Help me! JAWS are eating me.

[Vinz]

Okay, here is my thread a out v/JASS. I will ask questions endlessly.

Are some BJs that have more than four useful lines applicable for use?
Are libraries available in JASS?
Libraries can be used anywhere right? Just put some funcs?

 

[Malhorne]

Libraries/Scope -> vJAWS.

Some BJs can be used -> TriggerRegisterAnyUnitEventBJ
Basically if you're writing the same thing as the BJ in a func just call the BJ (except the swapped xD)

Libraries are codes that will be put at the top of the map code.
So after you can use the library's stuff everywhere

 

[Vinz]

Oh cool lol. Yeah the swapped part sucks.
So for example,

library NutSkirt Dance
endlibrary

Like that?
You don't call libs right?

 

[chobibo]

library = map header, well almost... I'll leave this to Mal, since I don't remember vjass that well anymore.

 

[Malhorne]

Library is equivalent to the map header you're right.
Like in C :

#include <stdio.h>

Like in Python :

from maths import *

In vJASS :

library Your_Library_Name
    //Put your system's code or some funcs you need everywhere.
endlibrary

 

[Vinz]

So what about those publics and privates?
StructS?
This.var?

 

[Malhorne]

OK I'll try to explain clearly ^^

I - Libraries and scopes
Libraries and scope are the only way (FOR THE MOMENT BUT STICK TO THIS XD) to use private public keywords.
Libraries put your code on the top of the map and can use requires/uses/needs fields to not compile if those other libraries aren't there.
Example : library FearSystem requires Table
This can be optional too : library FearSystem requires optional Table

Scope are the same but can't use the requires fields and aren't put at the top of the map.


II - Private/public
The keyword private means that you will be able to access the thing which is private only in the library/scope it is declare. (IT IS NOT COMPLETELY TRUE BUT STICK TO THIS XD)

The keyword public means that to access it outside the scope/library you need to put the name of the scope/library then put an "_" and at last put the name of the thing.
Example :

library Test
    globals
        public constant integer A = 1
    endglobal
endlibrary

//LATER IN ANOTHER SCOPE

scope Test2
    globals
        constant integer B = Test_A
    endglobals
endscope

III - Struct
It is OOP language -> Object Orientation Programming (IIRC).
Meaning that you can create your own variable type, you want to create another location which is not buggy ?

(private/public) struct Location
    real x
    real y
endstruct

function Test takes nothing returns nothing
    local Location loc = Location.create() //That creates an instance of your struct
    set loc.x = 42 //That allows you to change the x value of your struct instance.
    set loc.y = 1764 //That allows you to change the y value of your struct instance.
    //Do your stuff
    call loc.destroy() //Never forget to destroy them
    //No need to null this it is counted as integer.
endfunction

 

[chobibo]

location has bugs? IIRC, it's just slower than using real values, which are just numerical values, whilst locations are objects which have overhead when being created.

I'd still use coordinates though, the overhead ain't worth it. Unless of course you're doing maths haha xD

 

[Malhorne]

Not bugs yes you're right but slower and they leak ^^
I miss-said again :/

 

[Vinz]

Thanks..

 

[chobibo]

Use scopes for spells, use libraries for systems.

 

[Malhorne]

Yes I do like this most of the time.

 

[chobibo]

That was just a random tip lol, just like tips on loading screens from games haha xD

 

[Vinz]

So I wanted to port a spell into vJASS, what's this scope thing? Are they like libraries?

Is a scope any different from libraries?

 

[chobibo]

That's a very vague question, add details plox.

 

[Malhorne]

As I said libraries put the code at the top of the map.

Scope is just data xD
If you don't need any requires fields and if you don't need to put the code at the top of the map use scope.

Scope for spells is the basic rule if you don't know what to do.

 

[Vinz]

Would having long-as-hell lines crash WE in JNGP?

 

[Malhorne]

Not at all.
If you have more than around 6-7k lines in one trigger it can be laggy that's all.

Ah you mean long line xD !
Sorry.
But no bug too.

Little trick for multiple conditions :

if GetUnitAbilityLevel(u, ID)>0 and/*
    */...../*
    */..... then

 

[Vinz]

You can use multiple lines? :O
And why don't my globals 'declare' in libraries?

 

[Vinz]

Anyways 'cannot convert real to player'

call CreateUnit(12, GetUnitTypeId(GetEnumUnit()), GetRandomReal(GetRectMinX(udg_NC_Rect[r]), GetRectMaxX(udg_NC_Rect[r])), GetRandomReal(GetRectMinY(udg_NC_Rect[r]), GetRectMaxY(udg_NC_Rect[r])), GetRandomReal(0.00, 360.00))

 

[Malhorne]

Player(12) instead of 12.

 

[Vinz]

Thanks.

 

[chobibo]

How did you declare the globals?

 

[Vinz]

globals
real array NC_Time
endglobals

 

[chobibo]

Looks valid to me, what was the error?

 

[Malhorne]

Put the code in JASS tags.

globals
    real array NC_Time //Will work everywhere
    private real array NC_Time //Will work only on scope/library
    public real array NC_Time //Will work only on scope/library
endglobals

 

[Vinz]

'Undeclared'
Anyways this bugs, saying unexpected 'TempReals':

call DestroyEffect(AddSpecialEffect("Objects\\Spawnmodels\\Other\\NeutralBuildingExplosion\\NeutralBuildingExplosion.mdl", udg_TempReals[0], udg TempReals[1] ))

 

[Malhorne]

Ha !!
You don't have to put udg anymore by using globals.

 

[Vinz]

Umm.. why?

 

[Malhorne]

Because it is a feature
When using globals blocks you get rid of udg (for your finger's sakes)

 

[chobibo]

Yeah haha xD! Worship da Almighty Malhorne!

EDIT: It's because the stupid World Editor appends udg (user-defined global) to the global identifier. One of Blizzard's weirdness...

 

[Malhorne]

Thanks :3 !

 

[Vinz]

Sadly in that trigger I don't. Anyways what could be causing that?

 

[Malhorne]

What the oO ?
So did you declare your vars in the variable editor (I suggest to use only globals blocks from the moment you get JNGP) ?

 

[chobibo]

@udg TempReals[1]@

You forgot something
What could that be?

 

[Vinz]

Yes, because last time it threw an error saying the vars were undeclared. Which drove me away.

E: Oh wait, no 'udg_' right?

 

[Malhorne]

Ahah I didn't see this xD !

Hail to chobibro

 

[chobibo]

not the entire udg_, just the _ haha xD

 

[Vinz]

Okay. Ty.

 

[chobibo]

You seem a bit sad Wrathion? What bothers you broda bear?

 

[Vinz]

Nothing, I just wanted to add some variation. Another 'thanks' would be weird to me. :O

 

[chobibo]

c001, v4r14t10n2 4r3 h4wt!

 

[Malhorne]

Trad : Cool, variations are hot !

See ya guys I'm going to sleep !

 

[chobibo]

2l33p 12 4 duh w34k! d0n't 2l33p!

 

[Malhorne]

Trad : Sleep is for weak ! Don't sleep !

I sleep a bit even if I don't need 8h I need at least 5-6h

 

[Vinz]

I need 10hrs </3

 

[Malhorne]

Ahah xD

 

[chobibo]

I sleep 4 times per week 6-7 hours on average. I'm gonna die early, so says medical research.

 

[Paliouras]

8hrs every day doesn't matter if it is Saturday/Sunday.
Oh look another offtopic!

 

[Malhorne]

Some people don't need that much to sleep.
@chobibo : i happened to me to sleep 4h per week and no problem (I'm kinda insumniac and sometimes I can't sleep at all :/)
