01.pygame事件

import pygame

pygame.display.flip()
while True:
    # 每次循环检测有没有事件发生
    for event in pygame.event.get():
        # 不同类型的事件对应的type值不一样
        if event.type == pygame.QUIT:

        if event.type == pygame.KEYUP:

02.鼠标事件的应用

import pygame
from random import randint

    return True
return False

# 画一个按钮的函数
def draw_button(screen,bith_color,title_color):
pygame.draw.rect(screen, (0, 0, 0), (100, 100, 100, 60))
font = pygame.font.SysFont('Times', 30)
title = font.render('skrskr~', True, title_color)
screen.blit(title, (120, 120))

if __name__ == '__main__':
pygame.init()

03.鼠标事件的应用2

# 要求：鼠标按下移动的时候，拽着图片一起动，鼠标弹起就不动了
import pygame

def is_in_rect(point,rect):
x,y = point

    return True
return False

if __name__ == '__main__':
pygame.init()
screen = pygame.display.set_mode((600,400))
screen.fill((255,255,255))
pygame.display.set_caption('图片拖动')

image = pygame.image.load('./123.jpg')
image_x = 0
image_y = 0
screen.blit(image, (image_x, image_y))

is_move = False   #用来存储图片是否可以移动



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

        # 鼠标按下，让状态可以移动
        if event.type == pygame.MOUSEBUTTONDOWN:
            w,h = image.get_size()
            if is_in_rect(event.pos,(image_x,image_y,w,h)):
                is_move = True

        # 鼠标弹起，让状态变成不可以移动
        if event.type == pygame.MOUSEBUTTONUP:
            is_move = False

        # 鼠标移动对应的事件
        if is_move:
            if event.type == pygame.MOUSEMOTION:
                screen.fill((255,255,255))
                x,y = event.pos
                image_w,image_h = image.get_size()
                image_x = x - image_w/2

04.动画效果

动画原理：不断刷新界面上的内容（一帧一帧的画）

screen.blit(title, (100, 100))


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

pygame.display.flip()

    # for里面的代码只有事件发生后才执行
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()

    # 在下面去写每一帧现实的内容
    pygame.time.delay(60) #程序执行到这个位置，线程阻塞指定的时间  单位：毫秒（1000ms = 1s）
    screen.fill((255,255,255))   #将原来的内容清空
    static_page(screen)
    animation_title(screen)
