Basic Return Help

[Naga'sShadow]

I've got a trigger that wants to cast a spell on all nearby units. I've set the caster function up but the syntax checker says the actions function is expecting a return, except I don't see any actions that give a return.

function Ghostwalk_Slam_Conditions takes nothing returns boolean
    local unit Caster = H2U(GetHandleHandle(Caster, "Caster"))// I added this line and it clears up that error but I'm not sure if its done right
    return ( IsUnitEnemy(GetEnumUnit(), GetOwningPlayer(Caster)) == true )
endfunction

function Ghostwalk_Slam_Actions takes nothing retruns nothing
    call CreateNUnitsAtLoc( 1, 'h001', GetOwningPlayer(Caster), GetUnitLoc(GetEnumUnit()), bj_UNIT_FACING )
    call UnitApplyTimedLifeBJ( 2.00, 'BTLF', GetLastCreatedUnit() )
    call UnitAddAbilityBJ( 'A00O', GetLastCreatedUnit() )
    call IssueTargetOrderBJ( GetLastCreatedUnit(), "banish", GetEnumUnit() )
endfunction

This is the line that calls this function.

call ForGroupBJ( GetUnitsInRangeOfLocMatching(500.00, GetUnitLoc(Caster), Condition(function Ghostwalk_Slam_Conditions)), function Ghostwalk_Slam_Actions )

On a slightly related note "Caster" is a local variable declared earilier in the trigger. I'm using handle variables to move it around. Do I need to refer to it with handles in this part as well?

There is no Caster variable. Or is it defined somewhere else?

you have to, locals are call local because they ARE local

Its probably because 'returns' is spelt wrong.

Simple to make, silly mistake
