Pygame实现监听鼠标的示例分析

Pygame实现监听鼠标的示例分析，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

初始化参数

import pygame, sysfrom pygame.locals import *def print_text(font, x, y, text, color=(0, 0, 0)):    """打印字体函数"""    img_text = font.render(text, True, color)    screen.blit(img_text, (x, y))pygame.init()screen = pygame.display.set_mode((400, 400))pygame.display.set_caption("监听鼠标活动")while True:    for event in pygame.event.get():        if event.type == QUIT:            pygame.quit()            sys.exit()    screen.fill((255, 255, 255))    pygame.display.update()

鼠标移动

event.type 事件为MOUSEMOTION，则为鼠标移动，event.pos可以获取当前位置，event.rel鼠标的偏移。

   event.type == MOUSEMOTION:            event.pos            event.rel

我们将位置输出出来，定义鼠标的位置和鼠标的偏移量

mouse_x = mouse_y = 0move_x = move_y = 0        print_text(font1, 0, 0, "鼠标事件")    print_text(font1, 0, 20, "鼠标的位置：" + str(mouse_x) + "," + str(mouse_y))    print_text(font1, 0, 40, "鼠标的偏移：" + str(move_x) + "," + str(move_y))

鼠标点击位置

MOUSEBUTTONDOWN和MOUSEBUTTONUP记录鼠标的按下和放开动作

mouse_down = mouse_up = 0mouse_down_x = mouse_down_y = 0mouse_up_x = mouse_up_y = 0

输出鼠标位置及其对用的按钮

pygame.mouse.get_pressed() 可以监听鼠标的三个按键。

x, y = pygame.mouse.get_pos()    print_text(font1, 0, 180, "鼠标位置:" + str(x) + "," + str(y))    b1, b2, b3 = pygame.mouse.get_pressed()    print_text(font1, 0, 200, "按钮:" + str(b1) + "," + str(b2) + "," + str(b3))
