python之Pygame 按钮 get.pressed()

我只是 pygame 的新手，这是我的代码，片段。我有主按钮功能，在 gameloop 中我成功创建了一个交互式按钮，但我不完全知道，我如何在 gameloop 中按下按钮(“开始播放”)并填充我的 gameDisplay，例如...白色.提前致谢 ..................................................... ..................................................... ..................................................... .....

请您参考如下方法:

我希望这个程序能有所帮助。

import pygame,sys 
from pygame.locals import * 
 
pygame.init() 
screen = pygame.display.set_mode((400,400)) 
white=(255,255,255) 
blue=(0,0,255) 
bright_red = (255,0,0) 
red = (200,0,0) 
black=(0,0,0) 
color=white 
 
def changecolor(newcolor): 
    global color 
    color=newcolor 
 
while True: 
    screen.fill(color) 
 
    for event in pygame.event.get(): 
        if event.type == QUIT: 
            pygame.quit() 
            sys.exit() 
        elif event.type == MOUSEBUTTONUP: 
            # Whenever somebody clicks on the screen the color 
            # will change from the initial color to the color 
            # value you send to the function. Using this you could 
            # make it specifically for your button. Like calling 
            # the change color function whenever the button is clicked. 
            changecolor(blue) 
 
    pygame.display.update()
