Avoider Game: method

Alright, so it seems the error is here:
You probably want it so that if the enemy is touching the player, the game ends, correct?
What you're doing is ending the game as soon as a enemy appears.
Try this code:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Enemy here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Enemy extends Actor
{
/**
* Act - do whatever the Enemy wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
setLocation(getX(), getY() + 1);
Actor avatar;
avatar = getOneIntersectingObject( Avatar.class );
{
AvoiderWorld world = (AvoiderWorld) getWorld();
world.endGame();
world.removeObject(avatar);
}
}
}
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Enemy here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Enemy extends Actor
{
/**
* Act - do whatever the Enemy wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
setLocation(getX(), getY() + 1);
Actor avatar;
avatar = getOneIntersectingObject( Avatar.class );
if(avatar != null){
AvoiderWorld world = (AvoiderWorld) getWorld();
world.endGame();
world.removeObject(avatar);
}
}
}
After testing out the game with that code on my computer, it works; however, I noticed that when the enemies hit the bottom of the screen, they don't go away.
If you want to change this so they disappear when they hit the bottom, you can include this code at the end of the act method:
if(getY() > getWorld().getHeight()-5) {
getWorld().removeObject(this);
}You need to login to post a reply.
