Could someone please post the coding to make the AI (computer controlled player) to move randomly and kill the player on impact?

1 2 3 4 | if(Greenfoot.getRandomNumber(how often you want the action to happen, 2=very often 100+=less often)==0){ //action goes here} |
Is that the full coding to get the character to move randomly and kill on impact? as it seems a little short
I gave you an start. The thing I posted will let your character do something randomly
To make it kill on impact, in the players code you should put:
1 2 3 4 5 6 7 8 | public void act(){ Actor actor = getOneIntersectingObject(enemy.class); if(actor != null) { getWorld().removeObject(this); }} |
Does that move the character too?
1 2 3 4 | if(Greenfoot.getRandomNumber(5)==0) { setLocation(getX()+5, getY());} |
1 2 3 4 5 6 7 8 | public void act() { Actor actor = getOneIntersectingObject(enemy.class); if(actor != null) { getWorld().removeObject(this); } } |
1 2 3 4 5 6 7 | public void act(){ if(Greenfoot.getRandomNumber(5)==0) { setLocation(getX()+5, getY()); }} |
Thanks for your help. doing it now.
I get this message
java.lang.IllegalStateException: Actor not in world. An attempt was made to use the actor's location while it is not in the world. Either it has not yet been inserted, or it has been removed.

I have put both characters in my stage
Show me the code for both of the characters
This is the enemy
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Drone here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Drone extends Actor
{
/**
* Act - do whatever the Drone wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if(Greenfoot.getRandomNumber(5)==0)
{
setLocation(getX()+5, getY());
}
}
{
Actor actor = getOneIntersectingObject(Drone.class);
if(actor != null)
{
getWorld().removeObject(this);
}
} }
This is my player
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Dom here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Dom extends Mover
{
private int speed=5;
public Dom()
{
}
public void act()
{
checkKeys();
}
private void checkKeys(){
if(Greenfoot.isKeyDown("left")){
moveLeft();
}
if(Greenfoot.isKeyDown("right")){
moveRight();
}
if(Greenfoot.isKeyDown("up")){
moveUp();
}
if(Greenfoot.isKeyDown("down")){
moveDown();
}
} public void moveRight(){
setLocation(getX()+speed,getY());
}
public void moveLeft(){
setLocation(getX()-speed,getY());
}
public void moveUp(){
setLocation(getX(),getY() -speed);
}
public void moveDown(){
setLocation(getX(),getY() +speed);
}
{
Actor actor = getOneIntersectingObject(Dom.class);
if(actor != null)
{
getWorld().removeObject(this);
}
} }
