Description

  The present invention allows a moving object that is moving from a predetermined movement start position in a virtual three-dimensional game space toward a predetermined area to receive an instruction from a player and act based on the result of the operation. The present invention relates to a control technology for causing a computer to play a battle game.

Conventionally, a game space simulating virtual three-dimensional baseball is displayed on a monitor, and the bat possessed by the self character is moved by moving in the game space, that is, by making the cursor coincide with the ball object thrown by the pitcher character. There is known a baseball game in which an action of an object on a ball object, that is, a hit is determined. In this baseball game, the cursor is arbitrarily movable on the home base by the player operating the cross key of the controller. In recent years, a game employing a controller including an acceleration sensor has been proposed (Patent Document 1). Patent Document 1 proposes a game in which a player shoots a ball object that has been pitched by swinging the controller like a bat. In the case of this game, since the controller and the game machine main body incorporating the control unit adopt a wireless proximity communication method, the player has a high degree of freedom in the game position and the like, and one player can monitor the monitor unit. Multiple people can enjoy the game without occupying it.

  In a conventional baseball game, a cursor indicating the hit position is designated by the controller with respect to the pass position of the pitched ball object on the home base, and it is determined that the ball object has been hit when both positions match. is there. However, since the cursor is a small area of a point or small circle with respect to the strike zone, the position designation operation is performed in terms of short allowable time for position designation and accuracy of position designation on the monitor. Was not always easy. Therefore, compared to the player on the pitcher side (defensive side), there is a tendency that the game operation is relatively difficult for the player on the batter side (attack side), and there is room for improvement in terms of game balance and fun of offense and defense. there were. In particular, in the case of the controller described in Patent Document 1, although there is versatility and freedom of operation, there is a part that depends on the player's sense for fine position designation operation, so it is generally difficult to say, It was also an experience. Therefore, simply adopting a configuration in which the cursor is moved by a controller having an acceleration sensor makes the operation difficult and the game may not be interesting.

  The present invention has been made in view of the above, by tracing the moving object displayed on the monitor with a pointing device, by determining the action condition with the moving object from the obtained amount of tracing, An object of the present invention is to provide a game program, a battle game apparatus, and a battle game control method that alleviate excessive operability for a player with respect to an action result, balance the game operations between the two players, and bring out the fun of the game.

  According to the first aspect of the present invention, an action from a player is received and acted on a moving object that is moving from a predetermined movement start position in a virtual three-dimensional game space toward a predetermined area, and the result of the action is received.

The difference between the displayed position of the moving object and the display position of the moving object is periodically measured as a trace amount, and the respective trace amounts are integrated to obtain a total trace amount. Accordingly, an action condition with the moving object is determined.

  According to these inventions, the moving object is moved from the predetermined movement start position in the virtual three-dimensional game space toward the predetermined area, and an instruction from the player is given to the moving moving object. The game is advanced based on the result of the action. First, at least during the movement of the moving object, the image display control means converts the game space in which the moving start position and the predetermined area are looked down obliquely from above into a two-dimensional space and displayed on the monitor. In this state, the movement trajectory setting means sets the movement trajectory of the moving object with respect to the temporal direction, and the movement processing means moves the moving object in the two-dimensional space according to the set movement trajectory. Here, while the moving body object moves from the movement start position to a predetermined area by the tracing amount measuring means, the instruction coordinates on the monitor obtained from the pointing device via the operation instruction of the player are displayed on the monitor.

  The monitor 21 is connected to the drawing processor 10. The speaker 23 is connected to the amplifier circuit 22. In the case of an arcade video game apparatus, the monitor 21, the amplifier circuit 22, and the speaker 23 may be housed in one housing together with the blocks constituting the consumer game machine 100. The indicator display 24 has, for example, one or a predetermined number of light emitting elements, for example, LEDs that emit infrared light, arranged at predetermined intervals on both ends of a long body having a predetermined length. It is. The indicator display 24 is imaged as a bright spot by an imaging unit 196 of the controller 19 described later, and the position of the bright spot image obtained by imaging the light emitting element (that is, the coordinates (address) in the memory 18 for temporarily capturing the captured image). To function as a position specifying display element for detecting the orientation of the controller 19.

  When the video game apparatus is configured with a personal computer, a workstation, or the like as a core, the monitor 21 corresponds to a computer display. The decompression circuit 7, the drawing processor 10, the audio processor 11, and the like correspond to a part of program data recorded in the recording medium 300 or hardware on an expansion board installed in an expansion slot of a computer. The interface circuit 4, the parallel port 8, the serial port 9, and the interface 13 correspond to hardware on an expansion board mounted in an expansion slot of the computer. The buffers 14 to 16 correspond to the storage areas of the main memory 5 or the expansion memory, respectively.

  Next, each component shown in FIG. 1 will be described. The graphics data generation processor 3 functions as a coprocessor of the CPU 1. That is, the graphics data generation processor 3 performs coordinate conversion and light source calculation, for example, calculation of a fixed point format matrix or vector by parallel processing.

  The main processing performed by the graphics data generation processor 3 includes predetermined data based on the coordinate data, movement amount data, rotation amount data, and the like of each vertex in the two-dimensional or three-dimensional space of the image data supplied from the CPU 1. There are processing for obtaining address data of the processing target image on the display area and returning it to the CPU 1, processing for calculating the luminance of the image in accordance with the distance from the virtually set light source and the inclination with respect to the light source.

  The interface circuit 4 is used for an interface of a peripheral device, for example, a pointing device such as a mouse or a trackball. The main memory 5 is constituted by a RAM (Random ccess Memory). The ROM 6 stores program data serving as an operating system for the video game apparatus.

  The decompression circuit 7 performs decompression processing on a compressed image compressed by intra coding in accordance with the MPEG (Moving Picture Experts Group) standard for moving images and the JPEG (Joint Photographic Experts Group) standard for still images. The decompression processing includes decoding processing (decoding of data encoded by VLC: Variable Length Code), inverse quantization processing, IDCT (Inverse Discrete Cosine Transform) processing, intra image restoration processing, and the like.

  The drawing processor 10 performs a drawing process on the buffer 14 based on a drawing command issued by the CPU 1 every predetermined time T (for example, T = 1/60 seconds in one frame).

  The buffer 14 is composed of, for example, a RAM, and is divided into a display area (frame buffer) and a non-display area. The display area is composed of a development area for data to be displayed on the display surface of the monitor 21. The non-display area is composed of storage areas such as data for defining skeletons, model data for defining polygons, animation data for causing the model to move, pattern data indicating the contents of each animation, texture data, and color palette data. .

  Here, the texture data is two-dimensional image data. The color palette data is data for designating a color such as texture data. The CPU 1 reads and records these data in advance in the non-display area of the buffer 14 from the recording medium 300 at once or divided into a plurality of times according to the progress of the game.

  The drawing command includes a drawing command for drawing a stereoscopic image using a polygon and a drawing command for drawing a normal two-dimensional image. Here, the polygon is a polygonal two-dimensional virtual figure, and for example, a triangle or a quadrangle is used.

  A drawing command for drawing a stereoscopic image using polygons is polygon vertex address data indicating the storage position of polygon vertex coordinate data on the display area of the buffer 14, and the storage position of the texture to be pasted on the polygon 14 on the buffer 14. Is performed on each of the color address data indicating the storage position on the buffer 14 and the color data indicating the texture brightness.

  Among the above data, the polygon vertex address data on the display area is the movement amount data and rotation amount data obtained by the graphics data generation processor 3 from the vertex information of the virtual camera in the three-dimensional space from the CPU 1 from the viewpoint information of the virtual camera. Is converted to polygon vertex coordinate data in two dimensions (from the viewpoint of the virtual camera). The luminance data is determined by the graphics data generation processor 3 based on the distance from the position indicated by the polygon vertex coordinate data after the coordinate conversion from the CPU 1 to the light source virtually arranged.

  The polygon vertex address data indicates an address on the display area of the buffer 14. The drawing processor 10 performs a process of writing texture data corresponding to the range of the display area of the buffer 14 indicated by the three polygon vertex address data.

  An object such as a character in the game space is composed of a plurality of polygons. The CPU 1 stores the coordinate data in the three-dimensional space of each polygon in the buffer 14 in association with the corresponding skeleton vector data. Then, when the character is moved on the display screen of the monitor 21 by an operation of the controller 19 to be described later, the movement of the character is expressed, or the viewpoint position of the virtual camera viewing the character is changed. In addition, the following processing is performed.

  That is, the CPU 1 obtains the graphics data generation processor 3 from the three-dimensional coordinate data of the vertices of each polygon held in the non-display area of the buffer 14, the skeleton coordinates, and the rotation amount data. The movement amount data and the rotation amount data of each polygon are given.

  The graphics data generation processor 3 sequentially obtains the three-dimensional coordinate data after movement and rotation of each polygon based on the three-dimensional coordinate data of the vertex of each polygon and the movement amount data and rotation amount data of each polygon.

  Of the three-dimensional coordinate data of each polygon thus obtained, horizontal and vertical coordinate data is supplied to the drawing processor 10 as address data on the display area of the buffer 14, that is, polygon vertex address data.

  The drawing processor 10 writes the texture data indicated by the texture address data assigned in advance on the display area of the buffer 14 indicated by the three polygon vertex address data. As a result, an object composed of a large number of polygons to which the corresponding texture is pasted is displayed on the display screen of the monitor 21.

  A drawing command for drawing a normal two-dimensional image indicates vertex address data, texture address data, color palette address data indicating the storage position on the buffer 14 of color palette data indicating the color of the texture data, and luminance of the texture. This is performed on the luminance data. Among these data, the vertex address data is obtained by coordinate-converting the vertex coordinate data on the two-dimensional plane from the CPU 1 by the graphics data generation processor 3 based on the movement amount data and the rotation amount data from the CPU 1.

  The audio processor 11 stores ADPCM (Adaptive Differential Pulse Code Modulation) data read from the recording medium 300 in the buffer 15. The ADPCM data stored in the buffer 15 becomes a sound source.

  Also, the audio processor 11 reads ADPCM data from the buffer 15 based on, for example, a clock signal having a frequency of 44.1 kHz. The audio processor 11 performs processing such as pitch conversion, noise addition, envelope setting, level setting, and reverb addition on the read ADPCM data.

When the audio data read from the recording medium 300 is PCM (Pulse Code Modulation) data such as CD-DA (Compact Disk Digital Audio), the audio processor 11 converts the audio data into ADPCM data. Further, the processing for the PCM data by the program is directly performed on the main memory 5. The PCM data processed on the main memory 5 is supplied to the audio processor 11 and converted into ADPCM data. Thereafter, the various processes described above are performed, and sound is output from the speaker 23.
As the recording medium drive 17, for example, a DVD-ROM drive, a CD-ROM drive, a hard disk drive, an optical disk drive, a flexible disk drive, a silicon disk drive, a cassette medium reader, or the like is used. In this case, as the recording medium 300, a DVD-ROM, a CD-ROM, a hard disk, an optical disk, a flexible disk, a semiconductor memory, or the like is used.

  The recording medium drive 17 reads image data, audio data, and program data from the recording medium 300 and supplies the read data to the decoder 12. The decoder 12 reproduces data from the recording medium drive 17, further performs error correction processing by ECC (Error Correction Code), and supplies the data subjected to the error correction processing to the main memory 5 or the audio processor 11.

  For example, a card-type memory is used as the memory 18. The card-type memory is used, for example, for holding various game parameters at the time of interruption in order to hold the state at the time of interruption when the game is interrupted.

  The controller 19 has a shape that can be gripped by the player, for example, a bar-shaped outer shape, and various operation portions are provided at appropriate positions on the surface. The controller 19 is an operation device used by the player to input various operation commands, and sends an operation signal according to the operation of the player to the CPU 1. The controller 19 includes an interface 191, an acceleration sensor 192, and an operation rod (joystick) 194 capable of detecting a tilt direction and an angle in the 360 ° direction, and four directions (cross direction) as an operation part. A detectable cross key 195 is provided. In addition, the controller 19 includes an imaging unit 196 that is an area sensor that receives infrared light from within a required visual field width, and includes a CMOS sensor having an imaging surface in front of the longitudinal end of the main body. ing. Note that the interface 191 is configured by a circuit that transmits a wireless signal for proximity communication using infrared rays, radio waves, or the like, for example, and converts an operation signal transmitted from the controller 19 into a wireless signal and transmits the wireless signal to the interface 13.

  The acceleration sensor 192 includes a triaxial acceleration sensor, and detects each acceleration in the triaxial direction as an acceleration signal. The acceleration sensor 192 detects at least the orientation and orientation of the controller 19. As the acceleration sensor 192, for example, an acceleration sensor such as a piezoresistive type, a capacitance type, or a magnetic sensor type can be adopted.

  The joystick 194 is used, for example, to give the CPU 1 a command for moving a character, an object, a cursor or the like on the screen of the monitor 21 in the vertical, horizontal, or diagonal directions as will be described later.

  The button 193 and the cross key 195 of the controller 19 are configured by an on / off switch that is turned on when pressed from the neutral position by an external pressing force, and returns to the neutral position and turned off when the pressing force is released. The

  FIG. 3 is a partial external view of the controller 19. For example, a joystick 194, a cross key 195, a button 193, and the like are sequentially disposed on one side surface of the long portion of the controller 19 from the front end side, and an imaging unit 196 is disposed on the front end surface.

  The image pickup unit 196 picks up at least a region including the light emitting elements of the monitor 21 screen and the indicator display 24 away from the screen of the monitor 21 by a required distance (a normal distance when playing a game, for example, about 1.5 m). A visual field width that can be obtained.

  4A and 4B are diagrams for explaining a method of calculating the visual field width and the orientation of the controller 19, FIG. 4A is a front view of the monitor 21, and FIG. 4B is an example of the contents stored in the memory 18 after imaging. FIG. In FIG. 4A, when the controller 19 is directed to the point O1 at the top of the monitor 21 screen, the point O1 and the indicator display 24 need to be within the field of view. Further, when the controller 19 is directed to the point O2 on the left side of the monitor 21 screen, the point O2 and the indicator display 24 need to be within the visual field. When the controller 19 is directed to the point O3 at the lower part of the screen of the monitor 21, the point O3 and the indicator display 24 need to be within the field of view. When the controller 19 is directed to the point O4 on the right side of the monitor 21 screen, the point O4 and the indicator display 24 need to be within the field of view. Therefore, in order to detect all points on the screen of the monitor 21, the imaging unit 196 needs to have a visual field width corresponding to at least the horizontal width of the frame W1 and the vertical width of the frame W2.

  FIG. 4B shows the contents of the memory 18 when the controller 19 is pointed at an arbitrary point Oa on the monitor 21 screen. The point O ′ is the center coordinate Q0 (X0, Y0) of the memory 18, and the images Q1 and Q2 of the light emitting elements of the indicator display 24 are displayed above it.

When the recording medium 300 is loaded in the recording medium drive 17, when a power switch (not shown) is turned on and the video game apparatus is turned on, the CPU 1 is based on the operating system stored in the ROM 6. The recording medium drive 17 is instructed to read the game program from the recording medium 300 to the main memory 5. As a result, the recording medium drive 17 reads image data, audio data, and program data from the recording medium 300 to the decoder 12. The read image data, audio data, and program data are subjected to error correction processing by the decoder 12 for each data.

  The image data is subjected to error correction processing by the decoder 12 and supplied to the decompression circuit 7 via the bus line 2. The image data that has been subjected to the above-described decompression processing by the decompression circuit 7 is supplied to the drawing processor 10 and written into a non-display area of the buffer 14 by the drawing processor 10. The audio data is subjected to error correction processing by the decoder 12 and written to the buffer 15 via the main memory 5 or the audio processor 11. Program data that has been subjected to error correction processing by the decoder 12 is written into the main memory 5.

  Thereafter, the CPU 1 advances the video game based on the game program stored in the main memory 5 and the content instructed by the player using the controller 19. That is, based on the content that the player instructs using the controller 19, the CPU 1 appropriately controls the change of the game situation, the image processing control, the sound processing control, the internal processing control, and the like based on this.

  As image processing control, for example, the calculation of the coordinates of each skeleton or the calculation of the vertex coordinate data of polygons from the pattern data corresponding to the animation instructed to the character, the obtained three-dimensional coordinate data and the graphics data of the viewpoint position data Supply to the generation processor 3, issue of a rendering command including address data and luminance data on the display area of the buffer 14 obtained by the graphics data generation processor 3 are performed.

  As control of audio processing, for example, issue of an audio output command to the audio processor 11, specification of level, reverb, etc. are performed. As control of the internal processing, for example, calculation according to the operation of the controller 19 is performed.

  FIG. 5 is a diagram showing an example of an image displayed on the monitor 21 in the video game apparatus. First, an outline of a baseball game when a baseball game is played using this video game apparatus will be described. In the baseball game executed in the present invention, generally, two players hold the controller 19 and issue operation instructions, respectively, so that the attacking side and the defensive side are alternately handled to obtain a score. This is a battle game in which a predetermined number of innings are executed for a defensive action for not giving a score and a defensive action for not giving a score, and a total of the points obtained in each inning compete for victory or defeat. One of the players may be a team composed of virtual players controlled by a computer. In this case, the team on the computer side is only the defensive side, and depends on each character (pitcher character or fielder character) on the defensive side. Execute defensive action. No attack period is provided on the CPU 1 side, and a virtual attack result is set.

  As shown in FIG. 5, the baseball game is played in a baseball field set as a virtual three-dimensional game space. In this embodiment, the base screen of the game has a pitching mound and a home base. The virtual camera is set so as to look down from above and obliquely upward from behind the home base, and the line of sight is directed toward the home base with a required angle of view. On the home base, a frame object 60 indicating a pitching area having a predetermined size is set in a posture standing in the game space and is normally displayed. Note that the position of the virtual camera is not limited to the rear of the home base, and an appropriate oblique upper position can be set. However, in the case of this embodiment, the home base side is closer to the attacking player in perspective. Since the vicinity of the hitting position is relatively enlarged, it is preferable for visual recognition.

  The pitcher character 71 throws the ball object 72 as the moving object toward the frame object 60, and the batter character 73 as the action character has the significance as the bat object 74 (part of the action character). ), That is, the batter character 73 applies an action (that is, a hit) to the moving ball object 72 via the bat object 74.

  The frame object 60 indicates a range corresponding to the strike zone on the home base. The frame object 60 is used as an index of the pitching range by the pitcher, and is used for designating the pitching position. The cursor 80 is a circle or an ellipse having a predetermined small diameter, and is movable on the screen in a direction corresponding to the tilting operation of the joystick 194 of the controller 19. It should be noted that the cursor 80 is not particularly necessary in the case where the pitching position is not specified, but in this embodiment, the pitching position is specified.

  Furthermore, in the present embodiment, a sphere type (for example, a straight ball or various changed spheres) can be set using the cross key 195. In the example of FIG. 5, the ball-type notation image 75 includes a ball mark simulating a ball and three arrow marks pointing up and down and right around the ball mark. The arrow mark indicates a ball type that can be selected by the pitcher character. In the example of FIG. 5, the up arrow mark indicates a straight line, the right arrow mark indicates a slider, and the down arrow mark indicates a fork. In addition, there may be a shot, a curve, and the like. If there are more than three types of changing spheres, the shape of the arrow mark may be changed, and more types of changing spheres can be selected if the button 193 is pressed and not pressed and the cross key 195 can be selected. Can be specified. In addition, the designation of the ball type is not to change the selected arrow mark to another color or to change the brightness so that the attacking player does not know, but only to confirm the designation operation, For example, a mode in which the center ball mark changes to another color, the luminance changes, or the designation operation is accepted by voice may be notified.

  The pointer 81 is moved on the screen of the monitor 21 by the controller 19 operated by the attacking player as will be described later. As will be described later, the bonus gauge 82 is used for tracking the display position of the moving ball object 72 every moment according to the set movement locus so as to trace two-dimensionally using the pointer 81, as will be described later. This shows how the increased state changes due to the skill of tracking.

  The timing for designating the pitching position is not particularly limited, but in this embodiment, it is before the pitching instruction. The order of the pitching position designation and the ball type designation is not particularly limited. The cursor 80 is operated so as to be movable on the screen of the monitor 21 by the joystick 194, and when a button 193 is pressed at a certain time, the display position of the cursor 80 is set as the pitching position. Also in this case, no special display is performed so that the pitching position is not known to the attacking player.

  On the other hand, the player on the attacking side moves the pointer 81 by tracing the direction of the controller 19 from the start of pitching to trace the ball object 72. This operation is performed until the ball object 72 reaches the frame object 60 or a hit instruction operation is performed by the button 193. Depending on the skill of the tracing state, the power (action force) and the meet force for hitting the ball object 72 when the button 193 is pressed are set. When the ball object 72 is hit back, the CPU 1 calculates the hitting speed and direction of the ball object 72, and the CPU 1 instructs the batter side and the defensive character according to the rules of the baseball game. Deployment that simulates baseball is realized. For example, if you hit a hit with a runner in 3rd base, the 3rd runner will go home and get a score. On the other hand, if the stroking state is insufficient or the timing of hitting is deviated, the swing is lost. If the button 193 is not pressed (no hitting instruction), the postponement is made.

  In this way, the operation from the player on the pitcher side is permitted, for example, from the time when the designation operation of the ball type and the throwing position is permitted until the series of actions after the hitting is processed as one sequence, and the result of each sequence Accordingly, a baseball game up to a strike count, a ball count, a predetermined out count, and a predetermined inning number proceeds. In FIG. 3, the pitching history and the outcount number are displayed at a suitable place on the screen of the monitor 21, for example, the lower right, and the score and the number of elapsed innings of both teams up to the present time are displayed at other suitable places, for example, the upper left. And are displayed. As will be described later, in one sequence, the display of the screen in FIG. 5 is maintained from the start of the sequence until the end of the hitting.

  Next, main functions of the video game apparatus when a baseball game is played using the video game apparatus configured as described above will be described. FIG. 2 is a main functional block diagram of the video game apparatus shown in FIG.

  As shown in FIG. 2, the video game apparatus includes a CPU 1 that is a program execution unit, and is connected to a controller 19 and a monitor 21. In addition, the CPU 1 stores an image storage unit 141 that stores various image data captured from the storage medium 300, and a player data storage unit 142 that stores player data of the player side team or both teams appearing in the baseball game. And a main memory 5 having a program storage unit 51 for storing game program data fetched from the storage medium 300. The image storage unit 141 includes a frame object 60, a pitcher character 71, a ball object 72, a batter character 73, a bat object 74, a ball type notation image 75, a cursor 80, a pointer 81, a bonus gauge 82, a baseball field background image, and baseball. Various image data necessary for playing the game are stored. Here, as the image data of the background image of the baseball field, for example, image data created in advance by rendering a virtual three-dimensional model created in advance in the virtual three-dimensional space from the viewpoint of the virtual camera may be adopted. it can.

  Among the player data stored in the player data storage unit 142, in particular, player parameters indicating the ability for a baseball game include those relating to batting, and in the case of a pitcher, various items relating to pitching are included. For example, “meet” and “power” are included as those related to the batter (fielder), and “ball speed” parameters are included as related to the pitcher. The player data storage unit 142 also stores batting ratio, batting points, the number of home runs, etc., which are individual results of each player character, and is updated as the game progresses.

  In the case of the pitcher side, the controller 19 outputs a pitching instruction signal to the CPU 1 as a pitching instruction signal when the player inputs a pitching command for instructing the start of pitching by pressing the button 193. Further, the controller 19 outputs a pitching position designation signal to the CPU 1 when an operation signal for designating a pitching position is input by the player when the joystick 194 is tilted.

  On the batter side, the controller 19 outputs a batting instruction signal to the CPU 1 when the batting command for determining the batting timing is input by the player when the button 193 is pressed. Further, the controller 19 outputs an acceleration signal detected by the acceleration sensor 192 to the CPU 1 when the controller 19 itself is moved by the player (for example, moved in a direction or a direction in which the posture is changed). For example, the controller 19 may output an acceleration signal at regular time intervals, or may output an acceleration signal when acceleration is detected by the acceleration sensor 192.

  The CPU 1 executes a game program stored in the main memory 5 to acquire an operation signal received from the controller 19 as a digital signal. And the image display control unit 103 that displays a game image along the game progress on the monitor 21.

  Further, the CPU 1 executes a game program stored in the main memory 5 to thereby set the frame object 60 on the home base, the index frame setting unit 104, and the cross key of the controller 19 operated by the defensive player. A ball type setting unit 105 that sets the ball type of the ball object 72 to be thrown by the pitcher character 71 by an operation signal from 195, a joystick 194 of the controller 19 operated by a player on the defensive side, and a frame object 60 by an operation signal from the button 193 A throwing position setting unit 106 for setting a desired position as a pitching course, and a throw for throwing the ball object 72 against the pitcher character 71 by an operation signal from the button 193 of the controller 19 operated by the player on the defensive side Pitching instruction unit 107 gives a command to start the packaging operation, serves as a movement processing unit 108 to the ball object 72 performs track calculation and transfer processing passes the setting position of the frame object 60 which cast the pitcher character 71.

  Further, the CPU 1 executes a game program stored in the main memory 5, whereby a two-dimensional distance difference between the display position of the pointer 81 and the position of the moving ball object 72 on the monitor 21 screen. The batter character is calculated based on the operation signal from the button 193 of the controller 19 operated by the attacking player, and the tracing amount measuring unit 109 that calculates the total amount of tracing by periodically calculating the amount of tracing as a tracing amount. The batting instruction unit 110 for instructing the batting motion (swing motion to the bat object 74) 73, and the batting condition setting unit for changing and setting the “power” parameter and the “meeting” parameter of the batter character based on the obtained total amount of tracing. 111. Based on the batting instruction from the batter character 73, the batting result (action result) is calculated. In addition, when the bat object 74 hits the ball object 72 (not swinging or not seeing off), for example, a process of dynamically calculating the hitting speed and hitting direction of the ball object 72, for example, each player character and runner on the defensive side It functions as a result processing unit 112 that executes a process of producing the scolding process when there is a game according to the rules of baseball.

  The acquisition unit 101 receives an acceleration signal, a batting instruction, a pitching instruction signal, and a pitching position designation signal output from the acceleration sensor 192, the button 193, the joystick 194, and the cross key 195 of the controller 19 via interfaces 191 and 13 (not shown). And a ball type designation signal. Although only one side is shown in the figure, the interface 13 identifies and receives signals from the controllers 19 possessed by the two players playing the baseball game, respectively.

  The game progress control unit 102, from the start to the end of the game, more specifically, a baseball team (player member) selection process for executing the baseball game, a game start process, and the pitcher character 71 throws the ball object 72. The batter character 73 uses the bat object 74 to hit the moving ball object 72 after throwing, and one sequence of processing until the processing by the result processing unit 112 is completed. For example, the offense and defense are exchanged in 3 outs (1 inning), the final inning is executed up to 9 innings, and the results of both teams, that is, up to the winning / losing determination process by the final score are executed.

  The image display control unit 103 displays a two-dimensional image from the viewpoint of the virtual camera on the monitor 21. The image display control unit 103 provides the drawing processor 10 with a background image, a frame object 60, a pitcher, batter characters 71 and 73, a ball, bat objects 72 and 74, and a ball type set in the game space as the game progresses. The notation image 75, cursor 80, pointer 81, and bonus gauge 82 are displayed.

  When the bat object 74 hits the ball object 72, the image display control unit 103 is configured so that the ball object 72, which is preferably a hit ball, can be tracked by the player, that is, within the field frame of the screen of the monitor 21. By controlling the position and visual field direction of the virtual camera by the program, the game image is displayed and the result processing content is displayed.

  The index frame setting unit 104 sets a frame object 60 having a predetermined shape, here, a rectangle of a predetermined size, on the home base in the game space. The frame object 60 serves as an index for pitching, and is directed at a right angle to the movement start position of the ball object 72 corresponding to the mound.

  The ball type setting unit 105 sets the ball type according to an operation signal from the cross key 195 or from the cross key 195 and the button 193 operated by a player who refers to the ball type notation image 75.

  The pitching position setting unit 106 displays the cursor 80 so as to be movable on the monitor 21, and designates the pitching position of the ball object 72 thrown by the pitcher character 71, and is operated by the joystick 194 of the controller 19. The position is designated by the cursor 80, and the designated position is determined by pressing the button 193. The designated position information is applied to the calculation of the hitting speed and direction in the result processing.

  The pitching instruction unit 107 instructs the pitcher character 71 to start a pitching motion by pressing a button 193.

  The movement processing unit 108 calculates a trajectory for the ball object 72 thrown by the pitcher character 71 to pass the set position with respect to the frame object 60, and in the time direction in the game space of the ball object 72 according to the calculated trajectory. The moving process is performed by sequentially installing position information. Then, the image display control unit 103 displays the ball object 72 on the monitor 21 based on the position information obtained by the trajectory calculation. The trajectory calculation may use a pitcher character's “ball speed” parameter, and may use a normal motion equation or an approximate expression. The trajectory calculation may be performed after the ball type and pitching position are specified, but the position information of the trajectory calculated in advance is stored in a required storage unit, and information corresponding to the specified content is sequentially read out to the movement processing unit 108. Thus, the ball object 72 may be displayed on the monitor 21. The standard moving speed of the ball object 72 on the monitor 21 screen is preferably set to a speed at which the skill level of the tracing operation by the player becomes apparent.

  The tracing amount measuring unit 109 determines the position where the orientation of the controller 19 and the screen of the monitor 21 intersect based on an analysis process for extracting a bright spot image captured by the imaging unit 196 of the controller 19 operated by the attacking player. The pointer 81 is displayed at the specific position, and the two-dimensional distance difference between the display position of the pointer 81 on the monitor 21 screen and the display position of the ball object 72 moving on the monitor 21 screen is specified. Is calculated periodically as the amount of tracing, that is, the total amount of tracing is obtained by integrating each amount of tracing until reaching the frame object 60 from the start of pitching or when there is a batting instruction.

FIG. 6 is a diagram for explaining a method of calculating the stroke amount, and shows a display state of the pointer 81 at a certain point in time for the moving ball object 72 on the screen of the monitor 21. In this state, it is assumed that the pointer 81 is operated so that the player on the batter side overlaps the direction of the controller 19 with the ball object 72. Since the ball object 72 is moving, the operation of placing the pointer 81 on the ball object 72 is a tracing operation. At some point, if the coordinates of the display position of the ball object 72 are B (x1, y1) and the coordinates of the display position of the pointer 81 are P (x2, y2), the distance difference dL between them is dL = √ {(x1 ^{-x2) 2 + (y1-y2} ) obtained as ^2}. Then, such a calculation or a simple expression approximating this calculation expression is used until the ball object 72 reaches the frame object 60 after the ball object 72 starts to move or until a batting instruction is given. This is executed every predetermined cycle (for example, 1/60 second) until the earlier point.

  The measurement of the amount of tracing or the total amount of tracing may be a method of simply integrating the calculated distance difference dL, but in the present embodiment, a method of giving points when a predetermined condition is satisfied for each detection as follows. Is used as an evaluation method instead of a method that uses the total value of direct distance differences. Specifically, the threshold for the distance difference dL is changed depending on whether or not the detected coordinate P (x2, y2) is located behind the coordinate B (x1, y1). A predetermined threshold value is employed when the vehicle is not located rearward, while a threshold value is employed more strictly when the vehicle is located rearward. This is because the operation of tracing the past trajectory of the ball object 72, that is, the operation of chasing the ball trajectory is easy, and the conditions are made stricter accordingly. Various modes can be considered for determining whether or not the current position corresponds to the rear.

  For example, in FIG. 5 (or FIG. 6), since the positional relationship between the pitcher character 71 and the home base display is fixed during the pitching, in this example, the past trajectory direction from the current position of the ball object 72. For x, the values of the x and y coordinates have a predetermined relationship. For example (assuming that the upper left of the monitor 21 is the reference position), the x coordinate is smaller than the current value, the y coordinate is substantially the same as the current value, and so on. When such a condition is met, a severe condition, for example, the radius of the displayed ball object 72 is set as a threshold, and otherwise, the diameter of the displayed ball object 72 is set as a threshold. Alternatively, instead of using the displayed size of the ball object 72, the threshold value may be set using diameter data on the data of the ball object 72 set in advance.

  The threshold value is not limited to the size of the ball object 72, and may be set as two predetermined threshold values (first and second threshold values: first threshold value <second threshold value). Alternatively, the presence or absence of the past side of the trajectory may not be used as a determination factor, and may be determined based on whether or not the difference is within a predetermined distance. Furthermore, as another method of determining whether or not the current position corresponds to the rear, a method of calculating a distance difference from past trajectory data can be considered. If it is within the threshold, a gauge point for bonus gauge, for example, 1 point is awarded.

  As described above, in this embodiment, the distance difference (tracing amount) obtained in each cycle is compared with the threshold value, and if it is within the threshold value, it is given as a gauge point converted for the bonus gauge. The gauge points are sequentially accumulated for each detection, and finally set as a total amount of tracing for evaluating the tracing result. In the present embodiment, the greater the total tracing amount that is the integrated value of the gauge points, the more sophisticated the tracing operation. Processing is simplified by converting to gauge points and performing accumulation processing.

  The batting condition setting unit 111 associates the total amount of stroking with the batting ability of the batter character 73. The total amount of stroking is reflected in the “power” parameter and the “meet” parameter among the player parameters as batting ability. In other words, the values of the “power” parameter and the “meet” parameter stored in advance for each batter character 73 in the player data storage unit 142 are stored in advance as a table, for example, in the buffer 14 so that the smaller the total amount of tracing, the larger the value. It is written in the program storage unit 51. Or you may make it apply to a hit result by changing suitably, for example using the coefficient written beforehand and multiplying this. For example, the total amount of tracing is ranked into a plurality of predetermined stages, and values for the “power” parameter and the “meet” parameter are associated with each rank.

Table 1 shows an example of the relationship between the gauge point corresponding to the total amount of tracing, the meat parameter, and the power parameter.

  As shown in Table 1, when the gauge point is “0”, the meet parameter is “10”, the power parameter is “100”, and each time the gauge point is increased by “10”, the meet parameter is “2”. The power parameter is increased by “5”. When the gauge point is “100”, that is, when the tracing operation is within a predetermined threshold in all the tracing detection cycles, the meat parameter is set to “30” and the power parameter is set to “150” as the maximum conditions. Yes. Note that the gauge point stage is not limited to “10”, and various values can be adopted. The increments of the meet parameter and power parameter can be set to predetermined values, and the difference is not equal. May be. In addition, the total of gauge points has an upper limit of “100”.

  The result processing unit 112 performs a batting result calculation process that is a series of processes after the batting. One of the hitting results processing is to determine whether or not the bat object 74 has hit the ball object 72, and when hitting, the parameters set by the hitting condition setting unit 111, the ball speed of the ball object 72, and the hitting instruction timing. Based on this, for example, the hitting speed and hitting direction of the ball object 72 are dynamically calculated. The determination of whether or not the bat object 74 has hit the ball object 72 depends on the rank corresponding to the total amount of tracing in addition to the timing of the hitting instruction. If there is no batting instruction, it is processed as a postponement.

  In this embodiment, the hitting speed is determined by determining whether the ball object 72 hits the bar-shaped bat object 74 at a right angle, the amount of deviation from the true core, and the player parameters “meet”, “power”, or other parameters. Calculated to reflect By using the hit instruction timing (early hitting to swing feed) and these parameters, the hitting direction is returned to each direction of the baseball field. For example, it becomes “Goro to the 1st base” or “Long over long hit”. Whether or not a hit is made is processed by reflecting the fielder's defensive position, the “defense ability” parameter of the player parameter, etc. in addition to the power and direction. Note that the CPU 1 has a random number generator inside, and uses a random number generated for each sequence to add variation to the striking condition and striking result, so that the game changes so that the same result is not necessarily obtained even under the same condition. Giving sex.

  As the batting result processing by the result processing unit 112, the movement of each player character on the defensive side (catch, return ball, etc.) accompanying the batting and the running process when there is a runner are executed according to the rules of baseball, And the process which instruct | indicates an effect display to the image display control part 103 is performed.

  Next, game processing executed by the CPU 1 based on the game program will be described using a flowchart. FIG. 7 is a flowchart showing the entire process of the game. First, in step S1, the CPU 1 performs initial settings for starting the game. For example, the battle team selected by both players and the display of the player list on the monitor 21 are displayed. Next, image data of the game space, each character, each object, etc. is read and displayed on the monitor 21 (step S3).

  In this state, a sequence is started (step S5), and then a battle process is executed (step S7). Upon completion of the result process, a sequence end process is performed (step S9). Then, it is determined whether or not the result of this sequence is a strike (step S11). If not, the process returns to step S5 to execute a sequence for the next pitch. On the other hand, if it is a triple strike, it is determined whether or not it is 3 out (step S13). If it is not 3 out, the batter character of the next batting order is set (step S15), and the process proceeds to the next sequence (step S5). . On the other hand, if it is 3 out in step S13, it is determined whether or not it is a game set (step S17). If it is not a game set, an offense / defense replacement process is executed (step S19), whereas if it is a game set, a game end process is executed (step S21).

  FIG. 8 is a flowchart of a battle process executed by the CPU 1 based on the game program. First, whether or not an operation signal is input from the controller 19 is checked. That is, it is determined whether or not a ball type designation signal is input (step S31), whether or not a pitching position designation signal is input (step S35), and whether or not a pitching instruction signal is input (step S39).

  If it is determined that the ball type designation signal is input, the ball type is set (step S33). If it is determined that the pitch position designation signal is input, the pitch position is set (step S37). If it is determined that the pitching instruction signal has been input, the pitcher character 71 is caused to perform a pitching motion (step S41).

  Next, the tracing amount detection process is started (step S43), the detected tracing amount is integrated with the tracing amount obtained immediately before (step S45), and the integrated amount is reflected in the gauge amount of the bonus gauge 82 (step S45). Step S47). Next, the presence / absence of a hitting instruction is determined (step S49). If there is no hitting instruction, it is determined whether or not the ball object 72 has passed the frame object 60 (step S51). If it is determined that the ball object 72 has passed the frame object 60, a see-through process is performed (step S53). On the other hand, until the ball object 72 passes through the frame object 60, the process returns to step S43, and the tracing amount integration process is repeated at a predetermined cycle.

  If it is determined in step S49 that there is a batting instruction, it is determined whether or not the batting timing is coincident (step S55), and the batting timing, that is, when the ball object 72 passes over the home base (or If a batting instruction is not given within a minute predetermined period), it is processed as an idle swing (step S55).

On the other hand, if the hitting timings coincide, the hitting speed and hitting direction (hitting condition) are set based on parameters such as “power” and “meet” according to the total amount of stroking (step S59). The hit result processing is executed (step S61).

  FIG. 9 is a flowchart of the tracing amount detection process executed by the CPU 1 based on the game program. First, it is determined whether or not the detected position of the pointer 81 is on the past side with respect to the current coordinate position of the ball object 72 (step S71). It is determined whether it is within the radius of (step S73). If the distance dL is within the radius, the gauge point “1” is given (step S75), and this flow is finished.

  On the other hand, if it is determined in step S71 that the detected position of the pointer 81 is not in the past with respect to the current coordinate position of the ball object 72, then whether or not the distance dL with the ball object 72 is within the diameter of the ball object 72 is determined. Is determined (step S77). If the distance dL is within the diameter of the ball object 72, a gauge point “1” is given (step S75), and this flow ends. If the determinations in step S73 and step S77 are negative, no gauge points are awarded.

  Then, in the tracing amount integration process of FIG. 8, a gauge point addition process is executed for each detection period (step S45), and a bonus gauge 82 is displayed corresponding to the integrated value (step S47).

  In addition, the following aspects are employable for this invention.

(1) In the present embodiment, the hit designation operation is performed. However, the skill of the tracing operation may be reflected in the hit timing.

(2) In the present embodiment, the imaging unit 196 and the indicator display 24 are used as a pointing device, and the tracing operation is performed remotely. However, the pointing device is not limited to such a structure, and the tracing operation is directly performed. It may be an embodiment. For example, a transparent pressure-sensitive member having a film shape is laminated on the screen of the monitor 21, and the ball object 72 displayed on the screen of the monitor 21 is directly traced with a pressing member such as a fingertip or a touch pen. May be obtained. Further, although a part of the pointing device is provided in the controller 19, it may be a separate member.
