有没有更好的方法在pygame中创建瓷砖地图

Question

当我尝试闪电我的瓷砖时，它说"列表索引超出范围"。我不知道该怎么办，因为我是新手。

错误信息：

window.blit(tilemap.textures[tilemap.tilemap[row][column]]， (column tilemap.tilesize， row tilemap.tilesize(( 索引错误：列出索引超出范围

我试图更改mapwidth和mapheight的值，但这并没有奏效。我有 2 个脚本。主图和瓦片映射。因此可能存在错误。注意(我已经在完整代码中启动了pygame，所以这不是问题(

main.py

import pygame as pg
# Importing files
import constants
import classes
import tilemap
# Functions
def draw_game():
    """ This function draws everything on the screen """
    global window, clock
    # The background
    window.blit(constants.img_background, (0, 0))
    # Tiles
    for row in range(tilemap.mapheight):
        for column in range(tilemap.mapwidth):
            window.blit(tilemap.textures[tilemap.tilemap[row][column]], (column*tilemap.tilesize, row*tilemap.tilesize))


    # Updating
    clock.tick(60)
    pg.display.update()

tilemap.py

import pygame as pg
import constants
GRASS = 0
WATER = 1


textures = {
    GRASS : pg.image.load("image\grass.png"),
    WATER : pg.image.load("image\water.png")
    }

tilemap = [
    [GRASS, GRASS, GRASS, WATER],
    [GRASS, GRASS, WATER, GRASS],
    [GRASS, WATER, GRASS, GRASS],
    [WATER, GRASS, GRASS, GRASS]    
    ]

tilesize = 40
mapwidth = 2
mapheight = 5

Answer 1

tilemap是一个

列表。该列表有 4 个元素，列表的每个元素也是一个包含 4 个元素的列表。

 tilemap = [
       [GRASS, GRASS, GRASS, WATER],
       [GRASS, GRASS, WATER, GRASS],
       [GRASS, WATER, GRASS, GRASS],
       [WATER, GRASS, GRASS, GRASS]
    ]

所以瓦片地图的"宽度"和"高度"是4：

mapwidth = 4
mapheight = 4

但是您根本不需要该变量，因为您可以通过以下len()来获取列表的长度：

for row in range( len(tilemap.tilemap) ):
    for column in range( len(tilemap.tilemap[row]) ):
        window.blit(tilemap.textures[tilemap.tilemap[row][column]],
                    (column*tilemap.tilesize, row*tilemap.tilesize))

如果要在地图上放置更多图块，则添加更多图块即可tilemap:

例如

tilemap = [
       [WATER, WATER, WATER, WATER, WATER, WATER],
       [WATER, GRASS, GRASS, GRASS, WATER, WATER],
       [WATER, GRASS, GRASS, WATER, GRASS, WATER],
       [WATER, GRASS, WATER, GRASS, GRASS, WATER],
       [WATER, WATER, GRASS, GRASS, GRASS, WATER],
       [WATER, WATER, WATER, WATER, WATER, WATER]
    ]
mapwidth = len(tilemap.tilemap)
mapheight = len(tilemap.tilemap[0])
