My First Jass System... Help

[Romek]

Since I'm trying to learn JASS, i decided to try and make a very, very simple system to help me learn.

But I get a lot of errors...

function Makebig takes trackable A, returns nothing
    if
      A == trackable[1]
      then
      SetUnitScale(unit[1],1.50,1.50,1.50)
      else
      SetUnitScale(unit[2],1.50,1.50,1.50)
      endif
endfunction

function InitTrig_HeroSelection takes nothing returns nothing
    set trackable[1] = CreateTrackable ("", 100.00,100.00,0.00)
    set trackable[2] = CreateTrackable ("", 200.00,100.00,0.00)
    set unit[1] = CreateUnit (12,hkni,100.00,100.00,90.00)
    set unit[2] = CreateUnit (12,hrif,200.00,100.00,90.00)
    set gg_trg_hover = CreateTrigger()
    call TriggerRegisterTrackableTrackEvent(gg_trg_hover, trackable[1])
    call TriggerRegisterTrackableTrackEvent(gg_trg_hover, trackable[2])
    call TriggerAddAction(gg_trg_hover, function Makebig(GetTriggeringTrackable())
endfunction

What have i done wrong?
I'm rubbish at JASS, please remember this when commenting.

Edit: I just realized i didn't have my variables
I made unit. How do I make Trackable or Handle Variables? (Globals)

Edit Again: Maybe i should try simpler things first

global variables must have a udg_ prefix or you have to use a local variable like:
local trackable array t
set t[1] = CreateTrackable()

Unit rawcodes should have '' around them.

You can't pass variables like this:
call TriggerAddAction(gg_trg_hover, function Makebig(GetTriggeringTrackable())
GetTriggeringTrackable() already exists in the called function.

Forgot about the prefix
I don't want to use a local trackable.
I want to know how to make a global one (Handle or the likes) (if its possible)

What should I do instead for

call TriggerAddAction(gg_trg_hover, function Makebig(GetTriggeringTrackable())

?

I don't think there are such things as global trackables

But you can try looking for it in Variables

 

[ReVolver]

I don't think there is a way to make global trackables, I think they only work for 1 player.

 

[Technomancer]

You can't just declare it in globals tags? (vJass)

globals
trackable array t
englobals

I don't think there is a way to make global trackables, I think they only work for 1 player.

Trackables work for all players, but there is no way to figure out what player that triggered the trackable event so you usually create one trackable per player and attach the player to the trackable or to the trigger.

I was thinking that, but i wanted someone to post it... so i know its right

 

[Technomancer]

I don't know what a trackable is, but I'm sure you can make it into a global array.

 

[Hero]

Lets check the all the .j files that blizzard has in JASSCraft we are bound to find something there?

Or We should....is it in the variable table where you make new variables and set them to Unit,Player, etc?

You can always do this:

function Makebig takes trackable A, returns nothing
    if A == trackable[1] then
        call SetUnitScale(unit[1],1.50,1.50,1.50)
    else
        call SetUnitScale(unit[2],1.50,1.50,1.50)
    endif
endfunction

function Actions takes nothing returns nothing
    call MakeBig(GetTriggeringTrackable())
endfunction

function InitTrig_HeroSelection takes nothing returns nothing
    set trackable[1] = CreateTrackable ("", 100.00,100.00,0.00)
    set trackable[2] = CreateTrackable ("", 200.00,100.00,0.00)
    set unit[1] = CreateUnit (12,'hkni',100.00,100.00,90.00)
    set unit[2] = CreateUnit (12,'hrif',200.00,100.00,90.00)
    set gg_trg_hover = CreateTrigger()
    call TriggerRegisterTrackableTrackEvent(gg_trg_hover, trackable[1])
    call TriggerRegisterTrackableTrackEvent(gg_trg_hover, trackable[2])
    call TriggerAddAction(gg_trg_hover, function Actions)
endfunction

Then put the rest of the actions in the "Actions" function.

In code parameters, you can have nothing but "function FUNCNAME".



Yes, you can create global trackables. You can create a global for any variable type.
