:rocks scene invalid and crashing. what's wrong with the batch code?

Question

Basically, I've been working on a game that allows you to create a world. It's extremely new and I've been working on it for about 30 minutes. The third-party external programs are cmdmenusel and CHOICE. At the rocks scene, ( :rocks ), when I click Expand, it crashes with a quick message. Can you please help me see what's wrong with my code?

Answer 1

You have goto mountain instead of goto mountains in the :rocks section.

Look just two lines beneath that goto to see your typo. There is no :mountain anywhere in your code. Only :mountains.

Hence, just change:

if %ERRORLEVEL% == 1 goto mountain

.. to:

if %ERRORLEVEL% == 1 goto mountains
