[英]Blitting in new x position Pygame
Im writing a basic mouse dodge game and i need to blit little stars to dodge. 我正在编写一个基本的躲闪游戏,我需要变小星星来躲闪。 i made it so that once one star leaves the screen it blits it again at the top> that works but it blits it in the same x position
我做到了,一旦一颗星星离开屏幕,它就会再次在顶部将其变亮>起作用,但它会在相同的x位置变亮它
Here is the update code that moves the star: 这是移动星星的更新代码:
def update(self):
self.mouse_pos = pygame.mouse.get_pos()
(self.player_r.x, self.player_r.y) = self.mouse_pos
self.star_r.x = ran_x
self.star_r.y += 2
if self.star_r.y > 640:
self.star_r.y = 0
Here is where the star gets blitted: 这是恒星发白的地方:
def blitPlayer(self, screen):
screen.blit(background,(0,0))
screen.blit(self.player,(self.mouse_pos))
screen.blit(self.star,(ran_x, self.star_r.y))
I define ran_x
outside the class at the top like this: 我在类顶部定义
ran_x
,如下所示:
ran_x = random.randint(10,470)
What i think is happening is that when i run it ran_x is being defined by one random number and then keeping that number but i want it to change each time the star leaves the screen 我认为正在发生的是,当我运行ran_x时,它是由一个随机数定义的,然后保留该数字,但是我希望每次星星离开屏幕时它都会更改
Thanks in Advance!! 提前致谢!!

Then why not recompute ran_x here: 那为什么不在这里重新计算ran_x:
if self.star_r.y > 640:
self.star_r.y = 0
ran_x = new random number
