[Trigger] How to prevent attacking?

[Elite Slayer]

Hello all,
Recently, I have been making a map (coming along very well, may I add), and I ran into a problem that has me seriously stumped. Having tried out all the methods I could think of, I've resorted to relying on your abundance of knowledge to help me out, please.

Okay, so here's what's wrong; basically, as a penalty, I want to make it so that a unit (to be specific, a ranged hero) can temporarily not be able to attack any enemy. (In other words, for a few seconds I want it so that that unit is not able to attack ANYONE...BUT his allies can).

Here's what I've tried so far; making a trigger that adds the "flying" classification to all the enemy units and removing the "able to attack flying units" from the unit...didn't work. Then, I made a trigger that whenever that specific unit is given the order to attack it automatically gives him the stop order, but that didn't work either (not too sure if I made some mistake in entering the order string, but I highly doubt it)
As if that's not enough, I then tried adding the "locust" ability to every enemy unit, but, believe it or not, that ability is not even on the add list, and the Ghost ability doesn't help, either. As a last resort, I made a trigger that made the owner player view the enemy as an ally, but he could still order the unit to attack any enemies manually.
So, right now...I'm downright confused.

Any tips, advice or solutions? It would be deeply appreciated.
Any answer-givers will receive +rep and credit in my map and, of course, my gratitude and the respect of others.

Thanks a lot,
Elite Slayer

it's simple

• Events
  • Unit - A unit is under attack
• Conditions
  • (Owner of (Attacked unit)) is equal to player with penalty
• Actions
  • Unit - Order (Attacking unit) to Stop

enable/disable this trigger when needed

if it's a one unit map you can just use player - disable ability attack for player and turn it on when you want too
