A reception unit receives the operation by the player. A determination unit determines, for each of the targets, whether the type of operation received and the type of operation allocated to the target overlapping on the target line match up or not with timing that the target overlaps on the target line. When the determination unit determines the mismatching of the types, a changing unit changes the mode in which the targets to which the same operation as the operation type allocated to the target overlapping on the alignment line are allocated are displayed on a screen by the display unit.

Description

  The present invention relates to a game apparatus, a game control method, and a program that are suitable for making it easier for a player to determine the types of targets that are sequentially presented.

  A game in which a player moves his / her body and plays is widespread in amusement halls and the like. For example, Patent Document 1 discloses a dance game device that guides the timing of stepping and the like, and allows a player to experience a dance sensation by stepping on a step in time with music. In recent years, there are dance game devices that require not only steps but also movements using the entire arm and body, and more complex and highly interesting games are known.

Japanese Patent No. 3003851

  In a dance game as described above, the direction of stepping and the direction of moving an arm are generally indicated by objects sequentially presented in a game image. However, the greater the number of objects presented to the player, the more difficult it is for the player to discern those objects. In particular, there is a demand for game beginners to present each object in an easily distinguishable manner.

  The present invention solves the above-described problems, and an object of the present invention is to provide a game device, a game control method, and a program suitable for making it easy for a player to determine the types of targets that are sequentially presented. And

  A game device according to a first aspect of the present invention includes a display unit, a reception unit, a determination unit, and a change unit, and is configured as follows. In the following description, a dance game in which a player takes a step and moves an arm according to a direction indicated by an object moving in the screen will be described as an example.

  The display unit is a display unit that displays an aim and a plurality of targets on the screen, and each of the plurality of targets is assigned a type of operation to be performed by the player, and the player performs the type of operation assigned. Is displayed so that the target and the target overlap at the timing to be performed.

  Here, in the dance game, the target is an object that moves in the screen. The aim is a predetermined position in the screen. It is assumed that the player is required to perform an operation such as stepping or moving an arm in the direction indicated by the object when the center of the object overlaps the predetermined position. That is, the display unit displays at a timing at which the player should perform an operation such that any of the plurality of objects or the centers of the plurality of objects overlap at a predetermined position.

  The accepting unit accepts an operation by the player.

  For example, when the player takes a step or moves his / her arm, the reception unit receives information regarding the timing and direction of the movement of the player.

  The determination unit determines, for each target, whether or not the accepted operation type matches the operation type assigned to the target that overlaps the aim at the timing when the target overlaps the aim.

  For example, when the center of an object for which a step is to be taken in the right direction (hereinafter referred to as “right direction object”) overlaps a predetermined position, the type of operation performed by the player and the operation assigned to the object. It is determined whether or not the types match. When the player steps in the right direction when the center of the right direction object overlaps the predetermined position, the determination unit determines that the accepted operation type matches the operation type assigned to the target. judge. On the other hand, if the player performs an action other than stepping in the right direction when the center of the right direction object overlaps a predetermined position, or if no operation is performed, the determination unit is accepted. It is determined that the operation type does not match the operation type assigned to the target.

  When it is determined that the changing unit does not match, the change unit is assigned the same operation type as the operation type assigned to the target that overlaps the aim among the targets displayed on the screen by the display unit. Change the form in which the target is displayed.

  For example, if the player steps to the left when the center of the right object overlaps a predetermined position, the type of operation accepted by the determination unit does not match the type of operation assigned to the target. It is determined that In this case, the changing unit changes the form of the right direction object displayed on the screen after the determination.

  According to the present invention, even if a plurality of types of targets are displayed on the screen, a target that is misoperated by the player is displayed in a different form from other targets. it can.

  Further, the changing unit may increase the degree of change of the form as the difference between the timing at which the operation is received by the receiving unit and the timing at which the operation is to be performed is large.

  For example, when an operation on the right direction object is required, the larger the difference between the timing at which the player steps to the right and the timing at which the center of the right direction object overlaps a predetermined position, the larger the form of the right direction object. Change.

  According to the present invention, since the target form is changed based on the deviation of the operation timing by the player, the degree of the operation timing deviation can be easily recognized.

  Alternatively, the change unit increases the degree of change in the form as the difference between the type of the accepted operation and the type of operation assigned to the target that overlaps the aim at the timing when the target overlaps the aim. You may make it do.

  For example, the difference in the type of object is obtained from the difference in angle in the direction indicated by the object. For example, at the timing when the right direction object overlaps a predetermined position, the change unit greatly changes the shape of the right direction object as the angle formed between the direction of the step that the player steps on and the right direction increases. That is, at the timing when the right object overlaps a predetermined position, the player makes an angle of 180 degrees with the right direction, rather than stepping up or down at an angle of 90 degrees with the right direction. When the step is taken in the left direction, the shape of the right direction object is greatly changed by the changing unit.

  According to the present invention, since the form of the target is changed based on the difference between the type of operation to be obtained and the type of operation by the player, the degree of operation error can be easily recognized by the change in the form. it can.

  In addition, when there are a plurality of types of targets whose form is to be changed, the change unit increases the degree of change in the form as the number of targets of the type increases.

  For example, the player does not step in the right direction at the timing when the right object overlaps a predetermined position, and after that timing, the number of right objects displayed on the screen by the end of the dance game is 40. Suppose there is. Further, for example, at a timing when an object for which the player requests to step in the left direction (hereinafter referred to as “left object”) overlaps with a predetermined position, the player does not step in the left direction. Assume that the number of leftward objects displayed on the screen by the end of the dance game is twenty. In this case, the changing unit changes the form of the right direction object and the left direction object, but sets the degree of changing the form of the right direction object larger than the degree of changing the form of the left direction object, and changes the form. Change.

  According to the present invention, it is possible to prevent an increase in the number of operation errors by increasing the degree of change of the form and making it easier to recognize as the target is displayed more frequently on the screen after an operation error. be able to.

  In addition, the change unit, after changing the form, if the determination unit determines that the type of the accepted operation matches the type of operation assigned to the target that overlaps the aim, You may make it return to a form.

  For example, it is assumed that the player does not step rightward at the timing when the center of the rightward object overlaps a predetermined position, and the form of the rightward object is changed. Next, when the player steps to the right at the timing when the center of the right object overlaps a predetermined position, the determination unit assigns the type of operation assigned to the right object and the type of operation by the player. Therefore, the changing unit returns the form of the right direction object to the original form.

  According to the present invention, when the player correctly recognizes the target, the target form can be restored.

Moreover, you may make it a form be the color attached | subjected to a target.
For example, when the player does not step in the right direction at the timing when the center of the right direction object overlaps a predetermined position, the changing unit displays the color attached to the right direction object displayed on the screen on the screen. Set to a different color from the objects that show other directions.
According to the present invention, since the color of the target is changed based on the success or failure of the operation of the player, even if a plurality of targets are displayed, it is possible to easily recognize a target whose operation is wrong due to the change of the color. it can.

Moreover, you may make it a form be the magnitude | size of a target.
For example, when the player does not step in the right direction at the timing when the center of the right direction object overlaps a predetermined position, the changing unit displays the size of the right direction object displayed on the screen. Larger than objects that show other directions.
According to the present invention, since the size of the target is changed based on the success or failure of the operation of the player, even if a plurality of targets are displayed, the target whose operation is erroneously recognized can be easily recognized by the change in size. be able to.

  A game control method according to a second aspect of the present invention is a game control method executed by a game device including a display unit, a reception unit, a determination unit, and a change unit, and includes a display step and a reception step. And a determination process and a change process, and is configured as follows.

  The display unit is a display unit that displays an aim and a plurality of targets on the screen, and each of the plurality of targets is assigned an operation type to be performed by the player. In the display step, the display unit displays the player Is displayed so that the aim and the target overlap at the timing at which the assigned type of operation should be performed.

  In the reception process, the reception unit receives an operation by the player.

  In the determination step, for each target, the determination unit determines whether or not the accepted operation type matches the operation type assigned to the target overlapping the aim at the timing when the target overlaps the aim. Determine.

  In the changing process, if the changing unit is determined not to match by the determining unit, among the targets displayed on the screen by the display unit, the same type of operation as the type of operation assigned to the target that overlaps the aim is Change the form in which the assigned target is displayed.

  A program according to another aspect of the present invention is configured to cause a computer to function as the game device and to cause the computer to execute the game control method.

  The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to provide a game device, a game control method, and a program that are suitable for making it easier for the player to determine the types of targets that are sequentially presented.

(Outline configuration of information processing device)
First, a typical information processing apparatus in which the game apparatus of these embodiments is realized will be described. In the following, in order to facilitate understanding, an embodiment in which the present invention is realized using an information processing device for games will be described, but the embodiment described below is for explanation, It is not intended to limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

  FIG. 1 is a schematic diagram showing a schematic configuration of a typical information processing apparatus 100 that performs the functions of the game apparatus according to the embodiment of the present invention by executing a program. Hereinafter, a description will be given with reference to FIG.

  The information processing apparatus 100 includes a central processing unit (CPU) 101, a read only memory (ROM) 102, a random access memory (RAM) 103, an interface 104, a controller unit 105, an external memory 106, and an image processing unit. 107, a DVD-ROM (Digital Versatile Disc ROM) drive 108, a NIC (Network Interface Card) 109, an audio processing unit 110, and a mat type controller 111.

  The CPU 101 controls the overall operation of the information processing apparatus 100, is connected to each component, and exchanges control signals and data. Further, the CPU 101 uses arithmetic operations such as addition / subtraction / multiplication / division, logical sum, logical product, etc. using an ALU (Arithmetic Logic Unit) (not shown) for a storage area called a register (not shown) that can be accessed at high speed. , Logic operations such as logical negation, bit operations such as bit sum, bit product, bit inversion, bit shift, and bit rotation can be performed. In addition, the CPU 101 itself is configured so that saturation operations such as addition / subtraction / multiplication / division for multimedia processing, vector operations such as trigonometric functions, etc. can be performed at a high speed, and those provided with a coprocessor. There is.

  The ROM 102 stores an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program stored in the DVD-ROM is read to the RAM 103 and the CPU 101 starts execution. The The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and chat communication. Further, the CPU 101 provides a variable area in the RAM 103 and performs an operation by directly operating the ALU on the value stored in the variable, or temporarily stores the value stored in the RAM 103 in the register. Processing is performed on the register, and the result of the operation is written back to the memory.

  The controller unit 105 is connected via the interface 104. The controller unit 105 receives an operation input performed when the player executes the game. Hereinafter, the controller unit 105 will be described with reference to FIG. FIG. 2 is an external view for explaining an outline of the controller unit 105.

  The controller unit 105 includes a controller 105a and a sensor bar 1051 as shown in FIG. The information processing apparatus 100 is connected to the sensor bar 1051 and the display 1053 via a predetermined cable.

For example, the controller 105a has an appearance similar to a remote control such as a television, and is connected to the information processing apparatus 100 wirelessly (by wireless communication). The player plays the game by holding the controller 105a with one hand. In the information processing apparatus 100, holding the controller 105a with the right hand is defined as a correct (standard) holding method.
The sensor bar 1051 is formed in a bar shape having a predetermined length, and is appropriately fixed on the upper portion of the display 1053 along the direction of the screen. In the sensor bar 1051, one light emitting element 1052 is embedded at each end. Note that the number of light-emitting elements 1052 to be embedded is an example and may be larger than these numbers.
The sensor bar 1051 receives power supply from the information processing apparatus 100 and causes the light emitting element 1052 to emit light appropriately.

When the CCD camera 105a1 is disposed at the tip of the controller 105a and the tip is directed toward the display 1053, the CCD camera 105a1 captures an image including the two light emitting elements 1052 (two light emitting points) of the sensor bar 1051. In addition, the controller 105a includes a wireless communication unit therein, and sequentially transmits information of captured images to the information processing apparatus 100 through wireless communication.
Then, the information processing apparatus 100 appropriately acquires the position and orientation of the controller 105a based on the positional relationship between the two light emitting points in the image sent from the controller 105a. For example, the CPU 101, the image processing unit 107, and the like analyze the positional relationship between two light emitting points visible from the controller 105a, and calculate the spatial position of the controller 105a and the direction of the tip (the direction of the longitudinal axis). Finally, it is obtained where the player is operating the controller 105a on the screen.
Such measurement of the position and direction of the controller 105a is performed, for example, every vertical synchronization interrupt (1/60 seconds).

Further, the controller 105a includes a triaxial acceleration sensor therein, and can measure the movement of the controller 105a in the triaxial direction. Note that the movement of the controller 105a may be measured by an angular velocity sensor, an inclination sensor, or the like instead of such an acceleration sensor.
The controller 105a sequentially transmits such measurement results (for example, acceleration information for each of the three axes) to the information processing apparatus 100.
The information processing apparatus 100 detects the movement of the controller 105a based on the measurement result sent from the controller 105a. For example, when the player performs an operation such as swinging, twisting, or striking the controller 105a, the movement direction is acquired. For example, if the player swings the controller 105a, the information processing apparatus 100 detects whether the controller 105a is swung in any of the directions 301 to 308.
Note that such movement of the controller 105a is also detected, for example, every vertical synchronization interrupt.

  A cross-shaped key 105a2 is arranged on the upper surface of the controller 105a, and the player can input an instruction specifying an arbitrary direction. An A button 105a3 and various buttons 105a5 are also arranged on the upper surface, and the player can input instructions associated with these buttons.

  On the other hand, the B button 105a4 is disposed on the lower surface of the controller 105a. The B button 105a4 has a depression formed on the surface to be pressed, and can be operated so that the player pulls the trigger.

  A plurality of small holes 105a6 are provided on the upper surface of the controller 105a so that clear sound can be output from a speaker embedded therein.

The indicator 105a7 on the upper surface of the controller 105a is appropriately lit so that the player can identify even when a plurality of controllers 105a are used.
The power button 105a8 prepared on the upper surface of the controller 105a instructs, for example, on / off of the information processing apparatus 100.

  Furthermore, a vibration mechanism such as a vibrator is disposed inside the controller 105a, and can generate vibration in response to instruction information sent from the information processing apparatus 100.

  As described above, the operation, position, and the like of the controller 105a can be obtained by the combination of the controller 105a and the sensor bar 1051. The measurement of the position of the controller 105a or the like is not limited to the method in which the CCD camera 105a1 captures the light emission point (the light emitting element 1052) of the sensor bar 1051, and other methods can be appropriately applied. For example, the position of the controller 105a or the like may be obtained from the time difference of wireless communication between two points via the sensor bar 1051, or the controller 105a or the like based on the principle of triangulation using ultrasonic waves or infrared rays. May be determined.

  The external memory 106 is detachably connected via the interface 104. The external memory 106 stores rewritable data indicating game play status (past results, etc.), game progress data, chat communication log (record) data in the case of a network match, and the like. The The player can store these data in the external memory 106 as appropriate by inputting instructions via the controller unit 105.

  The image processing unit 107 processes the data read from the DVD-ROM by an image arithmetic processor (not shown) included in the CPU 101 or the image processing unit 107, and then processes the processed data on a frame memory ( (Not shown). The image information stored in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor connected to the image processing unit 107. Thereby, various image displays are possible.

  The DVD-ROM mounted on the DVD-ROM drive 108 stores a program for realizing the game and image data and sound data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 108 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  Further, the image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.

  In addition, when the virtual space is configured in three dimensions, polygon information that is arranged in the three-dimensional space and to which various texture information is added is rendered by the Z buffer method, and a predetermined viewpoint position is used. It is also possible to perform a high-speed execution of a calculation that obtains a rendering image obtained by looking down at a polygon arranged in the virtual space in the direction of a predetermined line of sight.

  Further, the CPU 101 and the image arithmetic processor cooperate to draw a character string as a two-dimensional image in the frame memory or draw it on the surface of each polygon according to the font information that defines the character shape. It is.

  The NIC 109 is used to connect the information processing apparatus 100 to a computer communication network (not shown) such as the Internet, and is based on the 10BASE-T / 100BASE-T standard used when configuring a LAN (Local Area Network). Or modems that connect to the Internet using telephone lines, ISDN (Integrated Services Digital Network) modems, ADSL (Asymmetric Digital Subscriber Line) modems, and cables that connect to the Internet using cable television lines A modem or the like, and an interface (not shown) that mediates between them and the CPU 101 are configured.

  The audio processing unit 110 converts audio data read from the DVD-ROM into an analog audio signal and outputs the analog audio signal from a speaker (not shown) connected thereto. Further, under the control of the CPU 101, sound effects and music data to be generated during the progress of the game are generated, and sound corresponding to this is output from the speaker.

  When the sound data recorded on the DVD-ROM is MIDI (Musical Instrument Digital Interface) data, the sound processing unit 110 refers to the sound source data included in the sound data and converts the MIDI data into PCM (Pulse Code Modulation) data. Convert. If the compressed audio data is in ADPCM (Adaptive Differential PCM) format or Ogg Vorbis format, it is expanded and converted to PCM data. The PCM data can be output by performing D / A (Digital / Analog) conversion at a timing corresponding to the sampling frequency and outputting it to a speaker.

  The mat type controller 111 is connected via the interface 104. In the present invention, it is also possible to connect a plurality of mat type controllers 111 to the information processing apparatus 100. The mat-type controller 111 receives an operation input performed by the player when playing the game. FIG. 3 is an explanatory diagram showing the appearance of the mat-type controller 111. Hereinafter, the mat type controller 111 will be described with reference to FIG.

The foot objects FO1 and FO5 and the arm objects AO1 and AO5 move on the moving lane La1, the foot objects FO2 and FO6, and the arm objects AO2 and AO6 move on the moving lane La2, and the foot objects FO3, FO7, The arm objects AO3 and AO7 move on the movement lane La3, and the leg objects FO4 and FO8 and the arm objects AO4 and AO8 move on the movement lane La4. These leg objects FO1 to FO8 and arm objects AO1 to AO8 appear from the lower ends (starting points) of the movement lanes La1 to La4, move upward in the movement lanes La1 to La4, and the upper ends of the movement lanes La1 to La4 ( It disappears at the end point.
The number of moving lanes is not limited to four, and may be three or less or five or more. Further, the combination of the foot objects FO1 to FO8 and the arm objects AO1 to AO8 moving on the same movement lanes La1 to La4 is not limited to the above example, and any combination is possible.

  A predetermined area (determination area JA) is displayed on the game image of the dance game. The player shows the foot objects FO1 to FO8 at the timing when the centers of the foot objects FO1 to FO8 and the arm objects AO1 to AO8 overlap the determination line JL passing through the center of the determination area JA (hereinafter referred to as “overlap timing”). It is required to step in the direction or to swing the arm in the direction indicated by the arm objects AO1 to AO8. Specifically, the following operations are required.

It is required to press the button 111R at the timing when the center of the foot object FO1 overlaps the determination line JL.
It is required to press the button 111D at the timing when the center of the foot object FO2 overlaps the determination line JL.
It is required to press the button 111U at the timing when the center of the foot object FO3 overlaps the determination line JL.
It is required to press the button 111L at the timing when the center of the foot object FO4 overlaps the determination line JL.
It is required to press the button 111RD at the timing when the center of the foot object FO5 overlaps the determination line JL.
It is required to press the button 111RU at the timing when the center of the foot object FO6 overlaps the determination line JL.
It is required to press the button 111LU at the timing when the center of the foot object FO7 overlaps the determination line JL.
It is required to press the button 111LD at the timing when the center of the foot object FO8 overlaps the determination line JL.

At the timing when the center of the arm object AO1 overlaps the determination line JL, it is required to swing the controller 105a in the right direction (direction 301).
It is required to swing the controller 105a downward (direction 302) at the timing when the center of the arm object AO2 overlaps the determination line JL.
It is required to swing the controller 105a upward (direction 303) at the timing when the center of the arm object AO3 overlaps the determination line JL.
At the timing when the center of the arm object AO4 overlaps the determination line JL, it is required to swing the controller 105a in the left direction (direction 304).
At the timing when the center of the arm object AO5 overlaps the determination line JL, it is required to swing the controller 105a in the lower right direction (direction 305).
At the timing when the center of the arm object AO6 overlaps the determination line JL, it is required to swing the controller 105a in the upper right direction (direction 306).
It is required to swing the controller 105a in the upper left direction (direction 307) at the timing when the center of the arm object AO7 overlaps the determination line JL.
At the timing when the center of the arm object AO8 overlaps the determination line JL, it is required to swing the controller 105a in the lower left direction (direction 308).

  The player takes steps in the direction indicated by the foot objects FO1 to FO8 at the overlapping timing (the buttons 111L, 111R, 111U, 111D, 111LU, 111RU, 111LD, and 111RD are pressed) or the directions indicated by the arm objects AO1 to AO8. If the arm is shaken (the controller is shaken in directions 301 to 308), the score is added, and the score is displayed on the screen as "123400" in FIG. 4, for example. On the other hand, when there is no input by the player at the overlapping timing, when the step is not stepped in the direction indicated by the foot objects FO1 to FO8, or when the arm is not shaken in the direction indicated by the arm objects AO1 to AO8 No score is obtained or the score is subtracted. Note that a higher score may be obtained as the error between the timing of stepping and swinging the arm and the overlapping timing is smaller.

(Embodiment 1)
The game device according to the first embodiment changes the target form when the type of operation assigned to the target and the type of operation performed by the player do not match at the timing at which the type of operation assigned to the target is to be performed.
As shown in FIG. 5, the game device 200 according to the first embodiment includes a display unit 201, a reception unit 202, a determination unit 203, and a change unit 204.

The display unit 201 displays an aim and a plurality of targets on the screen, and each of the plurality of targets is assigned a type of operation to be performed by the player, and a timing at which the player should perform the operation of the allocated type. And display so that the aim and the target overlap. For example, in the game image of FIG. 4, the aim is the determination line JL, and the plurality of targets are the foot objects FO1 to FO8 and the arm objects AO1 to AO8. Assume that the color of the leg objects FO1 to FO8 and the arm objects AO1 to AO8 is usually white. The display unit 201 displays the determination line JL, the foot objects FO1 to FO8, and the arm objects AO1 so that the centers of the foot objects FO1 to FO8 and the arm objects AO1 to AO8 overlap the determination line JL at a timing when the player should perform an operation. AO8 is displayed on the screen.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the display unit 201.

The accepting unit 202 accepts an operation by the player. That is, information on the direction of steps that the player steps on, the direction in which the player swings his arm, and the timing of these operations is received.
Therefore, the CPU 101, the controller unit 105, and the mat type controller 111 work together to function as the receiving unit 202.

For each target, the determination unit 203 determines whether or not the accepted operation type matches the operation type assigned to the target that overlaps the aim at the timing when the target overlaps the aim (duplication timing). Determine whether. That is, the determination unit 203 determines whether or not the direction indicated by the foot objects FO1 to FO8 and the arm objects AO1 to AO8 whose centers overlap the determination line JL matches the step direction and the arm swing direction by the player. To do.
Therefore, the CPU 101 functions as the determination unit 203.

For example, as shown in FIG. 6, it is assumed that the foot objects FO4 _{1 to} FO4 ₃ and FO8 ₁ are displayed on the screen. At the timing when the center of the foot object FO4 ₁ is overlapped on the judgment line JL, when the player presses a button 111L, that is, if the step in the direction to be operated in overlapping timing is depressed (hereinafter, the object to be operating If the player performs an operation for, given the diagonal lines in the object), the determination unit 203 determines the direction of the stepped on by the player at overlapping timing step, and the direction indicated by the foot object FO4 ₁ matches. On the other hand, at the timing when the center of the foot object FO4 ₁ is overlapped on the judgment line JL, for example, when pressing the button 111R, that is, if the step in the direction to be operated in overlapping timing is not stepped on, the determination section 203, determines the direction of the stepped on by the player at overlapping timing step, and did not match the direction indicated by the foot object FO4 _1. Further, as shown in FIG. 7, after the center of the foot object FO4 ₁ has passed the judgment line JL, even when the player presses a button 111L, judgment unit 203, the direction of the steps by the player, the foot object FO4 ₁ It is determined that the direction indicated by does not match.

The change unit 204 overlaps the aim when the determination unit 203 determines that the type of operation assigned to the target overlapped with the aim does not match the type of operation performed by the player at the timing when the target overlaps the aim. The shape of the target to which the same operation type as that assigned to the target is assigned is changed. Here, the form is, for example, the color attached to the target or the size of the target. That is, the changing unit 204 determines that the direction indicated by the foot object FO1 to FO8 or the arm object AO1 to AO8 whose center is overlapped with the determination line JL does not match the direction of the player's operation, or the foot object FO1 to FO8 or the arm. The color and size attached to the objects AO1 to AO8 are changed.
Therefore, the CPU 101 functions as the changing unit 204.

An example in which the color applied to the target is changed is shown in FIG. For example, when the player presses the button 111L after the center of the foot object FO4 ₁ passes the determination line JL (FIG. 7), the determination unit 203 determines the type of operation assigned to the foot object FO4 ₁ and the player. It is determined that the operation types do not match. Then, the changing unit 204 changes the color of the foot objects FO4 _{1 to} FO4 ₃ displayed in the screen to black as shown in FIG. Since the foot object FO8 ₁ and the arm object AO2 ₁ are not objects that instruct the same action as the foot object FO4 _{1 that} is the determination target by the determination unit 203, the changing unit 204 does not change the color of these objects.

An example in which the size of the target is changed is shown in FIG. For example, when the player presses the button 111L after the center of the foot object FO4 ₁ passes the determination line JL (FIG. 7), the changing unit 204 displays the size of the foot objects FO4 _{1 to} FO4 ₃ displayed on the screen. As shown in FIG. 9, the size is made larger than the sizes of the foot objects FO4 _{1 to} FO4 ₃ before the determination by the determination unit 203.

In addition, when the determining unit 203 determines that the operation type assigned to the target whose form has been changed matches the operation type of the player, the changing unit 204 is based on the changed target form. return. For example, as illustrated in FIG. 10, it is assumed that black is attached to the foot objects FO4 _{2 to} FO4 ₄ that are requested to step in the left direction. Player, if the center of the foot object FO4 ₂ presses the button 111L at overlapping timing judgment line JL, judgment unit 203, the type of operations assigned to the foot object FO4 _2, the type of operation by the player matches Judge that. In this case, as shown in FIG. 11, the object FO4 ₂ the type is determined to match the operation is erased, the changing unit 204, black is attached leg object _FO4 3, FO4 ₄ back to the original white. On the other hand, the player, if the center of the foot object FO4 ₂ presses the button 111R at overlapping timing judgment line JL, judgment unit 203, the type of operations assigned to the foot object FO4 _2, the player's operation It is determined that the types do not match. In this case, the changing unit 204 is not returned to the original color of the foot object _FO4 3, FO4 _4, legs objects _FO4 3, FO4 ₄ is displayed while keeping black attached.

(Operation of game device)
Hereinafter, operations performed by each unit of the game apparatus 200 according to the present embodiment will be described. When the game apparatus 200 is powered on, the CPU 101 starts a game control process shown in the flowchart of FIG.

First, the CPU 101 reads out data related to the game image from the DVD-ROM to the RAM 103 and initializes it (step S101).
Next, the image processing unit 107 generates a game image based on the read data, and the display unit 201 waits until a vertical synchronization interrupt occurs (step S102).

  When vertical synchronization occurs, the display unit 201 displays the game image on the screen so that the aim and the target overlap with each other at the timing when the player should perform the operation (step S103). For example, as shown in the game image of FIG. 4, the display unit 201 displays the center of the foot objects FO1 to FO8 and the arm objects AO1 to AO8 so as to overlap the determination line JL at the timing of requesting an operation from the player.

  The receiving unit 202 determines whether or not an operation by the player has been received (step S104). When the receiving unit 202 determines that the operation by the player has been received (step S104; Yes), the determining unit 203 determines whether it is the timing at which the current operation should be performed, that is, whether or not the target overlaps the aim (see FIG. Step S105). On the other hand, also when the receiving unit 202 determines that the operation by the player has not been received (step S104; No), the determining unit 203 determines whether the current timing should be the operation, that is, whether the target overlaps the aim. Is determined (step S110).

  For example, when the reception unit 202 receives information related to pressing of the button 111L by the player, the determination unit 203 determines whether the center of any object overlaps the current determination line JL. On the other hand, even when the reception unit 202 does not receive information on pressing of any button or arm swing by the player, the determination unit 203 determines whether the center of any object overlaps the current determination line JL. .

  If it is determined in step S105 that it is time to perform the operation (step S105; Yes), the determination unit 203 receives the type of operation assigned to the target overlapping the aim and the reception unit 202. It is determined whether or not the type of operation performed matches (step S106). When the determination unit 203 determines that the type of operation assigned to the target overlapping the aim and the type of operation received by the reception unit 202 are identical (step S106; Yes), the CPU 101 determines a predetermined score. Is added to the score of the player (step S107).

For example, as shown in FIG. 6, at the timing when the center of the foot object FO4 ₁ is overlapped on the judgment line JL, when the player presses the button 111L, the determination unit 203 assigned to the target overlaps the aiming operation And the type of operation received by the receiving unit 202 are determined to match. Then, the CPU 101 adds a predetermined score to the score of the player, and the score after the addition is displayed on the screen as “123400” in FIG.

  After the points are added, the changing unit 204 determines whether or not the form of the target determined to match in step S106 has already been changed (step S108). When the change unit 204 determines that the form of the target has been changed (step S108; Yes), the change unit 204 restores the form of the target (step S109). Then, after the target form is restored, the process returns to step S102. On the other hand, when the changing unit 204 determines that the form of the target is not changed (step S108; No), the process returns to step S102.

For example, at the timing when the center black foot object FO4 _2, labeled in FIG. 8 overlaps the judgment line JL, when the player presses the button 111L (FIG. 10), the changing unit 204, foot object FO4 ₂ is It is determined that the form (color) has been changed, and the color is returned to the original color (white) as shown in FIG. Then, the process returns to step S102. On the other hand, when the foot object FO4 ₁ in FIG. 6, the changing unit 204 determines that not intended form (color) is changed, the flow returns to step S102.

On the other hand, if it is determined in step S104 that the operation has been accepted from the player but it is not the time to perform the operation, that is, the player steps on the step when the target is not over the aim (step S105; No). The changing unit 204 is a target to which the same type of operation as the target is assigned, and changes the form of the target displayed on the screen (step S111). And after the form of a target is changed, it returns to step S102.
In step S105, it is determined that the timing at which the operation is received from the player matches the timing at which the operation should be performed, but the type of operation of the player does not match the type of operation assigned to the target. In other words, when the step is taken at the timing when the target overlaps the aim, but when the step is taken in a direction other than the direction indicated by the target (step S106; No), the changing unit 204 is of the same type as the target. The target to which the operation is assigned and the form of the target displayed on the screen is changed (step S111). And after the form of a target is changed, it returns to step S102.
Further, in step S104, no operation is accepted from the player, but if the current timing is the timing at which the operation should be performed, that is, the target is currently on the aim, but the player has not performed any operation. In the case (step S110; Yes), the changing unit 204 is a target to which the same type of operation as the target is assigned, and changes the form of the target displayed on the screen (step S111). And after the form of a target is changed, it returns to step S102. On the other hand, if the operation is not accepted from the player in step S104 and the current timing is not the timing at which the operation should be performed, that is, the player does not perform any operation and the current target does not overlap the aim (step S104). S110; No), it returns to step S102.

For example, when the accepting unit 202 accepts pressing of the button 111L by the player but the center of the foot object FO4 does not overlap the determination line JL at the time of pressing (step S105; No), that is, as shown in FIG. As described above, when the player presses the button 111L after the center of the foot object FO4 ₁ passes the determination line JL, the changing unit 204 is a color attached to the foot objects FO4 _{1 to} FO4 ₃ as shown in FIG. From the original white to black. Alternatively, as illustrated in FIG. 9, the changing unit 204 increases the size of the foot objects FO4 _{1 to} FO4 ₃ than the original size. After the changing unit 204 changes the color and size of the foot objects FO4 _{1 to} FO4 ₃ , the process returns to step S102.

Further, for example, at the timing when the center of the foot object FO4 ₁ is overlapped on the judgment line JL, when the player presses a button 111R (step S106; No), or the center of the foot object FO4 ₁ is overlapped on the judgment line JL If the player does not press any button at the timing (step S110; Yes), the changing unit 204, as shown in FIG. 8 or FIG. 9, is a color or size assigned to the foot objects FO4 _{1 to} FO4 ₃ Change the height. Then, the process returns to step S102. On the other hand, as shown in FIG. 11, when neither the foot object nor the arm object overlaps the determination line JL and the player does not press the button or swing the arm, the process returns to step S102.

  According to the present embodiment, even if a plurality of types of targets are displayed on the screen, a target that is misoperated by the player is displayed in a different form from other targets. Can do.

(Embodiment 2)
The game device of the second embodiment changes the target form based on the difference between the timing at which the operation should be performed and the timing of the operation by the player.
As shown in FIG. 5, the game device 200 according to the second embodiment includes a display unit 201, a reception unit 202, a determination unit 203, and a change unit 204. The display unit 201, the reception unit 202, and the determination unit 203 of the present embodiment have the same functions as those of the first embodiment. Hereinafter, the changing unit 204 having different functions will be described.

When the determination unit 203 determines that the type of operation assigned to the target that has overlapped the aim does not match the type of operation by the player at the timing when the target has overlapped with the aim, the changing unit 204 targets the aim Is determined (hereinafter referred to as “timing difference”) between the timing at which the operations overlap (timing for performing the operation) and the timing at which the operation is received by the receiving unit 202. Then, the changing unit 204 changes the form of the target to which the same operation type as the operation type assigned to the target overlapped with the aim is based on the obtained difference.
Therefore, the CPU 101 functions as the changing unit 204.

For example, the changing unit 204 changes the lightness of the color attached to the target from the obtained timing difference according to the graph shown in FIG. In the following, it is assumed that the target color is expressed in gray scale. Further, FIG. 14 shows an example of the foot object FO4 and the arm object AO4 in which the brightness is changed according to the graph of FIG.
In the graph of FIG. 13, when the timing difference is “0 second”, the brightness is obtained as “100%”. Therefore, the changing unit 204 adds white to the target as in the foot object FO4 and the arm object AO4 in FIG. In the case of the arm objects AO1 to AO8, the color of only the arrow symbol in the square is changed.
Further, when the timing difference is “1 second”, the brightness is obtained as “50%”. Therefore, the changing unit 204 adds gray to the target as in the foot object FO4 and the arm object AO4 in FIG.
When the timing difference is “2 seconds”, the brightness is obtained as “0%”. Therefore, the changing unit 204 adds black to the target as in the foot object FO4 and the arm object AO4 in FIG.
Then, when the timing difference is greater than “2 seconds”, the changing unit 204 adds black to the target.

For example, it is assumed that the controller 105a is swung in the direction 302 by the player one second after the timing when the center of the arm object AO2 ₁ in FIG. 11 overlaps the determination line JL, that is, the timing when the arm is swung downward. In this case, the changing unit 204, as shown in FIG. 15, the arm object AO2 ₂ displayed on the screen after the arm object AO2 ₁ denoted by the gray of FIG. 14 (b). On the other hand, it is assumed that the button 111L is pressed by the player two seconds after the timing when the center of the foot object FO44 ₄ in FIG. 11 overlaps the determination line JL, that is, the timing when the step should be taken to the left. In this case, as illustrated in FIG. 15, the changing unit 204 adds black color to the foot objects FO4 _{5 to} FO4 ₇ displayed on the screen after the foot object FO4 ₄ . Note that the foot object FO4 ₅ is displayed on the screen in a state where the foot object FO4 ₅ overlaps with the determination line JL and is black even after passing through the determination line JL because the step is not stepped leftward. Has been.

For example, the changing unit 204 may change the size of the target from the obtained timing difference according to the graph shown in FIG.
In the graph of FIG. 16, when the timing difference is “0 seconds”, that is, when an operation by the player is performed at the timing at which the operation should be performed, the changing unit 204 displays the foot object FO4 and the arm of FIG. Like the object AO4, the target size is set to “0”. The size “0” is the minimum value of the target size, and it is assumed that all the targets are size “0” at the start of the game.
When the timing difference is “1 second”, the changing unit 204 sets the target size to “5” and the timing difference to “2 seconds” as in the foot object FO4 and the arm object AO4 in FIG. ", The target size is set to" 10 "as in the leg object FO4 and the arm object AO4 in FIG. Then, when the timing difference is greater than “2 seconds”, the changing unit 204 sets the target size to “10”. The size “10” is the maximum value of the target size, and the size “5” is the median value of the target size.

For example, it is assumed that the controller 105a is swung in the direction 302 by the player one second after the timing when the center of the arm object AO2 ₁ in FIG. 11 overlaps the determination line JL, that is, the timing when the arm is swung downward. In this case, as shown in FIG. 18, the changing unit 204 changes the size of the arm object AO2 ₂ displayed on the screen after the arm object AO2 ₁ to “5”. On the other hand, it is assumed that the button 111L is pressed by the player two seconds after the timing when the center of the foot object FO44 ₄ in FIG. 11 overlaps the determination line JL, that is, the timing when the step should be taken to the left. In this case, the changing unit 204 changes the size of the foot objects FO4 _{5 to} FO4 ₇ to “10” as shown in FIG. Incidentally, the foot object Fo8 ₃ and arms object AO6 ₁ of FIG 18 has a size "0". In addition, the foot object FO4 ₅ is not set in the left direction at the timing when the foot object FO4 ₅ is overlapped with the determination line JL, so that the size is set to “10” even after passing through the determination line JL. It is displayed on the screen.

(Operation of game device)
Hereinafter, operations performed by each unit of the game apparatus 200 according to the present embodiment will be described. When the game apparatus 200 is powered on, the CPU 101 starts a game control process shown in the flowchart of FIG. In the flowchart of FIG. 19, steps having the same step numbers as in FIG. 12 perform the same processing as the processing in the flowchart of FIG.

  If it is determined in step S104 that the operation has been received from the player but it is not the time to perform the operation (step S105; No), the changing unit 204 performs the operation at the timing when the receiving unit 202 has received the operation. A timing difference from the power timing is obtained, and the target form is changed based on the difference (step S212). And after the form of a target is changed, it returns to step S102.

For example, if the button 111L is pressed by the player 2 seconds after the timing to step to the left, the changing unit 204 obtains the brightness “0%” from the timing difference “2 seconds” according to the graph of FIG. The foot object FO4 displayed on the screen is changed from white to black (FIG. 15, foot objects FO4 _{5 to} FO4 ₇ ). Then, the process returns to step S102.

  Further, when it is determined in step S104 that the operation by the player has not been accepted (step S104; No), the determination unit 203 has passed a predetermined time or more from the timing at which the target has recently overlapped the aim (timing to perform the operation). It is determined whether or not it has been done (step S210). If the target has overlapped with the aim and has passed for a certain period of time, it is considered that the target has not been operated. Therefore, when the predetermined time or more has elapsed (step S210; Yes), the changing unit 204 determines the type of operation assigned to the target and the type of operation by the player at the timing when the target overlaps the aim by the determining unit 203. Are determined not to match, the target form is changed to a predetermined form (step S211). And after the form of a target is changed, it returns to step S102. On the other hand, when the determination unit 203 determines that the predetermined time has not elapsed (step S210; No), the process returns to step S102.

  For example, the predetermined time is “2 seconds”. When the receiving unit 202 does not receive any operation from the player and the determining unit 203 determines that 2 seconds have passed since the center of the foot object FO4 overlapped the determination line JL most recently, the determining unit 203 determines that the foot object FO4 It is determined that the type of operation indicated by does not match the type of operation by the player. Then, the changing unit 204 adds a predetermined color (for example, black) to the foot object FO4. Then, the process returns to step S102. On the other hand, if the receiving unit 202 has not received any operation from the player, but two seconds have not yet elapsed since the center of the foot object FO4 overlapped the determination line JL most recently, the process returns to step S102, and the display unit continues. A game image is displayed in 201, and it is determined whether or not a player's operation is received by the receiving unit 202.

  According to the present embodiment, it is possible to change the form of the target based on the shift in the operation timing by the player.

(Embodiment 3)
The game device according to the third embodiment changes the form of the target based on the difference between the type of operation assigned to the target and the type of operation by the player.
As shown in FIG. 5, the game device 200 according to the third embodiment includes a display unit 201, a reception unit 202, a determination unit 203, and a change unit 204. The display unit 201, the reception unit 202, and the determination unit 203 of the present embodiment have the same functions as those of the first embodiment. Hereinafter, the changing unit 204 having different functions will be described.

The change unit 204 overlaps the aim when the determination unit 203 determines that the type of operation assigned to the target overlapped with the aim does not match the type of operation performed by the player at the timing when the target overlaps the aim. The type of target assigned the same type of operation as that assigned to the target is changed based on the difference between the type of operation assigned to the target that overlaps the aim and the type of operation by the player Let
Therefore, the CPU 101 functions as the changing unit 204.

For example, the difference in the type of operation is obtained as follows.
First, as shown in FIG. 20, the objects with the directions indicated by the foot objects FO1 to FO8 opposite to each other by 180 degrees are arranged on a diagonal line. Here, the angle formed by the directions of adjacent objects is assumed to be 45 degrees. For example, on the basis of the foot object FO3, the angle 401 formed by the foot object FO3 and the foot object FO7 and the angle 401 ′ formed by the foot object FO3 and the foot object FO6 are “45 degrees”, and the foot object FO3 and the foot object FO4 The angle 402 formed between the foot object FO3 and the foot object FO1 is “90 °”, the angle 403 formed between the foot object FO3 and the foot object FO8, and the angle 403 ′ formed between the foot object FO3 and the foot object FO5. Is “135 degrees”, and the angle 404 formed by the foot object FO3 and the foot object FO2 is “180 degrees”.

It is assumed that the difference in the type of operation increases as the angle between the objects arranged as described above (hereinafter referred to as “angle difference”) increases.
For example, it is assumed that the changing unit 204 obtains the brightness of the color attached to the target according to the graph shown in FIG. 21 and changes the color of the target.
When the angle difference is “90 degrees”, for example, when the center of the foot object FO3 overlaps the determination line JL and the player presses the button 111L (the direction indicated by the foot object FO4) at this timing, the changing unit 204 The brightness of the color attached to the object FO3 is changed to “50%”.
Alternatively, when the angle difference is “180 degrees”, for example, when the center of the foot object FO3 overlaps the determination line JL and the player presses the button 111D (the direction indicated by the foot object FO2) at this timing, the changing unit 204 The brightness of the color attached to the foot object FO3 is changed to “100%”.

  As for the arm object, the arrow objects in the square are arranged as shown in FIG. 20, and the angle difference is obtained similarly.

(Operation of game device)
Hereinafter, operations performed by each unit of the game apparatus 200 according to the present embodiment will be described. When the game apparatus 200 is powered on, the CPU 101 starts a game control process shown in the flowchart of FIG. In the flowchart of FIG. 22, steps having the same step numbers as those in FIG. 12 or 19 perform the same processing as the processing in the flowchart of FIG. 12 or 19.

When it is determined in step S105 that the timing at which the operation is received from the player matches the timing at which the operation should be performed, but the type of operation of the player does not match the type of operation assigned to the target ( Step S106; No), the changing unit 204 changes the form of the target based on the difference between the type of operation assigned to the target and the type of operation of the player (Step S312). And after the form of a target is changed, it returns to step S102.
For example, when the center of the foot object FO3 overlaps the determination line JL and the player presses the button 111L (the direction indicated by the foot object FO4) at this timing, the changing unit 204 sets the angle difference between the target and the operation to “90 degrees. ”And the lightness of the color attached to the foot object FO3 is changed to“ 50% ”based on the graph of FIG. Then, the process returns to step S102.

  According to this embodiment, the form of the target can be changed based on the difference between the type of operation required and the type of operation of the player.

(Embodiment 4)
When there are a plurality of types of targets whose form should be changed in the first embodiment, the game device of the fourth embodiment changes the target form based on the number of targets for each type.
As shown in FIG. 5, the game device 200 according to the fourth embodiment includes a display unit 201, a reception unit 202, a determination unit 203, and a change unit 204. The display unit 201, the reception unit 202, and the determination unit 203 of the present embodiment have the same functions as those of the first embodiment. Hereinafter, the changing unit 204 having different functions will be described.

The change unit 204 overlaps the aim when the determination unit 203 determines that the type of operation assigned to the target overlapped with the aim does not match the type of operation performed by the player at the timing when the target overlaps the aim. The shape of the target to which the same operation type as that assigned to the target is assigned is changed. Then, when there are a plurality of types of targets whose form is to be changed, the changing unit 204 increases the degree of change in the form as the number of targets of that type increases. That is, the change unit 204 is a target of the same type as the target that is determined not to match the type of operation performed by the player by the determination unit 203, and is the target displayed after the determination is made until the end of the dance game. The greater the remaining number, the greater the degree of change in form.
Therefore, the CPU 101 functions as the changing unit 204.

For example, when there are a plurality of targets whose form is to be changed, the changing unit 204 changes the brightness of the color attached to the target based on the remaining number of targets according to the graph shown in FIG. In the following, it is assumed that the target color is expressed in gray scale. FIG. 14 shows an example of the foot object FO4 and the arm object AO4 whose brightness is changed according to the graph of FIG.
In the graph of FIG. 23, when the remaining number of targets is “1”, the lightness is calculated as “100%”. Therefore, the changing unit 204 adds white to the target as in the foot object FO4 and the arm object AO4 in FIG. In the case of AO8, only the color of the arrow symbol in the square is changed.
When the remaining number of targets is “20”, the brightness is calculated as “50%”. Therefore, the changing unit 204 adds gray to the target as in the foot object FO4 and the arm object AO4 in FIG.
Further, when the remaining number of targets is “40”, the brightness is calculated as “0%”. Therefore, the changing unit 204 adds black to the target as in the foot object FO4 and the arm object AO4 in FIG.
And the change part 204 attaches black to a target, when there are more remaining numbers of targets than "40".

For example, the center of the arm object AO2 ₁ in FIG. 11 is a timing overlapping the judgment line JL, i.e., the controller 105a by the player at the timing of swinging the arm downward is not swung in the direction 302. Then, after the arm object AO2 ₁ is displayed on the screen, the number of arm objects AO2 _m (m: arbitrary) displayed on the screen before the end of the dance game is 20. The center of the foot object FO4 ₄ in FIG. 11 is a timing overlapping the judgment line JL, i.e., the buttons 111L by the player at a timing to take steps to the left is not pressed. Then, after the foot object FO4 ₄ is displayed on the screen, the number of foot objects FO4 _n (n: arbitrary) displayed on the screen before the end of the dance game is 40. In this case, as shown in FIG. 15, the changing unit 204 adds the gray color shown in FIG. 14B to the arm object AO2 ₂ displayed on the screen after the arm object AO2 ₁ , and after the foot object FO4 ₄ . The leg objects FO4 _{5 to} FO4 ₇ displayed on the screen are black.
In the present embodiment, the changing form is a color. However, the present invention is not limited to this, and the size of the target may be changed as shown in the example of FIG.

(Operation of game device)
Hereinafter, operations performed by each unit of the game apparatus 200 according to the present embodiment will be described. When the game apparatus 200 is powered on, the CPU 101 starts a game control process shown in the flowchart of FIG. In the flowchart of FIG. 24, steps having the same step numbers as those in FIG. 12 or FIG. 19 perform the same processing as the processing in the flowchart of FIG.

  In step S105, when the player steps on the target when the target is not over the aim (step S105; No), the step is performed at the timing when the target is over the aim in step S105. When the step is taken (step S106; No), or when the target is currently on the aim but the player does not perform any operation (step S110; Yes), the changing unit 204 It is determined whether there is a target whose form is changed other than the target, that is, whether there are a plurality of targets whose form is changed (step S412). When it is determined that there are a plurality of targets whose form is to be changed (step S412; Yes), the changing unit 204 changes the form according to the remaining number of targets of each type (step S413). And after the form of a target is changed, it returns to step S102. On the other hand, when the change unit 204 determines that there are not a plurality of targets whose form is to be changed (step S412; No), the change unit 204 changes the form of the target to a predetermined form (step S211). And after a target is changed into a predetermined form, it returns to Step S102.

For example, the controller 105a by the player at the timing when the center of the arm object AO2 ₁ in FIG. 11 are overlapped in the judgment line JL is not swung in the direction 302, then the timing of the center of the foot object FO4 ₄ in FIG. 11 are overlapped in the judgment line JL Assume that the button 111L is not pressed by the player. Assume that the number of arm objects AO2 _m displayed on the screen after the arm object AO2 ₁ is 20, and the number of foot objects FO4 _n displayed on the screen after the foot object FO4 ₄ is 40. In this case, as shown in FIG. 15, the changing unit 204 adds the gray color shown in FIG. 14B to the arm object AO2 ₂ displayed on the screen after the arm object AO2 ₁ , and after the foot object FO4 ₄ . The leg objects FO4 _{5 to} FO4 ₇ displayed on the screen are black. Then, the process returns to step S102. On the other hand, the controller 105a center of the arm object AO2 ₁ is the player at the timing of overlapping the judgment line JL in FIG. 11 is swung in the direction 302, then the center of the foot object FO4 ₄ in FIG. 11 are overlapped in the judgment line JL timing in the case where the button 111L is not pressed by the player, the changing unit 204, subjected to predetermined color only the foot object _FO4 5 _{~FO4 7} displayed on the screen after the foot object FO4 ₄ (e.g., black). Then, the process returns to step S102.

  According to the present embodiment, it is possible to increase the number of operation errors by increasing the degree of change of the form and making it easier to recognize a target that is displayed more frequently on the screen after an operation error. Can be prevented.

  According to the present invention, it is possible to provide a game device, a game control method, and a program that are suitable for making it easier for the player to determine the types of targets that are sequentially presented.
