Gs3

[MysticalDragon]

Its currently enabled on Zone Iphone but not Delteria Iphone. The reason probably is because its half done? It works in NPC Weapons but not classes.

[callimuc]

it is also disabled on Era iPhone

[BlueMelon]

PHP Code:

//#GS3

function onCreated() {
  echo(getAddition(1,2));
}

function getAddition(a:number, b:number):number { 
  var result:number = a + b; 
  return result; 
} 


Works on era, but the class example does not.

[Admins]

We have not enabled it yet on Graal servers. Part of the syntax has already been accepted (but ignored) for a few years.

Guess it's very lenient..i figured it would have kicked up a shitstorm considering you didn't specify a return type for onCreated() (i.e. void)

So how do we go about getting it enabled?

[Skyld]

For what it's worth the V8 NPC-Server prototype that we tested was a much better idea than this.

You should have made it work then >: (

[Gunderak]

Just tested this on Zone, why... It didn't give any error at all.

PHP Code:

  var list:int[];
  list = {1, 2, "Test"}; 


Also curious, why this didn't work.

PHP Code:

//#GS3
class Person extends TStaticVar{
  var nickname:string;
}
function onCreated():void{
  //Create an array of type Person
  var list:Person[];
  //Create some Person objects.
  var me:Person = new Person();
  me.nickname = "Nick";
  var them:Person = new Person();
  them.nickname = "Someone";
  //Add them to the list
  list.add(me);
  list.add(them);
  //Echo each Person element in the list
  for(var someone:Person in list){
    echo("Name: "@someone.nickname);
  }
} 


It does nothing, no errors either.

Also will there be constructors?

Sorry for the spam, but will we be able to extend a TSocket ?

[Admins]

Yes arrays seem to be bugged, we will work on it.

[Twinny]

My desires:

Constructors (being able to overload would also be awesome but perhaps taking it too far)

PHP Code:

class Test {
  var myname : string;
  var myage : int;

  function Test(myname: string) {
    this.myname = myname;
  }
  //Because overloading is fun
  function Test(myname : string, myage : number) {
    this.myname = myname;
    this.myage = myage;
  }

  function echoValues() : void {
    printf("My name is %s and my age is %i", this.myname, (this.myage? this.myage : "Unknown"));
  }
}

function onCreated() : void {
  var TestObj : Test = new Test("Twinny", 25);
  TestObj.echoValues(); 


I know getters/setters will be on the way but this just seems more natural.

I added that printf as it will fail since it's not being referenced in that class(see: extern). For this, perhaps being able to simply prepend global. to global functions would be better. On a similar note, i've not tried but i hope we could use something like super.whatever to access base class items we inherited from :o

I still hate the whole object:type thing. Would love it if it was more like Java and C#, object something;

Hello,

By essence, GScript is a scripting language. GScript is more close to JavaScript-like languages, rather than Java or C#.

This type syntax was chose among other language syntaxes, because it is commonly-used to annotate types in ECMAScript-based languages.

For example:

// ActionScript
function foo(a:int):int {...}

// TypeScript
function foo(a: number): number {...}

// UnityScript
function foo(a : int) : int {...}

// Haxe
function foo(a : Int) : Int {...}

So, when converting from GS2 syntax to GS3 syntax, you just have to add type annotations to the original syntax.

//#GS2
function foo(a) {...}

//#GS3
function foo(a : int) : int {...}

With a Java or C# syntax, this will require more semantic changes to the language, like removing the "function" keyword.
Also, you lose the ability to easily import scripts from similar languages (ActionScript, JavaScript, UnityScript, TypeScript...).

// Java or C#.
int foo(int a) {...}

[Twinny]

Encountered some issues with inheritance,

PHP Code:

//#GS3

class BaseClass {
  var baseclassvar : number = 3;
  
  function overwriteMe() : string {
    return "You shouldn't see me without accessing baseclass";
  }
}

class InheritanceTest extends BaseClass {
  function overwriteMe() : string {
    return "You should see me!";
  }
}

function onCreated() : void {
  //var BaseClassTest : BaseClass = new BaseClass();
  //echo(BaseClassTest.baseclassvar);
  
  var TestObj : InheritanceTest = new InheritanceTest();
  echo(TestObj.baseclassvar);
  echo(TestObj.overwriteMe());
} 


would spit out,

PHP Code:

Weapon/GUI-script Twinny/GS3-Inheritance added/updated by Twinny
Script: Couldn't create object: type BaseClass is not existing in function onCreated in script of Twinny/GS3-Inheritance
Script: Function TestObj.overwriteMe not found in function onCreated in script of Twinny/GS3-Inheritance
0 


Next, uncommenting the lines resulted in,

PHP Code:

Weapon/GUI-script Twinny/GS3-Inheritance added/updated by Twinny
Script: Couldn't create object: type BaseClass is not existing in function onCreated in script of Twinny/GS3-Inheritance

0
bytecode:1305: TypeError: Cannot read property 'name' of null
      typeName = stub.name.extends.name;
                                  ^
Will keep running the old NPC script until server restart. 


I was going to try and do a var BaseTestObj : BaseClass = TestObj; but figured it wouldn't get me too far

[Gunderak]

The class should extend something , try extends TStaticVar.
It will probably make it singleton but eh as long as you only use it once.
But also GS1-3 not being a proper language, it doesn't act like proper languages.
Oddly playing around, if you create the object, the class can extend it o.0 not the actual class though?

PHP Code:

//#GS3
class Foot extends TStaticVar{
  var id:int;
}
class Toe extends Foot{
  var id:int;
}
function onCreated():void{
  var Foot:Foot = new Foot();
  var toe : Toe = new Toe();
  toe.id = 1;
  echo(toe.id);
}

  var toe : Toe = new Toe();
  toe.id = 1;
  echo(toe.id);
} 


And yet,

PHP Code:

class Animal { ... }
class Cat extends Animal { ... }
class Dog extends Animal { ... }
var cat : Cat = new Cat();
var dog : Dog = new Dog();
var cat_as_animal : Animal =  cat as Animal; // OK as the Cat type is a member of the Animal type.
var cat_as_cat : Cat = cat_as_animal as Cat; // OK as the Cat type is a member of the Animal type.
var cat_as_dog : Dog = cat as Dog; // KO as the Cat type is not a member of the Dog type.
var cat_as_animal_as_dog : Dog = cat_as_animal as Dog; // null as the Cat as Animal type is not a member of the Dog type. 


Taken from: http://wiki.graal.net/index.php/Crea...t3#as_operator

It did resolve my query regarding referencing the base class..need to use 'as' operator

[Gunderak]

Ahh nice

[Gos_pira]

What's the point of extending if you still need to use the "as" expression? Seems rather retarded to me.

It would make sense if you used it in a foreach on an array of objects of different type.

Like:

"foreach (djur as Animal in this.Animals)"

while this.Animals contains Dog, Cat, Parrot etc.

I might just be misunderstanding something here, if so, disregard my post.

[Gunderak]

Foreach, I did for(various item:class_type in array)

  for(var someone:Person in list){
    echo("Name: "@someone.nickname);
  }
} 


It does nothing, no errors either.

In the above code, the "list" variable was not initialized. The GS3 compiler currently fails to compile uninitialized variable declarations.

As a workaround, the following code should work:

PHP Code:

//#GS3
class Person extends TStaticVar{
  var nickname:string;
}
function onCreated():void{
  //Create an array of type Person
  var list:Person[] = {}; // Do not forget to initialize.
  //Create some Person objects.
  var me:Person = new Person();
  me.nickname = "Nick";
  var them:Person = new Person();
  them.nickname = "Someone";
  //Add them to the list
  list.add(me);
  list.add(them);
  //Echo each Person element in the list
  for(var someone:Person in list){
    echo("Name: "@someone.nickname);
  }
}

GraalScript3 can be converted to other languages and platforms, we are preparing something interesting for this to show in a few weeks

@Stefan While you're actively reviewing this thread can you elaborate on this and what you're preparing that's interesting?

[Twinny]

Hey Julien/Stefan,

Any update on my class extending problem? http://forums.graalonline.com/forums...9&postcount=90

Also, will overloading functions be supported?

[Julien]

Hello,

GS3 is currently emulating classes using only GS2 features.
While the GS3 syntax already support constructors, getters / setters, inheritance, classes can only be used as containers as for now.

You can only define simple classes with members initialization but functions do not work yet.

Example:

PHP Code:

class Animal extends TStaticVar {
  var name : string;
  var canBreathe : boolean = true;
}

class Dog extends Animal {
  var canBark : boolean = true;
}

function onCreated() : void {
  var dog : Dog = new Dog();
  dog.name = "Woof";
  echo(dog.canBark); // 1 (true)
  echo(dog.canBreathe); // 1 (true)
}

I realize that this deals with Graal's actual source code rather graalscript, but does this means it might possible to port graal to other platforms or handhelds, ie. 3DS and Vita?

[Admins]

We also plan to convert the engine to GS3 sometime We more look into targeting Javascript and C# though

[Gunderak]

Why C#?

[Julien]

There are several cross-platform game libraries that are based on the Mono / .NET Framework (C#):

• Unity 3D (also supports JavaScript-like language)
• Xamarin
• MonoGame
• ...

Conversion from GS3 to C# would allow the Graal engine / tools / scripts to be compatible with these libraries, and possibly deploy on new platforms.

i hope they really go for C# instead of gs3

[Twinny]

C# will also be useful for me (as it's my language of choice atm )

[Jakov_the_Jakovasaur]

hello!

lets just hypothesize for one moment that i were to put my scripting abilities towards developing a playerworld which uses gs3, what alternative platforms could i then expect the playerworld to be made available on, and what time frame could i expect this to be within?

alternatively, if i were to develop a playerworld using gs2 instead, is the current pc platform even going to be supported in future?

thank you!
