如何在点击按钮后在pygame中显示文本

import pygame
from pygame.locals import *

pygame.init()

screen = pygame.display.set_mode((width, height))

pygame.display.set_caption("显示文本示例")

font = pygame.font.Font(None, font_size)

text = font.render("要显示的文本", True, text_color)

button = pygame.Rect(x, y, width, height)

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEBUTTONDOWN:
            if button.collidepoint(event.pos):
                # 在按钮被点击后显示文本
                screen.blit(text, (text_x, text_y))

pygame.display.flip()

import pygame
from pygame.locals import *

pygame.init()

width = 800
height = 600
font_size = 32
text_color = (255, 255, 255)
text_x = 100
text_y = 100

screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("显示文本示例")

font = pygame.font.Font(None, font_size)
text = font.render("要显示的文本", True, text_color)

button = pygame.Rect(200, 200, 100, 50)

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEBUTTONDOWN:
            if button.collidepoint(event.pos):
                screen.blit(text, (text_x, text_y))

    pygame.display.flip()
