基于pygame的游戏
pygame 简介
首先，让我们简要回顾一下Pygame的历史吧~
Pygame最初是由Pete Shinner编写的，该项目于2000年10月启动，六个月后，pygame版本1.0发布。pygame是一个利用SDL（Simple DirectMedia Layer）写就的游戏库。SDL 是一个用于控制多媒体的跨平台C库，与DirectX相当，它已被用于数百种商业和开源游戏。Pete Shinner对Python和SDL两个项目的简洁与优雅印象深刻，他决定将Python和SDL结合起来，组建一个真正利用Python的项目，目标是让做简单的事情变得容易，让困难的事情变简单。
如何安装pygame
非常的easy！
直接打开运行cmd 输入pip install pygame 就可啦
好了 下面我们做一些pygame的基础操作
pygame基础
一、pygame窗口
1.导入pygame模块
2.设置窗口大小和窗口名称
3.参考代码
import pygame
from pygame.locals import *
import sys
def hello_world():
pygame.init()
pygame.display.set_mode((640,480))
pygame.display.set_caption("hello world")
while True:
for event in pygame.event.get():
if event.type==QUIT:
pygame.quit()
sys.exit()
pygame.display.update()
if __name__=="__main__":
hello_world()4.运行截图
二、实现坦克的自由移动
1.制作一个自由移动的坦克
2.通过方向键来控制坦克的移动
3.参考代码
import os,sys,pygame
from pygame.locals import *
def control_tank(event):
speed=[x,y]=[0,0]
speed_offset=1
if event.type==pygame.KEYDOWN:
if event.key==pygame.K_LEFT:
speed[0]-=speed_offset
if event.key==pygame.K_RIGHT:
speed[0]=speed_offset
if event.key==pygame.K_UP:
speed[1]-=speed_offset
if event.key==pygame.K_DOWN:
speed[1]=speed_offset
if event.type==pygame.KEYUP:
if event.type in[pygame.K_UP,pygame.K_DOWN,pygame.K_RIGHT,pygame.K_LEFT]:
speed=[0,0]
return speed
def play_tank():
pygame.init()
window_size=Rect(0,0,640,480)
speed=[1,1]
color_white=(255,255,255)
screen=pygame.display.set_mode(window_size.size)
pygame.display.set_caption("坦克大战")
tank_image=pygame.image.load('tankU.bmp')
back_image=pygame.image.load('back_image.jpg')
tank_rect=tank_image.get_rect()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
cur_speed=control_tank(event)
tank_rect=tank_rect.move(cur_speed).clamp(window_size)
screen.blit(back_image,(0,0))
screen.blit(tank_image,tank_rect)
pygame.display.update()
if __name__ == "__main__":
play_tank()4.运行截图
三、精灵类测试
“动画精灵”这个词是从老式计算机和游戏机流传下来的。这些老式游戏机不能很快地绘制和擦除图形来保证游戏正常工作。这些游戏机有一些特殊的硬件，专门用来处理需要快速移动的游戏对象。这些对象就称为“动画精灵”。它们有一些特殊的限制，不过可以非常快地绘制和更新……如今，一般来讲，计算机的速度已经足够快了，不需要专门的硬件也可以很好地处理类似动画精灵的对象。不过‘动画精灵’这个词仍用来便是二维游戏中的所有动画对象。 pygame.sprite.Sprite是pygame里面用来实现精灵的一个类，使用时并不需要对他实例化，只需要继承它，然后按需写出自己的类，因此非常简单实用。所有精灵再建立时都是从pygame.sprite.Sprite中继承的，建立精灵要设计自己的精灵类
案例一）：精灵坦克：
1. 参考代码
import pygame,sys
pygame.init()
class Tank(pygame.sprite.Sprite):
def __init__(self,filename,initial_position):
pygame.sprite.Sprite.__init__(self)
self.image=pygame.image.load(filename)
self.rect=self.image.get_rect()
self.rect.bottomright=initial_position
screen=pygame.display.set_mode([640,480])
screen.fill([255,255,255])
fi='tankU.bmp'
b=Tank(fi,[150,100])
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
screen.blit(b.image,b.rect)
pygame.display.update()2. 运行截图
