Damage Reducing Shield

[Drazhar]

Hey guys. So i've been trying to make this spell work, what i want for it is; The caster casts a shield on a friendly unit, when this unit takes damage the damage is halved. However i've only been able to get it to half the damage of the caster if it's casted on him, i've tried other ways but none seem to work. When changing "triggering unit" to "Target unit of ability being cast" it didnt halve the damage, instead healed the last unit that had the buff for the damage the unit that was that had the buff that taking the actual damage.

        • Unit - Set life of (Picked unit) to ((Life of (Picked unit)) + ((Damage taken) / 2.00))
      • Else - Actions
        • Do nothing

Right now I was messing around with picked unit and unit groups but it wasn't working. I'm running out of ideas for this : / would very much appreciate help if possible.

The unit can die before getting life back. You need to revive it and calculate it's correct health.

Thank you Maker, you rock. Though I had to change

"(Target unit of ability being cast) is in group) equal to false" to true, it wasnt working otherwise.

 

[Maker]

Post the code, please.

Although, i've been realising something... It halves the damage but sometimes it doesnt for some reason... for example, if the unit is taking too much it doesn't seem to take it's health down, well it takes it down by 2-4 health but it just goes up? Yet it doesnt stop them from dying...

Shield group is a global group. Don't remove/create it with triggers.

      • Then - Actions
        • Unit Group - Add (Target unit of ability being cast) to Shieldgroup
        • Trigger - Add to Cast <gen> the event (Unit - (Target unit of ability being cast) Takes damage)
      • Else - Actions

For the dying part, you need some math. Let's say the unit has 20 health and it take 30. It dies before the +health takes effect. Then you revive the unit and set it's health to 20 - 30 / 2 = 5.

You should check whether the unit should stay dead before reviving it.

Okay so I just experimented - I had a unit with 30 chaos damage and a unit with 50 health and no health regen. I got the unit with 50 health down to 20 health using a unit that did 5 damage and then made the unit with 30 chaos damage attack him, he had the buff of course and survived with 4 health. Where the extra 1 damage came from beats me, but thats roughly 30 divided by 2. So I think we're good, I think the healing effect responds fast enough to stop the death

- Just tested 2 more times, and the last time with a unit without the shield on 20 health as well, he died instantly while the shield guy lived with 5 health

Nevertheless, thanks for the help again Maker, very much appreciated. Rep'd you

its because the event A unit takes damage actually fires before the unit gets damaged... so he is healed first before he gets damaged... which makes your shield a lifesaver... ^_^

That's a shocker...


Anyway, thanks for spreading this fact to others that reads this post.

Awesome, glad I experimented with it

Awesome, glad I experimented with it

and also be careful with it coz it can cause infinite loops if you use the action Unit - Damage target in the actions of a trigger with the event Unit - A unit takes damage... ^^
