Java版推箱子（搬箱子）游戏开发入门示例及源码

分类: 文章 • 2024-01-03 17:12:46

推（搬）箱子，又名Sokoban，仓库番等，是一款堪称古玩级的电脑游戏。

提起它，笔者相信没什么人会感觉到陌生，更没什么生物会连听都没听说过。它的发展历史之久远，甚至超越了俄罗斯方块（1988年电脑游戏化）。

这款游戏最初起源于日本，是个很难争辩的事实（我知道有人反对，但笔者确实找不到什么有力的反对证据）。他由日本人（哎……）今川宏行在1981年创立游戏规则，并于1982年经日本软件公司Thinking Rabbit正式发布。比较遗憾的是，早期的推箱子并没有PC版，笔者在网络上搜索到的老版游戏也大多为90年以前的Mac OS下程式。

但说起真正令推箱子风靡于PC机的，却该感谢我们的*同胞李果兆先生。是他在1994年开发的仓库世家，才真正令推箱子游戏在世界各地大受推崇；仔细说来，推箱子这款小游戏之所以能有今时今日的声望与地位，固然有今川宏行的开创之功，但若说到贡献最大，承前启后的，则非中国*的李果兆先生莫属。

推箱子游戏的规则非常简单，就是用尽量少的推动或移动把所有箱子都推到目标点上。箱子只能推动而不能拉动；一次只能推动一个箱子。然而，尽管它的规则是很简单的，但对于不同难度的关卡，所需要的脑力却是截然不同的，有些关卡可能会花费您几个小时、几天甚至几个月的时间，也正是这种简单性和复杂性的结合，最终令推箱子类游戏风靡全球！

本回笔者在Blog中提供的，就是一款Java版推箱子游戏的简单实现。

笔者设定[上、下、左、右]为方向控制 ，[S]键为后退到上一步操作，[ESC]为重新开始当前关卡，点击键盘上对应关卡的数字键可以直接选关，需要注意的是笔者以HP限制了角色的移动次数，HP归0则挑战失败。

目前版本仅提供有5关，有需要者可参考同类游戏自行扩充，游戏源码在jar内。
