Description

  The present invention relates to a program and a game device.

  Conventionally, RPG (Role Playing Game) in which a player character forms a party with other characters and travels through the game world is a classic game, and is popular. In this RPG, when an enemy character is encountered while moving in the game field (map field), the movement in the game field is interrupted and a battle with the encountered enemy character is started. At this time, the game screen is switched from the field screen displaying the game field to a battle screen in which the player character and the enemy character battle each other, but other enemy characters in a predetermined area including the player character are included in the battle screen. What to display is known. That is, a part of the field screen centered on the player character is enlarged and displayed as a battle screen (see, for example, Patent Document 1).

Japanese Patent No. 3699660

  In RPG, a system called “symbol encounter” is known as one of battle systems. In this symbol encounter, not a character itself but a symbol representing a player character (player symbol) and a symbol representing each enemy character (enemy symbol) are arranged in the game field. When the player symbol comes into contact with the enemy symbol, the battle with the enemy character corresponding to the enemy symbol is started. In this battle, an enemy character represented by an enemy symbol encountered with the player character is arranged in a battle field different from the game field. In symbol encounter, there are enemy symbols in the game field, so move the player symbol so that it does not touch the enemy symbol to avoid battle with the enemy character, or conversely, contact the enemy symbol actively. Whether to fight an enemy character, such as a battle, can be selected to some extent by the player's will.

  However, in the conventional symbol encounter, for example, even when there are a plurality of enemy symbols in the vicinity, only the enemy character represented by the enemy symbol that is in contact with the enemy character is fighting. It was not interesting. The present invention has been made in view of the above circumstances, and an object thereof is to improve the interest of a battle with an enemy character in a symbol encounter.

The first invention for solving the above-described problems is
Computer
A PC group display body (for example, the player symbol PS in FIG. 2) representing a player character group (for example, the “player group” in the embodiment) composed of a player character and a teammate character as one display body, and an enemy composed of an enemy character. An image in which a plurality of enemy group display bodies (for example, the enemy symbol ES in FIG. 2) representing a character group (for example, “enemy group” in the embodiment) in one display body is arranged in a predetermined map field is generated. Map scene processing execution means (for example, the map control unit 211 in FIG. 11) for executing the map scene processing
Contact detection means (for example, the map control unit 211 in FIG. 11) for detecting contact between the PC group display body and the enemy group display body in the map scene processing;
A predetermined battle in which the relative positional relationship between the enemy group display body other than the contacted enemy group display body and the PC group display body is a condition of the positional relationship for entering the battle at the time of detection by the contact detection means Extraction means (for example, the map control unit 211 in FIG. 11) that extracts enemy group display bodies that satisfy the entry position relationship condition (for example, the “link condition” in the embodiment);
The player character group, the enemy character group represented by the detected enemy group display body, and the enemy character group represented by the enemy group display body extracted by the extraction means when the detection by the contact detection unit is performed; A battle scene processing execution means (for example, the battle control unit 212 in FIG. 11) for generating an image in which the image is arranged in a predetermined battle field and executing battle scene processing;
As a program (for example, the game program 310 in FIG. 11).

As another invention,
A predetermined map of a PC group display body representing a player character group consisting of a player character and an ally character as a single display body and a plurality of enemy group display bodies representing an enemy character group consisting of an enemy character as a single display body Map scene processing execution means for generating an image arranged in the field and executing map scene processing;
Contact detection means for detecting contact between the PC group display body and the enemy group display body in the map scene processing;
A predetermined battle in which the relative positional relationship between the enemy group display body other than the contacted enemy group display body and the PC group display body is a condition of the positional relationship for entering the battle at the time of detection by the contact detection means Extraction means for extracting enemy group display bodies that satisfy the entry position relation condition;
The player character group, the enemy character group represented by the detected enemy group display body, and the enemy character group represented by the enemy group display body extracted by the extraction means when the detection by the contact detection unit is performed; A battle scene processing execution means for generating an image arranged in a predetermined battle field and executing battle scene processing;
A game device (for example, the game system 1000 in FIG. 11) may be configured.

  According to the first invention and the like, in the map scene processing for generating an image in which a PC group display body and a plurality of enemy group display bodies are arranged in a predetermined map field, the PC group display body and the enemy group display body When contact is detected, an enemy group display body whose relative positional relationship with the PC group display body satisfies a predetermined battle entry position relationship condition is extracted, and the player character group and the enemy represented by the contacted enemy group display body are extracted. A battle scene process for generating an image in which a character group and an enemy character group represented by an enemy group display body that satisfies the battle entry position relationship condition are arranged in a predetermined battle field is performed. Thereby, when the PC group display body and the enemy group display body come into contact with each other in the map field, the battle with the enemy character group represented by the contacted enemy group display body is started. It is possible to realize a new interest with respect to battles with enemy characters, such as a group of enemy characters represented by a group display.

As a second invention, there is provided a program according to the first invention,
A program for causing the computer to function so that the extraction means performs the extraction based on at least the distance and / or relative orientation between the PC group display body and the enemy group display body in the map field. You may do it.

  According to the second aspect of the present invention, the enemy group display body that satisfies the battle entry position relationship condition is extracted based on the distance and / or relative orientation between the PC group display body and the enemy group display body in the map field. Is called. For example, if the distance between the PC group display body and the enemy group display body is not more than a predetermined distance as the battle entry position relationship condition, the PC group display body is not in contact but is present in the vicinity. The effect that the enemy character group of the enemy group display body participates in the battle, or the battle entry position-related condition is approximately in the direction in which the direction of the enemy group display body is directed from the enemy group display body to the PC group display body. If they match, it is possible to produce an effect that the enemy character group of the enemy group display body noticed by the PC group display body enters the battle.

A third invention is a program according to the first or second invention,
When the process shifts from the map scene process to the battle scene process, an identification display unit (for example, FIG. 11) for identifying and displaying the enemy group display body extracted by the extraction unit (for example, the effect EF2 in FIG. 3). A program for causing the computer to function as the map control unit 211) may be configured.

  According to the third aspect of the invention, when the transition from the map scene process to the battle scene process is performed, the enemy group display body extracted as satisfying the battle entry position relation condition is identified and displayed. Thereby, the player can know the presence or absence of the enemy character group that will enter the battle together with the enemy character represented by the enemy group display body that has contacted.

A fourth invention is a program according to any one of the first to third inventions,
The battle entry position-related conditions are set for each of the enemy character groups (for example, the encounter & link condition table 341 in FIG. 21),
The extraction means extracts an enemy group display body that satisfies the battle entry position relation condition using the battle entry position relation condition set for each enemy character group.
As described above, a program for causing the computer to function may be configured.

  According to the fourth aspect of the invention, the enemy group display body that satisfies the battle entry position relationship condition is extracted using the battle entry position relationship condition set for each enemy character group. Thereby, for example, when the distance between the PC group display body and the enemy group display body is equal to or less than a predetermined distance in the battle entry position relation condition, the predetermined distance is changed depending on the enemy character group. It is possible to realize a new interest using the characteristics assumed for the enemy character, such that the enemy character having a high speed enters the battle even if the enemy character is relatively far away.

A fifth invention is a program according to any one of the first to fourth inventions,
A model index value (for example, “model size”) indicating the model size of the character model is set in advance for each enemy character (for example, the enemy character DB 325 in FIG. 13).
The battle scene processing execution means
Appearance that defines the appearance determination order of each enemy character included in the enemy character group represented by the enemy group display body detected by the contact detection means and the enemy character group represented by the enemy group display body extracted by the extraction means Determination order defining means (for example, the battle control unit 212 in FIG. 11),
When an enemy character is selected according to the appearance determination order so that the total index value of enemy characters to appear is less than or equal to a predetermined maximum index total value, and the enemy character becomes unable to battle during the battle scene process The enemy character newly appearing such that the sum of the index value of the appearing enemy character excluding the enemy character that has become impossible to battle and the index value of the enemy character newly appearing is equal to or less than the maximum value of the index total. Enemy character selection means (for example, battle control unit 212 in FIG. 11) to select according to the appearance determination order;
Character placement control means (for example, the battle control unit 212 in FIG. 11) that erases the enemy character that has become incompetent from the battle field and places the enemy character selected by the enemy character selection means in the battle field; ,
Having
As described above, a program for causing the computer to function may be configured.

  According to the fifth aspect of the present invention, in the battle scene, the sum of the model index values indicating the model size of the character model of each enemy character is equal to or less than the predetermined maximum index total value in accordance with the appearance determination order defined for each enemy character. The enemy character appears in the battle field. If an enemy character becomes incompetent during the battle scene process, the inoperable enemy character is erased from the battle field, and the appearing enemies excluding the enemy character that has become incompetent according to the order of appearance. A new enemy character appears in the battle field so that the sum of the model index value of the character and the model index value of the newly appearing enemy character is equal to or less than the maximum index total value. That is, the sum of the model index values of the enemy characters appearing in the battle field is always less than or equal to the predetermined maximum index total value.

  By the way, when a plurality of enemy group display bodies satisfy the battle entry position condition at the time of contact between the PC group display body and the enemy group display body, let all the enemy characters that constitute each of these enemy group display bodies appear simultaneously. Then, the drawing load increases, and for example, there is a possibility that real-time image generation for drawing an image of one frame every 1/60 seconds cannot be performed. In addition, when an enemy character is formed of a polygon model, the drawing load generally increases as the model size increases. However, as in the fifth aspect of the present invention, the enemy characters in the battle scene are not caused to appear at the same time by causing the enemy characters to appear in order based on the model index value indicating the model size. The drawing load of the character can be suppressed below a certain level, and the occurrence of a so-called “processing failure” can be suppressed.

The sixth invention is a program of the fifth invention,
The enemy character represented by the enemy group display body extracted by the extraction means is the appearance determination order of the enemy characters of the enemy character group represented by the enemy group display body detected by the contact detection means. You may comprise the program for functioning the said computer so that it may prescribe | regulate the order | rank priority over the appearance determination order | rank of each enemy character of a group.

  According to the sixth invention, the enemy character group indicated by the enemy group display body in which the appearance determination order of each enemy character of the enemy character group represented by the enemy group display body in contact with the PC group display body satisfies the battle entry position condition The order of priority of the appearance determination order of each enemy character is defined. That is, the enemy character corresponding to the enemy group display body that has come into contact with the PC group display body appears in the battle field earlier than the enemy character corresponding to the enemy group display body that satisfies the battle entry condition.

Further, as a seventh invention, there is provided a program according to the fifth or sixth invention,
For each of the enemy character groups, the formation of each enemy character constituting the enemy character group is set in advance (for example, the enemy character DB 325 in FIG. 13).
Based on the formation set for each enemy character group represented by the enemy group display body detected by the contact detection means and the enemy group display body extracted by the extraction means, the character placement control means Determining an arrangement position of each enemy character constituting the character group in the battle field;
As described above, a program for causing the computer to function may be configured.

  According to the seventh aspect, for each enemy character group, the formation of each enemy character constituting the enemy character group is set in advance, and in the battle scene, based on the formation set for each enemy character group. Then, the arrangement position of each enemy character constituting each enemy character group in the battle field is determined. That is, each enemy character group appears in the battle field in the formation set for the enemy character group.

As an eighth invention, there is provided a program according to the seventh invention,
In the battle field, an enemy character group appearance area is set (for example, an enemy area AR2 in FIG. 7).
As the formation, an appearance position in the appearance area of each enemy character constituting the enemy character group is set in advance (for example, enemy character DB 325 in FIG. 13),
The character placement control means determines the possibility that the character to appear overlaps with another character, and if it is determined that there is a possibility, the character placement control means shifts the position of the character to appear and places it in the battle field.
As described above, a program for causing the computer to function may be configured.

  According to the eighth aspect, the appearance field of the enemy character group is set in the battle field, and the appearance position in the appearance area of each enemy character constituting the enemy character group is formed as the formation of each character group. Is preset. When there is a possibility that a character to appear overlaps with another character, the character to be caused to appear is shifted in the battle field. That is, it is determined that whenever an enemy character appears in the battle field, it always appears at the appearance position determined for the enemy character in the appearance area. By the way, in the battle scene, there is a possibility that another character already exists at the appearance position of a new enemy character as each character moves freely, and a new enemy character appears overlapping this character. Such an unnatural state may occur. However, as in the eighth aspect of the invention, when a new enemy character appears in the battle field, the possibility of overlapping with other characters appearing in the battle field is determined. By shifting the appearance positions of the enemy characters, the unnatural appearance of overlapping with the other characters described above can be avoided.

Further, as a ninth invention, there is provided a program according to any one of the fifth to eighth inventions,
The battle field is set by dividing the appearance area of the player character group and the appearance area of the enemy character group (for example, the player area AR1 and the enemy area AR2 in FIG. 7).
The contact detection means includes a relative direction determination means for determining a relative direction between the PC group display body and the enemy group display body at the time of contact;
When the character placement control means places each of the characters constituting the player character group in the appearance area of the play character group at the start of the battle scene process, the enemy placement control unit determines whether the enemy orientation is in accordance with the determination result of the relative direction determination unit. PC group placement control means for switching between placement in the forward direction or formation in the reverse direction with respect to the appearance region of the character group,
A program may be configured.

  According to the ninth aspect of the invention, the battle field is set by dividing the appearance area of the player character group and the appearance area of the enemy character group, and each character constituting the player character group is set at the start of the battle scene process. When placing in the appearance area, depending on the determination result of the relative orientation of the PC group display body and the enemy group display body at the time of contact, it is arranged in a forward formation with respect to the appearance area of the enemy character group, or vice versa It is arranged by switching whether to arrange in the formation of the direction. In general, when the player character group is arranged in the reverse formation, it is often disadvantageous in the battle compared to the case where it is arranged in the forward formation. As a result, the arrangement direction of the formation when the player character group appears in the battle field differs depending on the relative orientation when the PC group display body and the enemy group display body contact each other in the map field, and this affects the battle. A new interest in combating enemy characters, such as giving, can be realized.

The tenth invention is a program according to the seventh invention,
The map of the detected enemy group display body and the enemy group display body extracted by the extraction means with respect to the PC group display body when the character placement control means is detected by the contact detection means According to the relative positional relationship in the field, the formation position in the battle field of each enemy character group represented by each enemy group display body is determined, and the enemy character selected by the enemy character selection means is determined based on the determined formation position. Placing it in the battle field,
As described above, a program for causing the computer to function may be configured.

  According to the tenth invention, when the PC group display body and the enemy group display body are in contact, the contacted enemy group display body with respect to the PC group display body and the enemy group display body satisfying the battle entry position condition According to the relative positional relationship in the map field, the formation position in the battle field of each enemy character group represented by each enemy group display is determined, and each enemy character is arranged in the battle field based on the determined formation position. The relationship between the relative formation positions of the player character group and each enemy character group in the battle field greatly affects the battle. Thus, in the map field, the player character group and each corresponding enemy character according to the relative positional relationship between the PC group display body and each enemy group display body when the PC group display body and the enemy group display body contact each other. The formation position in the battle field of the group is different, and this can influence the battle, and a new interest for the battle with the enemy character can be realized.

An eleventh invention is a program according to the tenth invention,
The character placement control means determines the possibility that the character to appear overlaps with another character, and if it is determined that there is a possibility, the character placement control means shifts the position of the character to appear and places it in the battle field.
As described above, a program may be configured to cause the computer to function.

  According to the eleventh aspect, when there is a possibility that a character to appear overlaps with another character, the position of the character to appear is shifted in the battle field. In the battle scene, there is a possibility that another character already exists at the appearance position of the new enemy character as each character moves freely, and the new enemy character overlaps with the existing character. An unnatural state of appearance may occur. However, as in the eleventh aspect, when a new enemy character appears in the battle field, the possibility of overlapping with another character appearing in the battle field is determined. By shifting the appearance positions of the enemy characters, the unnatural appearance of overlapping with the other characters described above can be avoided.

  As a twelfth invention, a computer-readable information storage medium (for example, the storage unit 300 in FIG. 11) storing the program of any one of the first to eleventh inventions may be configured.

  Here, the information storage medium is a storage medium such as a hard disk, an MO, a CD-ROM, a DVD, a memory card, or an IC memory that can be read by a computer. Therefore, according to the twelfth aspect, the same effect as any one of the first to eleventh aspects can be obtained by causing the computer to read the information stored in the information storage medium and executing the arithmetic processing. be able to.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following, the case where the present invention is applied to a home game system that executes RPG will be described, but embodiments to which the present invention can be applied are not limited thereto.

[appearance]
FIG. 1 is a diagram showing an example of the appearance of a home game system 1000 according to the present embodiment. As shown in the figure, the game system 1000 includes a main device 1100, a game controller 1200 for a player to input a game operation, and a video monitor 1300 having a display 1302 and a speaker 1304.

  Game information including programs and data necessary for the main apparatus 1100 to perform game processing is stored in, for example, an optical disk 1122 or a memory card 1124 which is an information storage medium detachable from the main apparatus 1100. That is, the player can enjoy different games by exchanging the optical disk 1122 and the like. The game information may be downloaded and acquired from an external device by connecting to the communication line N via the communication device 1112 included in the main device 1100. Here, the communication line N means a communication path through which data can be exchanged. That is, the communication line N includes not only a dedicated line (dedicated cable) for direct connection, a LAN (Local Area Network) by Ethernet (registered trademark), but also a communication network such as a telephone communication network, a cable network, and the Internet. This means that the communication method may be wired or wireless.

  The main unit 1100 also includes a control unit 1110 on which, for example, a CPU, an image processing LSI, an IC memory, and the like are mounted, and information storage medium reading devices 1102 and 1104 such as an optical disk 1122 and a memory card 1124. The CPU mounted on the control unit 1110 executes various game operations based on game information read from the optical disk 1122 and the memory card 1124, operation signals from the game controller 1200, and the like, and image signals of the game screen are displayed. And a sound signal of the game sound is generated to execute a given video game. The generated game image and game sound are output to the video monitor 1300 via a signal cable 1108 capable of transmitting an image signal and a sound signal. The player enjoys the game by operating the game controller 1200 while watching the game image displayed on the display 1302 of the video monitor 1300 and listening to the game sound such as BGM and sound effect output from the speaker 1304.

[principle]
In the RPG of this embodiment, when the player character encounters an enemy character while moving in the map field (map space), the movement in the map field is interrupted and the player character moves to the battle field (battle space). The battle begins.

  FIG. 2 is a diagram illustrating an example of the map screen. As shown in the figure, in the map field, one player symbol PS that is a PC group display body and one or more enemy symbols ES that are enemy group display bodies are arranged. The player symbol PS is a symbol representing a player group composed of player characters and teammate characters, and moves in the map field in accordance with player operation instructions. The enemy symbol ES is a symbol representing an enemy group composed of one or a plurality of enemy characters, and moves in the map field by computer control. Here, the ally character and the enemy character are computer-controlled NPCs (non-player characters).

  The enemy symbol ES is usually wandering the map field, but when the player symbol PS is found, the enemy symbol ES increases in speed and approaches the player symbol PS. When the player symbol PS comes into contact with the enemy symbol ES, the player symbol PS shifts to a battle because it has “encountered” the enemy group represented by the enemy symbol ES. At this time, if an enemy symbol ES that is different from the encountered enemy symbol ES is near the player symbol PS, it is assumed that the enemy group represented by the enemy symbol ES is “linked” and this enemy group also enters the battle.

  FIG. 3 is a diagram showing a map screen at the time of encounter between the player symbol PS and the enemy symbol ES. In the figure, the player symbol PS encounters the enemy symbol ES1 and is linked to the enemy symbol ES2. Then, an effect EF1 indicating that it has encountered is displayed between the encountered enemy symbol ES1, and an effect EF2 indicating that it has been linked is displayed between the enemy symbol ES2 that has been linked. . With these effects EF1 and EF2, the player can grasp the enemy symbol ES encountered and the linked enemy symbol ES. As an identification display of the enemy symbol ES that has been encountered and linked, for example, a predetermined effect may be applied to the enemy symbol ES itself.

  FIG. 4 is a diagram for explaining “encounter” and “link” between a player symbol and an enemy symbol. As shown in the figure, in the map field, when the relative positional relationship between the player symbol PS and the enemy symbol ES satisfies a predetermined “encounter condition”, the player symbol PS “encounters” the enemy symbol ES. Determined. Here, the “encounter condition” is that the distance D between the player symbol PS and the enemy symbol ES is equal to or less than a predetermined distance Da that is considered to be in contact with each other. In the figure, it is determined that the player symbol PS has encountered the enemy symbol ES1.

  Further, when the player symbol PS encounters an enemy symbol ES, if there is an enemy symbol ES other than the encountered enemy symbol ES and whose relative positional relationship with the player symbol PS satisfies a predetermined “link condition”, It is determined that the enemy symbol ES is “linked”. Here, the “link condition” is that the distance D between the player symbol PS and the enemy symbol ES is equal to or less than the predetermined distance Db. However, Da <Db. In the figure, it is determined that the player symbol PS is “linked” to the enemy symbols ES2 and ES3.

  FIG. 5 is a diagram illustrating an example of a battle screen. As shown in the figure, on the battle screen, in the battle field, a player team composed of the player character PC and the teammate character AC and an enemy group composed of one or more enemy characters EC are displayed facing each other. The figure shows a case where an enemy group A consisting of three enemy characters ECa and an enemy group B consisting of three enemy characters ECb are played.

  In the present embodiment, in the battle field, not all of the enemy characters that will compete will appear at once, but some or all of them will appear so as to satisfy a predetermined “appearance condition”.

  FIG. 6 is a diagram illustrating the appearance of a character in the battle field. The figure shows a case in which a battle between an “encountered” enemy group A and two “linked” enemy groups B and C is entered. The enemy group A is composed of two enemy characters a1 and a2, the enemy group B is composed of three enemy characters b1, b2 and b3, and the enemy group C is composed of two enemy characters c1 and c2. Composed. That is, a total of seven enemy characters will be played.

  As shown in FIG. 5A, first, the appearance priority order (appearance determination order) in the battle field is determined for each enemy character to fight. The enemy character of the enemy group of the encountered enemy symbol is the highest in appearance priority, and then the enemy group having a short (near) distance D to the player symbol PS at the time of linking among the enemy groups of the linked enemy symbols. It becomes higher in order from the enemy character. Further, the appearance priority order of enemy characters in the same enemy group is set to a predetermined order within the group. In the figure, the appearance priority of the enemy characters a1 and a2 of the encountered enemy symbol A is the highest, followed by the enemy characters b1 to b3 of the linked enemy symbol B and then the enemy characters c1 to c3 of the enemy symbol C. ing.

  Next, an enemy character that appears to satisfy the “appearance condition” is determined for each enemy character to be battled according to the predetermined appearance priority order. Here, the “appearance condition” is that the sum of drawing costs of each enemy character that appears (appears) in the battle field does not exceed a predetermined cost upper limit. The enemy character is formed by a polygon model, and a “drawing cost” corresponding to the size is determined as the model size of the polygon model. There are four types of model sizes of enemy characters, S, M, L, and LL, in ascending order, and 1, 3, 8, and 12 are determined as drawing costs for each model size. Then, the character that appears first is determined according to the appearance priority order so that the drawing cost corresponding to each model size does not exceed the predetermined cost upper limit among the enemy characters that compete. In the figure, enemy characters a1, a2, b1, and b3 are enemy characters that first appear in the battle field. The sum of the drawing costs of these enemy characters is “19” and does not exceed the cost upper limit “20”.

  When the enemy character that appears first is determined, the determined enemy character appears in the battle field, and the battle with the player team is started. When the enemy character becomes incapable of fighting during the battle, the enemy character that has become incompetent is erased from the battle field, and a new enemy character that has not appeared appears. Also at this time, an enemy character that newly appears is determined according to a predetermined priority order so as to satisfy the appearance condition. That is, the sum of the drawing costs of the enemy character appearing in the battle field and the newly appearing enemy character when newly appearing in the battle field in accordance with the priority appearance order among the non-appearing enemy characters is An enemy character that does not exceed the upper limit of the cost is selected and set as a newly appearing enemy character.

  For example, as shown in FIG. 5B, when the enemy character a2 becomes unable to battle, the sum of the drawing costs of the enemy characters appearing in the battle field decreases from “19” to “7”. Then, among the enemy characters that have not yet appeared, enemy characters b2 and c1 newly appear. In this case, the sum of the drawing costs of the enemy characters appearing in the battle field is “18” and does not exceed the cost upper limit “20”.

  FIG. 7 is a diagram illustrating an example of a battle field. As shown in the figure, a player area AR1 and an enemy area AR2 that do not overlap each other are formed in the battle field. The player area AR1 and the enemy area AR2 are three-dimensional spaces extending upward (Yw axis positive direction) from the ground surface. At the start of the battle, the player group is arranged in the player area AR1, and the enemy group is arranged in the enemy area AR2. The player group and the enemy group are arranged so as to face each other. Note that the player area AR1 and the enemy area AR2 determine the position (appearance position) when the character appears in the battle field, and are not limited to this during the battle. An image of this battle field viewed from a given virtual camera CM is displayed as a battle screen.

  Further, the player team and the enemy group appear in a formation determined for each group. “Form” refers to the relative positional relationship of each character. FIG. 8 is a diagram illustrating an example of a formation. In the figure, a formation of a group composed of three characters CR1, CR2 and CR3 is shown. The formation is formed so that the characters CR do not overlap each other in a predetermined formation area AR3 corresponding to the player area AR1 or the enemy area AR2 in the battle field. Here, “characters do not overlap” means that the boundary boxes of the characters CR do not overlap. Further, each character CR is arranged to face the same direction, and the direction of each character CR becomes the “direction” of the formation.

  Then, when this group is arranged in the battle field, as shown in FIG. 9, the formation direction is directed to the opponent group, and the formation area AR3 of the group is arranged in accordance with the corresponding area of the battle field. . That is, the player group is arranged in the player area AR1 with the formation direction directed toward the enemy area AR2, and the enemy group is arranged in the enemy area AR2 with the formation direction directed toward the player area AR1. . The position of each character in the battle field is transformed from the position expressed in the local coordinate system (Xg, Yg, Zg) that defines the formation to the world coordinate system (Xw, Yw, Zw) that defines the battle field. To be given.

  By the way, when a link occurs and a plurality of enemy groups appear at the same time, enemy characters of different enemy groups may overlap at the time of appearance. In this case, of the overlapping enemy characters, the appearance position of the enemy character with the lower appearance priority is shifted so as not to overlap with the other enemy characters.

  FIG. 10 shows a case where a plurality of enemy groups appear. In the figure, a case where two enemy groups A and B appear is shown. The enemy group A is an enemy group that has been encountered, and is composed of three enemy characters ECa1, ECa2, and ECa3. The enemy group B is a linked enemy group and is composed of two enemy characters ECb1 and ECb2. That is, the appearance priority of the enemy characters ECa1, ECa2, and ECa3 of the enemy group A is higher than the enemy characters ECb1 and ECb2 of the enemy group B. FIG. 5A shows the formation of the enemy group A. Further, FIG. 4B shows the formation of the enemy group B. FIG. 6C shows a case where the enemy groups A and B appear simultaneously. As shown in FIG. 5C, the enemy character ECa1 and the enemy character ECb1 overlap each other. In this case, the appearance position of the enemy character ECb1 with the lower priority appearance order is changed so as to be shifted diagonally backward, for example, so as not to overlap with the other enemy characters ECa1, ECa2, ECa3, ECb2.

[Function configuration]
FIG. 11 is a block diagram showing a functional configuration of the game system 1000. According to the figure, the game system 1000 functionally includes an operation input unit 110, a processing unit 200, an image display unit 120, a sound output unit 130, a communication unit 140, and a storage unit 300. Configured.

  The operation input unit 110 receives an operation input by the player and outputs an operation signal corresponding to the operation to the processing unit 200. This function is realized by, for example, a button switch, lever, mouse, keyboard, various sensors, or the like. In FIG. 1, the game controller 1200 corresponds to this.

  The processing unit 200 performs various arithmetic processes such as overall control of the game system 1000, game progress, and image generation based on programs and data read from the storage unit 300, operation signals input from the operation input unit 110, and the like. This function is realized, for example, by an arithmetic device such as a CPU (CISC type or RISC type), ASIC (gate array, etc.) or a control program thereof. In FIG. 1, the CPU mounted on the control unit 1110 corresponds to this. The processing unit 200 includes a game calculation unit 210 that mainly performs calculation processing related to game execution, an image generation unit 220 that generates a game image based on data obtained by the processing of the game calculation unit 210, and sound effects. And a sound generator 230 for generating game sounds such as BGM.

  The game calculation unit 210 includes a map control unit 211 and a battle control unit 212, and executes game processing according to the game program 310. Here, data on the player group appearing in the game is stored in the player group data 321, and data on the enemy group is stored in the enemy character DB 325.

  FIG. 12 is a diagram showing an example of the data structure of the player group data 321. As shown in FIG. According to the figure, the player group data 321 stores a symbol ID 321a of a player symbol PS representing a player group, player character data 322, and teammate character data 323. The player character data 322 stores a character ID 322a and a character name 322b of the player character, a physical strength value 322c as an ability parameter, an attack power 322d and a defense power 322e, a model data ID 322f, a boundary box 322g, and a formation position 322h. doing. The boundary box 322g is the length (Lx, Ly, Lz) of each side along the Xg, Yg, and Zg axes in the local coordinate system of the boundary box of the player character. The formation position 322h is the position of the player character in the formation of the player group, and is position coordinates (x, y, z) expressed in the local coordinate system. The formation of the player group can be changed according to the player's operation instruction. The teammate character data 323 includes a character ID 323a and a character name 323b, a physical strength value 323c, an attack power 323d and a defense power 323e, a model data ID 323f, a boundary box 323g, a formation position 323h, and the like for each teammate character. Are stored in association with each other.

  FIG. 13 is a diagram illustrating an example of a data configuration of the enemy character DB 325. According to the figure, the enemy character DB 325 is composed of a plurality of enemy group data 326 for each enemy group. The enemy group data 326 stores the group ID 326a of the corresponding enemy group and the symbol ID 326b of the enemy symbol ES, and the ability value 326d and the attack power 326e, which are ability parameters, for each enemy character 326c of the enemy group. The defensive power 326f, the model data ID 326g, the model size 326h, the boundary box 326i, and the formation position 326j are stored in association with each other. The boundary box 326i is the length of each side of the boundary box of the enemy character, and is expressed in the local coordinate system. The formation position 326j is the position of the enemy character in the formation of the enemy group, and is expressed in the local coordinate system.

  The map control unit 211 constructs a map field and controls the player symbol PS and enemy symbol ES in this map field. The player symbol PS is controlled according to a player operation instruction input from the operation input unit 110, and the enemy symbol ES is controlled according to a control routine determined according to the type of the enemy symbol ES.

  Further, the encounter and link between the player symbol PS and the enemy symbol ES are determined in the map field. That is, the distance D between the player symbol PS and the enemy symbol ES is monitored, and when the distance D is equal to or less than the distance Da which is an encounter condition, it is determined that the corresponding enemy symbol ES has been encountered. At this time, an enemy symbol ES whose distance D to the player symbol PS is equal to or less than the distance Db which is the link condition is extracted from enemy symbols ES different from the encountered enemy symbol ES. Judge that linked. Here, the encounter condition is stored in the encounter condition data 333, and the link condition is stored in the link condition data 334.

  The battle control unit 212 controls a battle between the player team and an enemy group corresponding to the enemy symbol ES determined to be encountered and linked by the map control unit 211. Specifically, first, an enemy group corresponding to each enemy symbol ES encountered and linked with reference to the enemy character DB 325 is determined, and an enemy character (opposing enemy character) that battles the enemy characters that make up this enemy group To do. Next, the appearance priority of these opponent characters is determined. That is, the appearance priority order of the enemy characters of the enemy group encountered is made highest, and then the appearance priority of each enemy character of the enemy group in the order of the shortest distance D to the player symbol at the time of linking among the linked enemy groups. Increase the ranking.

  Data on enemy characters (competing enemy characters) that compete in the battle are stored in the opponent character list 332. FIG. 14 is a diagram illustrating an example of a data configuration of the battle enemy character list 332. According to the figure, the opponent enemy character list 332 stores the health value 332c of each enemy character 332b, the drawing cost 332d, the appearance flag 332e, and the current position 332f in association with the appearance priority 332a. ing. The drawing cost 332d is determined by the model size of the corresponding enemy character. The drawing cost for each model size is defined in the cost table 331. The appearance flag 332e is a flag indicating whether or not the corresponding enemy character has appeared in the battle field. The current position 332f is the current arrangement position of the corresponding enemy character in the battle field, and is expressed in the world coordinate system (Xw, Yw, Zw) that defines the battle field.

  FIG. 15 is a diagram illustrating an example of a data configuration of the cost table 331. According to the figure, the cost table 331 stores the drawing cost 331b in association with each model size 331a.

  Subsequently, the battle control unit 212 determines an enemy character that first appears in the battle field so as to satisfy the appearance condition from among the battle enemy characters. In other words, according to the appearance priority order, the enemy character is selected and caused to appear so that the sum of the drawing costs according to the model size of each enemy character does not exceed a predetermined cost upper limit. Here, the appearance condition is stored in the appearance condition data 335.

  Next, the appearance position in the battle field of each enemy character determined to appear first is determined. That is, the formation position expressed in the local coordinate system is converted into a world coordinate system that defines the battle field, and is set as an appearance position in the enemy area AR2 of the battle field. At this time, if there are enemy characters whose appearance positions overlap, the appearance positions of the enemy characters having lower appearance priority among the overlapping enemy characters are shifted and changed so as not to overlap with other enemy characters. Then, these enemy characters are arranged at the determined appearance positions in the battle field.

  Similarly, in the player group, the player character and the teammate character are arranged in a formation defined in the player area AR1 of the battle field.

  Thereafter, the battle between the player group and the enemy group is started. In battle, the player character is controlled according to a player operation instruction input from the operation input unit 110, and the other NPCs (friend character and enemy character) are controlled according to a predetermined control routine.

  When the enemy character becomes unable to battle during the battle, the battle control unit 212 deletes the enemy character from the battle field. Then, an enemy character to be newly appeared is determined so as to satisfy the appearance condition among the non-appearing opponent characters. That is, the sum of the drawing cost of each enemy character that is appearing and the drawing cost of an enemy character that is newly appearing does not exceed a predetermined cost upper limit in accordance with the determined priority of appearance from the non-appearing opponent characters. Select an enemy character. Then, the position in the formation of the corresponding enemy group determined for the selected enemy character is set as the appearance position of the enemy character. At this time, when the appearance position overlaps with another character (enemy character, player character, or teammate character) already existing in the battle field, the appearance position is changed to a position that does not overlap with another character.

  Then, when either the player group or all enemy groups are disabled, the battle is terminated. The victory or defeat of the battle is the victory of the player if the enemy characters of all enemy groups become incompetent, and conversely the defeat of the player if all of the characters in the player group become incompetent.

  Returning to FIG. 11, the image display unit 120 displays the game screen while redrawing an image of one frame every 1/60 seconds, for example, based on the image signal from the image generation unit 220. This function is realized by, for example, a CRT, LCD, ELD, PDP, or the like. In FIG. 1, the display 1302 corresponds to this.

  The sound output unit 130 outputs game sounds such as BGM and sound effects based on the sound signal from the sound generation unit 230. This function is realized by a speaker, for example. In FIG. 1, the speaker 1304 corresponds to this.

  The communication unit 140 is connected to the communication line N according to a control signal from the processing unit 200 and performs data communication with an external device. This function is realized by a wireless communication module, TA, router, wired communication cable jack, control circuit, and the like. In FIG. 1, the communication device 1112 corresponds to this.

  The storage unit 300 stores a system program for realizing various functions for causing the processing unit 200 to control the game system 1000 in an integrated manner, a program and data necessary for executing the game, and the like. It is used as a work area, and temporarily stores calculation results executed by the processing unit 200 according to various programs, input data from the operation input unit 110, and the like. This function is realized by, for example, various IC memories, hard disks, MO, RAM, CD-ROM, DVD, and the like. In FIG. 1, an IC memory, an optical disk 1122 and a memory card 1124 mounted on the control unit 1110 correspond to this. In the present embodiment, a game program 310 is stored as a program in the storage unit 300, and player group data 321, enemy character DB 325, cost table 331, opponent enemy character list 332, encounter as data Condition data 333, link condition data 334, and appearance condition data 335 are stored.

[Process flow]
FIG. 16 is a flowchart of the game process. According to the figure, first, the map control unit 211 performs map processing (map scene processing). In this map processing, the map control unit 211 arranges a player symbol and a plurality of enemy symbols in the map field, controls the player symbols according to the player's operation instructions, and controls each enemy symbol according to a predetermined control routine (step). A1).

  Further, the distance D between the player symbol and the enemy symbol is monitored to determine whether there is an enemy symbol that satisfies the encounter condition. If there is an enemy symbol that satisfies the encounter condition (step A3: YES), it is further determined whether there is an enemy symbol that satisfies the link condition when the encounter condition is satisfied.

  If there is an enemy symbol that satisfies the link condition (step A5: YES), after performing a predetermined encounter & link effect (step A7), the battle control unit 212 performs a battle process (see FIG. 17) (step A11). . Here, as the encounter & link effect processing, for example, a predetermined effect EF1 is displayed between the player symbol PS and the encountered enemy symbol ES as shown in the map screen of FIG. 3, and the enemy symbol linked to the player symbol PS is displayed. There is a process of displaying a predetermined effect EF2 between each ES and a process of outputting a predetermined sound in accordance with this display.

  On the other hand, if there is no enemy symbol that satisfies the link condition (step A5: NO), after performing a predetermined encounter effect (step A9), the battle control unit 212 performs a battle process (see FIG. 17) (step A11). . Here, as the encounter effect, for example, as shown in the map screen of FIG. 3, a process of displaying a predetermined effect EF1 between the player symbol PS and the encountered enemy symbol ES, or a predetermined audio output in accordance with this display There is a process to do.

  In addition, when the player is instructed to change the formation (step A13: YES), the game calculation unit 210 performs a change process of the formation of the player group in accordance with the operation instruction of the player (step A15). Subsequently, it is determined whether or not to end the game. If not ended (step A17: NO), the process returns to step A1. If completed (step A17: YES), the game process is terminated.

  FIG. 17 is a flowchart for explaining the battle process. According to the figure, first, the enemy characters of the enemy group representing each of the encountered enemy symbols and the linked enemy symbols are set as enemy characters (competing enemy characters) that compete in the battle. Next, the appearance priority of these opponent characters is determined (step B1). That is, the appearance priority of the enemy character of the enemy group of the encountered enemy symbol is made the highest, and then the appearance priority of the enemy character is set in the order of the shortest distance D from the linked player symbol to the player symbol at the time of linking. Make it high.

  Subsequently, an enemy character that first appears in the battle field is determined from the opponent characters (step B3). That is, an enemy character is selected from the opponent enemy characters in accordance with the appearance priority order so that the sum of drawing costs of the enemy characters does not exceed a predetermined cost upper limit, and is set as the first enemy character to appear. Then, for each enemy character determined to appear, the position of the enemy character in the formation of the corresponding enemy group is set as the appearance position in the battle field (step B5). As a result, it is determined whether there is an enemy character that overlaps with each other. If there is an enemy character (step B7: YES), the appearance position of the enemy character with the lower appearance priority of this overlapping enemy character does not overlap with other characters. (Step B9). Then, these enemy characters are arranged at the determined appearance position and appear in the battle field (step B11).

  Thereafter, attack control of each character is performed (step B13). That is, the player character is controlled according to the player's operation instruction, and the other NPCs (friend character and enemy character) are controlled according to a predetermined control routine.

  As a result, if the enemy character becomes unable to fight (step B15: YES), the enemy character that becomes impossible to fight is deleted. Further, it is determined whether there is an enemy character that has not yet appeared. If there is an enemy character that has not yet appeared (step B17: YES), an enemy character that is to appear next is determined from the enemy characters that have not yet appeared. (Step B19). In other words, new appearances are made so that the sum of the drawing cost of each of the appearing enemy characters and the drawing cost of the newly appearing enemy character does not exceed a predetermined cost upper limit among the non-appearing enemy characters. Select the enemy character to be activated.

  Next, for the determined enemy character, the position of the enemy character in the formation of the corresponding enemy group is set as the appearance position in the battle field (step B21). Subsequently, it is determined whether or not the enemy character overlaps with another character already placed in the battle field by placing the enemy character in the battle field. If it overlaps with another character (step B23: YES), The appearance position of the enemy character is changed to a position that does not overlap other characters (step B25). Then, this enemy character is placed at the determined appearance position and newly appears in the battle field (step B27).

  Further, the battle control unit 212 determines whether or not the battle has ended as a result of the attack processing of each character. If not ended (step B29: NO), the battle control unit 212 returns to step B15 and repeats the same processing. If the battle is completed (step B29: YES), the battle process is terminated.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can of course be changed as appropriate without departing from the spirit of the present invention.

(A) Appearance of each group in the battle field For example, in the above-described embodiment, when a player group and an enemy group appear in the battle field, they appear in a predetermined area so as to face each other. This may be caused to appear in a direction corresponding to the relative positional relationship between the symbols when the player symbol and the enemy symbol are encountered in the map field. At this time, the “direction” is determined for each of the player symbol and the enemy symbol. This “direction” may be a direction in which the body or face of the symbol is facing, or may be a moving direction.

(A-1)
For example, the relative positional relationship between the player symbol and the enemy symbol at the time of encounter is maintained in the battle field. Specifically, FIG. 18A shows the positional relationship at the time of encounter between the player symbol PS and the enemy symbol ES in the map field. In FIG. 5A, the player symbol PS encounters the enemy symbol ES1 and is linked to the enemy symbol ES2. The relative positional relationship between the player symbol PS and the enemy symbols ES1 and ES2 is as follows. That is, when the position and orientation of the player symbol PS are used as a reference, the enemy symbol ES1 is located “leftward” of the player symbol, and its orientation is “rightward”. Further, the enemy symbol ES1 is located “right front” of the player symbol PS, and its direction is “left rear”. The relative positional relationship at the time of encounter between symbols in this map field is used as it is as the relative positional relationship at the time of appearance of each group corresponding to the symbol in the battle field.

  FIG. 4B shows the positional relationship when each group corresponding to each symbol in FIG. In FIG. 6B, the relative positional relationship between the player group PG and each enemy group EG1, EG2 is maintained while maintaining the relative relationship between the player symbol PS and the enemy symbols ES1, ES2 in FIG. Yes. That is, when the position of the player group PG and the direction of the formation thereof are used as a reference, the enemy group EG1 is positioned “leftward” of the player group PG, and the direction of the formation of the enemy group EG1 is “rightward”. Further, the enemy group EG2 is positioned “right front” of the player group PG, and the direction of the enemy group EG2 is “left rear”. Note that the distance between groups in the battle field may be fixed regardless of the distance D between symbols in the map field, or the distance between groups in the battle field according to the distance D between symbols in the map field. May be variable.

(A-2)
Further, when the relative positional relationship between the player symbol PS and the enemy symbol ES in the map field is a predetermined positional relationship, the formation direction at the time of appearance of the player group may be the reverse direction from the normal direction. good.

  For example, FIG. 19A shows a positional relationship when the player symbol PS and the enemy symbol ES are encountered in the map field. In FIG. 5A, the player symbol PS is in contact with the enemy symbol ES “behind (backward)”. In such a case, the direction of the formation when the player group PG appears in the battle field is opposite to the normal direction, as shown in FIG. In other words, the enemy group EG is arranged with the direction of the formation facing the player group PG, and the player group PG is arranged with the direction of the formation facing the opposite direction to the enemy group EG.

(B) Link condition In the above-described embodiment, the link condition is “the distance D between the player symbol PS and the enemy symbol ES is equal to or less than the predetermined distance Db”, but further includes the condition of the symbol direction. It is also good. For example, the link condition is “the distance D between the player symbol PS and the enemy symbol ES is equal to or less than the predetermined distance Db, and the direction of the enemy symbol ES faces the player symbol PS”. Here, whether the enemy symbol ES faces the player symbol PS is determined as follows. That is, as shown in FIG. 20, if the angle θ formed by the direction of the enemy symbol ES and the direction from the enemy symbol ES toward the player symbol PS is equal to or smaller than a predetermined angle, the enemy symbol ES is the player symbol PS. It is considered to be facing. In this way, it is possible to realize processing as if the enemy symbol ES has a virtual field of view.

(C) Encounter condition and link condition The encounter condition and link condition may be different for each enemy symbol. Specifically, for example, the encounter condition 341b and the link condition 341c are defined in association with each other for each enemy symbol 341a as in the encounter & link condition table 341 of FIG. In the map field, it is determined whether the distance D between the player symbol PS and the enemy symbol ES satisfies the encounter condition or link condition of the enemy symbol ES.

(D) Game Device In the above-described embodiment, the case where the present invention is applied to a home game system has been described. However, the present invention may be any type of game device such as a business game device or a portable game device. May be.
