public Jerry() //class is named "Jerry", it's an extension of the "Animal" class
    {
        image1 = new GreenfootImage("A.png");
        image2 = new GreenfootImage("B.png");
        setImage("A.png");
        blink();
    }

  public void blink()
  {
	 if ( getImage() == image1 ) // This makes the object constantly switch between
	 {		             // two images. I understand how this works...
            setImage(image2);
         }
         else
         {
            setImage(image1);
         }
   }



however, that's if I want the object to switch between two images, like a walking cycle, but this is not the case.
I feel like I need to only declare one image, then declare its transparency as a variable, something maybe like
transVariable = getTransparency()

Then, I think the code would maybe look like

public Jerry()
    {
        image1 = new GreenfootImage("A.png");
        image2 = new GreenfootImage("B.png");
        setImage("A.png");
        transVariable = getTransparency();
        blink();
    }

public void blink()
  {
	 if ( getImage() == image1 )
	 {
            setImage(image2);
            setTransparency(0);
         }
         else
         {
            setImage(image1);
            setTransparency(transVariable);
         }
   }
