Why does this have syntax errors?

[T.s.e]

Hello. I'm tying to make a spell like Luna's Eclipse in DotA. But i've encountered a problem, this syntaxes:
It says ''cannot convert codereturnsboolean to boolexpr.'' and ''constants must be initialized''

scope Eclipse

globals
    private constant integer NumberHit // Maximum number of units hit.
    private constant integer Range //Maximum range.
    private constant integer SpellId //Dummy Spell's ID
    private constant real WaitPeriod //How long to wait between hits
endglobals

function Trig_Eclipse_Actions takes nothing returns nothing
endfunction

function EclipseConditions takes nothing returns boolean
return GetSpellAbilityId() == 'A000'
endfunction

//===========================================================================
function InitTrig_Eclipse takes nothing returns nothing
    set gg_trg_Eclipse = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ(gg_trg_Eclipse, EVENT_UNIT_SPELL_EFFECT)
    call TriggerAddCondition(gg_trg_Eclipse, function EclipseConditions)
    call TriggerAddAction( gg_trg_Eclipse, function Trig_Eclipse_Actions )
endfunction

endscope

Anyone know why?

 

[Trollvottel]

constants must be initialized. so not

private constant integer test

but

private constant integer test = 1

if you want to change it later dont use this constant

 

[phyrex1an]

call TriggerAddCondition(gg_trg_Eclipse, function EclipseConditions)

should be

call TriggerAddCondition(gg_trg_Eclipse, Condition(function EclipseConditions))
