[Trigger] Is attacked event not firing

[Teelo]

I based a spell off Roar... Only so it could apply a self-buff and play a caster animation (otherwise would have used channel... anyway).

• Footman defense
  • Events
    • Unit - A unit owned by Player 6 (Orange) Is attacked
  • Conditions
    • (Unit-type of (Attacked unit)) Equal to Human Footman
  • Actions
    • Unit - Order (Attacked unit) to Night Elf Druid Of The Claw - Roar

Doesn't seem to work. The unit is never ordered to do anything. The function never seems to fire.

Every single attack on my map only does damage via triggers, using the UnitDamageTarget function.

(Uploaded the map, just in case. Saved with NewGen).

I'm not completely sure on this. Do your units actually attack or is it scripted abilities? Because unit is attacked only works if there is an attack.

 

[Teelo]

Its scripted damage.
Except for the buttoned abilities, but the damage is still calculated according to various modifiers, and the damage is then scripted anyway.

Is there something else I can do that will work?

Try damage detection. There's no player event for unit takes damage, but you can work around it. Here's an example which you might find useful.

Example

function FootmenDamagedActions takes nothing returns nothing
    call IssueImmediateOrder(GetTriggerUnit(), "roar")
endfunction

function FootmenDamageDetection takes nothing returns nothing
    call TriggerRegisterUnitEvent(gg_trg_Footmen_Damaged, GetTriggerUnit(), EVENT_UNIT_DAMAGED)
endfunction

function FootmenDamageEnum takes nothing returns nothing
    call TriggerRegisterUnitEvent(gg_trg_Footmen_Damaged, GetEnumUnit(), EVENT_UNIT_DAMAGED)
endfunction

function FootmenOnly takes nothing returns boolean
    return GetUnitTypeId(GetFilterUnit()) == 'hfoo'
endfunction

//===========================================================================
function InitTrig_Footmen_Damaged takes nothing returns nothing
    local trigger AddFootmen = CreateTrigger()
    local region Map = CreateRegion()
    local group Temp = CreateGroup()
    //This is the trigger which triggers when footmen take damage.
    set gg_trg_Footmen_Damaged = CreateTrigger()
    call TriggerAddAction( gg_trg_Footmen_Damaged, function FootmenDamagedActions )
    //Groups all footmen in the map and adds them to the trigger.
    call GroupEnumUnitsInRect(Temp, GetWorldBounds(), Filter(function FootmenOnly))
    call ForGroup(Temp, function FootmenDamageEnum)
    call DestroyGroup(Temp)
    set Temp = null
    //Adds all new footmen to the trigger.
    call RegionAddRect(Map, GetWorldBounds())
    call TriggerRegisterEnterRegion(AddFootmen, Map, Filter(function FootmenOnly))
    call TriggerAddAction(AddFootmen, function FootmenDamageDetection)
endfunction

In your damage_unit_at_location function add in a script that checks unit type. If unittype of unit unit = unit type footmen issue order with no target roar. that simple

Try debugging... add a "game - display test "a"" to the actions.
So you see if the trigger does not fire or if the spell is just not cast.

Yeah thats exactly what I'm going to do. I realised later yesterday that since I have isolated the damage call out as a library, it wouldn't be too hard to put the AI calls in after it too. No need to use a trigger that way.

Thanks.
