[JASS] Confused about protecting members

[Anachron]

Hey all. Basicly I want to make struct instances of a struct inside another.
Here is the example:

struct Child
    // The members
    unit example
    real x = 0.
    real y = 0.

    public method run takes nothing returns nothing
         call SetUnitX(example, x)
         call SetUnitY(example, y)
    endmethod 
endstruct

struct Parent
    // The members
    real x = 0.
    real y = 0.


    Child array childrens[8191]
    integer index = 0

    public method run takes nothing returns nothing
         local integer i = 0
         
         loop
            exitwhen i > this.index
            call this.childrens[i].run()
            set i = i + 1
         endloop
    endmethod 

endstruct

So, what x and y coordinates are used in the run function of the childrens?
And, what do I need to use the parents member?

So they can be called inside the children?
Protected?

I want to access to the parents value.

Thanks in advance.

struct Child
    // The members
    unit example
    real x = 0.
    real y = 0.
endstruct
 
struct Parent
    // The members
    real x = 0.
    real y = 0.
 
 
    Child array childrens[8191]
    integer index = 0
 
    public method run takes nothing returns nothing
         local integer i = 0
 
         loop
            exitwhen i > this.index
            call SetUnitX(this.childrens[i].example,this.x)
            call SetUnitY(this.childrens[i].example,this.y)
            set i = i + 1
         endloop
    endmethod 
 
endstruct

But you cant make an array of 8191 within a struct, the struct itself has a maximum of 8191, you know,,

Whatever, I fix that problem later.

So I can't accept to a parents member without parameters or extending?
Btw, how it comes that 8191 (128 * 64) are the maximum? Is that the wc3 cache for
a global variable?

 

[Yixx]

I dont know why 8192 (128*64, but 0 is also one) is the maximum array count, is a Jass thing i thought,,

 

[Anachron]

Hmm,... I think blizzard thought that would be enough, and hardcoded it there.. Damnit.

he can have 8191 u he can only have 1 instance of the struct running (i think thou). I think like struct arrays that works like this, lets say we have a array with size 200. So max number of structs will be 8191/200 = 40 instances. Correct me if im wrong

EDIT:

i tried some stuff out and jasshelper have me an error when it was > 12000

You can make your struct have more instances:

struct BigMac[40000] // KINGSIZE


endstruct

Anyways, I dont really know when you actually need all 8000+ instances. Very rarely I would say. ( Spells need usually 12, sometimes more, Projectile systems and knockbacks few hundred ( more would lagg to bad ) )

edit. oh yea, the question.
( Omg , my brain is not working )

What you are looking for is interface. Read JassHelper manual.

 

[Anachron]

Yeah, but I solved it. Thanks all.
I just gave the Parent Instance to the child in a parameter.
