pygame入门实例——弹弹弹，小游戏！

解释看注释，加入自己的动画图片，替换timg.jpg

import pygame
import sys
from pygame.locals import *


#初始化pygame
pygame.init()

size = width, height = 600,400
speed = [-2,1]

#背景设置，全白
bg = (255,255,255)

#创建指定大小的窗口 Surface对象
screen = pygame.display.set_mode(size)
#设置窗口标题
pygame.display.set_caption("弹弹弹，小游戏！")

#加载图片
gamemaster = pygame.image.load("timg.jpg")
#获得图像的位置矩形
position = gamemaster.get_rect()

l_head = gamemaster
r_head = pygame.transform.flip(gamemaster,True,False)

#事件，终止事件
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()
            
        if event.type == KEYDOWN:
            
            if event.key == K_LEFT:
                gamemaster = l_head
                speed = [-2,1]
                    
            if event.key == K_RIGHT:
                gamemaster = r_head
                speed = [2,-1]
                     
            if event.key == K_UP:
                 speed = [1,-2]
                     
            if event.key == K_DOWN:
                 speed = [-1,2]
                      

        elif event.type == KEYUP:
                #speed =[-2,1]
            pass
        
    
    #移动图像
    position = position.move(speed)

    if position.left <0 or position.right > width:
        #图像翻转 gamemaster,True,False 左右翻转 上下不翻转
        gamemaster = pygame.transform.flip(gamemaster,True,False)
        #反方向移动
        speed[0] = -speed[0]

    if position.top <0 or position.bottom >height:
        #反方向移动
        speed[1] = -speed[1]


    #填充背景
    screen.fill(bg)
    #更新图像
    screen.blit(gamemaster,position)
    #更新界面
    pygame.display.flip()
    #延时10ms
    pygame.time.delay(10)

2.pygame入门实例——基本图形绘制，画个圆

同心圆跟着鼠标移动

import pygame
import sys
from pygame.locals import*

pygame.init()


WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
RED = (255,0,0)
BLUE =(0,0,255)

size = width,height = 640,480
screen = pygame.display.set_mode(size)
pygame.display.set_caption("基本图形绘制Demo")


position = size[0]//2,size[1]//2
moving = False

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            #pygame.quit()
            exit()

        #鼠标移动
        if event.type == MOUSEBUTTONDOWN:
            if event.button == 1:
                moving = True

        if event.type == MOUSEBUTTONUP:
            if event.button == 1:
                moving = False

    #得到鼠标位置，圆形移动
    if moving:
        position = pygame.mouse.get_pos()

    screen.fill(WHITE)

    #画圆形,position为圆心 
    pygame.draw.circle(screen, RED, position, 25, 1)
    pygame.draw.circle(screen, GREEN, position, 75,1)
    pygame.draw.circle(screen, BLUE, position, 125, 1)

    #更新图片
    pygame.display.flip()


    #设置帧率
    clock.tick(120)
