The first you thing you need to is familiarize yourself with the basic tools in the editor. ElectroCute wrote a pretty useful and accessible guide for this. I'd highly recommend working your way through it to learn the basic tools.

The mission editor page on the Arma 3 wiki, also details the basic tools:

Here at 1Tac we use our own version of the F3 framework to make things easier for mission makers. The F3 framework is a mission template with many useful features. It is designed to used as the starting point of a mission, you then delete/customize/disable stuff to fit your mission. Following this tutorial would be best.

Note: we use our own version of F3 hosted on github - You can download it by clicking download zip on the right side.

Employing effective AI is a bit more complicated. I wrote a guide that introduces how to use and compares some scripted solutions for AI in coops. https://docs.google.com/document/d/1aIK … sp=sharing

This document details the 1Tac mission standards, as well as how to get your mission uploaded to our servers.
