Question

我正在使用python在pygame中创建像pacman这样的游戏。我想将一个宝石的图像分配给jewel类。在迷宫中'J'代表jewel。所以，为了明确我如何将图像分配给宝石类，以便迷宫图中的所有J都是该图像？

宝石的课程是

class Jewel(object):
    """Class to hold Jewel sprite properties"""

    def __init__(self, pos):
        jewels.append(self)
        self.rect = pygame.Rect(pos[0], pos[1], 16, 16)

墙和迷宫的课程是

class Wall(object):
    """Class to hold Wall sprite properties"""

    def __init__(self, pos):
        walls.append(self)
        self.rect = pygame.Rect(pos[0], pos[1], 16, 16)

walls = [] #List to contain walls
jewels = []#List to contain Jewels

#!-----------------------Maze Layout----------------------!

#Table used to create the level, where W = wall
level = [
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
"W       J               W          JJJ           W",

#Draw the wall rects as shown in the table above
x = y = 0
for row in level:
    for column in row:
        if column == "W":
            Wall((x, y))
        if column == "J":
            Jewel((x, y))
        x += 16
    y += 16
    x = 0

#Draw walls and jewels
    for wall in walls:
        pygame.draw.rect(screen, (WHITE), wall.rect)

    for jewel in jewels:
        pygame.draw.rect(screen, (BLUE), jewel.rect)

只需将图片添加为对象的属性 - 例如，您可以使用__init__方法加载它们，如：

def __init__(self, pos):
    walls.append(self)
    self.rect = pygame.Rect(pos[0], pos[1], 16, 16)
    self.image = pygame.image.load("/path/to/image_file.png")

然后，在你的游戏循环中，而不是画一个矩形，调用传递图像的“屏幕”blit方法（pygame.Surface对象）：

for jewel in jewels:
    screen.blit(jewel.image, jewel.rect)

稍后当你在游戏中获得更多结构时，你应该将你的游戏对象放在专门的精灵组中，然后可以使用sprite的.image和.rect属性来当调用组draw方法时，将它们blit到屏幕。（查看http://www.pygame.org/docs/ref/sprite.html上的文档），而不是直接调用blit。
