I'm trying to adjust the scale of an image used in a Fish Bowl scenario using a constructor, which works until I move the actor and it expands to the normal scale. How can I edit my code to keep the same size the whole time, which would ideally be a 1/2 scale?
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Goldfish here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Goldfish extends Actor
{
private GreenfootImage image1 = new GreenfootImage ("goldfish.png");
private GreenfootImage image2 = new GreenfootImage ("goldfish2.png");
private int imageCounter;
/**
* Act - do whatever the Goldfish wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
fishSwim();
checkKeys();
}
public Goldfish()
{
GreenfootImage image = getImage();
image.scale(image.getWidth()/2, image.getHeight()/2);
setImage(image);
}
/**
* Method to swap the goldfish images
*/
public void goldfishImageSwap()
{
if (getImage().equals(image1)) {
setImage (image2);
}
else {
setImage (image1);
}
}
/**
* Method to make the fish appear to swim
*/
public void fishSwim()
{
if(Greenfoot.isKeyDown("right") == true)
{
move(2);
imageCounter = (++imageCounter)%6; // change '2' higher to slow down animation
if (imageCounter == 0) goldfishImageSwap();
}
}
/**
* Method for movement via keypresses
*/
public void checkKeys()
{
if (Greenfoot.isKeyDown("up") == true)
{
setLocation(getX(), getY()+2);
}
else if (Greenfoot.isKeyDown("down") == true)
{
setLocation(getX(), getY()-2);
}
}
}
