Comprehension of classes

Hi, most of you knew me as a decent scripter, but after 2 years of playing WoW I forgot most of my knowledge of GS2. Something I never did understand was classes and how to utilize them. I know in C++ classes can be used for a multitude of useful things, I'm wondering if the same thing applies with GScript?

For example: Can I call a class(join(X); )

and then later in the script use a string or command set in that class without error? If this currently doesn't exist I think it'd be an awesome idea..

I think of Graal classes as include functions.

Class: bob

PHP Code:


		
			
function bob()

  return "Hi! I'm Bob!";

Weapon: Jane

PHP Code:


		
			
function onCreated()

{

  this.join("bob");

  temp.statement = bob();

  echo(temp.statement);

}

Classes in GScript are probably more closely related to header files in C++ (or object files, even); join is somewhat like #include (or your linker).

Yeah, classes are more like objects in C++, as far as I know.
Classes in Graal are very much like inserting the code of a class into any other script. You can also unjoin (so to speak) classes by using the leave() command. Also, onCreated() in the class is separate from onCreated() in the script you join a class to. onCreated() in a class is called when the class is joined.

Uhm.
No. o_o
When you join something serverside it only uses the serverside portion of the class, and vice versa.

Wrong. It's a good idea to, but when you have a player class, it needs to be joined clientside.

You can't join clientside, then use functions serverside, but it does work vica-versa. I always join serverside, except for player functions.

Classes are a way to make a standard object, or a stand script. For example, for a staff block you might want to make a class so that you can just putnpc2, then join the class, rather then putting in the whole script. And this way, if you need to change something, you can.

Another way to use classes are to provide functions.

Class foo

PHP Code:


		
			
function onCreated()
{
  echo( "moo" );
}

Script in level MYLEVELDONTTOUCH.nw

PHP Code:


		
			
join( "foo" );

Will echo "moo" in RC.

EDIT:
Also you said

That's incorrect. When you join serverside, you get serverside & clientside functions, but when you join clientside you only get clientside functions.

Also wrong. You can join serverside and clientside just fine. And player classes generally ARE joined serverside. o.O

No, clientside classes are supported fully now.

And when joining serverside, you only get the clientside functions if that object has an instance of it clientside, like weapons or npcs in levels. Though players don't appear to work like that, from what little I experimented at least.

Er, yeah my bad. But in clientside, the serverside portion of a class won't work when joined.

Or not? I join classes during the player login event and that's serverside :whatever:

Sorry, I was unclear.

I mean that for a player class with clientside functions, it needs to be joined clientside.

I join my player classes serverside in the control-npc script, but for the clientside functions, you have to join clientside.

Sorry if I was unclear.

You don't for normal classes, but when joining to a player you do. ^^

For other classes, always join serverside.
