PyGame：什么都没有发生

Question

我正在 pygame 中制作游戏，但当我运行游戏时，什么也没有发生。出现一个黑框，但什么都不做，没有显示等。另外，让我烦恼的是 Python Shell 根本没有显示任何错误。这是主文件的代码：

import pygame
import sys
import random
import pygame.mixer
import math
from constants import *
from player import *

class Game():

    def __init__(self):

        #States (Not country states)
        self.game_state = STATE_INGAME

        #State variables
        #self.stateMenu = 

        #Screen
        size = SCREEN_WIDTH, SCREEN_HEIGHT
        self.screen = pygame.display.set_mode(size)
        pygame.display.set_caption('WIP')
        self.screen_rect = self.screen.get_rect()

        # Player
        self.player = Player(SCREEN_WIDTH / 2, SCREEN_HEIGHT / 2)

    def run(self):

        clock = pygame.time.Clock()

        if self.game_state == STATE_INGAME:

            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.exit()

            self.player_move()
            self.player.update()
            self.player.render(self.screen)

        clock.tick(100)

    def player_move(self):

        # move player and check for collision at the same time
        self.player.rect.x += self.player.velX
        self.player.rect.y += self.player.velY

Game().run()

我已经检查了很多次播放器文件，完全没有错误。好吧，不是我能看到的。感谢您的帮助！

你需要一个while-loop:

def run(self):

    clock = pygame.time.Clock()
    while True:
        if self.game_state == STATE_INGAME:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.exit()
            self.player_move()
            self.player.update()
            self.player.render(self.screen)

        clock.tick(100)
