Question

当我尝试弄平瓷砖时，它说“列表索引超出范围”。我不知道该怎么办，因为这是我的新手。

错误消息：

window.blit（tilemap.textures [tilemap.tilemap [row] [column]]，（column tilemap.tilesize，row tilemap.tilesize）） IndexError：列表索引超出范围

我试图更改mapwidth和mapheight的值，但这并没有解决问题。我有2个脚本。主图和图块映射。因此可能存在错误。注意（我已经在完整代码中初始化了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。该列表包含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]
    ]

因此图块地图的“宽度”和“高度”为4：

mapwidth = 4
mapheight = 4

但是您根本不需要该变量，因为您可以通过len()获得列表的长度：

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))

如果您想在地图上放置更多图块，则只需向tilemap:添加更多图块即可。

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])

是否有更好的方法在pygame中创建图块地图？
