Question about a filter for filtering a group to a specific type

[Technomancer]

Ok so here's the function in question:

function UnitTypeEquals takes unit un, unittype utype returns boolean
    return GetUnitTypeID(un) == utype
endfunction

I copied it and modified it from a dummy GUI script I put together (to get the JASS code) but I need to apply it to a general function that doesn't have a triggering unit. How do I pass what unit I want to compare, or grab that unit from the following function? ( GetUnitsInRectMatchin( ... ) )

Here's the call to the function:

    set g = GetUnitsInRectMatching(GetPlayableMapRect(), Condition(function UnitTypeEquals('h003'))

I have no unit to pass as of the call because they need to be assigned to a group.






So basically what I want to do is select all units of one type and can't figure out how to do it in GUI or JASS (JASS preferred) because I can't figure out how to grab the unit being checked in the checking function.

Is it GetFilterUnit()? If so ummm delete thread plx

Edit:New code, giving me a missing parenthesis error or something...

function UnitTypeEquals takes integer utype returns boolean
    return ( GetUnitTypeId(GetFilterUnit()) == utype )
endfunction

//in a later function
    set g = GetUnitsInRectMatching( GetPlayableMapRect() , Condition( function UnitTypeEquals('h003') ) )

Final Edit: using a better function solves all problems.

I feel like an idiot here, I think I have the syntax right from what I've seen and the debugging I've done in the last 20 minutes.

You cannot use argument intakes in such functions.

Whether create a suitable condition function which takes nothing or use globals to pass the information.

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


globals
- unit UNIT_FILTER
- integer UNIT_TYPE
endglobals

function UnitTypeEquals takes nothing returns boolean
- return GetUnitTypeId(UNIT_FILTER) == UNIT_TYPE
endfunction

And some pseudo code,

...
...
- set UNIT_FILTER = GetFilterUnit()
- set UNIT_TYPE = 'hfoo'
- call GroupEnumUnitsInRect(g, rect, Condition(function UnitTypeEquals))
...
...
