pygame播放器沒有更新

所以我有這一小段代碼，它運行良好，但是當我移動角色時，無論角色在哪裏，都有它的背後的圖片。想象它拿着一支鉛筆並在一張紙上畫畫，那基本上就是它如何展現的。我不知道代碼錯在哪裏，否則它運行正常。它有任何其他方式來顯示播放器的這個問題。幫幫我？pygame播放器沒有更新

      pygame.display.update()

     pygame.display.update() 
     mainClock.tick(30)

您需要用白色填充屏幕以擦除舊圖像。在WindowSurface.blit(playerImage, playerRect)之前，在您的代碼中使用WindowSurface.fill(WHITE)在相同的縮進處。
