problema drag and drop

**izzusan** · 20-09-2010, 11:18

ciao ragazzi sto creando un giochino x la mia tesi...

per ora è molto semplice:
ci sono dei cubi che scendono, io devo trasportarli e metterli in un contenitore. una spece di puzle.

x ora funge tutto il problema che ho unsato una funzione :

enemy.moveDownABit();

dove enemi e il mio cubo ke scende è ha un suo file molto semplice:

package
{
import flash.display.MovieClip;
public class Enemy extends MovieClip
{
public function Enemy( startX:Number, startY:Number )
{
x = startX;
y = startY;
}

public function moveDownABit():void
{
y = y + 0.1;

}

}
}

il problema ke quando comincio il drop lui nn si verma continua a scendere... anche quando lo aggangio al mio target continua a scendere.... come posso fare?

questo è il codice principale:

package
{
import flash.display.MovieClip;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.ui.Mouse;
import flash.events.MouseEvent;
import flash.display.DisplayObject;
import flash.display.Sprite;

for each ( var enemy:Enemy in army )
{

enemy.moveDownABit();

if ( avatar.hitTestObject( enemy ) )
{
gameTimer.stop();
}
}

}

}
}

vi prego aiuto sto impazzendo!

Puoi aggiungere una Proprietà alla Classe Enemy.

esempio:

Codice PHP:


public var canMove:Boolean = true;

La imposti su False quando lo "acchiappi":

Codice PHP:


function pickUp(event:MouseEvent):void {

    event.target.canMove = false;

    .....

    .....

    .....

La imposti su True quando lo "rilasci":

Codice PHP:


function dropIt(event:MouseEvent):void {

    event.target.canMove = true;

    .....

    .....

    .....

E la valuti al movimento:

Codice PHP:


public function moveDownABit():void {

    if (this.canMove == true) {

        y = y + 0.1;

    }

}
