Don't put them in the same moviescript, put them in two
separate moviescripts. If they are in the same script, it
creates a circular dependancy.

Thank's
But yesterday director hangs all the time cuz of the:
function holyday ()
{
}
function xmas ()
{
}
xmas.prototype = new holyday ();
When i remove the last line director works fine (these 2
objects are in a
single moviescript).
And "A Zavatone" it's right... it's not
"herency" it's "inheritance" i
guess... im not a programmer, and in my country this
programming resource is
called "herencia".
Well, good luck,
And thank you!

actually, its
function myNewClass() {
...
}
myNewClass.prototype = new BaseClass();
The "trick" that differs from regular ECMAScript
1.4 is that Director
compiles its scripts IN ORDER from first to last in a given
cast, and IN
ORDER from first cast to last cast. Your BaseClass script
MUST appear
BEFORE your myNewClass script - otherwise the setting of the
prototype will
barf because it doesn't yet have bytecode for how to
construct a new
BaseClass.
Also, if you change the BaseClass in any way, you will need
to recompile not
only the BaseClass, but also the myNewClass, because the
reference that the
prototype of your new class holds could still be an old (and
now
invalidated) BaseClass object.
Moral of this story - compile the base class first, then
compile the new
class, then run. Works like a charm.

Danny,

Sure, but it's Javascript syntax in director not in lingo.

In ecmascript (as far as i know) herency work in that way,
setting the
prototype of an function (CLASS) to the base class.
In c++ would be:
class cclass: public cbaseclass
In javascript it's:
function cclass ()
...
cclass.prototype = new cbaseclass ();
All the functions and variables from cbaseclass are
"copied" or "instanced"
into cclass.
I put "CSprite" and "CClipper" and the
first "C" means "class" later in the
code i'll use something like this:
var dummyvar = new CSprite ();
> And CClipper () is just the value 0 anyway, so 'new
CClipper()' is the
> same as 'new 0' which doesn't make any sense.
Why is 0? I don't understand that. You mean
"null"?
CClipper it's an object, class... when i put "new"
that means a new instance
of CClipper.
Whatever, i don't know if this's it:
class.prototype = new baseclass ();
or:
class.prototype = new baseclass;
or:
class.prototype = baseclass ();
Hum, nevermind, i think the shockwave plugin isn't good for
me. =(
I wanna cry.
