The computer of the game device 2 and the computer of the server device 3 constitute the control unit 4 of the game system 1.

  Then, as shown in FIG. 2, the control unit 4 of the game system 1 executes the game programs 30 a and 33 a of the present invention, whereby the game stage generation unit 41, the mission execution unit 42, the reward determination unit 43, the virtual space Functions such as the generation unit 44 and the game control unit 45 are exhibited. For example, among these functions, the game stage generation unit 41, the mission execution unit 42, and the reward determination unit 43 are configured as computer functions of the server device 3 by the game program 33a. That is, the server device 3 includes a game stage generation unit, a mission execution unit, and a reward determination unit. In addition, the virtual space generation unit 44 and the game control unit 45 are configured as functions of a computer of each game device 2 by the game program 30a. In addition, the game stage generating means 41 includes a session forming means 410.

  The virtual space generation means 44 generates a virtual game space (hereinafter, simply referred to as a virtual space) of a game in which a plurality of users can participate. Various objects are arranged in the virtual space. The objects include a plurality of player characters P1, P2 operated by each of a plurality of users, and non-player characters such as an enemy character E. A virtual camera is arranged in the virtual space, and the imaging range of the virtual camera is displayed on the game screen as a two-dimensional image. The virtual camera is arranged, for example, behind the player character by a predetermined distance.

The game control means 45 causes the corresponding player character to act in the virtual space based on the operation input of each user, and advances the game. The game control unit 45 controls the operation of other objects such as a non-player character in the virtual space according to the action of the player character and the progress of the game.

  The game stage generating means 41 generates a common game stage in which a plurality of users participate and player characters corresponding to each user act in the same virtual space. The session forming means 410 determines two or more computers to be synchronized from among the plurality of computers, and forms a session for synchronizing the two or more computers. The session forming means 410 accepts participation of a plurality of users operating each computer in the game. The session forming means 410 performs communication between computers of each user when forming a session.

  The mission executing means 42 selects and executes a mission to be executed on the user's computer from a plurality of missions, based on the operation of the user. In each of the plurality of missions, information on a start position, an end position, a reference position, and an achievement condition of each mission is set.

  The start position is an initial position of the player character in the mission. That is, the start position is a start position where the player character is arranged on the common game stage when starting the mission.

  The end position is a position of a place necessary for the player character to accomplish the mission. For example, if the achievement condition is to reach the point B, the point B is the end position. For example, if the achievement condition is to defeat the boss character appearing at the point C, the position at which the point C appears is the end position.

  The reference position is set on a path between the start position and the end position of the mission. The reference position will be described later.

  The achievement condition is set as a clear condition of the game in the mission. The achievement conditions include, for example, reaching a target position, defeating a predetermined character such as a boss character, meeting a predetermined non-player character (conversing, rescuing, etc.), and obtaining a predetermined item. And so on.

  Further, a game stage, information on non-player characters appearing in the game stage, and environment information are set for each of the plurality of missions. The information on the non-player character includes information on the type, level (strength, etc.) of the non-player character, items obtained when the player is defeated, and the like. The environment information includes various information such as the in-game time (day, night, etc.) at the start of the mission and the weather (sunny, rainy, etc.).

  The reward determining means 43 determines a reward to be given to each user based on the content of the game on the game stage. The reward includes a main reward for achieving the mission selected by the user and a sub-reward for cooperating with the mission selected by another user who has participated in the common game stage.

[Generating a common game stage]
Hereinafter, a generation mode of the common game stage in the present embodiment will be described in detail with a specific example. First, each user selects a mission to be executed from among a plurality of missions. When the mission is determined, each user's computer (game device 2) transmits a matching request signal to the server device 3.

The server device 3 stores information on the user who transmitted the matching request signal and information on the selected mission. The session forming means 410 forms a session with the plurality of game devices 2 based on the information of the user and the information of the selected mission. In the present embodiment, a session is formed on the server device 3. Information on the formed session is stored in the storage device 28 of the server device 3.

  Here, the game stage generating means 41 can join a plurality of users who have selected different missions to one session. For example, one user (first user) who has selected the first mission and another user (second user) who has selected the second mission can participate in a common game stage.

  Further, the game stage generating means 41 gives priority to the users who have selected a plurality of missions in which the distance between the reference positions set in the mission selected by each user is within the reference distance to the game in the common game stage. Participate. Hereinafter, a specific example will be described.

  FIG. 3 is a flowchart showing a flow of generating a common game stage in the present embodiment. In the present embodiment, the game stage generating means 41 forms a session in which the selected missions participate in the same user for each mission, and a plurality of missions corresponding to a plurality of missions whose distance between the reference positions is within the reference distance. Prioritize sessions into games on common game stages.

  First, when the first user selects the first mission, a matching request signal is transmitted from the computer of the first user to the server device 3. When receiving the matching request signal (step S1), the session forming means 410 selects a session with less than the capacity (for example, four persons) and the first mission from the session list temporarily stored in the server device 3. A session in which the user participates is searched and matched (step S2). The session in which the first user participates is referred to as a first group.

  Similarly, when the second user selects a second mission different from the first mission, a matching request signal is transmitted from the computer of the second user to the server device 3. Upon receiving the matching request signal, the session forming means 410 sets a session of less than the capacity (for example, four) and a session for the user selecting the second mission from the session list temporarily stored in the server device 3. Search and match. A session in which the second user participates is referred to as a second group.

  The game stage generating means 41 determines whether or not there are a plurality of users who have selected a plurality of missions whose distance between the routes is within the reference distance (step S3). More specifically, the game stage generation unit 41 reads out information of the first mission corresponding to the first group, reads out information of the second mission corresponding to the second group, and stores a reference position of the first mission, It is determined whether or not the distance (inter-path distance) from the reference position of the second mission is within the reference distance.

  When there are a plurality of groups (sessions) before the start of the game or during the execution of the game, the game stage generation unit 41 performs the same determination for each reference position, and extracts another corresponding group.

If there is a corresponding session in the determination in step S3 (Yes in step S3), the game stage generation unit 41 determines that the first group and another group (second second) whose path distance between the first group is within the reference distance. And the like) are made to preferentially participate in the game in the common game stage (step S4). If there is a plurality of other groups corresponding to the determination in step S3, the game stage generation unit 41 causes the first group to participate in a common game stage with another group having a shorter distance between routes.

  In this embodiment, each group is not notified that another group has participated in the common game stage.

  When deciding the groups to participate in the common game stage, the game stage generating means 41 calculates the average of the player levels of the users included in each group, and sets the group level. Then, the game stage generating means 41 causes groups having close group levels to each other (for example, groups having a difference in group level within ± 10 levels) to participate in a common game stage. Thereby, when a plurality of groups participate in a common game stage, it is possible to prevent the effect of another group from becoming excessively large, such as a great change in the difficulty of the game.

  When the first group participates in a common game stage with the second group, the game stage generation unit 41 includes the first group in a game stage in which player characters operated by each user included in the second group are arranged. A player character operated by each user is arranged. The placement position of the player character is the start position of the mission executed by the first group.

  If there is no session less than the capacity and there is no session in which the user who has selected the first mission participates, the session forming means 410 forms a new session with the first user as a host. When there is no other group corresponding to the determination in step S3 (No in step S3), the game stage generation unit 41 causes the first group to participate in a new game stage (step S5).

  After the common game stage is generated, the game proceeds by the game control means 45 in each user's computer. At this time, on the computer of the first user, the player character corresponding to another user (second user) participating in the common game stage is controlled by the game control means 45 of the computer operated by the second user.

  The control information of the player character of the second user is sent to the computer of the first user via the communication network NW. In the computer of the first user, the game control means 45 controls the movement of the player character of the first user in the virtual space based on the operation of the first user, and based on the control information sent from the computer of the second user. Controlling the movement of the player character corresponding to the second user in the same virtual space.

  4 and 5 are diagrams illustrating an example of a virtual space (a common game stage) in which two missions are executed in the present embodiment. In the example of FIG. 4, the first mission is to move from point A to point B, and the second mission is to move from point C to point D.

  In the first mission, a reference position V1 is set on a route M1 from point A to point B, and in the second mission, a reference position V2 is set on a route M2 from point C to point D. The two reference positions V1 and V2 are located within a predetermined reference distance from each other. For example, in FIG. 3, the other reference positions V2 and V1 are included in predetermined ranges W1 and W2 based on one of the reference positions V1 and V2.

The first user who has selected the first mission operates the first player character P1 to move the first player character P1 from the start position A to the end position B while fighting the enemy character E. In addition, the second user who has selected the second mission has the second user.
By manipulating the player character P2, the second player character P2 is moved from the start position C to the end position D while fighting the enemy character E.

  The game control means 45 controls the action of the enemy character E, which is a non-player character, according to the action of the player characters P1 and P2 operated by the user participating in the session. For example, in the present game, a part of the enemy character E moves on a common game stage. It is assumed that the second player character P2 operated by the second user attacks the enemy character E with a gun when the above two missions are being executed in parallel on the common game stage (virtual space S). . In this case, the game control unit 45 sets the enemy character E located within a predetermined range from the sound source position of the gun firing sound in the direction in which the gun firing sound is heard, that is, the direction in which the second player character P2 is located. Move to

  In the present embodiment, the upper limit number of enemy characters E that can exist in a predetermined area of the common game stage is determined. For example, the upper limit number of the enemy characters E in a predetermined area including the points A, B, C, D, and the reference positions V1 and V2 is set to six. In this case, when the enemy character E moves in the direction in which the second player character P2 is located by the firing of the second player character P2, the number of the enemy characters E on the route M1 of the first mission decreases. As a result, the probability that the first player character P1 encounters the enemy character E decreases.

  Another example will be described. FIG. 6 and FIG. 7 are diagrams showing another example of the virtual space in which two missions according to the present embodiment are executed. 6 and 7, the route M1 of the first mission and the route M2 of the second mission intersect at the reference position V1. The reference position V2 is the same position as the reference position V1.

  Also in the present example, for example, when the second player character P2 fires a gun, the enemy character E moves in the direction in which the second player character P2 is located by the firing sound of the gun. In this example, as shown in FIG. 6, a passage F extending toward the reference position V1 is provided, and a part of the enemy character E can move to the reference position V1 through the passage F.

  The enemy character E gathers at the reference position V1 due to the sound of the second player character P2 firing the gun. As a result, the number of enemy characters E on the route M1 of the first player character P1 increases.

  On the other hand, for example, the first mission includes setting an obstacle (object) G at the exit of the passage F as an achievement item. As shown in FIG. 7, it is assumed that after the first player character P1 has installed the obstacle G at the exit of the passage F based on the content of the first mission, the second player character P2 has fired a gun. In this case, the enemy character E that has passed through the passage F is blocked by the obstacle G and cannot reach each of the routes M1 and M2. As a result, even if the second player character P2 attacks the enemy character E using a gun, the number of enemy characters E hardly increases.

  Alternatively, the first mission may include, as an achievement item, removing an obstacle G that is provided in advance at the exit of the passage F. As the first player character P1 removes the obstacle G, the number of enemy characters E reaching the reference positions V1 and V2 increases.

As described above, according to the present aspect, in a common game stage in which a plurality of users participate, games having different missions are executed. Here, irrespective of the mission selected by each user, even if it is possible to simply participate in a plurality of missions on a common game stage, if the relevance between the plurality of missions selected by each user participating in the common game stage is reduced. In the end, the effect on each other's mission is small, and the game cannot be diversified.

  Therefore, in this embodiment, the reference positions V1 and V2 set on the paths M1 and M2 between the start positions A and C and the end positions B and D of the respective missions are different from each other. Prioritize each other to participate in a common game stage. As a result, even if each of the player characters P1 and P2 acts to achieve the mission selected by each user, the operation of one user tends to affect the mission selected by another user.

  More specifically, the placement or distribution of the enemy character E, the presence / absence of the placement of the object, the position, and the like are variously changed depending on the actions of the player characters P1 and P2. As a result, the action content, route, difficulty level, and the like for achieving each mission change. The effect on the mission varies depending on the number of users participating in the common game stage, the combination of the selected missions, and the progress of each mission.

  Therefore, the game content can be diversified beyond the content of the mission prepared in advance as the game data for the user who plays the game. For this reason, it is possible to provide a game that keeps the user bored while suppressing the game production cost and the amount of game data.

  Further, in the present embodiment, the enemy character E acts according to the actions of the player characters P1 and P2 operated by the users participating in the common game stage. Since the maximum number of enemy characters E that can exist in the predetermined area of the common game stage is determined, the position of the enemy character E in the predetermined area may be biased according to the actions of the player characters P1 and P2. For this reason, the influence of the actions of the player characters P1 and P2 on the mission can be increased.

  The enemy character E dies when the physical strength value becomes 0, and is deleted from the game stage. Therefore, when the player character P1 operated by the first user defeats the enemy character E, the number of the enemy characters E changes (gradually decreases) in the game of the second user participating in the common game stage.

  Further, the game stage generation means 41 enables another user to participate in a game stage in which one user who is already executing a mission is participating. This allows the start times of a plurality of missions included in a common game stage to be different from each other. As a result, even if the combination of a plurality of missions is the same, the influence on each other's mission changes due to the difference in the start time, and the game content can be further diversified.

  Here, the game control means 45 of each computer ends the game in the common game stage when the mission selected by the user operating the computer is achieved. That is, when the second mission is achieved, the second computer ends the game on the common game stage, while the first computer does not end the game on the common game stage.

At this time, the game stage generation unit 41 causes the second user who has selected the second mission among the users participating in the common game stage to leave the game stage, while the other users (first users) continue to operate. Participate in common game stages. Thus, the first computer continues the game. When the first mission is achieved, the game on the computer of the first user is ended. Note that, after the second user leaves, another user is allowed to participate in the game stage. In this case, the game stage generating means 41 can cause another user who has selected a mission whose reference position is located within a predetermined range from the reference position V1 of the first mission to participate in the common game stage.

  Therefore, until the first mission selected by the first user is achieved, the first user can continue the game regardless of the status of other missions. That is, achievement of the first mission selected by the first user is not hindered by achievement of the second mission not selected by the first user.

  In the present embodiment, the game control means 45 of the computer of the first user is different from the first mission selected by the first user among a plurality of missions selected by the user participating in the common game stage. (For example, the second mission). That is, the first user can accomplish not only the first mission selected by himself but also the second mission. The second user can accomplish not only the second mission selected by himself but also the first mission.

  Therefore, not only when the first user has achieved the first mission, but also when the second user has achieved the first mission, the game of the first user in the session ends.

  Thus, not only the mission selected by the user but also the mission selected by the other user can be achieved, and the mission selected by the user is not hindered by the achievement of the mission selected by the other user. Therefore, by adding another mission as a secondary purpose while the primary purpose is the mission selected by the user, the interest of the game can be enhanced.

  After the game is over, the reward determining means 43 performs a reward giving process of giving a reward according to the achievement result of the mission to each user. When the first mission selected by the first user among the plurality of missions executed in the common game stage is achieved, the reward determining unit 43 does not depend on the behavior of the first user in the first mission. A mission achievement reward set for the first mission is provided to the first user. That is, the reward determination means 43 includes the first user not only when the first user has achieved the first mission, but also when the other user (the second user) has achieved the first mission. A mission achievement reward (main reward) according to the achievement of the first mission is given to the user.

  Furthermore, when the first user performs an action that satisfies a reward criterion set in relation to the second mission not selected by the first user, the reward determining unit 43 gives the first user a second mission. A reward (sub-reward) according to the set reward standard is given. The reward criterion is, for example, giving a predetermined amount of damage to a predetermined enemy character, defeating a predetermined number of enemy characters by a predetermined number or more, reaching a predetermined position, etc., according to the content of the mission, or the content of the mission. Various settings are made regardless of the above. The sub reward for the second user to accomplish the first mission may be less than the main reward for the first user to accomplish the first mission. About a reward provision process, it is the same also about a 2nd user.

  In this way, one user can obtain not only the main reward set for the mission selected by himself, but also the sub-reward set for the mission selected by the other user. Thus, one user is willing to take part in missions selected by other users. As a result, the influence of the operation of one user on the mission selected by another user is further increased.

  As described above, according to the present aspect, since the plurality of missions selected by the user participating in the common game stage are influenced by each other, the game content in each mission is determined by a combination of the plurality of missions executed on the common game stage. Can be varied in various ways.

[Other embodiments]
As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above embodiments, and various improvements, changes, and modifications can be made without departing from the gist of the present invention.

  For example, in the above-described embodiment, a mode in which users participating in two sessions in which two different missions are selected participate in a common game stage is illustrated, but three or more missions in which three or more different missions are selected are described. May be able to participate in a common game stage. As the number of different missions closer to the reference position increases, the game content changes in various ways. Therefore, even if the same mission is selected a plurality of times, the content of the game changes each time, so that the user can be prevented from getting bored. However, the upper limit number that a group (or a user) who has selected the same mission in the common game stage may be set.

  Further, in the above embodiment, when there is a plurality of other groups corresponding to the determination in step S3, the game stage generating unit 41 sets the first group to a common game stage with another group having a shorter inter-path distance. The mode of participation is illustrated. Instead of this, when there are a plurality of other groups corresponding to the determination in step S3, the game stage generation unit 41 sets the first group to a group having a larger number of participants among the extracted other groups (sessions). You may participate in a common game stage with the group.

  In the above-described embodiment, the game stage generation unit 41 exemplifies a mode in which groups having close group levels participate in a common game stage. Alternatively, it may be possible to participate in a common group stage regardless of the difference in group level (even if the difference in group level is large). In this case, diversification of the game can be achieved, for example, a group having a higher group level can help a mission of a group having a lower group level.

  A plurality of missions executed in a common game stage may include mutually contradictory missions. For example, the first mission may be a mission to rescue a predetermined non-player character, and the second mission may be a mission to defeat the non-player character. Further, the start position and the end position may be switched between the first mission and the second mission. The route M1 of the first mission and the route M2 of the second mission do not have to intersect as shown in the examples of FIGS. 4 and 5, or intersect as shown in the examples of FIGS. You may. When the routes M1 and M2 intersect, the reference positions V1 and V2 may or may not be the same position.

  The end position of the mission may be fixed to a preset position, or may be moved during execution of the mission, for example, by moving a character (boss character or the like to be defeated) serving as an achievement condition. Good.

  The reference positions V1 and V2 may be event occurrence points in each mission or intermediate points such as save points. The event occurrence point may be set variously, such as a key item place, a search place for accomplishing a mission, a defense place, a place where a specific non-player character is arranged, a place with many enemy characters E, and the like. Further, the reference positions V1 and V2 may be set at the same position as the start position or the end position.

  Further, a plurality of reference positions may be set in one mission. For example, when the reference position is set to the start position, a predetermined relay position on the route, and the end position, the game stage generating unit 41 sets the distance between routes as the start position in one mission and the start position in another mission. A distance between a reference position, a distance between a start position in one mission and an end position in another mission, a distance between a relay position in one mission and an end position in another mission, and A distance between an end position in a mission and an end position in another mission is calculated, and when any one of these distances is within a reference distance, a user (group) participating in the plurality of missions is determined. Give priority to common game stages.

  Note that the distance between the start positions may not be included in the distance between routes. This is because, even if the distance between the start positions is short, it is often considered that the probability that groups following these missions intersect after the game starts is low.

  When another user (or group) participates in a game stage in which one user (or group) already performing a mission is participating, the game stage generation unit 41 determines whether the other user (or group) is already performing the mission. The reference position of the mission being executed by the one user and / or the reference position of the mission scheduled to be executed by another user may be set in accordance with the game progress of the other user. Thus, even when another user participates in the common game stage later, it is possible to increase the degree of influence of the plurality of users on the common game stage.

  For example, the game stage generation unit 41 monitors the game progress of one user who is performing a mission (for example, the current position of the player character operated by the user or the end position at the present time), and appropriately monitors the game progress. The information is stored in the storage device 28 of the server device 3. When a session (group) in which another user participates is formed, the game stage generation unit 41 reads out the game progress status of the user currently executing the mission, and executes the position corresponding to the read game progress status. Set as a reference position in the mission. Then, the game stage generation unit 41 determines the distance between the paths between the reference positions (for example, the start position, the relay position, and the end position) of the mission scheduled to be executed by another user and the reference positions of the mission being executed. The game stage may be calculated and a game stage in which another user participates may be determined based on the calculated result.

  In the above-described embodiment, the mode in which the enemy character E moves in the direction of the sound of the gun firing has been described. In addition to or instead of this, the game control unit 45 may perform control such that the player character or the predetermined non-player character is gathered at a large number. This makes it possible to seamlessly change the status (difficulty and the like) of a plurality of missions participating in a common game stage.

  In the above-described embodiment, a mode in which some characters (enemy characters E) move in the common game stage has been described. Instead of this, it is also possible to adopt a mode in which all characters may move, only a specific character such as a boss character moves, or a specific character does not move and a non-specific character moves. .

  Further, the moving mode of the enemy character E is not limited to the above, and various modes can be adopted. For example, when one player character uses a predetermined item, the game control unit 45 may control the enemy character E such that the enemy character E gathers at the item use position or the player character.

  Further, in the above-described embodiment, a case has been described in which the number of enemy characters E in the common game stage decreases when the player characters P1 and P2 defeat the enemy character E, but this is not a limitation. For example, when the enemy character E is defeated, the game stage generation means 41 may generate (supplement) the enemy character E again in the common game stage so as not to exceed the upper limit number. As a result, the upper limit number of enemy characters E always appears on the common game stage. By setting the place where the enemy character E is replenished at a predetermined position on the common game stage, even in a mode where the enemy character E is replenished, the enemy character E can be suppressed on the common game stage by the defeat. The position changes.

  The enemy character E to be refilled may be a defeated enemy character or another enemy character. The upper limit number of the enemy character E in the common game stage does not include the enemy which is the target of the achievement target such as the boss character.

  Further, the number of enemy characters E may be increased or decreased according to the number of users or groups participating in a common game stage. For example, the number of small fish characters may be set to increase as the number of users or groups participating in a common game stage increases.

  Further, in the above-described embodiment, an example has been described in which the computers of the plurality of game devices 2 and the computer of the server device 3 cooperate with each other to perform the functions shown in FIG. Not limited. For example, all of the functions 41 to 45 may be executed by each of the game devices 2 or may be executed by the server device 3. Further, when the computer of the plurality of game devices 2 and the computer of the server device 3 cooperate with each other to form the control unit 4, any one of the computer of the game device 2 and the computer of the server device 3 may be used for each of the functions 41 to 45. Is not limited to the above example, and various methods can be adopted.

  Further, in the above embodiment, an example in which the virtual space is seamless has been described, but the present invention is not limited to this. For example, a game where the game space is divided into multiple fields, and when moving between fields, the data of the destination field is loaded and the field before and after the movement is switched and displayed. can do.

  Further, in the above embodiment, the fact that the update data has been uploaded to the server device 3 means that when each game device 2 accesses the server device 3 at a predetermined timing such as when the online mode is selected at the start of the game, The mode displayed on the monitor 19 of each game device 2 has been exemplified. Instead, when each game device 2 accesses the server device 3 at a predetermined timing, the update data stored in the server device 3 is downloaded, and the update of the game program 30a and the game data 30b in each game device 2 is performed. The content may be updated and stored in the HDD 14 (ie, automatically updated).

  Further, in the above-described embodiment, the example has been described in which the session is formed in the server device 3, but the session may be formed in any of the plurality of game devices 2.

  Further, in the above-described embodiment, the stationary game device has been described as the game device included in the game system. However, the present invention is also applicable to a game system including a computer such as a portable game device, a mobile phone, and a personal computer. Can be suitably applied.

  INDUSTRIAL APPLICABILITY The present invention is useful for diversifying a game executed in a common game stage by allowing a plurality of users performing different missions to participate in a common game stage.
