For example, a smartphone equipped with a touch panel 40 can be used as the game machine 3.

  The game machine 3 receives the game program 1 from the wireless communication unit 38 or the media interface 39 and stores it in the storage 34. The CPU 31 reads out and executes the game program 1 stored in the storage 34 on the RAM 32, and configures a game device to be described later using the above hardware resources. The game program 1 can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or can be provided through a network.

<About the game>
Next, a game provided by the game program in the present embodiment will be described.

  This game is a timing game in which the player's operation is evaluated at the timing when the tips of a plurality of lines appearing from the end of the game screen collide with each other.

  FIG. 2 shows an example of the game screen. Lines 51A and 51B and predictive images 52A to 52C are displayed on the game screen shown in FIG. Information such as a score is also displayed on the actual game screen, but it is not shown here. Moreover, you may display the promotion video according to the music reproduced | regenerated as a background of a game screen.

  The lines 51A and 51B appear and extend from the end of the game screen in accordance with the music output from the game machine 3, and the ends collide at a virtual intersection 53 in the game screen. The virtual intersection 53 is not displayed on the game screen.

  The sign images 52A to 52C are images showing signs that the ends of the lines 51A and 51B are close to each other, and are displayed on the game screen before the lines 51A and 51B appear or simultaneously with the appearance of the lines 51A and 51B. The rough collision timing of the lines 51A and 51B and the position of the virtual intersection 53 are shown to the player. In the example illustrated in FIG. 2, as the indication images 52A to 52C, images in which the traveling directions of the lines 51A and 51B are represented by a plurality of broken lines are used, and the position of the virtual intersection 53 is determined in the traveling direction of the folding points of the indication images 52A to 52C. The collision timing of the lines 51A and 51B is shown by the change in the interval between the predictive images 52A to 52C.

  Here, the movement of the lines 51A and 51B and the precursor images 52A to 52C will be described. FIG. 3 is a diagram showing, in chronological order, how the lines 51A and 51B appear in the game screen and approach the virtual intersection 53. FIG.

  As shown in FIGS. 3A to 3C, the lines 51A and 51B appear from the left side of the upper and lower ends of the game screen and extend toward the virtual intersection 53 near the center of the game screen. That is, the line 51A extends in the lower right direction, and the line 51B extends in the upper right direction.

  The sign image 52A appears from the left side of the game screen slightly before the appearance of the lines 51A and 51B and moves to the right side. Another predictor image 52B appears from the left side of the game screen and moves to the right following the predictor image 52A simultaneously with the appearance of the lines 51A and 51B. Further, another sign image 52C appears from the left side of the game screen and moves to the right after the sign images 52A and 52B after the appearance of the lines 51A and 51B.

  The moving speed of each of the predictor images 52A to 52C increases as the appearance speed decreases. Therefore, as shown in FIGS. 3A to 3C, the interval between the predictor images 52A to 52C becomes narrower as the lines 51A and 51B approach the virtual intersection 53, and the predictor images 52A to 52C As the time elapses, the lines 51A and 51B overlap each other at the virtual intersection 53 as the ripples approach the virtual intersection 53. At this time, the break points of the predictor images 52 </ b> A to 52 </ b> C overlap at the virtual intersection 53.

  The player can estimate the rough timing at which the tips of the lines 51A and 51B collide and the position of the virtual intersection 53 by observing the predictive images 52A to 52C.

<Game device>
Next, a game apparatus configured by reading the game program in the present embodiment into the game machine 3 will be described.

  FIG. 4 is a functional block diagram showing a configuration of a game device constituted by the game program in the present embodiment. The game device shown in the figure includes an operation input unit 11, a predictive image control unit 12, a line control unit 13, a timing determination unit 14, a score processing unit 15, an image output unit 16, a background processing unit 17, a voice output unit 18, and A game data storage unit 19 is provided.

  The operation input unit 11 inputs a player's operation. The player inputs an operation by touching the touch panel 40 of the game machine 3 with a finger or the like. There are taps, flicks, long presses, swipes, and so on. The operation input unit 11 acquires operation information such as contact coordinates on the game screen and the type of operation, and transmits the operation information to the timing determination unit 14.

  The sign image control unit 12 causes the sign images 52A to 52C corresponding to the lines 51A and 51B to appear on the game screen, controls the movement of the sign images 52A to 52C, and displays the position information of the sign images 52A to 52C. It transmits to the image output part 16, and the sign image 52A-52C on a game screen is updated. The appearance timing of the predictive images 52A to 52C, the motion data, and the like are read from the game data storage unit 19.

  The line control unit 13 causes the lines 51A and 51B to appear on the game screen according to the music output from the audio output unit 18, and controls the movement so that the ends of the lines 51A and 51B collide with each other. , 51B is transmitted to the image output unit 16 to update the lines 51A, 51B on the game screen. In addition, timing determination is performed on proximity information such as the position information of the virtual intersection 53 that is the position where the tips of the lines 51A and 51B collide, the position information of the lines 51A and 51B, and the time until the tips of the lines 51A and 51B collide. To the unit 14. The appearance timing of the lines 51A and 51B, the speed of extension, and the like are read from the game data storage unit 19.

  The timing determination unit 14 receives the operation information from the operation input unit 11, and also receives the proximity information of the tips of the lines 51A and 51B from the line control unit 13, and determines whether or not an appropriate position is tapped at an appropriate timing. The determination is made and the success or failure of the tap is transmitted to the score processing unit 15.

  The score processing unit 15 performs score addition processing based on the success or failure of the tap received from the timing determination unit 14. Further, the score processing unit 15 transmits a value of a parameter such as a score to the image output unit 16 and updates the value displayed on the game screen.

  The image output unit 16 receives the position information of the lines 51A and 51B from the line control unit 13 and displays the lines 51A and 51B on the game screen, and also receives the position information of the sign images 52A to 52C from the sign image control unit 12. Then, the predictive images 52A to 52C are displayed on the game screen. In addition, parameter values such as scores and background images are displayed on the game screen.

  The background processing unit 17 reads the background image to be displayed behind the lines 51A and 51B and the predictive images 52A to 52C from the game data storage unit 19 and causes the image output unit 16 to display the background image.

  The audio output unit 18 acquires music data from the game data storage unit 19 and outputs it.

  The game data storage unit 19 stores image data to be displayed on the game screen, audio data such as music and sound effects to be reproduced, line appearance data, and sign appearance data.

  The line appearance data includes information such as the position of the virtual intersection, the number of appearance, the appearance timing of the line, the appearance position, the extending direction / speed, and the like. The position of the virtual intersection represents coordinates on the game screen. The number of appearances represents the number of lines that intersect at a virtual intersection. The appearance timing is data that describes, for each line, how long a time has elapsed since the start of music playback. The appearance position is, for example, data describing coordinates for each line when any corner of the game screen is set as the origin. The extending direction / speed is data describing the extending direction and speed for each line. The speed at which the line extends may vary from line to line.

  The sign appearance data is associated with the line appearance data and includes information such as the appearance timing, appearance position, movement speed, and change information of the sign image. The appearance timing is data describing how much time has elapsed since the start of music reproduction, or the relative time from the appearance timing of the line to the appearance timing of the predictive image. The appearance position is data describing the position where the sign image appears. The moving speed is data describing the moving speed of the precursor image. The change information is data describing how to change, for example, when the color of the predictor image is changed.

<Process flow>
Next, a processing flow of the game device will be described.

  FIG. 5 is a flowchart showing an overall processing flow of the game apparatus.

  When the game is started, an initialization process is performed (step S11). The initialization process includes, for example, initialization of parameters such as clearing of a score, selection of line appearance data to be used with music to be reproduced, and sign appearance data. The music selected by the player and the music set in advance according to the difficulty level are selected as the music to be played.

  When the initialization process is completed, the audio output unit 18 starts playing music (step S12).

  The line control unit 13 reads the line appearance data from the game data storage unit 19 and determines whether or not new lines 51A and 51B appear (step S13). Whether or not new lines 51A and 51B appear is determined by, for example, comparing the music playback time with the appearance timing of the line appearance data. When the music playback time is equal to or greater than the appearance timing, it is determined that new lines 51A and 51B appear.

  When it is determined that new lines 51A and 51B are to appear, the predictor images 52A to 52C and the lines 51A and 51B are caused to appear on the game screen (step S14). The line control unit 13 causes the lines 51A and 51B to appear at the appearance positions of the line appearance data read from the game data storage unit 19, and the sign image control unit 12 applies the lines 51A and 51B that the line control unit 13 causes to appear. Corresponding sign appearance data is read from the game data storage unit 19, and the sign images 52A to 52C appear on the game screen. The sign images 52A to 52C may appear on the game screen before the appearance of the lines 51A and 51B. In this case, the appearance positions of the lines 51A and 51B are set outside the game screen.

  At predetermined intervals, the line control unit 13 moves the lines 51A and 51B on the game screen (step S15), and the sign image control unit 12 updates the sign images 52A to 52C (step S16). The lines 51A and 51B and the predictive images 52A to 52C displayed on the game screen are moved and updated at predetermined intervals (for example, 60 fps intervals).

  Then, the timing determination unit 14 determines whether or not the player has tapped the virtual intersection 53 where the ends of the lines 51A and 51B collide with each other at an appropriate position and timing (step S17). Details of this determination processing will be described later.

  Further, it is determined whether or not a game end condition is satisfied (step S18). As for the game end condition, for example, it is determined that the game is cleared when the reproduction of the music is ended, and it is determined that the game is over when the number of times determined to be a mistake in the determination process exceeds a predetermined value. If the game end condition is not satisfied, the process returns to step S13 to continue the game.

  If the game end condition is satisfied, a message indicating that the game is cleared or the game is over is displayed on the game screen, and the game is ended (step S19). After the game ends, if the game is cleared, the process returns to step S11 to start a new game, and if the game is over, the process returns to the title.

  Next, the determination process will be described. In the determination process, it is determined whether or not the collision location on the game screen has been tapped at the timing at which the ends of the lines collide.

  FIG. 6 is a flowchart showing the flow of the determination process.

  First, it is determined whether or not the game screen has been tapped (step S21).

  When the game screen is tapped (Yes in step S21), the tap coordinates on the game screen are acquired (step S22), and it is determined whether or not the tap position is within an appropriate range (step S23). Whether or not the tap position is within the appropriate range is determined by comparing the tap coordinates and the virtual intersection 53 indicating the position where the tips of the lines collide with each other.

  When the tap coordinates are within a predetermined range from the virtual intersection 53 (Yes in Step S23), it is determined whether or not the tap timing is within an appropriate range (Step S24). Whether or not the tap timing is within the appropriate range is determined by obtaining a deviation from the just timing of the tap timing when the timing at which the ends of the lines 51A and 51B collide is the just timing. For example, the determination is made using proximity information describing the time until the collision.

  If the tap timing is within the appropriate range (Yes in step S24), the score is added according to the tap timing (step S25), and the tapped lines 51A and 51B are deleted from the game screen (step S26). . When tapped at the just timing, the maximum score is added. Otherwise, a smaller score is added.

  On the other hand, if the game screen is not tapped (No in step S21), or if the tap position is outside the appropriate range (No in step S23), it is determined whether the timing at which the virtual intersection 53 should be tapped has been missed (step S21). S27). If a predetermined time has elapsed after the leading ends of the lines 51A and 51B collide, it is determined that the tap timing has been missed.

  If the tap timing has been missed (Yes in step S27), the collision position of the lines 51A and 51B could not be tapped at an appropriate timing. (Step S28), the lines 51A and 51B that could not be tapped are deleted from the game screen (Step S26).

<Variation>
Next, variations of lines and predictive images will be described.

  FIG. 7 is a diagram showing variations of lines and predictive images. Hereinafter, each variation shown in FIG. 7 will be described.

  FIG. 7A is a diagram illustrating an example in which a plurality of sets of lines appear simultaneously. In the example shown in FIG. 7A, a plurality of sets of lines 51A to 51D that collide at different virtual intersections 53A and 53B respectively appear on the game screen at the same time. In the example shown in FIG. 7A, the player taps in the order of the virtual intersections 53A and 53B. In the example shown in FIG. 7A, the lines 51A to 51D extend at the same angle with respect to the sides of the game screen, but may extend at different angles with respect to the sides of the game screen. For example, the line 51A extends at an angle of 45 degrees with respect to the upper side of the game screen, and the line 51B extends at an angle of 90 degrees with respect to the lower side of the game screen. Moreover, the speed at which each of the lines 51A to 51D extends may be the same or different. For example, it is possible to make the tap timing difficult by increasing the speed at which the line 51A extends and decreasing the speed at which the line 51B extends. The speed may appear at a constant speed, or the speed may change at a predetermined timing after the appearance. For example, the speed may change after the line disappears for a moment.

  FIG. 7B is a diagram illustrating an example in which the lines 51A and 51B disappear or appear. In the example shown in FIG. 7B, when the lines 51A and 51B extend, the lines 51A and 51B are temporarily hidden. Alternatively, a part of the lines 51A and 51B is not displayed. When the lines 51A and 51B are not displayed, the sign image may be not displayed or only the sign image may be displayed.

  FIG. 7C is a diagram illustrating an example in which a line collision is predicted by a color change. In the example shown in the figure, a predictive image 52 (pentagon in FIG. 7C) in which the color changes is arranged at a portion delimited by the lines 51A and 51B when the lines 51A and 51B collide. The sign image 52 changes color according to the growth of the lines 51A and 51B. For example, the color of the predictive image 52 is black or transparent so that it is not distinguished from other parts when it appears, and gradually becomes red or decreases in transparency. The player can know the rough timing when the lines 51A and 51B collide with each other based on the color density and transparency of the sign image 52, and can know the direction in which the lines 51A and 51B extend and the position of the virtual intersection 53 based on the shape of the sign image 52. it can.

  FIG. 7D is a diagram illustrating an example in which a line collision is predicted by a change in line thickness. In the example shown in the figure, the thick line including the lines 51 </ b> A and 51 </ b> B and the virtual intersection 53 is used as the sign image 52. The predictor image 52 becomes thinner as the lines 51A and 51B approach. The player knows the rough timing at which the lines 51A and 51B collide with the change in the thickness of the predictor image 52, and knows the direction in which the lines 51A and 51B extend and the rough position of the virtual intersection 53 at the position of the predictor image 52. it can.

  FIG. 8 is a diagram illustrating an example in which four lines collide. As shown in FIG. 8, the number of colliding lines may be larger than 2, and for example, four lines 51 </ b> A to 51 </ b> D may collide at one virtual intersection 53. When the four lines 51 </ b> A to 51 </ b> D collide, the player's operation may be performed by flicking (flicking with a finger) or long pressing (holding for a while) instead of tapping. Furthermore, as shown in FIG. 8B, when the four lines 51A to 51D collide at one virtual intersection 53, when the player presses the collision position, the sphere 54 is placed at the position pressed by the player. A hole 55 appears at an arbitrary position on the game screen. Then, the ball 54 is moved by the player's flick operation, and when the ball 54 enters the hole 55, the score is added. The sphere 54 may be rebounded on the side of the game screen, or the sphere 54 may be directly placed in the hole 55. The movement of the sphere 54 is determined based on the timing, angle, speed, length, etc. of the flick by the player. The flick length is the distance from the start point to the end point of the touched position.

  Further, various operations such as tap, flick, and long press may be requested according to other attributes (eg, thickness, color, display method, etc.) of the lines 51A and 51B as well as the number of lines that collide. .

<Movement in the depth direction of the line>
In the embodiments described so far, the line moves only in the direction in which the line extends, and does not move in any direction other than the direction in which the line extends. Here, an embodiment will be described in which a line is moved in a direction other than the direction in which the line extends to make the line appear to move in the depth direction.

  FIG. 9 is a diagram showing the game screen with the line display position moved in chronological order in the order of (a) to (c). In the embodiment shown in FIG. 9, the lines 51A and 51B and the predictive images 52A and 52B are displayed on a background with a sense of depth using perspective, and the lines 51A and 51B move from the back to the front (depth direction). As shown, the display positions of the lines 51A and 51B are moved.

  As the background of the game screen, the floor 58A and the ceiling 58B are expressed by lines radiating from the vanishing point 56 set at the center of the game screen, giving a sense of depth. Level meters 58C indicating the volume of music to be reproduced are arranged on both sides of the floor 58A. The display positions on the game screen of the floor 58A, the ceiling 58B, and the level meter 58C are moved toward each other for each frame, and the player feels that the player is moving toward the vanishing point 56. Specifically, the horizontal line of the floor 58A is moved downward, the horizontal line of the ceiling 58B is moved upward, and the left and right level meters 58C are moved downward in the horizontal direction so as to be away from the vanishing point 56 on the game screen. The moving speed of the background images such as the floor 58A, the ceiling 58B, and the level meter 58C is adjusted to the tempo (BPM) of the music to be reproduced. The floor 58A, the ceiling 58B, and the level meter 58C are backgrounds for giving a sense of depth and speed, and are not related to the operation of the player. By moving and displaying the floor 58A, the ceiling 58B, and the level meter 58C away from the vanishing point 56, the background is displayed so as to move in the depth direction, thereby creating a sense of speed.

  The lines 51 </ b> A and 51 </ b> B are displayed so as to overlap the background with a sense of depth, and are moved so that the display positions of the lines 51 </ b> A and 51 </ b> B are separated from the vanishing point 56. Specifically, as shown in FIGS. 9A to 9C, the laterally extending line 51 </ b> A displayed above the vanishing point 56 on the game screen is moved upward in accordance with the elapsed time. The line 51B extending in the vertical direction displayed to the right of the vanishing point 56 is moved to the right according to the elapsed time. The size (thickness) of the lines 51A and 51B is also increased (thickened) according to the elapsed time.

  The predictive images 52A and 52B are displayed so as to indicate the virtual intersection 53 that extends the lines 51A and 51B at the current display position, not the expected collision position 57 that is the final collision position of the lines 51A and 51B. . In the example shown in FIG. 9, strip-shaped sign images 52A and 52B extending in the longitudinal direction of the lines 51A and 51B are displayed. The intersection of the two strip-shaped sign images 52A and 52B corresponds to the virtual intersection 53.

  Next, processing for calculating the display positions of the lines 51A and 51B and the sign images 52A and 52B will be described.

  The display positions of the lines 51A and 51B are determined based on the position of the virtual intersection 53 that moves from the vanishing point 56 to the final collision position 57 that is the final collision position with the passage of time. The position of the virtual intersection 53 is determined by interpolation on the line connecting the vanishing point 56 and the expected collision position 57 according to the elapsed time.

  FIG. 10 shows how the position of the virtual intersection 53 is moved. In the example shown in the figure, it is assumed that the virtual intersection 53 moves from the vanishing point 56 to the expected collision position 57 in one bar, the predictive images 52A and 52B are 3 beats before the just timing, and the lines 51A and 51B are 2 of the just timing. It is supposed to appear before the beat.

  When three beats before the just timing, that is, when the predictive images 52A and 52B appear, the virtual intersection 53 is located at a position P that is 3/4 from the expected collision position 57 to the vanishing point 56, as shown in FIG. And the sign images 52A and 52B are displayed with the virtual intersection 53 as a reference. Specifically, the band-like predictive images 52A and 52B are displayed from the virtual intersection 53 to the sides where the lines 51A and 51B appear.

  As time passes, the virtual intersection 53 is moved on the line segment toward the expected collision position 57, and the display positions of the predictive images 52A and 52B are corrected and moved in accordance with the position of the virtual intersection 53.

  Then, two beats before the just timing, that is, when the lines 51 </ b> A and 51 </ b> B appear, the virtual intersection 53 reaches the half position Q from the expected collision position 57 to the vanishing point 56 as shown in FIG. The sign images 52A and 52B are displayed with reference to the virtual intersection 53, and lines 51A and 51B appear with the virtual intersection 53 as a reference. Specifically, the line 51A appears at the left end of the game screen according to the vertical position of the virtual intersection 53, and the line 51B appears at the lower side of the game screen according to the horizontal position of the virtual intersection 53.

  Thereafter, the lines 51A and 51B are extended, the virtual intersection 53 is moved toward the expected collision position 57, and the display positions of the lines 51A and 51B and the predictive images 52A and 52B are corrected and moved according to the position of the virtual intersection 53. Let At the just timing, the virtual intersection 53 reaches the expected collision position 57, and the ends of the lines 51A and 51B collide with each other at the expected collision position 57. The score is added by tapping the collision position of the lines 51A and 51B on the game screen at the just timing. Compare the tapped position and the collision position on the game screen, the tapping timing and the just timing, and if the tapping position and the collision position are in the specified range, the tapping timing and the just timing are within the predetermined range. If it is out of the predetermined range, it is determined as failure.

  Note that when the moving speed of the lines 51A and 51B is increased in the game setting, for example, the appearance timing of the predictive images 52A and 52B is 2 beats before the just timing, and the appearance timing of the lines 51A and 51B is 1 beat from the just timing. Before. When the moving speed of the lines 51A and 51B is slowed, the appearance timing of the predictive images 52A and 52B is set to 4 beats before the just timing, and the appearance timing of the lines 51A and 51B is set to 3 beats before the just timing.

  Moreover, you may add the setting which does not display the precursor images 52A and 52B. When the display positions of the lines 51A and 51B move without displaying the predictive images 52A and 52B, it becomes difficult for the player to grasp the collision positions of the lines 51A and 51B, and the difficulty of the game can be increased.

<3D space>
In the above-described embodiment, the lines are superimposed on the background with a sense of depth, and the lines are moved in the depth direction by moving the display position of the lines. Here, an example in which a line object is moved in the depth direction as well as up, down, left, and right in a three-dimensional virtual space will be described.

  When line objects are arranged in a three-dimensional virtual space, a plurality of line objects are arranged on a plane that is parallel to the plane of the game screen when the perspective transformation of the three-dimensional virtual space is performed, and lines are formed on the plane. Stretch the object to make it collide. Move the line object to the depth direction (direction perpendicular to the game screen) by bringing the viewpoint (virtual camera placed in the virtual space) closer to the plane where the line is placed, or by bringing the line object closer to the viewpoint. ). At the timing when the tip of the line object collides, the user's operation on the position on the game screen corresponding to the collision position is evaluated.

  On the game screen, an image obtained by perspective-transforming a three-dimensional virtual space and projected onto a two-dimensional plane is displayed. For lines, place the line as a large object in a three-dimensional virtual space and display the line object on the game screen through perspective transformation, or project only the position of the line on the two-dimensional plane. There is a method of calculating a position on the game screen and drawing a line at the calculated position on the game screen. In the latter method, the thickness of the line is determined based on the distance in the depth direction.

  For the predictive image, a method of arranging a large object in the virtual space like the line object, or calculating the position on the game screen by projecting the collision position of the line, that is, the position of the virtual intersection on the two-dimensional plane, There is a method of displaying a predictive image based on the calculated virtual intersection on the game screen.

  Note that when the tip of the line object collides is when the distance between the viewpoint and the surface on which the line is placed becomes a constant value, the thickness of the line drawn on the game screen at the time of the collision is constant. It becomes.

<Match>
Next, an embodiment in which this game is played against other players will be described.

  First, when starting a game, it connects to a server and matches an opponent. There are, for example, a method of selecting an opponent from among players registered by himself or a method of selecting randomly from players who are close to each other.

  Then, after the play data of the matched opponent is read from the server, the game is started. In addition to information identifying the player or game device, such as the player's name and ID, the server also includes (1) play data when all players have a high score for each song and each difficulty level (so-called ghost data) (2) Play data (ghost data) of the last several hundred plays of each song and each difficulty level by all players are stored. The data of (1) is used when selecting an opponent from among the players registered by himself, and the data of (2) is used when selecting an opponent from players who are close to each other.

  During the game, the difference from the opponent's score is displayed below the player's score on the game screen. The score difference between the opponent and the opponent is obtained by determining the score of the opponent using the read play data and determining the difference in score during the game, assuming that the player and the opponent start the game at the same time.

  At the end of the game, the win / loss with the opponent is displayed. Thereafter, the player's match result is displayed numerically on the result display screen. Moreover, in order to use as play data of the last several hundred play, regardless of a score, a player's play data are transmitted to a server for every play.

  For example, the game device stores key data (operation input information) based on the player's operation input as play data, and transmits the key data to the server for storage at the end of the game. The game device of the player who performs the match reads the opponent's key data stored in the server and uses it as an operation input for the opponent, and calculates the score of the opponent as the game progresses. Note that other game devices may be connected in real time by connecting with, for example, P2P communication and transmitting / receiving key data to / from each other.

  As described above, according to the present embodiment, the background drawn in perspective is displayed so as to move in the depth direction in the timing game of tapping the position at which the tips of the lines 51A and 51B collide. In addition, by moving the lines 51A and 51B according to the background, it is possible to make the lines 51A and 51B appear to move in the depth direction, and a timing game with a sense of speed can be provided.

  According to the present embodiment, in order to make the lines 51A and 51B appear to move in the depth direction, the virtual intersection 53 to which the lines 51A and 51B are extended is moved toward the expected collision position 57. The positions of the virtual intersection 53 when the predictive images 52A and 52B and the lines 51A and 51B appear on the game screen are shifted from the planned collision positions 57 where the tips of the lines 51A and 51B actually collide, and the ends of the lines 51A and 51B It becomes difficult to predict the position and timing at which the player collides, and the interest of the player can be increased.

  According to the present embodiment, in the timing game in which a plurality of lines arranged in a three-dimensional virtual space are moved to cause the tips to collide with each other, and the position where the tip of the line collides is tapped. By moving the viewpoint for perspective-transforming a two-dimensional virtual space into a two-dimensional plane in the direction of the line, the line can be moved in the depth direction as well as the plane of the game screen.
