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
This.

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:

HTML Code:
// 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.

HTML Code:
//#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...).

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

Encountered some issues with inheritance,

Graal Script 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,

Graal Script Code:
Weapon/GUI-script Twinny/GS3-Inheritance added/updated by Twinny
Script
Couldnt create objecttype 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

Next, uncommenting the lines resulted in,

Graal Script 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
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

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?
Graal Script 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);

And yet,

Graal Script 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

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.

for(var someone:Person in list){
    echo(

  }

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:
Graal Script 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?
