constant local

[Omni]

can you have a constant local? as in

constant local integer i = 0

just wondering, not that it would ever be of any use

 

[Uberplayer]

constant function constant_integer takes nothing returns integer
    return 0
endfunction

function use_constant_integer takes nothing returns nothing
    local integer i = constant_integer()
endfunction

In a way yes..? I just don't see use for this

Yes, constant locals exist. They are called 'globals'.

globals
    constant real fullangle = 360.00
    constant real halfangle = 180.00
    constant real quarterangle = 90.00
endglobals

like thattie .. But then they are no locals, they're globals

    constant local integer i = 1
endfunction

Simply, you can not declare a local variable as a constant. A constant just isn't a variable.
You can assign a variable a value based on a literal constant, meaning a value that does not ever change:

local integer int = 1

1 would be the literal constant in this case, 
1 can never be any other value than 1,
this is what makes it a constant.

Out of curiosity...any point in having constant locals in the first place?
Most likely the only reason why constant globals exist is so that people wouldn't mess with the ones defined in common.j and blizzard.j. The fact JassHelper allows you to define these was definately not something blizzard intended.

There would be no point to them if they did exist, which is why they don't ^_^
