Я новичок в Python и Pygame, и мне было интересно, может ли кто-нибудь помочь мне понять, как создать карту плиток для размещения «спрайтов» плитки для моей игры. Я немного просмотрел его и ничего не могу найти. У меня есть некоторый код, который, возможно, даст вам представление о том, куда я иду с этой игрой (конечно, это не работает). Кто-нибудь может помочь?

     import pygame, sys, random
    from pygame.locals import *

    # constants representing colors
    RED = (255, 0, 0)
    GREY = (128, 128, 128)

    #constants representing the different resources
    LAVA = 0
    STONE = 1

    # a dictionary linking the resources to textures
    colors =  {
                LAVA : RED,
                STONE : GREY,
                }

    # a list representing our tilemap

Я ожидал, что будет сетка размером 30×30 плиток с границей из 2 оранжевых «лавовых» плиток вдоль всех сторон и центром из серых «каменных» плиток в центре. Но вместо этого я просто получаю полный экран красного цвета: (.

Вы перезаписываете tilemap эту строку через несколько строк после ее инициализации:

 tilemap = [[LAVA for w in range(MAPWIDTH)] for h in range(MAPHIGHT)]
