Targeting a triggered ability

[Regalth]

I'm having trouble with one of my new abilities. When used, it's supposed to put every unit around the target to sleep. I tried using dummy units, like this:

Events: A unit Finishes casting an ability
Conditions: Ability being cast equal to (Black Night)
Actions: Pick every unit in (Units within 500 of (Target order of ability being cast)) and do actions:
Create one Black Night Dummy Unit for (Owner of (Triggering unit)) at
position of (Picked unit)) facing default building degrees.
Order (Last created unit) to Undead Dreadlord - Sleep (Picked unit)
Wait (1.00) seconds
Pick every unit in (Units of type: Black Night Dummy Unit) and do action: Kill (Picked Unit).

Problem is, it doesn't work. When I cast the ability, no dummy units pop up (I made them visible for the test) and, naturally, no spells are cast. What's going on?

I haven't tested this, but this should work. One peice is in JASS, but this SHOULD get your unit to cast a custom ability. First off, make a new ability based off Dreadlord's Sleep. Now set it's duration on all levels to what you want, cooldown to none, casting time to none, and other things like that. Make a new dummy unit with no shadow, no collision, the abilities Invulnerable and Locust, and make the model file the "Tree of Life Upgrade ability". I needed to convert this to JASS for multi-instanceable reasons, so tell me if it's to confusing:

function Trig_Sleep_Conditions takes nothing returns boolean
    if ( not ( GetSpellAbilityId() == 'AUsl' ) ) then
        return false
    endif
    return true
endfunction

function Trig_Sleep_Func002A takes nothing returns nothing
    call IssueTargetOrderBJ( GetLastCreatedUnit(), "AUsl", GetEnumUnit() )
endfunction

function Trig_Sleep_Actions takes nothing returns nothing
    local unit CASTER
    set CASTER = GetSpellAbilityUnit()
    call CreateNUnitsAtLoc( 1, 'hfoo', GetOwningPlayer(CASTER), GetUnitLoc(CASTER), bj_UNIT_FACING )
    call ForGroupBJ( GetUnitsInRangeOfLocAll(300.00, GetUnitLoc(CASTER)), function Trig_Sleep_Func002A )
endfunction

//===========================================================================
function InitTrig_Sleep takes nothing returns nothing
    set gg_trg_Sleep = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Sleep, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( gg_trg_Sleep, Condition( function Trig_Sleep_Conditions ) )
    call TriggerAddAction( gg_trg_Sleep, function Trig_Sleep_Actions )
endfunction

First create a new trigger, convert it to custom text, remove any lines in the newly converted trigger, and then copy + paste this into that trigger.

There are a few feilds we need to change, since all maps are different. Go into the Object Editor, then hit ctrl + D and look at your custom Sleep ability. Take those first 4 letters and numbers before the ":" and paste them on the part that sais "call IssueTargetOrderBJ( GetLastCreatedUnit(), "AUsl", GetEnumUnit() )", the part I highlighted in bold. Then, go back into the Object Editor, look at your dummy unit, and hit ctrl + D and look at the first four letters and numbers before the ":" and paste that on this part:

"call CreateNUnitsAtLoc( 1, 'hfoo', GetOwningPlayer(CASTER),"

The part being the part I highlighted. THis should work now, and multiple units canc ast it at the same time. I could give you a more complicated way with GUI, but it's better to just use this.

I needed to convert this to JASS for multi-instanceable reasons

Could you elaborate on this some more?
Because? What? ...

To clarify a little, multi-instanceable means so ANY unit can cast the spell at the same exact time, becuase with Global variables, the variable would fight over which unit to pick, and would, for example, maybe allow one unit to cast the ability twice in a row and the other one not cast it all if they were both to cast it at the same trime. So, we use local variables which only exist inside the trigger they were created in. Local variables can be called upon from other triggers, however, but those use Handle variables which I won't get into.

I wrote it in JASS becuase local variables cannot be created in the GUI format, which sucks. I also wrote it in JASS so I could order a dummy unit to cast a custom ability, which usually isn't possible.

You order the unit the order string, or the base ability used to create the dummy ability. It is always possible.

 

[XXXconanXXX]

Yes, but that casts the DEFAULT ability, NOT the CUSTOM. It's MUCH easier, and PLUS I needed to write it in JASS anwyays.

 

[SD_Ryoko]

Yes, but that casts the DEFAULT ability, NOT the CUSTOM.

Mmmm If you make an ability of chain lightning, the order strings don't change.

If your ability is called Nuke The Bastard Dead, you'd order it to

Orc Far Seer - Chain Lightning

There is an example of a spell casting tower in the free trigger code thread.

 

[XXXconanXXX]

Ah, so if I have an ability based off Chain Lightning, and order it to Orc Far Seer - Chain Lightning it will do the Custom ability? Awesome.

@SD_Ryoko: WHat's up with that avatar?

 

[SD_Ryoko]

1. Yessir.

2. Just trying it on. Its from Magic the Gathering.

Very cool! Just 2 minor questions to ask now:
1) If I based this off of Channel, instead of Sleep, would it not sleep the targeted unit?

2) Where can I find a JASS tutorial? I searched the tutorial site, and "JASS" just returned a thing on map protection...

 

[XXXconanXXX]

TEXT ORDER STEING HAS NOTHING TO WITH THE ABILITIES EFFECT, IT'S ONLY USED BY THE GAME.

Sorry for typing in CAPS, but people ask that all the time, and the answer is always no. Plus, in ym first post I said base it off SLeep for the best results. Follow the instructions, and it should work.

JASS tutorial can be located here

Actually, I was wondering if the JASS portion would select the targeted unit: i.e., if I based if off Channel, which has no sleep component, would the trigger sleep the targeted unit anyways. Thanks for the tutorial, wasn't sure quite where it was.

 

[XXXconanXXX]

Channel has an option to select a unit, point, no target, or point and target.

Channel tutorial can be found here

If your new to Channel, it will help alot.
