Initializer Question

[WarLuvr3393]

I've been using vJass for a while now, and I understand it's use, but I'm just not grasping the concept of using "scope <name> initializer <name>".

What is the point of adding "initializer <name>" to the end of the scope? Please make it in terms I can understand.

Thanks.

Basically the initializer makes the InitTrig of the scope private to the scope it is used in.

So instead of keeping the InitTrig as a public function so it can be passed through the syntax checker, you can make that function private and then use the initializer keyword to make it only useful to that scope.

So:

scope Bleh initializer InitTrig

private function InitTrig takes nothing returns nothing // This can be made private, and only accessible in this scope
    // Stuff here
endfunction

endscope

Basically that was crap.

The keyword name should tell it to you already. The following function is called at map initialization.

scope MyScope initializer Init

    private function Init takes nothing returns nothing
        call BJDebugMsg("Hallo Wurld")
    endfunction

endscope

He was asking what the keyword does, not what an Init function is, im pretty sure that was obvious enough.

It's a function that is called at map initialization.

The KEYWORD initializer, is not a function called at map initialization.

It makes the function that is named after the word initialization run on map init.

scope meh initializer Init // the function within this scope called "Init" will be called at map initialization

I'm sure he could've figured it out... However, thanks for correcting.

scope MyScope1 initializer Init
    function Init takes nothing returns nothing
    endfunction
endscope

scope MyScope2 initializer Init
    function Init takes nothing returns nothing
    endfunction
endscope

"Function redeclared: Init". Proves that initializer will not make the following function private. I don't know where you learned that from.

Meh, sorry. I messed up. I meant to say that it allows(*) an InitTrig to be private.

If you had two InitTrigs, both with the same name, without a public or private keyword, then it would be as uber said, the functions would be redeclared. However, if you use public this would not be the case. The keyword initializer is jut meant to make it easier for the end user, making it more convenient. There is little benefit to using initializers over public init function as far as i know.

At least, this is how it was when i started using vjass, im not quite sure it is the same now, seeing as you can use a private prefix to the function without using initializers now, which i was not aware of. So i would say they are just for convenience if anything else.
