本文为大家分享了pygame游戏之旅的第5篇，供大家参考，具体内容如下
在游戏中添加显示文字：
这里自己定义一个crash函数接口：
|
1
2
|
def crash(): message_diaplay('you crashed') |
然后实现接口函数message_display(text)

def message_diaplay(text): largetext = pygame.font.font('freesansbold.ttf',115) textsurf, textrect = text_objects(text, largetext) textrect.center = ((display_width/2),(display_height/2)) gamedisplay.blit(textsurf, textrect) pygame.display.update() time.sleep(2) game_loop() |
在这其中定义了一个函数text_objects(text, largetext)，最后实现这个函数即可
|

|
def text_objects(text, font): textsurface = font.render(text, true, white) return textsurface, textsurface.get_rect() |
