pygame中的绘图问题

Question

我正在尝试在 pygame 中制作一个相对简单的游戏：

import pygame as pg
import sys
import math

# game settings
RES = WIDTH, HEIGHT = 1600, 900
FPS = 60

PLAYER_POS = 1.5, 5 #mini_map
PLAYER_ANGLE = 0
PLAYER_SPEED = 0.004
PLAYER_ROT_SPEED = 0.002


# initializes game
class Game:
    def __init__(self):
        pg.init()
        self.screen = pg.display.set_mode(RES)
        self.clock = pg.time.Clock()
        self.delta_time = 1
        self.new_game()
        self.initialize_world_map = self.map.initialize_world_map

    def new_game(self):
        self.map = Map(self)
        self.player = Player(self)

    def update(self):
        self.player.update()
        pg.display.flip()
        self.delta_time = self.clock.tick(FPS)
        pg.display.set_caption(f'{self.clock.get_fps() :.1f}')
        self.map.draw()

    def draw(self):
        self.screen.fill('black')
        self.map.draw()
        self.player.draw_player()

    def check_events(self):
        for event in pg.event.get():
            if event.type == pg.QUIT or (event.type == pg.KEYDOWN and event.key == pg.K_SPACE):
                pg.quit()
                sys.exit()

    def run(self):
        while True:
            self.check_events()
            self.update()
            self.screen.fill('black')
            self.map.draw()
            self.player.draw_player()

它应该生成 mini_map 列表框中的所有数字，但它只是在左上角附近生成几个框。我尝试重写类映射中的函数并稍微切换一下变量，但没有成功。我真正的问题不是它没有运行，而是我不明白为什么。任何帮助将不胜感激。

self.initialize_world_map”是一个嵌套列表，其中包含地图中的值。绘制网格时必须迭代网格的行和列。

class Map:
    # [...]

    def draw(self):
        for j, row in enumerate(self.initialize_world_map):
            for i, value in enumerate(row):
                if value:
                    pg.draw.rect(self.game.screen, 'white', (j * 100, i * 100, 100, 100), 2)

请注意，

get_map

根本不执行任何操作，因为它仅将网格中的值分配给自身
