[Unsolved] Stationary/Mobile Unit Turning (Wc3 Turning)

[mattdraw]

I'm trying to figure out how to best replicate the unit turning system of Warcraft 3's, where unit's aren't able to simultaneously attack and turn. I've also noticed that the amount of frames it takes for a unit to buffer attack range, position, and movement takes more time. Stationary turning gives me what I want when I set it to 0 for the most part, but then the unit can only attack if it's target is in front of it.

Any ideas?
