Code

Refactor some code in init_game()

Browse Source 
Move parts of the code out of init_game() to internal functions
ask_number_players(), ask_game_number() and ask_player_names().  Also
move comments out to game.h as appropriate.

what their names are. If needed, instructions on how to play the game
are also displayed.

Parameters: (none)
Returns: (nothing)
This function initialises all game variables and structures, either by
creating a new game or by loading an old one from disk. In particular,
if a new game is to be created, it asks how many people will play, and
what their names are. If needed, instructions on how to play the game
are also displayed.
On entry to this function, the global variable game_num determines
whether an old game is loaded (if possible). If option_max_turn
contains a non-zero value, it is used to initialise max_turn.
On exit, all global variables in globals.h are initialised, apart from
game_move[] (and the previously-set option_XXX variables). If the user
aborts entering the necessary information, abort_game is set to true.

Function: end_game - Finish playing the current game
Parameters: (none)
Returns: (nothing)
This function displays every player's status before declaring the
winner of the game. Note that turn_number is used instead of max_turns
as select_moves() may terminate the game earlier.

Function: show_map - Display the galaxy map on the screen
Parameters: closewin - Wait for user, then close window if true
Returns: (nothing)
This function displays the galaxy map on the screen, using the global
variable galaxy_map[][] to do so. If closewin is true, a prompt is
shown for the user to press any key; the map window is then closed. If
closewin is false, no prompt is shown, wrefresh() is NOT called and the
text window must be closed by the caller.

Function: show_status - Display the player's status
Parameters: num - Player number (0 to number_players - 1)
Returns: (nothing)
This function displays the financial status of the player num, using
the global variable player[num] to do so. The show status window is
closed before returning from this function.

Function: total_value - Calculate a player's total financial worth
Parameters: num - Player number (0 to number_players - 1)

This function calculates the total financial value (worth) of the
player num, using the global variables player[num] and company[] to do
so.
