VScript

VScript, introduced in Left 4 Dead 2, is a virtual machine for scripting that acts as an abstract binding layer between the Source engine and external scripts. According to the Template:Game link, the following scripting languages are supported or could be in the near future:

• Squirrel
• Lua
• Gamemonkey
• Python

Script files are read from /scripts/vscripts/ inside the game directory.

To learn how VScripts are used, see VScript Fundamentals.
