Question

所以我正在建立一个游戏，并且有一个js脚本，只为每个级别加载背景图像问题，我希望背景处于某个位置。如何在脚本中实现这一目标？

我的代码如下：

var levels = {
    level1: {
                level: [[["0","1","0","1"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"]],[["0","0","1","1"],["0","1","1","0"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"]],[["0","0","0","0"],["0","0","1","1"],["1","1","0","0"],["0","0","0","0"],["0","0","0","0"],["0","0","0","0"]],[["0","0","0","0"],["0","0","0","0"],["0","0","1","1"],["1","0","1","0"],["1","0","1","0"],["1","1","0","0"]]],
                backgroundURL : "http://google.co.uk/level1.jpg" 
            },

只需使用css属性background-position，如another stackoverflow post。

中所述

如果你使用jQuery，你可以做

$('#canvas').css('background-position', '10px 10px');

，其中

<div id="canvas">

是相关的HTML元素。

设置背景位置Javascript
