Function: init_game - Initialise a new game or load an old one
|
||||
Arguments: (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 "game_num" global variable determines
|
||||
whether an old game is loaded (if possible). On exit, all global
|
||||
variables in globals.h are initialised, apart from game_move[].
