一、下载
pip install pygame
; 二、基础应用
2.1 生成窗口
代码如下（示例）：
import pygame
pygame.init()
screen = pygame.display.set_mode((800,600))
screen.fill((255,255,255))
pygame.display.flip()
gRunning = True
while gRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gRunning = False
pygame.quit()
这是一个渐变过程由黑变白（没有放GIF图）
2.2 加入图片
代码如下（示例）：
image = pygame.image.load(r'F:\python\python2021\python_gui\cdsc.jpg')
screen.blit(image,(0, 0))
2.2 加入声音
代码如下（示例）：
voice = pygame.mixer.music.load(r'F:\MP3音乐\千年之恋.mp3')
pygame.mixer.music.play()
2.3 改变颜色
代码如下（示例）：
from pygame.color import THECOLORS
screen.fill(THECOLORS['red'])
2.4 加入图形
代码如下（示例）：
pygame.draw.rect(screen,THECOLORS['blue'],[0,0,200,400],0)
pygame.draw.circle(screen,THECOLORS['green'],[400,300],100,10)
三、Pygame飞机
3.1 飞机跳跃
代码如下（示例）：
gRunning = True
while gRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gRunning = False
pygame.time.delay(1000)
pygame.bilt(img,(400,300))
pygame.draw.rect(screen,THECOLORS['white'],img.get_rect(),0)
pygame.display.flip()
3.2 飞机碰壁回弹
代码如下（示例）：
plane_x = 0
plane_y = 0
plane_speed_x = 5
plane_speed_y = 5
......
gRunning = True
while gRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gRunning = False
pygame.time.delay(20)
pygame.draw.rect(screen,THECOLORS['white'],[plane_x,plane_y,img.get_width(),img.get_height()],0)
plane_x = plane_x+plane_speed_x
plane_y = plane_y+plane_speed_y
if plane_x > 800-img.get_width() or plane_x < 0:
plane_speed_x = - plane_speed_x
if plane_y > 600-img.get_height() or plane_y < 0:
plane_speed_y = - plane_speed_y
screen.blit(img,(plane_x,plane_y))
pygame.display.flip()
3.3 模拟飞机
代码如下（示例）：
class Plane:
def __init__(self,img,position,speed,MaxWindow):
self.img = img
self.rect = img.get_rect()
self.rect.left,self.rect.top = position
self.speed = speed
self.MaxWindow = MaxWindow
def move(self):
self.rect = self.rect.move(self.speed)
if self.rect.left < 0 or self.rect.right >self.MaxWindow[0]:
self.speed[0] = -self.speed[0]
if self.rect.top< 0 or self.rect.bottom>self.MaxWindow[1]:
self.speed[1] = -self.speed[1]
pygame = init()
W_size = (800,600)
screen = pygame.display.set_mode(W_size)
screen.fill(THECOLORES['white'])
planeImg = pygame.image.load('plane.png')
planes = []
for i in range(5)
position = [random.randint(0,W_size[0]-planeImg.get_width(),random.randint(0,W_size[1]-planeImg.get_hright())]
speed = [random.randint(-5,5),random.randint(-5,5)]
planes.append(Plane(planeImg,position,speed,W_size))
pygame.display.flip()
gRunning = True
while gRunning:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gRunning = False
pygame.time.delay(20)
screen.fill(THECOLORES['white'])
for plane in planes:
plane.move()
screen.blit(plane.img,plane.rect)
pygame.display.flip()
pygame.quit()
