Abstract

An object is to realize that an object is caused to move based on the acceleration data detected by an acceleration sensor when a controller is moved and the controller is caused to vibrate by a vibration mechanism when the moved object makes contact with another object. In the present game program, velocity magnitude data of a controller and velocity magnitude data of an object are calculated based on acceleration data and time interval data, both of which are recognized by a control unit. Then, it is judged by the control unit whether or not the coordinate data within the display range of a moving bat character corresponds to the coordinate data within the display range of a ball character. Next, vibration control data for controlling vibration of the controller is calculated by the control unit depending on the velocity of the bat. Accordingly, a command for outputting the vibration control data to the controller is issued by the control unit.

    This application claims priority to Japanese Patent Application No. 2005-372072 and International Patent Application No. PCT/JP2006/321230. The entire disclosure of Japanese Patent Application No. 2005-372072 and International Patent Application No. PCT/JP2006/321230 is hereby incorporated herein by reference.
  • BACKGROUND ON INVENTION
  • [0002]
    1. Technical Field
  • [0003]
    The preset invention relates to a video game program, particularly to a video game program for causing a computer to realize a video game in which a plurality of objects are displayed on an image display unit, and an object is caused to move based on the acceleration data detected by an acceleration sensor when a controller in which the acceleration sensor and a vibration mechanism are embedded is moved, and the controller is caused to vibrate by the vibration mechanism when the moved object makes contact with another object. Also, the present invention relates to a video game device that is capable of executing the video game to be realized by the video game program, and relates to a video game control method for allowing a computer to control the video game to be realized by the video game program.
  • [0004]
    2. Background Art
  • [0005]
    Various video games have been proposed in the past. The video games are configured to be executed in a game device. For example, a general game device includes a monitor, a game console that is provided separately from the monitor, and an input unit (e.g., a controller) that is provided separately from the game console. An input part (e.g., a plurality of input buttons) is disposed on the controller. A game device of this type is configured to be capable of causing an object displayed on the monitor to perform an action by manipulating the input buttons.
  • [0006]
    A situation is hereinafter considered that a versus-type game (e.g., baseball game) is executed in a game device of this type. In the baseball game, it is possible to cause an object displayed on a monitor (e.g., a bat of a batter character) to perform an action by manipulating input buttons of a controller. JIKKYOU PAWAFURU PURO YAKYU 9 KETTEIBAN, Konami Corporation, for PS2 discloses such game, as an example. In this case, first of all, either a contact hitting cursor is set to either a powerful swing mode or a normal swing mode by pressing a contact hitting cursor selection button. Then, when up, down, right, and left portions of a cross-shaped button are pressed, the contact hitting cursor accordingly moves up, down, right, and left. Next, if an X button is pressed so that a bat is capable of hitting a ball when the ball released by a pitcher character reaches a ball passing position on a hitting surface, the batter character starts swinging the bat. Accordingly, the bat displayed on the monitor starts moving at the constant velocity. Then, if the pitched ball is capable of being hit with the bat moving on the monitor when the pitched ball reaches the hitting surface, the pitched ball is hit back with the bat. Here, the controller is configured to vibrate in a weak vibration pattern when the bat makes solid contact with the ball, and is configured to vibrate in a strong vibration pattern when the bat did not make solid contact with the ball.
  • SUMMARY OF INVENTION
  • [0007]
    In the conventional baseball game, a controller is configured to vibrate either in a vibration pattern for a condition that a bat could make solid contact with a ball or in a vibration pattern for a condition that a bat could not make solid contact with a ball. Accordingly, a game player is capable of experiencing a sense that a batter feels when he hits a ball in the real baseball by means of the controller's vibration in a simulated way. However, the sense that a batter feels when he hits a ball in the real baseball is largely influenced not only by whether or not a bat could make solid contact with a ball but also the magnitude of the swing velocity of a batter. For the purpose of allowing a game player to experience the above described sense with the controller in a simulated way, it is necessary to evaluate the swing velocity of a batter such as the moving velocity of a bat displayed on a monitor and to create the data for causing the controller to vibrate based on the evaluation. However, the conventional baseball game could not appropriately evaluate the moving velocity of a bat, that is, the swing velocity of a batter. Therefore, it has been difficult to cause a controller to vibrate depending on the swing velocity of a batter when a ball is hit with a bat.

In the vibration control data issuing function, the command for outputting the vibration control data to the controller is issued by the control unit.
  • [0021]
    When a baseball game to be realized by the game program is exemplified, a plurality of objects, such as a batter character (including a bat character) and a ball character, are displayed on the image display unit with the image data corresponding to each of the characters. Also, the acceleration data to be continuously inputted into the input unit from the controller is recognized by the control unit. Then, a time interval of the acceleration data to be continuously inputted into the input unit from the controller is recognized as the time interval data by the control unit. Then, the velocity magnitude data of the controller is calculated by the control unit based on the acceleration data and the time interval data, both of which are recognized by the control unit. Next, the velocity magnitude data of the bat character is calculated by the control unit based on the velocity magnitude data of the controller. Accordingly, a state of the bat character, which is displayed on the image display unit, moving at the velocity set by the velocity magnitude data of the bat is continuously displayed on the image display unit with the image data corresponding to the bat character. Also, the coordinate data within the display range of the bat character and that of the ball character are recognized by the control unit. Accordingly, it is judged by the control unit whether or not the coordinate data within the display range of the object moving at the velocity set by the velocity magnitude data of the bat corresponds to the coordinate data within the display range of the ball character. Then, if it is judged by the control unit that the coordinate data within the display range of the bat moving at the velocity set by the velocity magnitude data of the bat corresponds to the coordinate data within the display range of the ball character (if the ball is hit with the bat), the vibration control data for controlling vibration of the controller is calculated by the control unit depending on the velocity set by the velocity magnitude data of the bat. Next, a command for outputting the vibration control data to the controller is issued by the control unit. Accordingly, the controller is caused to vibrate by the vibration mechanism that received the vibration control data.
  • [0022]
    In the game program, it is possible to cause the bat character to move in conjunction with movement of the controller in which the acceleration sensor and the vibration mechanism are embedded. Then, when the ball is capable of being hit with the bat, the vibration control data for the controller depending on the velocity of the bat character is calculated, and the vibration control data for the controller is outputted from the control unit to the vibration mechanism of the controller. Because of this, it becomes possible to cause the controller to vibrate depending on the velocity of the bat character. In other words, it is possible to cause the controller to vibrate by the vibration mechanism depending on the velocity of the object (bat) when the moved object (bat) makes contact with another object (ball).

  • [0025]
    According to the game to be realized by the program, in the another object moving state displaying function, the state of the another object moving at the velocity set by the velocity magnitude data of the another object is continuously displayed on the image display unit with the image data corresponding to the another object. Accordingly, in the vibration control data calculating function, when it is judged by the control unit that the coordinate data within the display range of the object moving at the velocity set by the velocity magnitude data of the object corresponds to the coordinate data within the display range of the another object, the vibration control data for controlling vibration of the controller is calculated by the control unit depending on the velocity set by the velocity magnitude data of the object and the velocity set by the velocity magnitude data of the another object.
  • [0026]
    When a baseball game to be realized by the game program is exemplified, a state of a ball character moving at the velocity set by the velocity magnitude data of the ball character is continuously displayed on the image display unit with the image data corresponding to the ball character.

Then, a command for outputting the vibration control data to the controller is issued by the control unit, and the controller is caused to vibrate by the vibration mechanism that received the vibration control data.
  • [0027]
    In the game program, it is possible to cause the bat character to move in conjunction with movement of the controller in which the acceleration sensor and the vibration mechanism are embedded.

Accordingly, it becomes possible to cause the controller to vibrate depending on the velocity of the bat character and the velocity of the ball character. In other words, when the moving object (bat) makes contact with the another object (ball), it is possible to cause the controller to vibrate by the vibration mechanism depending on the velocity of the object (bat) and the velocity of the another object (ball).

Accordingly, the polygon data is converted into the polygon data in the two-dimensional space (i.e., the two-dimensional polygon data). Then, a polygon outline is constituted with a plurality of two-dimensional polygon data, and the texture data specified by the texture address data is written to the internal area of the polygon. Thus, it is possible to express objects made by applying texture to each polygon, that is, various characters.

    In the case of the image data, the signal processor 8 firstly performs the positional computation, the light source computation, and the like for a character in the three-dimensional space based on the command from the CPU 7. Next, the image processor 9 performs a processing of writing the image data to be rendered to the RAM 12 based on the computation results by the signal processor 8. Then, the image data written to the RAM 12 is provided to the D/A converter 15 through the interface circuit 16. Here, the image data is converted into an analog image signal by the D/A converter 15. Then, the image data is provided to the television monitor 20 and is displayed as an image.
  • [0069]
    In the case of the audio data, the signal processor 8 firstly performs processing to generate and process the audio data based on the command from the CPU 7.

  • Summary of Batting Vibration Control System in Baseball Game and Flow of a Variety of Processing
  • [0085]
    A batting vibration control system in the baseball game will be hereinafter explained. In addition, flow of the batting vibration control system illustrated in FIGS. 10 and 11 will be simultaneously explained.
  • [0086]
    As illustrated in FIG. 3, when a game player operates a batter character in the present baseball game, a pitcher character 71, a batter character 72 holding a bat, a contact hitting cursor area 80 in the reference state are displayed on the television monitor 20 (S1). Here, the initial range data for setting the contact hitting cursor area 80 in the reference state is preliminarily set in the game program, and the initial range data of the contact hitting cursor area 80 is read out of the memory unit 2 and is recognized by the control unit 1.
  • [0087]
    Here, when a signal, which is issued by the controller 25 when a pitching starting corresponding button (not illustrated in the figure) of the controller 25 is pressed, is received by the control unit 1, a command for causing the pitcher character 71 to start pitching is issued by the control unit 1 based on the game program. Accordingly, a state of the pitcher character 71 performing a pitching motion is displayed on the television monitor 20 by causing the image data (e.g., polygon data) corresponding to the pitcher character 72 to consecutively move (S2). Then, when the predetermined pitching motion of the pitcher character 71 is completed, a command for causing the pitcher character 71 to release a ball is recognized by the control unit 1 (S3).
  • [0088]
    Accordingly, the control unit 1 starts recognition of velocity magnitude data VB and the position data of the ball released by the pitcher character 71 (S4). Here, the position data of the ball character 74 is made up of the reference coordinate data indicating the center point (reference point) Bm1 of the ball and the coordinate data within the display range of the ball. Then, a state that the ball character 74 released by the pitcher character 71 moves from the pitcher character 71 to the batter character 72 is displayed on the television monitor 20 based on the reference coordinate data indicating the reference point Bm1 of the ball (S5). The state is realized by causing the image data corresponding to the ball character 74 to move from the pitcher character 71 to the batter character 72, and movement of the ball character 74 is herein controlled by the control unit 1 while the reference point Bm1 is set as the reference.
  • [0089]
    As illustrated in FIG. 4, if a game player moves the controller 25 (e.g., if a game player swings his/her arm together with the controller 25 while holding the controller 25: S6) while a state that the ball character 74 released by the pitcher character 71 moves from the pitcher character 71 to the batter character 72 is displayed on the television monitor 20, acceleration data G detected by the acceleration sensor 24 embedded in the controller 25 is consecutively outputted from the controller 25 to the operation input unit 5 and is inputted into the operation input unit 5 (S7).
  • [0090]
    Accordingly, it is judged by the controller unit 1 whether or not the absolute value of the acceleration data G inputted into the operation input unit 5 is greater than or equal to a predetermined value (S8). If it is judged by the control unit 1 that the absolute value of the acceleration data G is greater than or equal to the predetermined value (Yes in S8), the acceleration data G is recognized by the control unit 1 (S9). Accordingly, a display starting command for a state of the bat moving with the batter character 72, that is, a state of the batter character 72 swinging the bat, is issued from control unit 1 to the image display unit 3. Here, if it is judged by the control unit 1 that the absolute value of the acceleration data G inputted into the operation input unit 5 is less than the predetermined value (No in S8), the acceleration data G is not recognized by the control unit 1 (S1). In other words, the bat does not move with the batter character 72 (the batter character 72 does not swing the bat).
  • [0091]
    When the acceleration data G is sequentially recognized by the control unit 1, a time interval of the acceleration data G consecutively inputted into the operation input unit 5 is recognized by the control unit 1 as the time interval data dt (S11). Accordingly, as illustrated in FIG. 5, the integral calculation is performed by the control unit 1 for the acceleration data G recognized by the control unit 1 with the time interval data dt, and the velocity magnitude data V of the controller 25 is calculated by the control unit 1 (S12). Also, the integral calculation for the velocity magnitude data V of the controller 25 is performed by the control unit 1 with the time interval data dt, and position data X of the controller 25 is calculated by the control unit 1 (S13).
  • [0092]
    Accordingly, the calculation of multiplying the velocity magnitude data V of the controller 25 by the modification coefficient a for the image display is performed by the control unit 1, and velocity magnitude data VBT (α·V) of the bat is calculated by the control unit (S14). Then, the calculation of converting the position data X of the controller 25 into the position data X′ of the television monitor 20 of the image display unit 3 is performed by the control unit 1 (See FIG. 6: S15). Accordingly, a state of the bat moving at the velocity set by the velocity magnitude data VBT of the bat in the position set by the position data X′, that is, a moving state of the bat moving with the batter character 72 (bat swing state), is consecutively displayed on the television monitor 20 by causing the image data (e.g., polygon data) corresponding to the bat to move on the television monitor 20 of the image display unit 3 (S16). Here, the position data of the bat character 73 is recognized by the control unit 1 (S17). Here, the position data of the bat character 73 is made up of the coordinate data indicating the reference point Bm2 of the bat and the coordinate data within the display range of the bat. The position data of the contact hitting cursor area in the display area of the bat character herein corresponds to the position data of the bat character.
  • [0093]
    The state that the bat character is displayed on the television monitor 20 is realized by causing the image data (e.g., polygon data) of the batter character 72 and the bat character 73 to consecutively move on the television monitor 20 at a rendering time interval set by the rendering time interval data so that the bat character 73 moves at the velocity set by the velocity magnitude data VBT of the bat. The rendering time interval data is regulated by the control unit 1 depending on the velocity magnitude data. For example, the reference moving velocity magnitude and the reference rendering time interval (e.g., 0.02 seconds) of the bat on the game screen are preliminarily set in the game program. Under the condition that this reference state is set as the reference, if the moving velocity of the bat is faster than the reference moving velocity, that is, if the moving velocity magnitude of the bat is greater than the reference moving velocity magnitude, the polygon data is displayed on the television monitor 20 at the time interval less than the interval of 0.02 seconds. On the other hand, if the moving velocity of the bat is slower than the reference moving velocity, that is, if the moving velocity magnitude of the bat is less than the reference moving velocity magnitude, the polygon data is displayed on the television monitor 20 at the time interval greater than the time interval of 0.02 seconds. Here, the rendering time interval is calculated by multiplying the reference time interval by rate (ratio) of the calculated velocity magnitude of the bat with respect to the reference moving velocity.
  • [0094]
    After the bat character is displayed on the television monitor 20 as described above, it is judged by the control unit 1 whether or not the coordinate data within the display range of the bat moving at the velocity set by the velocity magnitude data of the bat corresponds to the coordinate data within the display range of the ball (S18). Specifically, it is judged by the control unit 1 whether or not the ball is hit with the bat. Then, as illustrated in FIG. 7, if it is judged by the control unit 1 that the coordinate data within the display range of the bat (within the area of the contact hitting cursor 80) moving at the velocity set by the velocity magnitude data of the bat corresponds to the coordinate data within the display range of the ball character 74 (Yes in S18), distance 1 m between the reference point Bm1 of the ball character 74 and the reference point Bm2 of the bat character is calculated by the control unit 1 (S19). Accordingly, vibration control data S for controlling vibration of the controller 25 is calculated by the control unit 1 depending on the distance 1 m between reference points, the velocity VB set by the velocity magnitude data of the ball, and the velocity set by the velocity magnitude data of the bat (S20). Accordingly, a command of outputting the vibration control data S to the controller 25 is issued by the control unit 1 (S21). On the other hand, if it is judged by the control unit 1 that the coordinate data within the display range of the bat moving at the velocity set by the velocity magnitude data of the bat does not correspond to the coordinate data within the display range of the ball (No in S18), the calculation of the distance 1 m between the reference points is not performed by the control unit 1.

  • [0095]
    When the acceleration data G made up of magnitudes of the accelerations in the triaxial directions is recognized by the control unit 1 and then a time interval of the acceleration data G (gx, gy, gz, t) consecutively inputted into the operation input unit 5 from the controller 25 is recognized by the control unit 1 as the time interval data dt, as illustrated in FIG. 5, the integral calculation is performed by the control unit 1 for the acceleration data G consecutively inputted into the operation input unit 5 from the controller 25 with the time interval data dt, and the velocity magnitude data V (vx, vy, vz, t) of the controller 25 in the triaxial directions is calculated by the control unit 1. For example, when acceleration data G1 (gx1, gy1, gz1, t1) is firstly recognized by the control unit 1 at time t1 and subsequently acceleration data G2 (gx2, gy2, gz2, t2) is recognized by the control unit 1 at time t2, velocity magnitude data V1 (vx1, vy1, vz1, t1) of the controller 25 is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of “∫[G2 (gx2, gy2, gz2, t2)−G1 (gx1, gy1, gz1, t1)]·dt” between the time t2 and the time t1. In a similar way to the above, when acceleration data G3 (gx3, gy3, gz3, t3) is recognized by the control unit 1 at time t3 succeeding the time t2, velocity magnitude data V2 (vx2, vy2, vz2, t2) of the controller 25 is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of “∫[G3 (gx3, gy3, gz3, t3)−G2 (gx2, gy2, gz2, t2)]·dt” between the time t3 and the time t2. Also, when acceleration data G4 (gx4, gy4, gz4, t4) is recognized by the control unit 1 at time t4 succeeding the time t3, velocity magnitude data V3 (vx3, vy3, vz3, t3) of the controller 25 is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of “∫[G4 (gx4, gy4, gz4, t4)−G3 (gx3, gy3, gz3, t3)]·dt” between the time t4 and the time t3.
  • [0096]
    When the integral calculation is further performed by the control unit 1 for thus calculated velocity magnitude data V of the controller 25 with the time interval data dt, the position data X of the controller 25 is calculated by the control unit 1. For example, position data X1 (x1, y1, z1, t1) of the controller 25 is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of “∫[V2 (vx2, vy2, vz2, t2)−V1 (vx1, vy1, vz1, t1)]·dt” between the time t2 and the time t1. In a similar way to this, position data X2 (x2, y2, z2, t2) of the controller 25 is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of “∫[V3 (vx3, vy3, vz3, t3)−V2 (vx2, vy2, vz2, t2)]·dt” between the time t3 and the time t2.
  • [0097]
    It is possible to calculate the velocity magnitude data and the position data of the controller 25 in each time based on the acceleration data G of the controller 25 by causing the control unit 1 to perform the above series of calculations when the acceleration data G of the controller 25 is recognized by the control unit 1.
  • [0098]
    Note that time when the velocity magnitude data V and the position data X of the controller 25 are calculated, time ts at which the acceleration data G of the controller 25 is recognized by the control unit for the first time is set to be the calculation starting time. Also, time te at which it is judged by the control unit 1 that the coordinate set by the within-area coordinate data of the modified range data of the contact hitting cursor area 80 corresponds to at least one of the within-display range coordinate data of the ball that is set by the within-range coordinate data of the ball, that is, time te at which the ball is hit with the bat, is set to be the calculation ending time.
  • Object Moving Velocity Data Calculating Means
  • [0099]
    The velocity magnitude data VBT of the bat is calculated by causing the control unit 1 to perform the calculation of multiplying the velocity magnitude data V of the controller 25 by the modification coefficient α for the image display. This is the processing performed for modifying the velocity magnitude data calculated based on the acceleration data G of the actually moved controller 25 into the moving velocity of the bat used in the game. For example, the velocity magnitude data VBT of the bat is calculated by the control unit 1 by causing the control unit 1 to perform the calculation of multiplying the above calculated velocity magnitude data V1 and V2 of the controller 25 by the modification coefficient α (constant) or the modification coefficient depending on the velocity magnitude data V1 and V2 of the controller 25, that is, the modification coefficient α (V) in which the velocity magnitude data V of the controller 25 is set to be a variable.
  • Object Moving State Displaying Means
  • [0100]
    As illustrated in FIG. 6, the above calculated position data X1 and X2 of the controller 25 are converted into position data X′1 and X′2 for the television monitor 20. The position data X1 and X2 of the controller 25 are coordinates in the three-dimensional real space (space in which a game player swings his/her arm together with the controller 25). Therefore, the calculation of converting the position data X1 and X2 of the controller 25 into the position data X′1 and X′2 for the television monitor 20 in the three-dimensional game space is herein performed by the control unit 1. The conversion is performed by causing the control unit 1 to perform the mapping from the three-dimensional real space to the three-dimensional game space. For example, the conversion is performed by causing the control unit 1 to perform the calculation of “X′ (x′, y′, z′)=f·X (x, y, z)” with the map function f preliminarily determined in the game program. A state of the bat character 73 moving at the velocity VBT set by the velocity magnitude data of the bat in the position set by the position data X′1 and X′2 of the bat in the three-dimensional game space is displayed on the television monitor 20.
  • Object Correspondence Judging Means and Vibration Control Data Calculating Means
  • [0101]
    First, it is judged by the control unit 1 whether or not the coordinate within the display range of the bat moving at the velocity VBT set by the velocity magnitude data of the bat corresponds to at least one of the coordinates within the display range of the ball moving at the velocity VB set by the velocity magnitude data of the ball. Specifically, it is judged by the control unit 1 whether or not an overlapped portion between a predetermined area of the bat character 73 and the display area of the ball character 74 is generated, that is, whether or not the ball is hit with the bat. Then, if it is judged by the control unit 1 that the coordinate within the display range of the bat corresponds to at least one of the coordinates within the display range of the ball, as illustrated in FIG. 7, the distance 1 m between the reference point Bm1 of the ball character 74 and the reference point Bm2 of the bat character 73 is calculated by the control unit 1. Accordingly, the control unit 1 is caused to perform the calculation of synthesizing the velocity VBT set by the velocity magnitude data of the bat and the velocity VB set by the velocity magnitude data of the ball, and as illustrated in FIG. 8, the synthesis velocity data for setting synthesis velocity VG is calculated by the control unit 1.
  • [0102]
    Here, the calculation of reversing the direction of the vector data of the ball is performed by the control unit 1. Then, the control unit 1 is caused to perform the calculation of moving the reference point of the vector data of the bat from the reference point Bm2 of the bat to the reference point Bm1 of the ball. Then, the calculation of synthesizing the vector data of the bat and the vector data of the ball in the reference point Bm1 of the ball is performed by the control unit 1. In this way, the synthesis vector for setting the velocity and the direction of the ball hit back with the bat is calculated by the control unit 1. Note that each vector is calculated by the control unit 1 based on the velocity magnitude of the ball character 74 and that of the bat character 73 when the ball is hit with the bat, and the coordinates of two points in the moving direction.
  • [0103]
    Accordingly, as illustrated in FIG. 9, a first parameter γ1 corresponding to the distance lm between the reference points is selected by the control unit 1 based on a first correspondence table. Then, a second parameter γ2 is selected by the control unit 1 based on a second correspondence table depending on the combination of the synthesis velocity VG and the first parameter γ1. Then, vibration control data S is selected by the control unit 1 based on a correspondence table (here, the second correspondence table) between the second parameter γ2 and the vibration control data S. Here, the vibration control data S includes values ranging from 1 to 7. The vibration control data S is configured to be an indicator for indicating an extent to which the vibration motor 26 is caused to vibrate. As the value of the vibration control data S becomes greater, the number of revolutions of the vibration motor 26 becomes greater. When the vibration control data S is provided from the control unit 1 to the operation input unit 5, it is converted into a motor signal corresponding to the vibration control data S by the operation input unit 5, and thus the vibration motor 26 revolves at the number of revolutions corresponding to the motor signal. In other words, the controller 25 vibrates.
  • [0104]
    Specifically, when the distance 1 m between the reference points is zero, the bat is configured to make solid contact with the ball. Because of this, regardless of the magnitude of the synthesis velocity VG, the controller 25 comes to less vibrate. Also, as the distance lm between the reference points becomes greater than zero, the bat is configured not to have made solid contact with the ball, and the controller 25 comes to more vibrate depending on the magnitude of the synthesis velocity VG.
