当对象在数组中时如何将玩家与对象碰撞？

Question

注意： platforms是我定义灯光尺寸的模块，在这里我只是使用x和y将对象放入屏幕level坐标。

如何制作播放器和对象＆＃39; LIGHT＆＃39;在我的游戏中碰撞？

播放器代码：

class Player(pygame.sprite.Sprite):
    change_x = 0
    change_y = 0
    walking_frames_l = []
    walking_frames_r = []
    direction = "R"
    level = None

    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        sprite_sheet = SpriteSheet("p2_jump.png")
        image = sprite_sheet.get_image(0, 0, 66, 90)
        self.walking_frames_r.append(image)
        image = sprite_sheet.get_image(0, 0, 66, 90)
        image = pygame.transform.flip(image, True, False)
        self.walking_frames_l.append(image)
        self.image = self.walking_frames_r[0]
        self.rect = self.image.get_rect()

对象代码：

class Level_01(Level):
    def __init__(self, player):
        Level.__init__(self, player)
        self.background = pygame.image.load("120111.png").convert()
        self.background.set_colorkey(setup.WHITE)
        self.level_limit = -2200
        level = [[platforms.GRASS_LEFT, 500, 500],
                 [platforms.GRASS_MIDDLE, 570, 500],
                 [platforms.GRASS_RIGHT, 640, 500],
                 [platforms.GRASS_LEFT, 800, 400],
                 [platforms.GRASS_MIDDLE, 870, 400],
                 [platforms.GRASS_RIGHT, 940, 400],
                 [platforms.GRASS_LEFT, 1000, 500],
                 [platforms.GRASS_MIDDLE, 1070, 500],
                 [platforms.GRASS_RIGHT, 1140, 500],
                 [platforms.GRASS_LEFT, 1120, 280],
                 [platforms.GRASS_MIDDLE, 1190, 280],
                 [platforms.GRASS_RIGHT, 1260, 280],
                 [platforms.GRASS_LEFT, 1870, 400],
                 [platforms.GRASS_MIDDLE, 1940, 400],
                 [platforms.GRASS_RIGHT, 2010, 400],
                 [platforms.GRASS_LEFT, 2080, 280],
                 [platforms.GRASS_MIDDLE, 2150, 280],
                 [platforms.GRASS_RIGHT, 2220, 280],
                 [platforms.GRASS_LEFT, 2350, 450],
                 [platforms.GRASS_MIDDLE, 2420, 450],
                 [platforms.GRASS_RIGHT, 2490, 450],
                 [platforms.LIGHT1, 570, 430],
                 [platforms.LIGHT2, 870, 250],
                 [platforms.LIGHT3, 1190, 150],
                 [platforms.LIGHT4, 1940, 350],
                 [platforms.LIGHT5, 2200, 95],
                 [platforms.LIGHT6, 2420, 350],
                ]
