pygame介绍
Pygame被设计用来写游戏的python模块集合，基于SDL库开发。使用python可以导入pygame来开发具有全部特性的游戏和多媒体软件，Pygame是极度轻便的并且可以运行在几乎所有的平台和操作系统上。
1. 导入依赖 & 通用配置
import random
import sys
import time
from urllib.request import urlretrieve
import os
import pygame
SCREEN_WIDTH, SCREEN_HEIGHT = 1200, 700 # 画面大小
MY_BIRTH_LEFT, MY_BIRTH_TOP = SCREEN_WIDTH / 2, SCREEN_HEIGHT - 60
DIRECTION = [U, D, L, R] = [ U , D , L , R ] # 控制键
Tank_IMAGE_POSITION = r D:/tank_img
URL = https://gitee.com/tyoui/logo/raw/master/img/2. 通用加载函数
# 加载图片
def load_img(name_img):
save = Tank_IMAGE_POSITION + os.sep + name_img + .gif
if not os.path.exists(save):
urlretrieve(URL + name_img + .gif , save)
return pygame.image.load(save)
# 加载背景音乐
def load_music(name_music):
save = Tank_IMAGE_POSITION + os.sep + name_music + .wav
if not os.path.exists(save):
urlretrieve(URL + name_music + .wav , save)
pygame.mixer.music.load(save)
pygame.mixer.music.play()3. 通用基础类
* pygame.sprite模块，官方文档上说这个模块是轻量级的，在游戏开发中也未必要使用。
* sprite翻译为精灵，在游戏动画一般是指一个独立运动的画面元素，在pygame中，
就可以是一个带有图像（Surface）和大小位置（Rect）的对象。
* pygame.sprite.Sprite是pygame精灵的基类，一般来说，需要写一个自己的精灵类继承一下它然后加入自己的代码。
