所有这些坐标中的代码都陷入困境！

如果有某种方式可以将妖精的一切都存储在一起，保持其整洁，并允许其作为参数传递或存储在列表中，该怎么办？

那么我们对地精有什么了解呢？

可以很容易地将其放入python list（如数组）中：

goblin1 = [ 0, 0, walkLeft ]
goblin2 = [ 1, 0, walkLeft ]
...

这些可以保存在另一个列表中：

goblins = [ goblin1, goblin2, ... ]

简化drawPieces()：

# window border constants
X_BORDER = 40
Y_BORDER = 40

drawPieces( screen, goblin_list ):
    global X_BORDER, Y_BORDER

    # paint background white
    screen.fill( ( 255,255,255 ) )  

    # draw each goblin in the list
    for single_goblin in goblin_list:
        # copy the three parts of the goblin's info from the list
        board_x, board_y, bitmap = single_goblin

        # convert game grid-position to screen-position
        screen_x = X_BORDER + ( board_x * 32 )
        screen_y = Y_BORDER + ( board_y * 33 )
        screen.blit( bitmap, ( screen_x, screen_y ) )

    # flush the updates to the display
    pygame.display.flip()

还有PyGame sprites，它们是软件对象，因此它们既封装了对象的变量，又封装了与之配合使用的函数。

class GoblinSprite( pygame.sprite.Sprite ):
    def __init__( self, bitmap, board_position ):
        self.position = board_position
        self.image    = bitmap
        self.rect     = self.image.get_rect()
        self.setScreenPosition()

    def setScreenPosition( self ):
        global X_BORDER, Y_BORDER
        screen_x    = X_BORDER + ( self.position[0] * 32 )
        screen_y    = Y_BORDER + ( self.position[1] * 33 )
        self.rect.x = screen_x
        self.rect.y = screen_y
        return (screen_x, screen_y)

PyGame网站上有一个简短的tutorial。
