Java Sprite animation

[mrhid6]

Hello i was wondering how i can animate using the drawImage of 3 images

so i have image1.png image2.png and image3.png

the images have a stick man on it walking the images contain transparency as well

any ideas?

[sunde887]

A suggestion is to have an array of images, and a counter which goes through them (this may not be the best approach, but it's my thought)

private Image[] images = new Image[3];
private int current = 0;
public Image getNextImage(){
  if(current==images.length){
    current=0;
  }
  return images[current++];
}

ok so how could i do this in a loop?

[sunde887]

Each time you want to draw to the image/panel/whatever you are drawing to, you can call this method. Maybe use a Swing Timer and have it continuously draw the next method.

ok got it sorted thanks i used a swing timer to switch between frames

[mrhid6]

Ok so the swing timer is taking up to much memory in terms of file space and the ram memory how can i load an animated gif on the drawimage thing i have used imageIcon but it fails to load lots of images at the same time ..

here is my scenario i have a player class and is created by another class serval times

import java.io.*;
import javax.imageio.*;
import java.net.*;
import java.awt.*;
import java.awt.image.*;
import javax.swing.*;

public class player
{

    private Image walk_0,walk_1,walk_2,walk_3;

    private Image playerImage_still;

    public boolean walking = true;
