矩阵中的列表索引超出范围错误

Question

我正在尝试根据块周围的块对块应用不同的纹理，但在执行代码时出现“列表索引超出范围”错误。

我已经搜索并尝试解决问题几个小时，我认为我做的不对，但我想不出正确的方法。

level = [
#                     1 1 1 1 1 1 1 1 1 1 2 2 2
# 0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2
[ 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],#0
[ 0,0,0,0,0,0,0,0,0,1,0,1,0,0,0,0,0,1,1,1,0,0,0],#1
[ 0,0,0,0,0,0,0,0,0,0,0,1,0,1,1,1,0,1,1,1,0,0,0],#2

您的level 矩阵有 9 行 23 列。当你有像

这样的条件语句时

if level[i][j-1] == 1 and level[i-1][j] == 1 and level[i][j+1] == 1 and level[i+1][j] == 1:

在j = 22 或i = 9 的情况下，您尝试访问level[i][j+1] 不存在的索引，回忆一下Python 中的列表索引从0 开始。我不清楚是什么您的代码正在执行，但一个明显的补救措施是减少您的 ranges，这样您就不会尝试在最终迭代中访问不存在的索引。
