e.getBearing() returns angles with errors

[feistybot99]

Hi

I am relatively new to Robo as well as Java but I have a question:
When I use e.getBearing() the angle returned has a significant error, like around 25 degrees. I thnk its because the the beam width is too wide. Its around 30 deg. So I can't get an accurate fix on the enemy. How can I make the beam width narrower or otherwise get a more accurate bearing?

Another question, how can I print data to the screen or console window? The program seems to ignore out.println

kind regards,
andrew

Never mind, i found the problem with the angle error. I still have the question about printing out to the screen. Do I have to show the console window first? Let me know.

I think when you print to the console (via System.out.println, for instance),
the text you specified can be seen by clicking on your robot's name over on the
side of the battle screen. This is the same window one uses to turn on and off
painting. Doing so should open a status window with some tabs, and one of those
tabs will show what you've printed.

I forget the actual name of the window, but I hope this is helpful.

Either open up the console window by clicking on your robot's name in
the battle display (all the System.out.println() goes there) or you can
open your robots window and enable painting, which lets you display
directly on the battlefield.

Take a look at robowiki.net for implementation details - there are lots
of open source bots which use painting for all sorts of uses.

Hope this helps
