Python 输入文本上的Pygame退格键未清除。而是重叠/

为了更清楚地了解问题，请参见图片：

如图所示，我输入了一些文本。我决定退格，但我输入的新文本与前一个文本重叠。为什么会这样

pygame新手，且已被此问题困扰太久：(

请帮忙！我该怎么办

如果不作弊：
WIN=pygame.image.load（“Assets/winBox.png”）
自我筛选。blit（赢，（175230））
winRect=pygame.Rect（175230250164）
pygame.display.update（winRect）
完成=错误
虽然没有这样做：
self.CLOCK.tick（self.FPS）
mouse=pygame.mouse.get_pos（）
对于pygame.event.get（）中的事件：
如果event.type==pygame.QUIT：
self.STATE=0
完成=正确
如果代码中有219，则每次更新时都会重新绘制文本标签、文本框和名称：

self.SCREEN.blit(pygame.font.SysFont('comicsansms', 22).render("Enter your name :", True, Color.black), (210, 250))
# Textbox
pygame.draw.rect(self.SCREEN, Color.gray, (210, 310, 180, 35), 2)

但您没有清除内部的文本框。问题是您正在绘制一个未填充的矩形。绘制矩形的最后一个参数是宽度。您将其设置为2。因此它正在绘制一个未填充的矩形


如果您还添加了一个填充矩形（对于文本框内部），则每次都会清除该名称，并仅使用当前名称填充该名称

pygame.draw.rect(self.SCREEN, color_of_your_choice, (212, 312, 176, 31))

您必须调整x、y、宽度和高度，以适应外部框中稍微小一点的矩形
如果旧文本没有清除，那么我想它不会像应该的那样更新。您是否在删除字符时更新文本框？
