pgzrun 拼图游戏制作过程详解（8，9）

8. 添加音效和背景音乐

• 循环播放背景音乐

sounds.bg_music.play(-1)

• 当两个拼图进行互换时播放效果音

def swap_Square(i,j):  # 两个拼图的位置互换
    sounds.chick.play()
    # 略

• 建立标记变量Win_music用以标记胜利音乐是否被播放过

Win_music=0

• 当游戏胜利时播放一次胜利音乐，并将标记取消

    if is_win:
        if Win_music==0:
            sounds.win_music.play()
            Win_music=1
        Is_Win=True

9. 添加其他功能和优化

• 从txt文件中读取历史最好成绩，如果没有成绩记录则写入初始化成绩。

try:
    txtFile=open("rank.txt",'r')
    score=txtFile.readline()
except:
    txtFile=open("rank.txt",'w')
    score = "您是第一个玩家"
    txtFile.write(score)
txtFile.close()

• 导入日期时间模块

import datetime

• 记录游戏开始时间startTime，初始化历史最好成绩oldTime，newTime是本轮游戏的计时器

startTime=datetime.datetime.now()
oldTime=int(score) if score.isdigit() else 9999
newTime=0

•  在游戏进行时不断地更新计时器newTime

def update():
    global newTime,startTime
    if not Is_Win:
        endTime = datetime.datetime.now()
        newTime=(endTime-startTime).seconds
    # 略

• 在游戏胜利是判断是否更新最好成绩并写入文档

def on_mouse_down(pos,button): # 当鼠标被点击时
    # 略
    if is_win:
        # 略
        if newTime
            txtFile=open("rank.txt",'w')
            txtFile.write(str(newTime))
            txtFile.close()

• 将历史最好成绩级计时器显示在窗口上

def draw():
    # 略
    screen.draw.text("游戏最佳记录: "+str(oldTime), (20, 10), fontsize=20,\
    fontname='s', color="blue")
    screen.draw.text("游戏运行时间: " + str(newTime), (WIDTH/2, 10), \
    fontsize=20, fontname='s', color="blue")

执行效果如下图所示：

完整代码如下：

import random
import datetime
 
try:
    txtFile=open("rank.txt",'r')
    score=txtFile.readline()
except:
    txtFile=open("rank.txt",'w')
    score = "您是第一个玩家"
    txtFile.write(score)
txtFile.close()
 
startTime=datetime.datetime.now()
oldTime=int(score) if score.isdigit() else 9999
newTime=0
