[Help] Is there an ability that...

Tide-Arc Ephemera	... gives a solid reduction to spell damage? I know there's stuff like Elune's Grace but is that's in percentages... is there something that gives a solid lowering in damage from spells?

Castlemaster	Closest that I can think of is the Spell Shield that banshees have. It absorbs X amount of spell damage.

Gorman	Sure, do that if you want to reapply the buff any and everytime the unit takes damage.

It really wouldn't be that hard, though a bit inefficient and robust:

JASS:

library SpellReduction initializer Init
    globals
        private integer DUMMY_ID = 'h000'
        private integer REDUCTION_ABILITY_ID = 'A005'

        private trigger ApplyTrig = null
        private unit Dummy = null
    endglobals

    private function True takes nothing returns boolean
        return true
    endfunction

    private function Apply takes nothing returns boolean
        local unit U = GetTriggerUnit()

        call SetUnitX(Dummy, GetUnitX(U))
        call SetUnitY(Dummy, GetUnitY(U))
        call IssueTargetOrder(Dummy, "spellshield", U)

        if GetTriggerEventId() != EVENT_UNIT_DAMAGED then
            call TriggerRegisterUnitEvent(ApplyTrig, U, EVENT_UNIT_DAMAGED)
        endif

        set U = null
        return false
    endfunction

    private function Enum takes nothing returns nothing
        local unit U = GetTriggerUnit()

        call SetUnitX(Dummy, GetUnitX(U))
        call SetUnitY(Dummy, GetUnitY(U))
        call IssueTargetOrder(Dummy, "spellshield", U)
        call TriggerRegisterUnitEvent(ApplyTrig, U, EVENT_UNIT_DAMAGED)

        set U = null
    endfunction

    private function Init takes nothing returns nothing
        local group G = CreateGroup()
        local region R = CreateRegion()

        call RegionAddRect(R, bj_mapInitialPlayableArea)

        set ApplyTrig = CreateTrigger()
        call TriggerRegisterEnterRegion(ApplyTrig, R, Condition(function True))
        call TriggerAddCondition(ApplyTrig, Condition(function Apply))

        set Dummy = CreateUnit(Player(14), DUMMY_ID, 0.00, 0.00, 0.00)
        call UnitAddAbility(Dummy, REDUCTION_ABILITY_ID)
        call UnitRemoveAbility(Dummy, 'Amov')

        call GroupEnumUnitsInRect(G, bj_mapInitialPlayableArea, Condition(function True))
        call ForGroup(G, function Enum)

        call RemoveRegion(R)
        call DestroyGroup(G)
        set R = null
    endfunction
endlibrary

Although... that would not work well with periodic damage.

As a workaround I'd suggest doing the following:
-Catch the unit gets damaged event, and incase the unit is protected prevent 100% of the damage(using hardened skin and a 0. timer)
-Deal the Damage you want to be dealt to the unit yourself
For this method, though, you need some kind of damage detection. If you aren't alreayd using one I suggest you use the one from moyack since it still allows for orb abilities and stuff.
Sorry, don't know of a better way to do this.

cohadar	You can always use spell shield, if you set it's life to 300 for example it will absorb 300 damage and then dispel itself. Having damage detection system solves 80% of this type of problems btw.

darkwulfv	Yeah but a damage detection system wasn't made for, say, a single spell or unit. If he's just doing this for a single unit, why would he want to download an entire damage detection system? And Spell Shield was already suggested I believe, and the shield will dispel, not offering a solid reduction consistantly like he wanted.

Blubb-Tec	This probably won't be the only thing he'll need a damage-system for in his map(I doubt that for 90% of the maps), and even if it was, it would still pay off. Because e.g. casting spell shield every time the unit would take damage, imagine that in a 0.04 dmg loop or something.. and then imagine like 5 units having that shield..

Tide-Arc Ephemera	I think I might need to change my signature back... I can't use any "magical" Jass because I use Mac OS X.

Hydrolisk	I'd personally suggest a really long duration Spell Shield, that would be recast whenever the unit takes damage/becomes the target of a spell/just before the duration ends/gets dispelled.

07-25-2008, 05:52 PM	#12
darkwulfv	That's been suggest 100 times, and apparently it would be slow as hell on spells that did damage every .04 seconds or whatever.

Pyrogasm	Right after I posted that code, Tide, I left for vacation. In the car I realized that you can't use vJASS code and then I smacked my head with a book XD Go me for remembering.
