I have a animation which goes to the left, but it also has to go to the right. Can I use the mirrorHorizontally in GreenfootImage to flip the images and still keep the animation and if yes, who should I do it?

private static GreenfootImage[] frame = new GreenfootImage[number of frames you have multiplied by two and add one]

public myActor()
{
    frame[0] = new GreenfootImage("firstFrame");
    frame[1] = new GreenfootImage("secondFrame");

    frame[2] = new GreenfootImage("firstFrame");
    frame[3] = new GreenfootImage("secondFrame");

    for(int i = 2; i < 3; i++)
    {
        frame[i].mirrorHorizontally();
    }
}

You could also define the images when you make the image array, but this looks more organized. There's other ways to do this, but I think this is the easiest way. All you need to do with your animation for moving right now is use the mirrored frame(s) in your animation code.

/** [number of frames you have multiplied by two and add one]*/
    private static GreenfootImage[] frame = new GreenfootImage

    
    public Leatherface()
    {
        frame[0] = new GreenfootImage("leatherface0");  
        frame[1] = new GreenfootImage("leatherface1");  
   
        for(int i = 0; i < 1; i++)  
        {  
            frame[i].mirrorHorizontally();  
        }  
    }

I have tried to use your code, but constantly gets the same error!

'(' or ' It marks the line

public Leatherface()

Were have I made an error?

Two things, in line 2, you will need to add the square brackets and the number 3 after your declaration (private static GreenfootImage frame = new GreenfootImage) and then in lines 7,8, you will need to add the file extention to your image names (like "leatherface0.png") What your doing is making an array of greenfootimages, frame being the first frame in the animation, and frame the second image, both mirrored horizontally. Animate them by alternating between frame 0 and 1.

Can I use a mirrorHorizontally with a animation?
