雪碧衍生物0,0，并不会更新位置

Question

我遇到了一个相当恼人的问题，我希望我们中间有人可能有关于它的知识，可能可以帮助。

问题是，创建的代表玩家的精灵会卡在它的重生位置。 btw的产卵位置并不是我告诉它产卵的地方，并且不会接受坐标在其他地方产卵，它只会在那里产卵，恰好在屏幕的左上角。我让我的程序在运行时持续打印它的位置以及改变坐标的命令，并且它接收应该更新的信息，精灵不会移动。它的行为方式就好像我碰到了一堵不可逾越的墙壁。

relavent巨蟒/ pygame的代码：

class Player(pygame.sprite.Sprite): 
    #This class represents the Player. 

    def __init__(self): 
     #Set up the player on creation. 
     # Call the parent class (Sprite) constructor 
     pygame.sprite.Sprite.__init__(self) 
     #draws on the sprite 
     self.image = pygame.image.load("spaceship.png").convert_alpha() 
     # scales sprite based on resolution 
     self.image = pygame.transform.scale(self.image,(width // 8,height // 7)) 

     self.rect = self.image.get_rect() 
     self.rect.y = y     #sets initial spawn point to x and y which are variables 
     self.rect.x = x     # set to the middle of the screen earlier in the program 


    def update(self): 
    # Update the player's position. # 



     # Set the player's x,y coordinates to that of movex, movey 
     self.rect.x = movex #movex and movey are a means for changing x and y via player input 
     self.rect.y = movey 

....调用播放器类.....

player = Player() #creates the player sprite that gets manipulated via the player class 
player_list.add(player) #adds the new player to both lists to aid in tracking and updating 
all_sprites_list.add(player) 

......的意思，而游戏功能里面。 ...

all_sprites_list.update() #forces all sprites within the list to refer to their class's update   function 

all_sprites_list.draw(screen) #auto magically draws all the new sprites 

pygame.display.flip() #actually renders the updated imagery for entire program. 

这应该是任何有关的问题精灵。我当然可以提供进一步的信息，如果它被要求的话，我只是不想在这里发布大量的代码块，因为它可能会吓跑人们。 ：P

编辑：x和y是初始设置为全局变量是高度// 2和宽度// 2的高度和宽度被用于分辨率

movey和的Movex被全局设置为0，但当游戏在游戏功能循环中运行时更新。 示例代码movey，的Movex：

if event.type == KEYDOWN: #ship movement 
      if event.key == K_LEFT: 
       movex=-6 
      if event.key == K_RIGHT: 
       movex=+6 
      if event.key ==K_UP: 
       movey=-6 
      if event.key ==K_DOWN: 
       movey=+6 
      if event.key == K_a: 
       movex=-6 
      if event.key == K_d: 
       movex=+6 
      if event.key ==K_w: 
       movey=-6 
      if event.key ==K_s: 
       movey=+6 
x += movex 
y +=movey 

UPDATE !!!!!!

self.rect.x = movex #movex and movey are a means for changing x and y via player input 
self.rect.y = movey 

这一行简单地需要的是：

self.rect.x += movex #movex and movey are a means for changing x and y via player input 
self.rect.y += movey 

在添加加的等号之前通过加入movey，的Movex代替改变self.rect（X，Y）的值。重复地分配给他们的价值。

您需要在您所使用的变量（x和y）来传递：做同样的事情为的Movex，movey

def __init__(self,x,y): 
     #Set up the player on creation. 
     # Call the parent class (Sprite) constructor 
     pygame.sprite.Sprite.__init__(self) 
     #draws on the sprite 
     self.image = pygame.image.load("spaceship.png").convert_alpha() 
     # scales sprite based on resolution 
     self.image = pygame.transform.scale(self.image,(width // 8,height // 7)) 

     self.rect = self.image.get_rect() 
     self.rect.y = y     #sets initial spawn point to x and y which are variables 
     self.rect.x = x
