Kako pauzirati i kontrolisati animaciju u JApplet-u?

^{08.06.2010. u 09:10 - pre 169 meseci}

Pozdrav svima!

Pokušavam da napravim jednu animaciju koja simulira čekanje u redu na šalteru: ljudi čekaju, ispred njih su 3 šaltera i oni prilaze slobodnom. Simulirala sam to tako što sam crtala kružiće koji se pomeraju ka velikom krugu (on simulira šalter) i sada bih da te kružiće kontrolišem, tj. da omogućim pauziranje animacije, kao i da kružići dolaze do slobodnog šaltera. Možete pokrenuti i pogledati navedeni kod:

Evo koda za aplet:

Code:
package org.me.log;

import javax.swing.JApplet;

public class LogAplet extends JApplet {

    @Override
    public void init() {
        try {
            java.awt.EventQueue.invokeAndWait(new Runnable() {
                public void run() {
                    initComponents();
                }
            });
        } catch (Exception ex) {
            ex.printStackTrace();
            }
    }
    // TODO overwrite start(), stop() and destroy() methods
   private void initComponents() {

Trenutno vršim podešavanja i upravljanje simulacijom u LogPane2. Mislim da tu treba podešavati ponašanje animacije, tj. definisati pomeranje ovih elemenata, samo nisam sigurna kako. Nadam se da neko može pomoći.
