Description

  The present invention relates to a game apparatus, a game control method, and a program for realizing these on a computer, which are suitable for presenting a timing at which a user should perform an operation.

  A so-called music game (rhythm game) operated by a user in accordance with a music rhythm is known. A music game is, for example, a game that progresses when a user operates with good timing when guide images sequentially displayed on a screen reach a reference image (see, for example, Patent Document 1). When the guide image reaches the vicinity of the reference image, when the user performs an operation corresponding to the guide image, the guide image disappears from the screen (see, for example, Patent Document 1, paragraphs 0053 to 0059 and FIG. 3). . In Patent Document 1, a message (for example, “GREAT”, “GOOD”, etc.) associated with the input timing of the user is displayed on the screen.

JP 2001-222280 A

  However, when the display range for displaying a guide image or the like is limited as in a mobile phone or a portable game device, when a plurality of guide images are displayed on the screen, the display of each guide image is small. In some cases, there are users who find it difficult to view the guidance image. On the other hand, in a normal rhythm game, it may be difficult to see if the viewing position in the screen moves greatly when the user knows the timing to operate. Therefore, there is a demand for a technique for presenting the timing to be operated to the user in an easy-to-understand manner.

  The present invention has been made in view of the above problems, and provides a game device, a game control method, and a program for realizing these on a computer, which are suitable for presenting a timing at which a user should perform an operation. The purpose is to do.

  In order to achieve the above object, a game device according to a first aspect of the present invention includes a display unit, a detection unit, and a determination unit.

  First, the display unit moves the guide image from the first position to the second position at a predetermined speed, and then moves the guide image from the second position to the first position at the predetermined speed. The moving image to be displayed is displayed on the screen.

Here, the first position and the second position are arbitrary positions on the screen. Since the guide image moves between the first position and the second position, both positions are typically separated by a certain distance or more.
A guidance image is an arbitrary image for prompting the user to perform an operation.
The predetermined speed is preferably equal speed, but the speed may be variable. The speed at which the guide image moves from the first position to the second position may be different from the speed at which the guide image moves from the second position to the first position.

  The guide image appears from the first position, follows a predetermined route, and moves to the second position. When the guide image reaches the second position, the guide image stays at the second position for a predetermined time, and moves to the first position along a predetermined route. Then, when the guide image reaches the first position, it disappears from the screen.

  Note that the route through which the guide image moves from the first position to the second position and the route through which the guide image moves from the second position to the first position are typically the same, but may be different. Good.

  Next, a detection part detects the state of the operation body which will be in any one of a 1st state and a 2nd state by a user's operation.

Here, the operating body refers to a device for accepting an input operation from the user, and corresponds to, for example, a touch panel, a controller, a keyboard, a mouse, and the like.
The first state refers to a state where there is no input operation from the user, or a state where the input operation specified by the user is not performed. The second state refers to a state in which an input operation designated by the user is being performed.

Next, the determination unit determines that the detected state of the operating body is
(A) While the guide image moves from the first position to the second position, the first state is maintained;
(B) While the guide image moves from the second position to the first position, the second state is maintained.
(C) when the guide image reaches the first position, the second state is shifted to the first state;
In this case, it is determined that the user's operation is successful.

  On the screen, there are a first position and a second position that are separated by a predetermined distance, and a guide image that moves between the two positions is displayed. The user confirms the timing of performing the input operation while visually recognizing the position of the guide image moving from the first position to the second position. Then, when the guide image reaches the second position, an input operation is requested. Specific examples of the input operation include touching if the operating body is a touch screen, and pressing the button if the operating body is a button. When a touch or the like is performed at the time, it is determined that the user's operation is successful.

  Next, the continuation of the input operation is requested until the guide image reaches the first position after reaching the second position. As a specific example of the continuation of the input operation, if the operating body is a touch screen, the user continues to touch, and if the operating body is a button, the button is continuously pressed. When the guide image reaches the first position, the input operation is requested to be released, that is, the touch release or the button press release is requested. When the touch is released at the time, it is determined that the user operation is successful.

  Even when the screen size is small and there is a possibility that the display range may be limited, such as a mobile phone or a portable game device, the user can cancel the touch of the second position where an operation such as a touch should be performed. The timing at which the operation should be performed can be confirmed simply by visually recognizing the guide image that reaches the two positions, i.e., the first position where the operation should be performed. Moreover, since the range in which the guidance image is displayed is limited between the first position and the second position, the movement of the user's line of sight can be reduced.

  For this reason, according to this invention, the timing which should be operated can be shown to a user in an easy-to-understand manner. In addition, by reducing the movement of the user's line of sight, the timing to be operated can be presented to the user in an easy-to-understand manner.

  The game device according to the present invention can also be configured to include an output unit.

  The output unit outputs a predetermined sound while the detected state of the operating body is in the second state.

  Here, the predetermined sound is sound composed of an arbitrary volume, pitch, tone color, and the like. When the user touches the touch screen, sound is output, and sound is continuously output while the user is touched. When the touch is released, the audio output is stopped. For this reason, when it is determined that the user's operation is successful, that is, until the guide image leaves the second position and reaches the first position after reaching the second position. When the operation of touching the screen is continued, sound is output.

  Thereby, it is possible to prompt the user to perform an operation of outputting sound.

Further, the screen and the operating body can be a touch screen.
On the touch screen,
(A) The state where the user is touching the range in which the guide image moves is the second state,
(B) The state where the user is touching outside the range where the guide image moves and the state where the user is not touching the touch screen are the first state.

  Here, the range in which the guide image moves typically refers to a region sandwiched between the first position and the second position. When the user touches the range in which the guidance image moves on the screen, the touch is determined as the designated operation. On the other hand, other than the range in which the guide image moves, for example, the state where the user is touching the outer peripheral area between the first position and the second position and the state where the user is not touching the touch screen are specified. It is determined that the operation is not performed.

  Thereby, it is possible to prompt the user to touch a predetermined position on the screen.

  Further, in the moving image, the color of the region sandwiched between the first position and the guide image may be different from the color of the region sandwiched between the second position and the guide image.

  For example, it is assumed that the area sandwiched between the first position and the guide image is displayed in the first color, and the area sandwiched between the second position and the guide image is displayed in the second color. In this case, as the guide image moves from the first position to the second position, the area displayed in the first color increases and the area displayed in the second color decreases. When the guide image reaches the second position, the entire area sandwiched between the first position and the second position is displayed in the first color. For this reason, the timing at which the entire region sandwiched between the first position and the second position is displayed in the first color is the timing at which the user should touch.

  When the guide image reaches the second position and then moves away from the second position to the first position, the area displayed in the first color decreases, and the second color is displayed. The displayed area increases. When the guide image reaches the first position, the entire region sandwiched between the first position and the second position is displayed in the second color. For this reason, the timing at which the entire region sandwiched between the first position and the second position is displayed in the second color is the timing at which the user should release the touch.

  Thus, the two regions are distinguished by the color change and the position of the guide image is clearly displayed on the screen, so that the timing for performing the operation can be presented to the user in an easy-to-understand manner.

  The display unit can also display on the screen a moving image in which a plurality of guide images move.

  For example, the first guide image moves between a first position and a second position, and the second guide image moves between a third position and a fourth position. Each guide image moves between any two positions on the screen. A guide image that moves between two positions that are separated by a predetermined distance is displayed on the screen, and a timing at which an operation such as a touch should be performed and a release operation such as a touch are performed according to the position of the guide image. The user can recognize the timing to be changed.

  Thereby, even in a limited display range, the timing to be operated can be presented to the user in an easily understandable manner.

  In order to achieve the above object, a game control method according to another aspect of the present invention is a game control method that is executed by a game device having a display unit, a detection unit, and a determination unit. A process, a detection process, and a determination process are provided.

  In the display step, the guide image moves from the first position to the second position at a predetermined speed, and then the guide image from the second position to the first position at the predetermined speed. The moving image is displayed on the screen.

  In the detection step, the detection unit detects the state of the operating body that is in one of the first state and the second state by a user operation.

  In the determination step, the detected state of the operating body is in the first state while (a) the guide image moves from the first position to the second position, and (b) the guide image is in the second position. In the case of the second state during the movement from the first position to the first position, and (c) when the guide image reaches the first position, the second state is shifted to the first state. However, it is determined that the operation of the user is successful.

  Thereby, the timing which a user should operate can be shown.

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

  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.

In addition, as a communication unit, for example, a NIC (Network Interface Controller) conforming to a standard such as 10BASE-T / 100BASE-T used when configuring a LAN (Local Area Network), a hard disk as a storage device, a DVD -ROM, magneto-optical disk, etc. can be used. In addition, a keyboard or a mouse is used as an input device instead of a touch panel. Then, after the program is installed, when the program is executed, it can function as a game device.

  In the present embodiment, a keyboard instrument such as an organ or Electone (registered trademark) will be described by taking as an example a game of playing a keyboard instrument in which sound is output while the key is being pressed. In the game of playing the keyboard instrument of the present embodiment, as shown in FIG. 2, a keyboard image (hereinafter, keyboard 23) is displayed on the second display unit 20. When the user touches the touch panel 21 on which the keyboard 23 is displayed with the touch pen 22 or a finger, a process based on the touch is performed. For example, when the user touches a key on the keyboard 23 with the touch pen 22, a sound corresponding to the touched key is output while being touched.

  3A and 3B are diagrams illustrating an example of a screen displayed on the second display unit 20. As shown in the figure, a keyboard 23 is displayed on the second display unit 20. The keyboard 23 typically includes a plurality of white key images (hereinafter, white keys 23a) and a plurality of black key images (hereinafter, black keys 23b). The first position 31 in the white key 23a and the black key 23b corresponds to the upper side of the white key 23a and the black key 23b (keyboard 23). Further, the second position 32a in the white key 23a corresponds to the lower side of the white key, and the second position 32b in the black key 23b corresponds to the lower side of the black key. Since the key shapes are different, the second positions 32a and 32b are different between the white key 23a and the black key 23b.

For example, as shown in FIG. 3A, the guide image 30 is an image formed in a line shape displayed on the white key 23a or the black key 23b. Further, as shown in FIG. 3B, the guide image 30 corresponds to a band-shaped image 30a formed in a band shape displayed on the white key 23a or the black key 23b, or a lower side portion of the band-shaped image 30a shown inside the dotted line. It is an image formed in a linear shape. The guide image 30 is an image formed from any shape and size that can be displayed on the white key 23a or the black key 23b.
Below, the guide image 30 is demonstrated as an image formed in the shape of a line corresponding to the lower side of the strip-shaped image 30a as shown in FIG. 3B.

The user advances the game by performing a touch operation and releasing the touch operation at an appropriate timing while checking the position of the guide image 30 for prompting the operation. 4A to 4E are diagrams for explaining the movement of the guide image 30. FIG. Hereinafter, the case where the guide image 30 moves in the white key 23a will be described with reference to FIG.
Note that the case where the guide image 30 moves in the black key 23b is the same as the case in which the guide image 30 moves in the white key 23a, and is omitted here.

  First, as shown in FIG. 4A, the keyboard 23 is displayed on the second display unit 20. The keyboard 23 includes a plurality of white keys 23a and a plurality of black keys 23b. When the user touches the white key 23a or the black key 23b with a finger or the like, a sound corresponding to the touched key is output. The guide image 30 appears from the first position 31 and moves along the white key 23a. Here, the movement typically refers to linearly moving between different positions. In the case of the figure, the guide image 30 advances linearly between the first position 31 and the second position 32a shown on the white key 23a. Note that the movement path is not limited to a straight line, and is arbitrary such as a wavy line or a zigzag line.

  Next, as shown in FIG. 4B, the guide image 30 moves from the first position 31 to the second position 32a along the white key 23a in synchronization with the rhythm of the music to be played. go. As the guide image 30 moves from the first position 31 to the second position 32a, an area 33 sandwiched between the first position 31 and the guide image 30 increases, and the second position 32a and the guide are guided. The area 34 sandwiched between the images 30 decreases. In the white key 23a on which the guide image 30 is displayed, a region 33 sandwiched between the first position 31 and the guide image 30 is typically given a color other than white. As a result, the color of the region 33 sandwiched between the first position 31 and the guide image 30 and the color of the region 34 sandwiched between the second position 32a and the guide image 30 are different. The position of can be clearly grasped.

  When the guide image 30 moves and the guide image 30 reaches the second position 32a, as shown in FIG. 4C, that is, the colors of all the areas 33 sandwiched between the first position 31 and the guide image 30. The time when changes occur is the timing when the user performs a touch operation. The user can grasp the key to be touched and the timing to touch by visually recognizing the color change of the keyboard 23. When the user touches the white key 23a whose color has changed with the touch pen 22 or the like, a sound corresponding to the white key 23a is output. For example, as shown in the figure, by touching the key corresponding to “Fa”, the sound of “Fa” is output. Voice is output while the user continues to touch. The guide image 30 starts moving again after staying at the second position 32a for a predetermined time. The predetermined time is determined based on the moving speed of the guide image 30 and the length of time during which the sound should be output.

  Next, after the guide image 30 reaches the second position 32a, the guide image 30 starts moving from the second position 32a toward the first position 31, as shown in FIG. 4D. As the guide image 30 moves from the second position 32a toward the first position 31, the area 33 sandwiched between the first position 31 and the guide image 30 decreases, and the second position 32a The area 34 sandwiched between the guide images 30 increases. While the guide image 30 moves away from the second position 32a and moves to the first position 31, continuation of the touch with the touch pen 22 or the like is prompted. While the touch is continued, a sound corresponding to the white key 23a being touched is output.

  Then, as shown in FIG. 4E, when the guide image 30 reaches the first position 31, that is, the color of the region 33 sandwiched between the first position 31 and the guide image 30 becomes the original state. The time point is the timing at which the user should cancel the touch operation. When the user cancels the touch operation, the sound output is stopped.

  The time for the user to perform the touch is from the time when the guide image 30 reaches the second position 32a to the time when the guide image 30 leaves the second position 32a and reaches the first position 31. The time for the user to perform touching, that is, the time for outputting the sound differs depending on the type of note (for example, quarter note, whole note). Since the guide image 30 typically moves at a constant speed, the time during which the voice is to be output can be changed by adjusting the time during which the guide image 30 stays at the second position 32a. Thereby, a plurality of musical notes can be expressed.

  For example, when expressing a whole note, the guide image 30 stays at the second position 32a for 4 seconds, and when expressing a quarter note, the guide image 30 stays at the second position 32a for 0 second. As described above, the time during which the guide image 30 remains at the second position 32a is determined based on the type of note (that is, the length of time during which the sound is to be output).

  A game progresses by repeating the movement process of the guidance image 30 mentioned above.

  FIG. 5 is a diagram illustrating a configuration of the game device according to the present embodiment. Hereinafter, a description will be given with reference to FIG. The game apparatus 300 includes a display unit 301, a detection unit 302, a determination unit 303, an output unit 304, a storage unit 305, and the like, as shown in FIG.

  As shown in FIGS. 3A, 3B, and 4A to 4E, the display unit 301 displays a keyboard 23, displays a guide image 30 on the keyboard 23, and a moving image in which the guide image 30 moves. Is displayed. The display unit 301 moves the guide image 30 from the first position 31 to the second positions 32a and 32b at a predetermined speed, and then moves from the second position 32a and 32b to the first position 31. A moving image in which the guide image 30 moves at a speed of is displayed on the screen.

The speed at which the guide image 30 moves is typically equal, and the speed at which the guide image 30 moves from the first position 31 to the second positions 32a and 32b and from the second positions 32a and 32b. The speed of moving to the first position 31 is equal.
Note that the speed at which the first position 31 moves to the second position 32a, 32b and the speed at which the second position 32a, 32b moves to the first position 31 may be different. Further, the speed may be varied during the movement from the first position 31 to the second positions 32a and 32b and from the second position 32a and 32b to the first position 31.

  In addition, the display unit 301 is configured such that the color of the region 33 sandwiched between the first position 31 and the guide image 30 is different from the color of the region 34 sandwiched between the second positions 32a and 32b and the guide image 30. To display. The areas 33 and 34 are displayed in an arbitrary color.

  The CPU core 10a, the image processing unit 10b, the VRAM 10c, the LDC controller 10e, the first / second display units 19 and 20 and the like operate in cooperation to function as the display unit 301.

  The detection unit 302 detects the state of the operating body that is in one of the first state and the second state by a user operation.

Here, the operation body refers to a device for accepting an input operation from a user, and corresponds to, for example, a touch panel, a controller, a keyboard, a mouse, and the like.
The first state refers to a state where no input operation is performed by the user or a state where the user is not performing a specified input operation. The second state refers to a state in which an input operation designated by the user is being performed.

  For example, as shown in FIG. 2 and the like, when the operating body is the touch panel 21, a state in which the user does not touch the touch panel 21 with the touch pen 22 or the like, or a predetermined key on the keyboard 23 displayed on the touch panel 21 The state in which is not touched is the first state. The state in which the user is touching a predetermined key (specifically, the key on which the guide image 30 is displayed) of the keyboard 23 with the touch pen 22 or the like is the second state.

  The CPU core 10a, the touch panel 21, the touch panel controller 10f, the operation keys 18 and the like operate in cooperation to function as the detection unit 302.

The determination unit 303 indicates that the detected state of the operating tool is
(A) While the guide image 30 moves from the first position 31 to the second position 32a, 32b, it is in the first state,
(B) While the guide image 30 moves from the second position 32a, 32b to the first position 31, it is in the second state,
(C) When the guidance image 30 reaches the first position 31 and shifts from the second state to the first state, it is determined that the user's operation is successful.

  The determination unit 303 determines whether the user's operation is successful based on the position of the guide image 30 and the state of the operation tool. For example, as shown in FIG. 4C, when the guide image 30 reaches the second position 32a, that is, when the colors of all the regions 33 sandwiched between the first position 31 and the guide image 30 change, This is the timing at which the user should perform a touch operation. At this timing, when the user touches the key on which the guide image 30 whose color has changed, specifically, the white key 23a corresponding to “F” in the figure, the user's operation is determined to be successful. The

  Further, as shown in FIG. 4E, when the guide image 30 reaches the first position 31, that is, the color of the region 33 sandwiched between the first position 31 and the guide image 30 becomes the original state. The time point is the timing when the user should cancel the touch operation. At this timing, when the user stops touching the key whose color is displayed in the original state, specifically, the white key 23a corresponding to “F” in FIG. Judged as successful.

  The CPU core 10a, the second display unit 20, the touch panel 21, the touch panel controller 10f, and the like operate in cooperation to function as the determination unit 303.

  The output unit 304 outputs a predetermined sound while the detected state of the operating tool is in the second state. The output unit 304 outputs sound corresponding to the touched key when the user touches the touch panel 21 using the touch pen 22 or the like, and stops outputting sound when the touch is released.

  The CPU core 10a, the sound amplifier 15, the speaker 16, and the like operate in cooperation to function as the output unit 304.

  The storage unit 305 stores, for example, a game progress state such as a key touched by a user, success or failure of a user operation, and a difference between a time point when the operation is performed and a time point when the operation is to be performed.

  The CPU core 10a, the RAM 12b, and the like operate in cooperation to function as the storage unit 305.

  Next, processing executed in the game device 300 of the present embodiment will be described. FIG. 6 is a flowchart showing the flow of the game process. Hereinafter, a description will be given with reference to FIG.

  Typically, the white key 23a or the black key 23b on the keyboard 23 on which the guide image 30 is displayed is determined in advance by the music or the music part. Here, for ease of explanation, a case where the guide image 30 is displayed on the white key 23 a corresponding to the “F” range of the keyboard 23 will be described.

  First, when the game apparatus 300 is turned on and the game is started by the user, the CPU core 10a displays the keyboard 23 used in the game on the second display unit 20, as shown in FIG. 4A. (Step S101). In addition, the CPU core 10a reproduces a predetermined music and outputs the music from the speaker 16.

  Note that the range (sound range) of the keyboard 23 to be displayed is arbitrary. For example, a keyboard to which a sound range such as 1 octave or 3 octaves is output is displayed.

  Next, the CPU core 10a displays the guide image 30 at the first position 31 so as to synchronize with the rhythm or the like of the music to be played back. As shown in FIG. 4B, the guide image 30 is within the white key 23a. Are displayed so as to move from the first position 31 to the second position 32a (step S102).

  FIG. 7 is a diagram showing the relationship between the speed change of the guide image 30 and the keyboard display. As shown in the figure, the CPU core 10a moves the guide image 30 at a predetermined speed (in this case, + V), and moves the guide image 30 to move the first position 31 and the guide image 30. A region 33 sandwiched between and is displayed with a predetermined color.

  When the region 33 sandwiched between the first position 31 and the guide image 30 is displayed with a predetermined color, the region 33 sandwiched between the first position 31 and the guide image 30, A region 34 sandwiched between the second positions 32a is clearly distinguished. Thereby, since the position of the guidance image 30 is easily visually recognized, the timing for performing the operation can be easily presented to the user.

  Next, the CPU core 10a detects a touch operation (step S103). Then, the CPU core 10a outputs a sound corresponding to the touch operation while the touch operation is detected. For example, as shown in FIG. 4C, when a touch on the white key 23a corresponding to “Fa” is detected, a “Fa” sound is output. While the touch operation is continued, the sound corresponding to the key that is being touched is output, and when the touch operation is released, the output of the sound is stopped.

  Next, the CPU core 10a determines whether or not the guide image 30 being moved and displayed has reached the second position 32a (step S104). The timing at which the guide image 30 reaches the second position 32a, that is, the timing at which the entire color of the white key 23a changes is the timing at which the user should perform the operation. As shown in FIG. 4C, the user is required to start touching the white key 23a whose color has changed.

  When the guide image 30 has not reached the second position 32a (step S104; No), the CPU core 10a continues the display for moving the guide image 30 (step S102).

  On the other hand, when the guide image 30 has reached the second position 32a (step S104; Yes), the CPU core 10a displays the guide image 30 at the second position 32a for a predetermined time (step S105). As shown in FIG. 7, the CPU core 10a sets the moving speed V of the guide image 30 to V = 0, stops the movement of the guide image 30, and keeps the guide image 30 at the second position 32a for display. .

  Next, the CPU core 10a determines whether or not a touch operation has been performed at the timing when the guide image 30 reaches the second position 32a (step S106). The CPU core 10a makes a determination by detecting whether or not the area on the touch screen where the white key 23a with the guide image 30 is displayed is touched.

  When the touch operation is performed at the timing when the guide image 30 reaches the second position 32a (step S106; Yes), the CPU core 10a determines that the touch operation by the user is successful and indicates success. Display (for example, “Good”, “OK”, “◯ (maru)”) is output (step S107). When a touch operation is performed, sound corresponding to the touched key is output from the speaker 16.

  Even when the touch operation is performed at the timing when the guide image 30 reaches the second position 32a, when the keyboard 23 on which the guide image 30 is not displayed is touched, the CPU core 10a It is determined that the touch operation by the user has failed. For example, as shown in FIG. 4C, a keyboard 23 other than the white key 23a corresponding to the “F” range of the keyboard 23 (for example, the white key 23a corresponding to the “M” or “SO” range) is touched. If there is, the CPU core 10a determines that the touch operation by the user has failed.

  On the other hand, when the touch operation is not performed at the timing when the guide image 30 reaches the second position 32a (step S106; No), the CPU core 10a determines that the touch operation by the user has failed, and the failure is determined. A display to the effect of the display (for example, “Bad”, “NG”, “× (bad)”, etc.) is output (step S108).

  The display contents indicating success and failure are arbitrary, and the position and size of the output display are also arbitrary. In addition, a message indicating success or failure can be output by voice or vibration.

  Next, the CPU core 10a determines whether or not to move the guide image 30 from the second position 32a to the first position 31 (step S109). For example, the CPU core 10a performs the determination based on whether or not a predetermined time has elapsed after the guide image 30 reaches the second position 32a.

The stop time T1 (s) when the guide image 30 stops at the second position 32a, the time T2 (s) when the voice should be output, the length L (cm) of the white key 23a, and the moving speed V (cm of the guide image 30) / S), the time T1 is obtained from the following equation (1).
T1 = T2- (L / V) (1)

  The CPU core 10a calculates the time T2 from the speed of the music, the type of note, and the like, and further calculates the time T1 based on the equation (1). Then, after the guide image 30 reaches the second position 32a, the CPU core 10a displays the guide image 30 so as to remain at the second position 32a until the time T1 elapses.

  8A and 8B are diagrams illustrating the relationship between the stop time of the guide image 30 and the type of note. For example, when the note type is a whole note, a time T2 for outputting a sound having the length of the whole note is determined. As shown in FIG. 8A, time T2 is the time from the start of touch to the release of touch. The time T1 is calculated based on the equation (1) so that the time T2 is a sound having the length of all notes. When the guide image 30 reaches the second position 32a, that is, until the time T1 elapses from the time when V = 0, the guide image 30 remains at the second position 32a. Thereby, the time from the time when the guide image 30 reaches the second position 32a, that is, the time when the touch starts, to the time when the guide image 30 reaches the first position 31, that is, the time when the touch is released. As a result, a note having the length of a full note is output.

  Further, for example, when the note type is an eighth note, a time T2 in which a sound having an eighth note length is output is determined. As shown in FIG. 8B, the time T2 is the time from the start of touch until the touch is released, and the time T1 is calculated based on the equation (1) so that the time T2 is a sound of an eighth note length. Calculated. In the case of this figure, T1 = 0, and when the guide image 30 reaches the second position 32a, it moves toward the first position 31 without staying at the second position 32a.

  Since the time T2 changes based on the speed of music, T1 = 0 does not necessarily occur when the note type is an eighth note. The time T1 can be arbitrarily changed based on the speed of the music, the moving speed of the guide image 30, the type of the note, and the like.

  When the guide image 30 is not moved to the first position 31, that is, when the guide image 30 is kept at the second position 32a (step S109; No), the CPU core 10a, as shown in FIG. Is continuously displayed at the second position 32a (step S105), and then it is determined again whether or not the guide image 30 is to be moved (step S109).

  When it is determined No in Step 109 and Steps S105 to S108 are repeated, the CPU core 10a can omit the processes of Steps S107 and S108.

  On the other hand, when the guide image 30 is moved to the first position 31 (step S109; Yes), the CPU core 10a causes the guide image 30 to move to the second position along the white key 23a as shown in FIG. 4D. The display is performed so as to move from 32a to the first position 31 (step S110). As shown in FIG. 7, the CPU core 10 a moves the guide image 30 at a moving speed of −V. As the guide image 30 moves, the area 33 sandwiched between the first position 31 and the guide image 30 is reduced.

  Next, the CPU core 10a determines whether or not the guide image 30 that is being moved and reached has reached the first position 31 (step S111). The timing at which the guide image 30 reaches the first position 31, that is, the timing at which the entire color of the white key 23a returns to the original color is the timing at which the touch should be released.

  At the touch start timing, the guide image 30 is displayed at the second position 32a. On the other hand, at the touch release timing, the guide image 30 is displayed at the first position 31 that is a predetermined distance away from the second position 32a. This is because the touch image is not blocked by the touch pen 22 or the user's finger because the touch has not yet been made at the touch start timing. However, while the touch is made and the touch is continued, the display of the guide image 30 may be blocked by the touch pen 22 or the like. Therefore, the display of the guide image 30 is blocked by the touch pen 22 or the like by using the first position 31 that is a predetermined distance away from the second position 32a indicating the touch start timing as the touch release timing. The timing for performing the operation can be presented to the user.

  Also, the user can be presented with two timings of touch start and touch release simply by displaying on the screen a moving image of the guide image 30 that moves between two positions separated by a predetermined distance. For this reason, even if it is a screen with a limited display range, it is possible to present a timing for performing an operation to the user.

  When the guide image 30 has not reached the first position 31 (step S111; No), the CPU core 10a continues the display for moving the guide image 30 (step S110).

  On the other hand, when the guide image 30 reaches the first position 31 (step S111; Yes), the CPU core 10a determines whether or not the touch is released at the timing when the guide image 30 reaches the first position 31. Is determined (step S112). The CPU core 10a makes a determination by detecting whether or not the area on the touch screen where the white key 23a with the guide image 30 is displayed is not touched.

  When the touch operation is released at the timing when the guide image 30 reaches the first position 31 (step S112; Yes), the CPU core 10a determines that the release of the touch operation by the user is successful and succeeds. Is displayed (step S113). When the touch operation is released, the output of the sound corresponding to the touched key is stopped.

  On the other hand, when the touch operation is not released at the timing when the guide image 30 reaches the first position 31 (step S112; No), the CPU core 10a determines that the release of the touch operation by the user has failed. Then, a display indicating failure is output (step S114). While the touch operation is continued, a sound corresponding to the key being touched is output.

  Then, the CPU core 10a returns to the process of step S101 and repeats the processes of steps S101 to S114.

  Through the above processing, the timing at which the user should perform the operation can be presented.

(Embodiment 2)
In the first embodiment, the guide image 30 is described as an image formed in a linear shape corresponding to the lower side of the belt-like image 30a as shown in FIG. 3B. In the present embodiment, the guide image 30 is described as a belt-like image having a length from the first position 31 to the second position 32a. In addition, about the structure which is common in the above-mentioned embodiment, description is abbreviate | omitted using the same reference number.

  9A to 9D are diagrams for explaining the movement of the guide image 30 according to the second embodiment. As shown in FIG. 9A, the guide image 30 appears from the first position 31 and moves toward the second position 32a while gradually changing the position as time elapses. In the area 35 where the guide image 30 and the white key 23a overlap, the guide image 30 is displayed on the screen so as to be in front of the white key 23a. On the other hand, in the area 36 where the guide image 30 and the white key 23a do not overlap, the guide image 30 is not displayed on the screen. As the guide image 30 moves from the first position 31 to the second position 32a, the area 35 gradually increases and the area 36 gradually decreases.

  Next, as shown in FIG. 9B, when the guide image 30 reaches the second position 32a, that is, when the guide image 30 and the white key 23a are displayed so as to be completely overlapped, the user performs a touch operation. It is time to do it.

  Next, after the guide image 30 reaches the second position 32a, as shown in FIG. 9C, the guide image 30 moves while gradually changing the position. As the guide image 30 moves from the second position 32a to the first position 31, the area 35 gradually decreases and the area 36 gradually increases.

  Then, as shown in FIG. 9D, the time when the area 35 where the guide image 30 and the white key 23a overlap disappears is the timing at which the user should release the touch operation. The user starts touching when the guide image 30 and the white key 23a are displayed so as to be completely overlapped, and performs the touch operation while the area 35 where the guide image 30 and the white key 23a overlap is displayed. By continuing and then releasing the touch operation when the area 35 disappears, it is determined that the user's operation is successful.

  A game progresses by repeating the movement process of the guidance image 30 mentioned above.

  The guide image 30 is typically displayed with a color different from the color of the white key 23a. For this reason, since the color of the image showing the region 35 where the guide image 30 and the white key 23a overlap each other and the color of the white key 23a are displayed in different colors, the user clearly defines the position of the guide image 30. Can grasp. Further, the timing for performing the touch operation and the timing for releasing the touch operation are presented to the user according to the position where the guide image 30 has moved. For this reason, the user can grasp | ascertain the timing which should be operated easily by visually recognizing the position of the guidance image 30. FIG.

  Further, the guide image 30 displayed between the first position 31 and the second position 32a is displayed so that the position gradually changes as time passes. Since the range in which the guide image 30 is displayed is limited between the first position 31 and the second position 32a, the movement of the user's line of sight can be reduced.

  As described above, according to the present embodiment, it is possible to present the timing at which the user should perform an operation. Further, the movement of the user's line of sight can be reduced.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation and application are possible.

  In the process in which the guide image 30 moves from the first position 31 to the second position 32a and then moves from the second position 32a to the first position 31, the moving speed of the guide image 30 changes midway. It can also be made. FIG. 10 is a diagram illustrating an example in which the moving speed of the guide image 30 changes in the middle. In this figure, when moving from the first position 31 to the second position 32a, the guide image 30 moves at a moving speed of + V1, and when moving from the second position 32a to the first position 31, It is moving at the moving speed of V2. If the area S1 and the area S2 shown in the figure are equal, the distance the guide image 30 has moved becomes equal. When the distance traveled by the guide image 30 matches the length L of the keyboard, the guide image 30 has moved between the first position 31 and the second position 32a. That is, as long as S1 = S2 = L is satisfied, the guide image 30 can be moved at an arbitrary moving speed.

  While the present invention is typically applied to instruments that output sound without attenuation while the key is held down, string instruments (eg, guitars, violins), brass instruments (eg, trumpet) , Saxophone), percussion instruments (eg, drums, tambourine), etc.

The present invention can be applied to any method that presents a user with two timings: a timing to start a touch and a timing to release the touch. For example, in the so-called step up / down of the platform that climbs on or off the platform, the timing for placing the foot on the platform is the timing for starting the touch, and the timing for lowering the foot from the platform is the timing for releasing the touch. It is also possible to correspond to each. In this case, the time during which the foot is kept on the stand corresponds to the time during which the touch is continued.
Also, in a so-called flag raising game in which a flag is raised or lowered based on an instruction to raise or lower the flag, the timing for raising the flag is equivalent to the timing for starting the touch, and the timing for raising the flag is equivalent to the timing for releasing the touch. You can also. In this case, the period during which the flag is raised corresponds to the period during which the touch is continued.

  As described above, according to the present invention, it is possible to provide a game device, a game control method, and a program that realizes these on a computer that are suitable for presenting the timing at which the user should perform an operation.
