AS3: Aiuto richiamo classe

**uomoragno2** · 23-03-2011, 13:17

Ciao a tutti,
sto iniziando a vedere flash e l'uso delle classi, vorrei avere un grande chiarimento.
Io sto richiamando un file .as (sotto riportato) che mi consente di importare nel filmato un campo di testo ridimensionabile.
Il richiamo lo faccio mettendo il nome della classe dentro le proprietà del filmato principale, se io invece volessi richiamare o meglio "avviare" la classe tramite pulsante, come dovrei fare?

codice:

package {
 
	import flash.display.Sprite;
	import flash.display.MovieClip;
	//for text format
	import flash.text.TextField;
	import flash.text.TextFormat;
	import flash.text.TextFormatAlign;
	import flash.text.TextFieldType;	
	import flash.text.AntiAliasType;
	
	import flash.events.MouseEvent;
	import flash.events.FocusEvent;
	import flash.utils.Timer;
	import flash.events.TimerEvent;
 
	public class ResizableTextField extends MovieClip {
 
		private var textCustomField:TextField;
 
		//handles
		private var square1:Sprite;
		private var square2:Sprite;
		private var square3:Sprite;
		private var square4:Sprite;

		{
			
		}
		public function ResizableTextField()
		{
			
			//text format set

non per dire eh

ma dovresti postare la classe principale...questa serve a poco per aiutarti

**uomoragno2** · 24-03-2011, 10:40

Questa è l'unica classe che ho.
Richiamo la classe da scena1 ma vorrei richiamarla tramite un pulsante.
La classe sta dentro un file .as

??

**uomoragno2** · 25-03-2011, 12:20

Qualcuno sa darmi una mano?

Se uso questo non funziona:

codice:

miopulsate.addEventListener(MouseEvent.CLICK, ResizableTextField);

Non capisco come risolvere.

Il richiamo lo faccio mettendo il nome della classe dentro le proprietà del filmato principale, se io invece volessi richiamare o meglio "avviare" la classe tramite pulsante, come dovrei fare?

Codice PHP:


pulsante.addEventListener(MouseEvent.CLICK, aggiungiClasse);



function aggiungiClasse(evento:MouseEvent):void

{

    var miaClasse:ResizableTextField = new ResizableTextField;

    addChild(miaClasse);

}
