It has been a long time since I have coded in Batch. There is a problem that I can't not figure out. I am making a Tic-Tac-Toe game, and when I have the player ENTER their choice via "set /p" and it goes through the process of setting the VARIABLE, which works fine. But what if they enter one that has already been selected. I do not know how to check the variable without having a bunch of if statements.

Thanks, Shiverbob

goto startYou technically do not need to use delayed expansion for all your other IF commands but you need it for the one I added.Here is a slightly more optimized version of your code.  I look forward to seeing your WIN logic.

goto startMy win solution requires if statements to be nested into each other. However, when I nest if statements together it crashes. Could it be the fact the the second if statement is false. It also crashes when i enter a different cord-nets.
And is it  possible to have a if "!var!" == "bah" || "bal"?

set /p c=Would you like to  have another game?(y/n):
if "!c!" == "n" exit

:xwin
cls
echo x Has won!!
set /p c=Would you like to  have another game?(y/n):
if "!c!" == "n" exit
if "!c!" == "y" goto presets
goto xwin


But when I used a for loop it would work however if you enter the last cordnets  and there is no winner YET it skips that and say whatever player is on there, they win.



is this what you need to do?

Code: [Select]if "!13!" == "x" if "!23!" == "x" (
  echo hello
  pause
)


A problem in your code is that the ( needs a space before it here:

Code: [Select]if "!23!" == "x"(
  echo hello
  pause
)You are overthinking it. In its simplest form you only need 8 IF statements and none of them need to be nested.And stop using delayed expansion for your variables when you dont have to use it.Last Night I finished the game, with delayed-expansion. All works fine. The reason I added delayed-expansion was for my multiplayer add-on... It runs with nested if and is about 100 lines of code. Thanks for the help!Seems like it would be appropriate to post your final code otherwise people who read this thread in the future will see it as unfinished. Depending on what you were trying to do I still believe you could code it without using delayed expansion. Quote from: shiverbob on January 06, 2015, 08:01:36 PM
