So I wrote a guide on Steam on syntax colouring for Random Map Scripting for Notepad++, the scripting language to write random maps on Age of Empires. Essentially Notepad++ supports language syntax support, allowing you to make syntax easier on the eye.

So you’re writing a random map script, using standard default Notepad (that comes with Windows), it would look like this:

With Notepad++ and syntax colouring (User Defined Language Files) enabled, it will look like this:

So you get the drift, basically giving you a clearer visual on your code and possibly preventing errors in them as well.

You can see the guide here:
