Game machine, game program and storage medium having program therein

A computer-readable non-transitory storage medium for getting a computer to play a predetermined game individually or in cooperation with two or more computers that are connected with each other so as to communicate therebetween:

• said computer-readable non-transitory storage medium for making said computer to function as following means:
• virtual world producing means, for producing a virtual world for a game in a virtual space in a memory, space time parameter which is comprised of a world coordinate and a world time being set in said virtual world;
• scenario advancing means, for advancing a scenario by moving a player character operable by a player in response to a signal from input means in said virtual world;
• said scenario advancing means having standalone execution means and cooperation game execution means, said standalone execution means, for executing a standalone game where said scenario of said game is advanced alone by said computer, and said cooperation game execution means, for executing a cooperation game where said scenario of said game is advanced in cooperation with one's own computer and the other computer connected with said one's own computer so as to communicate with each other by exchanging game information between said computer and said other computer through mutual communication;
• memory means, for storing a coordinate position of said player character in said virtual space and a virtual time at this point of time as present information;
• present position renewal means, for computing said coordinate position of said player character in said virtual space during execution of said cooperation game and renewing said present information of said player character stored in said memory means;
• character position transmitting means, for transmitting said coordinate position of said player character in said virtual space during execution of said cooperation game to the other computer which executes said cooperation game;
• 1) in a case where said computer is a host computer which requests the other guest computer to execute said cooperation game at a time of execution of said cooperation game by said cooperation game execution means, said computer-readable non-transitory storage medium further making said host computer to function as following means:
• request input means, through which an instruction to request said other computer to execute said cooperation game is inputted;
• cooperation request information producing and transmitting means, for producing cooperation request information based on said inputted instruction to request to execute said cooperation game and transmitting said information to two or more other game machines connected so as to communicate;
• present information reading and transmitting means, for reading said coordinate position of said player character and said virtual time stored in said memory means at a first point of time when receiving cooperation game acceptance information showing acceptance of participation in said cooperation game from said other computer and transmitting said read information to said other game machine;
• first cooperation game advance switching means, for storing in a memory information showing that said computer is executing said cooperation game with said other computer from which said cooperation game acceptance information was returned, and switching said computer from the last standalone game execution state into a cooperation game execution state;
• first present time renewal means, for clocking said virtual time during execution of said cooperation game and renewing said present information stored in said memory means;
• present time transmitting means, for transmitting said renewed virtual time to said other computer which is executing said cooperation game;
• 2) in a case where said computer is a guest computer which participates in said cooperation game requested by said other computer at a time of execution of said cooperation game by said cooperation game execution means;
• said computer-readable non-transitory storage medium further making said computer as following means:
• cooperation request information input display means, for receiving said cooperation request information transmitted from said other computer and displaying information showing that said cooperation request information was inputted by said other computer on a display;
• acceptance input means, through which an instruction of acceptance of participation in said cooperation game is inputted in response to said received cooperation request information of said cooperation game;
• cooperation game acceptance information producing and returning means, for producing cooperation game acceptance information based on said inputted instruction of acceptance, and retuning said produced information to said other computer;
• virtual time renewal means, for renewing said present information of said memory means by said virtual time at said first point of time, which was received from said other computer to which said cooperation game acceptance information was transmitted;
• other machine present position renewal means, for storing said coordinate position of said player character of said other computer at said first point of time which is transmitted by said present information reading and transmitting means at a time of execution of said cooperation game, in said memory means as said other machine present information, and renewing said other machine present information based on said coordinate position of said player character of said other computer which is transmitted from character position transmitting means of said other computer during execution of said cooperation game;
• character position setting means, for computing and setting a coordinate position where said player character of said computer should be displayed in said cooperation game based on said coordinate position of said player character of said other computer at said first point of time, and for storing said computed position in said present information in said memory means;
• second cooperation game advance switching means, for storing in said memory information showing that said computer is executing said cooperation game with said other computer to which said cooperation game acceptance information was transmitted, and switching said computer from the last standalone game execution state into said cooperation game execution state;
• and
• second present time renewal means, for renewing said present information stored in said memory means based on said virtual time which is transmitted from said present time transmitting means of said other computer;
• wherein said cooperation game execution means displays both player characters of said host computer and said guest computer which participate in said cooperation game on displays of said computers based on said respective coordinate positions of said present information and said other machine present information, and thereafter said player character of said computer is controlled in its position to be displayed based on said present information and said player character of said other computer is controlled in its position to be displayed based on said other machine present information, and control said virtual time in said cooperation game based on said present information.
