Hi again! My query is about whether or not you can check if the actors image is looking left, or looking right (in a sense). The code I'm using to flip the actors image is this:

GreenfootImage img = getImage();
img.mirrorVertically();
setImage(img);

But if I use this in the move() method, I could be pressing the right button and it would flip the image every time that I press it. So again, my question is about whether or not you can check what direction the image is facing. Any help would be appreciated! Thanks!

If you cannot, do you think I should just copy the image file and rotate it?

You could compare the image to the original image to see if it is the same (not flipped) or not (flipped). However, you can also save a reference to both versions and use them as different images.

private GreenfootImage imageRight, imageLeft;

//in constructor
imageRight = new GreenfootImage("filename.png");
imageLeft = new GreenfootImage("filename.png");
imageLeft.mirrorHorizontally();

Ah I see! That'd work quite well actually. Thanks again!

Oh there is something I forgot to mention, sorry! I have already created the images for the game, so would I still use "new GreenfootImage("")"?

You mean you set the image with a right click on the class? Then you can still do it like this or use 'getImage()' instead.

Ah right, thank you again!

Hi! Sorry I just tested the scenario and when I place the actor in the world I get the following error: java.lang.IllegalArgumentException: Filename 'idle1.png' has the wrong case. It should be: 'Idle1.png' I ended up setting the actors image to unspecified as it made things less complicated, and this is the code in the constructor now:

public Hero(){
        //setting Images
            //idle1
        GreenfootImage idleOneRight = new GreenfootImage("idle1.png");
        GreenfootImage idleOneLeft = new GreenfootImage("idle1.png");
        idleOneRight.mirrorHorizontally();
            //idle2
        GreenfootImage idleTwoRight = new GreenfootImage("idle2.png");
        GreenfootImage idleTwoLeft = new GreenfootImage("idle2.png");
        idleTwoRight.mirrorHorizontally();
            //shoot1
        GreenfootImage shootOneRight = new GreenfootImage("shoot1.png");
        GreenfootImage shootOneLeft = new GreenfootImage("shoot1.png");
        shootOneRight.mirrorHorizontally();
            //shoot2
        GreenfootImage shootTwoRight = new GreenfootImage("shoot2.png");
        GreenfootImage shootTwoLeft = new GreenfootImage("shoot2.png");
        shootOneRight.mirrorHorizontally();
        //setting velocity
        velocity = 0;
        //setting Hero image
        setImage(idleOneLeft);

Any ideas?

Well, if the name of the image is "Idle1.png", then the name in your code should be "Idle1.png" instead of "idle1.png", too.

OHHH! I didn't see the capital... oops. Thanks again!

Is there a way to check if the actors image is flipped or not?
