Im trying to find a list of init commands that can be placed in the units editing screen, I have searched but it doesnt seem like their is a compiled list any where. Im not looking for a specific command, just wandering what is available.
You can put almost any code into a unit's init line. I do not think you will find a specific list. This page in the Biki breaks down different scripting commands by functionality that you may find useful:
Init lines often have code that manipulations inventory like addWeapon, removeAllWeapons, etc. It is often also use to add event handlers or user actions to that specific unit.
There is a forum just for mission editing questions here.
