Hello :)
try this code :
class Component extends MovieClip
{
// constructor
function Component()
{
}
///////////// Init AsBroadcaster
static private var _INIT_BROADCASTER_ =
_global.AsBroadcaster.initialize( Component.prototype ) ;
public var addListener:Function ;
public var broadcastMessage:Function ;
public var removeListener:Function ;
/////////////
public function onPress():Void
{
// your code
this.broadcastMessage( "onClick" , this) ;
}
}
If you want use a method inside the class... no problemo but now if you want
use a listener and a movieclip who extend this class :
var mc:MovieClip ; // the movieclip in the _root for example
// Inherit the custom class
mc.__proto__ = Component.prototype ;
Component.prototype.call(mc) ;
mc.addListener(this) ;
this.onClick = function ( target:MovieClip )
{
trace( "click " : target ) ;
}
If you want a better solution .. you can use my openSource framework VEGAS (
http://vegas.riaforge.org/ ) and the package vegas.util.factory.. in this
package you can find the class DisplayFactory :
http://svn.riaforge.org/vegas/AS2/trunk/src/vegas/util/factory/DisplayFactory.as
If you want test this class..
1 - download vegas
2 - install in your actionscript preference (in flash) the classpath of
vegas in AS2/trunk/src
3 - Test the examples in AS2/trunk/bin/test/vegas/util/factory :
http://svn.riaforge.org/vegas/AS2/trunk/bin/test/vegas/util/factory/
You can use the composition pattern and not the extend pattern to control a
movieclip... in my framework you can use the DisplayObject AS2 class in the
asgard.display package.
EKA+ :)
2007/2/4, David Cohn <[EMAIL PROTECTED]>:
Hey all,
Is it possible to use a "class extends MovieClip" on a pre-existing
(authored) MovieClip?
I'd like to seamlessly do something like:
class blah extends MovieClip {
public function blah() {
this.onRelease = function() {
// handle release here
};
};
};
... but I can't see how to set this up (I'm using ActionScript 2.0,
but is there a 3.0 only solution?).
If not, what do people think is the most elegant way to handle this,
e.g.:
class blah {
public function blah( caller:MovieClip ) {
caller.onRelease = function() {
(blah instance).handleRelease();
};
};
public function handleRelease() {
// handle release here
};
};
...I'd like to make this as seamless as possible for the graphic
designers.
Thanks,
--Dave
