[Trigger] Unit unable to take damage

[Nightmare-]

How could I make a unit not take damage while casting a spell, but the enemy units can still attack the unit. For example, the spell im using is Omnislash, i dont want the enemies to run away when i cast this spell (because this spell currently make you invincible)

give him berserk and set the bonus damage negative. the unit wont take damage at all.

 

[Lord_BoNes]

Although, that is a viable solution, that way actual heals the caster.

 

[doom_sheep]

no, it doesnt.

 

[Lord_BoNes]

Setting it to 0, mean no damage. Setting it to a negative, means heal damage based on damage dealt.

 

[GhostWolf]

It heals only if the unit attacks, it has nothing to do with other units attacking him. As to whether it really stops damage, I don't know, although with all the lame bugs in warcraft I can believe it if someone says so.

 

[Lord_BoNes]

I've used it when trying to reduce damage taken. If damage taken increase is set to a negative value, then it heals whenever the unit is attacked, but I'm not entirely sure if setting it to 0 stops damage.

@doom_sheep: I've looked over the thread where I helped someone with "berserk". I was thinking of "defend".

BoNes bows to doom_sheep
Please accept my apologies, you are indeed correct.

Set magic and physical damage reduction to 0 and chance of reduction to 100%. Lord_BoNes's suggestion must work.

If the unit is a specific unit you could try a trigger...:

Event: "YourUnit" is dealt damage.
Condition:
Action: Set "YourUnit"s life to current life + "dealt damage"

But I am not sure what happens if the unit has ~1 hp and is attacked then...
(I think it dies because it's dead before the trigger runs, but I am not sure)

 

[Day-Elven]

He'll die.

 

[Lord_BoNes]

Actually, I'm pretty sure he won't. I've used that kind of approach in one of my maps for trigger based "misses" & "criticals".
If a unit is given back its hp before the frame following its "death", then it stays alive to fight another day.

Unit takes damage as well as unit is attacked work in strange ways. They actually work right before the damage/attack occurs, so yes, this trigger would work even if the unit's current health is lower than the damage being taken. If the unit's lost health is less than the damage, however, you have to wait a second and let the unit take the damage and then heal it. The only time in which this doesn't work is when the unit has less total HP than the damage of the spell, in which you have to do tricky JASS maneuvers.

what about giving the unit a 100% evsion?

No bad idea but I am not sure if you can remove the "miss".. and it looks stupid when there are 1000 of misses..

 

[Lord_BoNes]

@donut3.5: I've had it all working 100% right, with everything happening at "unit takes damage".

Unless you use a "damage-detection" approach, Enemy hero damage still happen. I found this out in the past when working on the ability I was talking about earlier. The "defend" approach works, yes, but not 100% effectively.

Evasion ability blocks only physical damage.
