import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Knight1 here. * * @author (BradH) * @version (a version number or a date) */ public class Knight1 extends GoodTroops {private int Walk = (9); /** * Act - do whatever the Knight1 wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { move(2); Walk -- ; if(Walk == 0) { setImage("image-GoodKnight2.png"); } hello, I am trying to get my Knight1 class to change the Image to GoodKnight2.png once walk==0; GoodKnight2 is an image I have uploaded into my project, previously have just been removing my knight1 class from the world and adding a new class that has the GoodKnight2.png image and then removing that class and getting knight1 to appear again to give it an animated look. The problem with that is I can not make A death Image because the classes get removed from the world everytime walk == 0; Back to my main question in the code above when I run the game an error pops up saying that it can not find image GoodKnight2.png which is the name of the image that I have uploaded into my project, why can't it find this image. Thanks for your time.

if you cant find this image the filename of it could be wrong or you could have saved it to a wrong place. You have to save the image in images in your scenario

I imported the image into my game it was a png I created in another program, it is listed as GoodKnight2 when I look at the setimages. I tried another image from the images imported in my game bit it also failed to work so maybe there is something wrong in my code.

Maybe you should share what code you tried and we could possibly help.

Maybe you meant 
setImage("GoodKnight2.png");
// instead of
setImage("image-GoodKnight2.png");

One more quick question how would I get Knight1 image to come back and keep on switching between the two, would I use a loop? To keep reverting back to the first Image then restarting over.

Make the following changes in the class 
// change
private int Walk = (9);
// to
private int Walk = (0);
// add the following class array
private static final String[] IMAGES= { "GoodKnight1.png", "GoodKnight2.png" };
// add the following class int
private static final int RATE = 9; // adjust as neccessary
// Then, change the following
Walk -- ;
if(Walk == 0)
{
    setImage("image-GoodKnight2.png");
}    
// to this
Walk = (Walk+1)%(RATE*IMAGES.length);
if (Walk%RATE==0)
{
    setImage(IMAGES[Walk/RATE]);
}
This will animate your actor. You can list all the images you want in the array 'IMAGES', and even have the same image name in there more than once; as long as you list them in the order they are to appear. And the value of 'RATE' can be adjusted to suit the speed of your scenario (the initial value of 9 was retained in the code above).

private static final String[] IMAGES= {"GoodKnight 1.png", "GoodKnight2.png" };
private static final int RATE = 9;
Those need to moved up near where you have "private int Walk = (0);"
