[JASS] Make unit fly backwards

[Titanhex]

I loooked through the tutorials but couldn't find one on how to do this.

Basically I'm making a skill called Uppercut. The hero hits the unit, and he flies up and back a small ways. I have http://www.hiveworkshop.com/forums/f413/knockback-unit-35545/ in my map already, which I can use for the knockback effect. However it's the fly effect that I'm confused on implementing. I just know it involves the Crow Form ability.

You add the crow form ability in a hidden spellbook, that allows you now to change the unit's flying height. then you just change the unit's flying height simaltenously to pushing it back

Wait, what?

Do I have to do anything with the crow form ability, or does he just have to have it in the book and that's it?

How do I set up the duration and direction that he flies? What if I want to do it AOE?

I really need more information to do this, but thanks for trying.

The idea is, that once a unit has the ability "Crow Form(Medivh)" it is able to have its flying height changed, even if it is a ground unit. So, knowing this you can just change the flying height of your unit over time (like a jump). Since you have created a pushback, I trust that you are capable of adding such a minor feature to it.

You can remove the ability right after you give it, in case you don't like your ability bar showing it.
