我想要一段linux下可运行的shell编程实现推箱子小游戏的代码

好的，推箱子游戏是一个非常经典的小游戏，下面是一个简单的shell脚本实现：

#!/bin/bash

# 初始化地图
map=(
"#########"
"#@  $   #"
"###$#$###"
"#    $  #"
"#  $  ###"
"#####$  #"
"#      $#"
"###  #@ #"
"#########"
)

# 找到玩家和箱子的位置
find_player_and_box() {
  player_x=0
  player_y=0
  box_x=0
  box_y=0
  for ((i=0;i<${#map[@]};i++))
  do
    for ((j=0;j<${#map[i]};j++))
    do
      if [ "${map[i]:j:1}" = "@" ]; then
        player_x=$j
        player_y=$i
      elif [ "${map[i]:j:1}" = "$" ]; then
        box_x=$j
        box_y=$i
      fi
    done
  done
}

# 移动玩家
move_player() {
  dx=$1
  dy=$2
  if [ "${map[player_y+dy]:player_x+dx:1}" = " " -o "${map[player_y+dy]:player_x+dx:1}" = "." ]; then
    map[player_y]=${map[player_y]:0:player_x}" "${map[player_y]:player_x+1}
    player_x=$((player_x+dx))
    player_y=$((player_y+dy))
    map[player_y]=${map[player_y]:0:player_x}"@"${map[player_y]:player_x+1}
  elif [ "${map[player_y+dy]:player_x+dx:1}" = "$" ]; then
    if [ "${map[player_y+dy*2]:player_x+dx*2:1}" = " " -o "${map[player_y+dy*2]:player_x+dx*2:1}" = "." ]; then
      map[player_y+dy]=${map[player_y+dy]:0:player_x+dx}" "${map[player_y+dy]:player_x+dx+1}
      map[player_y]=${map[player_y]:0:player_x}" "${map[player_y]:player_x+1}
      player_x=$((player_x+dx))
      player_y=$((player_y+dy))
      map[player_y]=${map[player_y]:0:player_x}"@"${map[player_y]:player_x+1}
      map[player_y+dy*2]=${map[player_y+dy*2]:0:player_x+dx}"$"${map[player_y+dy*2]:player_x+dx+1}
    fi
  fi
}

# 判断是否完成
is_win() {
  for ((i=0;i<${#map[@]};i++))
  do
    for ((j=0;j<${#map[i]};j++))
    do
      if [ "${map[i]:j:1}" = "$" ]; then
        return 1
      fi
    done
  done
  return 0
}

# 打印地图
print_map() {
  clear
  for ((i=0;i<${#map[@]};i++))
  do
    echo ${map[i]}
  done
}

# 游戏循环
while true
do
  find_player_and_box
  print_map
  read -s -n1 key
  case "$key" in
    "w") move_player 0 -1;;
    "s") move_player 0 1;;
    "a") move_player -1 0;;
    "d") move_player 1 0;;
    *) continue;;
  esac
  is_win
  if [ $? -eq 0 ]; then
    echo "You win!"
    break
  fi
done

使用方法：

1. 将以上代码保存为一个文件，例如`push_box.sh`
2. 在终端中进入到该文件所在目录并运行`./push_box.sh`
3. 使用`w`、`a`、`s`、`d`来控制玩家移动，将所有箱子推到目标位置即可胜利

注意：以上代码只是一个简单实现，仅供参考。
