How to detect if the ''Damage Source'' is not a unit?

[Ramza]

One of my custom abilities is using an action which damages the damage source. But it should only damage the damage source if it's an attack by a unit, and not, for example, poison damage or damage caused by some other buff.

Is there a way to this?

Edit: Only 1 unit can cast this ability (on itself). Any unit that damages the caster while under the effect of its ability, is affected by the damage source action.

If I get it right, you can add condition that will check if caster is teh target?

Yeah, that's no problem. What I don't get is how to detect if the damage source is an ability, a buff, or a unit.

Condition, attacking unit is "no unit"? Try it, sorry I don't have much time to test. Maybe it will work ^^

Impossible out right. You have to eithor make a custom damage system so you know where the damage comes from or use some sort of logical system to limit the possibilites of where damage comes from (not always 100% accurate).

If you set the damage source into a variable and then check Damage source not equal to no unit, it will return true if the damage source is a unit. I've used that before.

So first try what Vunjo said. If it doesn't works, try not equal to no unit.

ergh, if my logic is correct, "not equal to no unit" means that it is a unit?

check Damage source not equal to no unit, it will return true if the damage source is a unit.

Yes, just like I said. Is there any confusion? You can use if/then/else.

Merry christmas to you too.
