I have been asked to remove the randomly moving around ducks from the our SIM on ReactionGrid. I was “Cooking the server” and as the server was donated to us I felt obliged not to take advantage.

Thanks once again for the people at ReactionGrid for providing us with a server to use for HomeCamp, lets see if we can improve its use for the next HomeCamp.

HomeCamp blog post to follow and a twitter search library post to follow when I get a few minute

The first iteration  randomly chooses a direction (North, South, East or West)  and moves one meter. This repeated every second. I had to introduce a 270m boundary otherwise the ducks had a habit of trying to change sims.

The second (and current) iteration of Duck allows them to be more interactive. If you talk while near the duck, it becomes scared of you (-1 modifier) however if you touch it it likes you (+1 modifier). The distance and direction it moves is connected to the accumulated modifier. If the modifier is positive it moves towards  you, if it is negative it moves away from you.
