[Jass] Pick ever unit + matching

[Dr. Boom]

I have another question. I want to pick units in range that matching some conditions.

In GUI it's like that:

• Unit Group - Pick every unit in (Units within 1850.00 of (Position of Diablos Mother 0001 <gen>) matching ((((Matching unit) is dead) Equal to False) and (((Matching unit) belongs to an enemy of (Owner of Diablos Mother 0001 <gen>)) Equal to True))) and do (Actions)
  • Loop - Actions
    • Unit Group - Add (Picked unit) to FrozenLoveGrp

But now I want get it in Jass. If I convert this part from GUI to Jass it looks like:

function Trig_Frozen_Love_2_Func001001003001 takes nothing returns boolean
    return ( IsUnitDeadBJ(GetFilterUnit()) == false )
endfunction

function Trig_Frozen_Love_2_Func001001003002 takes nothing returns boolean
    return ( IsUnitEnemy(GetFilterUnit(), GetOwningPlayer(gg_unit_E000_0001)) == true )
endfunction

function Trig_Frozen_Love_2_Func001001003 takes nothing returns boolean
    return GetBooleanAnd( Trig_Frozen_Love_2_Func001001003001(), Trig_Frozen_Love_2_Func001001003002() )
endfunction

function Trig_Frozen_Love_2_Func001A takes nothing returns nothing
    call GroupAddUnitSimple( GetEnumUnit(), udg_FrozenLoveGrp )
endfunction

function Trig_Frozen_Love_2_Actions takes nothing returns nothing
    call ForGroupBJ( GetUnitsInRangeOfLocMatching(1850.00, GetUnitLoc(gg_unit_E000_0001), Condition(function Trig_Frozen_Love_2_Func001001003)), function Trig_Frozen_Love_2_Func001A )
endfunction

1) I don't think that this picking + matching stuff looks like this, if I write from the beginning each line in Jass or??

2) If it does, how should I keep it in my mind, that I always can type it without using hours of hours.

3) If not can someone (PLZ!) create the true Jass trigger with the matching stuff? So I can use it as an example, if I need more of them with different matching stuff or something like that.

function TriggerFrozenCondition takes nothing returns boolean
    return IsUnitEnemy(GetFilterUnit(), GetOwningPlayer(gg_unit_E000_0001) and GetUnitState(UNIT_STATE_LIFE) > 0.405
endfunction

function TriggerFrozenAction takes nothing returns nothing
    local unit u
    local location l = GetUnitLoc(gg_unit_E000_0001)
    local group g = CreateGroup()
    
    call GroupEnumUnitsInRangeLoc(g, l, 1800, Condition(function TriggerFrozenCondition))
    loop
        set u = FirstOfGroup(g)
        exitwhen u == null
        call GroupAddUnit(udg_FrozenLoveGrp, u)
        call GroupRemoveUnit(g, u)
    endloop
    call RemoveLocation(l)
    call DestroyGroup(g)
    set l = null
    set g = null
    set u = null

Should be something like this.

Ok somehow this sounds not difficult but I got 2 questions:

"GetFilterUnit ()" <-- what is this? Is that just the unit that is picked if all matching stuff is correct?

"0.405" what's the number at the end of your 2nd line? =O

GetFilterUnit() is MatchingUnit in GUI. The "picking" stuff is from "loop" to "endloop". I didn't use a new function. If you use another function with "ForGroup" picked unit is GetEnumUnit (if I remember correctly). 0.405 is the point when a unit dies. A unit will never directly reach 0 hitpoints. In the moment it dies, its hitpoints are 0.405. Don't ask me why. You could also ask for 0 hitpoints, but then you would pick dying units too. (but not dead ones)

GetFilterUnit() indeed returns what you call Matching Unit in GUI, while GetEnumUnit() returns the unit when you use a ForGroup loop.

"0.405" what's the number at the end of your 2nd line? =O

A unit's life cant go below 0.406, whenever a unit reaches 0.405 it will die. Thus, that number is for checking if a unit is alive. (Although this is really unreliable, a unit's life can still be changed after death)

e/ meh, too late :/

Ahh ok I understand =) and thanks that you create the Jass Trigger. Isn't hard to understand and I will start learning from it.

Thanks +rep =)
