Description

  The present invention relates to a program, an information storage medium, and a game system.

  In recent years, an image generation system that generates an image viewed from a virtual camera (a given viewpoint) for an object such as a character placed and set in a virtual three-dimensional space (hereinafter referred to as an “object space”) has been put into practical use. Has been. Such an image generation system has come to be used in various systems as being capable of experiencing virtual reality, and in particular, in game systems, it is regarded as important for improving reality. .

  Conventionally, such a game system is based on the input of an operation means for each character object, such as a game in which a plurality of characters fight on a role playing game (RPG), for example, or in a predetermined process. Based on this, the attack operation and the defense operation in the battle are executed.

  In particular, recently, as such a game system, in order to improve the presence and thrill in the battle, a game system that performs an action related to the battle of each character object in real time is known.

Specifically, this game system is provided with a time measuring means such as a timer for measuring a preset time for each character object, and when each preset time is measured, An action related to the battle of the character object is executed (for example, Patent Document 1).
Japanese Patent No. 2794230

  However, in the game system as described above, although the start timing of the action of each character object is specified for each character object in order to improve the presence and thrill in battle, the action of the character object The agility characteristic (quickness), which is one of the characteristics of important character objects in battle, cannot be used as a relative agility characteristic between the corresponding character objects, and the agility characteristic is accurately incorporated into the game. I can't. That is, in the game system as described above, the timing at which each character object can be actuated is determined only by its own agility characteristics, so there is a problem that a blank time occurs in which no character object is acting during the game. there were.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to quantify and incorporate differences in relative agility characteristics between characters regarding the behavior of character objects. Another object of the present invention is to provide a program, an information storage medium, and a game system that can eliminate the inconvenience of a blank time during which no character object can act during a game.

  (1) The present invention is a game system for a game in which a plurality of character objects including a player object that is a character object to be operated by a player act in an object space, and the character is applied to the plurality of character objects. A parameter setting unit that sets a first parameter associated with the agility characteristic for each object, and a character object that can be acted on based on the first parameter is determined as an actable object, and a given condition is satisfied. An actionable object determination unit that repeatedly performs the process of determining the actionable object until the parameter setting unit includes at least one of the actionable object and a character object other than the actionable object. The first parameter of one of the character objects is updated every time the actionable object is determined, and the actionable object determination unit performs the following based on the updated first parameter of each character object. This relates to a game system that determines an actionable object. The present invention also relates to a program that causes a computer to function as each of the above-described units and an information storage medium that stores such a program.

  According to the present invention, since the first parameter is updated based on the first parameter associated with the agility characteristic for each character object, the actionable object is repeatedly determined until a given condition is satisfied. For example, in the case of a character object having a high agility characteristic, the number of actions is increased, and in the case of a character object having a low agility characteristic, the number of actions is reduced. Relative differences in agility characteristics (quickness) can be quantified and incorporated into the game.

  Therefore, according to the present invention, it is possible to provide the player with the pleasure of building a strategy during the game while considering the agility characteristics of each character object. Furthermore, according to the present invention, since one character object is always in an actionable state during the game, there is no generation of a blank time during which neither character object can act, and the player can play without feeling stress. A game can be offered.

  (2) In the game system, program, and information storage medium of the present invention, the parameter setting unit sets the first parameter in association with the agility characteristics of the plurality of character objects, and the plurality of characters. The ratio of the first parameter of the other character object to the first parameter of the character object having the highest agility characteristic among the objects is obtained, and the ratio is compared with a given threshold value. If it is determined that the threshold value is exceeded, the first parameter of the other character object may be corrected by clipping the ratio to the threshold value.

  In this way, by adjusting the first parameter of the other character object based on the first parameter of the character object having the highest agility characteristic, for example, the ratio of the first parameter between the character objects Even if the difference is excessively large, it is possible to determine other character objects as actionable objects at a predetermined rate.

  Therefore, according to this aspect, the advantage / disadvantage in the game is unlikely to be unilateral due to the difference in agility characteristics between character objects, and even a character object with low agility can be moderately participated in a game event. It becomes like this.

  (3) In the game system, program, and information storage medium of the present invention, the parameter setting unit obtains the reciprocal of the second parameter given according to the agility characteristic of each of the plurality of character objects, The reciprocal of the second parameter may be set as the first parameter, and the actionable object determination unit may determine the character object having the smallest first parameter as the actionable object.

  In this way, since the first parameter can be normalized to a given value range, parameter management becomes easy and accurate calculation processing can be performed.

  (4) In the game system, program, and information storage medium of the present invention, each time the parameter setting unit determines the actionable object, at least a first parameter given to a character object other than the actionable object From the above, the first parameter may be updated by subtracting the first parameter given to the actionable object.

  In this way, when the first parameter is updated, the value of the first parameter is always decreased, so that the parameter fluctuates in a given value range. Therefore, according to this aspect, inconveniences such as parameter overflow can be eliminated and more accurate calculation processing can be performed as compared with the case of updating while incrementing the parameter.

  (5) In the game system, the program, and the information storage medium of the present invention, each time the parameter setting unit determines the actionable object, the first of character objects other than the actionable object and the actionable object. The actionable object may be updated by resetting the first parameter to a unique initial value.

  In this way, the first parameter of the character object determined as the actionable object is determined as the actionable object while the first parameter of the character object not determined as the actionable object is updated. Since the initial value unique to the character object (a value determined in advance for each character object) is reset, the magnitude relationship between the values of the first parameters after the update varies, and the first parameter is sequentially changed. To determine the actionable object.

  Therefore, according to this aspect, the relative difference of the agility characteristic in each character object is quantified and incorporated into the game, and the actionable object is always associated with the relative difference of the agility characteristic until a given condition is satisfied. Can be determined, and at the time of updating the first parameter, the processing load in the arithmetic processing can be reduced, and accurate arithmetic processing can be performed.

  (6) In the game system, program, and information storage medium of the present invention, the parameter setting unit temporarily changes the first parameter of a given character object according to an event that occurs during the game. You may do it.

  In this way, for example, when applied to a role playing game (RPG), the agility characteristics of the character object during the battle, such as damage based on an attack from the enemy object or a change in equipment during the battle of the character object, etc. This change can be reflected in the battle, so that the enjoyment of the RPG battle can be further improved.

That is, in this embodiment, the operation keys and the corresponding actions are fixed in principle, but the type of action assigned to the operation keys can be changed under specific conditions according to the progress of the game. It has become.

  The parameter setting unit 113 performs processing for setting (calculating) parameters necessary for various processes performed by the game processing unit 110.

  Specifically, when a battle is performed between a plurality of character objects, an actionable object determination parameter (first parameter) associated with the agility characteristic of each character object is set for the plurality of character objects. For example, the reciprocal of the quickness parameter (second parameter) given according to the agility characteristic of each of the plurality of character objects is obtained, and the reciprocal of the obtained quickness parameter is set as the actionable object determination parameter. be able to. The quickness parameter may be set as the actionable object determination parameter.

Are compared. When it is determined that the obtained ratio exceeds the threshold value, the actionable object determination parameter of the other character object is corrected by clipping the obtained ratio to the threshold value.

  The parameter setting unit 113 performs a process of updating the actionable object determination parameter of at least one of the character objects other than the actionable object and the actionable object every time the actionable object is determined.

  Specifically, the actionable object is updated by resetting the actionable object determination parameter to a unique initial value set at the start of the battle. For character objects other than the actionable object, the actionable object determination parameter is updated by subtracting the actionable object determination parameter given to the actionable object from the actionable object determination parameter given to the character object. . For the actionable object, its own value may be subtracted from the actionable object determination parameter.

  Further, the parameter setting unit 113 performs a process of temporarily changing the actionable object determination parameter of a given character object according to an event that occurs during the battle.

  The timer 115 (first timer, second timer) measures various times during the progress of the role playing game under the control of the timer control unit 116. In the present embodiment, the timer 115 measures various times used for the battle including the action time of the actionable object (that is, the actionable time limit).

  In particular, the timer 115 of the present embodiment is a timer (first timer) that measures the actionable time indicating the actionable time of the character object determined as the actionable object including the player object during the battle with the enemy object. Function as.

  In addition, when the player object is determined as an actionable object, the timer 115 is a time until the player object starts to behave, that is, for the player to think about the action of the player object. It functions as a timer (second timer) that measures a time limit (hereinafter also referred to as “sinking time”).

  Further, the timer 115 counts a count value (a variable of the count value), for example, at a frame (1/60 second, 1/30 second) update timing (a timing at which the vertical synchronization signal VSYNC output to the display unit becomes active). Time is measured by up. Note that the timer of this embodiment may measure time using a timer of a real-time clock included in the game system.

Specifically, the timer control unit 116 instructs the input processing unit 112 to start receiving or end receiving an input when the timer value indicates a predetermined time while the timer 115 is measuring the actionable time. When the predetermined time is indicated during the sinking time measurement, the timer 115 is caused to start measuring the actionable time. Under specific conditions, the actionable time is started without causing the timer 115 to measure the sinking time.

  In addition, the timer control unit 116 interrupts the time measurement of the actionable time only while the action of the character object is stopped under a specific condition, or the action time of the actionable object for a specific operation input. For example, the timer value is changed so as to be substantially extended.

  The movement / motion processing unit 117 (object action control unit) performs movement / motion calculation (movement / motion simulation) of an object, for example, a character object, a car, or an airplane. That is, the movement / motion processing unit 117 is configured to execute an object (particularly an enemy object and a player) based on operation data input by the player through the operation unit 160, a program (movement / motion algorithm), various data (motion data), and the like. A process for moving the object's character object) in the object space, a process for moving the object (motion, animation), and particularly a process for controlling various actions (movement / motion) during the battle.

  Specifically, a simulation process for sequentially obtaining object movement information (position, rotation angle, speed, or acceleration) and operation information (position or rotation angle of each part object) for each frame is performed. This frame is a unit for performing object movement / motion processing (simulation processing) and image generation processing.

  The virtual camera control unit 118 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, a process for controlling the position (X, Y, Z) or the rotation angle (rotation angle about the X, Y, Z axes) of the virtual camera (process for controlling the viewpoint position and the line-of-sight direction) is performed.

  The image generation unit 120 performs drawing processing based on the results of various processes (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ) Is input, and vertex processing is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary. In vertex processing, geometry processing such as vertex movement processing, coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, perspective transformation, or light source processing is performed, and an object is configured based on the processing result. Change (update, adjust) the vertex data given for the vertex group. Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (fragment processing) for drawing pixels constituting an image (fragments constituting a display screen) is performed. In pixel processing, various processes such as texture reading (texture mapping), color data setting / changing, translucent composition, anti-aliasing, etc. are performed to determine the final drawing color of the pixels that make up the image, and perspective transformation is performed. The drawing color of the object is output (drawn) to the drawing buffer 174 (buffer that can store image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) set in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  It should be noted that the vertex processing and pixel processing performed by the image generation unit 120 are performed by hardware that enables a polygon (primitive) drawing process to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). It may be realized. Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of rendering processing is high, and the expressive power can be greatly improved compared to fixed rendering processing by hardware. .

  The image generation unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the object data storage unit 175. Is done.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit 177 of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 177 of the storage unit 170 using the texture coordinates set (given) at the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing by a Z buffer method (depth comparison method, Z test) using a Z buffer 179 (depth buffer) in which a Z value (depth information) of a drawing pixel is stored may be performed. it can. That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer 179 is referred to. Then, the Z value of the referenced Z buffer 179 is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is the front side when viewed from the virtual camera (for example, a small Z value). If it is, the drawing process of the drawing pixel is performed and the Z value of the Z buffer 179 is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value). For example, in normal α blending, a process for obtaining a color obtained by combining two colors by performing linear interpolation with the α value as the strength of synthesis is performed.

  The α value is information that can be stored in association with each pixel (texel, dot), and is, for example, plus alpha information other than color information indicating the luminance of each RGB color component. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the game system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play.

  In addition, when a plurality of players play, game images and game sounds provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line), etc. It may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

2. In the following, in the game system of the present embodiment, a method for repeatedly determining an actionable object during a battle from the start of the battle until the battle is ended, and a case where the player object is determined to be an actionable object. A player object action control method will be described.

  In the role playing game, in the role playing game, the game system according to the present embodiment updates the quickness parameter of each character object until the battle ends after the battle is started. In accordance with the respective quickness parameters, the right of action is repeatedly given to any character object, that is, the character object is repeatedly determined as an actionable object.

  In the game system of this embodiment, each time an actionable object is determined, a player's operation input or a predetermined algorithm is set with a predetermined actionable time that advances in real time along the real time axis as a time limit. Various actions according to the above are executed for the determined actionable object (hereinafter, this battle method is also referred to as “time-shared real-time battle”).

  In particular, the game system according to the present embodiment assumes that the player object can be executed in response to an operation input when the player object is determined to be an actionable object, and the player object according to the player's operation input by a free idea. Can be made to act.

  Details of the actionable object determination method and the player object action control method in the game system of this embodiment will be described below.

2.1 Actionable Object Determination Method (1) Outline First, an outline of an actionable object determination technique in the game system of the present embodiment will be described.

  In the present embodiment, the enemy object and the player object that can be battled at any point in time between the start of the battle and the period from the start of the action of the actionable object determined last time to the end of the actionable time. A quickness parameter (second parameter) indicating the unique agility characteristic of the character object from among the teammate objects (the friend object may be a player object or a non-player character object (NPC)) The character object is determined (set) as an actionable object in accordance with the actionable object determination parameter (first parameter) obtained from (1).

  In this embodiment, in order to determine the next actionable object, after determining the actionable object, the actionable object and each character object other than the actionable object (hereinafter referred to as “behavior disallowed object”) The actionable object determination parameter of each character object is updated separately.

  In the present embodiment, the actionable object is repeatedly determined according to the updated actionable object determination parameter of each character object from the start of the battle to the end of the battle.

  In particular, in this embodiment, when an enemy object is determined as an actionable object, various actions such as an attack on the player object are executed according to a predetermined program (algorithm).

  In this embodiment, when a player object is determined as an actionable object, action processing of the player object as an actionable object described later is performed in accordance with the operation of the player.

  As described above, in the actionable object determination method according to the present embodiment, the quickness characteristic which is one of the important characteristics of the character object at the time of battle is quantified, and the actionable object is determined based on this. Yes.

  Therefore, according to the method of the present embodiment, for example, in the case of a character object having a quickness parameter indicating that the agility characteristic is high, the number of attacks increases and the agility characteristic is low. In the case of a character object having the quickness parameter shown, the number of attacks is reduced.

  Therefore, according to the method of the present embodiment, by using the agility characteristic of each character object, it is possible to enhance the sense of reality at the time of battle, and to repel enemy objects with a high agility characteristic at an early timing. Since it is possible to provide the player with the pleasure of building a strategy, the enjoyment at the time of battle in the role-playing game can be further improved.

  Further, according to the method of the present embodiment, one character object is always in an actionable state during a battle, so that no blank time during which no character object can act is generated, and the player does not feel stress. It is possible to provide a game that can be played.

  In the present embodiment, the end of the battle is, for example, when the battle such as the annihilation of the enemy object (win) or the annihilation of the player object including the ally object (defeat) is not established, and the player object escapes before the enemy Satisfying a predetermined termination condition (given conditions) such as when (escape).

(2) Specific Determination Method for Actionable Object Hereinafter, a method for determining an actionable object in the game system of the present embodiment will be described in more detail with reference to FIG.

  FIG. 2 is a diagram for explaining a method for determining an actionable object in the game system of the present embodiment. The details of the quickness parameter specific to each character object (the value serving as the basis of the initial value of the actionable object determination parameter) used when the actionable object is first determined, that is, used at the start of the battle will be described later. .

  In the game system of the present embodiment, the initial value of the actionable object determination parameter (reciprocal of the quickness parameter), which is a value unique to each character object set in advance when the battle is started, is compared, or the previous time Before the end of the actionable time of the actionable object, the actionable object determination parameter of each character object updated by the update process described later is compared, and the action indicating the minimum value among the actionable object determination parameters A character object having a possible object determination parameter is determined as an actionable object.

  Further, in this embodiment, when comparing the actionable object determination parameters, the reciprocal number of the quickness parameter, which is a value unique to each character object, is used as an initial value. By using the reciprocal number, The numerical value is normalized to a range of “0” to “1”, and update processing described later is executed by subtraction of parameters.

  In other words, the method of the present embodiment performs an arithmetic process accurately while preventing overflow or underflow of a value at the time of performing an update process, which will be described later, or by using a value having a small absolute value. In order to reduce the processing burden, the reciprocal of the quickness parameter indicating the agility characteristic of the character object is used as the actionable object determination parameter.

  In short, in the method of the present embodiment, when a battle is started, the reciprocal of the quickness parameter specific to each character object is calculated as an actionable object determination parameter, and the character having the smallest value among the calculated reciprocals is calculated. The object is determined as an actionable object that is allowed to act in the object space.

  In the method of the present embodiment, the character object having the smallest actionable object determination parameter next to the character object that has become the actionable object is expected to be determined as the next actionable object (hereinafter referred to as the actionable object). , Called “Behavior Scheduled Object”). By adopting such a method, for example, if display control is performed to notify the player of the scheduled action object, the player can determine the character object to be acted next time, so that a battle strategy can be established. It becomes easy.

  Further, in the method of the present embodiment, when a given actionable object is acting (after the actionable object determination parameter is updated after the last actionable object is determined, the actionable time in the actionable object is updated). Until it is finished), the actionable object determination parameter of each updated character object is compared, and the character object having the minimum value is determined as the actionable object that is allowed to act in the object space next. is doing.

For example, as shown in FIG. 2A, the enemy object EO is “3” and the teammate object AO including the player object PO is “3”, and the quickness parameter of each character object is When P = “20”, A1 = “15”, A2 = “12”, and E1 = E2 = E3 = “10”, according to the method of this embodiment, the actionable object determination parameters are respectively set. R is calculated as in the following formulas 1A to 1D. However, “P”, “A1”, “A2”, and “E” indicate arbitrary values, and R (PO) and the like are actionable objects in the parenthesis character object (in this case, the player object PO). Indicates the decision parameters.
R (PO) = (1 / P) = (1/20) = 0.050 (1A)
R (AO1) = (1 / A1) = (1/15) = 0.067 (1B)
R (AO2) = (1 / A2) = (1/12) = 0.083 (1C)
R (EO) = (1 / E) = (1/10) = 0.100 (1D)

  At this time, the calculated actionable object determination parameters are compared, and as shown in FIG. 2B, the player object PO having the minimum value is determined as the actionable object. For the determined actionable object, an image having a display D1 indicating that it is an actionable object is generated.

  In the method of the present embodiment, as shown in FIG. 2B, the teammate object AO1 is determined to be the action scheduled object that is predicted to be determined as the next actionable object, and is determined to be the action scheduled object. An image having a display D2 (hereinafter referred to as “next display”) D2 is generated.

  However, in the present embodiment, there is a case where the character object displayed next is attacked by the actionable object and is repelled, making it impossible to fight, and the action scheduled object is not necessarily determined as the actionable object. Is not limited. In other words, in the present embodiment, the update process described below is always performed before the object determination process for determining the next actionable object. Therefore, when the update process is performed, the battle is not possible. When the actionable object determination parameter does not become the minimum value, it is not determined as the next actionable object.

  In the method of the present embodiment, as shown in FIG. 2B, character objects (including action scheduled objects) that have not been determined as actionable objects, that is, ally objects AO1, AO2, and enemy objects EO1 to EO1. EO3 is set as an action disallowed object.

(3) Parameter Update Method Next, update of the actionable object determination parameter in the image generation system of the present embodiment will be described using FIG. FIG. 3 is a diagram for explaining a method for updating the actionable object determination parameter in the game system of the present embodiment.

  In the method of the present embodiment, when the actionable object is determined, until the next actionable object is determined, the actionable object determination parameter of each character object that is an action disallowed object that has not been determined as an actionable object, The actionable object determination parameter of the action disallowance object is updated by subtracting the actionable object determination parameter of the actionable object.

  Further, in the method of the present embodiment, when updating the actionable object determination parameter of the actionable object, the initial value unique to the character object (the quickness unique to each character object set in advance when the battle is started). (Reciprocal of the parameter) is reset (reset).

  That is, according to the method of the present embodiment, when updating the actionable object determination parameter, by reducing the value of each parameter, the calculation process is performed while preventing the value overflow or the like until the battle ends. It can be done accurately.

  For example, in the case where the value of the reciprocal R (PO) used when the actionable object is determined to be the actionable object by the player object PO is “1 / X”, FIG. 3 (A) and FIG. 3 (B). As shown, the actionable object determination parameter R (AO1) = “1 / S”, R (AO2) = “1 /”, which is the reciprocal of each quickness parameter of the ally object AO and the enemy object EO that are action-unpermitted objects. The update value N is calculated by subtracting the actionable object determination parameter R (PO) = “1 / X”, which is the reciprocal of the quickness parameter of the player object, from “T” and R (EO) = “1 / U”. It is like that.

  In this case, in the method of the present embodiment, the actionable object determination parameter of the player object PO is reset to the initial value R (Pi) = “1 / Pi” (Pi is a quickness parameter unique to PO). Thus, R (Pi) is calculated as the update value N.

That is, in the parameter updating method of this embodiment, the update value N of the actionable object determination parameter of each character object of the action disallowed object is calculated by the following expressions 2A to 2C, and the actionable object (player) is calculated by the following expression 3. The actionable object determination parameter of the object PO) is reset to the initial value R (Pi). However, “X”, “S”, “T”, “U”, and “Pi” indicate arbitrary values, and N (AO1) and the like are character objects in parentheses (in this case, ally object AO1). The updated value at.
N (AO1) = (1 / S) − (1 / X) (2A)
N (AO2) = (1 / T) − (1 / X) (2B)
N (EO) = (1 / U) − (1 / X) (2C)
N (PO) = R (Pi) = (1 / Pi) (3)

  Note that the image generation system of the present embodiment performs the next object action determination process based on each update value N calculated by the above expressions 2A to 2C and the above expression 3, and which of the next actionable objects is When the character object is determined, the next update process is performed until the action of the character object as the action object is completed.

For example, when the teammate object AO1 is determined as the actionable object based on the update value N of the above formulas 2A to 2C and the above formula 3, the update value (hereinafter simply referred to as “next update value”) N1. Is calculated based on the following equations 4A to 4C and the following equation 5, and the next update process is executed.
N1 (PO) = (1 / Pi)-{(1 / S)-(1 / X)} (4A)
N1 (AO2) = (1 / T) − (1 / X) − {(1 / S) − (1 / X)} (4B)
= (1 / T)-(1 / S)
N1 (EO) = (1 / U) − (1 / X) − {(1 / S) − (1 / X)} (4C)
= (1 / U)-(1 / S)
N1 (AO1) = (1 / A1i) (5)

  However, as described above, “X”, “S”, “T”, “U”, and “Pi” indicate arbitrary values, and N1 (PO) and the like are character objects in parentheses (in this case, , Player object PO), that is, the next update value of the actionable object determination parameter. 1 / A1i indicates an initial value of the actionable object determination parameter of AO1.

(2) Initialization of Actionable Object Determination Parameter Next, initialization of the actionable object determination parameter at the start of battle in the present embodiment will be described with reference to FIG. FIG. 4 is a diagram for explaining the initialization of the actionable object determination parameter at the start of the battle in the present embodiment.

  In the method of this embodiment, first, the reciprocal of the quickness parameter specific to each character object set at the start of the battle is set as the initial value of the actionable object determination parameter, and the initial value is compared.

  As a result of comparing the initial values of the actionable object determination parameters, the ratio between the actionable object determination parameter of the character object having the maximum agility characteristic and the actionable object determination parameter of the other character object (hereinafter referred to as “parameter ratio”). )) Exceeds a preset threshold value, the parameter ratio is clipped to the threshold value to correct the initial value of the actionable object determination parameter of the character object. Is going. In other words, in the method of the present embodiment, initialization is performed so that the parameter ratio between the character objects is equal to or less than the threshold value.

  Specifically, in the present embodiment, “2.3” is set as the threshold value, and all character objects are character objects having the highest agility characteristics (hereinafter “maximum agility characteristic objects”). The action in the object space is permitted once as an actionable object while the action is performed 2.3 times.

  For example, as shown in FIG. 4A, when a battle is performed between three enemy objects EO and three player-side character objects (player object PO and ally object AO), the behavior of each character object is determined. The initial values of the possible object determination parameters are R (PO) = 1 / P = “1/23”, R (AO1) = 1 / A1 = “1/15”, and R (AO2) = 1 / A2 =, respectively. “1/12”, R (EO1) = 1 / E1 = “1/5”, R (EO2) = 1 / E2 = “1/5”, R (EO3) = 1 / E3 = “1/5” In this case, the character object having the highest agility characteristic becomes the player object PO.

  Therefore, in the example shown in FIG. 4A, the parameter ratio with the initial value of the actionable object determination parameter of the other character object is calculated based on the initial value of the actionable object determination parameter of the player object PO. For the enemy objects EO1 to EO3 whose parameter ratio exceeds the threshold value “2.3”, the parameter R is obtained by correcting the initial value of the actionable object determination parameter so that the parameter ratio becomes “2.3”. (EO1) ′, R (EO2) ′, and R (EO3) ′ are obtained. Then, as shown in FIG. 4B, the initial values of the actionable object determination parameters of the enemy objects EO (EO1 to EO3) are each initialized to “1/10”.

  In the present embodiment, the quickness parameter varies depending on the character object, in particular, the equipment of the ally object including the player object. For example, when comparing the initial value of the actionable object determination parameter, the numerical value set for the equipment to be equipped for the battle to be carried out in the speed parameter unique to each character (equipment set to minus) In some cases, the quickness parameter of each character object may be changed.

  In this embodiment, the initial value of the actionable object determination parameter of each character object that is set at the start of the battle is used until the end of the battle. However, if the equipment is changed during the battle, The initial value of the actionable object determination parameter is changed when the quickness parameter of each character object is changed according to the battle situation, such as when an attack on another character object is received during the battle. You may make it fluctuate in.

2.2 Action Control Method (1) for Player Character Becomes Actionable Object First, an outline of the action control method for the player character in the image generation system of this embodiment will be described.

  In the method of the present embodiment, during the battle, the actionable time is measured during the permitted period of the actionable object in the object space, and the player's operation input is performed within a predetermined time limit. Various actions (at least one of movement and movement) corresponding to the player object can be executed.

  For example, movement on an object space, attack action against an enemy object, defense action against an attack from an enemy object, action on a character object of a friend such as recovery or revival of a damage of an ally object or cooperation on an attack on an enemy object, object space It is possible to cause the player object to execute an action for avoiding a battle with the enemy object due to movement within the player object.

  For this reason, according to the method of the present embodiment, not only the selection of enemy objects to fight against and the determination of the type of attack, but also the determination of the position of the player object in the object space during battle, etc. It is possible to determine freely according to the player's action, and the degree of freedom of action of the player object can be improved.

  Therefore, according to the method of this embodiment, when a plurality of characters battle with each other, it is possible to expand the action of the player object and accurately reflect the player's strategy in the battle.

  In this embodiment, the player object clears a predetermined event in a predetermined role-playing game, such as repelling a predetermined enemy object or acquiring a predetermined item, or during a role-playing game of a player object. The concept of a party class is introduced in which the difficulty level of the player character's operation input varies in accordance with the progress of the game, such as when an experience value obtained by quantifying experience exceeds a predetermined value.

  For this reason, in the game system of the present embodiment, based on the party class, the action of the player object at the time of battle, such as the type of attack that can be executed, the action against the ally object, or the method for measuring the actionable time is specified. As the game progresses, players are required to be quick in strategy formulation and ingenuity in strategy, and from the initial stage of the game It is possible to maintain the enjoyment of the battle until later.

(2) Specific Method for Player Object Behavior Control Next, a specific method for player object behavior control in the image generation system of the present embodiment will be described in detail with reference to FIGS. FIG. 5 is a diagram for explaining the behavior of the player object when the player object attacks the enemy object. FIG. 6 shows the player when the player object performs a recovery behavior on the ally object. It is a figure for demonstrating the action in an object. FIG. 7 is a diagram for explaining the behavior of the player object when the player object avoids the battle, and FIG. 8 is a diagram for explaining the behavior of the player object when the time limit has elapsed. It is.

  First, in the present embodiment, when a player object is determined to be an actionable object, a time limit due to a sinking time, which will be described later, has passed when the first operation input after the start of acceptance of the player's operation input is performed. Or a condition for starting the action of the player object (hereinafter, also simply referred to as “start condition”), such as when the player becomes operable (when acceptance of the player's operation input described later is started). )), The time allowed for action is measured.

  In this embodiment, the player's operation input is accepted only within a predetermined time limit, and the action control of the player object is performed based on the player's operation input. . In other words, the player's operation input is accepted from when the start condition is satisfied until the timer indicates a predetermined time (hereinafter referred to as “time limit”).

  In the present embodiment, the behavior control of the player object can be freely performed on the assumption that it can be executed in response to an operation input.

  Specifically, based on the player's operation input, the movement in the object space, the attack action on the enemy object, the defense action against the attack from the enemy object, the recovery or revival of the damage of the ally object, or the attack on the enemy object Actions such as cooperation with respect to a friendly character object, actions related to avoiding a battle with an enemy object, and the like are controlled.

[Movement in object space]
In the present embodiment, the player object can freely move in the object space in accordance with the player's operation input within the actionable time, and the player object is designated and moved. Designation of direction, movement distance, motion when moving such as jumping, and the like are controlled based on operation input of the player.

  In the method of the present embodiment, by freely moving the player object in the object space, an attack on an enemy object, a recovery action on a friend character object, which will be described later, a battle against the enemy object, or a temporary Diversify attacks, such as evacuation, and specify various actions as well as attack actions.

  In the method of this embodiment, when the party class is higher, the movement speed in the object space is faster than when the party class is lower (for example, in the case of a higher party class). The player object's action ability is changed in accordance with the player's operation input proficiency and the enemy object's ability to improve as the game progresses (1.5 times the moving speed in the lower party class).

[Attack on enemy objects]
Further, in this embodiment, when an attack operation is instructed by a player's operation input, an enemy object (hereinafter referred to as “the target object” as much as possible) based on the orientation of the player object in the object space and the distance to the enemy object. "Target object") is set. In this embodiment, an attack instructed by an operation input is performed on the determined target object.

  For example, as shown in FIG. 5A, the player object PO is moved to a position where an attack directed to the enemy object EO1 reaches a distance (hereinafter referred to as “attack distance”) by an operation input from the player. Then, when an instruction of “attack by sword” is issued, according to the method of this embodiment, as shown in FIG. 5B, the enemy object EO1 is set as the target object, and the enemy object is set in the player object PO. The attack action (action to slash with a sword) instructed by the operation input to the EO1 is executed.

  Further, in the present embodiment, the attack action that can be instructed by an operation input by the player is, for example, a limb of the player object or equipment (equipment such as a bomb) equipped on the player object such as striking or shooting with a gun. It can be classified into two types: normal attacks (hereinafter referred to as “normal attacks”) that can be executed in a product (including goods) and special attacks such as special moves (hereinafter referred to as “special attacks”).

  In this embodiment, the distance / range where the attack reaches the enemy object is determined in advance depending on the type of attack action, and the enemy object exists within the distance / range where the attack reaches. Will succeed in the attack by the player object. If the attack is successful, damage is given to the enemy object by changing the health parameter, or processing such as repelling the enemy object or ending the battle is performed. To do. On the other hand, if there is no enemy object within the range / range of attack, the attack fails.

  Further, in this embodiment, there is an attack that affects not only the enemy object set as the target object but also the entire enemy object depending on the technique such as magic. In this case, in the method of this embodiment, the target object is The technique is executed on all enemy objects that can execute the technique without being determined, that is, on all enemy objects that can fight.

  Furthermore, in the method of the present embodiment, the enemy object to be attacked is not determined by the player's operation input, but is determined based on the orientation of the player object in the object space and the distance to the enemy object. You may enable it to select the enemy object of attack object by the operation input of a player.

[Recovery action to ally object]
Also, in this embodiment, when an instruction for a recovery action for a teammate character object is input by a player's operation input, based on the orientation of the player object in the object space and the distance to the teammate object, The ally object to be determined is determined and the instructed recovery action is performed.

  Specifically, the player's operation input restores the ally object's damage, revives the retreated ally object, recovers the ally object from an abnormal state, and takes action to improve the ally object's ability. It controls the recovery behavior for objects.

  For example, as shown in FIG. 6A, when the teammate object AO1 is attacked and the enemy object EO is not capable of fighting, the player object PO is directed toward the teammate object AO1 by the player's operation input. Then, the player object PO is moved to a position where the skill for recovering the status abnormality of the ally object AO1 reaches the position where the technique reaches (hereinafter referred to as “skill arrival distance”), and the instruction of the technique for recovering the status abnormality Then, as shown in FIG. 6B, the player object PO executes the technique (in this case, the technique to be revived) instructed by the player's operation input to the ally object AO1.

  In this embodiment, depending on a technique such as magic, there is a technique that affects not only the teammate object set as the target but also the entire teammate object. In this case, all the target teammate objects are not selected, In the case of a technique for recovering the status object, that is, the technique for recovering the status abnormality, the technique for recovering the status abnormality can be executed on all the friend objects.

  Further, in the present embodiment, not only with the ally object, but also with respect to the player object, the player object such as recovery or recovery of damage, recovery from an abnormal state, action for improving his / her ability, etc. The recovery action for the object can be executed.

[Avoiding battles with enemy objects]
In the present embodiment, an action for avoiding a battle with an enemy object can be performed by a predetermined operation input from the player.

  Specifically, when a player object is determined as an actionable object and acceptance of its operation input is started, if a predetermined operation input for avoiding a battle is made, avoiding a battle with an enemy object Therefore, behavior control for moving from the place where the battle is performed in the object space to a different place is performed.

  In this embodiment, the player object is an actionable object and can be instructed by an operation input at any timing as long as it is within the actionable time, but in this embodiment, the player object is as described above. When the status is abnormal, it is not possible to control the behavior of avoiding or escaping a battle with an enemy object.

  For example, in this embodiment, as shown in FIG. 7A, when the player object PO is determined to be an actionable object during a battle and a predetermined operation input for avoiding the battle is input, the battle is performed. Escape from the space in which the battle is taking place (battle field: second object space) and move from the space in which the battle takes place to a different space (map field: first object space) as shown in FIG. 7B. It is like that.

  As described above, according to the method of the present embodiment, a variety of player object actions such as an attack on an enemy object, a recovery action against a friendly object, etc. and an action related to avoiding a battle with the enemy object are provided, and only the attack action is performed. In addition, various actions such as being able to move freely in the space can be instructed.

  Therefore, according to the method of this embodiment, when a plurality of characters battle with each other, not only actions for performing battles such as selection of enemy objects to fight against and determination of attack types, but also actions and objects other than battles. It is also possible to expand the free-change of the standing position of the player, and to accurately reflect the strategy of the player in the battle.

  In this embodiment, in the action for the ally object, various actions can be performed together with the ally object according to the operation input such as not only the recovery action but also cooperation in the attack on the enemy object. .

  On the other hand, in this embodiment, when the action time exceeds the time limit, control is performed such that the operation input is rejected and no further action of the player object can be instructed. Therefore, when moving in the object space, the behavior of the object is controlled such that the movement of the player object stops on the spot after the time limit has passed.

  That is, in the present embodiment, as shown in FIG. 8A, the player object PO is directed to the enemy object EO1, and the movement is limited to the position where the attack reaches the enemy object EO1. When the time elapses, the player object PO is stopped at the position when the time limit has elapsed. In other words, in the present embodiment, as shown in FIG. 8A, when the time limit is reached at the point V (the end time of the time limit), the player object PO can be moved to the expected arrival position. First, at point V, the action is controlled to stop.

  However, if the above-described control is uniformly performed with respect to the behavior of the object, there may be inconveniences such as the object being stationary in an unnatural state during the operation. For this reason, in the method of the present embodiment, even when the time limit is exceeded, an operation input is received by the time limit and control of a series of operations such as an attack action and a jump is started. Controls to continue the action of the player object until the operation ends.

  For example, as shown in FIG. 8B, when jumping and attacking the enemy object EO, even if the time limit is reached at the point V before landing, the player object is landed until the attack ends. The action of the PO is controlled, and the player object PO is stopped at the landing point W.

  In this way, by controlling so that the operation that the operation input is accepted by the time limit can be completed, the operation input related to the special technique that requires a long time to display the effect and the motion according to the action of the player object, A strategy can be made to allow the player object to perform actions that display effects and motions in a short period of time without performing until the time limit for accepting input is reached. Become.

  On the other hand, in the present embodiment, when a predetermined party class (for example, the highest party class in the role playing game) is set, for each action of the player object corresponding to the player's operation input, Control is performed to change the correspondence between the operation input and the action of the player object. That is, under specific conditions, control is performed such that the assignment of an object action command to an operation input by a player changes each time the object acts.

  That is, in the present embodiment, in the normal case, the operation key for inputting the operation and the action of the player object specified by the operation key are fixedly associated with each other, but in the case of a predetermined party class Each time the player object is determined as an actionable object and an operation for inputting the action is performed, the correspondence relationship between the action of the player object specified by the operation key and the operation key is changed, and the player's action is changed. Operation input is accepted.

  In this way, by changing the correspondence between the operation input of the player and the action of the player object for each action of the player object, according to the method of the present embodiment, an operation for causing the player object to execute the action It becomes difficult to input, and it becomes possible to give a strong interest to the player regarding the operation input at the time of battle.

(3) Measurement Control Method for Actionable Time Next, a measurement control method for actionable time in the present embodiment will be described with reference to FIGS. 9 and 10. FIG. 9 is a diagram for explaining the relationship between the actionable time measured by the method of the present embodiment and the party class, and FIG. 10 is an image of the actionable time displayed during the action of the player object. It is an example.

  The image generation system according to the present embodiment receives a player operation input from a given timing to a time limit when a player object is determined to be an actionable object, and controls the player object to act according to the received operation input. In order to do this, the actionable time of the player object is measured.

  In particular, in the present embodiment, the action start condition is changed based on the progress status of a role-playing game such as a party class, that is, the measurement of the actionable time is started according to the progress status of the game. The timing is changed.

  Therefore, according to the method of the present embodiment, the fun of the battle is maintained from the early stage to the later stage of the game by requiring quickness at the time of strategy planning and the ingenuity of the strategy as the game progresses. It can be made to.

  Specifically, “when the player's first operation input is performed in a state where the player object is determined to be an actionable object and the player has not yet made an operation input related to the player object's action”, “described later "When the time limit due to the sinking time is over" or "when the player object is determined to be an actionable object and the player's operation input regarding the action of the player object is possible without passing the sinking time etc. (player described later) The actionable time is measured from when the start condition indicating the start of the action of the player object is satisfied, such as “when the reception of the operation input is started”).

  In this embodiment, since the start condition is satisfied, a time limit determined in advance according to the progress of the game such as a party class (for example, in the early stage of a role-playing game, after 5 seconds from the start of measurement, In the latter period, the time measurement for executing the action of the player object is performed in accordance with the player's operation input until 4 seconds after the start of measurement).

  For example, as shown in FIG. 9, in the initial stage of the role playing game scenario such as when the party class is lower, the actionable time measurement is not started when the action of the player object in the object space is stopped. It has become. That is, it is the same as that the sinking time described later is unlimited.

  Further, in the initial stage of the role playing game scenario, even when the measurement of the actionable time is once started, the action in the object space of the player object is stopped during the actionable time. When the possible time measurement is interrupted and the player's operation input is resumed, the measurement of the possible action time is canceled and the remeasurement is started from the interrupted time. That is, the actionable time is measured only when the player object is acting in the object space. In this way, at the initial stage where the operation input is not yet matured, the player can use it as a time for considering the next action strategy while the action of the player object is stopped.

  On the other hand, as shown in FIG. 9, in the middle stage of the role playing game scenario such as when the party class is a middle class, a sinking time described later is set as a finite period, and an operation for defining the action of the player object The measurement of the actionable time is automatically started after measuring a predetermined time (for example, 1 second or 3 seconds) from the state where the input is enabled, and the actionable time is measured until a predetermined time limit. It is like that.

  In the middle stage of the role playing game scenario, even when the action of the player object is stopped, the time measurement of the actionable time is continued without interruption. By doing so, the player must quickly determine the action of the player object and perform an operation input, thereby amplifying the thrill of battle.

  In the middle stage of the role-playing game scenario, if an operation input that defines the behavior of the player object is input during the sinking time, the sinking time measurement is forcibly terminated (the sinking time measurement is canceled). ) And start measuring the possible action time.

  On the other hand, as shown in FIG. 9, in the later stage of the role playing game scenario in which the party class is the higher class, the sinking time described later is also omitted, and the player object is determined as the actionable object and the action is defined. Measurement of actionable time is started from the state in which the operation input is enabled (the state in which the player's operation input is started), and the actionable time is measured until a predetermined time limit It is supposed to be.

  As described above, according to the method of the present embodiment, a player who is unfamiliar with the operation input for defining the behavior of the player object such as a beginner causes the player object to act until a predetermined time unless the operation input is performed. Therefore, the player object can be considered carefully without being measured.

  Then, according to the method of the present embodiment, for a player who is skilled in operation input, the time measurement of the actionable time is started immediately after the operation input is performed, so that the action of the player object can be executed. Therefore, it is possible to omit the time until the operation input is started and to improve the operation interface environment.

  Therefore, according to the method of the present embodiment, even from beginners to players who have mastered the operation, even if the mastery of the operation and the understanding of the game are different, it is possible to entertain each player with a battle. Such an operation interface environment can be provided.

  In the present embodiment, for example, as shown in FIG. 10, during the battle, the actionable time is displayed by the numerical display T1, and the image for displaying the numerical display T2 and the bar display T3 of the remaining time is displayed. Is generated so that the player can accurately and easily visually recognize the remaining time during which the current actionable object can act.

  Further, in the present embodiment, not only the party class, but also a change in experience level determined by the experience value acquired by the player during the game, input of a predetermined player on the game program, acquisition of equipment, When a predetermined event occurs including a player object acting on its own, such as repelling an enemy object or elapse of a predetermined time from the start of the game, the start timing of the actionable time is changed as described above. May be.

  In addition to the above, in the present embodiment, the time limit for the allowed action time to be measured and the currently measured timer value are changed according to the type of attack of the player object.

  Specifically, in order to give the benefit of the normal attack when performing the normal attack, the time limit for the actionable time is extended every time the normal attack is performed.

  That is, according to this method, when a normal attack action is executed by a player object, the time during which an operation can be input is substantially increased, unlike when an attack action is executed by a special move. As described above, the player can be given the benefit of changing the time limit.

  As a result, according to the method of the present embodiment, by adding value with respect to the normal attack action, the attack method is balanced so that only the operation input related to the attack of the special move is not performed, and the strategy of the player is achieved. Diversity can be provided, and as a result, it is possible to give a strong motivation to perform an operation input related to a normal attack in battle.

  Instead of changing the time limit as described above, the measured timer value is changed every time a normal attack is performed, that is, the measured timer value is set to a predetermined value every time a normal attack is performed. By shortening by the number of seconds (for example, 0.2 seconds), the time for performing the operation input may be substantially increased.

(4) Sinking Time Measurement Control Method In the present embodiment, the sinking time is a period until the start of measurement of the actionable time when the player object is determined to be an actionable object according to the progress of the game. Is to measure.

  In particular, in the present embodiment, the presence / absence of the sinking time and the length of the sinking time differ depending on the party class, and the presence / absence of the sinking time and the length thereof are determined based on the party class (substantially the progress of the game). The sinking time measurement control is performed while judging the above.

  Specifically, when the player object is determined to be an actionable object in the middle stage of a role playing game scenario, such as when the party class is a middle class, an operation input that defines the action of the player object is possible Control is performed so as to measure a predetermined time (for example, 1 second or 3 seconds) as the sinking time from this state.

  In the present embodiment, the measurement of the actionable time is started after the measurement of the sinking time, and if the operation input is started by the player even when the sinking time is being measured, the timer is used for the sinking. The time measurement is forcibly terminated and the measurement of the actionable time is started.

  Similar to the actionable time, regarding the sinking time, an image that displays the state being measured during the battle may be generated. For example, instead of the image showing the measurement state of the actionable time in the areas T1 to T3 displaying the actionable time in FIG. 10, an image displaying the sinking time and the remaining time may be generated.

2.3 Other battle processing (defense processing)
Further, in the present embodiment, when the actionable object is an enemy object and an attack is received from the enemy object, the defense can be executed according to the operation input of the player.

  Specifically, when a player performs a predetermined operation input while receiving an attack from an enemy object, it is possible to execute an action that defends against the attack of the enemy object even if the player object is not an actionable object. It is like that.

  Also, depending on the party class, if the enemy object is attacked and the player object is defended based on the player's operation input, the enemy object's attack ends when the player further performs a predetermined operation input. Later, a predetermined counter attack (counterattack) can be executed for a certain period of time.

  For example, when an enemy object is being attacked, if the player can cause the player object to execute a defense operation more accurately by an operation input, depending on the party class, an operation input for performing a counterattack may be prompted. The operation input for the counterattack is controlled so as to be received at a predetermined timing. In this case, when the player performs an operation input at a predetermined timing, the player object can execute a predetermined counterattack action for a certain period (for example, 2 seconds) after the enemy object has finished attacking.

  As described above, according to the method of the present embodiment, even when attacked by an enemy object, a counterattack opportunity can be obtained while defending the attack based on an operation input at an appropriate timing. Therefore, not only can the damage caused by the attack be avoided, but the enemy object can also be damaged.

  Therefore, according to the method of the present embodiment, even when an enemy object attacks, an opportunity for a player's operation input is provided, so that tension can be maintained even when the player object is not in principle capable of acting. Can be done.

  During a counterattack, the player object receives an input of a special attack such as a movement in the object space, a normal attack or a special move, and executes a movement / motion in the object space in accordance with the received player operation input. Behavior is controlled. However, in this embodiment, a special attack can be accepted only for a predetermined party class, for example, only when the party class is higher.

3. Processing of this embodiment Next, a detailed processing example of this embodiment will be described with reference to FIGS. 11 and 12.

  FIG. 11 is a flowchart showing details of the object determination process when determining an actionable object in this embodiment. FIG. 12 shows the action of the player object when the player object is determined as the actionable object. It is a flowchart which shows the detail of a process.

  First, detailed processing when determining an actionable object in the present embodiment will be described with reference to FIG.

  First, when the player object confronts the enemy object (encounter) and the battle is started (Yes in step S1), the quickness parameters of the ally object and the enemy object that can fight the player object are read out, and the reciprocal thereof is obtained. An initial value of the actionable object determination parameter is obtained (step S2).

  Then, the actionable object determination parameter is initialized. First, the initial value of the actionable object determination parameter obtained for each character object is compared (step S3). Next, as a result of comparing the actionable object determination parameters of each character object, the parameter ratio between the actionable object determination parameter of the character object having the highest agility characteristic and the actionable object determination parameter of other character objects exceeds the threshold value. It is judged whether it is (step S4). At this time, when there is an actionable object determination parameter whose parameter ratio exceeds the threshold (Yes in step S4), the value is corrected so that the parameter ratio is clipped to the threshold (step S5). If not (No in step S4), the process proceeds to step S6. When there is an actionable object determination parameter whose parameter ratio exceeds the threshold value, the value of the actionable object determination parameter is corrected so that the parameter ratio becomes the threshold value “2.3”. .

  Next, among the actionable object determination parameters of each initialized character object, the character object having the actionable object determination parameter indicating the minimum value is determined as the actionable object, and the action indicating the second smallest value is possible A character object having an object determination parameter is determined as an action scheduled object (step S6).

  Subsequently, the process which updates the actionable object determination parameter used for step S6 is performed (step S7). Specifically, the actionable object determination parameter of the character object determined as the actionable object is subtracted from the actionable object determination parameter of each character object that is an action disallowed object that has not been determined as the actionable object. Further, the actionable object determination parameter of the actionable object is reset (reset) to the initial value obtained in step S2.

  Finally, it is determined whether or not the action of the actionable object has ended (step S8). If it is determined that the action of the actionable object has ended (Yes in step S8), whether or not the battle with the enemy object has ended. Is determined (step S9). Specifically, it is determined whether or not the ally object including the enemy object or the player object has been completely destroyed and whether or not the avoidance of the battle has been executed.

  At this time, if it is determined that the battle with the enemy object has not ended (No in Step S9), the process proceeds to Step S6, and if it is determined that the battle with the enemy object has ended (Step S9) Yes in S9), the control process related to the battle is terminated.

  Next, details of the action process of the player object when the player object is determined as the actionable object will be described with reference to FIG.

  First, when a player object (hereinafter, also simply referred to as “PO”) is determined as an actionable object (Yes in step S11), the time of the sinking time is measured based on the progress of the game such as the current party class. The presence or absence is determined (step S12).

  At this time, if it is determined not to measure the time of the sinking time (No in step S12), the process proceeds to step S13, and if it is determined to measure the time of the sinking time (step S12). Yes), the process proceeds to step S20.

  Next, in the process of step S12, if it is determined not to measure the sinking time, it is determined whether or not to measure the actionable time based on the player's operation input based on the progress of the game. Judgment is made (step S13).

  At this time, when it is determined that the actionable time is measured based on the player's operation input (Yes in step S13), the process proceeds to step S14, and the actionable time is determined based on the player's operation input. If it is determined not to perform measurement (No in step S13), the process proceeds to step S22.

  Next, in the process of step S13, when it is determined that the actionable time is measured based on the operation input of the player, the time limit for the actionable time is set based on the progress of the game, Acceptance of operation input is started (step S14).

  Next, when an operation input from the player is detected (step S15), the actionable time is measured (step S16). Note that the behavior of the player object is controlled based on the detected operation input from the detection of the operation input of the player until the time limit.

  Next, it is determined whether or not the time limit has elapsed in the actionable time being timed (step S17). If it is determined that the time limit has not yet elapsed (No in step S17), step S18 is performed. If it is determined that the time limit has passed (Yes in step S17), the process proceeds to step S24.

  Next, in the processing of step S17, when it is determined that the time limit has not yet elapsed in the actionable time being timed, it is determined whether or not the action of the player object has stopped (step S18). ).

  At this time, if it is determined that the action of the player object is not stopped (No in Step S18), the process proceeds to Step S17, and if it is determined that the action of the player object is stopped (Step S18). (Yes in S18), the measurement of the actionable time is interrupted (step S19), and the process proceeds to step S15.

  On the other hand, if it is determined in the process of step S12 that the time measurement of the sinking time is performed, the measurement end time is set in the sinking time, and the time measurement is started (step S20).

  Next, it is determined whether or not a predetermined detection is made as to whether or not the end time is detected in the time measuring time, or whether or not the player's operation input is detected (step S21), and elapse of the end time of the sinking time If it is determined that an operation input is detected by the player during the sinking time (Yes in step S21), the process proceeds to step S22.

  On the other hand, when it is determined in the process of step S13 that the actionable time is not measured based on the operation input of the player, or the elapse of the sinking time end time is detected in the process of step S22. If it is determined, or if it is determined that an operation input has been detected by the player during the measurement of the sinking time, a time limit is set for the actionable time based on the progress of the game and the operation input is accepted. The actionable time is measured (step S22).

  When the measurement of the actionable time is started, the action control of the player object is performed based on the player's operation input until the time limit is reached.

  Next, it is determined whether or not the time limit has elapsed in the actionable time being timed (step S23). If it is determined that the time limit has elapsed (Yes in step S23), the process of step S24 is performed. Then, the acceptance of the player's operation input is terminated (step S24).

  It should be noted that the behavior of the player object is freely controlled according to the operation input from the start of the reception of the player operation input in step S14 and step S22 until the player operation input in step S24 is completed.
