键盘事件控制小球速度

import pygame, sys

pygame.init()
size = width, height = 600, 400
speed = [1, 1]
BLACK = 0, 0, 0
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Pygame壁球")
ball = pygame.image.load("D:/PYG02-ball.gif") #载入图片
ballrect = ball.get_rect() #生成对应矩形
fps = 300
fclock = pygame.time.Clock() # 计算刷新的时间间隔

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                speed[0] = speed[0] if speed[0] == 0 else (abs(speed[0]) - 1) * int(speed[0] / abs(speed[0]))
            elif event.key == pygame.K_RIGHT:
                speed[0] = speed[0] + 1 if speed[0] > 0 else speed[0] - 1
            elif event.key == pygame.K_UP:
                speed[1] = speed[1] + 1 if speed[1] > 0 else speed[1] - 1
            elif event.key == pygame.K_DOWN:
                speed[1] = speed[1] if speed[1] == 0 else (abs(speed[1]) - 1) * int(speed[1] / abs(speed[1]))
    ballrect = ballrect.move(speed[0], speed[1]) # 模拟壁球移动
    if ballrect.left < 0 or ballrect.right > width:
        speed[0] = - speed[0]
    if ballrect.top < 0 or ballrect.bottom > height:
        speed[1] = - speed[1]

    screen.fill(BLACK)
    screen.blit(ball, ballrect) # 让小球附着在矩阵上，随着矩阵移动
    pygame.display.update()
    fclock.tick(fps)

全屏版带esc退出，使用pygame.display.Info 感知屏幕信息

import pygame, sys

pygame.init()
VInfo = pygame.display.Info() # 感知屏幕信息
size = width, height = VInfo.current_w, VInfo.current_h
#size = width, height = 600, 400
speed = [1, 1]
BLACK = 0, 0, 0
screen = pygame.display.set_mode(size, pygame.FULLSCREEN) #每种机制应当设置相对处理方法
pygame.display.set_caption("Pygame壁球")
ball = pygame.image.load("D:/PYG02-ball.gif") #载入图片
ballrect = ball.get_rect() #生成对应矩形
fps = 300
fclock = pygame.time.Clock() # 计算刷新的时间间隔

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                speed[0] = speed[0] if speed[0] == 0 else (abs(speed[0]) - 1) * int(speed[0] / abs(speed[0]))
            elif event.key == pygame.K_RIGHT:
                speed[0] = speed[0] + 1 if speed[0] > 0 else speed[0] - 1
            elif event.key == pygame.K_UP:
                speed[1] = speed[1] + 1 if speed[1] > 0 else speed[1] - 1
            elif event.key == pygame.K_DOWN:
                speed[1] = speed[1] if speed[1] == 0 else (abs(speed[1]) - 1) * int(speed[1] / abs(speed[1]))
            elif event.key == pygame.K_ESCAPE:
                sys.exit()
    ballrect = ballrect.move(speed[0], speed[1]) # 模拟壁球移动
    if ballrect.left < 0 or ballrect.right > width:
        speed[0] = - speed[0]
    if ballrect.top < 0 or ballrect.bottom > height:
        speed[1] = - speed[1]

    screen.fill(BLACK)
    screen.blit(ball, ballrect) # 让小球附着在矩阵上，随着矩阵移动
    pygame.display.update()
    fclock.tick(fps)

设置标题中的图标

 

窗口最小化时暂停游戏

两种刷新方式，flip全刷，update只刷新更新的部分
