The XS Language

Already familiar with XS?

If you are already familiar with XS or a language similar to C/C++, you may want to jump directly to the AI Scripting part.

XS is the language used in AOE3 to control the AI, to create custom maps and to create custom triggers. Using the XS language, AOE3 modders can write code in a text file called a script (AI script, RM script, TR script), which the game can load, read and execute. The process of writing a script is called scripting.

This guide focuses primarily on AI scripting, but the knowledge acquired through this part of the guide is applicable to RM and TR scripting as well.
