Question

大家好我正在尝试制作Javascript游戏。我有一些问题 - 为什么不是我的stone.png移动，我告诉它移动javascript。 - 有人能告诉我这是不是很好的OOP编程并帮助我？

HTML：

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>game</title>

   <script type="text/javascript" src="game.js"></script>
   <script type="text/javascript" src="js/easel.js"></script>
   <link rel="stylesheet" href="style.css">

</head>
<body onload="init();">


<canvas id=canvas width="960" height="580"></canvas>


</body>
</html>

使用Javascript：

var canvas;
var stage;
var score;
var bitmap;
var bmpList;
var txt;
var play;

function init() {
    canvas = document.getElementById("canvas");
    stage = new Stage(canvas);
    score = 0;

    var image = new Image();
    image.src = "imgs/stone.png";
    image.onload = maakTegenstander;
}



function maakTegenstander(stone){

    var image = event.target;
    var container = new Container();
    stage.addChild(container);


    var aantal = 8;
    bmpList=[];
    for(var i=0; i<aantal; i++){
        bitmap = new Bitmap(image);
        container.addChild(bitmap);
        bitmap.name="stone"+i;      
        resetTegenstander(bitmap);
        bitmap.regX = bitmap.image.width/2|0;
        bitmap.regY = bitmap.image.height/2|0;
        bmpList.push(bitmap);
    }

    txt = new Text ("Punten: 0", "24px Arial", "#FFF");
    txt.textBaseline="top";
    txt.x = 800;
    txt.y = 20;
    stage.addChild(txt);
    stage.update();
    play=true;

    Ticker.addListener(window);

}



function resetTegenstander(stone){

    stone.x = canvas.width - Math.random()*500;
    stone.y = canvas.width * Math.random()|0;
    stone.speed = (Math.random()*5)+2;


    }

function tijd(){
    if(play == true){
        var l=bmpList.length;

    }
    if (play == true){
        var l = bmpList.length;
        for(var i=0; i<l; i++){
            var bmp = bmpList[i];
            if (bmp.x > -200){
                bmp.x -= bmp.speed;
            }else{
                //gameOver();
                console.log("game over");
            }
        }
    }
    txt.text = "Score: "+score;
    stage.update();

OOP编程Javascript，移动对象
