The computer operates as the video game apparatus 100 of the present invention.
[0025]
The video game apparatus 100 also includes an input unit 107 such as a dedicated controller connected via an interface circuit (I / F) 106. The input unit 107 includes a plurality of input units 107a such as buttons and analog joysticks. Thus, the operator can perform an operation on an operation target such as a fisherman character by performing input using the input unit 107a.
[0026]
FIG. 2 is an external view showing the input means 107 provided in the video game apparatus 100 of the present invention, and shows the external view as seen from the operator side during operation.
In the following description, “left and right” refers to the direction viewed from the operator during operation.
[0027]
As buttons serving as the input unit 107a, a cross button used for operations such as a direction instruction is arranged on the left side, and function buttons having symbols such as ◯, Δ, □, and X are arranged on the right side.
Each button does not have a fixed function, but can have various functions by changing a game or setting to be executed.
Also, two analog joysticks that can be operated in all directions of 360 degrees are arranged in the center.
[0028]
Returning to FIG. 1, the video game apparatus 100 further includes an interface circuit 108 used for outputting audio data. The audio data that is a digital signal output from the interface circuit (I / F) 108 is converted into a D / A converter 109. The analog signal converted by the D / A converter 109 is amplified by the pre-main amplifier 110 and then sent to the audio output means 120 such as a speaker that outputs audio based on the audio data.
[0029]
The video game apparatus 100 also includes an interface circuit 111 that is used to output image data. The image data that is a digital signal output from the interface circuit (I / F) 111 is converted into an analog signal by the D / A converter 112. Then, it is sent to display means 130 such as a television monitor that outputs an image based on the image data.
A single television monitor may be used as a device that serves as both the audio output means 120 and the display means 130.
[0030]
Next, image processing performed to represent a virtual game space using the video game apparatus 100 of the present invention will be described.
In the video game apparatus 100, the signal processor 102 performs various calculation processes based on the control of the CPU 101, and on the display area (frame buffer) that is a part of the image drawing processor 103 and the RAM 105 based on the calculation results. Writes image data to be drawn.
The RAM 105 has a non-display area and a display area. The non-display area stores intermediate calculation data in image drawing processing such as polygon data and texture data, and the display area is displayed on the display means 130. The image data to be stored is stored, and the stored image data is sent to the display means 130 via the D / A converter 112.

The polygons indicated by the polygon data are pasted with images indicating surfaces such as patterns and materials indicated as texture data, and indicate various objects in a virtual space.
[0032]
When displaying an image showing a virtual space on the display unit 130, the processing of the signal processor 102 based on the control of the CPU 101 causes the spatial coordinates of each vertex of the polygon in the three-dimensional space to be determined from the specified point. By converting to a plane coordinate indicating a two-dimensional image of the viewpoint viewing the specified direction, and further performing a perspective projection process, the plane coordinates of each vertex of the polygon in two dimensions are calculated, and based on the calculated plane coordinates Image data in which texture data is pasted on the polygon is generated, and the generated image data is stored in the display area of the RAM 105.
[0033]
The image data stored in the display area of the RAM 105 is sent to the display means 130 via the D / A converter 112 as described above, and an image of a viewpoint viewing the specified direction from the specified point is displayed. Is displayed.
[0034]
Next, processing during a game in the video game apparatus 100 of the present invention will be described.
FIG. 3 is a flowchart showing a non-operation target action determination process executed in the video game apparatus 100 of the present invention.
When the fishing game executed on the video game apparatus 100 of the present invention is started, the fishing character that is the operation target in the game is possessed based on the operation of the operator who operates the video game apparatus 100. Cast a lure (pseudo bait) attached to the tip of a reel (line) wound on a reel attached to a fishing rod, and put the lure into the water and a fish character that is not operated On the basis of the positional relationship, it is determined appropriately whether or not the fish character is stretched.
When it is determined that the fish character has been stretched, the video game apparatus 100 starts a process for fishing the fish character that has been stretched, and the operator uses the input means 107 to fish the fish character that has been stretched. An operation to make the hand character pick up is performed.
As a result, the fish character moves in relation to actions such as fishing of the angler character.
[0035]
In the video game apparatus 100, not only the input from the operator is received and the fisher character is made to act, but also the fish character that has been stretched is acted on the basis of a predetermined routine.
In the video game apparatus 100, as a process of causing the fish character to be hung up, the current position of the fish character in the virtual space in the game is started from the control of the CPU 101 that executes the computer program 201 stored in the RAM 105. Within a predetermined range, a movement point that is a target point of action is determined by a random number (S101).
Then, it is determined whether or not the fish character that has been stretched is in an operation such as normal swimming, swinging, and girder washing described later (S102).
[0036]
If it is determined in step S102 that the operation is not in progress (S102: NO), a plurality of preset operations, specifically movement points, are controlled based on the control of the CPU 101 that executes the computer program 201 stored in the RAM 105. The action to be performed by the fish character is determined by using random numbers from among the actions of normal swimming toward the head, swinging the head in the water, washing the water to jump on the water, and the side swimming action (S103), and the start and viewpoint of the determined action The fish character motion subroutine for determining the above is started (S104).
Note that the probability and required time to be determined for each action are preset, and the type of action determined based on the set probability passes an argument for specifying the action to the activated fish character action subroutine. Is communicated by
If it is determined in step S102 that the device is operating (S102: YES), the processes shown in steps S103 and S104 are not performed.
[0037]
In the video game apparatus 100, it is determined whether or not the stretched fish character moving in relation to the angler character has been picked up based on the distance between the fisher character and the fish character and the length of the thread. If it is determined that the fish has been caught (S105: YES), a predetermined image for capturing the fish character is displayed and the fishing process is terminated.
[0038]
When it is determined in step S105 that the fish character that has been caught has not been picked up yet (S105: NO), it is determined whether or not the fish character that has been caught has arrived at the movement point determined in step S101. (S106) When it is determined that the mobile point has been reached (S106: YES), the process returns to step S101 and the subsequent processing is repeated.
[0039]
When it is determined in step S106 that the movement point has not been reached (S106: NO), it is determined whether or not the action started by the fish character action subroutine started in step S104 has ended (S107). Is determined to be completed (S107: YES), the process returns to step S101 and the subsequent processing is repeated.
[0040]
If it is determined in step S107 that the operation has not ended (S107: NO), the process returns to step S105 and the subsequent processing is repeated.
In this way, the action determination process of the fish character at the time of fishing of the fish character that has been stretched is executed.
[0041]
Next, a description will be given of the motion start and viewpoint determination processing executed as the fish character motion subroutine started in step S104 in the fish character behavior determination processing.
FIG. 4 is a flowchart showing the operation start and viewpoint determination processing of the non-operation target executed in the video game apparatus 100 of the present invention.
In the video game apparatus 100, based on the control of the CPU 101 that executes the computer program 201 stored in the RAM 105, whether or not the action determined based on the argument that specifies the action passed when the subroutine is started is normal swimming. Is determined (S201).
If it is determined in step S201 that the determined action is a normal swim (201: YES), the determined normal swim action is changed to fish based on the control of the CPU 101 that executes the computer program 201 stored in the RAM 105. The character is started (S202), and when the determined action is a predetermined action, here, a normal swim, on the line segment having both ends of the fisher character that is the operation target and the fish character that is the non-operation target, A point where the ratio of the distance from both ends is a predetermined value, for example, 3/7 is calculated (S203), the calculated point is set as a predetermined point (S204), and the angler character that is the operation target from the set predetermined point Is displayed on the display unit 130 as an image of the viewpoint set for the operation (S205).
[0042]
Note that arbitrary points in the respective polygons forming the fisher character and the fish character, for example, the center of gravity, the tip of the fishing rod, and the positions of the eyes of the fish character are set in advance as points that become both ends of the line segment.
Further, the line segment is not necessarily a line segment in the three-dimensional space, and may be a line segment projected on a two-dimensional plane having an arbitrary height.
The predetermined point as the position of the viewpoint is not a fixed point, but is recalculated and reset every time the fisher character or fish character moves. It is possible to intuitively grasp changes in the position of the fish character such as the distance and direction from the hand character to the fish character.
[0043]
If it is determined in step S201 that the determined action is not a normal swimming action (S201: NO), it is determined whether or not the determined action is swinging based on an argument that specifies the action (S206). .
If it is determined in step S206 that the determined motion is swinging (S206: YES), the determined swing motion is started by the fish character (S207), and the viewpoint of looking at the front of the fish character from underwater is determined. The image is displayed on the display unit 130 as an image of the viewpoint set for the determined operation (S208).
[0044]
If it is determined in step S206 that the determined motion is not a swing motion (S206: NO), it is determined whether or not the determined motion is flushing based on an argument that specifies the motion (S209). .
In step S209, when it is determined that the determined action is the flushing operation (S209: YES), the determined character washing operation is started by the fish character (S210), and an image of the viewpoint of viewing the fish character from the water is displayed. Then, the image is displayed on the display unit 130 as an image of the viewpoint set for the determined operation (S211).
[0045]
In step S209, when it is determined that the determined action is not an action for washing the elbow (S209: NO), it is determined that the decided action is a sidestroke, which is an action other than normal swimming, swinging and washing. Then, the determined lateral swimming action is started by the fish character (S212), and the viewpoint image looking up at the fish character from below the fish character is displayed as the viewpoint image set for the determined action. The information is displayed on the means 130 (S213).
[0046]
In this way, the fish character that has started the movement by the processing of the fish character action subroutine performs a characteristic action while moving to the movement point as a movement related to the angler character, By displaying it as an image of a viewpoint suitable for the movement, the fish character feels lively and stimulates the curiosity of the operator.
While the fish character is moving, the viewpoint is not fixed, and in particular, the viewpoint of looking at the front of the fish character from underwater, the viewpoint of looking at the fish character from above the water, and the viewpoint of looking up at the fish character from below the fish character. In this case, an image of the viewpoint of viewing the angler character from the rear is displayed at a predetermined time interval such as 5 seconds.
By appropriately displaying an image of the viewpoint of viewing the fisherman character from the rear, the operator can obtain a feeling of lifting as if he is a fisherman character and can experience pseudo fishing.
[0047]
Next, a process that is executed based on an operation performed by the operator in order to cause the fisher character to pick up the fish character that has been stretched will be described.
The operation of picking up the fish character caught on the fisherman character is, for example, an operation of rotating an analog joystick that is one of the input units 107a of the input unit 107 and an operation of pressing a cross button that is one of the input units 107a. By rotating the right analog joystick clockwise, the angler character winds the thread around the reel, and by pressing the left cross button in either the up, down, left, or right direction, the angler character can change the fishing rod. To move up, down, left or right.
[0048]
Note that the operation of tilting the fishing rod to the fisher character is not limited to the operation of pressing the cross button in either the up, down, left, or right direction. For the left and right, the function buttons indicated by □ and the function buttons indicated by ○ are used. In other words, any input unit 107a may be assigned an operation for tilting the fishing rod to the left or right as long as an input indicating one of the two opposite directions can be performed.
[0049]
FIG. 5 is a flowchart showing a first operation process executed by the video game apparatus 100 of the present invention at the time of catching a fish character that is a non-operation target.
In the video game apparatus 100, when an input of an operation for rotating an analog joystick that is one of the input units 107a of the input unit 107 is received, the rotation angle is determined based on a change in the direction of the operation input by the analog joystick. (S301) The length (line length) of the yarn corresponding to the determined rotation angle is calculated (S302), and a process of winding the yarn for the calculated length around the reel is performed (S303).
[0050]
FIG. 6 is a flowchart showing a second operation process executed when the fish character that is a non-operation object is lifted, which is executed in the video game apparatus 100 of the present invention.
In the video game apparatus 100, when an input of an operation of pressing the cross button, which is one of the input units 107a of the input unit 107, is received, the received direction is one of the left and right (two opposite directions). For example, when an input indicating the right is received, the viewpoint of the image displayed on the display unit 130 is detected based on the control of the CPU 101 that executes the computer program 201 stored in the RAM 105 (S401).
Then, it is determined whether or not the detected viewpoint is a viewpoint for viewing the operation target from the predetermined point set in step S204 of FIG. 4 in the fish character motion subroutine (S402), and the viewpoint for viewing the operation target from the predetermined point. When it is determined that the point of view is different from the viewpoint (S402: NO), the action target is acted in the first direction, here, the fishing rod character is tilted to the right of the angler character that is the operation target (S403). ).
[0051]
The viewpoint different from the viewpoint of viewing the operation target from a predetermined point is a viewpoint other than the viewpoint of viewing the angler character from the front, specifically, the viewpoint of viewing the front of the fish character from the water, the viewpoint of viewing the fish character from the water, and There are viewpoints such as a viewpoint of looking up at the fish character from below the fish character and a viewpoint of looking at the fisher character from behind.
Among these viewpoints, in particular, in the viewpoint of viewing the fisher character from behind, the left and right for the fisher character and the left and right of the image displayed on the display means 130, that is, the left and right for the operator are the same.
For this reason, when the operator performs an input indicating the right on the input unit 107, the fisherman character displayed on the display unit 130 moves to the right in the image displayed on the display unit 130.
The operation in which the direction of the operator's input and the direction of the image displayed on the display unit 130 coincide with each other is an operation that is widely used in video games. In addition, the operation can be performed without any sense of incongruity.
[0052]
Also, in the video game apparatus 100, when it is determined in step S402 that the viewpoint is to view the operation target from a predetermined point based on the control of the CPU 101 that executes the computer program 201 stored in the RAM 105 (S402: YES), the operation is performed. A process is performed in which the angler tilts the fishing rod to the left side of the angler character that is the operation target (S404).
[0053]
The viewpoint of viewing the operation target from a predetermined point is the viewpoint of viewing the fisher character from the front, and the left and right for the fisher character are opposite to the left and right of the image displayed on the display means 130, that is, the left and right for the operation target. Become a direction.
In the case of a viewpoint from which the fisher character is viewed from the front, the operator performs an input indicating the right on the input unit 107, and thus the fisher character displayed on the display unit 130 moves to the right for the fisher character. If there is, the angler character will act to the left on the image displayed on the display means 130 in response to the input indicating the right, and the operator will feel uncomfortable both sensibly and empirically. become.
Therefore, as shown in steps S402 and S404, only when the angle of the fisherman character is viewed from the front, the operator makes an input indicating the right to the input means 107, so that the angler displayed on the display means 130 is displayed. If the character moves to the left side for the angler character, the angler character displayed on the display means 130 is displayed on the right side in the image displayed on the display means 130 in response to an input indicating the right by the operator. The operator can operate without feeling uncomfortable.
The second operation process shown in steps S401 to S404 is a process for eliminating the sense of incongruity in operation by reversing the direction of the action according to the viewpoint as described above.
[0054]
It should be noted that since such a sense of incongruity does not occur in the upper and lower directions, the video game apparatus 100 accepts an input of an operation of pressing the cross button that is one of the input units 107a of the input unit 107 regardless of the viewpoint. In some cases, when the accepted direction is up, the fishing character is caused to tilt the fishing rod upward (raise the fishing rod), and when the accepted direction is down, the angler character is caused to tilt the fishing rod down. Perform the process (lowering the fishing rod).
That is, when there are two or more combinations of opposite directions, such as left and right and up and down, for one combination, here left and right, the direction of action of the operation target is reversed with respect to the input direction received based on the viewpoint, For other combinations, here up and down, the direction of the action of the operation target is made constant with respect to the accepted input direction regardless of the viewpoint.
[0055]
However, when there are two or more combinations of conflicting directions, the direction of the action to be operated may be reversed with respect to the input in each direction.
For example, in the case of application to a video game in which an operation target that is a policeman character follows a non-operation target that is a thief character who is trying to escape, the front, rear, left, and right directions are respectively input by the cross button that is the input unit 107a. Assume that it is assigned.
When applied to a video game in which the direction of operation is assigned in this way, when the policeman character is displayed from behind, the front side of the display means 130 viewed from the operator is behind the policeman character, and the policeman character is displayed from the front. In this case, since the front side of the display means 130 viewed from the operator is the front for the policeman character, the direction of action for the operation target with respect to the received input direction is reversed not only in the left-right direction but also in the front-rear direction. By doing so, it is possible to provide the operator with an uncomfortable operation.
[0056]
As described in the first operation process and the second operation process, by accepting an operation of winding a thread and an operation of defeating a fishing rod, and by causing a fisher character to act, what is the traveling direction of the fish character in accordance with the movement of the fish character? On the other hand, by defeating the fishing rod, it is possible to produce an action at the time of fishing to wind up the thread while preventing the lure hanging from the tension from coming off.
[0057]
Next, the viewpoint for viewing the operation target will be described.
FIG. 7 is a schematic diagram for explaining the viewpoint of an image displayed on the video game apparatus 100 of the present invention.
In FIG. 7, A indicates a fisher character that is an operation target, B1 and B2 each indicate a fish character that is a non-operation target, and the positional relationship between the operation target and the non-operation target is schematically shown from above.
On the line segment having the operation target and the non-operation target as both ends, a predetermined point where the ratio of the distance from both ends is a predetermined value, here 3/7, is C1 and C2, for example, the video game apparatus 100 of the present invention. In the case where the fish character caught in the area swims normally, an image from the viewpoint of viewing the angler character from C1 and C2 is displayed from the display means 130.
[0058]
The predetermined point is not a fixed point but a point that moves according to the position of the fish character. When the fish character moves from B1 to B2 as shown in FIG. 7, the predetermined point also moves from C1 to C2. To do.
The predetermined point on the line segment with the fisherman character and the fish character at both ends moves from C1 to C2, so that the image of the fisherman character displayed on the display means 130 displays the right side for the fisherman character. Therefore, the operator can intuitively grasp that the fish character is moving in the right direction for the angler character from the displayed image.
The predetermined point is fixed to a point on the line segment with the fisher character and the fish character at both ends, and the ratio of the distance from both ends is 3/7, so the fish character moves from B1 to B2. By approaching the fisherman character, the predetermined point also moves from C1 to C2 to approach the fisherman character, and the image of the fisherman character displayed on the display means 130 approaches the fisherman character. Specifically, since the fisherman character changes so as to be displayed larger, the operator intuitively recognizes that the fish character is moving closer to the fisherman character from the displayed image. Can be grasped.
[0059]
Next, an image displayed on the display unit 130 of the video game apparatus 100 of the present invention will be described.
FIG. 8 is an explanatory view showing an image displayed on the display means 130 of the video game apparatus 100 of the present invention.
FIG. 8 shows an image when the fish character is stretched from an underwater viewpoint. In the image, a fish character 1001 swimming in the water, a lure 1002 that the fish character is chasing, and a thread to which the lure 1002 is tied. 1003 is shown.
In FIG. 8, time information is displayed on the upper left, “TIME” 1010 indicates the time during the game, and “YOUR TIME” 1011 indicates that the fish character currently being caught is stretched. The elapsed time is indicated, and “TOTAL” 1012 indicates the elapsed time of the game.

A number indicated as “DRAG” 1015 on the lower left side of the screen indicates a drag value indicating a load that prevents the reel yarn from being pulled out.
In the two bar graphs shown to the right of the drag value, the upper graph shown as “TENSION” 1016 shows the tension of the thread, and when the thread loosens, the bar chart becomes shorter and the thread is stretched. And the bar graph becomes longer.
The lower graph shown as “HOOK” 1017 indicates the degree of tension.
Further, an oval window 1018 shown on the lower right side shows an image viewed from the viewpoint of the fish character.
[0060]
9, 10 and 11 are explanatory diagrams showing images displayed on the display means 130 of the video game apparatus 100 of the present invention.
9, 10, and 11 are images when the action of the fish character is determined to be normal swimming in the above-described viewpoint determination process, on the line segment that has both ends of the fisher character and the fish character, The image of the viewpoint which sees a fisherman character from the predetermined point whose ratio of the distance from both ends is a predetermined value is shown.
[0061]
In the image shown in FIG. 9, an angler character 1004 that is an operation target is displayed. The angler character 1004 has a fishing rod 1005, and a line 1003 extends from the tip of the fishing rod 1005. A fish character that is not displayed is stretched at the tip of the thread 1003 to be played.
The fisher character 1004 stands upright on a boat 1007 having a handle 1006, and a mountain range 1008 spreads far away as the background of the boat 1007.
Note that “TIME” 1010, “YOUR TIME” 1011, “TOTAL” 1012, “LINE” 1013, “DEPTH” 1014, “DRAG” 1015, “TENSION” 1016, and “HOOK” 1017 are the same as those in FIG. Therefore, the description will be omitted with reference to FIG.
[0062]
FIG. 10 shows a state in which the time during the game has progressed from FIG.
In FIG. 10, reference numerals are omitted, but the following description will be given assuming that the same reference numerals as those in FIG. 9 are given.
From the image shown in FIG. 10, it can be understood that the fish character has moved to the right side for the fisher character 1004 from the angles of the handle 1006 and the boat 1007 as compared to the image of FIG. 9.
In addition, as can be seen from the angle of the thread 1003, the fisher character 1004 performs an action of defeating the fishing rod 1005 to the left side for the fisher character 1004, and the operator acts on the fisher character 1004 and the left side for the fisher character 1004. In order to perform the action of defeating the fishing rod 1005, an input indicating the right is performed on the input means 107.
As shown in FIG. 10, in an image of a viewpoint in which the fisher character 1004 is viewed from a predetermined point, the angler character 1004 displayed on the display unit 130 is displayed when the operator inputs the right to the input unit 107. The fisher character 1004 moves to the left side and on the right side of the image displayed on the display means 130, so that the operator can operate without feeling uncomfortable both sensibly and empirically. .
[0063]
FIG. 11 shows a state in which the time during the game has further progressed from FIG.
In FIG. 11, reference numerals are omitted, but the following description is given assuming that the same reference numerals as those in FIG. 9 are shown.
From the image shown in FIG. 11, compared to the image of FIG. 10, the boat 1007 is hardly displayed, the fisherman character 1004 and the mountain range 1008 are displayed, and the fisherman character 1004 is greatly viewed from below. By being displayed, it is possible to grasp that the fish character is approaching to the vicinity of the foot of the fisher character 1004 and the game is progressing to the point where it is about to be picked up.
In addition, since the angler character 1004 is displayed in a large size, the expression of the face of the angler character 1004 and the frontal movements such as how to move both hands are described in detail. The time to reach the storm surge will be displayed in a dynamically produced state.
The “LINE” 1013 displays the length of the thread 1003 from the tip of the fishing rod 1005 to the lure, but the operator intuitively grasps the distance to the fish character without looking at the “LINE” 1013. Therefore, it is possible to concentrate on the moving image portion such as the angler character 1004 without worrying about the numerical value.
[0064]
FIG. 12 is an explanatory view showing an image displayed on the display means 130 of the video game apparatus 100 of the present invention.
FIG. 12 is an image when the action of the fish character 1001 is determined to swing during the viewpoint determination process described above, and shows an image of a viewpoint looking up at the fish character 1001 from below the fish character 1001.
