根据pygame中的点击更改图片

在这里，我进行了简单介绍，以展示鼠标的工作原理。该行

if event.button ==1:

import pygame, sysfrom pygame.locals import *TIMER = 30SCREEN_X = 200SCREEN_Y = 200screen = pygame.display.set_mode((SCREEN_X, SCREEN_Y))clock = pygame.time.Clock() #tick-tockending = button1 = button2 = Falsecorner1 = (28,18)  #Top Left corner of button 1corner2 = (56,18)  #Top Left corner of button 2image_length = 100 #length of the buttonsimage_height = 100 #height of the buttonscounter = 0#Main Loop:while ending==False:    counter+=1    clock.tick(TIMER)    for event in pygame.event.get():        if event.type == KEYDOWN: if event.key == K_ESCAPE:     ending=True # Time to leave     print("Game Stopped Early by user")        elif event.type == MOUSEBUTTONDOWN: if event.button == 1:     mouse_x, mouse_y = event.pos     if (mouse_x >= corner1[0]) and (mouse_x <= corner1[0]+image_length) and (mouse_y >= corner1[1]) and (mouse_y <= corner1[1]+image_height):         print ("Button one is selected")         button1=True         button2=False     elif (mouse_x >= corner2[0]) and (mouse_x <= corner2[0]+image_length) and (mouse_y >= corner2[1]) and (mouse_y <= corner2[1]+image_height):         print ("Button two is selected")         button1=False         button2=True     else:         print ("That's not a button")         button1=False         button2=False    if counter == TIMER:  #prints the statements once a second        counter=0        if button1==True: print ("Button one is currently selected")        elif button2==True: print ("Button two is currently selected")        else: print ("No buttons currently selected")

在底部的打印语句中。如果button1或button2变量分别为，则只需将选择的图像用于按钮1或2

True
