Hard one, may need lua script

[NoobImbaPro]

is there any way when I set a member from a struct to perform an action??

Like I have a

struct asd
    integer i
endstruct

when I do this

set asd.i=5

I want to update my multiboard (my function UpdateMultiboard(player p))

I like to try to avoid a method setI(int value) witch I set the the i and then update multiboard or put a line "call Update..." every time i set the member. I have too many members, that's why. Even operators can't help me as they need a struct first and not an integer.

EDIT: Maybe I was not clear enough. I want to call a method/function when I type this "set asd.i=5"
and then i can call the update. But only for a certain struct like asd

struct myStruct
    integer v
    method operator value takes integer i returns nothing
        set this.v=i
    endmethod
endstruct

function foo takes nothing returns nothing
    local myStruct data=myStruct.create()
    set data.value=15
endfunction

EDIT: huhh, so you can't use operators... nvm
EDIT2: or maybe you can. Only static operators have to use the struct itself, non-static operators (check my example) can use "this"

I know already this, and I try to avoid it. I have to make 25 methods in this way

 

[luorax]

Textmacros are your friend.

//! textmacro New_Operator takes OPERATOR,TYPE,NAME
    method operator $OPERATOR$ takes $TYPE$ i returns nothing
        set $NAME$=i
    endmethod
//! endtextmacro

 

[NoobImbaPro]

Hmm... forgot textmacros, thanks.

EDIT2: or maybe you can. Only static operators have to use the struct itself, non-static operators (check my example) can use "this"

method operator = takes integer i, integer j returns nothing
    set i = j
    call UpdateMultiboard()
endmethod
...
...
...
set asd.i=5

Will this operator run properly? Think a little more...

Even operators can't help me as they need a struct first and not an integer.

You see at the back of "=" is an integer not a struct, that's what I meant


But I think it would be very good for me if someone can do what I want exactly.

Some script that reads code, beginning from set then checks the other letters witch are my struct's name until dot and the other letters until = so the others are the variable and when all conditions are true, we set the value we read after = and call a function

 

[luorax]

That's impossible in (v)JASS.

 

[NoobImbaPro]

It's possible to read the jass code. I want to find a way to read jass code then I can make all of these, but I need someone who knows things about lua

PM Nestharus at Hive or here

 

[Dirac]

static method operator []= takes integer i, integer j returns nothing
set i=j
call UpdateMultiboard()
endmethod

someStruct[x]=y

 

[luorax]

Dirac, that won't work:

Some script that reads code, beginning from set then checks the other letters witch are my struct's name until dot and the other letters until = so the others are the variable and when all conditions are true, we set the value we read after = and call a function

He would like to read the name of the variable from a given string, which is impossible in vJASS. Maybe LUA can do it, but to be honest I know nothing about LUA as I simply don't care how it works.

 

[Nestharus]

code = 
[==[local integer i
local integer b]==]

writejass("scriptname", code)

That would go into an externalblock with //! runtextmacro LUA_FILE_HEADER() at the top and //! i before every line.


You will need to use regex to read vars in your code. I suggest reading up on regex and reading up on the string library in the Lua docs.

By Luorax: but to be honest I know nothing about LUA

Me too.
I think I understood something Nest but I need a bit more advanced explanation

Thank you in advance

Dirac I tried that

static method operator []= takes integer i, integer j returns nothing
set i=j
call UpdateMultiboard()
endmethod

someStruct[x]=y

but this is translated into
local integer i = x
local integer j = y
and then you set x = y

 

[Nestharus]

Me too. I think I understood something Nest but I need a bit more advanced explanation

Thank you in advance

If you want me to teach you Lua, that's not going to happen.

 

[NoobImbaPro]

I don't want you to teach me lua omg.

I have this if I am right based on your previous answer

//! runtextmacro LUA_FILE_HEADER()
//! i code = 
//! i [==[local integer i
//! i local integer b]==]

//! i writejass("scriptname", code)

code = ....
with writejass it writes above code in a line inside the block I want
so what now, what this code does [==[local integer i local integer b]==] ?

http://www.lua.org/manual/5.1/

a = 'alo\n123"'
a = "alo\n123\""
a = '\97lo\10\04923"'
a = [[alo
123"]]
a = [==[
alo
123"]==]

Found in assignments

Also, to give you an idea of what you asked-
[ljass]local string s = "hello world"[/ljass]


Learn Lua manual, then ask your questions.

Grr.... (When dog becomes angry before he barks)

I want when I save map and encounter a

DnD[GetTriggerUnit()].Defense = 5
//or
DnD[GetTriggerUnit()].Defense = DnD[GetTriggerUnit()].Defense + 1

in my code, to add a new line after it writing

call MultiboardUpdate()

is that possible?

I will begin studies at "Informatics - Computer Science" in 1 month, and I don't think this will be the first thing I learn.
So if you want to help me, do what I would like to do, and then from it I will understand and don't ask you again.
Because now these

a = 'alo\n123"'
a = "alo\n123\""
a = '\97lo\10\04923"'
a = [[alo
123"]]
a = [==[
alo
123"]==]

are Chinese for me

I don't know how to begin, how the heck can I do the rest?

 

[luorax]

//! textmacro New_Operator takes OPERATOR,TYPE,NAME
    method operator $OPERATOR$ takes $TYPE$ i returns nothing
        set $NAME$=i
        call MultiboardUpdate()
    endmethod
//! endtextmacro

//! runtextmacro New_Operator("Defense","integer","def")

You have run this textmacro for each variable you may use. If it's too much time for you, you better look for a new hobby.

 

[NoobImbaPro]

I will use that if I won't take what I need for now, I know this option and I already did it.
But I am too curious how it can be done by the way I like.

 

[luorax]

Well, I told you twice that this is the only way to do it, because you can't refer to a variable using its name in the game, and there's no event or anything like that which fires when the value of a variable changes (except the one for reals - but you have to register the event for each variable, so you can't even be lazy there), so this is the only way that exists in vJASS.

But it's your time, go and waste it if that's what you wanna do.

 

[Nestharus]

Well, you can do it in Lua, but that requires knowledge of Lua, and as I said, I'm not teaching you Lua ; P.


Specifically, you want to focus on regex.
