Re: listener working example

Author: michal.bida

This is working example of bot, that has defined two listeners - one for counting the frags and second for logging text messages (They will appear in user part of agent logs). The frag variable can be observed through introspection.

package simplebot;

import cz.cuni.pogamut.Client.Agent;
import java.util.logging.Level;
import java.util.logging.Level;



import cz.cuni.pogamut.Client.RcvMsgEvent;
import cz.cuni.pogamut.Client.RcvMsgListener;
import cz.cuni.pogamut.MessageObjects.*;
import cz.cuni.pogamut.introspection.PogProp;

/**
 */
public class Main extends Agent {
    
    @PogProp boolean turn;
    
    @PogProp boolean hitWall;
    
    @PogProp boolean shooting;
    
    @PogProp int frags = 0;

    /** Creates a new instance of agent. */
    public Main() {
        super();
        /**
         * set level of logging - see logging documentation, now you will see only more relevant things
         */
        this.log.setLevel(Level.INFO);
        this.platformLog.setLevel(Level.INFO);
    }
    
    RcvMsgListener myListener = new RcvMsgListener() {

        @Override
        public void receiveMessage(RcvMsgEvent e) {

            PlayerKilled pk;

            pk = (PlayerKilled) e.getMessage();
            if (pk.killerID == getMemory().getAgentID()) {
                frags += 1;
            }
        }
    };
    
    RcvMsgListener myChatListener = new RcvMsgListener() {

        @Override
        public void receiveMessage(RcvMsgEvent e) {

            GlobalChat gc;

            gc = (GlobalChat) e.getMessage();
            getLogger().info("Message: " + gc.string);

        }
    };

    @Override
    protected void postPrepareAgent() {
        this.getBody().addTypedRcvMsgListener(myChatListener, MessageType.GLOBAL_CHAT);
        this.getBody().addTypedRcvMsgListener(myListener, MessageType.PLAYER_KILLED);
    }

    /**
     * Main method of the bot's brain - we're going to do some thinking about
     * the situation we're in (how it's unfair to be the bot in the gloomy world
     * of UT2004 :-).
     * 
     * Check out the javadoc for this class - there you find a basic concept
     * of this bot.

    @Override
    protected void doLogic() {

        Player player = memory.getSeePlayer();
        NavPoint bod = memory.getSeeNavPoint();
        hitWall = memory.isColliding();
        if (hitWall) {
