Unit orders in triggers

ok, my map, enemy heros spawn. they are ordered to attack a player unit, after it kills a player unit however, the hero stops in place and doesnt chase any other players. now, would the heros order right now be stop? or what, because i want a condition to be if the heros current orders are stop, order him to attack another random unit of random player in player group.

use this "order Attacking_enemy_hero to atack-move to position of attacked_player_unit"

Events
Unit - A unit Is issued an order with no target
Conditions
(Current order of (Triggering unit)) Equal to (Order(stop))
Actions
Unit - Order (Triggering unit) to Attack (Random unit from (Units in (Playable map area) owned by (Random player from (All players))))

i'll have to spoil it for you, but when the computer finishes the action, it doesn't use the "stop" order, and that trigger will fire for every unit issued a "stop" action...in other words, better use "attack move to position..."

EDIT: after reviewing it some more, i noticed that it will be ordered to attack ANY unit, including its own, since u used "all players" ...

actually ive looked at your suggestions and used none of them because they arent what im looking for. is there a way to detect if a unit isnt moving then?

if u want units killed in a certain order, one by one, try this

E:unit dies
C:dying unit equals to <your unit>
A: order <attacking unit> to attack <next unit>

that had nothing to do with my question. and it wouldnt work either because the player units revive. i want to know if there is ANY way to detect if a unit is not moving ie, not attacking or following to attack a player unit

hardly...try looking for "unit is idle" or such....
maybe u'll find it if u dig deep enough, cuz when u have workers that don't do anything, it shows u that "idle worker" pic...
i wonder if that could be returned thru a trigger somehow ?
