pygame

基本流程

import pygame
#1. 初始化pygame
    pygame.init()

    #2. 创建游戏窗口
    #set_mode(宽度,高度)
    screen = pygame.display.set_mode((600,400))

    #3. 游戏循环
    while True:
        #检测事件
        for event in pygame.event.get():
            #检测关闭按钮是否被点击
            if event.type == pygame.QUIT:
                #退出游戏
                print('关闭按钮被点击!')
                exit()

    pygame.init()
    screen = pygame.display.set_mode((700,400))
    #设置窗口颜色
    screen.fill((38,54,64))
    #1. 创建字体对象
    '''
    创建系统字体
    SysFont(name, size, bold=False, italic=False)
    name:字体名
    size:字体大小
    bold:加粗
    italic:倾斜
    font = pygame.font.SysFont('times',50)
    '''

    '''
    创建自定义字体
    Font(字体文件路径,字体大小)
    '''
    font = pygame.font.Font('./font/aa.ttf',300)

    #2. 根据字体创建显示对象
    '''
    render(text, antialias, color, background=None)
    text: 要显示的文字内容
    antialias: 是否平滑
    color: 文字颜色 RGB 值的范围0~255

    绿色: (0,255,0)
    蓝色: (0,0,255)
    '''
    surface = font.render('流批!',True,(0,216,255))
    '''
    3. 将内容添加到窗口上
    blit(需要显示的对象, 显示位置)
    需要显示的对象: Surface类型的数据
    显示位置: 坐标(x,y)
    '''
    screen.blit(surface,(0,50))

    '''
    4. 将窗口上的内容展示出来(将画有文字的纸贴出来)
    '''
    pygame.display.flip()

        for event in pygame.event.get():
            if event.type == pygame.QUIT:

动画原理

通过不停的重置窗口画面实现动画效果

import pygame
if __name__ == '__main__':
    pygame.init()
    screen = pygame.display.set_mode((600,400))
    screen.fill((255,255,255))
    x=0
    y=0

    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                exit()
        x+=1
        y+=1
        screen.fill((255,255,255))
        pygame.draw.circle(screen,(255,0,0),(x,y),80)
        pygame.display.flip()
