Question

我正在与Pygame合作一个游戏项目。我只是刚刚开始从事该项目，所以有点卡住了。我制作了三个文件，每个文件包含执行不同功能的代码。第一个文件“ alien_apocalypse.py ”包含类“ AlienApocalypse ”，该类用于启动和监视游戏中的用户事件，并包含一些导入的模块，例如游戏设置（这是第二个文件-' game_settings.py '）和一个类文件，其中包含游戏角色' knight.py '之一的所有属性。我正在尝试运行“ alien_apocalypse.py ”，该命令用于显示我的角色骑士和显示器的底部中间，但未显示任何内容。我在装有macOS Mojave的Mac上运行它，IDE是PyCharm。这些是文件：

文件1-“ alien_apocalypse.py ”：

import sys
import pygame
from game_settings import GameSettings
from knight import Knight


def run_game(self=None):
    """Start the main loop for the game"""
    while True:
        # Watch for keyboard and mouse actions
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()

        # Redraw the screen during each pass through the loop.
        self.screen_window.fill(self.settings.background_color)
        self.knight.blitme()

        # Make the most recently drawn screen visible.
        pygame.display.flip()


class AlienApocalypse:
    """Overall class to manage game assets and behaviour"""

    def __init__(self):
        """Initialize the game and create game resources"""
        pygame.init()
        self.settings = GameSettings()

        self.screen_window = pygame.display.set_mode((2880, 1800))
        pygame.display.set_caption("Alien Apocalypse")

        """Setting background color"""
        self.background_color = (230, 230, 255)

        self.knight = Knight(self)

    @classmethod
    def run_game(cls):
        pass


if __name__ == "__main__":
    """Make a game instance, and run the game"""
    ac = AlienApocalypse
    ac.run_game()

文件2- game_settings.py

class GameSettings:
    """This class stores all the game settings"""

    def __init__(self):
        """Initialize the game's settings attributes"""
        # Screen settings
        self.screen_width = 2880
        self.screen_height = 1800
        self.background_color = (230, 230, 255)

文件3 knight.py

import pygame


class Knight:
    """A class that manages the character knight"""

    def __init__(self, ac_game):
        """Initialize the knight and set its starting position."""
        self.screen_window = ac_game.screen_window
        self.screen_window_rect = ac_game.screen_window.get_rect()

        # Load the character - Knight image and get its rect.
        image_file = "/Users/johnphillip/Downloads/craftpix-891165-assassin" \
                     "-mage-viking-free-pixel-art-game-heroes/PNG/Knight" \
                     "/knight.bmp "
        self.image = pygame.image.load(image_file)
        self.rect = self.image.get_rect()

        # Start each new character at the bottom center of the screen.
        self.rect.midbottom = self.screen_window_rect.midbottom

    def blitme(self):
        """Draw the character at its current location."""
        self.screen_window.blit(self.image, self.rect)

我不知道是我的代码还是系统故障。

我到目前为止检测到的问题（现在显示窗口）：

您必须设置适当的视频驱动程序
然后您必须初始化pygame.display
您是在类（ac.run_game（））内部调用run_game（）函数，而不是另一个。
类中的run_game（）不执行任何操作（通过）
您必须将类中当前的run_game（）替换为外部类，以便可以访问“自身”（如变量和函数）。
如果不存在，则不能将self等于None作为默认值（self是类本身及其包含的所有内容，因此，如果将其等于None，则是在“杀死”自己（该类）！！！）

您的Alien_apocalypse.py可能看起来像这样：

import pygame
from game_settings import GameSettings
from knight import Knight

class AlienApocalypse:
"""Overall class to manage game assets and behaviour"""

def __init__(self):
    """Initialize the game and create game resources"""
    pygame.init()
    self.settings = GameSettings()

    drivers = ['windib', 'directx']

    found = False
    for driver in drivers:
        if not os.getenv('SDL_VIDEODRIVER'):
            os.putenv('SDL_VIDEODRIVER', driver)
        try:
            pygame.display.init()
        except pygame.error:
            print('Driver: {0} failed.'.format(driver))
            continue
        found = True
        break

    if not found:
        raise Exception('No suitable video driver found!')

    self.screen_window = pygame.display.set_mode((2880, 1800))
    pygame.display.set_caption("Alien Apocalypse")

    """Setting background color"""
    self.background_color = (230, 230, 255)

    self.knight = Knight(self)

def run_game(self):
    """Start the main loop for the game"""
    while True:
        # Watch for keyboard and mouse actions
        # for event in pygame.event.get():
        #     if event.type == pygame.QUIT:
        #         sys.exit()

        # Redraw the screen during each pass through the loop.
        self.screen_window.fill(self.settings.background_color)
        self.knight.blitme()

        # Make the most recently drawn screen visible.
        pygame.display.flip()

if __name__ == "__main__":
    """Make a game instance, and run the game"""
    ac = AlienApocalypse()
    ac.run_game()

pygame屏幕输出不显示
