The present invention relates to an online role-playing game (RPG) service, and more particularly, to a role-playing game service in which a plurality of game characters play a role in a virtual game environment. More specifically, a non-playing charater (NPC) controlled by a game service system is manipulated and controlled according to an NPC role command input from a user terminal, thereby assisting the user's game play in a virtual game environment. Characterized in that it can perform a role.

The online role playing game for a plurality of users is a game in which a plurality of users play each other's roles in a virtual space by accessing a server online instead of enjoying each user on their own computer alone. The user can create a singular or plural number of his or her virtual characters in the virtual space, and these virtual characters perform certain actions, so that their scores (or stats) and / or possessions of the virtual characters (items, virtual Increase money) These scores can include many different kinds of stats, what stats are defined, and how certain stats increase by what actions are different for each game. For example, the stats may be determined by the amount and quality of the characters' experience in the game.

In the virtual game environment, not only the characters created by the users as described above, but also non-playing characters (NPCs) provided by the game service system. In general, the NPC means, for example, a 'monster' that users must kill to increase their scores and fight against the user, or a merchant character who trades items (items) used in the game. . Accordingly, gamers or users who play online role-playing games generally play games while controlling and controlling NPCs controlled by the game service system while controlling and controlling main characters or avatars on behalf of the user.

In addition, in recent years, not only the user character and the NPC fight against each other, but also the type of game (e.g., Blizzard) that produces a subunit in which the main character of the user plays a role in assisting the user's game play. StarCraft, developed and sold by the company, has been introduced, and the auxiliary units produced in this way are controlled by the game service system and operated. It is designed to be manipulated and controlled by commands, and merely plays a limited role in assisting the user in game play.

As such, the characters used in online role-playing games up to now included only the user's main character, an NPC controlled solely by the game service system, and an auxiliary unit to assist the user's main character. The story and story were also confined to the user's main character and the NPC confrontation or the user's main character confrontation.

Therefore, users can only use standard game characters developed by game developers, and role-playing games in which many game characters play a role in a virtual game environment have an extremely limited form of game. There was no choice but to. Accordingly, a new type of online role-playing game service based on game characters is always required.

The present invention has been made to solve the above problems, the NPC (Non-playing charater) controlled by the game service system to be operated and controlled in accordance with the NPC role command input from the user terminal, the NPC An online role-playing game service method, system, and a recording medium thereof, which allow a user to play a role of assisting a user's game play in a virtual game environment.

The present invention provides an entirely new type of online game for controlling an NPC controlled by a game service system to a user terminal, and makes the NPC play a role of assisting a user's game play. It is an object of the present invention to allow an NPC to produce an item for a user, to collect materials for making an item, to manage a user's land or building, or to deliver an e-mail or a memo to the user.

In addition, the game service system according to the present invention enables the user to control the NPC only when the user character in the game requests a battle to the NPC within a predetermined range or captures the NPC through the battle while the game is in progress. It is possible to make the effort to achieve a predetermined condition during the course of the game, through which to enable a variety of game story progress and more exciting game progress. In addition, in receiving an NPC role command for controlling the NPC from a gamer, two or more NPC role commands divided by date, time, space of game environment or role are simultaneously inputted or sequentially or at predetermined time intervals. The goal is to provide online role-playing games that can be managed over and over again by the gamers.

One preferred embodiment of the present invention for achieving the above object is an online role-playing game (RPG) service method. That is, in a game service method of an RPG service system that provides an online role-playing game (RPG) to a user terminal through a network, the RPG service system includes a user including one or more user character records therein. Maintaining a character database, wherein the user character record includes a field for a user character identifier and user character capability information associated with the user character for each user character; The RPG service system maintains an NPC database including one or more non-playing charater (NPC) records therein, wherein the NPC record includes NPC role performance information associated with the NPC for each NPC and a user character identifier associated with the NPC. And a field for NPC role command information associated with the user character identifier; When a selection and control request for an NPC performing a predetermined role is input from a gamer controlling a user character through the user terminal, the RPG service system requests a selection and control for the input NPC. Receiving from the user terminal through a network; The RPG service system, retrieving user character capability information associated with the user character of the gamer by referring to the user character database according to the received selection and control request; The RPG service system, when the retrieved user character capability information is greater than or equal to a predetermined size, includes the user character identifier of the user character in an NPC record of the NPC that has received the selection and control request, and includes the NPC record in the NPC database. Recording; If at least one NPC role command is input through a user terminal from a gamer controlling the user character, the RPG service system receiving the input NPC role command from the user terminal through a network; And allowing the RPG service system to perform NPC role command information associated with the recorded user character identifier according to the received NPC role command by the NPC receiving the selection and control request. .

Another preferred embodiment of the present invention is an online role-playing game (RPG) service system. That is, in an online RPG service system for providing an online role-playing game (RPG) to a user terminal through a network, the online RPG service system includes one or more user character records, wherein the user character record is a user character identifier for each user character. A user character database including a field for user character capability information associated with the user character; And one or more non-playing charater (NPC) records, wherein the NPC records include NPC role performance information associated with the NPC for each NPC, a user character identifier associated with the NPC, and NPC role command information associated with the user character identifier. An NPC database containing fields; If the selection and control request for the NPC and the at least one NPC role command are input from the user terminal from the gamer controlling the user character according to the NPC role performance information, the input selection and control request and role An input unit for receiving a command through a network; In response to the received selection and control request, when the user character capability information associated with the user character of the gamer is equal to or greater than a predetermined size by referring to the user character database, the NPC receiving the request for selecting and controlling the user character identifier of the user character First control means for including in the NPC record of the record and recording the NPC record in the NPC database; And second control means for causing the NPC role command information associated with the recorded user character identifier to be performed by the NPC receiving the selection and control request according to the NPC role command received by the input unit.

** Organization of terms used in this specification **

1) User Character

As used herein, a user character refers to an object that operates in response to a gamer's operation for advancing a game on an online RPG game, and is controlled by an operation command signal input from a user terminal. It is a concept that encompasses a character, an avatar, or a game player on behalf of a user or a gamer.

2) NPC (non player character)

As used herein, NPC generally refers to a character manipulated by a computer (game system). In other words, it means any game character that is not directly controlled by the gamer or the user. This includes an NPC controlled by a computer by specifying a counterpart of a gamer manipulated by a computer or a gamer to represent itself. By way of example, the NPC may be a 'monster character' that trades a 'monster' or 'mob' or items (items) used in the game, in which users must kill to increase their score and fight against the user. And the like.

Hereinafter, one preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The invention may be better understood by the following examples, which are intended for purposes of illustration of the invention and are not intended to limit the scope of protection defined by the appended claims.

1 is a flowchart illustrating an online role-playing game service method according to an exemplary embodiment of the present invention. The online role-playing game service method according to the present embodiment is performed by a predetermined online role-playing game service system.

The present invention shown here first relates to an online role-playing game method, and more particularly, to provide a role-playing game in which a plurality of game characters play a role in a virtual game environment. More specifically, the present invention relates to a game service method of an online role-playing game system for providing a plurality of users with the above-described role-playing game through a network. The predetermined role means any work or action that a game character performs for a specific purpose in the game without being particularly limited.

First, as shown in FIG. 1, the RPG service system according to the present invention connects the user terminal of the user to the RPG service system so that a plurality of users can access the RPG service system (S101). Member registration or login process can be made (S102). This connection procedure and login procedure can be any method used in a general game service system.

Specifically, if the user authentication is confirmed through a user login process such as the normal membership registration and authentication, the game service system according to the present invention maintains a user character database including one or more user character record (S110) Go through). The user character record includes a field for a user character identifier and user character capability information associated with the user character for each user character.

2 is a diagram illustrating a user character database including a user character record 200 according to an embodiment of the present invention. In FIG. 2, a user character identifier 201 is used to indicate an association between each information and a user character. The user character identifier 201 is identification information for identifying a character used by a specific user or a gamer among a plurality of user characters. The user character capability information 202 is capability point data given to a specific user character as the online RPG game progresses. The point data may be provided to the user in association with the user terminal.

According to an embodiment of the present invention, the user character capability information 202 means numerical data as a reward concept to a game character leveling up when a predetermined condition is satisfied, and for example, a game character collected as a game progresses. It may be a kind of score that is given from the game service system when the experience data of s reaches a predetermined level up event occurrence value. In the present embodiment, it is most preferable that a point value of a predetermined value is given by the user character capturing a monster or mob while the game contents are in progress. However, as a result, the point data of a predetermined value is given according to the level up of the user character. There may be various point data granting methods such as granting data, granting event castle point data during game play, granting bonus castle point data upon completion of quests, and flexibly adopted by the operator of the present system. .

The user character capability information 202 is data used for recording user character information in the NPC database according to the capability value of the user character when a selection and control request for the NPC described later is input. Here, the user character capability information 202 may be set differently in response to the selection and control request for the NPC according to the capability level. In other words, no matter how high a user's character is, it can be set to only respond to NPCs that match that capability level. Referring to FIG. 2, for example, a user character corresponding to the user character identifier "A100001" may be assigned to an NPC having an NPC level of "2" or higher because the user character level is "1" even if the user character capability value is "300". It is possible to prevent the response from being received even if the selection and control request is made.

In step S120, the game service system according to the present invention maintains an NPC database including one or more non-playing charater (NPC) records. The NPC record includes fields for NPC role performance information associated with the NPC for each NPC, a user character identifier associated with the NPC, and NPC role command information associated with the user character identifier.

3 illustrates an NPC database including one or more NPC records 300 in accordance with one embodiment of the present invention. As shown in FIG. 3, the NPC role performance information 302, the user character identifier 305, and the NPC role command information 306 are classified and stored for each NPC in each field of the NPC record 300. It is. That is, NPC information for one NPC is stored in one NPC record, and the NPC record includes the NPC role performance information, the user character identifier, and the NPC role command information. It is related by NPC.

The NPC role performance information 302 may be recorded in association with a specific NPC in the NPC database, and the associated NPC role performance information indicates which role the NPC can play by the game service system. The NPC role performance information used in the present invention means data information on the role played by the NPC in the virtual game environment. In particular, a game service system (or game providing server) that provides an RPG manipulates the role of the NPC. And information to control. That is, information for operating the NPC according to the game logic determined by the game service system. According to this NPC role performing information, the NPC deals with the user character by the game service system or the role for the game story progression (for example, the monster or mob battles with the user character or the transaction with the user for the game story progression). Such as the role of a merchant).

The user character identifier 305 may be recorded in association with a particular NPC in the NPC database, such a user character identifier associated with the NPC indicates which user character the NPC is associated with. That is, the user character identifier 305 is to correspond to the NPC having a specific NPC identifier and the user character having a specific user character identifier. Therefore, it is preferable that one user character identifier is included for each NPC in the NPC record of the NPC database. This is data that is used later to determine which user character will perform the given NPC role command information 306 in performing the NPC role command received from the gamer in the virtual game environment.

The NPC role command information 306 may be recorded in association with a particular user character identifier in a particular NPC record of the NPC database, and so the associated NPC role command information 306 may indicate what role an NPC has for any user character. Indicates whether to perform The specific user character identifier to which the NPC role command information 306 is associated and recorded may be a user character identifier 305 included in the NPC record, or may be a user character identifier included in the user character record. The user character identifier may be both of the above in that it is an object of the NPC role command performed by the NPC, but the NPC record includes a user character identifier 305 and NPC role command information 306 for each NPC. In that sense, the particular user character identifier is preferably a user character identifier 305 included in the NPC record.

The biggest difference between the NPC role command information 306 used in the present invention and the NPC role performance information 302 is that a user or a gamer who plays an RPG can manipulate and control the role of the NPC. Information (the NPC role performance information 302 is controlled by a game service system). That is, it is control information that enables the NPC to play a predetermined role regardless of the game logic determined by the game service system. This is merely a command for the user or the gamer to control the NPC, in fact, the real-time movement of the NPC can be executed by the game system. According to the NPC role command information 306, the NPC assists the user in playing the game according to the NPC role command input from the user terminal (for example, an item producing role for the user character, an item collecting role, an e-mail or Role of delivering message, role of secondary attack, etc.).

As the online RPG game progresses, the NPC plays a predetermined role in the virtual game environment, while advancing the game story with the user character. For example, when a gamer connects to an online RPG and starts a game, the NPC is manipulated and controlled by the game service system to deal with the user character or trader with the user character according to the NPC role performance information 302. Can play a role. Therefore, the NPC role performance information 302 is preferably determined in advance according to the game logic of the game service system from the initial time when the game is provided and recorded in the NPC database. However, the user character identifier information 305 associated with the NPC may not be provided from the beginning. This is because the user character identifier information 305 is preferably recorded in the NPC database only when responding to the selection and control request for the NPC according to the present invention as described below. In addition, the NPC role command information 306 is information for the user or the gamer to manipulate and control the role of the NPC, but this means that the gamer operates accordingly when the user inputs a predetermined NPC role command. The NPC role command information 306 is also recorded in advance in the NPC database for execution and implementation. The NPC role command information 306 may be predetermined for each NPC, but may be changed according to the NPC level or the NPC experience value as described below.

For example, with reference to FIG. 3, the NPC database according to the present invention has NPC records 300 classified by NPCs by NPC identifiers 200001, 200002, 300001, 400001, 301, among which " 200001 " The NPC having the NPC identifier 301 plays a role corresponding to "monster" by the game service system when the game is started, and the NPC role from the gamer when the user character identifier 305 of "A100001" is recorded as described below. In order to receive a command and perform the “item production” role described in the NPC role command information 306 for the user character “A100001” corresponding to the identifier. To this end, the NPC record 300 of the NPC database according to the present invention includes fields for NPC role performance information 302, user character identifier 305, and NPC role command information 306 associated with the NPC for each NPC. It is preferable.

According to another embodiment of the present invention, the NPC role command information 306 has different role command information for each NPC, as shown in FIG. 3. By having different NPC role command information 306 for each NPC that a gamer selects and requests for control, the present invention allows the gamer to select an NPC to select from among a plurality of NPCs and to control his game. It is possible to actively find an NPC capable of performing role command information suitable for play and use the NPC in various ways. Therefore, the NPC role command information 306 is not particularly limited as long as it serves to assist a game character's in-game game play.

4 is a schematic diagram for schematically describing various NPC role command information 306 according to an embodiment of the present invention, and the NPC role command information 306 is modified and modified by a game service system operator according to the present invention. For example, as illustrated in FIG. 4, the NPC role command information 306 may be an item producing role or item for a user character having the user character identifier of the NPC in a virtual game environment. It is possible to perform a collection role, a role of delivering a mail or a message, a service role of treating a user character or increasing the life of the user character, a role of increasing the user character's ability or attack power, or a secondary attack role.

In step S130, the game service system according to the present invention receives a selection and control request for an NPC performing a predetermined role according to the NPC role performance information 302 from a gamer controlling a user character. When a gamer selects any one of the one or more various NPCs encountered while playing a game using a user character, the selection signal is received by the online RPG system according to the present invention. The NPC selected by the gamer may be arbitrarily selected from among NPCs generated in game content. That is, one NPC may be randomly selected from among NPCs having various kinds / levels / role performance information recorded in the NPC database. Then, the game service system according to the present invention may determine the selected NPC as an NPC corresponding to the user character of the gamer.

According to another embodiment of the present invention, if the user character and the NPC is within a certain distance in the game to receive the selection and control request for the NPC and determine the selected NPC as the NPC corresponding to the user character of the gamer. It can be limited. In other words, the game service system according to the present invention does not determine all of the gamers in response to the gamers selecting randomly one among all the NPCs recorded in the NPC database, but the user character in the game applies for battle to the NPC within a certain range. In response only to the case, only the NPC that has received the battle request is determined as the NPC corresponding to the user character of the gamer.

5 is a flowchart illustrating a method of receiving a selection and control request for an NPC according to a distance between a user character and an NPC according to an embodiment of the present invention. As shown here, receiving the selection and control request for the NPC from the gamer controlling the user character (S130), receiving a battle request for the NPC from the gamer controlling the user character (S510) ); Retrieving observation range information on the user character by referring to the user character database (S520); And when the distance information between the user character and the NPC is smaller than the retrieved observation range information, the battle request is established (S530).

To this end, first, the user character record 200 preferably further includes a field for observation range information 204 of the user character, as shown in FIG. 2. This represents the range information of the space in the game environment that can be observed by the user character on the online game, and the battle with the NPC included in the observation range information 204 is enabled. In addition, when a battle request is simultaneously received from two or more user characters, the user character having a relatively large value of the observation range information 204 may be controlled to have a preemptive right to request a battle. The observation range information 204 may be determined differently according to the type or capability of the user character.

For example, referring to FIGS. 2 and 3, a user character and an NPC are located in a space in a virtual game environment, the user character identifier of the user character is "A100001", and the NPC identifier information of the NPC is "200001". When the game service system according to the present invention receives a battle request for the NPC from the gamer controlling the user character, the observation range information of the user character with the user character identifier "A10001" with reference to the user character DB ( 204 and the location information 205 are searched, and the location information 308 of the NPC having the NPC identifier "200001" is searched by referring to the NPC DB. As a result of the search, the observation range information 204 of the user character is " 45 ", the position information 205 of the user character and the position information 308 of the NPC are values of (25, 30) and (03, 15), respectively. You can get it. Thus, it can be determined that the distance information (about 27) of the user character and the NPC is smaller than the observation range information 204 of the user character. Accordingly, the NPC is located in the observation range information of the user character, thereby enabling the battle between the user character and the NPC.

Even if a predetermined NPC capable of performing an attack by a gamer controlling a user character in a space in a virtual game environment is found, if the NPC is not included in the user character's observation range, a battle request of the user character may be established. The battle between the user character and the NPC does not occur.

Another embodiment of the present invention is as shown in FIG. 6 is a flowchart illustrating a method of receiving an NPC capture signal and receiving a selection and control request for an NPC according to an embodiment of the present invention. As shown here, after the combat request is established (S530), the present invention includes receiving an NPC capture signal indicating that the NPC has been captured by a user character in a virtual game environment (S540); And updating the user character capability information according to the received NPC capture signal (S550).

That is, as shown in FIG. 7, when the battle request of the user character is established in the case where the distance between the user character and the NPC is equal to or less than a predetermined range (S530), a battle is made between the user character and the NPC accordingly. Only when the user character wins the NPC in the battle and captures the NPC (S540), the user character's ability value is updated (S550). 7 is a schematic diagram schematically illustrating a process of capturing an NPC and updating a user character capability value according to an embodiment of the present invention. Accordingly, in the online RPG system according to the present invention, when the user character loses 1: 1 combat with the NPC, the user character ability information may not reach a predetermined size, thereby ultimately preventing the gamer from using the NPC. Do. According to the present invention, the user character capability information 202 of the user character database shown in FIG. 2 is the form in which the user character captures the NPC (monster or mob) while the game content is in progress so that a predetermined value of point data is given. desirable.

In addition, the NPC capture signal may have different information or data for each NPC captured. That is, it has information that some kind of NPC (specifically, some kind of monster, mob or merchant character) has been captured. This is because, as will be described later, the NPC role command information to be performed by the NPC may be different according to the types of captured NPCs, that is, different NPC capture signals.

Furthermore, as long as it has the above characteristics of the present invention, the method or apparatus for receiving the NPC capture signal from the user terminal that the game service system according to the present invention has captured the NPC is not particularly limited, and the technology to which the present invention belongs It is apparent that all known to the person skilled in the art and modified methods or apparatus thereof can be used.

As described above, there may be various methods for receiving a selection and control request for the NPC from a gamer controlling the user character and determining the selected NPC as an NPC corresponding to the user character of the gamer. Another embodiment of the present invention for this purpose is to respond when a selection and control request comes only from a user character with a constant user character level 203 according to the NPC level 303 described in FIG. 3. For example, with reference to FIGS. 2 and 3, even if the user character corresponding to the user character identifier "A100001" has the user character capability value information 202 "300", the user character level 203 is "1". Even if a selection and control request is received for an NPC having an NPC level 303 equal to or greater than "2" (when the NPC identifier is 200002 or 400001), the game service system according to the present invention cannot receive any decision or response thereto. It is possible to do

In operation S140, the user character capability information 202 associated with the user character of the gamer is referred to by referring to the user character database according to the received NPC selection and control request. This is to make the NPC available only to user characters with certain conditions. Accordingly, the user character level information 203 indicating the user character level information 202 as well as the user character capability value information 202 may be searched for and used.

The online RPG system according to the present invention receives a selection and control request for the NPC from a gamer controlling a user character, and whether the received NPC selection and control request signal is appropriate by referring to the user character database or the NPC database. After determining that the signal is inappropriate or does not meet certain conditions, it may be implemented to notify via a pop-up window or the like that the selection and control request cannot be responded to.

In step S150, when the searched user character capability information 202 or / and user character level information 203 is equal to or larger than a predetermined size, the NPC receiving the request for selecting and controlling the user character identifier 201 of the user character In the NPC record 300, and records the NPC record 300 in the NPC database. The inclusion of the user character identifier 201 in the corresponding field of the NPC record 300 (ie, user character identifier 305 of FIG. 3) is for associating a particular NPC with a user character. That is, the NPC that receives the selection and control request determines for which user character the NPC role command to be described below is performed. Accordingly, a user character whose user character capability information 202 or / or user character level information 203 is greater than or equal to a predetermined size may select an NPC corresponding to the NPC record 300 including the user character identifier 305. Can be used as a supplement to your own gameplay.

As such, when the user character identifier 305 is recorded to be associated with a specific NPC in the NPC database, the NPC is determined to perform an NPC role command input from a gamer. Accordingly, the NPC may perform the NPC role command information 306 according to the NPC role command input from the gamer rather than the NPC role performance information 302 manipulated and controlled by the game service system. To this end, in the step of recording the NPC record in the NPC database, the present invention deletes the NPC role performance information 302 from the NPC record 300 and deletes the NPC record 300 into the NPC database. The recording may further include.

According to another embodiment of the present invention, the user character identifier 305 is recorded in the NPC record as described above, and the appearance of the in-game image of the NPC corresponding to the NPC record 300 may be changed. 8 is a flowchart illustrating a process of changing the appearance of an image in a game of an NPC according to an embodiment of the present invention. As shown herein, the present invention includes the steps of recording the NPC record 300 in the NPC database. (S150), deleting the NPC primary image information (304) from the NPC record (300) and recording the NPC record (300) in the NPC database (S810); And executing the NPC secondary image information 307 included in the NPC record 300 (S820).

To this end, the above-described NPC record 300 preferably further includes fields for NPC primary image information 304 and NPC secondary image information 307 associated with the NPC. Here, the NPC primary image information 304 and the NPC secondary image information 307 are data about image information representing the appearance of the NPC game. The online RPG system according to the present invention can implement various image appearances of the NPC in the game by using such image information. Accordingly, in the present invention, when the user character capability information 202 or / or the user character level information 203 is greater than or equal to a predetermined size, the present invention provides the user character capability information 202 or / or the NPC record 300. And when the user character level information 203 is recorded in the NPC database, that is, when the NPC role command execution target of the NPC is determined, the NPC primary image information 304 is deleted from the NPC database, and the NPC secondary is deleted. By executing the image information 307, the appearance of the in-game image of the NPC can be changed. According to the present invention, it is possible to change a predetermined role in the game of the NPC and to update the image appearance newly.

In step S160, the game service system according to the present invention receives at least one NPC role command from a gamer controlling the user character. This is to change an NPC role in the game by receiving an NPC role command for manipulating and controlling the NPC from the gamer. The NPC role command is associated with the NPC role command information 306 described in the NPC database, and may be a command signal for executing the NPC role command information 306. For example, with reference to Figure 3, the NPC role command is a control command signal from the gamer to perform the role that NPCs produce items, collect items or deliver mail or messages. The NPC role command includes all operation commands for manipulating or controlling the role of the NPC, regardless of the game logic defined by the game service system, by the user or the gamer who plays the RPG. The movement and operation of the NPC in real time in the game is preferably implemented by the game service system.

According to another embodiment of the present invention, at least one NPC role command received from the gamer controlling the user character is two or more NPC role commands classified by date, time, space of the game environment, or role.

Here, the NPC role commands are two or more NPC role commands separated by dates, so that gamers manipulate and control the in-game roles of the NPCs by date so that the NPCs perform different roles by separating the NPCs by date. Can be entered. For example, it may be possible to enter an NPC role command to produce an item from some time to some time, or to enter two or more NPC role commands to perform the NPC role command only at any time and at any time. Here, the date may be an offline date to which a user outside the game belongs or a virtual date flowing in the game. In addition, when two or more NPC role commands are input, the two or more NPC role commands may be input simultaneously or sequentially, or may be input at a predetermined time interval before the input NPC role commands are executed. have. The fact that the two or more NPC role commands are divided by time is also the same principle as that by date.

The NPC role command may be two or more NPC role commands divided by spaces of a game environment. The NPC role commands may be located at different positions within a virtual game environment, or different NPC role commands may be input according to the space where the NPC is located. Can be. For example, the NPC may be located in a user area of a user character to perform a predetermined NPC role command, and in this case, may play a role in producing an item, and the NPC may be located in a field not belonging to the user area. It can be located and, in this case, it can be used to collect items.

The two or more NPC role commands in which the NPC role commands are divided by roles are different kinds of NPC role commands that the NPC should perform. For example, you may enter more than one NPC role command to produce an item until sometime and an NPC role command to collect an item sometime.

In step S170, the NPC role command information 306 associated with the recorded user character identifier 305 is performed by the NPC that has received the selection and control request according to the received NPC role command. This means that the online RPG system according to the present invention causes any NPC recorded in the NPC database of FIG. 3 to be associated with the user character identifier 305 for the user character corresponding to the user character identifier 305 associated with the NPC. Role command information 306 to be performed. For example, an NPC named "200001" that played a "monster" role by the game service system changed the role of the NPC in the game so that it played a role of "producing an item" for the user character "A100001". It is to let.

According to the present invention as described above, the NPC performing a predetermined role in the virtual game environment can be converted to play a role of assisting in-game play of the user character. That is, the present invention mainly provides a conventional 'NPC', which performs a role of fighting against a user's opponent or a user in a virtual game environment, by a user or a user terminal through a predetermined process according to the present invention. It is newly transformed into 'slave-NPC' which is controlled by command signals, thereby enabling the user's play in a virtual game environment.

Another embodiment of the present invention exhibiting such a feature is that the step (S160) of receiving the at least one or more NPC role commands and the step (S170) of allowing the NPC role command information to be performed by the NPC are repeatedly performed. . In other words, after recording the user character identifier in the NPC database, the game service system according to the present invention may repeatedly receive an NPC role command from the gamer and execute it. That is, it is possible to continuously receive the NPC role command, the NPC can be managed according to the intention of the gamer.

Another embodiment of the present invention is characterized in that for updating the experience value of the NPC according to the role played by the NPC by the NPC role command information. Here, the experience value is not particularly limited as long as it represents the in-game experience of the NPC, and may be, for example, a numerical value or an index indicating the level, level, or ability of the NPC. That is, this may be indicated as NPC level 303 in FIG. 3.

To this end, the NPC database may further include NPC experience information associated with the NPC, and as shown in FIG. 9, after the step of allowing the NPC role command information to be performed by the NPC (S170), the NPC role The step of updating the experience value of the NPC performing the command information (S171); characterized in that it further comprises. For example, although the NPC experience value according to the present invention was "1", the NPC experience value "2" or "NPC role command information to assist the user's game play by receiving an NPC role command from a gamer was performed. Increase to 3 "or more. That is, the stats may increase or decrease according to the type of the role played by the NPC or the difficulty of the performed role, and the stats may increase or decrease over time when the NPC plays the role. Depending on the role played by the player, it is possible to be completely destroyed within the game environment. By increasing the experience of the NPC, the present invention can increase the effect of the same role played by the NPC in the game, and by reducing the experience of the NPC, it can also lead to the discovery of new NPCs and increase the profits of the game system operators. have.

According to another embodiment of the present invention, after updating the experience value of the NPC as shown in FIG. 10 (S171), updating the NPC role command information 307 according to the updated experience value of the NPC. It goes through (S172). Accordingly, the online game service system according to the present invention can change the role that the NPC can perform by changing the NPC role command information 307 as the NPC experience value increases. FIG. 11 is a schematic diagram schematically illustrating a state in which a role of an NPC changes according to an embodiment of the present invention. FIG. As shown here, when the NPC's experience value is "2", the NPC can play a role of collecting items, and when the NPC's experience value is "3", it can play a different role of delivering a mail or a message. You can do it. Through this, the user can convert the NPC according to the present invention, the NPC to perform a different role, before reducing the experience, can use one NPC in a variety of ways, depending on the game story or content or environment that follows You can actively use various NPCs.
