWithDuration:.4],[deal 2nd hand].. ,nil]];

这将执行第一个操作，delay for .4 s，执行第二个action..and，以便on..you可以添加您想要的操作数量
