JP7474578B2 - GAME PROGRAM, GAME PROCESSING METHOD AND INFORMATION PROCESSING DEVICE - Google Patents

Description

This disclosure relates to a game program, a game processing method, and an information processing device.

There is a known game system that varies parameters set in base game content by combining game content that serves as a combination material with the base game content (see, for example, Patent Document 1).

When a player plays a game, this game system uses the game content acquired by executing an application program capable of executing what is called gacha (registered trademark; the same applies below) for synthesis.

Japanese Patent No. 5204330

In such a game system, each time a synthesis material game content is synthesized with a base game content, the parameters set in the base game content increase, and when the parameters reach a predetermined value, the rank of the base game content increases. Therefore, when a high-ranked base game content is obtained, if there is a synthesis material game content that was previously used to vary the parameters of the base game content, that game content will be wasted.

The present disclosure provides a game program, a game processing method, and an information processing device that can effectively utilize second content that is a synthesis material for first content.

According to one aspect of the present disclosure, a game program is provided that causes a computer to execute the following processes: determining a player's acquisition status of a first content used in a game; varying parameters set for the first content each time a second content that can be combined with the first content is combined with the first content; and returning to the player the second content used to combine the first content or a content corresponding to the second content, depending on the determined player's acquisition status of the first content.

According to one aspect, the second content that is used as a synthesis material for the first content can be effectively utilized.

[Player character development]
Parameters are associated with the characters (hereinafter also referred to as "player characters") operated by the players in the battle game. The parameters of the player characters indicate the growth factors of the player characters, and the synthesis process is executed to train the player characters. Thus, the parameters of the player characters are numerical values indicating the growth of the player characters. The rank of the player characters (for example, the number of stars shown in the display component 103 in FIG. 12) increases when the parameters increase to a predetermined value.

The synthesis process varies the parameters set for the first content each time the second content, which can be synthesized with the first content that is the base game content, is synthesized with the first content. This allows the first content to be developed using the second content.

For example, when a second content is used with a first content, the parameter of the first content increases, and when it reaches a predetermined value, the rank of the first content increases. If the predetermined value is 100, when the parameter of the first content becomes 100 by combining the second content, the rank of the first content increases by one.

In an embodiment, the first content is a player character operated by a player in a battle game. In an embodiment, for each type of character, the player character can only own one unique character. The player character is an example of the first content used in the game. The first content is electronic game data, and is not limited to a player character, and may be other game content, tangible objects in the virtual space such as figures, cards, items, equipment, and virtual medals. The first content may be intangible objects in the virtual space such as skills and abilities.

The player can obtain the first content by executing an application program capable of executing gacha (hereinafter, also referred to as "drawing gacha") while not playing the battle game using the terminal device 30. The first content can also be obtained by methods other than gacha. In the embodiment, a material item is used as an item that changes the parameters of the first content. The material item may be obtained by drawing gacha, during the game, or by other methods. The material item is an example of second content that changes the parameters of the first content. The second content is electronic game data and is not limited to material items, and may be other game content, characters, figures, cards, items, equipment, virtual medals, and other tangible objects in the virtual space. The second content may be intangible objects in the virtual space, such as skills and abilities.

In the synthesis process, each time an acquired material item is synthesized, the parameters set for the player character can be changed based on the numerical value associated with the material item. The numerical value associated with the material item can have various values within a predetermined range. The numerical value associated with the material item can be 1, 2 or more, and is not particularly limited.

In the embodiment, the rank of a player character can be set from 1 to 7, but the rank numerical range is not limited to this. There are two ways to increase the rank of a player character. The "first method" is a method of increasing the rank of a player character by increasing the parameters of the player character to a predetermined value through a synthesis process of material items. The "second method" is a method of increasing the rank of a player character by obtaining a player character with a higher rank than the current rank of the player character through gacha. When the rank of a player character increases, the ability value of the player character is powered up, allowing the player character to play the battle game with an advantage. Examples of the ability value of a player character include the player character's stamina, attack power, defense power, skills, items, etc. However, the ability value of a player character is not limited to these.

For example, the parameter calculation method is to add the numerical value of the material item to the parameter of the player character. For example, if the player character's current parameter is "2" and the numerical value of the material item is "1", the synthesis process will add the numerical value of the material item, and the player character's parameter will change from "2" to "3".

In principle, the player cannot keep the material items that have been used in synthesis. For this reason, if the player character's rank is increased using the second method, and the synthesis process of material items has been performed previously using the first method, the material items used using the first method will be wasted. For example, if the player character's current rank is "3" and the rank of the player character obtained through gacha is "4", the player character's rank will be increased to "4" using the second method. And if x material items (x is a positive integer) were used previously to increase the player character's parameters, and the player character's parameters and/or rank were increased using the first method, the x material items used will be wasted.

Therefore, in the embodiment, a game system 1 is provided that returns the material items used in the previous synthesis process to the player when the player character is ranked up by drawing a gacha and obtaining a player character with a rank equal to or higher than the player character's rank. This avoids the user's disadvantage of the material items being wasted, and allows the material items to be used effectively.

The synthesis process is a process that automatically changes the parameters of the player character (automatic synthesis), but the player can also obtain material items and manually change the parameters of the player character (manual synthesis). In the embodiment, in both automatic and manual synthesis, if a player character with a rank equal to or higher than the rank of the player character is obtained and the player character is ranked up, the material items used are returned to the player.

However, if the player character's rank increases as a result of multiple synthesis processes using multiple material items using the first method, the material items used in the synthesis processes before the rank increase will not be returned.

Returned material items may be used in synthesis or in the battle game. However, once a material item has been used in synthesis, it cannot be used again unless it is returned.

[Server Functionality Configuration]
Next, the functional configuration of the server 10 will be described with reference to Fig. 4. Fig. 4 is a diagram showing the functional configuration of the server 10 according to the embodiment. The server 10 includes a control unit 11, a storage unit 12, and a communication unit 13.

In addition, for example, if the rank of the player character obtained by gacha or the like is higher than the current rank of the player character, the synthesis unit 17 sets the rank of the player character to the rank of the player character obtained by gacha or the like.

The return unit 18 returns to the player the material items used to synthesize the player character or content corresponding to the material items, depending on the player's acquisition status of the determined player character. The content returned to the player may be the material items themselves, or content corresponding to the material items.

The display control unit 19 controls the web page of the game screen to be displayed on the terminal device 30. The web page of the game screen controlled by the display control unit 19 is transmitted to the terminal device 30 by the communication unit 13 and displayed on the display unit 35 of the terminal device 30.

The memory unit 12 stores a player information table 21, a character information table 22, a material item information table 23, and a used item information table 24.

The display unit 35 displays a web page of the game screen generated by the server 10 and received by the communication unit 33 on the screen of the terminal device 30.

[Battle game and content integration]
A brief overview of the battle game provided by the game system 1 of the embodiment and the composition of contents will be described below. The game system 1 provides various games that are played using electronic game cards (virtual cards used in the game, hereinafter simply referred to as "characters") associated with game characters. A player character is a virtual card used in the game when a player plays using a terminal device 30, and is included in the "characters".

In the game system 1 of the embodiment, a player can only own one unique player character per character type. The player can play a battle game using the player character that he or she owns. Specifically, the battle processing unit 15 determines the enemy character that will be the player's opponent, and determines the outcome of a battle between these characters based on various parameters (stamina, attack power, defense power) set for each of the player character and enemy character. If the player wins a battle against an enemy character, the items held by the enemy character and the enemy character itself are given to the player.

In the game system 1 of the embodiment, the player can develop a player character by performing a synthesis process to synthesize material items with the player character that the player owns. The game process and synthesis process of the battle game will be described below with reference to Figs. 10 to 12. Fig. 10 is a flowchart showing the game process according to the embodiment. Fig. 11 is a flowchart showing the synthesis process according to the embodiment. Fig. 12 is an example screen showing the player character and parameters of the embodiment.

The process shown in FIG. 10 is executed when a request for delivery of various information related to the game (such as the game program and game screen) is made from the terminal device 30 to the server 10 and the server 10 starts providing game content to the terminal device 30.

First, the content providing unit 14 of the server 10 executes character provision (step S1). Specifically, the content providing unit 14 provides the player with a selected character based on the character information table 22 shown in FIG. 6. This determines the player character for each terminal device 30. FIG. 12 shows an example in which character P is provided as the player character.

Next, in FIG. 10, the determination unit 16 determines whether or not the synthesis of the assigned player character is set to automatic synthesis based on the automatic synthesis flag (step S3). That is, the determination unit 16 refers to the automatic synthesis flag in the player information table 21 shown in FIG. 5 and determines whether or not the setting is set to "ON". Note that the automatic synthesis flag may always be set to "ON (automatic synthesis)".

If the determination unit 16 determines in step S3 that the automatic synthesis flag is set to "OFF", it determines that automatic synthesis will not be performed and proceeds to "1" in the synthesis process shown in FIG. 11, and then to step S14. The process from step S14 onwards will be described later. Note that if the automatic synthesis flag is set to "OFF", the player can obtain material items and manually change the parameters of the player character (manual synthesis).

If the determination unit 16 determines in step S3 of FIG. 10 that the automatic synthesis flag is set to "ON", the synthesis unit 17 executes synthesis processing (step S5). Details of the synthesis processing shown in step S5 of FIG. 10 will be specifically described below with reference to FIG. 11.

In FIG. 11, the synthesis unit 17 changes the parameters of the player character based on the acquired material item (step S11). If the player character's current parameters are "99", its rank is "1", and the value of the acquired material item is "1", the synthesis unit 17 uses the acquired material item to change the player character's parameters from "99" to "100". Next, the determination unit 16 determines whether the player character's parameters are equal to or greater than a preset value (step S12).

When the determination unit 16 determines that the parameter of the player character is equal to or greater than the predetermined value, the synthesis unit 17 increases the rank of the player character by 1 and subtracts 100 from the current parameter (step S13). For example, when the predetermined value is "100", when the parameter of the player character becomes 100, the rank of the player character increases by one and subtracts 100 from the parameter of the player character. For example, the synthesis unit 17 increases the rank of the player character from "1" to "2" and subtracts 100 from the current parameter of the player character. As a result, as shown in FIG. 12, the number of black stars shown in the display component 103 is changed to "2". As a result, the values of the physical strength, attack power, and defense power shown in the display component 104 also increase in response to the change in rank to "2". In step S12, when the determination unit 16 determines that the parameter of the player character is less than the predetermined value, the process proceeds to step S14.

Next, the determination unit 16 determines the acquisition status of the player character (step S14). If the determination unit 16 determines from the acquisition status of the player character that a player character with a rank higher than the current rank has been acquired, the process proceeds to step S15. Note that if the parameter of the player character is determined to be less than a predetermined value in step S12, or if the determination unit 16 determines that a player character with a rank higher than the current rank has not been acquired in step S14, the process immediately proceeds to step S18. In step S18, the control unit 11 updates each table information and ends this process. For example, the values of vitality, attack power, and defense power corresponding to the character information "character P" in the character information table 22 of FIG. 6 are updated. In addition, information on the material item used this time is stored in the used material item corresponding to "character P" in the used item information table 24 of FIG. 8.

If the process proceeds to step S15, the synthesis unit 17 raises the rank of the character to the rank of the acquired player character. For example, if the rank of the acquired player character is "4", the rank of the player character is raised from "2" to "4".

Next, in step S16, the return unit 18 searches the used item information table 24 to obtain the used material items and the number of items used in the previous synthesis process (step S16).

Next, the return unit 18 performs a process of returning the acquired used material items in the number used (step S17). Next, the control unit 11 updates each table information (step S18) and ends this process. For example, the values of stamina, attack power, and defense power corresponding to the character information "character P" in the character information table 22 of FIG. 6 are updated. Also, information on the material items used this time is stored in the used material items corresponding to "character P" in the used item information table 24 of FIG. 8. Also, information on the number of material items returned is stored in the material item information corresponding to "character P" in the material item information table 23 of FIG. 7.

After the synthesis process, returning to FIG. 10, the display control unit 19 executes a process of generating screen data (step S7). For example, the display control unit 19 generates screen data showing character P, which is the player character, and parameters of character P, as shown in FIG. 12. The communication unit 13 transmits the generated screen data to the terminal device 30. As a result, the communication unit 33 of the terminal device 30 receives the screen data, and the display unit 35 displays the received screen data. FIG. 12 is an example of a screen displayed by the display unit 35.

In the example of FIG. 12, display component 101 is an image of the player character. Display component 102 displays the name of the player character, "Character P." Display component 103 displays the "Rank" of "Character P." Display component 103 displays seven stars, and the rank is indicated by the number of black stars among them. The rank of the player character in FIG. 12 is "2." Display component 104 displays the values of each parameter of stamina, attack power, and defense power when the player character's rank is "2." Note that the parameters and rank of the player character shown by display component 103 change depending on the content synthesis process.

With this, if you acquire a player character with a higher rank than your current rank and increase the rank of your player character, the material items previously used to synthesize that player character will be returned. This prevents the waste of material items used to synthesize player characters, and allows you to make effective use of the material items.

The returned material items have a value of a predetermined return rate relative to the material items used in the synthesis. For example, the returned material items may be returned at a return rate other than 100%, such as 110% or 90% instead of 100%. When changing the return rate, the return rate may be determined taking into consideration the player's game progress (e.g., the player's level and strength, the scenario progress and ranking, etc.). The returned material items can be used as synthesis materials for the next player character. The returned material items can also be used in the battle game, for training the player character, and/or for recovering stamina. The returned material items may also be items corresponding to the material items. The content corresponding to the material items may be content equivalent to the material items in the battle game, and may be content different from the material items.

The game program, game processing method, and information processing device according to the embodiments disclosed herein should be considered in all respects as illustrative and not restrictive. The above-described embodiments can be modified and improved in various forms without departing from the scope and spirit of the appended claims. The matters described in the above-described embodiments can be configured in other ways as long as they are not inconsistent, and can be combined as long as they are not inconsistent.

In the above embodiment, the explanation has been given on the assumption that there is only one player character, but there may be multiple player characters. In other words, the first content, which has as an example a player character, may have multiple first content. For example, by obtaining player character A and player character B, it is possible to create player character A', which is an awakened player character A, by combining player character A with player character B.

Before combining player character A and player character B, player character A used a material item to increase its rank to "7", and player character B used a material item to increase its rank to "7". In this case, it is possible to return the material items used to increase the rank of player character B to "7" that were used in the combination to create player character A' above.
