The cvar:

ms_dev_mode 1

Enables scripts in this folder. (Does not work on FN)



The Cvar should be set in your server/listenserver.cfg


You'll need a second cvar containing the script you want to test, eg:
ms_dynamicnpc "test_scripts/test_spider"
If you want to test multiple scripts, tokenize them thusly:
ms_dynamicnpc "test_scripts/test_spider;test_scripts/test_orc;test_scripts/test_skeleton"

You'll then be able to load them in the test_scripts map. 
(Type map test_scripts at console)

• Scripting_AllDocs.txt
- Is the original script write up by Dogg with some edits, but it is not as up to date as the ms.stx
