Remote agent/Agent logic/PicoLisp
< Remote agent | Agent logic
Remote agent/Agent logic/PicoLisp is an implementation of Remote agent/Agent logic.
Other implementations of Remote agent/Agent logic.
This is the client. For the server, see Remote agent/Simulation#PicoLisp. <lang PicoLisp># Global variables:
- '*Sock' is the TCP socket to the server
- '*Dir' is a circular list of direction structures
- '*World' holds the explored world
- '*Ball' is the ball found in current field
- '*Todo' is the list of mismatching fields and balls
