Pygame退格鍵輸入的文字未被清除。重疊而不是/

Question

產品圖更多，更清晰的問題： http://imgur.com/a/sbHax

如圖所示，我輸入了一些文字。決定退格，而不是我輸入的新文本重疊前一個。這是爲什麼發生？

新來的Pygame並堅持了這個問題時間過長已經:(

請幫助！我應該做的

什麼在你的代碼被重新繪製文本標籤，文本框，並在每次更新名稱：

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) 

但你不清除裏面的文本框的問題是要繪製未填充矩形繪製一個矩形的最後一個參數爲t。他的寬度。你有它設置爲2.所以它正在繪製一個矩形，但沒有填充。

https://www.pygame.org/docs/ref/draw.html#pygame.draw.rect

如果添加填充矩形，以及（在文本框內），它會在每次清除名，僅與當前名稱填充它。

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

你必須調整X，Y，寬度和高度，以佔略小的矩形，以適應外箱
