  In the conventional golf game, when various conditions such as a club, a hit point position, power, and timing are set, the golfer starts swinging and the ball is hit back by the club. Based on these conditions, the trajectory of the ball is calculated, and the arrival position of the ball is determined as a predetermined position. That is, in the conventional golf game, for example, when conditions such as a club, a hitting point position, power, and timing are set, the ball reaches a predetermined position corresponding to these conditions.

  On the other hand, with the development of game devices in recent years, attempts have been made to reproduce real world golf as faithfully as possible in golf games. Here, one of the problems when trying to reproduce real world golf is uncertainty when a real world golfer shoots a shot.

  For example, in a conventional golf game, if the conditions such as power and timing when the player shots are the same, the reaching position of the ball is also the same. However, in real-world golf, even if you intend to have shots with the same power and timing, the ball does not necessarily reach the same position due to the golfer's psychological state or the influence of force majeure winds and airflows. . Conventional golf games do not reflect the concept of uncertainty of real-world golf and have poor reality.

  The present invention has been made in view of such a problem, and an object of the present invention is to realize a more realistic game by incorporating the concept of uncertainty.

A game program according to claim 1 is a computer capable of executing a game for moving a moving object to a target position by causing a character to act on the moving object based on an instruction from the player. It is a program for realizing the function.
(1) An environment forming function for arranging environmental objects forming the game environment in the game space.
( 2 ) A character placement function for placing a character in the game space.
( 3 ) A moving object placement function for placing objects for moving objects in the game space.
( 4 ) A reaching target setting function for setting a target position of an object for a moving object in a game space based on an instruction from a player.
( 5 ) A reach range setting function for setting a reach range in which the object for the moving body reaches in the game space based on the target position before the character acts on the object for the moving body.
(6) It is determined whether or not the outer edge of the predetermined environmental object and the target position of the reaching range are less than a predetermined distance, and the outer edge of the predetermined environmental object and the target position of the reaching range are predetermined. A reach range changing function for changing the shape of the reach range so that the reach range is expanded toward a predetermined environment object when the distance is less than the distance.
( 7 ) Probability distribution for determining the arrival position where the object for the mobile object arrives is set. In this probability distribution, the probability decreases as the distance from the target position is increased within the reachable range, and for the mobile object The arrival position setting function for setting the arrival position where the object for the moving body arrives by changing the probability distribution based on the state in which the character acts on the object.
( 8 ) A moving body that issues a command to start moving the moving object after the character has acted on the moving object, and controls the moving object toward the reaching position in the game space. Control function.

  Here, a case where this game program is applied to a golf game will be described as an example. For example, a golf game in which a ball object (hereinafter referred to as a ball) is moved to a target position by causing a golfer character (hereinafter referred to as a golfer) to swing based on an instruction from a player is executed on the computer.

In this game, first, environmental objects that form the environment of a golf game are placed in the game space. The ball and golfer are then placed in the game space. Then, when the player operates an input unit such as a controller, the target position of the ball is set in the game space. The target position of the ball can be set at any place on the fairway using a cursor (notifier), for example. For example, if you are aiming directly at a pin and there is a pond or bunker in the foreground and you want to avoid the risk, you can operate the controller to bypass the pond or bunker to the right (or left) of the fairway. ) And move the screen to set the target position. In this case, for example, the camera viewpoint that has the entire fairway in view is panned to the right (or left).

The reach range of the ball is set in the game space corresponding to the target position of the ball. The reach range is set in size and shape according to the target position of the ball. Then, the shape of the reachable range is changed according to the positional relationship between a predetermined environmental object such as a bunker or water hazard and the reachable range. For example, when the reachable range is located near a bunker or a water hazard, the reachable range is expanded toward the bunker or the water hazard. More specifically, it is determined whether or not an outer edge of a predetermined environmental object such as a bunker or a water hazard is less than a predetermined distance. Then, when the outer edge of the bunker or water hazard and the target position of the reach range are less than the predetermined distance, the shape of the reach range is changed so that the reach range expands toward the bunker or water hazard. The

  Further, a probability distribution for determining the arrival position where the ball arrives is set within the reach range. For example, the probability distribution is set such that the probability of the ball reaching the vicinity of the target position is the highest, and the probability of the ball reaching the lower the further away from the target position. To give a very simple example, 7 out of 10 shots are somewhere near the target position, 2 are somewhere outside the area near the target position, and 1 ball is outside the area near the target position. It is an image of reaching somewhere in the area.

  Also, the probability distribution is changed based on the state where the club hits the ball. Specifically, the probability distribution is changed so that the probability of the vicinity of the target position decreases as the timing at the time of impact shifts from the best timing. Speaking of the above example, if the above is the best timing, if a deviation occurs, for example, only 4 out of 10 balls are somewhere near the target position, and 3 balls are outside the target position. It is an image that the two spheres are scattered and reach somewhere in the outer region near the target position, and the one sphere is further somewhere in the outer region near the target position.

  Thereafter, the character acts on the ball, that is, the golfer swings and hits the club against the ball. After the golfer swings and the club hits the ball, a command to start moving the ball is issued, and the ball toward the reaching position is controlled in the game space.

According to the above configuration, since the reach range of the ball with respect to the target position is set in the game space, the player looks at this reach range, and the golfer's shot that he / she will operate from now reaches where. You can get a good idea of what. Also, since the size and shape of the reach range is set (varies) depending on the fairway position, the player moves the target position with the controller (by panning from the camera viewpoint), and determines the reach range he / she wants. You can choose. For example, when the target position is moved near the pin, there is a bunker near the pin, so the reach range of the ball is widened and the ball may be near the pin, but it enters the bunker There are cases where there is a risk. Therefore, if the target position is moved away from the pin (and bunker), although the distance from the pin will be reduced, the reach area of the ball will be narrowed. Conceivable. Therefore, for the player, there is a pleasure of thinking about a strategy of taking a risk and aiming at the buckwheat or avoiding the risk and steadily carving.
Also, in this reachable range, the probability distribution for determining the reach position of the ball is set as described above. When the golfer hits the shot, the arrival position of the ball is determined based on the probability distribution. For this reason, when the golfer hits the best shot, the probability that the ball reaches the vicinity of the target position is high, but the target position is not reached with a probability of 100%. On the other hand, even if the shot shot by the golfer is not the best shot, the ball reaches the target position if the probability that the ball reaches the target position is won. As described above, in the present invention, in principle, the ball flies as instructed by the player to the golfer, but the uncertainty that occurs when golf is played in the real world is also considered at the same time. Therefore, the player can experience a feeling as if he / she is actually playing golf. In other words, the game provider can provide a realistic golf game to the player.

Further, according to the above configuration, since the area of the reach range near the bunker is large from the player's perspective, the player feels that the ball is likely to enter here. In other words, if the bunker or water hazard etc. is located nearby, the golfer's negative psychology that the ball will enter the bunker or water hazard is a bunker or water hazard. It is expressed by the extended reach. In other words, according to the present invention, the uncertain influence of the golfer's psychological factors on the shot can be expressed by the size of the reachable range. Thereby, a realistic golf game can be provided to the player, and the player can experience a feeling as if he / she is actually playing golf.

As described above, since the size and shape of the reach range are set (varies) depending on the position of the fairway, the player moves the target position with the controller (makes panning from the camera viewpoint) You can choose the range you want, so you'll have fun thinking about various strategies, such as how to approach the pin, but here we add elements to further explore that strategy, Game nature improves more. In other words, when a bunker or water hazard is close to the reach, the shape of the reach will be widened toward it, so there is a risk that a ball will enter the bunker or the like compared to the case where such a specification is not adopted. Becomes larger. However, although the risk is high, if the timing at the time of impact when the ball is shot is close to the best timing, the probability that the ball will reach the target position is probabilistic. If the player is confident, it is possible to challenge the pin soba without being bound by the shape of the reach. On the other hand, in order to avoid a risk, a player who is not confident in the operation at the time of impact may move the target position to a place where the outer periphery of the reach does not hit a bunker or the like, and shot on that. Alternatively, it may be assumed that there is a player who is accustomed to the operation at the time of impact but wants to approach the pin steadily without taking risks. In other words, it is possible to realize a game full of diversity that allows various strategies to be considered according to the presence / absence of the controller operation skill, the presence / absence of confidence, and the personality.

More specifically, in this case, when the outer edge of the bunker or water hazard and the target position of the reach range are less than a predetermined distance, the reach range is expanded toward the bunker or water hazard. In other words, by using a threshold value for determining the positional relationship between the bunker, water hazard, etc. and the reach, only when the target position aimed by the player, that is, the target position aimed by the golfer, approaches the bunker, water hazard, etc. The reach is expanded as described above. As described above, the present invention uses the threshold value for determining the positional relationship between the reach of the bunker, water hazard, etc., and the size of the reach that shows the uncertain effect of the golfer's psychological factors on the shot. Therefore, it is possible to adjust reliably.

  In the game program according to claim 2, in the game program according to claim 1, the probability of the moving object increases so that the probability that the object for the moving object reaches the vicinity of the target position increases as the character's ability characteristic increases. Distribution is set. This function is realized in the arrival position setting function.

  The case where this game program is applied to a golf game will be described as an example. In this case, the probability distribution is such that the probability that the ball will reach the vicinity of the target position becomes higher as the ability characteristic of the golfer becomes higher. Is set. In reality, the higher the performance characteristics of the golfer, such as skill and experience, the higher the accuracy of the shot (the less likely the shot will be blurred), so this point is also reflected in the game. Thereby, the player who is playing can make a golfer hit a shot with reality, and can feel as if he is actually playing golf.

  In the game program according to claim 3, in the game program according to claim 1 or 2, the reach range is set so that the reach range with respect to the target position becomes narrower as the ability characteristic of the character becomes higher. . This function is realized in the reach setting function.

  A case where this game program is applied to a golf game will be described as an example. In this case, the reach range is set so that the reach range based on the target position becomes narrower as the performance characteristics of the golfer become higher. . In reality, the higher the performance characteristics of the golfer, such as skill and experience, the higher the accuracy of the shot (the less likely the shot will be blurred), so this point is also reflected in the game. Thereby, a realistic golf game can be provided to the player, and the player can experience a feeling as if he / she is actually playing golf.

In the game program according to claim 4 , in the game program according to any one of claims 1 to 3 , when the outer edge of the predetermined environment object and the target position of the reach range are less than a predetermined distance, The shape of the reachable area is changed so that the extent to which the reachable area expands toward the environmental object increases as the predetermined environment object becomes larger. This function is realized in the reach range changing function.

  The case where this game program is applied to a golf game will be described as an example. In this case, the outer edge of a predetermined environmental object such as a bunker or a water hazard and the target position of the reach range are less than a predetermined distance. In such a case, as the bunker or water hazard increases, the extent to which the reach reaches the bunker or water hazard increases.

  In this case, when the outer edge of the bunker or water hazard and the target position of the reach range are less than a predetermined distance, for example, the arrival of the vicinity of the bunker or water hazard etc. as the bunker or water hazard becomes larger The range also increases. For example, if a bunker, water hazard, etc. become large, the golfer's negative psychology that the ball will enter the bunker, water hazard, etc. also increases, so this psychological factor is near the bunker, water hazard, etc. It is expressed by the size of the reach of the part. In other words, in the present invention, the magnitude of the uncertain influence of the golfer's psychological factors on the shot can be expressed by the size of the reach of a nearby portion such as a bunker or water hazard. Thereby, a realistic golf game can be provided to the player, and the player can experience a feeling as if he / she is actually playing golf.

A game program according to a fifth aspect is the game program according to any one of the first to fourth aspects, wherein the reach range based on the target position is changed based on the environmental characteristics of the environmental object. This function is realized in the reach setting function.

  The case where this game program is applied to a golf game will be described as an example. In this case, the reach range based on the target position is changed based on the environmental characteristics of environmental objects such as fairways and roughs. Is done. For example, when the environmental characteristic of the environmental object is a fairway, the shot accuracy is high, so the reachable range is set small. On the other hand, when the environmental characteristics of the environmental object are rough, the accuracy of the shot deteriorates, so the reachable range is set large. As described above, according to the present invention, the influence that the shot becomes easy or difficult to hit depending on the environment is expressed by the size of the reach corresponding to the environmental characteristics of the environmental object. Thereby, a realistic golf game can be provided to the player, and the player can experience a feeling as if he / she is actually playing golf.

A game device according to a sixth aspect is a game device capable of executing a game in which a moving object is moved to a target position by causing a character to act on the moving object based on an instruction from the player. .

This game apparatus has an environment forming means for placing an environment object forming a game environment in a game space, a character placing means for placing a character in the game space, and a moving object placed in the game space.

The audio data is output as audio from the speaker 13 via the amplifier circuit 14.

[Outline of various processes in game devices]
The game executed in this game device is, for example, a golf game. In this game apparatus, a golf game that moves a ball to a target position by causing a golfer model (hereinafter referred to as a golfer) to hit a ball model (hereinafter referred to as a ball) based on an instruction from the player, It is executed on the computer. FIG. 2 is a functional block diagram for explaining the following functions that play a major role in the present invention.

  The character setting means 50 has a function of setting a golfer.

  In this means, a golfer is set based on an instruction from the player. For example, first, when the player operates the controller 17, an item corresponding to the golfer desired by the player is selected from a list composed of a plurality of golfer names. Then, the golf player, that is, the model for the golf player, and the ability characteristic of the golf player corresponding to this item are recognized. In this way, the model and ability characteristics of the golfer appearing in the game are set. Note that the golfer's model and the golfer's ability characteristics corresponding to each item are defined in advance in the game program and stored in the RAM 12.

  The environment setting means 51 has a function of setting the golf environment of the game space.

  In this means, the environment is set based on an instruction from the player. For example, first, when the player operates the controller 17, an item corresponding to a course desired by the player is selected from a list composed of a plurality of course names. Then, a course, that is, a model for the course, corresponding to this item is recognized. This course model has a plurality of terrain models. Here, models such as green, fairway, rough, bunker, water hazard, tree group, etc. are prepared as models for terrain. Here, the terrain characteristics of each terrain model are recognized. In this way, the model and terrain characteristics of the course adopted in this game are set. The model for the course corresponding to each item and the terrain characteristics corresponding to each course are defined in advance in the game program and stored in the RAM 12.

  The environment forming means 52 has a function of arranging a model for forming a golf environment of the game space in the game space.

  In this means, a model for forming a golf environment of the game space is arranged in the game space. For example, a model for a course, for example, a plurality of terrain models constituting each course is arranged at a predetermined position in the game space. The arrangement position of the model is defined in advance in the game program, and data for arranging the model is stored in the RAM 12.

  The golfer placement means 53 has a function of placing a golfer in the game space.

  With this means, the golfer is placed in the game space. For example, a golfer standing in the field is placed at a predetermined position in the game space. Note that the position of the golfer is defined in advance in the game program, and data for arranging the golfer is stored in the RAM 12.

  The moving body arranging means 54 has a function of arranging the ball in the game space.

  With this means, the ball is placed in the game space. For example, in the case of a tee shot, the ball is placed at a predetermined position in the game space, for example, at a predetermined position in each hole. Further, in the case of a shot other than the tee shot, that is, a shot performed after the tee shot, the ball is arranged at a position where the ball has reached by the previous shot. Note that the placement position of the ball in the case of a tee shot is defined in advance in the game program, and data for placing the ball is stored in the RAM 12.

  The reaching target setting means 55 has a function of setting the target position of the ball in the game space based on an instruction from the player.

  With this means, the target position of the ball is set in the game space based on an instruction from the player. For example, first, when a club is selected by operating the controller 17 by the player, the target position of the ball as an initial condition corresponding to this club is set in the game space. Next, when the player operates the controller 17, the target position of the ball moves in the operation direction of the controller 17 in the game space. In this way, the target position of the ball is set in the game space. Note that data for setting the target position of the ball as an initial condition is defined in advance in the game program for each club and stored in the RAM 12.

  The reach range setting means 56 has a function of setting, in the game space, the reach range that the ball reaches before the club hits the ball with reference to the target position.

  With this means, before the club hits the ball, the reach range where the ball reaches is set in the game space on the basis of the target position. Also, with this means, the reach range is set in the game space so that the reach range based on the target position becomes narrower as the ability characteristic of the golfer becomes higher. Further, in this means, the reach range based on the target position is changed based on the terrain characteristics of the course model, and the reach range is set in the game space.

  For example, when the target position of the ball is set in the game space, the reach range as an initial condition is set in the game space. And the reachable range as an initial condition is changed based on the capability characteristic which a golfer has. Here, the reach range is changed so that the reach range becomes narrower as the performance characteristics of the golfer become higher. In addition, the reach is further changed based on the terrain characteristics of the course model. Here, the reachable range is changed so that the reachable range becomes narrower as the terrain state becomes more stable. In this way, the reach range based on the target position is changed and set in the game space.

  The golfer's ability characteristics include ability characteristics such as the skill and experience of the golfer. The terrain characteristics of the course include terrain characteristics such as fairways and roughs. Data corresponding to each characteristic is defined in advance in the game program and stored in the RAM 12.

  The reach range changing means 57 has a function of changing the shape of the reach range according to the positional relationship between the predetermined terrain model and the reach range.

  In this means, the shape of the reachable range is changed according to the positional relationship between the predetermined terrain model and the reachable range. Specifically, this means determines whether or not the outer edge of the model for a predetermined terrain and the target position of the reach range are less than a predetermined distance. Then, when the outer edge of the predetermined terrain model and the target position of the reachable range are less than the predetermined distance, the reachable range is expanded toward the predetermined terrain model. Further, in this means, when the outer edge of the model for the predetermined terrain and the target position of the reach range are less than the predetermined distance, the reach range is increased as the model for the predetermined terrain increases. The shape of the reach is changed so that the degree of expansion toward the model is increased.

  Here, when the outer edge of a model for a predetermined terrain, for example, a bunker or a water hazard, and the target position of the reach are less than a predetermined distance, the reach reaches the bunker or the water hazard. Enlarged. More specifically, first, when the outer edge of a bunker or water hazard or the like and the target position of the reach range are less than a predetermined distance, the size of the bunker or water hazard or the like is recognized. Then, the size of the reachable range is changed according to the size of the bunker or water hazard. For example, as the size of a bunker, water hazard, or the like increases, the shape of the reach range is changed so that the size of the reach range in the vicinity of the bunker, water hazard, or the like increases.

  The arrival position setting means 58 is based on the distribution of the probability for determining the arrival position where the ball arrives, with the probability decreasing as it moves away from the target position within the arrival range, and based on the state when the club hits the ball The function of setting the arrival position where the ball reaches by changing the probability distribution is provided.

  In this means, the probability distribution for determining the arrival position where the ball arrives is set, and the arrival position where the ball reaches is set based on the probability distribution. For example, first, a probability distribution is set such that the probability decreases with increasing distance from the target position within the reachable range. Then, as the ability characteristic of the golfer increases, the probability distribution is changed so that the probability that the ball reaches the vicinity of the target position increases. Then, the probability distribution is changed based on the state when the club hits the ball. Based on this probability distribution, the arrival position where the ball reaches is set within the arrival range.

  Here, the state when the club hits the ball is set using a gauge for setting the power and timing of the shot. For example, when a first input from the controller 17 is received to instruct the golfer to start acting on the ball, that is, to start a shot, the cursor starts to move on the gauge. When the second input from the controller 17 is accepted while the cursor is moving on the gauge, the cursor is stopped and the shot power is set. Then, the cursor starts moving in the direction opposite to the moving direction. If the third input from the controller 17 is accepted while the cursor is moving on the gauge, the cursor is stopped and the shot timing is set. In this way, the state when the club hits the ball, that is, the power and timing of the shot is set.

  The moving body control means 59 has a function of issuing a command for starting the movement of the ball after the club hits the ball, and controlling the ball heading to the reaching position in the game space.

  In this means, after the golfer swings and the club hits the ball, a command to start the movement of the ball is issued, and the ball toward the reaching position is controlled in the game space. For example, after the golfer hits the ball, the trajectory of the ball is calculated based on information when the club hits the ball, the arrangement position of the ball, the arrival position of the ball, and the like. Here, the trajectory of the ball is defined based on the trajectory equation. For example, by using the information when the club hits the ball, the arrangement position of the ball, the arrival position of the ball, and the like as initial conditions of the trajectory equation, various coefficients of the trajectory equation for defining the trajectory of the ball are: Derived. Then, by substituting the coefficient derived here into the trajectory equation, the trajectory in which the ball released by the golfer moves in the game space is determined.

  The display means 60 has a function of displaying characters and objects on the television monitor 20.

  With this means, a golfer model, a ball model, and a terrain model arranged in the game space are displayed on the television monitor 20. For example, a virtual camera is arranged in the game space, and a golfer model, a ball model, and a terrain model are photographed by the virtual camera, and each model is displayed on the television monitor 20. .

[Outline of uncertainty reflecting system in golf game]
Next, specific contents of the uncertainty reflecting system in the golf game will be described. FIG. 17 is a flowchart for explaining the system in the golf game.

  First, when the game apparatus is turned on and the game apparatus is activated, a game program for a golf game is loaded from the recording medium 10 into the RAM 12 and stored. The game program for the golf game includes various basic game data necessary for executing the golf game. This basic game data is loaded and stored in the RAM 12 together with the game program for the golf game (S1).

  For example, the basic game data includes data related to various images for a three-dimensional game space. The data regarding various images for the three-dimensional game space includes, for example, model data for characters, model data for courses, model data for various other objects, and the like. The basic game data includes 3D image data, for example, position coordinate data for placing model data for a 3D game space in the 3D game space GS. The model data includes three-dimensional polygon data. Further, the basic game data includes image data for displaying the model photographed by the virtual camera on the television monitor 20. Further, the basic game data includes various data used in the above system.

  In the following, the term “golfer” may be used to mean “model (data) for golfer”. In addition, the term “ball” may be used to mean “model (data) for a ball”. Furthermore, the term “game space” may be used to mean “virtual game space” that is generally defined on a program.

  Subsequently, the game program for the golf game stored in the RAM 12 is executed by the CPU 7 based on the basic game data (S2). Then, a golf game start-up screen is displayed on the television monitor 20 (not shown). Then, various setting screens for setting the pre-processing of the golf game, for example, the golf game, are displayed on the television monitor 20.

  Here, for example, a golfer desired by the player is selected (S3). More specifically, a golfer list composed of various types of golfers is displayed on the television monitor 20 (not shown). Here, the player operates the controller 17 to select an item corresponding to a desired golfer from the golfer list. Then, the data for the golfer corresponding to the item selected by this operation is recognized by the CPU 7 (S4). Here, for example, the CPU 7 recognizes the golfer's model P1 (IDg) and ability characteristic data ND (IDg) indicating the ability characteristic of the golfer. Here, the symbol “IDg” is a symbol for identifying a golfer, as will be described later. The symbol “P1 (IDg)” is a symbol indicating a golfer's polygon model. The capability characteristic data ND (IDg) takes a value of 1 or more and 10 or less, for example. The larger this value, the higher the golfer's capability. Thus, the golfer is set based on the instruction from the player.

  The ability characteristic data is data for setting the skill, experience, etc. of the golfer. Capability characteristic data is prepared for each capability. In the following, for ease of explanation, the case where the ability characteristic data ND (IDg) is, for example, skill ability data will be described as an example.

  Here, a supplementary explanation of the golfer setting will be given. For example, when the player selects a golfer, the CPU 7 recognizes the golfer identification data IDg stored in the RAM 12 corresponding to the golfer. Then, the golfer is managed by the CPU 7 using the golfer identification data IDg. Further, the golfer's model and the golfer's ability characteristic data ND (IDg) are managed by the CPU 7 using the golfer's identification data IDg. As shown in FIG. 3, a correspondence table showing the correspondence between each of a plurality of golfers (items) constituting the list and the identification data IDg is defined in advance in the game program and stored in the RAM 12. . A correspondence table showing the correspondence between the identification data IDg, the golfer's model, and the golfer's ability characteristic data ND (IDg) is also defined in advance in the game program and stored in the RAM 12.

  Subsequently, a course that the player desires to play is selected (S5). More specifically, a course list composed of various types of courses is displayed on the television monitor 20 (not shown). Here, when the player operates the controller 17, an item corresponding to the desired course is selected from the course list. Then, the course data corresponding to the item selected by this operation is recognized by the CPU 7 (S6). Here, for example, the model data P2 (IDc1, IDc2) for the course and the terrain characteristic data TD (IDc1, IDc2) of the course are recognized by the CPU 7. Here, the symbol “IDc1” is a symbol for identifying a course, as will be described later. The symbol “IDc2” is a symbol for identifying the terrain. The symbol “P2 (IDc1)” is a symbol indicating the polygon model of the course. The terrain characteristic data TD (IDc1, IDc2) takes a value of 1 to 10, for example, and the larger the value, the more stable the terrain is. Thus, the course is set based on the instruction from the player.

  Here, the explanation about the course setting will be supplemented. For example, when a course is selected by the player, the CPU 7 recognizes course identification data IDc1 stored in the RAM 12 corresponding to the course. Then, the CPU 7 manages the course model and the terrain characteristics TD (IDc1, IDc2) of the course using the identification data IDc1 for the course. The course model has a plurality of terrain models. The terrain model includes, for example, a green model, a fairway model, a rough model, a bunker model, a water hazard model, a tree group model, and the like. For example, the “IDc2” value of the green model is “1”, the “IDc2” value of the fairway model is “2”, the “IDc2” value of the rough model is “3”, and the bunker model The value of “IDc2” of the model is set to “4”, the value of “IDc2” of the model for water hazard is “5”, the value of “IDc2” of the model for the tree group is set to “6”, etc. .

  Then, the terrain characteristic data TD (IDc1, IDc2) corresponding to each terrain model is recognized by the CPU 7. As shown in FIG. 4, a correspondence table indicating the correspondence between each of a plurality of courses (items) constituting the list and the identification data IDc1 and IDc2 is defined in advance in the game program and stored in the RAM 12. ing. In addition, a correspondence table showing the correspondence between the identification data IDc1, IDc2, the course model P2 (IDc1, IDc2) and the course terrain characteristic data TD (IDc1, IDc2) is also defined in advance in the game program. Stored in the RAM 12.

  Hereinafter, the term “course” may be used to mean “model (data) for course”. In addition, the term “terrain” is sometimes used in the sense of “model (data) for terrain”. In addition, the term “terrain characteristics” may be used to mean “terrain characteristics data”.

  When various settings of the golf game are completed, an instruction to start the golf game is issued from the CPU 7. Then, the course is arranged in the game space GS (S7). For example, a course model, for example, a plurality of terrain models P2 (IDc1, IDc2) constituting the course are arranged at predetermined positions in the game space GS. More specifically, by causing the CPU 7 to recognize position coordinate data for defining each of a plurality of terrain models, a plurality of terrain models P2 (IDc1, IDc2) included in the course model are obtained. Are arranged in the game space GS. Then, the course 100 composed of a plurality of terrains is displayed on the television monitor 20 using the image data (see FIG. 5).

  Subsequently, a golfer standing in the field is placed in the game space GS (S8). For example, a golfer model P1 (IDg) is arranged at a predetermined position in the game space GS. More specifically, by causing the CPU 7 to recognize position coordinate data for defining the position of the golfer model P1 (IDg), the golfer model P1 (IDg) is set at a predetermined position in the game space GS. Placed in. Then, the golfer is displayed on the television monitor 20 using the image data. For example, when a golfer shoots a tee shot, a golfer who takes an address posture on the tee ground is displayed on the television monitor 20. Further, when the golfer releases a shot after the second shot, the golfer 101 taking the address posture in the vicinity of the ball on the course is displayed on the television monitor 20 (see FIG. 5).

  Subsequently, the ball is placed in the game space GS (S9). For example, the ball model P3 is arranged at a predetermined position in the vicinity of the golfer. More specifically, by causing the CPU 7 to recognize position coordinate data for defining the position of the ball model P3, the ball model P3 is placed at a predetermined position in the vicinity of the golfer taking the address posture. Placed. For example, in the case of a tee shot, a ball is displayed on the television monitor 20 at a predetermined position in the game space GS, for example, at a predetermined position in each hole. In the case of a shot other than the tee shot, that is, a shot performed after the tee shot, the ball 102 is displayed on the television monitor 20 at the position where the ball has reached by the previous shot (see FIG. 5).

  In addition, the arrangement position of the ball at the time of the tee shot in each course is defined in advance in the game program, and data for arranging the ball, for example, position coordinate data is stored in the RAM 12.

  Here, the display of characters and objects arranged in the game space GS, for example, the display of the model P2 (IDc1, IDc2) for the course, the model P1 (IDg) for the golfer, the model P3 for the ball, etc. I will supplement the explanation.

  In order to display the above model on the television monitor 20, as shown in FIG. 6, first, a virtual camera Pc for photographing the model is arranged in the game space GS. When the game space GS is photographed by the virtual camera Pc, an image inside the viewing angle of the virtual camera Pc is displayed on the television monitor 20. Specifically, the inside of the viewing angle of the virtual camera Pc shown here corresponds to the inside of the view frustum region (view frustum) that is a subject to be captured by the virtual camera Pc. For this reason, the CPU 7 is caused to execute a process of projecting the model located inside the viewing frustum region (view frustum) onto the two-dimensional plane on the camera side, that is, the surface (upper surface) on the short side of the viewing frustum. Thus, the model after projection is displayed on the television monitor 20 using the image data.

  Note that the data for defining the view frustum is previously defined in the game program and stored in the RAM 12. The data for defining the viewing frustum includes, for example, position coordinate data for arranging the virtual camera Pc, angle data for defining the viewing angle (view angle) of the virtual camera Pc, and the short side of the viewing frustum Position coordinate data for defining the surface S1 on the side and the surface S2 on the long side, position coordinate data for the gazing point for setting the line-of-sight direction, and the like.

  Here, when a movement command for moving the virtual camera Pc is issued from the CPU 7, the position coordinate data of the virtual camera Pc after the movement is recognized by the CPU 7. For example, when the player operates the controller 17 to move the virtual camera Pc, or when the movement of the virtual camera Pc is instructed based on an automatic control program (AI program, Artificial Intelligence Program), etc. Is issued from the CPU 7. Then, the position coordinate data of the virtual camera Pc is changed by the CPU 7, and the virtual camera Pc is arranged at the position indicated by the changed position coordinate data. In this way, when the virtual camera Pc is moved and the game space GS is photographed by the virtual camera Pc, characters, objects, etc. inside the viewing angle of the virtual camera Pc after moving (inside the viewing frustum) It is displayed on the television monitor 20.

  Subsequently, when the player operates the controller 17, a club used by the golfer is selected (S10). Then, the CPU 7 recognizes information data corresponding to this club. This information data is defined in advance in the game program for each club and is stored in the RAM 12. Based on this information data, the target position MPo of the ball as an initial condition is set in the game space GS (see S11 and FIG. 7).

  The target position MPo of the ball set here corresponds to an ideal position where the ball reaches when the ball is hit back by the selected club. That is, the target position MPo of the ball as an initial condition corresponds to the position where the ball reaches when the center of the ball is met by the club with the optimal power and the optimal timing. The direction in which the ball flies is set in a direction from the ball placement position to the cup position.

  For example, the information data includes ball discharge speed data and ball discharge angle data when the club hits the ball in an ideal state, and these data are recognized by the CPU 7. Further, rotation data indicating the amount of rotation of the ball is set by the CPU 7. For example, a predetermined rotation amount value is read from the RAM 12, and the predetermined value is recognized by the CPU 7 as a rotation data value. Here, by using these data as initial conditions, the CPU 7 derives various coefficients for uniquely specifying the trajectory equation. Then, based on the trajectory equation to which the coefficient derived here is applied, the position coordinate data indicating the ideal position where the ball reaches when the selected club is used is calculated by the CPU 7. This position coordinate data is recognized by the CPU 7 as position coordinate data indicating the target position MPo of the ball as an initial condition. In this way, the target position MPo of the ball as an initial condition is set in the game space GS.

  Here, an example in which the target position MPo of the ball as an initial condition is set based on the trajectory equation is shown, but it corresponds to an ideal position where the ball reaches when the ball is hit with each club Position coordinate data to be prepared may be prepared in advance in the game program and stored in the RAM 12. Further, flight distance data for setting an ideal reaching position of the ball may be prepared in advance in the game program and stored in the RAM 12. In this case, the target position MPo of the ball as an initial condition is set at the position indicated by the flight distance data with reference to the arrangement position of the ball.

  Subsequently, the reach range TRo as an initial condition is set in the game space GS with reference to the target position MPo of the ball (see S12, FIG. 7). Here, the reach range TRo is formed in a circular shape. In the reach range TRo, the target position MPo of the ball is set at the center of the circle, and the circle radius Ro is set to a predetermined value. Here, for example, 5.0 (m) is used as the value of the radius Ro of the circle.

  The reach range TRo is changed based on the ability characteristics of the golfer. Here, the reach range TR is set so that the area (size) of the reach range TR becomes smaller as the performance characteristics of the golfer become higher (see FIG. 7B). For example, as shown in FIG. 8, the first setting coefficient α1 for setting the size of the reach range TR is set. For example, the first setting coefficient α1 decreases as the value of the ability characteristic data ND (IDg) such as the skill and experience of the golfer increases. The first setting coefficient α1 is set to a value of “1.0” or less. By causing the CPU 7 to execute a process (R1 = Ro × α1) for multiplying the first setting coefficient α1 by a reference length for defining the size of the reachable range TR, for example, the radius Ro, the reachable range TR is reset. Is done.

  Further, the reach range TR is further changed based on the terrain characteristic data TD (IDc1, IDc2) of the model for the course (see FIG. 7C). Here, the reach range TR is set so that the area (size) of the reach range TR becomes smaller as the terrain state becomes stable. For example, as shown in FIG. 9, the second setting coefficient α2 for changing the size of the reach range TR is set. For example, as shown in FIG. 9, the second setting coefficient α2 decreases as the value indicating the terrain characteristic data TD (IDc1, IDc2) such as fairway or rough increases. As an example, FIG. 9 shows the terrain characteristic data TD (1, IDc2) when the a course is selected. The second setting coefficient α2 is set to a value of “1.0” or less. Here, the larger the value of the terrain characteristic data TD (1, IDc2), the more stable the terrain state is. When the second setting coefficient α2 is set in this way, the second setting coefficient α2 is multiplied by a reference length for defining the size of the reachable range TR, for example, the radius R1 (= Ro × α1). The reachable range TR is reset by causing the CPU 7 to execute the process (R2 = R1 × α2). Here, the radius R1 multiplied by the second setting coefficient α2 is a radius changed by the first setting coefficient α1.

  In this way, when the target position MP and the reach range TR of the ball are set in the game space GS (S11, S12), the positional relationship between the reach range TR and a predetermined terrain model P2 (IDc1, IDc2). Is determined by the CPU 7. For example, a predetermined terrain model P2 (IDc1, IDc2), for example, an outer edge such as a bunker (IDc2 = 4) or a water hazard (IDc2 = 5), and the target position MP of the reach range TR are less than a predetermined distance. Whether or not there is is determined by the CPU 7 (S13).

  In order to describe this determination process more specifically, first, a game space GS is defined. Here, the ground plane of the game space GS is defined by the X axis and the Y axis. The origin, X-axis direction, and Y-axis direction are defined in advance in the game program. Here, the Z-axis direction is set to the height direction with respect to the ground plane. In the following, for ease of explanation, the case where the model P2 (IDc1, IDc2) for predetermined terrain is the model P2 (IDc1, 4) for bunker will be described as an example.

  Next, as shown in FIG. 10, a process of projecting a predetermined terrain model P2 (IDc1, IDc2), for example, a bunker model P2 (IDc1, 4) arranged in the game space GS onto the XY plane. , Executed by the CPU 7. Then, the position coordinate data of a plurality of points on the boundary (outer edge) of the bunker model P2 (IDc1, 4) projected on the XY plane is recognized by the CPU 7. A plurality of points on the boundary are recognized by the CPU 7 with a resolution of 10 cm (X-axis direction) × 10 cm (Y-axis direction). In FIG. 10, in order to make the drawing easier to see, not only all points on the boundary but only six points on the reach range TR side at a resolution lower than the resolution set above are indicated by black circles.

  Further, the CPU 7 searches for the point closest to the target position MP of the ball on the boundary of the bunker model P2 (IDc1, 4) projected on the XY plane. For example, based on the position coordinate data indicating the target position MP of the ball and the position coordinate data of each of a plurality of points on the boundary of the bunker model P2 (IDc1, 4), the target position MP of the ball and the bunker The CPU 7 executes processing for calculating the distance to each of a plurality of points on the boundary of the model P2 (IDc1, 4). Based on the calculated distance between the two points, the position coordinate data of the point closest to the target position MP of the ball is recognized by the CPU 7. Thereby, the point closest to the target position MP of the ball on the boundary of the bunker model P2 (IDc1, 4) is specified. For example, in FIG. 10, the point closest to the target position MP of the ball is indicated by the symbol “CP”.

  Then, the CPU 7 determines whether the distance between the target position MP of the ball and the point CP closest to the target position MP of the ball, that is, the shortest distance SL between the two points is less than a predetermined distance. For example, when the unit system of the game space GS is the same unit system as the real space, the outer edge of a predetermined terrain model, for example, the outer edge of the bunker model P2 (IDc1, 4), the target position MP of the ball, The CPU 7 determines whether or not the shortest distance SL is less than 10 m.

  When the shortest distance SL between the outer edge of the bunker model P2 (IDc1, 4) and the target position MP of the reach range TR is less than a predetermined distance (Yes in S13), the bunker model P2 (IDc1) , 4) is recognized by the CPU 7. For example, when the shortest distance SL between the outer edge of the bunker model P2 (IDc1, 4) and the target position MP of the ball is less than 10 m, the boundary of the bunker model P2 (IDc1, 4) on the XY plane Using the position coordinate data of each of the plurality of points above, the internal area (= ΣΔSn) of the bunker model P2 (IDc1, 4) is calculated by the CPU 7 and recognized by the CPU 7. For example, as shown in FIG. 11, “ΔSn” is a band-shaped partial area defined by two adjacent points on the boundary. Then, by adding the adjacent partial areas (= ΣΔSn), the internal area of the bunker model P2 (IDc1, 4) is calculated. In FIG. 11, only three band-like partial areas ΔSn, ΔSn + 1, and ΔSn + 2 are shown for easy viewing of the drawing.

  In this way, when the size (area) of the bunker model P2 (IDc1, 4) is recognized by the CPU 7, the reach TR is changed to the bunker model P2 (in accordance with the size of the model). It is enlarged toward IDc1, 4) (S14). For example, as shown in FIG. 10, as the size of the bunker model P2 (IDc1, 4) increases, the shape of the arrival range TR is such that the arrival range TR in the vicinity of the bunker increases. Be changed.

  Here, an example when changing the shape of the reach range TR will be described. For example, first, the CPU 7 searches for the point CP closest to the target position MP of the ball on the boundary of the bunker model P2 (IDc1, 4) projected on the XY plane as described above. For example, based on the position coordinate data indicating the target position MP of the ball and the position coordinate data of each of a plurality of points on the boundary of the bunker model P2 (IDc1, 4), the target position MP of the ball and the bunker The CPU 7 executes processing for calculating the distance to each of a plurality of points on the boundary of the model P2 (IDc1, 4). Based on the calculated distance between the two points, the CPU 7 recognizes the position coordinate data of the point CP closest to the target position MP of the ball. Thus, the point CP closest to the target position MP of the ball on the boundary of the bunker model P2 (IDc1, 4) is specified.

  Then, as shown in FIG. 12, two basic figures are set on the XY plane with reference to the target position MP of the ball and the position CP on the outer edge closest to the target position MP of the ball. For example, the CPU 7 generates equations for two circles (first circle CL1 and second circle CL2) centered on the target position MP of the ball and the position CP on the outer edge closest to the target position MP of the ball. Is done. Thereby, the first circle CL1 and the second circle CL2 are set on the XY plane.

  The center of the first circle CL1 is set to the target position MP of the ball. Further, the radius of the first circle CL1 is set to the same value as the radius R2 of the above reach range TR. The center of the second circle CL2 is set at a position CP closest to the target position MP of the ball at the outer edge of the bunker model P2 (IDc1, 4). The radius of the second circle CL2 is set to a predetermined value according to the size of the bunker model P2 (IDc1, 4) on the XY plane. For example, the radius of the second circle CL2 is set so that the value of the radius of the second circle CL2 increases as the size of the bunker model P2 (IDc1, 4) increases. The correspondence relationship between the size of the bunker model P2 (IDc1, 4) on the XY plane and the radius of the second circle CL2 is defined in advance in the game program and stored in the RAM 12.

  In this way, when two basic figures, for example, the first circle CL1 and the second circle CL2 are set, the boundary of the reach range TR is formed using the first circle CL1 and the second circle CL2. Processing to be executed is executed by the CPU 7. For example, when two circles intersect, a process of smoothing the vicinity of the two intersections is executed by the CPU 7 (see the thick broken line in FIG. 12A). Further, when the two circles do not intersect, the process of smoothing the line connecting the two circles so that the line connecting the two circles is concave in the direction of the straight line connecting the centers of the two circles is performed by the CPU 7. (See the thick broken line in FIG. 12B). Thereby, two circles are converted into one figure. That is, two closed curves (two circles) existing on the XY plane are converted into one closed curve (a bowl-shaped curve). By causing the CPU 7 to execute such processing, the shape of the reachable range TR is changed.

  Here, since the radius of the second circle CL2 increases as the size of the bunker model P2 (IDc1, 4) increases, the bunker increases when the size of the bunker model P2 (IDc1, 4) increases. The reach range TR in the vicinity of is also increased. In this way, the reach range TR based on the target position MP is changed according to various conditions and set in the game space GS. Each data used here is defined in advance in the game program and is stored in the RAM 12. A program used for smoothing is included in the game program and stored in the RAM 12.

  When the shortest distance SL between the outer edge of the bunker model P2 (IDc1, 4) and the target position MP of the reach range TR is equal to or greater than a predetermined distance (No in S13), the size of the reach range Is not changed, and the process of step 15 (S15) to be described later is executed by the CPU 7.

  Subsequently, when the reach range TR is set (S14), the CPU 7 executes a process of setting the probability distribution for determining the arrival position where the ball arrives within the reach range TR (S15). For example, first, a probability distribution (basic distribution of probabilities) as an initial condition in which the probability K decreases as it moves away from the target position MP of the ball within the reach range TR is read from the RAM 12 and recognized by the CPU 7. (See FIG. 13). Also, the golfer's ability characteristic data ND (IDg) stored in the RAM 12 is recognized by the CPU 7. Then, based on the golfer's ability characteristic data ND (IDg), the CPU 7 executes a process for changing the basic distribution of the probability. For example, the basic distribution of the probabilities is changed by the CPU 7 so that the probability K that the ball reaches the vicinity of the target position MP increases as the golfer's ability characteristic data ND (IDg) increases.

  In FIG. 13A, the horizontal axis indicates region number data NR for distinguishing a plurality of partitioned regions inside the reachable range TR. The vertical axis indicates the probability of each segmented area. FIG. 13B shows an example of each divided region formed inside the reachable range TR. Further, the numbers shown in FIG. 13B are numbers corresponding to the region number data NR.

  For example, as shown in FIG. 14, a first correction coefficient β1 for correcting the probability distribution is set. In FIG. 14, the first correction coefficient β1 is set for each division so that the probability K near the target position MP of the ball increases as the value of the ability characteristic data ND (IDg) such as the skill and experience of the golfer increases. Set to area. Then, by causing the CPU 7 to execute a process of multiplying the first correction coefficient β1 of each segmented region by the probability K (NR) of the segmented region near the target position MP of the ball, the basic distribution of the probability is changed. Is done. For example, the CPU 7 executes a process (K ′ (1) = K (1) × β1) for multiplying the first modification coefficient β1 of each divided region by the probability K (1) of the divided region whose probability is to be changed. The Then, a process (K ′ (NR) = K (NR) − | K ′ (1) for adjusting the probability (= | K ′ (1) −K (1) |) increased or decreased according to this processing result with another probability. ) -K (1) | / 4; NR = 2, 3, 4, 5) is executed by the CPU 7. In this way, the basic distribution of the probability is changed. Then, the changed probability distribution is recognized by the CPU 7 and stored in the RAM 12. The divided areas are areas obtained by dividing the area between the target position MP of the ball and the boundary of the reach range TR into a plurality of areas on the basis of the target position MP of the ball.

  As described above, when the probability distribution is set, by causing the CPU 7 to recognize the region number data NR, the probability K (NR) of the segmented region corresponding to the region number data NR is determined. That is, the process of setting the probability distribution includes a process of assigning a probability to each segmented area. Therefore, by setting the probability distribution, the probability K (NR) is set for each segmented region inside the reachable range TR. In this way, the probability distribution is set inside the reachable range TR.

  When the target position MP, the reach range TR, and the probability distribution are set as described above, the position coordinate data of the target position MP on the XY plane and the position on the boundary of the reach range TR on the XY plane The CPU 7 executes a process of projecting the coordinate data onto the terrain model. For example, by causing the CPU 7 to recognize the Z coordinate data of the terrain model P2 (IDc1, IDc2) at the target position MP of the ball on the XY plane as the Z coordinate data of the target position MP of the ball, The target position MP of the ball is projected onto the terrain model. Further, the CPU 7 uses the Z coordinate data of the terrain model P2 (IDc1, IDc2) at the position of each point on the boundary of the reach range TR on the XY plane as the Z coordinate data of each point on the boundary of the reach range TR. As a result, the reach TR on the XY plane is projected onto the terrain model.

  As described above, in the present embodiment, first, the target position MP of the ball and the arrival position of the ball are evaluated on the two-dimensional plane (XY plane), and then the target position MP of the ball and the arrival position of the ball after the evaluation are evaluated. It is reflected on the three-dimensional space (XYZ space). As a result, main calculations can be processed not in the three-dimensional space but in the two-dimensional plane, so that the memory capacity and the calculation load on the CPU 7 can be greatly reduced.

  Subsequently, as shown in FIG. 5, based on the position coordinate data of the target position MP of the ball projected onto the terrain model, an informing element 200 for informing the target position MP of the ball, for example, a triangle symbol Is displayed on the television monitor 20 using the image data (S16). Further, as shown in FIG. 5, a boundary line for informing the arrival range TR, for example, the arrival range TR, based on the position coordinate data of each point on the boundary of the arrival range TR projected on the terrain model. 201 is displayed on the television monitor 20 using the image data (S17). In this way, the point where the ball is carried is notified by the triangle symbol 200, and the range where the ball can reach when aiming at this point, that is, the reach range TR of the ball is the boundary line 201 of the reach range TR. Will be informed.

  FIG. 5 shows an example in which the shape of the reach range TR is a circle. However, the shape of the reach range TR is changed according to the positional relationship between the target position of the ball and the terrain model. In such a case, the changed shape, for example, a trough-shaped reach range TR is displayed on the television monitor 20 (see FIG. 12).

  Thus, when the player operates the controller 17 in a state where the target position MP and the reach range TR of the ball are displayed on the television monitor 20, the target position MP of the ball moves. For example, when the player operates the controller 17, a movement command for moving the target position MP of the ball is issued from the CPU 7 based on an input signal from the controller 17. Then, the position coordinate data of the target position MP of the ball on the XY plane is changed by the CPU 7 in accordance with the operation amount of the controller 17. Then, as described above, the target position MP of the ball on the XY plane indicated by the changed position coordinate data is projected onto the terrain model. Then, a triangle symbol (notifier) is displayed on the television monitor 20 at the target position MP projected onto the terrain model. As described above, when the player operates the controller 17, a state in which the ball target position MP, 200 moves is displayed on the television monitor 20.

  Here, when the target position MP, 200 of the ball moves, the reach ranges TR, 201 also move in conjunction with the movement of the target position MP, 200. For example, when the position coordinate data of the target position MP of the ball on the XY plane is changed by the CPU 7, the reach range TR with reference to the target position MP indicated by the changed position coordinate data becomes XY as described above. The range TR is set on the plane, and the range TR on the XY plane is projected onto the terrain model. Then, 201 indicating the reach TR based on the target position MP after the movement is displayed on the television monitor 20. Note that the size and shape of the reach ranges TR and 201 vary according to the target positions MP and 200. Thus, when the target position MP, 200 of the ball moves, a state in which the reach range TR, 201 of the ball moves in conjunction with the movement of the target position MP, 200 of the ball is displayed on the television monitor 20. . The movement of the target position MP of the ball and the reach range TR of the ball is realized by repeatedly executing the processing from step 11 (S11) to step 17 (S17).

  Subsequently, when the target position MP of the ball desired by the player is determined, the position at which the club is applied to the ball, that is, the position of the hit point of the club with respect to the ball is set (S18). Here, the hitting point 301 of the ball is set using the hitting ball 300 as shown in FIG. In the initial condition, a circle symbol indicating the hit point 301 is displayed at the center of the hit point ball 300. In this state, the CPU 7 recognizes rotation data indicating the rotation amount when the hit point is the center of the ball.

  In this state, when the player operates the controller 17, the hit point 301 (circle symbol) moves in the operation direction of the controller 17. If the operation of the controller 17 is stopped when the hit point 301 is located at a position desired by the player, the movement of the hit point 301 is also stopped. Then, the rotation data indicating the rotation amount when the club hits the ball at the hitting point 301 is recognized by the CPU 7. As described above, by setting the hit point 301, the CPU 7 sets the amount of rotation given to the ball, that is, rotation data.

  For example, when the hit point 301 is positioned on the right side of the hit point ball with respect to the center of the hit point ball 300, the ball rotates counterclockwise when the three-dimensional model ball is viewed from above. On the other hand, when the hit point 301 is positioned on the left side of the hit point ball with respect to the center of the hit point ball 300, the ball rotates clockwise as viewed from above. Thus, the amount of rotation when the ball rotates is defined using the rotation data.

  Note that the correspondence between the position coordinate data of the hit point 301 and the rotation data is defined in advance in the game program and stored in the RAM 12. That is, when the hit point position is determined, rotation data corresponding to the hit point position is read from the RAM 12 and recognized by the CPU 7.

  Subsequently, using the gauge 400 as shown in FIG. 5, the power applied to the ball and the timing for meeting the ball are set (S19). For example, when the player operates the controller 17 to instruct the golfer to start a shot, the CPU 7 recognizes the first input signal from the controller 17. Then, based on the first input signal, a state in which the cursor 401 moves on the gauge is displayed on the television monitor 20 as shown in FIG. At this time, the action of the golfer taking back is displayed on the television monitor 20 (not shown).

  When the player operates the controller 17 at a desired timing in order to set the shot power, the CPU 7 recognizes the second input signal from the controller 17. Then, based on the second input signal, the cursor 401 temporarily stops and the shot power is set. Then, as shown in FIG. 15B, a state in which the cursor 401 moves in the direction opposite to the moving direction on the gauge is displayed on the television monitor 20. At this time, the movement of the golfer swinging is displayed on the television monitor 20 (not shown).

  When the player operates the controller 17 at a desired timing to set the shot timing, the CPU 7 recognizes the third input signal from the controller 17. Then, based on the third input signal, as shown in FIG. 15C, the cursor 401 is stopped and the shot timing is set. Then, a state in which the golfer meets the ball and performs a follow swing is displayed on the television monitor 20 (not shown).

  As shown in FIG. 15, the gauge is provided with a first position D1 where an optimum power is set and a second position D2 where an optimum timing is set. Here, the CPU 7 recognizes the first displacement amount Z1 from the first position D1 of the gauge and the second displacement amount Z2 from the second position D2 of the gauge. Here, the sign of the second displacement amount Z2 on the left side of the second position D2 in FIG. 15 is defined as plus, and the sign of the second displacement amount Z2 on the right side of the second position D2 in FIG. 15 is defined as minus.

  Then, the position coordinate data of the target position MP of the ball is reset based on the first deviation amount Z1 and the second deviation amount Z2 (S20).

  First, the position coordinate data of the target position MP of the ball is reset based on the first deviation amount Z1. For example, when the first deviation amount Z1 is “0”, that is, when the input is executed at the first position D1, the position coordinate data of the target position MP of the ball is re-recognized by the CPU 7. On the other hand, when the first deviation amount Z1 is not “0”, that is, when the input is executed at a position away from the first position D1, the target position of the ball according to the magnitude of the value of the first deviation amount Z1. Processing for moving the MP is executed by the CPU 7. Then, the position coordinate data of the target position MP of the ball after movement is re-recognized by the CPU 7 and stored in the RAM 12.

  Next, the position coordinate data of the target position MP of the ball is reset based on the second deviation amount Z2. For example, when the second deviation amount Z2 is “0”, that is, when the input is executed at the second position D2, the position coordinate data of the target position MP of the ball stored in the RAM 12 is re-recognized by the CPU 7. . Here, the position coordinate data of the target position MP of the ball recognized by the CPU 7 is position coordinate data of the target position MP of the ball moved in accordance with the magnitude of the value of the first deviation amount Z1. On the other hand, when the second shift amount is not “0”, that is, when input is performed at a position away from the second position D2, the position of the cursor 401 with respect to the second position D2 and the second shift amount Z2 The CPU 7 executes a process of moving the target position MP of the ball according to the magnitude of the value. For example, the CPU 7 executes a process of changing the target position MP of the ball so that the target position MP of the ball moves to the right side as the magnitude of the second deviation amount Z2 on the right side of the second position D2 increases. The Further, the CPU 7 executes a process of changing the target position MP of the ball so that the target position MP of the ball moves to the left side as the second deviation amount Z2 on the left side of the second position D2 increases. The Then, the position coordinate data of the target position MP of the ball after movement is re-recognized by the CPU 7 and stored in the RAM 12.

  Then, based on the position coordinate data indicating the target position MP of the ball moved based on the first deviation amount Z1 and the second deviation amount Z2, the reach range TR based on the target position MP of the ball is a game space. Reset to GS. Here, with the straight line connecting the ball placement position and the cup position as a reference, the right side of this straight line is expressed in terms of “right”, and the left side of this straight line is expressed in terms of “left side”. .

  Further, based on the second deviation amount Z2, the probability distribution within the reach range TR is reset (S21). For example, when the second deviation amount Z2 is “0”, that is, when an input is executed at the second position D2, the CPU 7 recognizes the current probability distribution as the final probability distribution. On the other hand, when the second displacement amount Z2 is not “0”, that is, when an input is executed at a position away from the second position D2, the second displacement amount Z2 is stored in the RAM 12 according to the magnitude of the value of the second displacement amount Z2. The CPU 7 executes processing for changing the distribution of the probabilities. For example, the probability distribution is changed so that the probability of the target position MP decreases as the second deviation amount Z2 increases. When the probability distribution is changed in this way, the changed probability distribution is recognized by the CPU 7 as the final probability distribution.

  Here, for example, as shown in FIG. 16, a second correction coefficient β2 for re-correcting the probability distribution is set. In FIG. 16, the second correction coefficient β2 is set in each segmented region so that the probability of the target position MP decreases as the second shift amount Z2 that is the timing shift increases. Then, by causing the CPU 7 to execute a process of multiplying the second correction coefficient β2 of each divided region by the probability K (NR) of the divided region near the target position MP of the ball, the first correction coefficient β1 is used. The distribution of the changed probability is changed. For example, the CPU 7 performs a process (K ″ (1) = K ′ (1) × β2) for multiplying the probability K ′ (1) of the divided region whose probability is to be changed by the second correction coefficient β2 of each divided region by the CPU 7. Then, the process of adjusting the probability (= | K ″ (1) −K ′ (1) |) increased or decreased according to the result of this process with another probability (K ″ (NR) = K ′ (NR) − | K ″ (1) −K ′ (1) | / 4; NR = 2, 3, 4, 5) is executed by the CPU 7. In this way, the basic distribution of the probability is changed. Then, the changed probability distribution is recognized by the CPU 7 and stored in the RAM 12. In this way, the final probability distribution is set within the reach TR.

  Subsequently, the arrival position of the ball is determined based on the probability distribution (S22). For example, as shown in FIG. 13, when each probability constituting the probability distribution is “k1 (%), k2 (%), k3 (%), k4 (%), k5 (%)”, These probabilities satisfy the relationship of “k1 + k2 + k3 + k4 + k5 = 100 (%)”. Here, for easy explanation, each probability is “45% (= k1), 25% (= k2), 15% (= k3), 10% (= k4), 5% (= k5)”. The case will be described as an example.

  For example, when the game machine 1 is turned on, the CPU 7 executes a process of setting the probability count parameter i to zero (i = 0). Then, the CPU 7 executes a process of incrementing the probability count parameter i by 1 every predetermined time, for example, every one frame (ex. 1/60 seconds). The value of the probability count parameter i is stored in the RAM 12. When the final probability distribution is recognized by the CPU 7, the value of the probability count parameter i is stored in the RAM 12. Then, the CPU 11 recognizes the last two digits j of the probability count parameter i.

  Then, the CPU 7 determines whether or not the last two digits value j of the probability count parameter i is 0 or more and 5 or less. If the value j is greater than or equal to 0 and less than 5 (0 ≦ j <5 (0 ≦ j <k5)), the region number data NR (5) of the partitioned region with a probability of 5% (the partitioned region with the probability k5 (%)) ) Is recognized by the CPU 7. As a result, a partitioned region having a probability of 5% (a partitioned region having a probability k5 (%)) is specified. Then, the position coordinate data inside this segmented area is randomly generated by the CPU 7. The position coordinate data is recognized by the CPU 7 as position coordinate data of the arrival position of the ball.

  When the value j is 5 or more and less than 15 (5 ≦ j <15 (k5 ≦ j <k4 + k5)), the region number data NR (4) of the partitioned region with a probability of 10% (the partitioned region with the probability k4 (%)) ) Is recognized by the CPU 7. As a result, a segmented region with a probability of 4% (a segmented region with a probability k4 (%)) is specified. Then, the position coordinate data inside this segmented area is randomly generated by the CPU 7. The position coordinate data is recognized by the CPU 7 as position coordinate data of the arrival position of the ball.

  When the value j is 15 or more and less than 30 (15 ≦ j <30 (k4 + k5 ≦ j <k3 + k4 + k5)), the region number data NR (3 of the segmented region with the probability of 15% (the segmented region with the probability k3 (%)) ) Is recognized by the CPU 7. As a result, a segmented region with a probability of 15% (a segmented region with a probability k15 (%)) is specified. Then, the position coordinate data inside this segmented area is randomly generated by the CPU 7. The position coordinate data is recognized by the CPU 7 as position coordinate data of the arrival position of the ball.

  When the value j is 30 or more and less than 55 (30 ≦ j <55 (k3 + k4 + k5 ≦ j <k2 + k3 + k4 + k5)), the region number data NR (2) of the partitioned region with a probability of 25% (the partitioned region of probability k2 (%)) As a result, the CPU 7 recognizes a segment area with a probability of 25% (a segment area with a probability k2 (%)), and the position coordinate data inside the segment area is randomly determined by the CPU 7. Then, this position coordinate data is recognized by the CPU 7 as position coordinate data of the arrival position of the ball.

  When the value j is 55 or more and 100 or less (55 ≦ j ≦ 100 (k2 + k3 + k4 + k5 ≦ j ≦ k1 + k2 + k3 + k4 + k5)), the region number data NR (1) of the segmented region with the probability 45% (the segmented region with the probability k1 (%)) ) Is recognized by the CPU 7. As a result, a segmented region having a probability of 45% (a segmented region having a probability k1 (%)) is specified. Then, the position coordinate data inside this segmented area is randomly generated by the CPU 7. The position coordinate data is recognized by the CPU 7 as position coordinate data of the arrival position of the ball.

  In this way, the arrival position of the ball is determined based on the probability distribution. Note that the position coordinate data inside each segmented region is generated using a random number generation program. This random number generation program is included in the game program and is stored in the RAM 12.

  Subsequently, when the ball is met by the golfer, a command for starting the movement of the ball is issued from the CPU 7. Then, the ball toward the reaching position is controlled in the game space GS (S23). For example, based on information data when the club hits the ball, rotation data indicating the amount of rotation of the ball, position coordinate data indicating the placement position of the ball, position coordinate data indicating the arrival position of the ball, etc. The CPU 7 derives various coefficients of the orbital equation for prescribing. Then, by causing the CPU 7 to execute a process for substituting the coefficient derived here into the trajectory equation, the trajectory of the ball released by the golfer is set. Then, a state in which the ball moves on the trajectory for a predetermined time, for example, every frame is displayed on the television monitor 20.

  Subsequently, it is determined by the CPU 7 whether or not the ball is cupped in (S24). Then, when the ball is cupped in (Yes in S24), it is determined by the CPU 7 whether or not 18 holes have been completed (S25). Then, when the 18 holes are finished (Yes in S25), the CPU 7 determines whether or not an instruction to finish the game is instructed (S26). When an instruction to end the game is instructed (Yes in S26), the game data is stored in the RAM 12 and recorded from the RAM 12 to the recording medium 10 (S27).

  Here, when the ball is not cupped in (No in S24), the process of step 9 (S9) is re-executed by the CPU 7. On the other hand, when the 18 holes have not been completed (No in S25), the process of Step 9 (S9) is re-executed by the CPU 7. Further, when the instruction to end the game is not instructed (No in S26), that is, when the instruction to restart the game is instructed, the process of step 3 (S3) is re-executed by the CPU 7.

  As described above, in the present embodiment, the ball reach range TR with respect to the target position MP is set in the game space GS, so that the player sees the reach range TR and the golfer he / she will operate from now on. You can make an idea of where the shot will reach. In addition, the probability distribution for determining the arrival position of the ball is set in the arrival range TR as described above. When the golfer hits the shot, the arrival position of the ball is determined based on the probability distribution. For this reason, when the golfer has shot the best shot, the probability that the ball reaches the target position MP and the vicinity of the target position MP is high, but the ball does not necessarily reach the target position MP. If the shot shot by the golfer is not the best shot, the probability that the ball will reach a position distant from the target position MP will be high, but if the ball wins the probability that the ball will reach the target position MP, The target position MP is reached. Thus, in this embodiment, in principle, the player's instruction to the golfer is reflected in the shot, but the uncertainty that occurs when golf is played in the real world can be considered at the same time. it can. Thereby, although the player is playing the golf game, the player can enjoy a feeling as if he / she is actually playing golf. In other words, the game provider can provide a realistic golf game to the player.
