Introduction to Simulation League
What is the RoboCup Simulator?
What platforms does the simulation run on?
What platforms can I build players for?
Can I run a game across the Internet?
What’s all this stuff about Gentlemen’s Agreement?
Startup Soccerserver
When I attempt to run soccermonitor, I get the message ld.so: libSM.so.6: not found
When I attempt to run soccermonitor, I get the message ld.so: lib???.so.???: not found
When I start the Soccerserver, I get a message saying can not bind local address.Why?
I run sserver script, and I got the following messages:
What is the recommended directory for X11R6?
When I start Soccerserver, why do I get a message: can’t bind local address?
I tried to get Soccerserverto compile on my Linux box.
Making Clients
Why does the sample client continuously receive
How do I set up a connection to the server as non-blocking?
My clients can not get newest visual information, because a couple of messages from the server are on the queue of the socket. How do clients get the newest message from the queue?
I’m trying to run Ogalets’ or Sekine’s clients, but players do not work well. Why?
I came across FD_ZERO, FD_SET, FD_ISSET functions in the client program. What do they mean?
What is the correct behavior when a player receives the "half_time" message? Should he close the connection with a "bye" command and reconnect after a break? Does the server keep running during the half-time break?
What are "quantize_step" and "quantize_step_l" found in the Soccerserver's configuration file (server.conf)?
There are different types of parameters for stamina, recover and effort in the Soccerserver's configuration file (server.conf). How do they work?
How much stamina is given to you at every simulation cycle?
In Soccerserverversion 4.18 (sserver-4.18), there is a part "stamina -= fabs(power)". How does it work?
Human can't assign free_kicks or drop_balls upon holding the mouse click in the soccermonitor. How do I overcome this problem?
Every Soccerserverrelease has new changes to it. Where can I reference for those changes made?
What are the different versions of Soccerserver's protocols that I can use?
Tell me more about 'sense_body' command.
How do I migrate from version 3 to version 4 protocol?
What are the guidelines that will be followed by the human referee at the simulator competition?
Visual Information
Are the following two values the same?
Does it always keep |DirChng?
If the player is stationary and the ball moves from relative position (Dist, Ang) (10,15) to position (10,17) in the last simulator step (.1 second), then DirChng would be the angle of the ball motion relative to the player and DistChng would be the ABSOLUTE distance the ball traveled. Even though the ball’s distance to the player remained constant, DistChng would not be 0?
If the player moves, the vector of the player’s ABSOLUTE motion is subtracted from the ball’s ABSOLUTE motion vector. DistChng is the magnitude of the resulting vector and DirChng is its angle relative to the player’s direction?
Inside of Soccerserver
The soccerservermanual says that the magnitude of the noise in the ball motion varies in proportion to the parameter ball_rand.
The scores on the soccermonitor wrap very soon, going into negative numbers if the score gets too big. This is a problem when using the same soccerserverfor a large number of evaluations. Can I suggest using ints or longs for the scores instead of chars or shorts?
What are the units of player_size and ball_size? Does these parameters specify radius or diameter?
What are the units of player_weight and ball_weight? What are the units of wind_force and ball_weight?
wind_dir is 0 means that wind flows to north?
What are the units of maxpower and minpower?
Are the units of maxmoment and minmoment degrees?
Miscellanous
How reliable is the message transmission?
