Something wrong

Hello, i converted the melee initialisation Gui trigger in custom script and when i check for sintax errors it shows me this

Line 14: Undeclared variable gg_trg_Melee_Initialization

function Trig_Melee_Initialization_Actions takes nothing returns nothing
    call MeleeStartingVisibility(  )
    call MeleeStartingHeroLimit(  )
    call MeleeGrantHeroItems(  )
    call MeleeStartingResources(  )
    call MeleeClearExcessUnits(  )
    call MeleeStartingUnits(  )
    call MeleeStartingAI(  )
    call MeleeInitVictoryDefeat(  )
endfunction

//===========================================================================
function InitTrig_Melee_Initialization takes nothing returns nothing
    [B]set gg_trg_Melee_Initialization = CreateTrigger(  )[/B]
    call TriggerAddAction( gg_trg_Melee_Initialization, function Trig_Melee_Initialization_Actions )
endfunction

Can you pls enlighten me <3

 

[emjlr3]

what is the name of your trigger divider?

 

[LuckyStrike]

srry, but i have no ideea what that is...i just tried to convert the default melee initialisation trigger from anny map in Jass script and when I clicked sintax check ( to check for errors) it displayed this :

Line 14: Undeclared variable gg_trg_Melee_Initialization

function Trig_Melee_Initialization_Actions takes nothing returns nothing
    call MeleeStartingHeroLimit(  )
    call MeleeStartingAI(  )
    call MeleeInitVictoryDefeat(  )
endfunction

//===========================================================================
function InitTrig_Melee_Initialization takes nothing returns nothing
    set gg_trg_Melee_Initialization = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Melee_Initialization, function Trig_Melee_Initialization_Actions )
endfunction

I just started today to learn about Jass, so pls have patience with me. Thx .

Don't worry about that error.
Syntax Check will almost always give errors.
As long as you can save your map (CTRL + S) without errors, you're good.

Thanks for the advice:thup:. That means that anny good working GUI trigger can be converted into Jass and properly work?

 

[WolfieeifloW]

Any GUI trigger that works can be converted to working JASS.

Notice how working is bolded.
There's a huge difference between working and efficient !

 

[LuckyStrike]

So what to you really mean : the same script as in GUI is more efficient in Jass ?

 

[WolfieeifloW]

No.
I mean when you convert a trigger from GUI to JASS, it's still as inefficient as it was in GUI.
You need to "optimize" your script to make it efficient.

Oh...then i've got an "optimization" problem, because I can create my own script, without understanding which parameter does what...Its just as in chinese to me... :banghead:Btw is there anny tutorial about Jass, explaining more concrete?

 

[WolfieeifloW]

These are the two tutorials I used to learn:
One
Two
Read them in order.

you converted the default melee initialization trigger to JASS... and then renamed the trigger. If you want to rename a trigger, you either have to make a scope with an initializer, and create a local trigger (vJASS syntax), or you have to change the name of the Initialization function and trigger name to match the new name of the trigger. You can see what I mean in these lines:

function InitTrig_Melee_Initialization takes nothing returns nothing
    set gg_trg_Melee_Initialization = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Melee_Initialization, function Trig_Melee_Initialization_Actions )
endfunction

change into this:

function InitTrig_TRIGGER_NAME_GOES_HERE takes nothing returns nothing
    set gg_trg_TRIGGER_NAME_GOES_HERE = CreateTrigger(  )
    call TriggerAddAction( gg_trg_TRIGGER_NAME_GOES_HERE, function Trig_Melee_Initialization_Actions )
endfunction

Don't worry about that error.
Syntax Check will almost always give errors.
As long as you can save your map (CTRL + S) without errors, you're good.

I believe the Syntax Check only gives errors for vJASS (with a few possible exceptions with warnings). In this case, however, it is on regular JASS, which did have errors in the first place.

However, WolfieNoCT is correct in that you should use the save button to check for errors, and not the Syntax Check button, as the Syntax Check button does not recognize vJASS syntax.

 

[WolfieeifloW]

He didn't change the name actually .
Open your NewGen, make a new map, and convert it.
It gives the error he posted .

 

[LuckyStrike]

Thank you very much guys, helped me alot!:thup:

 

[simonake]

Whats the difference between globals and locals?

 

[Romek]

Globals can be used everywhere and anywhere. They can be set from any function, and then used in another.
Locals are function-specific. They cannot be used by other functions, but they keep things MUI.
All GUI variables are globals.

Maaaybe I'm just to stupid buuuut arn't there two " , " missing at your last Trigger you posted

here:

call AddSpecialEffectLocBJ( l[COLOR="Red"],[/COLOR] "Abilities\\Spells\\Human\\ThunderClap\\ThunderClapCaster.mdl" )

and here:

call UnitDamagePointLoc( u[COLOR="Red"],[/COLOR] 0, 500, l, 100, ATTACK_TYPE_NORMAL, DAMAGE_TYPE_NORMAL )

It might just happend that I'm to silly aswell, but I copyed to WE and it threw up Errors without them...

~Sorry if somebody already mentioned, I just noticed that it's still without~

 

[WolfieeifloW]

He might've/probably just forgot them .
If adding them in fixed it, then go for it!

EDIT: Doesn't damaging a point desync Mac users?

 

[IAmSoDoomed]

thanks, I just wondered if it had any reason for not having them

 

[Vozho]

A problem comes out...

Well,this tutorial is nice,thanks for trying to learn jass some people who don't know anything about it,for e.g. me but it is incomplete...

i have some problem.It looks like jass is making an error.When is try to convert GUI trigger from one of my maps:

events:
Time - Every 30.00 seconds of game time
Conditions
Actions
Quest - Display to (All players) the Hint message: |c0080FFFF(If you w...

it converts to:

function Trig_message_1_Actions takes nothing returns nothing
    call QuestMessageBJ( GetPlayersAll(), bj_QUESTMESSAGE_ALWAYSHINT, "TRIGSTR_076" )
endfunction

//===========================================================================
function InitTrig_message_1 takes nothing returns nothing
    set gg_trg_message_1 = CreateTrigger(  )
    call TriggerRegisterTimerEventPeriodic( gg_trg_message_1, 30.00 )
    call TriggerAddAction( gg_trg_message_1, function Trig_message_1_Actions )
endfunction

The problem is:There is no text of my quest message anywhere in jass script!
what happened?Can this be solved?
(In GUI trigger only a beginning of the text is displayed...)
