[Trigger] Armor of unit action?

[I_LOVE_SWE]

Im creating a spell called Heavy Armor. Basicly it reduces the movement speed of the targeted by 10 for every armor point. But i cant find a way to set a variable to the units armor.

EDIT: Is there a way to detect current damage of hero then? Or give for example +10 damage on every attack?

There is no native to detect a unit's armor, e.g. GetUnitArmor()
There are a couple of systems that can detect that and basically, they just cause damage to a unit and then heal it back to detect the damage dealt. Up to the damage dealt and a formula, you can find the armor.

One way is to damage a unit, feed the difference into the armor formula, instantly restore the damage, and figure out a unit's armor that way, like Pharaoh said.

Another possibility is to set all armor for units in your map to zero then add it with triggers by doing something like adding a many-leveled +1 item armor ability to units, setting the level to whatever amount of armor you want, then detecting the level of that ability.
