我正在创建一个游戏,你必须遵循粒子(div)并点击它们来“吃掉”它们。我目前遇到的问题是我找不到克隆每个div的方法,并给它一个随机的X和Y坐标值来定位它。

这是我的代码:

var x = e.pageX;
var y = e.pageY;

function reposition(div, x, y, randomMode) {

      if(randomMode == 1) {
        x = Math.floor(Math.random() * 990);
        y = Math.floor(Math.random() * 560);
      }

      $(div).animate({"left": x + "px"}, "slow");
      $(div).animate({"top": y + "px"}, "slow");
    }

    // need to find some way to duplicate the divs and move them in random directions

    setInterval(function() {
            for(var i = 1; i < 4; i++) {

              reposition("#grabItem", 0, 0, 1);
            }
          }, 2000);

//select all grab items, and since there will be multiple particles
//use a class to mark them, not an ID. This line is to capture all
//particles existing in the markup, that are not dynamically added later
var $particles = $('.grabItem');
//set your container that has all the particles
var $container = $('body');

//every two seconds add a new particle at random location
setInterval(function() {
   for(var i = 1; i < 4; i++) {
      $particles.add(CreateParticle());
      MoveParticles();
   }
}, 2000);

//creates a new particle and adds to the canvas
function CreateParticle(){
   return $('<div/>').addClass('grabItem').appendTo($container);
}

//randomly moves all the particles around
function MoveParticles() {
   $particles.each(function() {
      var x = Math.floor(Math.random() * 990);
      var y = Math.floor(Math.random() * 560);

      $(div).animate({"left": x + "px"}, "slow");
      $(div).animate({"top": y + "px"}, "slow");
   });
}

这将每两秒在随机位置添加一个新粒子并移动所有现有粒子(包括新粒子)。如果您需要精确的克隆方法,请查看jQuery的.clone()方法。

jQuery中存在Clone方法,您正在寻找它吗?
