So, im having a problem with my code. I have it so that the actor by default faces right, but i need it o face left when i press "left", but it keeps looking side to side 
public void move()
    { 
        int y = getY();
        int x = getX();
        
        if(Greenfoot.isKeyDown("Left") && canMoveLeft())
        x-=STEP;
        turn (180);
        getImage().mirrorVertically();
        
        if(Greenfoot.isKeyDown("Right")&& canMoveRight())
        x+=STEP;
        
        setLocation(x, y);
    }

Use setRotation instead of turn. Also, you will need to set the rotation in the "Right" key detected code also (line 13). As a side note, I do not believe that "Right" and "Left" should be capitalized.

Ok, thank you Lord Danpost. But now the actor stays upside down and only looking left, after looking left for the first time. What could i have done wrong?

nevermind i ended up fixing it 
public void move()
    { 
        int y = getY();
        int x = getX();
        
        if(Greenfoot.isKeyDown("left") && canMoveLeft())
         { x-=STEP ; setImage("0.png"); setRotation (180); getImage().mirrorVertically();}
      
        if(Greenfoot.isKeyDown("right")&& canMoveRight())
        {x+=STEP; setImage("0.png"); setRotation(0);}
        
        setLocation(x, y);
    }
