Calling functions between triggers?

[Nevyll]

Hai, I'm working on a hero picking system, but I've come across a problem; whenever I try to call a function between 2 triggers, it gives me a "Expected Function Name" error :banghead:

I put the function "StartPick" in a trigger above the Start Pick trigger:

function StartPick takes nothing returns nothing
endfunction

function InitTrig_Pick_Hero_Functions takes nothing returns nothing
endfunction

And when I try to call the StartPick function, it gives me errors

function Trig_Start_Pick_Actions takes nothing returns nothing
    call StartPick()
endfunction

function InitTrig_Start_Pick takes nothing returns nothing
    set gg_trg_Start_Pick = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Start_Pick, function Trig_Start_Pick_Actions )
endfunction

Thanks in advance!

You can't refer to functions between triggers, at least not in the manner you're trying.

With the unmodified World Editor, you can put functions in the map header (click the map name in the Trigger Editor), and then they can be called from any other trigger.

If you're using the Jass NewGen Pack (Windows only), you can put your functions in a library or something like that, and I think it'll let you call them between triggers.

As a last resort, you can use [ljass]ExecuteFunc("NameOfYourFunction")[/ljass], but this has the risk of crashing your map if the function in question does not exist, does not allow you to pass parameters, and sometimes is corrupted if you intend to optimize your map before release (because it changes function names and may not find this reference).

Ah, yeah, I've heard of the ExecuteFunc() and the Map Header option, but I'm trying to avoid those

The reason I want to have it this way is because of readability and such, and I've seen in maps like the Azeroth Grand Prix and the Dota 6.32 Open Objects that Blizzard and IceFrog respectively(?) uses some triggers as collection of functions; the "core" trigger on DotA for example.

I was looking for the exact same thing.
I guess putting the functions in the header makes the functions global.
But I want to know how you can export and import functions.
I don't want my million lines of function code all jammed into my header.
Can someone answer???

You can't call functions between trigger slots in World Editor? Wow, I've forgotten how insanely bad its syntax checker was. JassHelper utterly destroys the old limitations of JASS.

You can, unreliably. The order at which GUI "Triggers" appear in your final map script is completely different to the order they are listed in the Trigger Editor. Something to do with order of creation I think. Anyway, you might get lucky once, then you might save your map again and it won't work because the order has changed. The map header is there for a reason. If you don't like it then you had better get Newgen.

You can declare the function in the map stuff thing and with
function Sleep takes (whatever) return (whatever)
endfunction
then you can create a function in the trigger u want that does what u want. u will have the function in the map section but it will be in the trigger u want to. I have made a map with it but dont know how to upload.

Great!

Well if it's the only possible way I guess I"ll stick with that.

found it

And Thank you for telling me how to predeclare a function.
I was actually looking for that too. Very nice Very nice

Thank you everyone!!

Of course, if you want, you can use libraries if you use JassHelper.
