[vJASS] Making TimerUtils optional?

[Geshishouhu]

Hi all. If I make TimerUtils optional, what should I put after "static if"? The function name in the TimerUtils library? Such as

static if LIBRARY_NewTimer then
     call NewTimer(......)
else
     call TimerStart(.....)
endif

Thanks.

For TimerUtils you do: static if LIBRARY_TimerUtils then.

Edit:

static ifs are like normal ifs, except that the condition must contain only constant booleans, the and operator and the not operator.

Note the following doesn't work for TimerUtils, because it doesn't use structs at all.

In general you can also do: static if struct.method.exists then for instance static if DummyCaster.castTarget.exists then

or when implementing modules (here Alloc) you can do stuff like static if thistype.allocate.exists then

Lately I've been using this for my uploaded spells:

        private static method onInit takes nothing returns nothing
            static if LIBRARY_SpellEffectEvent then
                call RegisterSpellEffectEvent(AID, function thistype.run)
            else
                local trigger t = CreateTrigger()
                call TriggerRegisterAnyUnitEventBJ(t, EVENT_PLAYER_UNIT_SPELL_EFFECT)
                call TriggerAddCondition(t, Condition(function thistype.check))
                set t = null
            endif
            
            static if not LIBRARY_DummyCaster then
                static if LIBRARY_UnitIndexer then
                    set UnitIndexer.enabled = false
                    set c = CreateUnit(NEUTRAL,DUMMY_CASTER,0,0,0)
                    set UnitIndexer.enabled = true
                else
                    set c = CreateUnit(NEUTRAL,DUMMY_CASTER,0,0,0)
                endif
                call SetUnitPosition(c,2147483647,2147483647)
                call UnitAddAbility(c, BUFF_CAST_ID)
            endif
        endmethod

or here is a small piece out of my Blizzard Alternative

    private struct Needle extends array
        implement optional Alloc
        /*
        *   x and y are requires to determine the impact location.
        *   t keeps track of the falling time.
        */
        real x
        real y
        real t
       
        static if (not thistype.allocate.exists) then
            static integer array rn
            static integer ic = 0
        endif
       
        static method create takes real x, real y, real field, real angle returns thistype
            static if (thistype.allocate.exists) then
                local thistype this = allocate()
            else
                local thistype this = rn[0]
                if this == 0 then
                    set ic = ic + 1
                    set this = ic
                else
                    set rn[0] = rn[this]
                endif
            endif

You're welcome , btw the allocation in Alloc is done different then mine. It only uses one integer array and nothing else.

Thanks a lot, BPower!! Nice example!
+Rep if I can!
