For example, if you kill an enemy, your vitality will increase by 5 points and your attack power will increase by 1 point.
[0026]
The pleasure of network games is to increase the ability value of one's character by defeating enemies in cooperation with other players. When the ability value fluctuates, the character data is updated as needed, and the character data on the memory 12 is stored in the character data storage unit 50 of the storage device 14 at regular intervals as the CPU 8 measures time. Thus, even if the player is forcibly disconnected from the net game due to a network trouble or the like, the next game can be replayed from the data immediately before the trouble.
[0027]
In a network game, if many users gather in one world, the game progress is hindered. Therefore, usually a plurality of worlds are prepared, and a game server is prepared for each of them to play a network game.
[0028]
The situation of the network game world is constantly changing by many users participating in the world. The time on the network game is managed by the server device 2, and the time during the game progresses at a time rate different from the real time. The game situation data (see FIG. 16) placed on the memory 12 changes during the game, and the data is stored in the game situation data storage unit 52 of the storage device 14 at regular intervals.
[0029]
As shown in FIG. 7, the electronic commerce unit 26 includes a product data storage unit 54 that stores product data, a product display unit 56 that displays products on the web, and a settlement unit 58 that performs settlement of product consideration. Contains. The product display means 56 stores data to be displayed on the display unit 6-2 of the terminal device 6 connected via the network, such as a built-in display for a mobile phone or an external monitor for a personal computer or the like. It is for displaying.
[0030]
In addition, when the payment means 58 is configured to include a point giving means 62 described later, it also plays a role of giving points simultaneously with the payment.
[0031]
In the electronic commerce means 26 of the present embodiment, the sales merchandise setting means 28 reads the data in the game data storage means 30 in which the game data that changes with the progress of the game by the network game means 24 is stored by the instruction of the CPU 8. The product that can be purchased by the user is set by the procedure of the flowchart shown in FIG.
[0032]
Thus, for example, if the player is “Musashi” in the data shown in FIG. 15, the occupation is a martial artist. Therefore, the “martial arts arrival” which is a martial artist in the character condition in the product list shown in FIG. 17. Etc. can be purchased.
[0033]
Next, a product selection procedure will be described in detail using the flowchart of FIG.
[0034]
When the product selection procedure starts (100), it is determined whether or not the user ID authentication is OK (102). If the determination (102) is NO, the end is set (120). If the determination (102) is YES, the product data is acquired from the product data storage means 54 (104), the game data of the user is acquired from the game data storage means 30 (106), and the product data and the game data are compared. Then, it is checked whether or not the product can be sold (108), and it is determined whether or not the product can be sold (110).
[0035]
If this determination (110) is YES, the product data is picked up in the sellable list (112), the price is set (114), and the presence or absence of the product is determined (116). If this determination (110) is NO, the presence / absence of a product is determined (116).
[0036]
If this determination (116) is YES, the process returns to the check (108) on whether or not the product can be sold. If this determination (116) is NO, the products that can be sold are displayed (118) and the end (120).
[0037]
Thus, the network game requires an ID for participating in the game (see FIG. 14). In the network game, the user is managed by the ID and data processing is performed. The electronic commerce department also uses the common ID to acquire network game data and display a product that can be purchased based on the data.
[0038]
FIG. 15 shows character data operated by the user. The owner ID is an ID assigned to the user when participating in the network game, and the character is managed by the user ID during the game. Occupation is a role played in a network game, and belongs to the Oda family as a power to compete for victory in the game. In the network game, a plurality of powers fight each other, and the user's character belongs to one of the powers to increase the power. In addition, when a townsperson or the like is selected as a profession, it is possible to become unaffiliated.
[0039]
FIG. 16 shows data indicating the game situation. The game status data storage unit 52 of the storage device 14 stores data such as the date of the current game, the number of players participating in the game, the power percentage of each power, and the like. Each data changes with it.
[0040]
Some products (see FIG. 17) that can be purchased by the electronic commerce means 26 can be purchased depending on the state of power in the game by the power judgment means 38. For example, in the case of “Nanban Castella”, it is displayed on the display unit 6-2 of the terminal device 6 through the network as a product that can be purchased when the power of the Oda family is 30 or more. Due to changes in the situation during the game, products that can be purchased through electronic commerce are constantly changing, so that the user can perform electronic commerce more interested than in ordinary electronic commerce.
[0041]
FIG. 17 is an example of a product for electronic commerce. Each product has a condition for the product associated with the network game and displayed at the time of electronic commerce for each user. The character condition is data that cannot be purchased unless the occupation on the game matches. A product whose character condition is a martial artist cannot be purchased unless the occupation is a martial artist. In addition to occupations, products that can be purchased can be limited by character data such as strength and game situation data such as power.
[0042]
A standard selling price is set for the product, but the price can be increased or decreased according to the ability value or data of the user's character to be purchased. For example, in the case of “original wooden sword”, the standard selling price is set to 2000 yen, but the price may be reduced by the amount of the arm of the user character data × 10. In that case, when the arm strength is 30, the discount is 300 yen. Since the player of a game can purchase goods cheaply if the ability value of a character is raised, it becomes possible to play a game with more interest.
[0043]
Next, a configuration in which the chat unit 36 is added will be described. Chat is for enjoying a simple conversation between users participating in a network game, and is one of the enjoyments of a network game. Chat is performed by the chat means 36 receiving the input of the input device 6-1 of the terminal device 6 through the communication means 32 and drawing the display of the chat screen of the display unit 6-2.
[0044]
The chat means 36 stores the use time for each user in the chat time storage means 46 of the game data storage means 30. The sales commodity setting means 28 sets a commodity that can be sold based on the chat time of the user.
[0045]
Next, a configuration in which the party game time storage means 48 is added will be described. Party play is a group of several users who have participated in a network game and take action for a specific purpose. For example, it is the destruction of an enemy character monster during a game, Or search. Even an enemy character monster that cannot be destroyed by the player character alone can be destroyed by cooperation of a plurality of players.
[0046]
The enemy character monster appears when parameters such as attack power and vitality are stored in advance in the network game storage device 14 and the player character reaches the coordinates where the enemy character monster exists on the game. When the player character attacks the enemy character monster and the opponent's physical strength becomes 0, the player character has defeated the enemy character monster. Further, the player character becomes inoperable when the physical strength set by being attacked by the enemy character monster becomes zero. If the player character becomes unable to act, the game ends or waits until physical strength is recovered.
[0047]
To determine whether or not a party game is being played, data indicating that a party game is being played is prepared in the game data, the time in that state is counted until the party play is completed, and the save data storage unit 60 of the storage device 14 is counted. To remember. The sales merchandise setting means 28 sets a sellable merchandise according to the stored party game time.
[0048]
Next, the configuration of the server device 2 including point processing means will be described. FIG. 4 is a block diagram of the server device 2 including point processing means in electronic commerce. The server device 2 includes point granting means 62 for giving predetermined points according to the purchase amount when a product is purchased, and point storage means 64 for storing the points.
[0049]
The given points can be used as a part of the consideration at the time of purchase in the electronic commerce means 26 or a part of the consideration for item purchase in the network game. Further, in the electronic commerce means 26, the granted point rate varies according to the contents of the user game data.
[0050]
The procedure for giving points will be described with reference to the flowchart of FIG.
[0051]
When the point giving procedure starts (200), it is determined whether or not the user ID authentication is OK (202). If the determination (202) is NO, the end is set (212). If the determination (202) is YES, the user's game data is acquired from the game data storage means 30 (204), the discount points according to the user's game data are presented (206), and it is determined whether or not to purchase. (208).
[0052]
If this determination (208) is YES, points are given to the user (210) and the end is set (212). If this determination (208) is NO, the process is ended (212).
[0053]
As described above, in the electronic commerce means 26, the granted point rate varies according to the contents of the user game data. Moreover, in electronic commerce, you may set so that the price of goods of an electronic commerce site may be made cheap, or a point grant rate may be raised, so that the capability value of a player character is high.
