触摸问题建议

Question

大家好，我的代码有问题。我有6个从底部到顶部移动的精灵。3个精灵可以被触摸。当我触碰那个精灵计数器时，它将增加+1，并且那个精灵将被移除。我面临的问题是，当我选择那个精灵时，计数器会增加到1，但如果我在半秒内选择那个精灵两次，计数器就会增加到2。我可以看到在第一次触碰时精灵消失了，但为什么一旦它消失，它仍然可以检测到精灵的边界框(如果在半秒内点击)。

我该如何解决这个问题?我使用cocos2d

p。如果我在半秒后选择精灵，没有问题。

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)];

}
-(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

我认为你需要实现一个ccTouchEnded函数，这样你就可以检测触摸已经结束并避免重复触摸

Answer 2

您可以尝试以下几种方法。尝试将[self removeChild:temp cleanup:YES]放入ccTouchesEnded:方法中。我不确定那是否可行。

你可以做的另一件事是禁用触摸半秒。呼叫[self setIsTouchEnabled:NO]，等待ccTouchesEnded:延时后设置为yes

希望能有所帮助
