Updating text in pygame（1个答案）
1小时前关闭。
我正在尝试做一个大富翁游戏。但是一些显示问题出现了。当某人买了房子或什么东西，它的钱会更新到一个新的值。并且钱的屏幕位移会改变。但是在我的代码中，以前显示的值不会被覆盖或消失，并且当前值和以前的值会同时显示在屏幕上。Render_mulit_line

import pygame

size = (1400, 924)
screen = pygame.display.set_mode(size)

class related_information_about_player():
    def __init__(self, player, x_pos, y_pos):
        self.name = player.name
        self.money = player.money
        self.player = player
        self.x_pos = x_pos
        self.y_pos = y_pos
        self.text_input = (f"name: {self.name}\nmoney: {self.player.money}")

    def update(self):
        self.text_input = (f"name: {self.name}\nmoney: {self.player.money")

def render_multi_line(text, x, y, fsize):
    global screen
    lines = text.split("\n")
    for i, l in enumerate(lines):
        screen.blit(main_font.render(l, True, white), (x, y + size*i))

#main function and I have deleted other irrelated code
        information1.update()
        information2.update()
        information3.update()
        information4.update()
        render_multi_line(information1.text_input,
                          information1.x_pos, information1.y_pos, 22)
        render_multi_line(information2.text_input,
                          information2.x_pos, information2.y_pos, 22)
        render_multi_line(information3.text_input,
                          information3.x_pos, information3.y_pos, 22)
        render_multi_line(information4.text_input,
                          information4.x_pos, information4.y_pos, 22)

我希望看到更新后以前的值会消失
