TRacking ojects
You can make an Actor variable.
Then, once you aquire your target, you can look at the getX() and getY() of that Actor to see where it is.
import greenfoot.*;
import java.util.List;
public class Tracker extends Actor
{
Actor target = null;
public void act()
{
// no target aquired, wait for one
if ( target == null )
{
// Look for targets
List<Actor> targets = getObjectsInRange(100, Actor.class);
if ( !targets.isEmpty() )
{
// If possible targets seen, choose one at random.
int choice = Greenfoot.getRandomNumber(targets.size() );
target = targets.get(choice);
}
}
//target acquired. Seek!
else
{
// Close 90% of distance to target. See Achilles/Tortoise.. ;)
setLocation( getX() + (target.getX()-getX())/10 , getY() + (target.getY()-getY())/10 );
}
}
}
thats great
==how would you code it if there was only one target eg player ??
sorry answerd my own question big help thx :):):):):)
If you're using Greenfoot 2.2, you can use the all new "turnTowards(int x, int y)" method, which is defined in Actor.
