Referencing preplaced units/items in JASS

[Tsaras]

How do I go about referencing preplaced units in JASS code?

I know that when using a preplaced unit/item in a GUI trigger, WE automatically creates a gg_ variable for it, which can be used to reference this unit. But what if there are no GUI triggers? The only place where this unit can be set to a variable is when it is created:

set u = CreateUnit(p , 'U007' , - 1708.6 , - 1267.4 , 277.550)

And since this code is generated and overwritten by WE every time the map saves, it cannot be used to store this into another variable!?

You can place an unit, create some trigger and convert it in JASS to see for yourself

call RemoveUnit( gg_unit_hfoo_0000 )

^ There's no more GUI in there but the reference is still available

Is this the designated method to reference preplaced units? Create trigger just to get the variable in there?

Yes. Standard World Editor development is pretty dated, but you can always upgrade:

I guess you can skip the trigger creation if you know the unit's raw code and its number among all of the units that you've placed but that gives me a headache just thinking about it lol

In this case what I do is just creating a trigger that I will never use that references that unit.
