pygame中的函数无法正确生成输出

如何解决pygame中的函数无法正确生成输出

我有一个检查碰撞的功能

def collision_check1 (pboard_rect):
    if pboard_rect.colliderect(up_border_rect):
        pboard_rect = pboard.get_rect(topleft = (695,20)
        print("hi")

if game_active:
   collision_check1(pboard_rect)

在这里打印'hi'，但不会动我的pboard_rect要做的事情

编辑：

pboard_x = 695
pboard_y = 200



pboard = pygame.image.load("data/pboard.png")
pboard_rect = pboard.get_rect(topleft = (pboard_x,pboard_y))


screen.blit(pboard,pboard_rect) 

解决方法

def collision_check1 (pboard_rect):
    if pboard_rect.colliderect(up_border_rect):
        print("hi")
        return pboard.get_rect(topleft = (695,20))

if game_active:
   pboard_rect = collision_check1(pboard_rect)
