Hi Kyle,

thanks for your answers.

This is fine, but we need a way to do the above with C# code, otherwise it's
not very useful. Clearly one of the main advantages of the simulation as
opposed to the real system, is that collecting training data is cheap, and
based on these data one can use various learning techniques for adapting
whatever algorithms one is developing. Unless there is an
automatic/programmable way to set the objects in the desired positions,
there is no hope that one can use such techniques for learning how to play
soccer. I believe it would be really a pity if we are not given this
possibility --- in fact we assumed that this would be the case when we
registered for this event, and it would be very disappointing if it turns
out that this option is disabled. Whatever techniques one uses for algorithm
design, I believe that there should be a programmable way to test the
developed algorithms without interacting manually with the simulator
graphics.

thanks,
Nikos
