Python中pygame的mouse鼠标事件用法实例

本文实例讲述了Python中pygame的mouse鼠标事件用法。分享给大家供大家参考，具体如下：

pygame.mouse提供了一些方法获取鼠标设备当前的状态

    '''
    pygame.mouse.get_pressed - get the state of the mouse buttons  get the state of the mouse buttons
    pygame.mouse.get_pos - get the mouse cursor position  get the mouse cursor position
    pygame.mouse.get_rel - get the amount of mouse movement  get the amount of mouse movement
    pygame.mouse.set_pos - set the mouse cursor position  set the mouse cursor position
    pygame.mouse.set_visible - hide or show the mouse cursor  hide or show the mouse cursor
    pygame.mouse.get_focused - check if the display is receiving mouse input  check if the display is receiving mouse input
    pygame.mouse.set_cursor - set the image for the system mouse cursor  set the image for the system mouse cursor
    pygame.mouse.get_cursor - get the image for the system mouse cursor  get the image for the system mouse cursor
    '''

在下面的demo中，主要用到了:

pygame.mouse.get_pressed()

pygame.mouse.get_pos()

展示的效果：

游戏效果：

当鼠标经过窗口的时候，窗口背景颜色会随着鼠标的移动而发生改变，当鼠标点击窗口

会在控制台打印出是鼠标的那个键被点击了：左，右，滚轮

    #pygame mouse
    import os, pygame
    from pygame.locals import *
    from sys import exit
    from random import *
    __author__ = {'name' : 'Hongten',
           'mail' : 'hongtenzone@foxmail.com',
           'Version' : '1.0'}
    if not pygame.font:print('Warning, Can not found font!')
    pygame.init()
    screen = pygame.display.set_mode((255, 255), 0, 32)
    screen.fill((255,255,255))
    font = pygame.font.Font('data\\font\\TORK____.ttf', 20)
    text = font.render('Cliked Me please!!!', True, (34, 252, 43))
    mouse_x, mouse_y = 0, 0
    while 1:
      for event in pygame.event.get():
        if event.type == QUIT:
          exit()
        elif event.type == MOUSEBUTTONDOWN:
          pressed_array = pygame.mouse.get_pressed()
          for index in range(len(pressed_array)):
            if pressed_array[index]:
              if index == 0:
                print('Pressed LEFT Button!')
              elif index == 1:
                print('The mouse wheel Pressed!')
              elif index == 2:
                print('Pressed RIGHT Button!')
        elif event.type == MOUSEMOTION:
          #return the X and Y position of the mouse cursor
          pos = pygame.mouse.get_pos()
          mouse_x = pos[0]
          mouse_y = pos[1]
      screen.fill((mouse_x, mouse_y, 0))    
      screen.blit(text, (40, 100))
      pygame.display.update()
