Minion Exclusion System

I'm trying to make a summoning spell that does two things:
1. Makes the summoned unit permanent
2. Destroys any other copies of the summoned unit

Here's the code:

JASS:

function Trig_Minion_Summon_Actions takes nothing returns nothing
    local real x = GetUnitX(GetSummonedUnit())
    local real y = GetUnitY(GetSummonedUnit())
    local integer i = GetUnitTypeId(GetSummonedUnit())
    call SetWidgetLife( udg_DemonologistMinion, 0.00)
    call SetWidgetLife(GetSummonedUnit(), 0.00)
    call PolledWait(1.0)
    call CreateUnit(GetOwningPlayer(GetSummonedUnit()),i,x,y,270.0)
    call SetUnitAnimation( GetLastCreatedUnit(), "birth" )
    set udg_DemonologistMinion = GetLastCreatedUnit()
endfunction

The units become permanent (by destroying the summoned unit and creating a new one of the same type), but it won't kill any doubles of the unit (set as the variable udg_DemonologistMinion).

My code is intended to set the permanent unit (the one that is created instead of summoned) as the variable udg_DeomonologistMinion, then destroy it every time. But it's not doing that.

Alevice	Why not just base your spell off of Summon Misha?

Castlemaster	@ Alevice Good point, but I want to make 3 spells on the same hero that work like this, so that wouldn't work out so well. @Need_O2 Yup, that did it. It's not really a system, it's more just a gameplay feature. Thanks for help.

Captain Griffen	Summon Misha, Summon Bear, Summon Feral Spirit. Duration set to zero for second two. Problem solved, I think. EDIT: The problem is that GetLastCreatedUnit doesn't actually work - it doesn't do what it says on the tin. It's a GUI thing. The GUI create unit function sets the last created unit to the variable it returns. So set the unit to a local as you make it.
