 Hi, I'm new to this thing. I'm currently trying to implement something onto my corrupted version of Walls. I have HeadOnTargeting. What I'm trying to do is, if the other robot is disabled, my robot (Ziska) will stop, turn the gun to the enemy, and fire. What I currently have is
-<pre>
+<syntaxhighlight>
 public void onScannedRobot(ScannedRobotEvent e) {
      if (e.getEnergy()<0.1) {
@@ Line 56: / Line 56: @@
+     }
+}
-</pre>
+</syntaxhighlight>
 What will happen is, my robot will move in little jolts, moving its gun around, and firing sporadically. Eventually it will hit the thing but it doesn't work too well in melee, and wastes time and energy. I have experimented with various e.getBearings and e.getHeadings but nothing really works. What would be the best way to finish off a disabled robot in a single shot?

 I don't have much experience with ending turns in event handlers, but I think this is what you're trying to do (untested):

 public void onScannedRobot(ScannedRobotEvent event) {

 Sorry for being new to this and programming in general(wrote my first bot/java program Jan 17), but i think this is the right place to put this. I've been working on my first bot, and it works pretty well for what i want it to do except for one thing: Whenever it starts, if it starts with the radar facing the enemy or sees the enemy before it has a chance to finish turning its gun, the gun stops turning halfway and cripples the robot. I tried putting the boolean stopWhenWeSeeRobot = false; from corners but it didn't help, I'm not sure if i'm using it the right way. Is there a way i can keep this from happening? Here is the code:
-<pre>

 public class MagicD2 extends AdvancedRobot{

 Being new is no reason to be sorry ;-). The stop method you call on the "onScannedRobot" event handler, not only stops the bot, it also stops the gun and radar. A quick way to fix your problem is to retrieve the remaining gun turn before stopping. Something like this:
-<pre>
+<syntaxhighlight>
 	public void onScannedRobot(ScannedRobotEvent e) {
 		double bulletPower =(400/e.getDistance());
@@ Line 236: / Line 236: @@

 As you can see, I turned the gun right and not left (as you do), this is because getGunTurnRemaining will give how much turn remains to the right, you could set it to turn left, but then use "-turn" instead. Although that should fix your problem, I recommend reading some of the basics on the wiki before you code to much, since information is being migrated from an older wiki to this one, there are still things that are better read from the [http://robowiki.net| old wiki]. I recommend creating an account on this wiki, that would give a place where you can chat without being afraid of placing something on a wrong place. Have fun Robocoding, and beep if you need more help -[[Zyx]] 20:49, 19 January 2009 (UTC)

 Thanks, i had realized that the stop() was the problem but I wasn't sure how to deal with it. I'll be sure to check out the old wiki. Also, there is another strange thing about this robot. Every now and then it will stop moving and begin to track the enemy with a narrow beam while constantly firing. I am not sure why it does this as I did not intend to make the radar track the enemy, just spin around and update the robot about the enemy's position. Luckily it seems to help the robot alot. Does anyone know why it might do this?  -CrazyBassoonist
-Your welcome. About the radar, I don't know exactly what makes your radar track the enemy, it may be just a little bit of luck. Check the [Radar] page for more information on how to code your radar lock, there is one looping radar as well. --zyx 21:10, 19 January 2009 (UTC)
