[vJASS] Refactoring from GTrigger to RegisterPlayerUnitEvent

[odemmah]

I have an old spell which uses very old and obsolete libraries. I wanted to upgrade them with their better and up-to-date counterparts.

Converting this part;

         private static method onInit takes nothing returns nothing
             call GT_AddStartsEffectAction(function thistype.Action,RAWCODE)
             call GT_AddBeginsCastingAction(function thistype.Action2,RAWCODE)

           set thistype.cf = Condition(function thistype.DoDamage)
        endmethod

to this part;

         private static method onInit takes nothing returns nothing
            call RegisterPlayerUnitEvent(EVENT_PLAYER_UNIT_SPELL_EFFECT, function thistype.Action)
            call RegisterPlayerUnitEvent(EVENT_PLAYER_UNIT_SPELL_CAST, function thistype.Action2)
           
            set thistype.cf = Condition(function thistype.DoDamage)
        endmethod

This causes weird event firing behaviors and the worst is all spells now trigger this custom spell as well.

I'm just started learning this stuff, helps are appreciated.
