5 errors, who can help me?

Can someone tell me the problem here?? I dont get it :S

5 problems (5 errors) Compile Failed (-1)

This is my code:

package MyRobots;

import robocode.HitRobotEvent; import robocode.Robot; import robocode.ScannedRobotEvent;

import java.awt.*;

public class Yeah extends Robot {

public void run() { // Kleuren setBodyColor(Color.black); setGunColor(Color.black); setRadarColor(Color.black); setBulletColor(Color.black); setScanColor(Color.cyan);

// ...

   turnRadarRightRadians(Double.POSITIVE_INFINITY);
   do {
       // Check for new targets.
       // Only necessary for Narrow Lock because sometimes our radar is already
       // pointed at the enemy and our onScannedRobot code doesn't end up telling
       // it to turn, so the system doesn't automatically call scan() for us
       // [see the javadocs for scan()].
       scan();
   } while (true);

}

public void onScannedRobot(ScannedRobotEvent e) {

   double radarTurn =
       // Absolute bearing to target
       getHeadingRadians() + e.getBearingRadians()
       // Subtract current radar heading to get turn required
       - getRadarHeadingRadians();

   setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

   // ...

}

give me the source code And Ill Try To fix it

package MyRobots;

import robocode.AdvancedRobot; import robocode.ScannedRobotEvent; import robocode.util.Utils;

public class Yeah extends AdvancedRobot {

public void run() {

   turnRadarRightRadians(Double.POSITIVE_INFINITY);
   do {
       scan();
   } while (true);

}

public void onScannedRobot(ScannedRobotEvent e) {

   double radarTurn =
       // Absolute bearing to target
       getHeadingRadians() + e.getBearingRadians()
       // Subtract current radar heading to get turn required
       - getRadarHeadingRadians();

   setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

}

}

Nevermind, i fixed it already. Still thanks for your help

now show everyone the robot

It now only has a radar :P

Still have to add the movement and targeting haha

http://robowiki.net/wiki/Stop_And_Go_Tutorial http://robowiki.net/wiki/Anti-Gravity_Tutorial http://robowiki.net/wiki/GuessFactor_Targeting_Tutorial do you have enough time left to implement all these

I think so, i tried Stop_And_Go and I only get one error... this is the error:

1. ERROR in C:\robocode\robots\MyRobots\Yeah.java (at line 31) setAhead(direction*36*Math.max(0,Math.signum(prevEnergy-e.getEnergy()))); ^^^^^^^^^ direction cannot be resolved to a variable

And this is the source: package MyRobots;

import robocode.AdvancedRobot; import robocode.ScannedRobotEvent; import robocode.util.Utils;

public class Yeah extends AdvancedRobot {

public void run() {

   turnRadarRightRadians(Double.POSITIVE_INFINITY);
   do {
       scan();
   } while (true);

}

static double prevEnergy = 100.0;

public void onScannedRobot(ScannedRobotEvent e) {

   double radarTurn =
       // Absolute bearing to target
       getHeadingRadians() + e.getBearingRadians()
       // Subtract current radar heading to get turn required
       - getRadarHeadingRadians();

   setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

{

	//energy monitoring
 	if(getDistanceRemaining()==0.0){
	setAhead(direction*36*Math.max(0,Math.signum(prevEnergy-e.getEnergy())));

}

} } }

good because it doesn't get any easier from here

I understand :P

The problem at the moment is that I can't solve the one problem in here

What You Want To Do Is Say. Remember The Solution To The Error Repeatedly. And Then The Answer Will Come To You. In Other Words Rememberance

How far are you

Not able to find a solution.. :(

Read The Tutorials as CAREFULLY as possible

Finally. Solved the problem :D Now i have a working radar and the Stop And Go movement.

Do I now only have to add the GuessFactor Targeting?

Skip Anti Gravity And Go straight To guessfactor targeting

Where do I have to add the new class Wave Bullet?

examine this code carefully

import java.awt.geom.*;
import robocode.util.Utils;
 
public class WaveBullet
{
	private double startX, startY, startBearing, power;
	private long   fireTime;
	private int    direction;
	private int[]  returnSegment;
 
	public WaveBullet(double x, double y, double bearing, double power,
			int direction, long time, int[] segment)
	{
		startX         = x;
		startY         = y;
		startBearing   = bearing;
		this.power     = power;
		this.direction = direction;
		fireTime       = time;
		returnSegment  = segment;
	}

I am sure this is not good, but where am i going wrong?

import robocode.AdvancedRobot; import robocode.ScannedRobotEvent; import java.awt.geom.*; import robocode.util.Utils;

public class WaveBullet { private double startX, startY, startBearing, power; private long fireTime; private int direction; private int[] returnSegment;

public WaveBullet(double x, double y, double bearing, double power, int direction, long time, int[] segment) { startX = x; startY = y; startBearing = bearing; this.power = power; this.direction = direction; fireTime = time; returnSegment = segment; }

public class Yeah extends AdvancedRobot { public void run() {

  turnRadarRightRadians(Double.POSITIVE_INFINITY);
  do {
      scan();
  } while (true);

} static double prevEnergy = 100.0; public void onScannedRobot(ScannedRobotEvent e) {

  double radarTurn =
      // Absolute bearing to target
      getHeadingRadians() + e.getBearingRadians()
      // Subtract current radar heading to get turn required
      - getRadarHeadingRadians();

  setTurnRadarRightRadians(Utils.normalRelativeAngle(radarTurn));

{ //energy monitoring

	if(prevEnergy > (prevEnergy = e.getEnergy()) && getDistanceRemaining() == 0.0);

} } }

Just compile it and see what happens
