In the above, the same parts or parts having similar functions are designated by the same reference numerals or the same reference numerals followed by the same reference numerals. Reference numerals with alphabetical letters are used, and repeated explanations are omitted.

[0018] In this specification and claims, each term is defined as follows:

[0019] A "game image" is an image that is displayed on a display and indicates the progress of a game. In other words, a game image is a two-dimensional visualization of the virtual space that represents the game world. Specifically, the image is captured by a virtual camera placed at least at one point in the virtual space. A part of the virtual space is displayed as a game image. When the position or orientation of the virtual camera is changed, the game image is updated to reflect the position or orientation of the virtual camera. This is subject to change depending on the situation.

[0020] "Program" means a program that is executed by a processor in a computer having a processor and a memory. A "computer" refers to an instruction or set of instructions executed by a program. For example, a program is executed by a server (or a client) In this case, "computer" refers to the server (or client). When a "program" is executed by distributed processing between a client and a "computer" The term "program" includes both servers and clients. This includes "programs executed on the client" and "programs executed on the client". Similarly, when a program is distributed across multiple servers, a "computer" is a set of multiple The term "program" includes each program executed on each server.

[0021] "Item" refers to, for example, weapons, defenses, and other items used by game characters in the game. The term "item" refers to a tool, gadget, accessory, etc. Also, using an item means that the game character The item can be used while still in possession of it.

[0022] First Embodiment In this embodiment, a game control method according to an embodiment will be described with reference to FIGS. He explains.

[0023] [Communication system configuration] FIG. 1 is a block diagram showing the configuration of a communication system 1000 according to the present embodiment. The communication system 1000 includes a communication device 10, a game server 50, a blockchain network The communication device 10 and the game server 50 are connected to the Internet, The game server 50 is connected to a network NW such as a communication line. 0 and the blockchain network 70.

[0024] The client communication device 10 is, for example, a smartphone, and is connected to a network N The communication device 10 can communicate with other devices by connecting to the W. The present invention is not limited to a mobile phone, but also includes tablet terminals, portable game consoles, and other portable devices that can be held by users. That's good.

[0025] The communication device 10 executes the installed game program to display a plurality of A game in which users can play against each other is provided on a game server 50 and a blockchain network. 70 to provide the user of the communication device 10 with a map that can be moved in the virtual space. The user can control a game character that can be used to fight other game characters. In this way, games in which multiple game characters compete against each other are provided to users. Since the game is a multiplayer game, multiple communication devices 10 are provided, each of which corresponds to a different game character. Connect to the game server 50.

[0026] The game server 50 provides the communication device 10 with an application program. This is an example of an information processing device that provides various services. For example, the login process when playing an online game on the communication device 10, Other services include, for example, SNS (Social Networking Services). In FIG. 1, the game server may include a social networking service. Although the server 50 is illustrated as a single information processing device, it may be comprised of multiple information processing devices. It may be possible.

[0027] The application program includes, for example, an application for executing a game described below. This includes application programs (called game programs). The program is recorded on a recording medium that can be read by the game server 50. The game server 50 may include a storage device connected to the game server 50. Alternatively, the game server 50 may be connected to the storage device via a network NW. It may be a storage device.

[0028] The application program is a decentralized application (Dapps). Dapps can also be used as smart applications. This system uses a mechanism called "blockchain contract" that automatically executes contracts on the blockchain. Dapps are smart contracts that run on blockchains such as Ethereum. A general term for applications that can be realized by using Tract.

[0029] Ethereum is a blockchain that is used to build decentralized applications and smart contracts. Smart contracts are a platform that automatically executes protocols such as contracts. It is implemented in the blockchain to execute. Blockchains such as Ethereum Fungible tokens are tokens that can be issued by the blockchain (Ethereum tokens). and non-fungible tokens Unlike fungible tokens, NFTs are not fungible. NFTs are tokens that do not have their own unique value that is distinct from other NFTs. do.

[0030] The game server 50 cooperates with the blockchain network 70 to distribute in-game items. In the following explanation, the item with the NFT issued will be These are called NFT items or NFT items. NFTs are smart devices that are stored on the blockchain. This is recorded as metadata in the copyright contract and is traceable, so that creators, rights holders, It can verify transaction information including details and history such as ownership information and NFT ID. The issuance of NFTs is realized, for example, through the execution of smart contracts. The items created by users are added to the item database of Server 50. The game server 50 receives NFT requests from users or programs. When it receives an instruction to do so, it generates an NFT ID linked to the item ID and stores it in the item database. It also generates code (bytecode) with metadata including the NFT ID. The blockchain uses zero addresses to send a Token to the blockchain. Receiving input addressed to the address signals the start of a new contract and the NFTI A smart contract containing a code containing D is started. A token is a Since ownership is managed by smart contract, the initiation of a smart contract is the opening of an NFT. The NFTs issued in this way can be used by users on a smart contract. This allows users to transfer NFTed items to their wallet addresses. You can buy and sell your NFTs on the Marketplace, an NFT exchange, or buy and sell other NFTs. Users who have issued NFTs corresponding to items can exchange them for items that they have purchased. The user is called the creator of the NFT item. In addition, the NFT item is sold on the market. Users who purchase and own an NFT item on the Place are called the owners of the NFT item.

[0031] The blockchain network 70 is composed of a first layer 70-1 and a second layer The first layer 70-1 and the second layer 70-2 are composed of two layers. The layer 70-2 is layer 1 (or L1) and layer 2 (or L2). The first layer 70-1 is the backbone of the blockchain network 70. The second layer 70-2 is a blockchain that A supplementary measure to address the scalability issues that arise in the -1 blockchain Currently, there are multiple types of programs in the second layer 70-2. It has been designed to complement the first layer 70-1 in terms of functionality, For example, Ethereum's "Plasma" is It is connected to the Layer 1 blockchain at a different layer (so-called "on-chain") ) type of Layer 2, and the data structure also forms a chain structure. Therefore, in Ethereum, smart contracts are used not only in Layer 1 but also in Layer 2. In this embodiment, the second layer 70-2 It is written on the premise of a Layer 2 similar to Ethereum. However, there are scalability issues. When a large number of transactions are carried out on the blockchain, processing times can be delayed or This refers to the problem of increased fees (so-called gas fees). Second Layer 70-2 The various programs are first layer 70-1 blockchain transactions By processing some of the transactions on behalf of the other users and sending the final results back to the blockchain, This can reduce the burden on Year 70-1.

[0032] As a game control method according to one embodiment of the present invention, a blockchain specialized for games is used. This may be realized in the form of a game-specific blockchain project under consideration. Layer 1 will be the core blockchain for the project, and participants in the project will Each game publisher operates its own Layer 2 system, and the Layer 2 It is a game developer that uses tokens created from smart contracts that can be implemented in For example, the Layer 1 blockchain is a platform on which Each company will open its own store (Layer 2 on-chain system) and use its own currency (Tokens implemented in each Layer 2 of each company) Products (each game title) using It is also possible to realize a business model in which the game publishers Shar uses smart contracts implemented on the Layer 1 blockchain. Games using tokens (virtual currency used in game-specific blockchains) It is also possible to create a blockchain that is specialized for games and uses tokens from each company. It is highly compatible with the virtual currencies used in cryptocurrencies, making exchange costs extremely low. NFT items can be used in games from different game publishers.

The status information may affect a game character operated by the communication device 10 or may be transmitted to other communication devices. It may also affect other game characters operated by the device. For example, defensive power or magical power parameters may be changed. The meter value is a parameter value that affects your game character, and the attack power parameter The parameter values ​​are those that affect other game characters. By using an item or NFT item, the status information of the item can be shared with the user. Or it may affect the status information of a game character. (Parameter value) is information (parameter value) specific to the item ID. NFTID is If the item is NFT, it will be added. The image corresponds to the item. The item setting information change unit 5035 changes the setting information of the item. The status information and image are changed. The items may be stored in the same database, or by item type (weapons, armor, tools, The information may be stored in a different database for each device (such as a device accessory).

[0074] Each of the communication devices 10 acquires or transmits various types of information (hereinafter, referred to as "game information"). The game information is generated and transmitted from the communication device 10 to the game server 50. The game information DB 223 collects the game progress status sent from each of the communication devices 10. The game information includes not only image and sound information related to the game, but also each The character's event progress, position information in the virtual space, and action information are Included.

[0075] FIG. 9 is a diagram for explaining the configuration of the game information DB 223. B223 is a user ID, character name, location information, progress, action, item I D. The position information is the coordinates of the game character in the virtual space. For the sake of explanation, specific locations in the virtual world are shown. Progress is tracked by game events. The progress of the game. The game event that the game character has currently reached. Action indicates the action of the game character. Item ID indicates the item that the game character uses. The ID of the item is stored in the item information DB shown in FIG. The item ID is the item ID of an item that the game character owns.

[0076] The user information DB 221, the item information DB 222, and the game information DB 223 include The FTID and the creator's user ID are not linked. The user ID included in the game information DB 223 is the user ID of the item owner. It is not the creator's user ID. For example, in each information DB, the creator's user ID is Even if the user ID is included in the game, the user ID will only be available in the game in which the item was created. NFT items can be used in other games. This reflects the advantages of NFTs, such as the uniqueness and traceability of data that can be held as assets even if the data is not used. In order to do this, the NFT ID and the creator's user ID are stored in each information DB of the game server 50. Instead of linking the NFT ID to the creator's user ID, the blockchain is used to link the NFT ID to the creator's user ID. It is preferable to link the above.

[0077] Creators of NFT items can use NFT items owned by themselves or their game characters. You can refer to the item and items that have been converted into NFTs in the past as appropriate. The item does not need to be already owned by the creator of the NFT item or its game character. Here, the characters corresponding to the game characters CH1 and CH2 shown in FIG. The following description will be given with reference to the game image GI.

[0078] FIG. 10 is an example of a game image GI in the communication device 10. As shown in FIG. The game image GI contains a list of NFT items created by NFT item creators. In order to display the list of NFT items, the processing execution unit 503 Get the user ID and associate it to the user ID from the blockchain based on the user ID Then, the item information DB 222 is referenced to extract the NFT ID. The communication device 10 may extract information corresponding to the item ID related to the item. Alternatively, a separate database could be prepared that associates user IDs with NFTIDs. Information may be extracted from the database and displayed on the communication device 10. This is a game image GI of the communication device 10 of a user who created "Sword of Light 1". For example, if you select "Light Sword 1" in the list, the next game image GI will show "Light Sword 1" Display detailed information about ".

[0079] Figure 11 shows the user (game character CH1) who created "Sword of Light 1" This is the display screen when you select "." The game image GI shows the item name 41, the Status information 42, NFT information 43, and current owner information 44 are displayed. The image GI displays an image 46 of the item and an image 45 of the current owner. Current Owner Information 44 and the current owner's image 45 are stored in the user information DB 221 according to the public information. In FIG. 10 and FIG. 11, a game image GI is an image of a specific game. Alternatively, it may be an image of a management screen for managing multiple games.

[0080] Owned by users who purchase NFT items directly or indirectly from the creator of the NFT items A list of items owned by the user is shown in FIG. 12. As shown in FIG. 12, the display screen shows A list of the items owned by the user is displayed. Figure 12 shows the results of a user who purchased "Light Sword 1". 12 is a screen of the receiving device 10. In the list of items shown in FIG. The system includes both NFT and non-NFT items. In the item list, for example, if you select "Light Sword 1", the following screen will appear: , display detailed information about "Sword of Light 1".

[0081] FIG. 13 shows a user (game character CH2) who owns “Sword of Light 1” This is the game image GI when you select ". The game image GI shows the item name 41, the item System status information 42, NFT information 43, and creator information 49 are displayed. The main image GI displays an image 46 of the item and an image 47 of the creator. Creator information 49 and the creator's image 47 are stored in the user information DB 221 according to the public information. It will be displayed.

[0082] In this way, for each NFT item Sword of Light, , NFT item owners and buyers can check each other's information.

[0083] [Game image description] FIG. 14 is a diagram showing the configuration of a game image GI in one embodiment. In this embodiment, the mobile terminal is held in one hand (specifically, It is assumed that the display unit 13 of the communication device 10 is held in one hand (right hand) and the game is operated with one hand. A game image GI is displayed on the display unit 13. The operation unit 14 is located in the same area as the display unit 13. A touch sensor is disposed as the touch panel.

[0084] The game character CH1 is a game character operated by a user of the communication device 10. The game character CH2 is a game character operated by a user other than this user. The background image BG is an image that represents the background of the ground, buildings, sky, etc. The game image GI shown in FIG. 14 is a game image of a user who has converted an item SW into an NFT. 10. Game character CH1 creates an item SW and puts the item SW in N This is the character operated by the FT user. Game character CH2 is an NFT The SW items are operated by users who purchase them on the NFT marketplace. Character. Game character CH2 is equipped with (using) an item switch. In addition, by having the game character CH2 equip the item switch, the game image will also , is reflected in game character CH2. Also, game character CH2 uses the item SW By equipping the item, operation data indicating that the item has been used is transmitted from the communication device 10 to the game machine. However, the user who operates the game character CH1 is The game character CH2 will be the game character operated by the owner of the item SW that he has converted into an NFT. The user who controls game character CH2 is also unaware that he is a character. The game character CH1 is a game character operated by a user who has converted an item SW into an NFT. In this embodiment, the game character CH1 is A case will be described where the player is in the same town as game character CH2 in the virtual space.

[0085] [Game control method explanation] Next, the control process executed by the game progress control function 500 will be described. The game server 50 (game progress control function 500) is a function that controls whether a character uses an NFT item. When item usage information is obtained, the game control function (resonance function) is initiated.

[0086] 15 is a flow chart illustrating a method for controlling a game in one embodiment. 10 displays a game image GI, and displays the game image based on game operation and control data. The game image includes an area (field of view) that is part of the virtual space. It is defined by the viewpoint and viewing direction set in .

[0087] In the communication device 10, an operation of the game character CH2 using an NFT item is detected. Upon receiving the command, the communication device 10 transmits operation data to the game server 50. The operation data includes , and item usage information. The item usage information is, for example, 2. The user ID and the item ID used.

[0088] The game server 50 acquires item usage information in the item usage information acquisition unit 5031. Receive (step S101).

[0089] The item usage status determination unit 5037 determines whether the game character CH2 is using an NFT item. The item usage status determination unit 5037 determines whether the item usage status is in progress or not (step S102). By obtaining operation data for using the NFT item from the communication device 10 every Whether the NFT item owner's game character CH2 is using the NFT item Alternatively, the item usage status determination unit 5037 may determine whether the item usage status is N from the communication device 10. By obtaining operation data to end the use of the FT item, the owner of the NFT item It may be determined whether the owner's character is using an NFT item. For example, ending the use of an NFT item that a character was equipped with means removing the item. This refers to a work.

[0090] When it is determined that the game character CH2 is using an NFT item (step S 102; YES), the extraction unit 5032, in order to identify the creator of the NFT item, Based on the NFT ID associated with the item ID, the blockchain network Extract information registered in the second layer 70-2 of the data storage 70 (step S103 ). Information about the creator of the NFT item is available on the Smart Contract page of the second layer 70-2. The information of the user who created the NFT item from the smart contract is recorded in the Extract.

[0091] The status information acquisition unit 5033 acquires user information (e.g. For example, a game corresponding to the user ID is retrieved from the user information DB 221 based on the user ID. The information of the character CH1 is extracted, and the information of the game character CH1 is stored in the game information DB 223. Obtain status information. Also, based on the user ID information included in the item usage information, The situation information of the game character CH2 is obtained from the user information DB 221 and the game information DB 223. The information is acquired (step S104).

[0092] The comparison unit 5034 compares the situation information of the game character CH1 with that of the game character CH2. The situation information is compared with the situation information (step S105). Position information within the game, game event progress, action information, character status In FIG. 11, the situation information is at least one of game information, game status information, and group information. When comparing the position information of game character CH1 with the position information of game character CH2 This article explains:

[0093] The comparison unit 5034 judges whether the compared situation information satisfies a predetermined condition (step When using position information in a virtual space as situation information, the specified conditions are For example, the position information of the game character CH1 and the position information of the game character CH2 are In this example, the game character CH1 is determined to be within a predetermined distance. When the position information of the game character CH1 and the position information of the game character CH2 are within a predetermined distance, In step S105, it is determined that the condition is satisfied. and the situation information of the game character CH2 do not satisfy a predetermined condition. If the determination is affirmative (step S105; NO), the process returns to step S101. Execute step 1.

[0094] When the comparison unit 5034 determines that the predetermined condition is satisfied (step S106; YES), The item setting information change unit 5035 changes the status of the item in the item information DB 222. The display mode of the information or game image is changed (step S107). If it is determined that a certain condition is met, the item status stored in the item information DB is In the information, a given parameter value is added or subtracted from the item-specific parameter value. Alternatively, the display mode of the game image may be changed for the image of the item SW. For example, an effect may be added to the image of the item SW. There is no particular restriction on the type of effect. As information, in the item status information, the item-specific parameter value is set to a predetermined When adding an effect to the image of the item SW by adding the parameter value of I will explain this in more detail.

[0095] The item setting information execution unit 5036 is configured to execute the setting information for the game character CH2 using the NFT item. That is, the control data transmission unit executes control for using the The item setting information is output as control data to the communication device 10. That is, A communication device 10 that controls a game character CH1 and a communication device 11 that controls a game character CH2 The setting information of the item is transmitted to the communication device 10.

[0096] FIG. 16 is an example of a game image GI in the communication device 10. In FIG. A user who has converted the NFT of Sword of Light No. 1 can select Sword of Light No. 1 from the list of items that they have previously converted into NFTs. 11 and the display screen shown in FIG. When comparing with the item status information 42 shown in 6, the item setting information has been changed. Specifically, 20 is added to the attack power's unique parameter value of 100, and 10 is added to the unique parameter value of 100. When comparing the image 46 of the item SW shown in FIG. 16 with the image 46 of the item SW shown in FIG. A glowing effect 48 has been added to the W image.

[0097] FIG. 17 is an example of a game image GI in the communication device 10. In FIG. The table below shows what happens when a user who owns "Sword of Light 1" selects Sword of Light 1 from the list of items they own. 13 and the item status information 42 shown in FIG. Comparing with the status information 42, the item setting information has been changed. For every 100 attack power's unique parameter value, 20 is added, and for every 100 magic power's unique parameter value, 10 is added to 100. Also, the image 46 of the item SW shown in FIG. 17, the image 46 of the item SW is compared with the image 47 of the item SW. 48 effects have been added.

[0098] FIG. 18 is a diagram showing the configuration of a game image GI in one embodiment. The home image GI corresponds to the communication device 10 of the user who has converted the item SW into an NFT. As shown in FIG. 1, in the game image GI, the game character CH2 is equipped with ) The image of the item SW has a glowing effect added. This makes the game The user who controls the character CH1 is the game character CH2, which he / she previously owned as an NFT. You can notice that you have the item SW that has been transformed. In the communication device 10 of the user who owns SW, the game character is displayed in the game image GI. Effects will be added to the images of items SW owned by Rakuta CH2. The user who operates the game character CH2 is the game character corresponding to the creator of the item SW. The player can recognize that the character CH1 is nearby in the virtual space.

[0099] After executing the process of step S108, the process returns to step S101. Execute process 01.

[0100] If the item is not in use (step S102; No), the item information DB2 In step S107, the item setting information of 22 is initialized. If it has been changed, it will be restored to its previous state. In other words, the parameter that was added or subtracted Also, delete the effect added to the image of the item SW. If the setting information of the item has not been changed, it is in the initial state. The Noh performance ends.

[0101] Previously, when ownership of an NFT item was transferred, it took time for it to be reflected on the blockchain. Processing times were delayed and gas costs were increasing (scalability issues). It took a while for NTF items to be available in the game. Layer 2 Blocks By using the chain, it is possible to partially replace the transactions of the Layer 1 blockchain. By processing the data in a timely manner and sending the final result back to the Layer 1 blockchain, the processing speed is improved. This allows the Layer 2 blockchain to be used at a lower cost and reduces gas costs. The chain allows the transfer of ownership of NFT items to be reflected without any time lag. As a result, the range of games using NFTs has expanded. New game controls that effectively utilize the uniqueness and traceability of item data are required. Examples of information that utilizes the uniqueness and traceability of data in NFT items include For example, there is information about the creator and owner of an NFT item.

[0102] According to a game control method of an embodiment of the present invention, a suitable game for an NFT item is By using this system control method, new value can be provided. For example, Using the relationship between the user who converted the NFT and the user who purchased the NFT item and change at least one of the performance and display of NFT items in real time within the game. This allows you to temporarily change the performance of NFT items in the game. Also, the display of items in the game space can be improved or reduced. The change allows the creator and current owner of an NFT item to identify each other. In this way, NFT items are not just valuable as circulating goods, but also have value as creators and owners. Association with the person can provide new value to an NFT item.

[0103] <Modification> Although one embodiment has been described above, the embodiment can be modified in various forms as follows. In addition, there is no contradiction between the above-described embodiment and the modified example described below. Unless otherwise specified, they may be combined with each other. It is possible to add, remove, or replace parts of a configuration with other configurations.

[0104] (1) In this embodiment, the position information of the game character CH1 in the virtual space and When comparing with the position information of the character CH2, the predetermined condition is not particularly limited. In the example shown in FIG. 034, the position information of the game character CH1 is set to a predetermined value in accordance with a predetermined condition. (For example, a town, a dungeon, etc.) or not. 034 indicates that the position information of the game character CH1 is located in a predetermined field, and and the position information of the game character CH1 is located in a predetermined field. Alternatively, the comparison unit 5034 may determine whether the game character CH1 and the game Character CH1 and character CH2 are located in the same field and are within a certain distance. It may be determined whether or not the number of the first and second counters is satisfied.

[0105] (2) In this embodiment, the position information of the game character CH1 and the position information of the game character CH2 We have explained an example of comparing using the location information of the The comparison unit 5034 compares the progress of the game event as the situation information. When comparing using situations, the game between game character CH1 and game character CH2 For example, the comparison unit 5034 may determine whether or not the game has been completed based on the degree of completion of an event in the game. Game character CH1 has reached a certain event, and game character CH2 has reached the certain event. If the vent has been reached, it may be determined that the predetermined condition is satisfied. When either game character CH1 or game character CH2 is involved in a given event, If the predetermined condition is met, it may be determined that the predetermined condition is met.

[0106] The item setting information change unit 5035 compares the progress of the event and changes the item setting information. When changing the information, the item setting information change unit 5035 changes the item status information. Depending on the progress of the game event, the parameter value of the item may change. For example, the item setting information change unit 503 may execute a process of increasing or decreasing the value. 5: Increase the parameter value according to the achievement of the game event of game character CH1. Alternatively, a process of subtracting a parameter value may be performed. The item setting information change unit 5035 changes the game event setting information according to the achievement level of the game character CH2. In response, a process of increasing the parameter value or a process of subtracting the parameter value may be performed. may be executed.

[0107] When the item setting information change unit 5035 changes the setting information of an item, In the status information, depending on the progress of the game event of game character CH1, A process for changing the display mode of the NFT item in the game image may be executed. For example, Effects that change depending on the progress of game events for game character CH1 The types may be different.

[0108] (3) When the comparison unit 5034 compares the action information as the situation information, The action information of the game character CH1 and the action information of the game character CH2 are The comparison unit 5034 may also determine whether the game character CH It may be possible to determine whether game character CH1 or game character CH2 is performing a specific action. For example, the comparison unit 5034 detects that the game character CH1 is in combat and If the CH2 is in combat, it may be determined that the predetermined condition is satisfied. 034 indicates that the game character CH1 is moving and the game character CH2 is moving. In some cases, it may be determined that a predetermined condition is met.

[0109] When the item setting information change unit 5035 changes the setting information of an item, In the status information, the action information of the game character is changed according to the action information of the game character. For example, a process for changing the display mode of a game character may be performed. The type of effect to be changed may differ depending on the action information of CH1. .

[0110] (4) The comparison unit 5034 compares the status information of the game character CH1 with the status information of the game character CH2. When comparing the status information of game character CH2, the level, rank, The comparison unit 5034 may determine whether a predetermined condition is satisfied by using the number of medals or the like. When comparing the level of the game character CH1 with the level of the game character CH2, In this case, the level of the game character CH1 exceeds a predetermined value, and If the level of exceeds a predetermined value, it may be determined that the predetermined condition is satisfied. The comparison unit 5034 checks whether the level of the game character CH1 is higher than the level of the game character CH2. If the threshold is higher than the threshold, it may be determined that the predetermined condition is satisfied.

[0111] The item setting information change unit 5035 compares the status information and changes the item setting information. When changing, the item-specific parameter value is changed to Depending on the status information of the character, the parameter value is increased or decreased. For example, the parameters may be changed according to the level or rank of the game character CH1. A process of increasing the parameter value or a process of decreasing the parameter value may be performed. Also, the parameter value increases according to the level or rank of the game character CH2. A process may be performed, or a process of subtracting the parameter value may be performed.

[0112] When the item setting information change unit 5035 changes the setting information of an item, In the status information, the status of the game character is displayed according to the game image. For example, a process for changing the display mode of a game character may be performed. The type of effect that is changed may differ depending on the status information of CH1. .

[0113] (5) The comparison unit 5034 compares, as the situation information, the group information of the game character CH1 and When comparing with the group information of game character CH2, for example, Determine whether the group of H1 is the same as the group of game character CH2. The comparison unit 5034 may compare the group of the game character CH1 and the group of the game character C If the group of H2 is the same as that of H1, it may be determined that the predetermined condition is satisfied. If the group of the game character CH1 is different from the group of the game character CH2, It may be determined that the condition is satisfied.

[0114] The item setting information change unit 5035 compares the group information and changes the item setting information When changing, the group of game character CH1 and the group of game character CH2 The item status information will display the item-specific parameters if the A process may be performed to increment or decrement a predetermined parameter value. The system setting information change unit 5035 changes the group of the game character CH1 and the If the group of the item and the group of the CH2 are the same, the item status information A process of increasing a predetermined parameter value may be performed on the system-specific parameter value. If the group of the game character CH2 is not the same as that of the game character CH3, the game setting information change unit 5035 In the item status information, the item-specific parameter value is set to the specified parameter. Alternatively, a process of subtracting a data value may be performed.

[0115] When changing the setting information of an item, the item setting information change unit 5035 In the status information, the display state of the item in the game image is changed according to the group information. For example, a process of changing the game character CH1 and the game character CH2 may be performed. When the group information of game character CH1 and game character CH2 is the same, When the group information of the two is different, the type of effect to be changed may be different.

[0116] (6) If a predetermined condition is met, the item setting information change unit 5035 changes the status of the item. In the item information, the item-specific parameter value is set to a specific parameter for each item type. For example, the item setting information change unit 5 may execute a process of increasing or decreasing the data value. 035 has different attack power parameter values ​​that are increased or subtracted depending on the type of weapon. Or, the defensive power parameter value that is increased or subtracted may differ depending on the type of armor. It's fine.

[0117] (7) Although a number of predetermined conditions have been exemplified above, In the control function, the comparison unit 5034 checks whether at least one of a plurality of predetermined conditions is satisfied. Therefore, a plurality of predetermined conditions may be appropriately combined. For example, The comparison unit 5034 compares the position information of the game character CH1 and the game character CH2 with a predetermined If the condition is met, and if the status information meets the specified condition, the item setting information The information change unit 5035 may execute a process of changing the setting information of the item. The comparison unit 5034 compares the position information of the game character CH1 and the game character CH2 with a predetermined If the conditions are met and the progress of the game event meets the specified conditions, the item The system setting information changing unit 5035 may execute a process of changing the setting information of an item. The combinations are not limited to those exemplified above, and three or more predetermined conditions may be combined.

[0118] (8) As shown in Figures 10 to 13, the creator of the NFT item and the owner of the NFT item The two can obtain each other's information and display it as a game image GI on the display unit. During the program, the creator of the NFT item will obtain information about the owner of the NFT item. In this case, the communication device 10 selects an NFT item from the NFT item list in FIG.
