python - 我的游戏中的“生命”不会出现吗？ pygame

所以，在我的记忆游戏里，当你按错按钮，你就失去了生命。这很管用！失去3条生命后，你就失去了。但这里的问题是，生命的文本一旦启动就不会出现在我的游戏中。有人能帮我吗（如果您对查看整个代码感兴趣，那么可以在这里查看它http://pastebin.com/rkBGC2rD）

                    score = 0
                    pygame.time.wait(1000)

        pygame.display.update()
        FPSCLOCK.tick(FPS)

最佳答案

每次更改lives时，都必须重新渲染

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

在每个循环中显示

DISPLAYSURF.blit(img, livesRect)
