Description

This invention relates to a program you and game system in which the player character that the player is operated to perform a game of action games, etc. to subdue the enemy character continue to clear the mission.

There is a hunting action game as a game that is currently popular with many people.
In the hunting action game, the game progresses when the player character operated by the player subjugates a monster that is an enemy character.

  A physical strength value that is a parameter indicating the vitality is set for the monster. The physical strength value decreases only by receiving an attack from the player character, and does not decrease depending on the behavior of the monster itself. When the health value reaches 0, the monster is killed and subjugated. The monster's behavior did not change with the increase or decrease of the health value, and the monster continued to perform the same behavior until the death, no matter how much the health value decreased.

"Monster Hunter Portable 2nd Official Guidebook" Enterbrain Corporation, July 18, 2007, p.102-108

  However, if the monster continues fighting with constant momentum until death during the battle with the player character, the battle situation does not change, and the player cannot perform a strategic battle. That is, the phenomenon assumed in the actual battle that the power of the monster's fighting action is weakened by the action of the monster itself was not included in the game.

  Therefore, a method is conceivable in which the physical strength value is decreased by the behavior of the monster itself, and the behavior pattern is changed accordingly. However, since the physical strength value is a parameter related to the life and death of the monster, it should not be easily increased or decreased, and should not be decreased except when the player character is attacked.

  Therefore, apart from the physical strength value, it can be easily increased or decreased by the behavior of the monster itself, and it is necessary to newly provide a parameter indicating whether or not the monster is healthy. Also, by changing this parameter, it was necessary to slow down the action power regardless of the monster's vitality.

An optical disk 4 which is an example of a replaceable storage medium is set in the game apparatus 10, and a removable memory card 5 for storing game save data and the like in a non-volatile manner is mounted as necessary. The game apparatus 10 is provided with a power ON / OFF switch that is a main power source of the game and an eject switch for attaching and detaching the optical disk 4.

  The controller 7 is an apparatus that is operated by a player and transmits an operation signal indicating the operation content to the game apparatus 10. The game apparatus 10 performs control such as starting and ending the game in accordance with the operation signal transmitted from the controller 7 and advancing the game. Communication between the controller 7 and the game apparatus 10 is performed wirelessly. As a communication unit for this communication, the controller 7 includes a communication unit 75 (see FIG. 4), and the game apparatus 10 includes a receiving unit 36a (see FIG. 2). One to four controllers 7 can be wirelessly connected to one game apparatus 10.

  Light emitting units 8L and 8R are attached to the left and right upper surfaces of the monitor device 9 to inform the controller 7 of the position of the monitor device 9. The light emitting units 8L and 8R each incorporate an infrared LED, and emit light with infrared rays while the game apparatus 10 is in operation.

  Next, the functional configuration of the game apparatus 10 will be described with reference to the block diagram of FIG. In FIG. 2, the game apparatus 10 includes a CPU (Central Processing Unit) 30 that executes various programs. The CPU 30 executes a boot program stored in a boot ROM (not shown), initializes a memory such as the main memory 33, and the like, and then executes a game program stored in the optical disc 4 according to the game program. Game processing and the like. A GPU (Graphics Processing Unit) 32, a main memory 33, a DSP (Digital Signal Processor) 34, and an ARAM (Audio RAM) 35 are connected to the CPU 30 via a memory controller 31. In addition, a controller I / F (interface) 36, a video I / F 37, an external memory I / F 38, an audio I / F 39, and a disk I / F 41 are connected to the memory controller 31 via a predetermined bus 42. The receiving unit 36a, the monitor device 9, the external memory card 5, the speaker 9a, and the disk drive 40 are connected to each other.

  The GPU 32 performs image processing based on a command from the CPU 30, and is configured by a semiconductor chip that performs calculation processing necessary for displaying 3D graphics, for example. The GPU 32 generates an image of each frame (two-dimensional image by a known perspective projection method) in a three-dimensional virtual space (game space) using a memory dedicated to image processing (not shown) and a partial storage area of the main memory 33. Then, a game image generated by combining an image such as a cursor with this image is output to the monitor device 9 (display 9b) via the memory controller 31 and the video I / F 37. The main memory 33 is a storage area used by the CPU 30 and appropriately stores a game program read from the optical disc 4 and various data.

  The DSP 34 processes sound data generated by the CPU 30 when the game program is executed, and is connected to an ARAM 35 for storing the sound data. The ARAM 35 is used when the DSP 34 performs a predetermined process (for example, storage of a pre-read game program or sound data). The DSP 34 reads the sound data stored in the ARAM 35 and outputs the sound data to the speaker 9 a provided in the monitor device 9 via the memory controller 31 and the audio I / F 39.

  The memory controller 31 controls the overall data transfer and is connected to the various I / Fs described above. The receiving unit 36a is connected to the memory controller 31 via the controller I / F 36. As described above, the reception unit 36 a receives transmission data from the controller 7 and outputs the transmission data to the CPU 30 via the controller I / F 36 and the memory controller 31. A monitor device 9 is connected to the video I / F 37. An external memory card 5 is connected to the external memory I / F 38 and can access a backup memory or the like provided in the external memory card 5.

  A speaker 9 a built in the monitor device 9 is connected to the audio I / F 39. The speaker 9a outputs sound data read from the ARAM 35 by the DSP 34 and sound data directly output from the disk drive 40. A disk drive 40 is connected to the disk I / F 41. The disk drive 40 reads data stored on the optical disk 4 arranged at a predetermined reading position, and outputs the data to the bus 42 and the audio I / F 39 of the game apparatus 10.

Next, the controller 7 will be described with reference to FIG.
The controller 7 has a housing 71 formed by plastic molding, for example. The housing 71 has a substantially rectangular parallelepiped shape whose longitudinal direction is the front-rear direction, and is a size that can be gripped with one hand of an adult or a child as a whole.

  A cross key 72 c is provided on the center front side of the upper surface of the housing 71. The cross key 72c is a cross-shaped four-direction push switch, and operation portions corresponding to four directions (front and rear, left and right) indicated by arrows are arranged on the cross-shaped projecting piece at intervals of 90 °. When the player presses the operation unit in any direction of the cross key 72c, an operation signal indicating the direction is transmitted from the controller 7 to the game apparatus 10.

  A large number of button switches are provided behind the cross key 72 c on the top surface of the housing 71, and when each button is turned on, a corresponding operation signal is transmitted from the controller 7 to the game apparatus 10. Among these button switches, the A button 72a is provided in the forefront (closer to the cross key 72c).

  On the other hand, a recess is formed on the lower surface of the housing 71. The recess on the lower surface of the housing 71 is formed at a position where the player's index finger or middle finger is positioned when the player holds the housing 71. A button switch 72b is provided on the rear inclined surface of the recess. The button switch 72b is an operation unit that functions as a B button.

  The button switch 72h provided on the front side of the cross key 72c on the upper surface of the housing 71 is a power switch for turning on / off the game apparatus 10 main body remotely.

  In addition, an imaging element 743 (see FIG. 4) for capturing an image in front of the controller 7 is provided on the front surface of the housing 71. The imaging element 743 constitutes a part of the imaging information calculation unit 74 (see FIG. 4). When the controller 7 is supported toward the monitor device 9, the image sensor 743 images the light emitting units 8 </ b> L and R provided on the upper surface of the monitor device 9. The imaging information calculation unit 74 detects the orientation of the controller 7 based on the imaging positions of the light emitting units 8L and R in the imaging element 743.

Next, the internal configuration of the controller 7 will be described with reference to the block diagram of FIG.
In FIG. 4, the controller 7 includes a communication unit 75, an acceleration sensor 701, and a vibrator 704 in addition to the operation unit 72 and the imaging information calculation unit 74 described above.

  The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744. The infrared filter 741 allows only infrared light to pass through from light incident from the front of the core unit 70. The lens 742 condenses the infrared light that has passed through the infrared filter 741 and outputs the condensed infrared light to the image sensor 743. The image sensor 743 is a solid-state image sensor such as a CMOS sensor, for example, and images the infrared rays collected by the lens 742. Therefore, the image sensor 743 captures only the infrared light that has passed through the infrared filter 741 and generates image data. Image data generated by the image sensor 743 is processed by an image processing circuit 744. Specifically, the image processing circuit 744 processes the image data obtained from the image sensor 743 to detect light from the high-luminance portion, that is, the light from the light emitting units 8L and R, and generates coordinate data indicating their position coordinates. Output to the communication unit 75.

  The acceleration sensor 701 is an acceleration sensor that detects acceleration on three axes of the controller 7 in the vertical direction, the horizontal direction, and the front-rear direction. Data indicating the acceleration detected by the acceleration sensor 701 is output to the communication unit 75.

  The communication unit 75 includes a microcomputer (microcomputer) 751, a memory 752, a wireless module 753, and an antenna 754. The microcomputer 751 controls the wireless module 753 that wirelessly transmits transmission data while using the memory 752 as a storage area during processing.

  An operation signal (key data) from the operation unit 72, an acceleration signal (acceleration data) from the acceleration sensor 701, and coordinate data from the imaging information calculation unit 74 are output to the microcomputer 751. The microcomputer 751 temporarily stores the input data (key data, acceleration data, coordinate data) in the memory 752 as transmission data to be transmitted to the receiving unit 36a.

  Here, the wireless transmission from the communication unit 75 to the receiving unit 36a is performed every predetermined cycle, but since the game processing is generally performed in units of 1/60, a shorter cycle than that is performed. It is necessary to send in. When the transmission timing to the receiving unit 36a comes, the microcomputer 751 outputs the transmission data stored in the memory 752 as a series of operation information and outputs it to the wireless module 753. The wireless module 753 radiates operation information from the antenna 754 as a radio wave signal using a carrier wave having a predetermined frequency.

  The vibrator 704 may be a vibration motor or a solenoid, for example. Since the vibration is generated in the core unit 70 by the operation of the vibrator 704, the vibration is transmitted to the hand of the player holding it, and a so-called vibration-compatible game can be realized.

≪Description of game program≫
Next, a game program executed on this game apparatus will be described. This game program is a so-called hunting action game, in which a player character operated by a player battles an enemy character (monster) that is a non-player character, and advances the game by subjugating the monster. When the player character encounters a monster in the field (hunting ground), the player character attacks the monster using weapons and items while avoiding the monster attack, and damages and defeats the monster.

  A physical strength value that is a parameter indicating the vitality is set for the monster. The physical strength value decreases according to the attack power value when the player character is attacked. When the physical strength value becomes 0, the monster dies. That is, the physical strength value decreases due to the attack of the player character who is the battle opponent.

  Furthermore, the monster is set with a stamina value that is a parameter indicating the activity ability. The stamina value is reduced (consumed) when the monster performs a predetermined stamina consumption action. That is, the stamina value is reduced by the monster's own action.

  The physical strength value is recovered by performing a predetermined physical strength recovery action such as meal or sleep. On the other hand, the stamina value increases (recovers) by performing a predetermined stamina recovery action. The stamina value also recovers over time. In the present embodiment, the stamina value MAX (maximum value) is 1000, and when the stamina value is equal to or less than a predetermined value (0), it is assumed that the stamina value recovers 500 after a predetermined time (2 minutes). The recovery conditions and numerical values are not limited to this.

  And the action form (state) of a monster is changed by this stamina value. That is, when the stamina value falls below a predetermined value (for example, when it becomes 0), the monster is made tired. This fatigued state is referred to as “fatigue state”, and the normal non-fatigue state is referred to as “non-fatigue state”. Thereby, the degree of fatigue of the monster can be expressed using the stamina value.

  The stamina consuming action is an action that consumes the monster's stamina and causes fatigue, and differs depending on the monster, but for example, intense or aggressive actions such as rush, air movement, breathing, etc. correspond to the stamina consuming action. On the other hand, normal behavior such as walking monsters and looking around does not correspond to stamina consumption behavior.

  In addition, a parameter called “power value” is set for the weapon equipped by the player character. Each time a monster receives an attack with a weapon (for example, a hammer hit) from the player character, the power value of the weapon is accumulated in the monster. This accumulated value (total value) is referred to as “accumulated value”. And the monster has a “power value endurance value” that indicates the strength of the resistance against the power value, and if the accumulated value exceeds the power value endurance value, the monster will blow away and faint and become unable to move I do. Stamina is also consumed when performing this jarring action.

  Conversely, the stamina recovery action is an action that restores the monster's stamina to rejuvenate. For example, when the monster eats, the stamina recovers to MAX (1000) with a probability of 100%. Further, if the monster succeeds in the eating restraint technique such as biting on the player character, if there is a stamina value of the monster at that time, the stamina is restored by a certain value (for example, 100) for each bite. On the other hand, when there is no stamina value (0), the stamina recovers to a certain value (for example, 500) when the monster catches (restrains) the player character. The numerical value is an example, and the present invention is not limited to this.

  The monster is provided with a state (status) indicating an attitude toward the player character. In the “normal state” and “warning state” where the player character is not fighting, the monster performs normal actions such as movement and meal. In a battle state in which the player character is fighting, the monster performs a battle action against the player character. Each state will be described later.

  The behavior of these monsters is basically determined by lottery based on the behavior lottery table except for some behaviors. The action lottery table is provided with a behavior lottery table in a non-fatigue state and a behavior lottery table in a fatigue state in each of the above states. By switching this table and performing lottery, the behavior of the monster is fatigued. Variations according to can be given.

  A game system as shown in FIG. 5 can be functionally realized by causing the above-described game device to read a game program for executing such a game. The game system includes an operation detection unit 50, a game progress control unit 51, a player character control unit 52, a non-player character control unit 53, a monster fatigue control unit 54, a game space control unit 55, a drawing processing unit 56, and the like. .

  The operation detection unit 50 includes a data processing unit such as the CPU 30 and the GPU 32 and the controller 7, detects various operations of the player, and transmits them to the game progress control unit 51. The game progress control unit 51 includes a data processing unit such as the CPU 30 and the GPU 32, generates a virtual game space and a character, changes the game space according to the player's operation, the passage of time, etc. The game is progressed by performing processing such as activity.

  The player character control unit 52 generates a player character in the game space and controls its activity based on operation information input from the operation detection unit 50. The non-player character control unit 53 generates a non-player character in the game space and controls its activity. The main non-player character is an enemy character monster that fights against the player character. The monster fatigue control unit 54 sets either a “non-fatigue state” or a “fatigue state” for the monster based on the stamina value, and controls the transition between both states.

  The game space control unit 55 generates a game space of the field (hunting ground) selected based on the operation information input from the operation detection unit 50, and controls the environment such as weather and day / night changes in the game space. . The drawing processing unit 56 includes a data processing unit such as the CPU 30 and the GPU 32, generates a game image in which the game space, characters, and the like generated by the game progress control unit 51 are projected on a two-dimensional screen, and outputs the game image to the monitor 9b.

  The monster is provided with the following “state” as an element for determining the action form. “Normal state”, “Warning state”, “Battle state”, “Non-fatigue state”, “Fatigue state”, “Anger state”. Among these, “normal state”, “warning state”, and “battle state” are states (statuses) indicating attitudes of the monster toward the player character, and one of these is alternatively selected as the state of the monster at that time. Is done. The “non-fatigue state” and “fatigue state” are states indicating the degree of fatigue of the monster itself, and one of these is alternatively selected as the state of the monster at that time. Further, the “anger state” set only in the battle state is a state indicating the anger level of the monster during the battle.

  As described above, each of the monsters is set to any one of “normal state”, “warning state”, “battle state”, “non-fatigue state”, and “fatigue state”. In the battle state, the “anger state” is set according to the battle situation.

  The non-player character control unit 53 sets one of three states of “normal state”, “warning state”, and “battle state” as the state of the monster according to the relationship between the monster and the play character.

  The “normal state” means a normal state in which the monster has not found the player character (for example, the player character is not within the sight range of the monster). Perform normal actions such as.

The “warning state” is a state in which the player character is found (for example, the player character is within the sight range of the monster), but there is no danger of entering the battle state, and the player character is wary. This risk can be expressed, for example, by a value calculated based on the possibility that the player character will attack the monster (for example, a parameter called an indicative price). Specifically, when the distance between the monster and the player character is short, a high value that increases the risk (indication price) is calculated, and it is dangerous even when the player character is performing an action that is likely to attack. A high value is calculated so as to increase the sex (indication price). When the calculated indicative price reaches a predetermined value, it shifts from the alert state to the battle state because the risk is high. The alert state is easier to shift to the battle state than the normal state, but the monster performs the same action as the normal state.

  The “battle state” is a state in which the monster finds the player character and is ready to fight with the player character. The player character is traced, and a fighting action such as breathing and biting is performed. In the alert state and the battle state, the player character is lost from the state of finding the player character (not within the field of view), and returns to the normal state when a certain time has passed.

  Further, the monster fatigue control unit 54 sets one of “non-fatigue state” and “fatigue state” for the monster based on the stamina value. Specifically, when the stamina value decreases to “0”, the monster is set to this fatigued state. This fatigue state ends after the stamina value of the monster is recovered after a predetermined time. For example, after the fatigue state continues for 2 minutes, the stamina value of a constant value (500) is recovered. Further, when the stamina value is “0” and the stamina value is recovered by the stamina recovery action as described above and the continuation for a predetermined time, the monster is caused to perform a predetermined stamina return action. For example, a motion indicating that the stamina has recovered, such as raising a thorn on the monster's wing while bravely bracing, is performed.

  The non-player character control unit 53 determines (selects) the action of the monster by switching the action lottery table according to these states and performing the lottery. Specifically, the action lottery is performed using the action lottery table for only the normal action not including the battle action in the normal / warning state, and the action lottery table including the battle action in the battle state. Thereby, the feature of the action for each state as described above can be expressed.

  Also, in the normal / warning state, a common action lottery table is used for the non-fatigue state and the fatigue state.When the basic posture is won, the behavior that takes the basic posture according to the state in the non-fatigue state or the fatigue state is taken. Do. On the other hand, in the battle state, action lottery tables dedicated to the non-fatigue state and the fatigue state are set, and a table adapted to each state is used. Note that both the behavior lottery table in the normal / warning state and the behavior lottery table in the battle state may be provided in two types: the behavior lottery table in the non-fatigue state and the behavior lottery table in the fatigue state.

  Hereinafter, details of each state will be described with reference to FIG. 6 showing display modes of “non-fatigue state” and “fatigue state”.

  First, the “non-fatigue state” in the normal / warning state is a normal state that has a monster stamina value and is not in a fatigue state. Then, normal actions such as walking and looking around are performed. As shown in FIG. 6A, there is no characteristic change in the display mode of the monster.

  On the other hand, the “fatigue state” in the normal / warning state is a state in which the stamina value of the monster is “0” and the user is tired. Although the behavior such as walking is not different from the non-fatigue state, the basic posture (fatigue posture) is taken in the behavior of taking the basic posture, unlike the non-fatigue state. Moreover, as shown in FIG.6 (C), compared with the non-fatigue state, a part of display mode of a monster differs. For example, the model is changed so that the thorns on the wings are laid, and a drooling effect is generated at the mouth.

  Next, the “non-fatigue state” in the battle state is a state that is not a fatigue state or an anger state. The monster performs a normal battle action (FIG. 7) such as “breath”, “with biting dash”, etc., against the player character. As shown in FIG. 6B, there is no characteristic change in the display mode of the monster.

  On the other hand, the “fatigue state” in the battle state is a state in which the stamina value of the monster is “0” and the player is tired. The monster performs a fighting action dedicated to a fatigue state (FIG. 8) such as “brace (brass faint)”, “biting with a dashes (moving after a dashes)”, and “tired basic posture”. Further, as in the fatigue state in the normal state and the alert state, as shown in FIG. 6 (C), a part of the display mode of the monster (slowing thorns and drooling) is different from the non-fatigue state.

  Here, the above-mentioned behavior of “breath” and “breath (brace faint)” is the same kind of behavior. Breath behavior in a non-fatigue state is an action in which a monster breathes out a fireball after inhaling and collecting. The fireball is a spherical three-dimensional object, and is discharged toward the player character. Fireballs explode when they collide with any object. When the player character hits the fireball, the player character receives damage (the physical strength value decreases).

  On the other hand, the breath (brass faint) behavior in the fatigue state is similar to the breath behavior in the non-fatigue state, but the monster inhales and collects, but then the fireball cannot be exhaled and the fireball explodes at the mouth It is an action that cannot be exhaled. This represents a state in which the fireball fails to be expelled due to fatigue. That is, the behavior of breath (brass fading) in a fatigue state indicates “defect behavior” relative to the behavior of breath in a non-fatigue state. Therefore, since the fireball does not fly in the fatigued state, it is not necessary to avoid the fireball, and the attack can be made by approaching the monster. However, if you are involved in an explosion at your mouth, you will be damaged. However, the damage at this time is smaller than the damage caused by hitting the fireball.

  Similarly, the behavior of “furious dash biting (can move after a dash)” in a fatigue state is also “defective behavior” with respect to the “figure dash biting” behavior in a non-fatigue state. The non-fatigue-stated strong dash biting action is an action in which a monster bites after a violent dash (rush) toward the player character.

  On the other hand, the action of biting a strong dash in a fatigue state (moving after a heavy dash) is an action that falls after the heavy dash (rush) and falls down to the front, and cannot be bitten. This expresses a state where he / she stumbled during a heavy dash due to fatigue. “Ski” can be made while the monster is stumbling and falling (it is defenseless), so avoiding a heavy dash and stumbling and falling is a great attacking opportunity for the player character.

  Further, in the battle state, the fatigued behavior has a “tired basic posture”, but this behavior also has a larger gap than the non-fatigue state “basic posture”. The basic posture in a non-fatigue state is an action that moves the neck and tail up and down on the spot without moving, and does not attack the player character. Therefore, it can be said that the player character is relatively easy to attack the monster during this action. However, since the monster moves its neck and tail up and down, there is a risk that it will fail to attack (splashing etc.), or hit the tail and take damage.

  On the other hand, the fatigued basic posture is an action that takes a posture in which the head is lowered with less movement compared to the basic posture in the non-fatigue state. Therefore, the skies are larger than the basic posture in a non-fatigue state, and the attack is likely to succeed. In particular, since the head which is the weakest point of the monster is lowered, it is a great chance for the player character to attack the head of the monster. For some monsters, the action time of the basic posture in the fatigued state is set longer than the action time of the basic posture in the non-fatigue state, so the skies are larger and easier to attack.

  Furthermore, the specific action in the fatigue state has a longer time for skiing (unprotected) in the action than in the non-fatigue state. Specifically, the playback time between frames that are susceptible to attack in a certain operation is slowed down to increase the gap. For example, in the behavior of breathing out, the playback time of the action of predicting breath (breathing in and collecting) is delayed. Such an action with a long skiing time is referred to as “skiing action”.

  Further, the duration of the effect of the predetermined item used by the player character against the monster is longer in the fatigue state than in the non-fatigue state. The predetermined item is an item for suppressing the behavior of the monster, and includes, for example, a pitfall, numbness, and a flash ball. A monster's action suppressed by the effect of an item is called "restraint action". By making the monster's “restrained behavior” longer to play during fatigue, you can express how the item's effect lasts for a long time.

  For example, if a monster gets stuck in a pitfall that the player character has set on the ground in the game space, he / she will not move for a certain period of time and will be in a skimmed state (behaves in a restrained state). Is longer than the non-fatigue state. In addition, the time for which the body cannot move due to numbness (performs a restraint action) is also made longer than in the non-fatigue state. A numbing trap is placed on the ground in the same way as a pitfall. When a monster hits a trap, it becomes numb and does not move, causing a skid. In addition, when the flash ball is used, the monster becomes inoperable (restrained behavior) for a certain period of time due to the generated intense flash and becomes a skid state, but this ski time is made longer than the non-fatigue state.

  The “anger state” in the battle state is a state where the anger value provided for the monster is equal to or greater than a predetermined value, and the monster is angry. The anger value is a parameter indicating the anger level of the monster, and is accumulated by receiving an attack from the player character. In this anger state, the monster performs a battle action (FIG. 9) dedicated to the anger state, which has higher speed, attack power, and the like than the non-fatigue state. Further, as shown in FIG. 6D, for example, an effect is generated such that a flame blows out at the mouth of the monster.

  As described above, by changing the behavior pattern and display mode of the monster according to the non-fatigue state and the fatigue state, it is possible to give the monster individuality and realize a more realistic game. For example, when a monster is fighting against a player character (in a battle state) and the stamina value becomes 0 (becomes exhausted), the action lottery table is changed from the non-fatigue state table (FIG. 7) to the fatigue state. By switching to the table for use (FIG. 8) and drawing a lot, it is possible to take a defective action in the middle of the battle or lengthen the time of the skiing, and make the monster weaker than usual.

  That is, when a monster gets tired due to his own fighting behavior or the like, it is possible to incorporate into the game an event that is assumed in an actual battle, in which the attack is likely to fail or the opponent is more likely to be attacked. In addition, the player can perform a strategic battle in which the monster is not forcedly attacked but is attacked after being fatigued.

  As described above, the behavior of the monster is determined by lottery based on the behavior lottery table. There are three action lottery tables used in the battle state: an action lottery table in a non-fatigue state (FIG. 7), an action lottery table in a fatigue state (FIG. 8), and an action lottery table in an anger state (FIG. 9). Consists of tables. Further, each table is composed of five tables for each distance. Which table is used depends on the state of the monster (non-fatigue, fatigue, anger) and the positional relationship between the player character and the monster (very close, short, medium, long, other) Distance).

  7 to 9 are diagrams showing action lottery tables in the battle state stored in the non-player character control unit 53. FIG. 7 shows an action lottery table in a non-fatigue state, FIG. 8 in a fatigue state, and FIG. 9 in an anger state. In each figure, five tables are shown for each positional relationship (distance) between the player character and the monster. Each table stores a monster's attack type (type of action) and its winning probability.

  In the action lottery table in the non-fatigue state of FIG. 7, the types of attack actions (attack types) that can be selected decrease as the distance increases from the ultra-short distance table to the other distance table. Is set to Furthermore, in the ultra-short distance table, the winning probabilities such as “tail attack” and “biting”, which are low in power, are set high. However, in tables other than the above, such as “high dash biting”, which is high in power, etc. The winning probability is set high.

  The behavior lottery table in the fatigue state of FIG. 8 includes the above-described defect behavior (the behavior described in parentheses in the table) as compared to the same type of attack of the table in the non-fatigue state of FIG. For example, “Very dash biting (moving after dashing)”, “Breath (brace fading)” or the like is set. Further, the probability of taking the “tired basic posture” is set higher than the probability of taking the “basic posture” in the non-fatigue state, and the probability of occurrence of skiing is high. Therefore, the period during which the player character is likely to attack is longer than in the non-fatigue state.

  In addition, among the actions in the action lottery table in the fatigue state of FIG. 8, those having the same names as the actions in the table in the non-fatigue state of FIG. This includes actions with long skies (slow playback time between frames) (behavior with skies). An example of an action with a long gap is the above-mentioned “brace”. On the other hand, “Summer Salt”, “Tail Attack”, etc., do not change the length of the ski, and perform the same kind of behavior as the non-fatigue state.

  In this embodiment, “defect behavior”, “skin-behaved behavior”, “tired basic posture (fatigue posture)”, and “restraint behavior” for a longer time than the non-fatigue state are “fatigue behavior”. However, the action is not particularly limited to these actions, and any action may be used as long as the player character is advantageous in battle when the monster is in a fatigued state. For example, an action may be performed in which parameters such as attack power and speed are set lower than in a non-fatigue state.

  In the action lottery table in the anger state of FIG. 9, the speed of the attack action is faster and the damage given to the player character is higher than the same type of attack in the table in the non-fatigue state of FIG. In addition, aggressive actions dedicated to the anger state such as “high output flame injection” are set.

  Then, one of these tables is selected according to the state of the monster. For example, if the monster is in a non-fatigue state and the positional relationship between the player character and the monster is very close, the action drawing table for ultra close distance shown in FIG. 7 is determined as the table to be used. When the table to be used is determined, a lottery based on the lottery probability in the table is performed to determine the behavior of the monster. Since each monster's action (motion) takes different time, this action lottery is performed every time each motion ends.

  In the present embodiment, the same action lottery table is used in the normal state and the alert state, but another action lottery table may be used for each state.

  FIG. 10 is a diagram showing a monster management table set in the non-player character control unit 53. In this table, various data relating to game progress for monsters are stored. Specifically, a storage area for a monster name, a monster ID, a physical strength MAX value, a physical strength value, a stamina MAX value, a stamina value, a power value, an anger value, and a state flag is set.

  The physical strength value is a parameter indicating the life force of the monster, and the current value and the MAX value are managed in this table. The stamina value is a parameter indicating the activity ability of the monster, and the current value and the MAX value are managed in this table as well as the physical strength value. The power value is a parameter indicating damage (separate from the physical strength value) received by the player character's specific attack, and the anger value is a parameter indicating the anger level of the monster.

  The state flag is a flag indicating the state of the monster. Any one of the normal state flag, the alert state flag, and the battle state flag is alternatively set according to the relationship between the monster and the player character. Either the non-fatigue state flag or the fatigue state flag is alternatively set according to the stamina value. Further, the anger state flag is set according to the anger value of the monster in the battle state.

  Hereinafter, the stamina value update processing and the like of this embodiment will be described with reference to the flowcharts of FIGS. 11 and 12.

  FIG. 11 is a flowchart of a main routine of monster control performed by the non-player character control unit 53. The process shown in FIG. 6 is repeatedly executed, for example, every frame (1/30 second or the like).

  First, the state (status) of the monster is checked, and it is determined whether the monster is in a normal, alert, or battle state (S10). Next, a monster action process for drawing a monster action is performed using an action lottery table corresponding to the state of the monster (S11). In addition, when the fatigue state flag is set in the previous (previous frame) stamina value update process (S12), a lottery is performed based on the behavior lottery table in the fatigue state. Further, in the battle state, a lottery is performed based on an action lottery table corresponding to the distance between the monster and the player character.

  Next, a stamina value update process is performed to update the stamina value based on the state and action of the monster (S12). This stamina value update process will be described later with reference to FIG. Next, effect generation processing for generating an effect corresponding to the action of the monster is performed (S13). Similarly, when the fatigue state flag is set, the model is changed so that the thorns on the wings are laid, or a drooling effect is generated at the mouth. Next, other game processes such as a monster life / death determination process are performed (S14). Finally, in order to generate a game image having the contents determined by the above processing, a drawing process for transmitting information to the drawing processing unit 56 is performed (S15).

  FIG. 12 is a flowchart for explaining the stamina value update process performed by the non-player character control unit 53. The stamina value update process is a process for updating the stamina value based on the state or action of the monster.

  First, it is determined whether or not the monster has performed a predetermined stamina consumption behavior (S20). When a stamina consumption action is performed (YES in S20), a stamina value consumption process is performed (S21). On the other hand, when the stamina consumption action is not performed (NO in S20), it is determined whether or not the monster has performed a predetermined stamina recovery action (S22). When the stamina recovery action is performed (YES in S22), stamina value recovery processing is performed (S23).

  Next, it is determined whether or not the stamina value is “0” (S24). If the stamina value is “0” (YES in S24), it is determined whether or not the monster is in an angry state (S25). If the monster is in an anger state (YES in S25), the anger state and the fatigue state do not coexist, and the stamina value update process is terminated. On the other hand, if it is not an anger state (NO in S25), it is determined whether or not a fatigue state flag is set (S26). If the fatigue state flag is not set (NO in S26), the fatigue state flag is set (S27), the timer is set (S28), and the stamina value update process is terminated.

  On the other hand, if the fatigue state flag is set (YES in S26), it is determined whether or not a predetermined time has elapsed (S29). If the predetermined time has not elapsed (NO in S29), the stamina value update process is terminated. When the predetermined time has elapsed (YES in S29), a stamina recovery process is performed (S30), the return action of the monster is set (S31), the fatigue state flag is reset (S32), and the stamina value update process is terminated.

  On the other hand, if the stamina value is not “0” (NO in S24), it is determined whether or not the monster is in a fatigued state (S33). If the monster is not fatigued (NO in S33), the stamina value update process is terminated. On the other hand, if it is a fatigue state (YES in S33), the return action of the monster is set (S34), the fatigue state flag is reset (S35), and the stamina value update process is terminated.

  Regardless of whether the monster is in the “normal state”, “warning state”, or “battle state”, the stamina value update process is performed based on the flowchart of FIG. Depending on whether or not the fatigue state flag is set in this process (S27, S32, S35), the type of the action lottery table selected in S11 of FIG. 11 changes. In particular, in the battle state, the type of action lottery table selected varies depending not only on whether the fatigue state flag is set, but also on the distance between the monster and the player character. In the normal state and the alert state, since the battle is not performed, the same table is selected regardless of the distance between the monster and the player character.

  The selection of the monster's action is not limited to the lottery based on the table storing the winning probability for each action. For example, the actions may be selected in a preset order, may be selected according to the positional relationship with the player character, or may be selected by random lottery with no win probability specified.

  In the present embodiment, the player character battles with a monster on the ground, but it may be a case where the player character battles on the hollow or a case where only the monster is on the hollow and battles with the player character on the ground.

Moreover, this stamina value update process is not limited to a stamina value, but can be applied to other parameters related to monsters. In addition, when the stamina value falls below the predetermined value, even if the monster is set to “savory state” or “slow state” instead of “fatigue state”, an action lottery table including actions related to it is performed. Good.

  In the present embodiment, a game device which is a stationary home game machine has been described as an example. However, the game control program may be incorporated into another general-purpose computer such as a portable game device or a personal computer. Is possible. It can also be implemented as an arcade game machine. The present invention is not limited to monsters, but can be applied to any non-player character having stamina. Furthermore, the present invention can be suitably applied regardless of the genre as long as it is a game in which a player character and a non-player character battle each other.
