«Жизнь» в моей игре не появится? pygame

Question

Итак, в моей памяти я получил это, когда вы нажимаете неправильную кнопку, вы теряете жизнь. И это работает! Потеряв 3 жизни, вы проиграете. Но проблема в том, что текст для жизни не появится в моей игре после ее запуска. Может ли кто-нибудь помочь мне? (Если вы заинтересованы в том, чтобы весь код, то вы могли бы смотреть на него здесь http://pastebin.com/rkBGC2rD)

Answer 1

В главном цикле, вы заполняете по всему фону с DISPLAYSURF.fill(bgColor), но не рисую livesRect снова.

Answer 2

Каждый раз, когда вы меняете lives вы должны оказывать снова

img = BASICFONT.render('I'*lives, 1, WHITE) 

и отображать его в каждом цикле

DISPLAYSURF.blit(img, livesRect)
