[JASS] Get unit that other comes in range... lol?

[Saishy]

How do I get the unit that is on "": Unit comes within range of "unit"
The unit that comes within range is triggering unit, and the other?

Edit: For my trigger, also works if I find a way to call my trigger setting a variable at start.

function Trig_Sense_Inuyasha_Actions takes nothing returns nothing
    local unit tu = udg_tempunit[0]
    set location tp = GetUnitLoc(GetTriggerUnit())
    set force tf = GetForceOfPlayer(GetOwningPlayer(tu))
    call PingMinimapLocForForce( tf, tp, 1 )
    call DestroyForce(tf)
endfunction

Edit: I got a syntax error at set location tp, someone can help-me?
So, I have other trigger:

• Sense Inuyasha On
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
    • (Unit-type of (Entering unit)) Equal to Half Yõkai
  • Actions
    • Set tempunit[0] = (Entering unit)
    • Trigger - Add to Sense Inuyasha <gen> the event (Unit - A unit comes within 1500.00 of tempunit[0])
    • Trigger - Turn on Sense Inuyasha <gen>

If I could call Sense Inuyasha setting local tu I would solve this.

I don't understand what you mean. You must specify that "unit" parameter yourself.

There is no native function (as far as I know) that is something like "GetUnitThatTheUnitIsInRangeOf()" if that is what you mean.

Sorry, try to specify your problem a bit more.

For example, using vJass

struct UnitData //some generic struct
    trigger dynamicTrig //for this
    //if you need to store anything else about units, you could just make this struct attached to everyone
endstruct

function blah takes nothing returns nothing
    //assuming UnitData exists as the unit's UserData
    //assuming you want to use the triggering unit
    local UnitData dat = GetUnitUserData(GetTriggerUnit())
    set dat.dynamicTrig = CreateTrigger()
    call TriggerRegisterUnitInRange(dat.dynamicTrig,GetTriggerUnit(),<range>,<filter, if any>)
    call TriggerAddCondition(dat.dynamicTrig,Condition(function <actionFunc>))
    //conditions for dynamic triggers are better than actions in several ways, just make sure your action func returns true or false at the end of its body, to prevent desynchs on macs
    //other stuff
endfunction

//somewhere when you want to get rid of it
call DestroyTrigger(dat.dynamicTrigger)

lol I don't even know jass well and you give me vjass?

T.T

I edited first post...
(Lol jass section is really fast)

As for getting that unit, you have to attach it to the trigger.

Gamecache or structs work best.

www.wc3jass.com has some decent tutorials for the former if you're not big on vJass.

As for your syntax errors, you wrote 'set' instead of 'local'.

Uhm, but I think a better way is to call that trigger putting a value on "tu"
This is possible?

something like calltrigger tu = blabla
xD

------------------------------

Edit: Why its so dificult... T.T
I just want to make it: http://www.hiveworkshop.com/forums/showthread.php?t=83932

Could you please rephrase that, Saishy? I'm not sure what you mean.

 

[Saishy]

Well, udg_tempunit is a global that often changes value, so when the gui trigger run the first time the jass one, its correct the local tu takes Inuyasha. but if the jass trigger run again, that will mess the function.

How can I make a way where "tu" will have a fix value?
I thought I could make a way where the gui trigger run the jass trigger putting a value on "tu", so because gui trigger only runs one tim,e "tu" will have a fix value.

 

[PurplePoot]

If the global is constantly changing, wouldn't you want the local to be the same?

Unless you mean it remains constant to a trigger - then you can attach it to the trigger with various systems, the easiest being the Local Handle Variables (Gamecache) I menthoed earlier.

Here is what I wanna to do.

The unit Inuyasha have a sense ability, when someone enter a 1500 range of him, it pinged to the owner of the Inuyasha.

You just say me stuffs that I can't understand. like "Attach the trigger to the unit" "
Can't you just say me how can I do that? I can't believe this will gonna be the hardest skill in my map ¬¬

 

[PurplePoot]

My vJass example is pretty much exactly how you'd do it: I just left out the event and the part where you create the struct, as well as SetUnitUserData(GetTriggerUnit(),dat).

But this don't help if I can't understand what you did. And if I can't edit that...

 

[PurplePoot]

Before you attempt this, then, I suggest you read some basic Jass tutorials, and once you understand it, open the vJass manual (available in the JassHelper folder of JassNewGenPack) and read the relevant content (that about structs).

Ah, I just made a global variable only to store inuyasha.
its not MUI but whatever, this spell is annoying me ¬¬
(Also I don't think I will add a mirror mode, so don't matter don't be MUI)
