Uefi Application小游戏开发之推箱子
小游戏之推箱子
推箱子（Pushbox）是一个经典的益智游戏，其C语言实现需要设计一个游戏循环，处理用户输入，并更新游戏状态
- 创建地图 game_map[20][20]
- While{} 循环检测按键输入，gST->ConIn->ReadKeyStroke(gST->ConIn,&key)读取按键信息
- 初始人物的位置为S 位置为 game_map [1][2],X=1 ，Y=2
- 处理上下左右按键，处理按键上下左右，更新地图信息，上X-1，如果 game_map[x-1][y]==' '，那么就替换 game_map[x-1][y]和game_map[x][y]，如果下一格对应到(game_map[x-1][y]=='O'）那就要考虑game_map[x-2][y]是什么 如果为 ' '那就是S 和 O 一起走一步,如果无法走就不执行，其他的方向操作原理相同，然后更新打印
