Description

How to provide game items with probability intervention}

An embodiment of the present invention relates to a method for providing an interactive probability intervention item in which a probability of obtaining a random item desired by a user varies according to a user's activity.

With the development of communication networks, various online game services are being provided. In addition, high-spec game programs are being created according to the improvement of graphic technology and performance of game user terminals, and game contents accurately depicting the real world or the virtual world are provided.

Accordingly, users' use of online games is increasing, and game genres are also diversifying. Among the recent games, sports games, role-playing games, and first-person shooter games are in the spotlight as popular online games.

A characteristic of online games is that they can be enjoyed by simultaneously accessing the same game content system as others. You can enjoy the game through cooperation or competition with other people by manipulating characters representing each user on the same game screen.

In online games, you can enjoy content by cooperating with other people on a mission, or competing with other people. In this case, in the online game, it is necessary to provide content that induces a competitive spirit among users. This is because, due to the characteristics of online games, in order to maintain or increase the utilization rate, it is necessary to induce a competitive spirit among users, thereby allowing users to continuously access and play the online game.

Content that induces a competitive spirit among users largely includes the level of the user character, items that can be used to be applied to the user character, and skills implemented by the user character.

Among them, the item may be used in various ways, such as to increase the user's desire to possess the item to make the user more interested in the game, or to adjust the difficulty of the game.

Various items in the game are provided randomly by performing specific missions or quests or performing specific actions during game play, or can be obtained through purchase. When the item is provided at random, the user's desired item is not provided, and thus there is a problem that the user's interest is reduced or the user's dissatisfaction is caused.

The above-described information disclosed in the background technology of the present invention is only for improving the understanding of the background of the present invention, and thus may include information that does not constitute the prior art.

It is an object of the present invention to provide a method for providing an interactive probability intervention item in which a probability of obtaining a random item desired by a user varies according to a user's activity.

A method for providing a probability intervention item according to an embodiment of the present invention includes the steps of generating a variation probability table for a corresponding user when a game is started in a user terminal (S110); Each time the user performs a predetermined favorable interaction in the game, the changed favorable preference data is updated in the change probability table (S120); selecting an item for which the user wants to increase the probability of winning and selecting a gacha start menu (S130); checking the target item information selected by the user in the server (S140); applying a variation probability to the target item according to the user's favorable interaction result (S150); determining the final variation probability of the target item (S160); a step of performing a random drawing to which the final variation probability is applied (S170); and providing a randomly selected item to the user in the random drawing (S180).

The variation probability table is characterized in that it is generated in the server.

The variation probability table may be generated in the user terminal.

The favorable interaction includes conversation with a preset NPC or character, performance of a quest or mission presented by the character or NPC, conversation with the NPC, and viewing of information related to the target item.

It is characterized in that the favorable interaction is accumulated as a favorable feeling score and stored in the fluctuation probability table.

The target item includes a character or an item provided on the game.

The favorability score is set according to the type of the character, and an additional probability according to the increase in the goodwill is provided for each type of relationship network of the character.

The timing of the random drawing for each character type may be determined by the user.

According to an embodiment of the present invention, when a predetermined amount or more of a predetermined interaction is performed with respect to a character or a specific item that the user wants to acquire, the random acquisition probability of the corresponding character or specific item increases, making it easier to obtain the character or item. It works. Accordingly, the user's satisfaction is improved, complaints are reduced, and there is an effect of continuously maintaining the user's interest.

In addition, it is possible to secure the legitimacy of spending in the game by linking the emotional element of the good feeling that the user directly accumulated by interacting with the characters in the game to the product.

In addition, there is an effect of securing the gameplay of the random acquisition system by intervening in the probability of the random acquisition system through the goodwill information.

Hereinafter, a method for providing a probability intervention item according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. Hereinafter, only the configuration for providing the probability intervention item will be described).

In this specification, the term 'item' is defined as a term that includes all game items, game currency, and game characters provided to a user or a user's character within the game.

1 is a block diagram illustrating a system configuration for implementing a method for providing a probability intervention item according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating a method of providing a probability intervention item according to FIG. 1 .

As shown in FIG. 1 , a probabilistic intervention system for implementing a method for providing a probabilistic intervention item according to an embodiment of the present invention may include a server 100 and a user terminal 300 . Although only one user terminal 300 is illustrated in the drawing, a plurality of user terminals 300 may communicate with the server and constitute a probabilistic intervention system.

The server 100 may be a server for operation and update of games installed in the user terminal 300 , or a separate server for probability management. The server 100 may include a game progress unit 110 , an item management unit 120 , a user management unit 130 , and a probability management unit 140 . They are linked to each other to provide items according to the user's activity.

The game progress unit 110 functions to provide a random item according to a change probability linked to a user's activity rather than the overall operation of the game, and functions in conjunction with the item manager 120 and the probability management unit 140 .

The item management unit 120 stores information on various items provided on the game, and when the user selects an item for which a probability change is desired in the game, the selected item information is transmitted to the game progress unit 110 .

The user management unit 130 determines whether the user plays a normal game in the game or interacts for a change in probability, and transmits the determination data to the probability management unit 140 , and the variable probability data transmitted from the probability management unit 140 . is transmitted to the game progress unit 110 .

The probability management unit 140 manages and controls the random acquisition probability of the item, and when it is necessary to change the random acquisition probability of the item by user interaction, the probability management unit 140 changes and manages the corresponding probability. The probability management unit 140 generates, stores, and manages a variation probability table for each user.

A game is installed and executed in the user terminal 300 , and various data related to the game are stored and communicated with the server 100 to transmit various data to the server 100 . The user terminal 300 may operate a game in an online state connected to the server 100 or may operate a game in an offline state in which the connection to the server 100 is released. Game data operated in an offline state may be updated to the server 100 when connected to the server 100 later.

A method of providing a probability intervention item according to the present invention will be briefly described as follows.

As shown in FIG. 2 , when a game is first started in the user terminal 300 (user 1), the probability management unit 140 of the server 100 generates a variation probability table (see FIG. 4 ) for user 1 . (S110). This table is used to store and update favorability data to be accumulated with NPCs in the game later.

Whenever user 1 interacts with NPCs to build favorable feelings, the changed favorability data is updated in the variable probability table through the probability management unit 140 (S120).

If user 1 selects the random acquisition menu, selects an item to increase the probability of winning, and selects the gacha start menu (S130), the selection is transmitted to the user management unit 130 of the server 100, and the data is transmitted to the item It is transmitted to the management unit 120 to check the target item information (S140).

In step S130, even when the user 1 restarts the game after stopping the progress of the game, it is possible to reselect an item that has been previously selected and undergoes a probability change to restart the activity for additional probability change.

Here, the gacha start menu is a menu that starts a random drawing procedure with probability intervention, which will be described later, and is a menu that proceeds with probability intervention, not a menu that provides items at random. In the future, an item random payment menu, etc., is additionally provided in the game so that the user can proceed with a random drawing that provides an actual item at a desired time.

When the item management unit 120 determines the probability change target item, the corresponding data is transmitted to the probability management unit 140 , and the variation probability is applied to the target item selected by the user 1 ( S150 ). The application of the variation probability is repeatedly updated until a preset amount of favorability is accumulated. The probability management unit 140 applies user 1's favorability data, the preference intervention formula stored in advance in the probability management unit 140, the basic probability for each item, the variation probability for each item/type of favorable preference, etc. to apply the final change of the target item selected by user 1 The probability is determined (S160).

When the final variation probability is determined, a random drawing to which the final variation probability is applied is performed (S170), and the randomly selected item is finally provided to user 1 (S180). When the final probability is applied to the target item, the corresponding data is transmitted to the item management unit 120 and the game progress unit 110 , and the randomly selected item is displayed on the game screen on the user terminal 300 through the game progress unit 110 . do.

In the above-described embodiment, the server 100 is provided with the game progress unit 110 , the item management unit 120 , the user management unit 130 , and the probability management unit 140 , respectively, and is implemented in connection with each other as an example. However, for convenience, the server is divided by function, and a separate control element is not provided, and the above-described functions may be controlled and managed in the server 100 in an integrated manner.

In the probabilistic intervention system having the above-described configuration, a preference setting for the probabilistic intervention will be described.

3 is a schematic diagram schematically illustrating an item acquisition process according to FIGS. 1 and 2 . 4 is a table illustrating an example of an item acquisition probability according to a user's degree of acquisition of goodwill.

Hereinafter, 'interaction' means that a user and an in-game character or NPC exchange activities according to a preset rule with each other. For example, as shown in FIG. 3 , the user may perform a quest or mission presented by a character or NPC, talk with the NPC, or view related character information. With respect to such a user's activity, the character or NPC provides a preset good feeling score to the user as shown in FIG. 4 , so that interaction occurs and the user can build good affinity. The accumulation of favorable feelings can be given on a scale from 1 to 100 (a higher number corresponds to a higher favorability score).

Through interaction, users can accumulate favorable feelings and change the probability of obtaining the desired items, and for this purpose, various kinds of favorable feelings systems are set up on the server. Hereinafter, various favorable sensitivity systems will be described with practical examples.

5 to 7 are diagrams illustrating an example of a favorable persona system for providing an item according to the method for providing a probability intervention item of the present invention. The favorable persona system may be stored in a separate storage of the server, or may be stored in the game progress unit 110 or the probability management unit 140 .

As shown in Figures 5 and 6, the types of characters (personas) that are provided in the form of items in the game or that can be obtained through random draws are: can For each of the five types of characters, the favorable score (Y-axis) that can be obtained according to the favorable interaction (X-axis) may be set differently. For example, in the case of an industrious character, a good feeling score may be acquired quickly for a favorable interaction in the second half, and in the case of a goodwill character, a good feeling score may be quickly acquired for a good feeling interaction in the early part. In the case of a dominant character, a favorable preference score may be obtained differently for each type of character, such as obtaining the same favorable affinity score according to favorable interaction from the beginning to the second half.

Such a numerical formula for increasing favorable sensitivity may be set differently for each character as shown in FIG. 7 , and accordingly, the results of FIGS. 5 and 6 may be derived (in the numerical formula for increasing favorable sensitivity in FIG. 7 , x is favorable interaction, n is Sensitivity enhancement variables for each persona (character type), a to z may be defined as favorable sensitivity variables for each character).

Therefore, depending on the type of character that the user wants to acquire, the method of attacking the character varies, such as the user constantly interacting with the character or NPC, or intensively interacting in the early or late stage.

This means that the probability of obtaining the desired character increases when the timing of the random draw is applied differently depending on the type of character. That is, if a character whose favorability increases rapidly in the beginning is selected, it is advantageous to proceed with a random draw after rapidly increasing the favorability by interacting a lot in the beginning because the probability of a random drawing increases. Conversely, if you select a character whose favorability increases rapidly in the second half, it is advantageous to increase the favorability by interacting a lot in the latter half and then proceed with a random draw. However, in the case of a character whose favorability is provided equally irrespective of the time point, it is okay to determine the random drawing time according to the user's situation.

That is, the user may increase the goodwill by interacting with each other according to the type of the character, and the probability of obtaining the desired character may be increased because the probability of a random drawing is changed according to the increase of the goodwill.

As described above, a 'probability intervention' in which the probability of a random drawing varies according to the user's acquisition of favorable feelings may be defined. In the case of random drawing in a general game, the user cannot select the timing of probability intervention, but in the case of the present invention, there is an advantage in that the user can execute random drawing with probability intervention at a desired time.

Meanwhile, the above-described favorable persona system is an example of interaction related to one character, and interactions with several characters may occur in the game.

8 to 12 are diagrams illustrating an example of a network goodwill system for providing an item according to the method for providing a probability intervention item of the present invention.

8 to 12 , when the character A and the character B exist, the character A and the character B may form a relationship such as a lover, a friend, a colleague, a hatred, or the like. The good feeling transmitted to the above-mentioned relational network corresponds to the value of x in the good feeling persona value of character A.

Here, the character A may be a character with which a direct favorable interaction with the user occurs, and the character B may be a target that has an indirect influence. All figures are in %, 0% can be defined as the lowest favorability, and 100% as the highest favorability (meaning the good feeling between the character and the user).

For example, as shown in FIG. 8 , when the favorable sensitivity between the character A and the user is 30% or less, the favorable sensitivity of the character B may be set to increase together by 1/2 of the increase in the favorable sensitivity of the character A. However, if the favorable sensitivity between the character A and the user is 50% or less, the favorable sensitivity of the character B may be set to decrease by 1/2 of the increase in the favorable sensitivity of the character A. In addition, if the affinity between character A and the user is 100%, the affinity with the user is too high, so that the romantic relationship between character A and character B is canceled and, as a side effect of breaking the romantic relationship, the favorability of all characters except for character A is reduced. can be set.

9 to 12 also may be set in various ways so that the goodwill with the character B or other characters is different according to the increase in the goodwill of the character A according to various relational networks between the characters A and B in the same way.

With this setting, the network of relationships such as lovers, friends, colleagues, hate, and hatred has the effect of realizing a network between human groups in the game, and has the effect of intuitively and visually applying real human relationships in the game.

The goodwill and character acquisition probability intervention described in the present invention can be set as follows.

The additional probability that can be obtained through favorability can be set in various ways through various formulas. The purpose of giving additional probabilities is to induce users to adjust the timing of probabilistic intervention through favorable interaction according to various formulas. The additional probability obtained through the increase in the likeability may be set to be applied up to 50%.

13 to 15 are graphs showing the correlation between the good feeling and the probability (in the equations according to FIGS. 13 to 15, Y is the final probability, H is the basic probability of the character, and X and x are the good feeling).

As shown in FIG. 13 , the 'intuitive intervention type' model in which the likeability intuitively intervenes in the probability is a model in which the additional probability that can be additionally obtained is also linearly increased up to 50% as the favorability score increases. In the case of the intuitive intervention model of FIG. 13 , a graph of additional acquisition probability (y-axis) for each favorable score (x-axis) may be derived by the following equation.

The intuitive intervention type also has the effect of conveying the effect of obtaining additional probability to users visually and intuitively, as the additional probability increases as the favorability score increases, and it has the effect of easily conveying the reason (justification) to attack the good feeling to the user.

As shown in FIG. 14 , the 'late-stage' model is a model designed to acquire more additional probabilities as a higher affinity is accumulated. The latter model can induce a favorable impression by using the reward psychology of users by applying it to the character who must proceed to the end. In the case of the latter model, a graph of additional acquisition probability (y-axis) for each favorable score (x-axis) can be derived by the following equation.

As shown in FIG. 15 , the 'early-type' model designed to quickly obtain additional probabilities in the early stage of earning goodwill is an efficient model with low favorable sensitivity. The early model is a model designed so that the user can target the character in a short time by applying it to consumable characters or extra characters that do not need to fill up to 100 in favorability attack.

In the case of the early model, a graph of additional acquisition probability (y-axis) for each favorable score (x-axis) can be derived by the following equation.

The aforementioned intuitive intervention type, late type, and early type models can be applied to suit the characteristics of various characters in the game and used to provide additional probability according to the interaction for obtaining favorable feelings.

Meanwhile, in the probabilistic intervention system for implementing the above-described probabilistic intervention item providing method, the system may be configured such that generation of a user table, update of favorable sensitivity data, and probability management are performed in the user terminal rather than the server (as described above). A detailed description of the same configuration as in the embodiment will be omitted).
