Question

我的游戏存在问题，这不是一个错误，而是一个问题。我正在使用spritesheets制作我的游戏并使用for循环自动调用我的Platform类。但是，当我尝试调用平台类时，它只显示整个spritesheet。类平台或level_1可能存在错误，但我不确定它是什么。如果你有pygame，请帮助我。 An image of what is happening

import pygame
# Colours + Global constants
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0,  0, 255)
BLACK = (0, 0, 0)
RANDOM = (12, 211, 123)
WIDTH = 800
HEIGHT = 600
SIZE = (WIDTH, HEIGHT)


# CLASSES
# Block is the common platform

平台类：

class Platform(pygame.sprite.Sprite):
    def __init__(self, display, x_screen, y_screen, x_sheet, y_sheet, height, length):
        super().__init__()

        self.image = pygame.image.load("tiles_spritesheet.png")
        self.rect = self.image.get_rect()
        display.blit(self.image, (x_screen, y_screen), (x_sheet, y_sheet, height, length))

Level_1课程：

class Level01(Level):
    def __init__(self, player1, monster, display):
        # Initialise level1
        super().__init__()
        # Level01 things
        block = Block(WIDTH*3, 3, BLACK)
        Level.all_things = self.all_things

        self.sprites.add(player1, monster)
        self.platforms.add(block)
        self.all_things.add(player1, block, monster)

        theLevel = [[1, HEIGHT, 0, 0],
                    [1, HEIGHT, WIDTH*3, 0]]

        level = [[600, 400, 710, 0, 70, 70]]

        for platform in theLevel:
            block = Block(platform[0], platform[1], RED)
            block.rect.x = platform[2]
            block.rect.y = platform[3]
            self.platforms.add(block)
            self.all_things.add(block)

        for goodPlatform in level:
            platform = Platform(display, goodPlatform[0], goodPlatform[1], goodPlatform[2], goodPlatform[3], goodPlatform[4], goodPlatform[5])
            self.platforms.add(platform)
            self.all_things.add(platform)

Group使用self.image和self.rect到blit元素

使用pygame.Surface.subsurface和(x_sheet, y_sheet, height, length)创建地下 - 并分配给self.image
将(x_screen, y_screen, height, length)分配给self.rect

class Platform(pygame.sprite.Sprite):

    def __init__(self, display, x_screen, y_screen, x_sheet, y_sheet, height, length):
        super().__init__()

        self.tiles = pygame.image.load("tiles_spritesheet.png")

        self.image = self.tiles.subsurface(pygame.Rect(x_sheet, y_sheet, height, length))
        self.rect = self.image.get_rect(x=x_screen, y=y_screen)


        #display.blit(self.image, self.rect)

所有spritesheet都显示在屏幕
