this is protocol used in networked games, currently in early alpha state, and is subject to changes; see the following changelog for more info: 2024/04/19: first draft ------ notes: currently there isn't a way to select settings or if you'd like to play with AI or human, i'd like to later add a handshake message which allows some degree of customizition while also rejecting connections made by "non-clients" ------ a session begins with a connection to the server, you will be greeted with: CONN n where n is the connection number; currently, first user gets to play as "the trapper", while the second one plays as "the glenda". there will be a way to select the player you are playing as in next revisions. afterwards, if there is no players are online to play with, you will recieve the following message: WAIT clients SHALL not send any other messages into the connection until the servers sends the next message. once another client have been connected, you will receive: INIT which will indicate a new game has started, followed by some lines in the form of: w x y and exactly one: g x y first message means there is an wall in location x, y in the grid. while the other one means glenda's location is in x, y in the grid. once location of glenda and all walls have been sent, you shall recieve: SENT which may be taken for the game start. next, the player whose turn is to play will be sent: TURN "trapper" is expected to put a wall, in a empty (no glenda nor wall there) cell, with the following message: p x y if there is a wall in x, y in the grid, client will be warned with: WALL x y or if glenda is there, GLND x y where x and y is the same as user input, re-printed to aid debugging. "glenda" shall move in one of six directions NE, E, SE, SW, W, and NW (which means, north east, east, south east, south west, west and north west respectively) in the following format: m d where D is one of six direction (NE, E, ...) after a sucessful move both clients are notified with SYNC message; if move have been done by "trapper": SYNC t x y where t is the turn number and x, y are the position of new wall. if "glenda" have been moved: SYNC t d where t is turn number and d is the direction (NE, E, ...). game will contiune until either "glenda" manages to escape the map, or "trapper" sucessfully traps "glenda". if a game has ended or not is decided by the server. clients should not end the game before server tells them to do so, once the game is over, server will report it as: GWON indicating the glenda have managed to escape or GLOST which means glenda is trapped. once a game is finished, server closes connections to both clients. clients willing to play another match must reconnect.
