Displaying Images
@Matt, that class code is flawed, so read the whole discussion carefully. I will re-post the corrected code, here (shortly).
I believe this will work (but it is not tested)
Create a class (sub-class of Actor) called 'GameOver' and copy/paste the following into it (replacing what was there).
You add it from the world class with
import Greenfoot.*;
import java.awt.Color;
public class GameOver extends Actor
{
String msgTxt;
World world;
public GameOver(World w)
{
this("GAME OVER", w);
}
public GameOver(String txt, World w)
{
msgTxt = txt;
world = w;
updateImage();
}
private void updateImage()
{
GreenfootImage image = new GreenfootImage(world.getWidth(), world.getHeight()); // or whatever size you want the object
image.setColor(Color.cyan); // color of your choice
image.fill();
GreenfootImage txtImg = new GreenfootImage(msgTxt, 36, Color.black, new Color(0, 0, 0, 0)); // colors and font size of your choice
image.drawImage(txtImg, (image.getWidth() - txtImg.getWidth()) / 2, (image.getHeight() - txtImg.getHeight) / 2);
// whatever else you might want to do for the image
setImage(image);
}
}addObject(new GameOver(this), getWidth() / 2, getHeight() / 2);
// above for center screen (you can adjust location, if you desire)
// or
// for something other than 'GAME OVER' as text
addObject(new GameOver("YOU WIN", this), getWidth() / 2, getHeight() / 2);
All that code, when you could of just created an image which would be used as your "game over" screen, and add that object to the world after a certain action has been taken.
in other words, create a class which will be the image you want to display, then when the action has been preformed, you simply call "addObject(new GameOver.class, x,y);
@IsVarious, that is exactly what this code does, but it has a bit of flexibility (in that the message does not neccessarily have to be 'GAME OVER').
Nice, although your approach may work better, I think sometimes simpler is easier for new programmers to grasp.
In any event, two thumbs up :)
Hi, Im gonna give both methods a go, .
I dont know how I would use the second method for the Winner sign as it needs to appear after a particular actor has hit a particular co-ordinate, thankyou for your help.
This however doesnt work, something to do with identifiers
if (getX() == 30 && getY() == 19)
{
List getSCORE = getWorld(). getObjects (SCORE.class);
if (!getSCORE.isEmpty())
{
SCORE currScore= (SCORE) getSCORE.get(0);
currScore.updateScore(20);
}
{
addObject(new LevelComplete.class(),10,10);
}
Greenfoot.stop();
