如何查找在cocos 2D中某个时间段内视图是否被点击2次以上 [英] How to find if a view is tapped more than 2 times within certain time period in cocos 2D

问题描述

我在cocos 2D中开发游戏。在我的游戏中，我需要点按我的视图一定次数。如果用户尝试点击视图超出限制，它应该显示一个警报。

I am developing a game in cocos 2D. In my game I need to tap my view a certain number of times. If the user attempts to tap the view beyond the limit, it should display an alert.

请有人帮我找到视图上的水龙头数。最重要的是点击数不是同时。在总游戏中，用户只能点击一定次数，之后他们不应该点击视图。

Please can someone help me to find number of taps on the view. Most important is number of taps is not simultaneously. In the Total game the user can tap only a certain number of times, after which they should not tap the view.

推荐答案

您可以使用NSTimeInterval。

You can do this with NSTimeInterval.

    //decalre this in interface file
    NSTimeInterval      mLastTapTime;

。

-(id)init
{
    if(self = [super init])
    {
         mLastTapTime = [NSDate timeIntervalSinceReferenceDate];
    }
    return self;
}

//触摸方法

    NSTimeInterval currentTime = [NSDate timeIntervalSinceReferenceDate];
    NSTimeInterval diff = currentTime - mLastTapTime;

    if(diff < 0.3 )
    {
         //do whatever you want if user press with 0.3second
    }
    mLastTapTime = [NSDate timeIntervalSinceReferenceDate];
