"游戏"重启时,计时器不会重置

Question

功能:

用户在游戏页面中玩基于时间的游戏.将有倒数计时器来跟踪游戏持续时间,因此,当计数器= 0时,它将进行检查并评估用户是否满足游戏条件.

游戏条件如下:

1.)如果计数器等于0且速度超过20ms,它将前进到下一页

其他

2.)它将导航到"Gameover"页面,用户必须确认gameover页面,然后再返回到游戏起始页面

当用户在游戏中失败并重新开始游戏时,计数器将被重置,以便将其视为一个全新的游戏.

我做了什么:

我已经完成了,计数器也记录了速度,它正在游戏页面上显示.其次,我还设置条件语句来检查条件(counter == 0 && speed> 20),这假设分别将用户导航到正确的页面.

问题: 用户可以在游戏结束后导航到正确的页面,因此已完成的条件检查是正确的.但是,对于游戏失败并且必须重新启动游戏的用户,计时器不会重置为初始值; 例如,计数器= 10.意思是,当上一次游戏的计数器= 0时,它仍然设置在counter = 0,我明白这是因为我把它设置为clearInterval(rollingInterval),因此它清除了计数器并且速度没有重置为0.00ms但是之前的速度仍在显示.

但是,我想问一下,当用户重启游戏时,我怎么能将计数器重置为counter = 10以及重置速度= 0.00ms？

我附上了您的细读代码:

function Page2() {
  $("#page1").hide();
  $("#page2").show();
}

//script for div id =page2
function MainGame(){
               var numOfSpin = 0,
                distanceCovered = 0,
                counter = 0,
                timer = 10;
               var rollingInterval;
                
                $("#scrollerDiv").scroll(function() {
                    var height = $("#scrollerDiv").scrollTop();
                    for ( var i = 0; i < 250; i ++ ) {
                        if ( height > i * 10 ) {
                            if ( i >= 0 && i < 10 ) {
                                $("#roller").attr("src", "Image/rolling_pin/Rolling Pin Spin00"+i+".png");
                            }
                            if ( i >= 10 && i < 100 ) {
                                $("#roller").attr("src", "Image/rolling_pin/Rolling Pin Spin0"+i+".png");
                            }
                            if ( i >= 100 && i < 1000 ) {
                                $("#roller").attr("src", "Image/rolling_pin/Rolling Pin Spin"+i+".png");
                               
                                $("#scrollerDiv").scrollTop(0);
                                numOfSpin++;
                                distanceCovered += 0.59;
                                console.log(distanceCovered);
                                console.log(numOfSpin);
                            }
                        }
                    }
			
                })
        
               rollingInterval = setInterval(function() {
                    counter = counter + 1;
                    timer = timer - 1;
                    speed = distanceCovered / counter;
                    speed2dec = speed.toFixed(2);
                    //document.getElementById("speedSpan").innerHTML = speed2dec + "<br/>"+"ms";
                    $('#speedSpan').html(speed2dec+'<br>ms');
                    //document.getElementById("timeSpan").innerHTML = timer + "s"
                    $('#timeSpan').html(timer+'s');
                   
                    //Ernest_Lee 13/11/15: Set Conditional Checks; user satisfy game condition, advance to next page, else navigate to the "GameOver" Page.
                    if ( counter == 10 && speed >20) {
                        console.log("Count");
                        clearInterval(rollingInterval);
                        $("#page2").hide();
                        $("#page3").show();
                    }else if( counter == 10 && speed <20) {
                        clearInterval(rollingInterval);
                        $("#page2").hide();

                    }
                }, 1000)

Answer 1

很简单，我刷新了整个页面。因此，这就是我重置计数器和所有其他设置的方法：

location.reload();

以下行位于： 内function RevertPage(){..}。因此，代码将如下所示：

function RevertPage() { 
//navigate user to game page immediately.
//Refresh entire LaunchPage
location.reload();
console.log("GameFail Navigate");
}
