import pygame,sys
sys是Python标准库
sys.exit()用于结束游戏并退出
pygame.init()初始化创建
screen = pygame.display.set_mode((600,400))窗口设置
pygame.displa.set_caption(“Python游戏之旅”)标题
图像.get_rect()返回一个覆盖图像的矩形Rect对象
width,height
ball = pygame.image.load()载入图像,支持jpg,png
ballrect.move(x,y)x,y方向移动
screen.fill(R,G,B)窗口背景填充颜色
screen.blit(src,dest)将scr绘制到dest位置上,使得框和球一起动哦
屏幕绘制的函数:
屏幕尺寸和模式:
pygame.display.set_mode()设置相关屏幕模式
pygame.display.Info()生成屏幕相关信息
窗口标题和图标:
pygame.display.set_caption() 设置标题信息
pygame.display.set_icon()设置图标信息
pygame.display.get_caption()获得图标
窗口感知和刷新:
pygame.display.get_active()
pygame.display.flip()全部窗口刷新
pygame.display.update()仅刷新变化的区域
pygame.display.set_mode(r=(0,0),flags=0)
r分辨率(width,height)
flags:
pygame.RESIZABLE 窗口大小可调
pygame.NOFRAME 窗口没有边界显示
pygame.FULLSCREEN 窗口全屏显示
pygame.display.Info()
显示当前屏幕信息,在set_mode前使用
current_w:当前显示模式或窗口的像素宽度
current_h:当前显示模式或窗口的像素高度
pygame.display.set_caption(title,icontitle=None)
title设置窗口的标题内容
icontitle设置图标化的小标题
pygame.display.get_caption()
获得信息为一个元组(title, icontitle)
pygame.display.set_icon(surface)
设置窗口的图标效果
pygame.display.get_active()
窗口在系统中显示返回True,最小化时返回False
键盘事件:
键盘按下:pygame.event.KEYDOWN
返回值:
event.unicode 案件的unicode码,不推荐
event.key 按键常量名称
event.mod 按键修饰符的组合
键盘释放:pygame.event.KEYUP
返回值:
event.key 按键常量名称
event.mod 按键修饰符的组合 |符号
鼠标事件:
pygame.event.MOUSEMOTION鼠标移动事件
event.pos 鼠标当前坐标值(x,y)
event.rel 鼠标相对运动距离(x,y),相对于上次事件
event.buttons 鼠标按钮状态(a,b,c)，对应鼠标三个键,按下为1
pygame.event.MOUSEBUTTONUP鼠标释放事件
event.pos 鼠标当前坐标值
event.button 鼠标按下键编号n,取值0/1/2,分别对应三个键
pygame.event.MOUSEBUTTONDOWN鼠标释放事件
event.pos 鼠标当前坐标值
event.button 鼠标按下键编号n,左键1,右键3
事件处理函数:
处理函数:
pygame.event.get()获得事件列表
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
pygame.event.poll()从事件队列中获得一个事件:
while True:
event = pygame.evwnt.poll()
时间获取将从事件队列中删除,如果队列为空则返回event.NOEVENT
pygame.event.clear()从事件队列中删除事件,默认删除所有事件
操作事件队列:
pygame.event.set_blocked(type or typelist)
控制哪些事件不允许被保存在事件队列中
pygame.event.set_allowed(type or typelist)
控制哪些事件允许被保存在事件队列中
pygame.event.get_blocked(type)
测试某个事件类型是否被事件队列所禁止,返回True,False
事件操作:
pygame.event.post(Event)
产生一个事件,并将其放入事件队列
一般用于防止用户自定义事件(pygame.USEREVENT)
也可以用于放置系统定义事件(键鼠)
pygame.event.Event(type,dict)
创建一个给定类型的事件
事件的属性和值采用字典类型复制属性名采用字符串形式
色彩表示:
pygame.Color.r
pygame.Color.g
pygame.Color.b
pygame.Color.a alpha值
pygame.Color.normalize 将RGBA各通道值归一到0-1之间
