Robocode game.

[CocoDan]

Anyone here use Robocode? Search for it.

[Aphius]

Hm... I'm learning Java right now, so maybe I'll have a look at it.

[dougdrums]

don't you just love the way sun can count! "Java 2 version 1.3"

[Kaniaz]

Haven't you heard? It's the new "Elite Company" numbering system! It works on the basis you increase the number several times without making any changes to make the software look better than it really is! Works like a charm!

[dougdrums]

Eh, this is pretty fun.

[CocoDan]

Well you can program bots and some of them kick ass. http://www.robocoderepository.com/ http://www-106.ibm.com/developerworks/java...ary/j-robotips/

[CocoDan]

HAHAHA!!! You can't fire higher than three! And you should extend to AdvancedRobot. You can then move radar, gon, and tank independently.

[dougdrums]

Yeah, figured out the fire no more than three thing. Fixed.

[CocoDan]

Hahaha, Gary Coleman.

[dougdrums]

lmao: method summary: getLife() Deprecated.

[dougdrums]

haha, no, it was on here: http://robocode.alphaworks.ibm.com/docs/ro...code/index.html

[CocoDan]

You should check out the winning bots. The coding records everything and targets expected future coordinates of enemy bots. Rapture is a great example of a 1 vs. 1 bot. It dodges bullets and has an excellent gun. http://www.robocoderepository.com/BotDetail.jsp?id=15 The site is messed up right now, I had to log in using an admin's password to find it.

[dougdrums]

Well, I'll put in the cosine rule (http://www.mathsdirect.co.uk/pure/purtuttrisin.htm) and make it circle around the enemy tonight. That should give it a little more accuracy than the guessing code I used in 0mg.

yeah, saw that. Neat stuff.
