AIDS structre question

[W!†A_cRaft]

If i make a structure and make it an AIDS struct like this:

struct random_name extends array
//!   runtextmacro AIDS()
      public integer number
      static method AIDS_filter takes unit u returns boolean
            if (u == udg_myhero)then
                  return true
            endif
            return false
      endmethod
endstruct

Now if i have some other trigger, in which i need to access the data stored in the unit's struct, how do i reference myself to the structure?

I've read in the documentation:

//          - The structs id will be the units index, so getting the struct for
//            a unit inlines to a single native call, and you can typecast between
//            different AIDS structs. This is the premise of AIDS.

but i dont understand how to get the specific structure if i have it's unit?

<struct_name>[whichUnit].member_name

As i remember.

An example:

local unit u = CUS[whichUnit].getLastAttackTarget()
local real dmg = CUS[whichUnit].damage

EDIT: oh, sorry, this doesn't returns the struct itself.

 

[W!†A_cRaft]

okay i do not understand you

take a look at what i did:

    struct Champion extends array
        //! runtextmacro AIDS()
        //========================================================
        //Filter is used to make sure that only hero units owned by players recieve
        //a structure of this type, since units and bossess have static attributes
        private real coefficient
        static method AIDS_filter takes unit u returns boolean
            if (GetPlayerController(GetOwningPlayer(u)) == MAP_CONTROL_USER) and (IsUnitType(u, UNIT_TYPE_HERO))then
                return true
            else
            endif
            return false
        endmethod

now, i have this other function in which i need to set the coeficient field of my struct to a different value:

    private function ondamage_actions takes nothing returns nothing
        local unit u = GetEventDamageSource()
        local real dmg = GetEventDamage()
        local unit target = GetTriggerUnit()
        //now i need to set the coefficient field of a structure Champion
        //created for unit u to a number such as 1.45
    endfunction

Only heroes have this coefficient and it is dynamic so that is why i need to change it. However, i don't know how to do that....

Do i need to do something like:

local Champion hero = Champion[GetUnitId(u)]
set hero.coefficient = 1.45

EDIT: I need the structure returned or placed into a local variable so that i can access the data that is inside of it.

 

[luorax]

it's easy:

private function ondamage_actions takes nothing returns nothing
    local unit u = GetEventDamageSource()
    local real dmg = GetEventDamage()
    local unit target = GetTriggerUnit()
    set Champion[GetUnitId(u)].coefficient = 1.45
endfunction

EDIT: I need the structure returned or placed into a local variable so that i can access the data that is inside of it.

I don't know. I've never used AIDS.

    local real dmg = GetEventDamage()

    set Champion[GetUnitId(u)].coefficient = 1.45
endfunction

the first thing you said is basically already a structure put into a variable, now i just hope it works

 

[Laiev]

struct random_name extends array
//! runtextmacro AIDS()
    public integer number
    static method AIDS_filter takes unit u returns boolean
        return u == udg_myhero
    endmethod

    method getStruct takes nothing returns thistype
        return thistype
    endmethod
endstruct


function test takes nothing returns nothing
    local integer Struct = random_name[Unit].getStruct()
    //if i'm not wrong, it will return some number if the Unit pass to the filter, else will return 0
endfunction

[ljass]return thistype[/ljass]

Is not a correct syntax. It's like saying :

[ljass]return unit[/ljass]
or
[ljass]return real[/ljass].

[ljass]return this[/ljass] would be a correct syntax.

And you should use [ljass]local random_name Struct[/ljass] instead of [ljass]local integer Struct[/ljass]. I actually never tried, but I don't think you can reference struct elements just by using an [ljass]integer[/ljass] variable.

The idea itself is good, though (aka I don't use AIDS so I honestly don't know how it's supposed to be used). Are you sure simply using :

[ljass]local random_name Struct=random_name[Unit][/ljass] doesn't work?...

local random_name Struct < ----- here random name is a variable and Struct is it's name yes?

i'm not creating or referring a struct itself, i'm just getting the value of that method..

Struct = integer if you don't know

I don't think so

 

[luorax]

I looked for the operator in the AIDS struct, and i found this

static method operator[] takes unit whichUnit returns thistype
    return GetUnitId(whichUnit)
endmethod

so i think this will work:

local <struct_name> testvar = <struct_name>[<unit>]

//An example:
function Test takes unit u returns Teststruct
    return Teststruct<u>
endfunction</u>

private function ondamage_actions takes nothing returns nothing
    local unit u = GetEventDamageSource()
    local Champion ch = Champion<u>
    local real dmg = GetEventDamage()
    local unit target = GetTriggerUnit()
    set ch.coefficient = 1.45
endfunction</u>

    local Champion ch = Champion<u>
    local real dmg = GetEventDamage()

endfunction
</u>

Going to try this when i get home

Struct = integer if you don't know

Yes, but can you use that integer as though it was a struct in the vJass code? Will it still compile?

[ljass]local random_name Struct=random_name[Unit][/ljass] doesn't work?...

I don't think so

Why not? I mean, except the fact that the array & struct both have the same name, which shouldn't matter once compiled but could return some syntax error.

//! indent
    local unit u = GetEventDamageSource()
    local Champion ch = Champion

Since when can you use a unit as an array index?

Jass:

He meant to say GetUnitId

 

[luorax]

Since when can you use a unit as an array index?

Since when is equal a custom operator to an array index?

 

[Ashlebede]

Since when is equal a custom operator to an array index?

Custom operator? Where? You don't need a custom operator to set a variable to an array member...

Plain Jass :

[ljass]local integer i = udg_intArray[10][/ljass]

Is correct syntax...

 

[luorax]

I'm not an idiot, i know how do arrays work... but where did you saw arrays? Here's my post, read it once again:

I looked for the operator in the AIDS struct, and i found this

static method operator[] takes unit whichUnit returns thistype
    return GetUnitId(whichUnit)
endmethod

so i think this will work:

local <struct_name> testvar = <struct_name>[<unit>]

//An example:
function Test takes unit u returns Teststruct
    return Teststruct<u>
endfunction</u>

private function ondamage_actions takes nothing returns nothing
    local unit u = GetEventDamageSource()
    local Champion ch = Champion<u>
    local real dmg = GetEventDamage()
    local unit target = GetTriggerUnit()
    set ch.coefficient = 1.45
endfunction</u>

Yes, but can you use that integer as though it was a struct in the vJass code? Will it still compile?

Yes, look at Key Timer 2 by Jesus4Lyf, search for function Add or Get, you'll see (takes integer struct)

Since when can you use a unit as an array index?

Since Vexorian allow it with struct and custom operator

Custom operator? Where? You don't need a custom operator to set a variable to an array member...
