Overview

This is the API document for ColorFightII

Colorfight

The Colorfight object holds all the useful information for the game.

game = Colorfight() will create the instance. You should always have this object for the game.

After instantiate the object, you can access the attributes like game.uid, and use the methods like game.update_turn()

attributes of Colorfight

• uid

  Your user id when you join the game. 0 before you join the game.

• turn

  Current turn number, starts with 0.

• max_turn

  Turn number that this game will last.

• round_time

  The time in seconds the player have to take actions between each round.

• me

  User object for you. Invalid before join the game.

  This is a useful object. You could do me = game.me after you do game.update_turn() so that you can access the information of your bot.

• users

  A map of User objects. key is uid and value is the User object.

  game.users[1] will give you the User object of user with uid 1.

• error

  A map of error string. key is uid and value is a list of error strings for this user from last round

  Your action could fail due to many reasons. This is the error messages from last round. You can do print(game.error[game.me.uid]) to print out all your error messages to debug you bot.

• game_map

  GameMap object for current game map.

  This is an important object that saves all the information of the game map, including all the cell info. You can save a shortcut just like me, with game_map = game.game_map

methods of Colorfight

• .get_gameroom_list()

  return a list of data of gameroom on the server

  You can use this in the script to choose gameroom rooms = game.get_gameroom_list() rank_room = [room for room in rooms if room["rank"]]

• .connect(room)

  Establish connection to the server. room is the name of the game room you want to join.

  You should always connect first. game.connect(room = "public") is the default way to connect to the default public room

• .update_turn()

  Wait until next turn, and update the game info. This method will change the data of Colorfight object.

  You should use game.update_turn() after you send the command list to get the latest info from the game.

• .register(username, password, join_key = "")

  Register to the game with username and password. Duplicate username is not allowed. If you already joined the game and somehow disconnected. Using the same username and password will allow you to continue with previous account. join_key is required if the gameroom is locked, otherwise you do not need to specify the argument. Returns True if success.

  This should happen after you connect to the server and before you start you game loop.

• .attack(position, energy)

  Returns a string for attacking a certain position. position should be a Position object or a tuple, energy should be an integer.

  ** This string is a command that you should put in your command list and send with send_cmd **

  example: game.attack((2, 2), 250) will spend 250 energy to attack (2, 2). It's equivalent to game.attack(Position(2, 2), 250).

• .build(position, building)

  Returns a string for build a building on a certain position. position should be a Position object and building should be a character(Global const variable) representing the building type.

  ** This string is a command that you should put in your command list and send with send_cmd **

  example: game.build((5, 8), BLD_GOLD_MINE) will build a gold mine on (5, 8) under the condition that you already occupied (5, 8) and you have enough gold to build the gold mine.

• .upgrade(position)

  Returns a string for upgrade the build on position. position should be a Position object.

  ** This string is a command that you should put in your command list and send with send_cmd **

  example: game.upgrade((5, 8)) will upgrade the building on (5, 8) under the condition that you have a building on (5, 8) and it can be upgraded.

• .send_cmd(cmd_list)

  Sends the command list to the server. If you send multiple command lists to the server in a single round, the latter one will overlap the former ones. Only the last command list the server receives is valid. In theory, you should only send one command list every round.

  Returns a dict from the server of whether the command is taken. {"success": <boolean>, "err_msg": <str>}. err_msg only exists if success is False.

  All the commands(attack, build, upgrade) above will only return a string representing the command. So * nothing will happen * if you do not send the commands to the server. You should keep a cmd_list and do something like cmd_list.append(game.attack((1, 1), 250)) and cmd_list.append(game.build((2, 5), BLD_ENERGY_WELL)) Then do a game.send_cmd(cmd_list)

User

attributes of User

  Current energy the user has.

  Height of the game map

methods of GameMap

• game_map[position] (game_map.get_cell(position) in Java)

  Get the MapCell object on position. position should be a Position object or a tuple (x, y).

  example: game_map[(1, 2)] will get you the MapCell object of (1, 2), which is equivalent to game_map[Position(1, 2)]

MapCell
