Hi there, I have packaged robocode game this weekend. The idea is to program a battle tank in Java using this API, and make it fight against other robots. There is a limited amount of time and power your robot can spend on actions like moving, firing or scanning the battlefield with the radar, and the challenge is to find the right balance. There are several sample robots included in the game, which you can use as a base for your own robots, and as adversaries. At first, you would place a couple of targets of class SittingDuck on the battlefield to check that your robot is able to find targets and shoot at them. Then, you'd make your bot fight against some simple robots from the sample package. Plenty of advanced robocode resources are available at robocode home page. I really wish we could hold an OpenPandora robocode competition sometime this year, if enough people are interested. For now, feel free to play with the game and vote. In a few weeks, if there are enough votes in favor of the competition, we will discuss the rules and define the timeline.
