JASS: Returning an Integer

[SkeletonKings]

function notreallyafunction takes nothing returns integer
return udg_IntegerVariable
endfunction

Ooh, look, now when you call that function, it gives you the variable IntegerVariable.

What I don't understand about this is when he says "it gives you the variable IntegerVariable"

What use could returning an integer have if it's global? Can someone give an example of this?

 

[Need_O2]

its like
set OMFGSOMETHING = notreallyafunction()
and OMFGSOMETHING becomes what notreallyafunction gives and it gives the value of IntegerVariable

Remember how in GUI you say something like:

• Set AUnitVar = (triggering unit)

In jass this would be something like:

local unit AUnitVar
set AUnitVar = GetTriggerUnit()

GetTriggerUnit takes nothing returns unit

in other words, it'll return a unit which can be assigned to a variable. Your own functions can also return variables you've used in your function.
