10. 拼图游戏继续升级——多关卡拼图

• 初始化列表Photos用来储存拼图文件名，Photo_ID用来统计当下是第几张拼图，Squares储存当下拼图的24张小拼图的文件名，Gird储存当下窗口上显示的24个小拼图及坐标。

Photos=["girl_","boy_","cat_"]
Photo_ID=0
Squares=[]
Gird=[]

• 建立change_Photo()函数通过Photo_ID来初始化新一轮的拼图

def change_Photo():
    global Photo_ID
    Squares.clear()
    Gird.clear()
    for i in range(1,25):# 初始化最新图片的文件名
        if i<10:
            s=Photos[Photo_ID]+'0'+str(i)
        else:
            s=Photos[Photo_ID]+str(i)
        Squares.append(Actor(s))
    # 略 Squares、Gird的初始化

• 设定图片切换方法：上一张拼图胜利后按下空格键切换下一张拼图，再次将Is_Win设定为False
• 修改游戏胜利条件：Photo_ID等于Photos的长度且Is_Win为True时才能迎来最终的胜利

def on_key_down(key):
    global Photo_ID,Is_Win,Win_music
    if key == keys.SPACE:
        Photo_ID += 1
        if Photo_ID < len(Photos):
            Is_Win = False
            Win_music = 0
            change_Photo()

• 修改时间的更新条件

def update():
    global newTime,startTime,Photo_ID
    if (not Is_Win) or (Photo_ID!=len(Photos)):
        endTime = datetime.datetime.now()
        newTime=(endTime-startTime).seconds

• 再窗口上增加当下是第几张拼图的提示

def draw():
    # 略
    screen.draw.text("第" + str(Photo_ID+1)+"张图", (WIDTH-100, 10),\
     fontsize=20, fontname='s', color="blue")

• 当最后一张拼图完成增加提示

def draw():
    # 略
    if Is_Win:
        # 略
        if Photo_ID == len(Photos) :
            screen.draw.text("已是最后一张图了！", (WIDTH / 2 - 170, HEIGHT / 2 + 50), \
            fontsize=50, fontname='s', color="blue")

执行效果如下图所示：

    txtFile.write(score)
txtFile.close()
