Question

大家好我的代码有问题。我有6个精灵从底部移动到顶部。可以触摸3个精灵。当我触摸时，精灵计数器将增加+1并且该精灵将被移除。我面临的问题是，当我选择该精灵时，计数器会增加到1，但如果我在半秒内选择该精灵两次，则计数器增加到2。我可以在第一次触摸时看到精灵消失，但为什么一旦它消失，它仍然可以检测到精灵边界框（如果在半秒内点击）。

我该如何解决这个问题？我正在使用cocos2d

P.S如果我在半秒后选择精灵没问题。

//other code

CGPoint gridu2 =ccp(80,-45);
CGPoint gridu3 =ccp(80,-130);
CGPoint gridu4 =ccp(80,-215);
CGPoint gridu7 =ccp(240,-45);
CGPoint gridu8 =ccp(240,-130);
CGPoint gridu9 =ccp(240,-215);

//left grid up
id actionMoveUp2 = [CCMoveTo actionWithDuration:7 position:ccp(80,winSize.height + 215)];
id actionMoveUp3 = [CCMoveTo actionWithDuration:7 position:ccp(80,winSize.height + 130)];
id actionMoveUp4 = [CCMoveTo actionWithDuration:7 position:ccp(80,winSize.height + 45)];

//right grid down
id actionMoveDown7 = [CCMoveTo actionWithDuration:7 position:ccp(240,winSize.height +255)];
id actionMoveDown8 = [CCMoveTo actionWithDuration:7 position:ccp(240,winSize.height +170)];
id actionMoveDown9 = [CCMoveTo actionWithDuration:7 position:ccp(240,winSize.height +85)];

correctColor1.position=gridu2;
correctColor2.position=gridu3;
correctColor3.position=gridu9;
random4.position=gridu4;
random5.position=gridu7;
random6.position=gridu8;

[correctColor1 runAction:actionMoveUp2];

[random4 runAction:actionMoveUp4];
[random5 runAction:actionMoveDown7];
[random6 runAction:actionMoveDown8];

[self addChild:correctColor1 z:10 tag:1];
[self addChild:correctColor2 z:10 tag:2];
[self addChild:correctColor3 z:10 tag:3];
[self addChild:random4 z:1 tag:14];
[self addChild:random5 z:1 tag:15];
[self addChild:random6 z:1 tag:16];

-(void)addToScore:(int)number
{
score=score+number;
[scoreLabel setString:[NSString stringWithFormat:@"%d",score]];
}

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
CGSize winSize =[[CCDirector sharedDirector] winSize];
UITouch* myTouch = [touches anyObject];
CGPoint location = [myTouch locationInView: [myTouch view]];
location = [[CCDirector sharedDirector]convertToGL:location];

// to remove touched sprite
int totalNumberOfItems=3;
for (int y=1; y < totalNumberOfItems; y++){
    CCSprite *temp = (CCSprite*)[self getChildByTag:y];

    CGRect correctColor = [temp boundingBox];

    if (CGRectContainsPoint(correctColor, location)) {
        NSLog(@"touched");
        [self removeChild:temp cleanup:YES ];
        [self addToScore:1];
        return;
    }

}

Answer 1

我认为您需要实现ccTouchEnded功能，以便检测触摸已结束并避免重复触摸。

Answer 2

您可以尝试一些事情。尝试将[self removeChild:temp cleanup:YES]放入ccTouchesEnded:方法中。我不确定那会起作用。

你可以做的另一件事是禁用触摸半秒钟。致电[self setIsTouchEnabled:NO]，然后在ccTouchesEnded:

延迟后将其设置为是

希望这有帮助
