Abstract

To prevent a network response to a game server from deteriorating, a flag information management unit of a game server is provided. The flag information management unit manages flags indicating information on player characters (PC) in response to requests from client systems (or communication terminals)s occurring during network game progress. A flag information transmission unit transmits only the information linked to the managed flags to the client systems (or communication terminals). Then, on the sides of the client systems (or communication terminals), a control unit controls a CD-ROM drive in accordance with the information, and the necessary information is reproduced from a CD-ROM.

Claims

1. A network game system comprising:

the game server system comprising;

a client management system that manages the client systems by identifying the client systems individually based upon the client information added to requests sent from the client systems via the network, the client information indicating which client system sent the request;

a flag information management system that manages flags indicating the character information in response to the requests from the client systems occurring during the game progress, the flags being associated with the client information for each of the identified client systems;

a flag information transmitter that transmits only the character information associated with the flags, to the identified client systems;

a communication interface that receives the requests from the client systems; and

a storage that stores a flag table, comprising the flags associated with a plurality of characters in association with the client information for each of the identified client systems, and

the client system comprising;

a request generator that generates a variety of requests according to the game progress; and

a controller that controls display action based on the character information associated with the flags.

2. A game server system for providing a network game environment, comprising:

a client management system that manages client systems by identifying the client systems individually based upon client information added to requests sent from the client systems via the network the client information indicating which client system sent the request;

a flag information management system that manages flags indicating character information in response to the requests from the client systems occurring during the game progress, the flags being associated with the client information on each of the identified client systems;

a flag information transmitter that transmits only the character information associated with the flags, to the identified client systems;

a communication interface that receives the requests from the client systems; and

a storage that stores a flag table, comprising flags associated with a plurality of characters, in association with the client information for each of the identified client systems.

3. The game server system according to claim 2, wherein the flag information management system manages the character information on each of the client systems, by setting, in the flag table, the flags corresponding to each of the characters in response to the requests from the client systems, the flags being associated with the client information, and by transmitting the character information associated with the flag and clearing the flag corresponding to the transmitted character information.

4. The game server system according to claim 2, wherein the flag information management system executes:

a deletion transmission processing that identifies the flags indicating which character is displayed based upon the flag table, judges whether there is a character that is not within a predetermined distance from a certain character, and, when it is judged that the character is not within the predetermined distance, transmits information associated with a deletion flag so as to clear the deletion flag; and

a new transmission processing that identifies a position of one character with respect to another character in an arbitrary field, obtained by dividing an area where the characters can move into a plurality of virtual cells, and, when it is judged that the one character is within a predetermined distance from the other character, transmits all of the character information on the judged character to the client system of the certain character and clears all flags other than an active flag.

5. The game server system according claim 2,

wherein the flag information management system manages the flags, when a first character responds to control of a first client system by a first player, by:

setting the flag relating to the first character of at least one piece of the client information when the first character changes states;

setting a display flag defining whether to display a second character on a screen of the first client system based upon a distance from the first character to the second character; and

clearing, when updating the character information, the display flag of the first character of the updated client information.

6. The game server system according to claim 2, wherein the flag is linked to status information of the character in accordance with the game progress.

7. A client system that generates a variety of requests in accordance with network game progress provided by a game server system, comprising:

a request generator that generates the requests in accordance with the network game progress; and

a controller that controls display action based upon information sent from a flag information management system, the information being associated with a flag.

8. A network game processing method for transferring client information and character information in accordance with game progress between a game server system that provides a network game environment and a plurality of client systems connected with the game server system via a network, the method comprising, by using the game server system:

managing the client systems by identifying the client systems individually based upon the client information added to requests sent from the client systems, the client information indicating which client system sent the request;

managing flags indicating the character information in response to the requests from the client systems occurring during the game progress, the flags being associated with the client information for each of the identified client systems;

transmitting only the character information associated with the flags, to the identified client systems;

receiving the requests from the client systems via a communication interface; and

storing a flag table, comprising the flags associated with a plurality of characters, in association with the client information for each of the identified client systems; and

the method further comprising, by using one of the client systems;

generating a variety of requests according to the game; and

controlling display action based upon the character information associated with the flags.

9. The network game processing method according to claim 8, further comprising:

managing the character information on each of the client systems;

setting, in the flag table, the flags corresponding to each of the characters in response to the requests from the client systems, the flag being associated with the client information;

transmitting the character information associated with the flag; and

clearing the flags corresponding to the transmitted character information.

10. The network game processing method according to claim 8, wherein managing flag further comprises:

executing deletion transmission processing that identifies the flags indicating which character is displayed based upon the flag table, judges whether there is a character that is not within a predetermined distance from a certain character, and, when it is judged that the character is not within the predetermined distance, transmits information associated with a deletion flag and clears the deletion flag;

executing new transmission processing that identifies a position of one character with respect to another in an arbitrary field obtained by dividing an area where the characters can move into a plurality of virtual cells, and, when it is judged that the one character is within a predetermined distance from a certain character, transmits all of the character information on the judged character to the client system of the certain character and clears all flags other than an active flag.

11. The network game processing method as set forth in claim 8, wherein managing the flags further comprises, when a first character responds to control of a first client system by a first player:

setting the flag relating to the first character and at least one piece of the client information when the first character changes states;

setting a display flag defining whether to display a second character on a screen of the first client system based upon a distance from the first character to the second character; and

clearing, when updating the character information, the display flag of the first character of the updated client information.

12. The network game processing method according to claim 8, wherein the flag is linked to status information of the character in accordance with the game progress.
