aha, but that's the beauty of having a human judge as the decider, they can
tell what a bot hit. If it hit a wall then from the bots point of view
nothing changes, the bot backs up and heads off in another direction. If
the bot hits another bot then one of them is going to get picked up and
moved. Probably in either case the bot should back up and take stock of
it's situation, either it hit a wall in which case whatever it was chasing
is probably hiding behind it so it needs to do some navigation, or it hit a
bot in which case the bot got moved and so the hunter should try and
"re-acquire" a new target. Of course similar arguments apply for bots that
are currently avoiding the hunters.
To make things even simpler The "dead" prey bot could be cycled off and on
again to reset it.
The reason that I find paper-Rock-Scissors so interesting is that all of the
bots are on an equal footing, all of them have to find a balance between
hunting and hiding and do both at the same time. It's a lot more
"intellectual" than Sumo Wrestling which basically comes down to who ways
the most, and who has the lowest gear ratio.
There are some really interesting strategies that can arise.
The timid paper sits quietly with it's transmitter of and when it sees a
lone rock wandering round it charges at it screaming
"paper-paper-paper-paper-paper"
The defensive scissors runs around avoiding rocks like the plague, and with
any luck might find the odd paper.
The aggressive rock charges after scissors and completely ignores paper and
just tries to mush scissors, occasionally it gets caught by a paper and done
in.
Which strategy works the best is undefined until the end of a particular
game. it depends on what your opponents do. Of course there is always the
possibility that the bots will modify their behaviour based on what the
others are doing and this is where it gets really interesting. Suddenly how
you program your bot becomes very important.

| (...) Well, yes there is. If there's objects besides robots which can be hit, robots need some way of telling the difference between "I hit you!" and "I hit a wall!". (26 years ago, 3-Dec-98, to lugnet.robotics)
