Looking for "Teacher"

[ChaosKnight]

Im kinda new to vJASS. I wanted to learn how to use methods and/or structs.
So i wanted someone that could pm question to.
Anyone willing to?

PS: Im aware of that this post may be can be a little childish. But im serious.

Maybe you should tell people if you know Jass or not and how good you are in Jass I think you should read some tutorials and try a bit yourself and if you have questions you can pm me

you can pm me. i don't know much, but i might be able to answer some questions. i have been using structs and methods with success, even though i don't fully understand them.

i know that sounds funny, but what i mean is that i wouldn't know how to make up my own struct and method combination, but i've been copying the same sets and editing them as necessary. i can show you some examples if you want, but first i guess we gotta figure out what your questions are.

Why don't you just post your question here. Someone will help you.

 

[PurplePoot]

I'd be happy to help as long as your questions are relatively short (I'm happy to read a page or two of code, but I don't want to debug systems).

Why don't you just post your question here. Someone will help you.

Here:

I will use an Thehelper system, called UAC - Unit Aura Control.
It wants methods to be activated. I want units to loose strenght the closer they come to the owner of the aura.

UAC - Unit Aura Control.

I can help you with that but I've never used UAC; I'd prefer to make something like that from scratch.
Basically you're going to enumerate units around the owner of the aura, check the distance between their origins, and reduce strength for the enumerated unit per some math function.

Yeah, in the theory, it's very easy. But for me which does know a little, i dont even know how to enumrate in range.

Well when you enumerate units it uses a group to enumerate them to.

function ForGroupFunc takes nothing returns nothing
    local unit picked=GetEnumUnit() //each enumerated unit will be passed through this function
    //say we wanted to add strength to enumerated units, only if they are heroes
    if(IsUnitType(picked, UNIT_TYPE_HERO)) then
        call SetHeroStr(picked, GetHeroStr(picked)+5)
    endif

    //remember that before the function ends the handle variable must be set to null
    set picked=null
endfunction

function EnumerateUnits takes nothing returns nothing
    local group g=CreateGroup()
    local real x=0 //this is the x-coordinate of the "in-range" point
    local real y=0 //this is the y-coordinate of the "in-range" point
    local real r=100 //this is the range that enumerates are enumerated from point x, y

    call GroupEnumUnitsInRange(g, x, y, r, null) //the null is a filter function that can filter out units
    //now that you have enumerated the units with the function, you can direct actions
    //towards those units by using ForGroup, such as:
    call ForGroup(g, function ForGroupFunc)
    //the ForGroupFunc is defined above, and each enumerated unit is referenced as GetEnumUnit()

    //because a group is a handle, it must be destroyed/nulled
    call DestroyGroup(g)
    set g=null
endfunction

JASS works in functions. Everything that "happens" in JASS is because of actions that are defined in functions.

AWSOME! But, could you add that when a unit comes 100 It gains 5 str, 75 range +10 str and at last 50 range and + 15 str? And i want them to just be affected when they are allies of the owner of the aura.

+rep if you do so. !

Delicious.

 

[ChaosKnight]

Bumpety Dump.

 

[Berb]

What are you bumping for? Do you have another question...? The last thing you said was "Delicious".

 

[ChaosKnight]

I bumped, because i wanted to know, how to use this in UAC. Missed that?

 

[Berb]

Oh, I'm unfamiliar with UAC.

 

[swipe5weep]

ChaosKnight on the link you provided, the steps on how to use UAC was stated there.

 

[ChaosKnight]

Yeah, that was maybe i asked for it..
