But somehow, the final product does not work as expected.
If somebody has a different way of doing this, let me know. For now, here is the non-working code. I'll try to figure out the problem myself, but any help I have would be greatly appreciated.
Code: Select all
@echo off
setlocal enabledelayedexpansion
for /l %%g in (0,1,15) do set board[%%g]=0
call :tilespawn
call :tilespawn
:startloop
cls
echo !board[0]! !board[1]! !board[2]! !board[3]!
echo !board[4]! !board[5]! !board[6]! !board[7]!
echo !board[8]! !board[9]! !board[10]! !board[11]!
echo !board[12]! !board[13]! !board[14]! !board[15]!

Sample starting configuration (determined randomly):

Expected output:

Sample starting configuration:

You should know what this is code for by now.
EDIT: I have found out the problem is that the IF blocks did not work as expected. When I go through them, the value of e never changes, despite there being a change to e right after the if is entered. Help?
