Description

  The present invention relates to a game program, and more particularly to a game program for realizing a game in which a character sequentially moves a plurality of targets in a game space. The present invention also relates to a game apparatus that can execute the game program, and a game control method that is controlled by a computer based on the game program.

  Conventionally, various video games have been proposed. These video games are executed in a game device. For example, a general game device has a monitor, a game device main body separate from the monitor, and an input device such as a controller separate from the game device main body. The controller has a plurality of input buttons.

  For example, a role playing game is known as one of video games realized in such a game device (see Patent Document 1). In this role-playing game, a character (player character) operated by the player moves in the three-dimensional game space while accompanying the other three member characters.

  Further, when the role playing game is being executed, an image that can be seen from the first-person viewpoint or the third-person viewpoint of the player character is displayed on the monitor. Here, the image seen from the first-person viewpoint of the player character corresponds to the image seen from the viewpoint of the player character. Further, an image that can be seen from the first-person viewpoint of the player character is displayed on a main screen corresponding to the entire screen of the monitor. On the other hand, an image that can be seen from the third person viewpoint corresponds to an image that represents a party composed of all characters and the periphery of the party. Further, an image that can be seen from the third person viewpoint is displayed on a sub-screen corresponding to a part of the entire screen of the monitor.

JP-A-10-113466

  In a conventional role playing game, an image that is visible from the first-person viewpoint of the player character is displayed on the main screen. In addition, an image that can be seen from the third person viewpoint is displayed on the sub-screen. In particular, the image that can be seen from the third person viewpoint expresses a party composed of all characters and the periphery of this party.

  For this reason, in the conventional role playing game, the player can grasp the situation of the character (player character) that he / she operates on the main screen, and can grasp the whole party situation including this player character on one sub-screen. From this, it can be understood that the conventional role-playing game is assumed to achieve the objective in the whole party.

  On the other hand, in reality, not only the above type of game (A type game) but also a type of game (B type game) in which one character moves alone in a three-dimensional game space. In the B type game, since there is one character, it is not necessary to grasp the situation of the whole party. For this reason, generally, in the B type game, the sub-screen used in the A type game is not displayed on the monitor. However, in the B type game, it is very difficult to move the player character to the destination without any information. Therefore, some information for guiding the player character to the destination is given to the player. It is necessary to provide it.

  For example, one of the information that has been used conventionally is a radar screen. By displaying the radar screen on the monitor, the player can move the player character to the destination while viewing the radar screen. However, since this form of information provision has been used for quite a long time, there is a problem that the player who receives this information feels monotonous when the game progresses. For this reason, various forms of providing information have been sought by game providers so far, but in reality, it has not been possible to provide a form that satisfies the player.

  The present invention has been made in view of such problems, and an object of the present invention is to realize a game capable of providing information that can improve interest.

A game program according to claim 1 is a program for realizing the following functions in a computer capable of executing a game in which a character sequentially moves a plurality of targets in a game space.
(1) A main screen setting function for setting a main screen, which is a screen for characters, in the image display unit.

( 4 ) A character control function for controlling the character in the game space.
( 5 ) A control time calculation function for calculating the time from when the control start command is issued.
( 6 ) A main image display function for displaying an image of the game space within the viewing angle of the character on the main screen.
( 7 ) A sub-screen setting function for setting a sub-screen that is a screen for the target object and is smaller than the main screen in the main screen in the image display unit.
( 8 ) A sub video display function for displaying the video of the game space including the target object on the sub screen.
( 9 ) A position determination function for determining whether or not the target object is positioned inside the game space within the viewing angle of the character being controlled.
( 10 ) A sub-screen erasing function for erasing a sub-screen for the target object from the image display unit when the position of the target object is located inside the game space within the viewing angle of the character.
( 11) An all-sub-screen erasure determination function for determining whether or not all target object sub-screens have been deleted from the image display unit.
( 12 ) A control time storage function for storing, as a control time, a time at which the character reaches the target object when it is determined by the all sub screen deletion determination function that all the sub screens have been deleted from the image display unit.
(13) A control time display function for displaying the control time on the image display unit.

  Here, a case where this game program is applied to an adventure game will be described as an example. For example, a game in which a character alone moves in the game space and sequentially searches for a plurality of treasures is executed on the computer.

In this game, first, a main screen, which is a character screen, is set in the image display section. Then, the positions of a plurality of treasure objects (target objects) which are the goals aimed by the character are set in the game space. When a character searching for a plurality of treasure objects is operated in the game space, a process for controlling the character is started based on a control start command. Then, the time from when the control start command is issued is calculated. Then, an image of the game space within the character's viewing angle is displayed on the main screen.
Further, the sub screen is set in the image display unit. This sub-screen is a treasure screen, and is set smaller than the main screen inside the main screen. On this sub-screen, a video of the game space including the treasure object is displayed. In this state, it is determined whether or not the treasure object is located inside the game space within the viewing angle of the character being controlled. Then, when the position of the treasure object is located inside the game space within the viewing angle of the character, the treasure sub-screen is deleted from the image display unit. Then, it is determined whether or not all treasure sub-screens have been erased from the image display unit. When it is determined that all the sub screens have been erased from the image display unit, the time when the character reaches the treasure object is stored as the control time. Then, this control time is displayed on the image display unit.

  In this case, the player can grasp an image within the viewing angle of the character, for example, a scene that falls within the viewing angle of the character on the main screen. Further, the player can grasp information related to the treasure object, for example, the scenery in the vicinity of the treasure object on the sub-screen. However, since the information on the sub screen is not the position of the treasure object itself but an image of the peripheral area where the treasure object exists, the player can determine the treasure object based on the information on the sub screen. It is necessary to search for treasure objects while guessing the position. For example, if the scenery in the sub-screen is the coast, you can see that the treasure object is near the sea, so the player first moves towards the sea and then resembles the sub-screen along the overseas We will look for the scenery. Thus, in the invention according to claim 1, by using the sub screen, it is possible to consider the element of estimating the location of the treasure object.

  In addition, the player relies on the information (landscape) on the main screen and the information (landscape) on the sub screen to move the character operated by the player to the position of the treasure object. When the position of the object for use is located inside the game space within the viewing angle of the character, the treasure sub-screen is deleted from the image display unit. That is, in a state where a part of the scenery on the sub-screen reflecting the vicinity of the treasure object is reflected in the scenery on the main screen, this corresponds to the fact that the character has arrived in the vicinity of the target treasure. Also, in this state, the player can recognize the fact by visually recognizing that a part of the main image and the sub screen image indicate the same place. For this reason, there is no point in continuing to display the sub-screen for target search at this time, so the sub-screen is deleted from the image display unit in order to effectively use the area of the main screen. If the player does not notice that the main screen and a part of the sub screen have been shared in common, the deletion of the sub screen informs the player that the object is approaching the treasure object. Become. In other words, when the treasure sub-screen is deleted from the image display unit, the player can recognize that the character operated by the player is located in the vicinity of the treasure object. Thus, the process of deleting the sub screen from the image display unit not only can ensure a large main screen area smoothly, but also gives the player a sense of being close to the target position and informs the information. be able to. Furthermore, since the sub-screens are sequentially erased thereafter, a sense of accomplishment of finding treasure objects one after another can be obtained, so that the effect of attracting the player more strongly into the game is exhibited.

  Thus, in the invention according to claim 1, by using the sub-screen, it is possible to simultaneously realize the fun of guessing and searching for the target and the effect of giving the player a satisfaction of reaching the target and the information notification function. Can do. Thereby, the game provided with the completely different interest from the past can be provided with respect to a user.

Here, the time when the character approaches the last one of the plurality of treasures and the character reaches the treasure object is stored as the control time. This control time corresponds to the time required for the character to search for all treasures. In this way, by storing the control time during the game execution, the player can check his / her own results, that is, the time required to find all treasures every time the game is repeatedly executed. Can do. Thereby, the player comes to the game with a sense of tension so that the control time is shortened, and a thrill feeling can be experienced in the game.

A game program according to claim 2 is a program for causing the computer to further realize the following functions in the game program according to claim 1 .
(13) A radar screen setting function for setting, on the image display unit, a radar screen for indicating a relative positional relationship between the character and the plurality of target objects.
(14) A character position display function for displaying the position of the character in the game space and the position of the target object on the radar screen.

  Here, a case where this game program is applied to an adventure game will be described as an example. In this case, first, a radar screen for indicating a relative positional relationship between the character and a plurality of treasure objects is set in the image display unit. Then, the position of the character in the game space and the position of the treasure object are displayed on the radar screen.

  In this case, the player can move the character toward the treasure object while referring to the radar screen. For example, the player can efficiently find a plurality of treasure objects by moving the character toward the treasure object closest to the character while referring to the radar screen.

A game program according to claim 3 is a program for causing a computer to further realize the following functions in the game program according to claim 1 or 2 .
(15) An indicator display function for displaying an indicator for notifying the position of the target object on at least one of the main screen and the sub screen.

  Here, a case where this game program is applied to an adventure game will be described as an example. In this case, an indicator for notifying the position of the treasure object is displayed on at least one of the main screen and the sub screen. For example, by displaying a mark for notifying the position of the treasure object on at least one of the main screen and the sub screen, the player searches for the treasure object using the mark as a mark. can do.

  For example, with only the scenery displayed on the main screen or the sub screen, it may take a very long time for the player to search for an object for treasure. For this reason, by displaying a mark for notifying the position of the treasure object on at least one of the main screen and the sub screen, the game required to find all the treasure objects is an extreme game. It can solve the problem of long time. That is, by using the sub screen, the player can enjoy the game in an appropriate time while maintaining the effect of simultaneously realizing the fun of guessing the target and the information notification.

In a game program according to a fourth aspect , in the game program according to any one of the first to third aspects, the position of the target object is randomly set in the game space in a range separated from the character by a predetermined distance or more. This function is realized in the target setting function.

  Here, a case where this game program is applied to an adventure game will be described as an example. In this case, the position of the treasure object is randomly set in the game space in a range that is away from the character by a predetermined distance or more. For example, if a treasure object is placed in the vicinity of a character, the treasure object may be easily found by the character, and the fun of the adventure game may be reduced. For this reason, here, the problem in realizing the adventure game is solved by restricting the treasure object from being placed in the vicinity of the character. Also, by placing treasure objects randomly in the game space at some distance from the character, the difficulty level is ensured, and the player can face the game with a fresh feeling every time, improving the interest can do.

A game device according to a fifth aspect is a game device capable of executing a game in which a character sequentially moves a plurality of targets in a game space. In this game apparatus, a main screen setting means for setting a main screen, which is a screen for a character, in an image display unit, and a target setting means for setting positions of a plurality of target objects that are targets aimed by the character in a game space, Control start means for issuing a control start command for starting control of the character, character control means for controlling the character in the game space, and control time calculation for calculating the time from when the control start instruction is issued Means, a main video display means for displaying the video of the game space within the viewing angle of the character on the main screen, a screen for the target object, and a sub-screen smaller than the main screen inside the main screen, setting a sub-screen setting means for the image of the game space including the target object to, be displayed on a sub-screen Sub-video display means, position determination means for determining whether or not the target object is located inside the game space within the viewing angle of the character being controlled, and a game in which the position of the target object is within the viewing angle of the character When located inside the space, a sub-screen erasing unit that erases the sub-screen for the target object from the image display unit, and whether or not all sub-screens for the target object have been erased from the image display unit. When it is determined that all the sub screens have been erased from the image display unit by the all sub screen erasure determination means and the all sub screen erasure determination means, the time when the character reaches the target object is stored as the control time. Control time storage means and control time display means for displaying the control time on the image display unit are provided.

A game control method according to a sixth aspect is a game control method in which a game in which a character sequentially moves a plurality of targets in a game space can be controlled by a computer. In this game control method , a control unit of a computer sets a main screen, which is a character screen, in an image display unit, and positions of a plurality of target objects that are targets aimed by the character, in a game space. A target setting step for setting the character, a control start step for issuing a control start command for starting control of the character, a character control step for controlling the character in the game space, and a point from when the control start command is issued A control time calculation step for calculating time, a main video display step for displaying video of the game space within the viewing angle of the character on the main screen, and a screen for the target object, which is smaller than the main screen inside the main screen. Sub screen setting step for setting the sub screen in the image display area The image of the game space including the object, and sub image display step of displaying the sub-screen, the target object, a position determining step of determining whether or not positioned inside the game space within the viewing angle of the character in the control When the position of the target object is located inside the game space within the viewing angle of the character, a sub-screen erasing step for erasing the sub-screen for the target object from the image display unit , and sub-screens for all target objects Is determined to have been erased from the image display unit, and the sub-screen erase determination step for determining whether or not all sub-screens have been erased from the image display unit. A control time storage step for storing the time at which the object is reached as the control time, and the control time And a control time display step of displaying on the display unit, to execute.

  In the present invention, an image within the viewing angle of the character is grasped on the main screen, and an image near the target object is grasped on the sub screen. Since the target object cannot be directly found in the video on the sub screen, the player guesses the location of the target object while viewing the video on the main screen and the video on the sub screen. Thus, in the present invention, the element of estimating the location of the target object can be added to the game.

  Further, when the position of the target object is located inside the game space within the viewing angle of the character being controlled, the sub screen for the target object is deleted from the image display unit. Therefore, the player can visually recognize that the character operated by the player is located in the vicinity of the target object when the sub screen is erased from the image display unit. In this way, the process of erasing the sub-screen from the image display unit can not only ensure a wide main screen area smoothly, but also give the player a sense of achievement of the goal. Alternatively, the information indicating that the vicinity of the target object has been reached can be notified to the player by deleting the sub-screen.

  Thus, in the present invention, by using the sub-screen, it is possible to simultaneously realize the fun of guessing and searching for a target and the achievement of reaching the target and reporting information. Thereby, the game provided with the completely different interest from the past can be provided with respect to a user.

[Outline of information notification system in adventure game]
Next, specific contents of the information grasping system in the adventure game will be described. FIG. 8 is a flow for explaining the system in the adventure game. In FIG. 8, in order to distinguish items relating to characters and items relating to treasure objects, “(ki)” is added to items relating to characters, and “(e)” is assigned to items relating to treasure objects. Is attached.

  In the following, the system will be described using an adventure game in which a character operated by a player acquires treasures while sequentially moving treasure buried points.

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

  For example, the basic game data includes data related to various images for a three-dimensional game space. The data related to various images for the three-dimensional game space includes, for example, model data for characters and model data of various objects such as buildings and trees. Further, the basic game data includes position coordinate data for arranging model data for the three-dimensional game space in the three-dimensional game space. Further, the basic game data includes image data for displaying a model photographed by the virtual camera on the television monitor 20. Further, the basic game data includes data used in the above system.

  Hereinafter, the term “character” may be used to mean “model data for a character”. In addition, the term “object” may be used to mean “model data for an object”. Further, the term “game space” is used to mean a “virtual game space” that is generally defined on a program.

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

  Here, for example, a character desired by the player is selected. More specifically, a character list composed of various types of characters is displayed on the television monitor 20 of the player. Here, the player operates the controller 17 to select an item corresponding to a desired character from the character list. The character corresponding to the item selected by this operation is recognized by the CPU 7 as the character operated by the player. In this way, the character is set (S3).

  Here, a supplementary explanation of character setting will be given. For example, when a character is selected by the player, the identification data for the character stored in the RAM 12 corresponding to this character is recognized by the CPU 7. Then, the character is managed by the CPU 7 using the character identification data. That is, the character is set by this processing. Note that a correspondence table indicating the correspondence between each of a plurality of characters (items) constituting the list and the identification data is defined in advance in the game program and stored in the RAM 12.

  When various settings of the adventure game are completed, the main screen 71 which is a screen for the main character is set on the television monitor 20 (see S4, the broken line in FIG. 3). Here, for example, the position coordinate data of the four corners defining the entire screen area of the television monitor 20 is read from the RAM 12 and recognized by the CPU 7. As a result, the entire screen area of the television monitor 20 is set as the main screen 71. Note that the position coordinate data of the four corners of the television monitor 20 are defined as predetermined values in the television monitor 20 used by the player, and these values are stored in the RAM 12.

  Subsequently, an instruction to start an adventure game is issued from the CPU 7 (S5). Then, the character is placed in the game space (S6). For example, the character is placed in the game space by causing the CPU 7 to recognize the position coordinate data indicating the position Pk of the character at the start of the game. For example, when the game is executed for the first time, the position coordinate data for initial execution stored in the RAM 12 is recognized by the CPU 7. When the game is continuously executed, the position coordinate data for continuous execution stored in the RAM 12 is recognized by the CPU 7. In the following description, the case where the position coordinate data for initial execution is recognized by the CPU 7 will be described as an example.

  Subsequently, a process of setting a virtual camera for each character arranged in the game space GS is executed by the CPU 7 (S7). The setting of the virtual camera includes the setting of the view frustum space Vs. For example, the virtual camera is set as follows.

  First, as shown in FIG. 4, the CPU 7 executes a process of arranging the virtual camera at the position of the character's eyes. The position of the character's eyes, that is, the position Pc of the virtual camera (see FIG. 5) is a predetermined height position (Z axis) based on the position (position defined by the XY plane) indicated by the position coordinate data of the character. Set in the direction position). The position of the character's eyes, that is, the position of a predetermined height (position in the Z-axis direction) is defined in advance in the game program.

  Here, the horizontal plane in the game space GS is defined by the X axis and the Y axis, and the vertically upward direction in the game space GS is defined in the direction in which the Z axis faces. Further, the origin, the direction in which the X axis faces, and the direction in which the Y axis faces are defined in advance in the game program.

  Next, as shown in FIG. 5, a view frustum space Vs to be imaged by the virtual camera is set in the game space GS. The view cone space Vs is the position coordinate data of the virtual camera position Pc, the position coordinate data of the virtual camera gazing point Pf, the angle data corresponding to the field angle α of the virtual camera, and the depth direction of the view cone space Vs. The game space GS is set based on position coordinate data for defining the range.

  More specifically, first, the CPU 7 recognizes position coordinate data for the gazing point indicating the position of the gazing point Pf of the virtual camera. Here, as shown in FIG. 5, the gazing point Pf of the virtual camera has a predetermined distance from the position Pc of the virtual camera in the gazing direction of the virtual camera (the sight line direction of the character) with respect to the position Pc of the virtual camera. It is set at a separated position. The gaze direction of the virtual camera corresponds to the direction of the character, for example, the direction of the line of sight of the character. The distance between the virtual camera position Pc and the gazing point Pf is defined in advance in the game program. Further, the Z coordinate of the gazing point Pf of the virtual camera is the same as the Z coordinate of the position coordinate data of the virtual camera.

  When the gazing point Pf of the virtual camera is set, an area displayed on the television monitor 20 in the game space GS is set as a view cone space Vs that can be seen from the character. The view frustum space Vs is defined as shown in FIG. First, the angle of view α of the virtual camera with respect to a straight line (reference line) connecting the virtual camera position Pc and the camera gazing point Pf is set. For example, the field angle α of the virtual camera is composed of a horizontal field angle αxy centered on the reference line and a vertical field angle αyz centered on the reference line. The angle of view α is set by causing the CPU 7 to recognize angle data corresponding to these angles of view αxy and αyz.

  Next, when the angle of view α (αxy, αyz) of the virtual camera is set, an area within the angle of view of the virtual camera (area within the angle of view) is determined. Then, by setting the camera viewpoint side surface (first surface) S1 and the surface (second surface) S2 away from the camera viewpoint in the field within the angle of view, the first surface S1 and the second surface S2 Is set as the view frustum space Vs.

  For example, the first surface S <b> 1 is set by causing the CPU 7 to recognize the position coordinate data of the first position separated from the position Pc of the virtual camera on the reference line by the first distance. Further, the second surface S2 is set by causing the CPU 7 to recognize the position coordinate data of the second position separated from the virtual camera position Pc on the reference line by a predetermined second distance. Here, the first distance and the second distance longer than the first distance are defined in advance in the game program. Then, based on the first distance and the second distance, the position coordinate data of the first position and the position coordinate data of the second position are calculated by the CPU 7.

  Then, the CPU 7 recognizes position coordinate data indicating the positions of the eight corners v1, v2, v3, v4, v5, v6, v7, and v8 of the view cone space Vs. Based on the positions of the corner portions v1, v2, v3, v4, v5, v6, v7, v8, the CPU 7 recognizes the position of the visual cone space Vs and the range of the visual cone space Vs in the three-dimensional game space GS. be able to.

  Here, the view cone space Vs is defined in a relative coordinate system with the position Pc of the virtual camera as the origin. For example, the direction from the virtual camera position Pc toward the camera gazing point Pf is set to the y-axis. In the game space GS, the surface that the character contacts, for example, the direction perpendicular to the ground surface is set as the z axis. A direction perpendicular to the y-axis and the z-axis is set as the x-axis. Further, the positions of the eight corners v1, v2, v3, v4, v5, v6, v7, v8 of the viewing cone space Vs are defined by an absolute coordinate system (XYZ coordinate system).

  Thus, once the view cone space Vs is set, when the character moves in the game space GS as will be described later, the view cone space Vs is set as needed in the above form in conjunction with the movement of the character. The

  Subsequently, the embedding point aimed by the character, that is, the position PE of the treasure object is set in the game space, and the treasure object is placed in the game space (S8). Here, first, as shown in FIG. 6, a circular region CR with the character position Pk as a base point is set by the CPU 7. For example, the circular region CR is a region having the character position Pk as the center and a predetermined distance as the radius. Next, position coordinate data indicating the temporary position Pe of the treasure object is randomly generated by the CPU 7 based on a random number generation program. Specifically, X coordinate data and Y coordinate data are calculated using a random number generation program, and these coordinate data are stored in the RAM 12. The temporary position Pe of the treasure object on the two-dimensional plane is determined by these X coordinate data and Y coordinate data. Further, the Z coordinate data of the ground surface is recognized and assigned to the Z coordinate data by the CPU 7. In this way, the temporary position Pe of the treasure object is set in the game space.

  Here, since the game space is a finite space, if a value exceeding the range of the game space defined on the XY plane is generated by the random number generation program, the random number is used until the value is within the range of the game space. That is, X coordinate data and Y coordinate data are repeatedly calculated.

  Note that the random number generation program is included in the game program. This random number generation program generates pseudo-random numbers based on a linear congruential method, a mixed congruential method, or the like.

  When the temporary position coordinate data of the treasure object is calculated, the CPU 7 determines whether or not the treasure object is located inside the circular region CR. For example, the CPU 7 determines whether or not the temporary position coordinate data of the treasure object matches the position coordinate data inside the circular region CR. When the temporary position coordinate data of the treasure object matches the position coordinate data inside the circular region CR, the position coordinate data indicating the temporary position Pe of the treasure object is based on the random number generation program. And regenerated by the CPU 7.

  On the other hand, when the treasure object is not located inside the circular region CR, for example, when the temporary position coordinate data of the treasure object matches the position coordinate data outside the circular region CR, The position coordinate data indicating the temporary position Pe of the treasure object is recognized by the CPU 7 as position coordinate data indicating the position PE of the treasure object. This position coordinate data is stored in the RAM 12. Note that the boundary of the circular region CR is included outside the circular region CR.

  FIG. 6A shows an example in which the temporary position Pe of the treasure object is located inside the circular region CR. The temporary position Pe of the treasure object (= the treasure object In this example, the temporary position PE) is located outside the circular region CR. That is, in the case of FIG. 6A, it is determined that the treasure object is too close to the character. For example, until the state shown in FIG. Calculated. In FIG. 6, only one treasure object is displayed for ease of explanation.

  This process is executed for each treasure object when there are a plurality of treasure objects. Then, the same number of position coordinate data as the number of treasure objects is recognized by the CPU 7 and stored in the RAM 12 by the above processing. Based on the position coordinate data, treasure objects are arranged in the game space. As a result, the treasure object is always placed at a position more than a predetermined distance from the character. Thereby, it can restrict | limit so that the object for treasures may not be arrange | positioned in the vicinity of a character. Hereinafter, in the present embodiment, a case where there are three treasure objects will be described as an example.

  Here, an example in which the game is executed for the first time is shown, but when the game is continuously executed, the position PE of the treasure object at the end of the previous game is set in the game space. . The position coordinate data indicating the position PE of the treasure object at the end of the previous game is stored in the recording medium 10 at the end of the previous game, and is loaded and stored from the recording medium 10 into the RAM 12 when the current game is executed.

  When the positions PE of the three treasure objects are determined, a treasure virtual camera for photographing each object is set at a position spaced apart from each treasure object by a predetermined distance (S9, FIG. 5). That is, the treasure virtual camera is a fixed camera arranged at a predetermined position in the game space. The distance data and the position coordinate data used for setting the virtual camera for treasure are defined in advance in the game program and are stored in the RAM 12. In this case, the position Pc of the virtual camera is the predetermined position, and the gazing point Pf of the camera is the position PE of the treasure object. The other data necessary for setting the viewing cone space Vs is performed similarly to the setting of the viewing cone space Vs for the character.

  When three virtual cameras are arranged in the game space, a sub-screen 72, which is a treasure screen, is set on the television monitor 20 (see S10, the broken line in FIG. 3). Here, the same number of sub-screens 72 as the number of treasure objects, for example, three sub-screens 72b, 72c, 72d are set in the main screen 71 of the television monitor 20. Further, each of the sub screens 72b, 72c, 72d is a predetermined area (partial area for sub screen) smaller than the entire screen area of the television monitor 20. More specifically, predetermined position coordinate data corresponding to each of four predetermined corner portions in the entire screen area of the television monitor 20 is read from the RAM 12 and recognized by the CPU 7. In this way, the sub screen 72 defined by the four corners, that is, the sub screen partial area is set. This process is executed by the CPU 7 for each of the three sub-screens 72b, 72c, 72d.

  Note that the positions of the four corners for defining the rectangular partial area are defined at predetermined positions inside the entire screen area of the television monitor 20. The position coordinate data indicating the positions of the four corner portions are defined in advance in the game program for each of the sub screens 72b, 72c, and 72d and stored in the RAM 12.

  Subsequently, a radar screen 73 for indicating a relative positional relationship between the character and a plurality of treasure objects is set on the television monitor 20 (S11). Here, for example, a predetermined area (partial area for radar screen) smaller than the entire screen area of the television monitor 20 is set as the radar screen 73. More specifically, predetermined position coordinate data of each of the four corners in the entire screen area of the television monitor 20 is read from the RAM 12 and recognized by the CPU 7. As a result, a predetermined partial area of the television monitor 20 is set as the radar screen 73.

  Note that the positions of the four corners for defining the rectangular partial area are defined at predetermined positions inside the entire screen area of the television monitor 20. The position coordinate data indicating the positions of these four corners are defined in advance in the game program and are stored in the RAM 12.

  Subsequently, when each screen is set as described above, a control start command for the character is issued from the CPU 7, and control of the character is started (S12). As a result, the character can be controlled in the game space.

  Here, when the control start command is issued from the CPU 7, the time from when the control start command is issued is calculated by the CPU 7. For example, when a control start command is issued from the CPU 7, the elapsed time is counted by the CPU 7 with the time when the control start command is issued from the CPU 7 as a reference time. For example, when the reference time is set to 0 (sec), the elapsed time from the reference time is stored in the RAM 12 every 1/60 (sec).

  In this state, when the player operates the controller 17 to move the character, an operation signal from the controller 17 is recognized by the CPU 7. Then, a process corresponding to this operation signal, for example, a process of calculating character movement direction data and movement amount data corresponding to the operation of the controller 17 of the player is executed by the CPU 7. Then, an instruction to move the character in the game space GS is issued from the CPU 7 based on the movement direction data and the movement amount data. Then, based on this command, the character moves in the game space GS in the movement direction indicated by the movement amount data in the movement direction indicated by the movement direction data.

  When the game space is defined by an absolute coordinate system including the X axis, the Y axis, and the Z axis, when the up key 17U is pressed, the character moves in the positive direction of the Y axis. Similarly, when the down key 17D is pressed, the character moves in the negative direction in the Y-axis direction. When the left key 17L is pressed, the character moves in the positive direction in the X-axis direction, and the right key 17R is When pressed, the character moves in the negative direction along the X axis. The amount of movement when the direction key (upward key 17U, downward key 17D, leftward key 17L, rightward key 17R) is pressed once is defined in advance in the game program. Stored in

  As described above, while the character is controlled in the game space GS, the game space included in the viewing angle of the character every predetermined time interval, for example, every one frame (ex. 1/60 (sec)). GS is taken by a virtual camera. For example, the inside of the view frustum space Vs, which is a subject to be photographed by the character virtual camera, is photographed by the virtual camera. And the image | video which image | photographed the inside of the view cone space Vs of the main character under control is displayed on the main screen 71 (S13). More specifically, the CPU 7 executes a process of projecting an object located inside the main character's viewing cone space Vs onto the first surface S1 of the viewing cone space Vs. When an instruction to display the object projected on the first surface S1 on the main screen 71 of the television monitor 20 is issued from the CPU 7, the video of the game space GS included within the viewing angle of the main character is 2 It is displayed on the main screen 71 using the image data for the dimensional space, that is, the image data corresponding to the object projected on the first surface S1.

  At this time, as shown in FIG. 3, the video of the game space in the vicinity of the treasure object is displayed on the sub-screen 72 (S14). Here, a game space in the vicinity of a treasure object is photographed by a virtual camera at predetermined time intervals, for example, every frame (ex. 1/60 (sec)). For example, the inside of the view frustum space Vs to be imaged by the treasure virtual camera is imaged by the virtual camera. Then, an image obtained by photographing the inside of the viewing cone space Vs is displayed on the sub screen 72. More specifically, the CPU 7 executes a process of projecting an object located in the view frustum space Vs to be photographed by the treasure virtual camera onto the two-dimensional space. When a command for displaying an object in the two-dimensional space on the sub-screen 72 of the television monitor 20 is issued from the CPU 7, the video image of the game space in the vicinity of the treasure object, that is, the scenery is displayed on the two-dimensional space. The image data corresponding to the object is displayed on the sub screen 72.

  In particular, the treasure object is displayed on the sub-screen 72 using the image data for the instructor. For example, as shown in FIG. 3, an indicator, for example, a star symbol, for notifying the position PE of the treasure object is displayed on each of the sub-screens 72b, 72c, 72d using the image data for the indicator. . That is, the treasure object is displayed on each of the sub-screens 72b, 72c, and 72d using an alarm, for example, a star symbol. On the other hand, when the character approaches the treasure object and the treasure object enters the character's viewing angle, an image obtained by projecting the treasure object (model) onto the two-dimensional space is displayed on the main screen 71. The Note that the image data for annunciator is loaded from the recording medium 10 into the RAM 12 and stored when the game program is loaded.

  As described above, in the sub-screens 72b, 72c, and 72d, the scenery in the vicinity of each of the three treasure objects is notified. Then, with reference to the scenery on the sub-screens 72b, 72c, 72d, the player compares the scenery on each of the sub-screens 72b, 72c, 72d with the scenery on the main screen 71 (described later), and the treasure is arranged. The location can be estimated and the character can be moved to the location of the treasure object.

  Further, at this time, as shown in FIG. 3, the position PE of the treasure object in the game space is displayed on the radar screen 73 (S15). Here, the position coordinate data indicating the position of each of the three treasure objects is recognized by the CPU 7, and the position corresponding to the position coordinate data is displayed on the radar screen 73 using the position image data. .

  For example, the position coordinate data of the treasure object on the XY plane is recognized by the CPU 7, and the relative position of the treasure object is displayed on the radar screen 73 based on the position coordinate data. Specifically, when the radar screen 73 is a screen corresponding to the entire area when the game space GS is viewed from above, the positions PE of the three treasure objects are displayed on the radar screen 73 as shown in FIG. Indicated by the X symbol.

  Here, the position Pk of the character under control is displayed on the radar screen 73. Here, the position coordinate data indicating the position Pk of the character under control is stored in the RAM 12 at predetermined time intervals, for example, every frame. Then, the position coordinate data is recognized by the CPU 7, and the position corresponding to the position coordinate data is displayed on the radar screen 73 using the position image data.

  More specifically, the position coordinate data of the character on the XY plane is recognized by the CPU 7, and the relative position of the character with respect to the treasure object is displayed on the radar screen 73 based on the position coordinate data. Specifically, when the radar screen 73 is a screen corresponding to the entire area when the game space GS is viewed from above, the character position Pk is indicated by a circle symbol on the radar screen 73 as shown in FIG. .

  Thus, on the radar screen 73, the positions PE1, PE2, PE3 of the three treasure objects and the position Pk of the character are notified. The radar screen 73 allows the player to move the character to the location of the treasure object while grasping a rough positional relationship between the character and the treasure object.

  Subsequently, the CPU 7 determines whether or not an object for treasure arranged in the same game space as the character is located inside the game space within the viewing angle of the character being controlled (S16). Here, the position coordinate data of the treasure object is recognized by the CPU 7, and it is determined whether or not the position indicated by the position coordinate data of the treasure object is included in the view cone space Vs of the character being controlled. CPU 7 determines.

  Then, when the position PE of the treasure object is located inside the game space within the character's viewing angle (Yes in S16), the treasure sub-screen 72 is erased from the television monitor 20 (S17). ). For example, when the treasure object position PE1 is located inside the game space within the viewing angle of the character, the treasure sub-screen 72b is erased from the television monitor 20. Similarly, when the positions PE2 and PE3 of the other objects are located inside the game space within the viewing angle of the character, the corresponding treasure sub-screens 72b and 72c are deleted from the television monitor 20.

  Here, when the position PE of the treasure object is located inside the game space within the viewing angle of the character, the identification data corresponding to the treasure object is the treasure object and each of the sub-screens 72b and 72c. , 72d, the CPU 7 recognizes the correspondence table. Then, the sub screens 72b, 72c, 72d corresponding to the identification data of the treasure object are specified by the CPU 7. Then, the CPU 7 issues a command for deleting the video displayed on the sub screens 72b, 72c, 72d from the sub screens 72b, 72c, 72d. Then, the CPU 7 issues a command for canceling the setting of the sub-screens 72b, 72c, 72d from the television monitor 20. In this way, the sub-screens 72b, 72c, 72d that provide information on treasure objects that fall within the viewing angle of the character are deleted.

  Here, the correspondence relationship between the identification data for identifying the treasure object and the sub-screens 72b, 72c, 72d displaying the video in the vicinity of the treasure object is managed by the CPU 7 based on the correspondence table. ing.

  When the position PE of the treasure object is not located within the game space within the character's viewing angle (No in S16), that is, when the treasure object is not within the character's viewing angle. The process of step 12 (S12) is executed by the CPU 7.

  Subsequently, the CPU 7 determines whether or not all the treasure sub screens 72 have been deleted from the television monitor 20 (S18). For example, when the identification data of the last treasure object among a plurality of treasure objects is recognized by the CPU 7, the images displayed on the sub-screens 72b, 72c, 72d corresponding to the identification data are The CPU 7 issues a command for deleting from the sub screens 72b, 72c, 72d and canceling the setting of the sub screens 72b, 72c, 72d.

  For this reason, for example, by making the CPU 7 determine whether or not an instruction to cancel the setting of the last treasure sub-screens 72b, 72c, 72d is issued from the television monitor 20, the sub-screens for all treasures are displayed. It is determined whether 72b, 72c and 72d have been deleted from the television monitor 20. Here, when the last treasure sub-screens 72b, 72c, 72d are released from the television monitor 20, all the treasure sub-screens 72b, 72c, 72d are deleted from the television monitor 20. Judge. When the last treasure sub screens 72b, 72c, 72d are not released from the television monitor 20, all the treasure sub screens 72b, 72c, 72d are not erased from the television monitor 20. Judge as if.

  If it is determined that all the sub-screens 72 have been deleted from the image display unit (Yes in S18), the time when the character reaches the last treasure object is stored as the control time Ts (S19). ). For example, when a command for canceling the setting of the last treasure sub-screens 72b, 72c, 72d is issued from the television monitor 20, whether or not the character under control has arrived at the position PE of the treasure object. Is determined by the CPU 7. When the character under control arrives at the position PE of the treasure object, a command for recording the time Ts when the character reaches the treasure object, that is, the arrival time (control time) in the RAM 12 is sent to the CPU 7. Issued by. Then, arrival time data indicating the arrival time Ts (control time), that is, time data indicating the time required for the character to acquire all treasure objects is stored in the RAM 12. The arrival time Ts is displayed on the main screen 71 of the monitor 206a of the A player.

  Then, processing for evaluating the character is executed by the CPU 7 in accordance with the arrival time data stored in the RAM 12. Here, for example, as shown in FIG. 7, the CPU 7 is referred to a correspondence table between the arrival time Ts and the level Lv of the player for this game, so that the level Lv of the player corresponding to the arrival time data is determined by the CPU 7. Recognized. Then, the level Lv of the player is displayed on the television monitor 20 using the image data (S20). In this way, the evaluation of the character according to the arrival time Ts is executed and notified by the CPU 7. Note that the correspondence table between the arrival time Ts and the level Lv is defined in advance in the game program and stored in the RAM 12.

  If all the sub screens 72 have not yet been erased from the image display unit (No in S18), that is, if an instruction to erase the third sub screen 72 has not been issued from the CPU 7, step 12 (S12). This process is executed by the CPU 7.

  After the character has found all the treasures, a screen asking whether or not to execute the game again is displayed on the television monitor 20 (S21, not shown). Here, when the player selects an item for executing the game again (Yes in S21), the process of step 3 (S3) is executed again by the CPU 7. Here, when the player selects an item for ending the game (No in S21), a process for saving the game result is executed by the CPU 7 (S22).

  As described above, in the present embodiment, the player can grasp the image within the viewing angle of the character on the main screen 71, that is, the scenery that falls within the viewing angle of the character. Further, the player can grasp information related to the treasure object, for example, the scenery in the vicinity of the treasure object on the sub-screen 72. Therefore, the player guesses the position PE of the treasure object based on the scenery on the sub screen 72 and experiences an interesting game of searching for the treasure object while looking at the scenery on the main screen 71. be able to.

  In addition, the player relies on the scenery of the main screen 71 and the scenery of the sub screen 72 to move the character operated by the player to the position PE of the treasure object, and then the treasure sub When the screen 72 is erased from the image display unit, it can be visually recognized that the character operated by the user is positioned in the vicinity of the treasure object. As described above, the process of deleting the sub screen 72 from the image display unit can not only ensure a wide area of the main screen 71 smoothly, but also provide position information to the player by this process. Further, at the timing immediately before the sub screen is erased, the main screen 71 is in a state in which at least a part of the sub screen 72 is reflected, so that the player who notices it has approached the target position. Can be obtained. Furthermore, since the sub-screen is sequentially erased thereafter, a sense of accomplishment of finding treasure objects one after another can be obtained, so that the effect of attracting the player more strongly into the game is exhibited.

  As described above, in the present embodiment, by using the sub screen 72, it is possible to simultaneously realize the fun of guessing the target, the satisfaction of achieving the target, and the notification of information. Thereby, the game provided with the completely different interest from the past can be provided with respect to a user.
