bmp拼图游戏shell代码

以下是一个简单的bmp拼图游戏的shell代码，你可以根据需要进行修改：

#!/bin/bash

# 设置游戏参数
ROWS=3
COLS=3
BLANK=$((ROWS*COLS))
IMAGE="image.bmp"
WIDTH=$(identify -format "%w" $IMAGE)
HEIGHT=$(identify -format "%h" $IMAGE)
WIDTH_OF_PIECE=$((WIDTH/COLS))
HEIGHT_OF_PIECE=$((HEIGHT/ROWS))

# 生成初始拼图
convert $IMAGE -crop ${WIDTH_OF_PIECE}x${HEIGHT_OF_PIECE} \
  +repage +adjoin tile-%d.bmp
mv tile-$BLANK.bmp blank.bmp
shuffle=( $(shuf -e $(seq 0 $((BLANK-1)))) )

for ((i=0; i<BLANK; i++)); do
  mv tile-${shuffle[$i]}.bmp tile-$i.bmp
done

# 显示拼图
display -size $((WIDTH+4))x$((HEIGHT+4)) xc:white \
  -gravity center -composite -geometry +2+2 \
  $(for ((i=0; i<BLANK; i++)); do echo "tile-$i.bmp"; done) \
  -geometry +2+2 blank.bmp &
  
# 等待用户拖动拼图
while true; do
  read -n 1 -s -r -p "Press arrow keys to move the tiles. Press q to quit."
  echo
  case "$REPLY" in
    q) break ;;
    A) # Up arrow
      if ((BLANK/COLS < ROWS-1)); then
        mv tile-$((BLANK+COLS)).bmp blank.bmp
        mv tile-$BLANK.bmp tile-$((BLANK+COLS)).bmp
        mv blank.bmp tile-$BLANK.bmp
        ((BLANK+=COLS))
      fi ;;
    B) # Down arrow
      if ((BLANK/COLS > 0)); then
        mv tile-$((BLANK-COLS)).bmp blank.bmp
        mv tile-$BLANK.bmp tile-$((BLANK-COLS)).bmp
        mv blank.bmp tile-$BLANK.bmp
        ((BLANK-=COLS))
      fi ;;
    C) # Right arrow
      if ((BLANK%COLS > 0)); then
        mv tile-$((BLANK-1)).bmp blank.bmp
        mv tile-$BLANK.bmp tile-$((BLANK-1)).bmp
        mv blank.bmp tile-$BLANK.bmp
        ((BLANK-=1))
      fi ;;
    D) # Left arrow
      if ((BLANK%COLS < COLS-1)); then
        mv tile-$((BLANK+1)).bmp blank.bmp
        mv tile-$BLANK.bmp tile-$((BLANK+1)).bmp
        mv blank.bmp tile-$BLANK.bmp
        ((BLANK+=1))
      fi ;;
  esac
done

# 清除中间文件
rm tile-*.bmp

注意：此代码需要安装ImageMagick和shuf。在Ubuntu上，你可以使用以下命令进行安装：

sudo apt-get install imagemagick coreutils
