[SignIn_SignOut]

Help !!!
My spell Ice Strike attempt to deal damage to unit within 300 range of caster after 0.5sec of cast.
But there is a problem that i cant call ForGroupBJ/ForGroup actions while using timer to wait.

scope IceStrike initializer Init

    globals
        private real damage
        private timer dtimer
        private real period = 0.5
    endglobals

    private function GroupActions takes nothing returns nothing
        // Break point
        call BJDebugMsg("!!") 
        if ( IsUnitDeadBJ(GetEnumUnit()) == FALSE ) then
        if ( IsUnitType(GetEnumUnit(), UNIT_TYPE_MAGIC_IMMUNE) == FALSE) then
        if ( IsUnitType(GetEnumUnit(), UNIT_TYPE_STRUCTURE) == FALSE ) then
        if ( IsUnitAlly(GetEnumUnit(), GetOwningPlayer(GetSpellAbilityUnit())) == FALSE) then
            call UnitDamageTargetBJ( GetSpellAbilityUnit(), GetEnumUnit(), damage, ATTACK_TYPE_MAGIC, DAMAGE_TYPE_MAGIC )
            call AddSpecialEffectTargetUnitBJ( "origin", GetEnumUnit(), "Abilities\\Spells\\Undead\\FrostNova\\FrostNovaTarget.mdl" )
            call DestroyEffectBJ( GetLastCreatedEffectBJ() )
        endif
        endif
        endif
        endif
    endfunction

    private function timeOut takes nothing returns nothing
        local location tempLoc =GetUnitLoc(GetSpellAbilityUnit())
        local group tempGroup =GetUnitsInRangeOfLocAll(300,tempLoc)
        set damage =  ( I2R(GetUnitAbilityLevelSwapped(GetSpellAbilityId(), GetSpellAbilityUnit())) * 50.00 ) + I2R(GetHeroStatBJ(bj_HEROSTAT_INT, GetSpellAbilityUnit(), true))
        call ForGroupBJ( tempGroup, function GroupActions )
        call DestroyGroup(tempGroup)
        call RemoveLocation(tempLoc)
        call DestroyTimer(dtimer)
    endfunction
    
    private function Actions takes nothing returns nothing
        set dtimer = CreateTimer()
        call TimerStart(dtimer, period, false, function timeOut)
    endfunction

    private function Init takes nothing returns nothing
        local trigger t = CreateTrigger(  )
        call RegisterSpellEffectEvent('A00D', function Actions )
        set t = null
    endfunction

endscope

May I know your RegisterSpellEffectEvent use what resources? Just curious.

Edit: I suspect the GetSpellAbilityUnit in tempLoc causes the problem, you should set it as variable in the Actions function and then use the variable in your tempLoc?
