#223 Objects

[lipe775]

How about an 'extends' and 'implements' clause in
javascript?

That would allow some very neat features like:

function MyPerson( name ) extends Person
{
this.name = name;
this.hitPoints = 10;
this.onWalk = function( ... ) {}

this.slash = function( enemy ){ enemy.fireEvent(
"onSlash" );
}
var p = new MyPerson( "personName" );
CreatePerson( p, "person.rss", false );

Person p = GetPersonByName( "personName" );
Debug( p.hitPoints );

Person p2 = GetPersonByName( "enemy" );
p.slash( p2 );
===============

===============
function MyTrigger() implements Trigger
{
this.onTouch = function( ... ) {}
this.onClick = function( ... ) {}
this.tile = "";// etc
}
===============
And, when adding triggers, a "reference object" field
should be supported.

I know a some of this can be achieved by using the
prototype clause, but a more close interaction between
the engine functions and the user's objects would
improve Sphere a lot.

Away better than work with strings :D

Not going to happen.
JavaScript supports inheritance already via using prototype

This is more a forum question/request than a bug, please ask
in the forums.

It can _all_ be done by prototyping, actually. Refer to the
official JS guide for details:

Also, Sphere _uses_ the SpiderMonkey JS engine. The
JavaScript syntax is something that's managed in that
project, by those guys: Sphere just uses it.
