How to get units in front of the caster

[FarAwaY]

Well actually I have 2 questions.

1) Im making a triggered spell in which I want to damage units that are in front of the caster (with a suitable range, of course) so how do I do it?

2) I want a potion that heals a percentage of the unit's max hp/mana instead of a fixed value but I cant seem to find an item ability that does that. Does such an ability exist or do I have to trigger it?

Speaking of which, I tried triggering it but it turned out a little wrong. I tried doing Set Life to Life of triggering unit + [30/100 X Max Life of Unit]...but it didnt work.

1. why you dont use a shockwave instead of making trigger?

2. life regeneration aura can be set to heal % of HP but i dont know if it can be used for healing potion. if not - show ur trigger

My trigger is very simple. I have already said it in my previous post.

A Unit Uses an Item

Item Being Manipulated = Life Potion

Set Life to Life of triggering unit + [30/100 X Max Life of Unit].

For the 1) Answer, I assume you're familiar with triggered spells? Spells that use dummy units....scaled up for better looking effects and stuff? I am making a triggered spell so I cant use shockwave skill.

you would pick all units within range of the caster matching that their angle between points of the caster and the picked unit is within X degrees of the facing angle of the caster, and then do damage or whatever

Ah....could you give me a full trigger code so I can see how it exactly works?

for heal use this

• Unit - Set life of (Hero manipulating item) to ((Percentage life of (Hero manipulating item)) + xxx{=%value of health u want to be healed})%

Ok thanks. What about the other one?

 

[kaboo]

about that i have no idea, never done smthing like that

i made a similar trigger in this thread..

function StormBoltConditions takes nothing returns boolean
    return GetSpellAbilityId() == 'ACbf'  //Still using Breath of Frost..
endfunction

function TargetConditions takes nothing returns boolean
    if ( IsUnitType(GetFilterUnit(), UNIT_TYPE_MECHANICAL) == true ) then
        return false
    endif
    if ( GetTriggerUnit() == GetFilterUnit() ) then
        return false
    endif
    return true
endfunction

function FindTarget takes unit u, real r returns unit
    local real x = GetUnitX(u)
    local real y = GetUnitY(u)
    local real xx
    local real yy
    local real angle
    local real face = GetUnitFacing(u)
    local real absmod
    local group g = CreateGroup()
    local unit t = null
    local real dis = r*r+1

    call GroupEnumUnitsInRange(g, x, y, r, Condition(function TargetConditions))
    loop
        set u = FirstOfGroup(g)
        exitwhen u == null
        call GroupRemoveUnit(g, u)
        set xx = GetUnitX(u)
        set yy = GetUnitY(u)
        set angle = Atan2(y-yy,x-xx) * bj_RADTODEG
        set absmod = ModuloReal(RAbsBJ(angle-face), 360)
            if absmod > 135 and absmod < 225 then
                if dis > (xx-x)*(xx-x)+(yy-y)*(yy-y) then
                set dis = (xx-x)*(xx-x)+(yy-y)*(yy-y)
                set t = u
                endif
            endif
     endloop
     call DestroyGroup(g)
     set g = null

     return t
endfunction

function StormBoltActions takes nothing returns nothing
    local unit u = GetTriggerUnit()
    local real r = 6000
    local unit t = FindTarget (u,r)
    if t != null then
        call SetUnitExploded(t, true)
        call KillUnit(t)
    endif
endfunction

//===========================================================================
function InitTrig_StormBolt takes nothing returns nothing
    local trigger t = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( t, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( t, Condition( function StormBoltConditions ) )
    call TriggerAddAction( t, function StormBoltActions )
endfunction
