Question

我正在尝试为我的游戏添加一个分数，每当多维数据集通过差距时，它会添加一个得分。我尝试了一些不同的方法，但没有一个适合我。这是我的脚本，我在那里有三个html，css和javascript，抱歉，如果它有点乱。谢谢。 PS。我必须在这个问题上加入更多信息才能发布

None

>>> response.xpath('//div//a[contains(@href, "product")]/@href').extract_first()
[u'/product_1', u'/product_1']

>>> response.xpath('//div//a[contains(@href, "product")]/@href').extract_first()
u'/product_1'

Answer 1

if (pieceY == height) {
     if (pieceX < length || pieceX > length + 20) {
        document.getElementById("lose").style.visibility = "visible";
     }
  //Here add
  myScore = myScore +1;
  document.getElementById("score").innerHTML = myScore;
}

停止动画（当你想要停止时将gameIsOver设置为true）：

 var stop,gameIsOver;
 function init() {

    ctx = canvas.getContext('2d');
    stop = setInterval(draw,10);
    document.getElementById('lose').style.visibility = "hidden";
 }
function draw(){
  if(gameIsOver){
    clearInterval(stop);
  }
}

Answer 2

停止绘制功能，记录间隔id：

var interval_id;

function init() {

  ctx = canvas.getContext('2d');
  document.getElementById('lose').style.visibility = "hidden";
  interval_id = setInterval(draw,10); // to record the interval id
}

并在丢失时通过该ID清除间隔：

if (pieceY == height) {
  if (pieceX < length || pieceX > length + 20) {

    // to stop the draw interval
    clearInterval(interval_id);

    document.getElementById("lose").style.visibility = "visible";
  }

  myScore = myScore + 1;

  // to update the score to the view
  document.getElementById("score").innerHTML = myScore;
}

重启游戏：

function restart() {

  // reset all variables that changed to it's initial value
  pieceX = 200;
  pieceY = 400;
  height = 0;
  myScore = 0;

  // reset view
  document.getElementById("score").innerHTML = myScore;
  document.getElementById('lose').style.visibility = "hidden";

  // start the interval loop(it will return a different id)
  interval_id = setInterval(draw, 10); // to record the interval id
}

添加到变量
