今天郭先生发现大家更喜欢看我发的three.js小作品，今天我就发一个3d版本推箱子的游戏，其实webGL有很多框架，three.js并不合适做游戏引擎，但是可以尝试一些小游戏。在线案例请点击点击要制作一个推箱子游戏，正常要有以下4个步骤
定义一些数组，要有开始箱子数组、结束箱子数组、地面数组还有墙面数组，有这四个数组就可以组成一个关卡。
根据数组初始化地面墙面箱子和目标地点标志物。
使用FirstPersonControls控制器，控制相机移动，根据地面箱子和墙面算出可移动区域。
根据相机正对箱子时，用鼠标点击箱子，控制箱子移动，并做成功性校验。

下面我们上代码分析代码1. 定义数组1. 定义数组这四个数组分别是墙的数组、地面的数组、箱子初始位置数组和目标数组。
wallArr = [[0, 0], [1, 0], [2, 0], [3, 0], [3, 1], [4, 1], [4, 2], [4, 3], [5, 3], [5, 4], [5, 5], [5, 6], [4, 6], [3, 6], [2, 6], [1, 6], [0, 6], [0, 5], [0, 4], [0, 3], [0, 2], [0, 1]]

if (boxGroup) {
scene.remove(boxGroup)
