Question

我正在制作一个＆＃34; Match-3＆＃34;使用＆＃34;扑克牌打造游戏＆＃34;捻。

背景信息，不相关 - ＆gt;这场比赛是Scat（或31）游戏的一个转折点。目标是制作3张相同套装的牌，其中Ace值为11（因此31是最高分）。

我已经让游戏运行得很好，在卡片被移除并且新卡片落入到位后发生了连击和链条。

我的下一个目标是让玩家知道可能的＆＃34;交换＆＃34;从最后一次交换后的几秒钟，然后每隔2秒，直到交换完成。我决定制作卡片＆＃34;摇晃＆＃34;半秒钟，它看起来很棒。

我的问题是，一旦交换发生，并且删除/删除/替换动画开始，＆＃34;未使用＆＃34;交换中的卡片一直在摇晃，当大型组合发生时这一点特别明显，这一张小卡片每隔两秒就会持续摇晃！

我意识到有一千种方法可以解决这个问题，但我真的没有遇到过这么好的方法！以下是我的相关功能：



- (void)updateWithTimeSinceLastUpdate:(CFTimeInterval)timeSinceLast
{
    self.lastSwapTimeInterval += timeSinceLast;

    if (self.lastSwapTimeInterval > 2)
    {
        self.lastSwapTimeInterval = 0;
        [self showPossibleSwap];
    }
}

-(void)update:(NSTimeInterval)currentTime
{
    CFTimeInterval timeSinceLast = currentTime - self.lastUpdateTimeInterval;
    self.lastUpdateTimeInterval = currentTime;

    if (timeSinceLast > 1)
    {
        timeSinceLast = 1.0 / 60.0;
        self.lastUpdateTimeInterval = currentTime;
    }

    [self updateWithTimeSinceLastUpdate:timeSinceLast];
}

-(void)animatePossibleSwap:(BGSSwap *)swap
{
    BGSCard *first = swap.cardA;
    BGSCard *second = swap.cardB;

    const NSTimeInterval timeDiff = 0.05;

    SKAction *rot15r = [SKAction rotateByAngle:-[self degreesToRadian:15] duration:0.05];
    SKAction *rot30 = [SKAction rotateByAngle:[self degreesToRadian:30] duration:0.1];
    SKAction *rot30r = [SKAction rotateByAngle:-[self degreesToRadian:30] duration:0.1];

    [first.sprite runAction:[SKAction sequence:@[rot15r,rot30,rot30r,rot30,rot15r]]];
    [second.sprite runAction:[SKAction sequence:@[[SKAction waitForDuration:timeDiff],rot15r,rot30,rot30r,rot30,rot15r]]];
}

-(void)showPossibleSwap
{
    BGSSwap *swap = [self.level.possibleSwaps anyObject];

    [self animatePossibleSwap:swap];

    NSLog(@"Show Possible Swap NOW: %f",_lastSwapTimeInterval);
}

- (void)updateWithTimeSinceLastUpdate:(CFTimeInterval)timeSinceLast { self.lastSwapTimeInterval += timeSinceLast; if (self.lastSwapTimeInterval > 2) { self.lastSwapTimeInterval = 0; [self showPossibleSwap]; } } -(void)update:(NSTimeInterval)currentTime { CFTimeInterval timeSinceLast = currentTime - self.lastUpdateTimeInterval; self.lastUpdateTimeInterval = currentTime; if (timeSinceLast > 1) { timeSinceLast = 1.0 / 60.0; self.lastUpdateTimeInterval = currentTime; } [self updateWithTimeSinceLastUpdate:timeSinceLast]; } -(void)animatePossibleSwap:(BGSSwap *)swap { BGSCard *first = swap.cardA; BGSCard *second = swap.cardB; const NSTimeInterval timeDiff = 0.05; SKAction *rot15r = [SKAction rotateByAngle:-[self degreesToRadian:15] duration:0.05]; SKAction *rot30 = [SKAction rotateByAngle:[self degreesToRadian:30] duration:0.1]; SKAction *rot30r = [SKAction rotateByAngle:-[self degreesToRadian:30] duration:0.1]; [first.sprite runAction:[SKAction sequence:@[rot15r,rot30,rot30r,rot30,rot15r]]]; [second.sprite runAction:[SKAction sequence:@[[SKAction waitForDuration:timeDiff],rot15r,rot30,rot30r,rot30,rot15r]]]; } -(void)showPossibleSwap { BGSSwap *swap = [self.level.possibleSwaps anyObject]; [self animatePossibleSwap:swap]; NSLog(@"Show Possible Swap NOW: %f",_lastSwapTimeInterval); }

在摇动SKActions上使用withKey :为每个动画命名。然后，当您确定动画不再适用时，可以使用removeActionforKey:。

停止按特定时间间隔设置的操作
