[0001]
BACKGROUND OF THE INVENTION
  On the computer,For running a given gameprogramEtc.
[0002]
BACKGROUND OF THE INVENTION
Conventionally, various types of games have been proposed, but there is no game that can be enjoyed by rolling and manipulating an object that grows into a snow dharma type by joining (attaching) other colliding objects on the surface. .
[0003]
[Problems to be solved by the invention]
In the game, it is important how to make the “movement that looks like that” according to the setting of the character. When the object to be enlarged is considered to be a character, the “movement that looks like that” is, for example, that the object is rolled up and down and left and right irregularly according to the irregularities of its appearance (appearance shape). .
[0004]
However, a large number of objects are coupled to the surface of the object to be enlarged, and the appearance shape always changes irregularly. For this reason, if a motion (rolling) is to be obtained from the appearance shape itself, a large number of surfaces including a large number of already-coupled objects must be subjected to computation, and enormous computation processing is required. As a result, there arises a problem that the motion calculation cannot keep up with the drawing rate of the game screen. Conversely, if the motion calculation is performed as a simple model (for example, a single primitive) regardless of the appearance shape of the object, there is a problem in that the movement in the game screen is simplified and aroused.
[0005]
The present invention has been made in view of the above-described problems, and the object of the present invention is to make an object corresponding to the appearance shape of an object that joins another object that collides with the surface and enlarges into a snow dharma type. It is to realize the movement that looks like it more easily.
[0006]
[Means for Solving the Problems]
  To solve the above problem,FirstAccording to the invention, an apparatus including a processor sets a virtual space in which a plurality of objects including a first object and a second object are arranged by calculation and control by the processor, and the apparatus is viewed from a given viewpoint. Game information for generating a virtual space image and executing a given game,
  Point setting means for setting a plurality of displacement points that can be displaced only in a predetermined direction to form a rolling reference plane of the first object (for example, the motion calculation model setting unit 222, the motion calculation model information 53 in FIG. 6). ) And the collision determination means (for example, the game calculation unit 22 in FIG. 6) for determining the collision between the first object and the second object, and the collision determination means, the first object When the second object is coupled by the coupling means (for example, the display model coupling unit 221 and the coupling history information 57 in FIG. 6) and the second object are coupled at the collision position. Displacement point control means for displacing the displacement point close to the position to a new position along the predetermined direction (for example, the motion calculation model setting unit 222 in FIG. Dell information 53), rolling control means for controlling rolling of the first object in the virtual space based on the displacement point (for example, the game calculation unit 22, motion calculation model information 53 in FIG. 6), , Including information for causing the device to functionGame information.
[0007]
  Also,11thThe present invention sets a virtual space in which a plurality of objects including a first object and a second object are arranged, generates an image of the virtual space viewed from a given viewpoint, and executes a given game A game device,
  Point setting means for setting a plurality of displacement points that can be displaced only in a predetermined direction to form a rolling reference plane of the first object, and collision determination means for determining a collision of the second object with respect to the rolling reference plane And a collision determination unit that performs a collision determination between the first object and the second object, and the second object is coupled to the first object at the collision position when the collision determination unit determines that the collision has occurred. When the second object is coupled by the coupling means, a displacement point control means for displacing the displacement point close to the collision position to a new position along the predetermined direction, and the first object Rolling control means for controlling rolling in the virtual space based on the displacement point.It is a game device.
[0008]
  FirstOr11thAccording to this invention, when the second object collides with the first object, the combining means connects the second object to the first object at the collision position.
[0009]
For example, when the first object and the second object are displayed in close contact with each other, the collision position mentioned here corresponds to the closest vertex coordinates of the two objects, the closest surface, the center coordinates of the surface, and the like. . The combining method includes, for example, a method of setting a hierarchical structure of a display model (a model for displaying the appearance of an object on the game screen), or modeling data itself of the display model of the first object as the second object. This is implemented by a method of changing to a combined model. Therefore, after the collision, the first object and the second object are displayed together.
[0010]
On the other hand, a plurality of displacement points are set by the point setting unit in the first object, apart from the information of the display model combined by the combining unit, and a rolling reference plane is formed. When the second object collides with the first object, the displacement point control means selects a displacement point close to the collision position, changes the position of the displacement point appropriately, and changes the rolling reference plane. Then, a rolling reference plane is formed in accordance with a change in the unevenness of the first object combined with the second object.
[0011]
  Then, the rolling control means calculates a motion based on the displacement point so that the first object rolls on the rolling reference plane. Thus, for example, because the first object is square,ShiIt can be expressed easily as it rolls. Further, for example, by referring to the inclination of the rolling reference plane formed by the displacement point adjacent to the ground contact position, the right and left tilt from the vertical of the straight line connecting the center of the first object and the ground contact position is obtained. It is possible to obtain a rolling that appears as if the center of gravity shifts to the left and right according to the unevenness.
[0012]
  Therefore,FirstOr11thAccording to the invention, even if the first object and the second object are combined to make the appearance shape complicated, it is possible to express the appearance of rolling that looks like the appearance shape irregularities with a small calculation load.
  If the first object is applied to an object that grows in a snow dharma style that the player operates, and the second object is applied to an object placed in the surrounding area, it is easy to make appropriate rolling according to the appearance irregularities of the enlarged object. Can be realized.
[0013]

[0014]
  SecondAccording to the invention ofFirstThe displacement point control means sets the displacement point based on the shape of the second object coupled to the first object.
[0015]
Based on the shape of the second object means based on the relative posture of the second object in a state of being coupled to the first object. That is, for example, the displacement point control means sets the displacement point along the appearance shape in which the second object is coupled and the unevenness is generated, and forms the rolling reference plane.
Therefore, it is possible to cause the first object, which is uneven by combining the second object, to perform more irregular rolling according to the unevenness of the external shape.
[0016]
  Furthermore,ThirdInventionAs,FirstOrSecond inventionInformation for determining the number of displacement points to be displaced based on the shape of the second object (for example, the motion calculation model setting program 422 in FIG. 6, Including hierarchy information 514 and join history information 57)Configure game informationIt's also good.
[0017]
  ThirdAccording to the invention ofFirstOrSecondIn addition to the effects similar to the invention of the present invention, the displacement point control means makes the number of displacement points to be displaced appropriate so that more detailed rolling along the external shape of the first object combined with the second object. A reference plane can be formed. Therefore, it is possible to adjust the degree of rolling that is faithful to the unevenness of the appearance shape.
[0018]
  4thThe invention ofFirstAny of ~ 3InventionGame information, information for causing the apparatus to function a combination determination unit (for example, the combination determination unit 223 in FIG. 6) that determines whether or not the first object and the second object can be combined.

[0019]
  4thAccording to the invention ofFirstAny of ~ 3InventionThe second object that can be combined with the first object can be set by determining whether or not it can be combined.
  For example, when the second object is a very long rod-shaped object, depending on the positional relationship to be combined, for example, the first object is in a state of being skewered by the second object, and the first object is rolled. It may be extremely unnatural. Therefore, for example, the second object is set to be unlinkable when colliding at the end.
  Therefore, it is possible to prevent the occurrence of unnatural rolling.
[0020]
  Also,5thInventionAs,4th inventionInformation for determining whether or not to combine based on the size and / or weight of the second object set in advance (for example, the combination determination program of FIG. 6). 423, radius 551, volume 552, representative dimension 641).Configure game informationIt's also good.
[0021]
  5thAccording to the invention of4thIn addition to the same effects as the present invention, the size and weight of the second object coupled to the first object can be controlled so that the unevenness of the appearance shape of the first object can always be within a predetermined range.
  Therefore, it is possible to prevent a situation in which an unnatural rolling occurs and to always realize a stable rolling and maintain an exhilarating feeling of an operation which is an important element of the game performance.
[0022]

Contains information for functioning (for example, model calculation program 426 for motion calculation in FIG. 6)Game information.
[0023]
  6thAccording to the invention ofFirstAny of ~ 5InventionThe same effect as the above is achieved, and the position of the displacement point is made uniform. That is, the unevenness difference of the rolling reference surface is reduced to make the first object easier to roll.
  Therefore, for example, if the position of the displacement point is made uniform with the rolling of the first object, the combined posture is inappropriate and difficult to roll immediately after the second object is combined, but the shape becomes familiar as the rolling is repeated. With this, you can realize the sensation of gradually rolling and the movement that looks more like that.
[0024]
  Also,7thInventionAs,6th inventionInformation for causing the device to function a combination mode changing unit (for example, the display model familiarity calculation unit 225 in FIG. 6) that changes the combination mode of the second objects combined by the combining unit. (For example, the display model familiarity program 425 in FIG. 6), information for the adaptation means to function in accordance with the change by the combination mode changing means (for example, the display model familiarity program 425 in FIG. 6), ,includingConfigure game informationIt's also good.
[0025]
  The combination mode of the second object includes a combination positional relationship / attitude with the first object, a shape in a combined state, and the like.
  7thAccording to the invention of6thThe effect similar to that of the present invention is achieved, and the connection mode changing means changes the connection mode of the second object. For example, when the rod-shaped second object is coupled so as to protrude from the first object, the posture and the coupling position of the second object are changed so that the longitudinal direction of the second object is along the surface of the first object. Is done.
[0026]
Specifically, for example, a portion of the second object positioned outside the rolling reference plane that changes the coupling mode stepwise so that the center of gravity of the second object is closest to the center of the first object is moved. The display model can be deformed so as to be bent and compressed along the dynamic reference plane.
Therefore, when the first object rolls, the familiarity of the apparent shape is expressed, and the rolling can be made more like that.
[0027]
  8thThe invention ofFirstAny of ~ 7InventionSeparating means for separating the second object combined by the combining means from the first object in accordance with a given condition (for example, the display model combining unit 221 in FIG. 6) When the second object is separated by the separation means by the separation means by the information for causing the device to function (for example, the display model combining program 421 in FIG. 6) and the displacement point control means, the second object Information for displacing a displacement point close to the collision position to a new position along the predetermined direction (for example, the motion calculation model setting program 422 in FIG. 6).Game information.
[0028]
  8thAccording to the invention ofFirstAny of ~ 7InventionThe second object once combined is separated under a predetermined condition, and the rolling reference plane is reset based on the shape of the first object after separation.
[0029]
Therefore, for example, if the second object in the already-coupled state is separated according to the relative momentum on the condition that the first object collides with the obstacle object, the one that has already been coupled under the influence of the collision. It is possible to easily realize the disengagement. Moreover, by separating the second object and resetting the rolling reference plane, it is possible to realize a state in which the place where the second object is detached becomes distorted and the collision affects the subsequent rolling.
[0030]

    [InventionEmbodiment]
  [First Embodiment]
  Next, a first embodiment to which the present invention is applied will be described in detail with reference to FIGS.
[0035]
The first embodiment will be described as a “ball rolling” game in which a ball is rolled and other objects are bonded (attached) to the surface in a snow dharma style and compete for how to increase in time. What is applied is not limited to this. For example, a game in which a character having a motif of rolling an object appears can be applied regardless of the character setting or game story setting.
[0036]
[Description of configuration]
First, the configuration in the present embodiment will be described.
FIG. 1 is a diagram showing an example when the present invention is applied to a consumer game device 1200. As shown in the figure, the consumer game device 1200 includes game controllers 1202 and 1204 and a main device 1210, and is connected to a display 1220.
[0037]
Game information such as a game program and data necessary for executing a game is stored in, for example, a CD-ROM 1212, an IC memory 1214, a memory card 1216, etc., which are information storage media detachable from the main unit 1210.
The main device 1210 executes various game processes based on the game information read from the information storage medium and the operation input signals from the game controllers 1202 and 1204, and displays a game screen on the display 1220.
[0038]
While viewing the game screen displayed on the display 1220, the player operates the cross key, analog stick, various buttons, and the like provided in the game controllers 1202 and 1204, and inputs a ball movement operation to enjoy the game. .
[0039]
[Description of game contents]
FIG. 2 is a diagram showing an example of a game screen by the home game device 1200. As shown in FIG. The game screen is displayed, for example, as a 3DCG image using polygons when the object space in which the objects are arranged is viewed from a given viewpoint.
[0040]
The player becomes a character C, rolls a mysterious sphere B that joins the collided object to the surface, and successfully collides with the objects E1 to E3 arranged on or around the road, and joins the sphere to the surface. Increase B to snow Dharma type.
[0041]
The sphere B can bind the arrangement object E having a predetermined size or less compared to the radius of the sphere B, but the arrangement object E exceeding the predetermined size cannot be combined. In FIG. 2, for example, the cage (E4, E5, E8), the utility pole (E6), the track (E7), etc. cannot be coupled because they are larger than the sphere B. Since an arrangement that cannot be combined becomes an obstacle, the ball B must be enlarged while avoiding it well.
[0042]
The player enlarges the sphere B and joins the arrangement object E having a larger size. At first, it started from the combination of an arrangement E that is about the size of an empty can or a baseball ball, and with the enlargement, it began to combine bicycles, postboxes, buses, etc., and finally combined houses and telephone-sized objects. It grows while destroying the city. And if the sphere B is made a predetermined size or more in time, the stage is cleared. Players can enjoy an unprecedented enjoyment of a sense of destruction full of jokes that develops in extraordinary situations.
[0043]
According to the present embodiment, such various kinds of objects (arrangement E) are bonded to the surface thereof, and the sphere B having irregular irregularities can be easily realized according to the irregularities of the outer shape. can do.
[0044]
[Description of principle]
Next, the principle for realizing the rolling of the sphere B in the present embodiment will be described with reference to FIGS. In the present embodiment, a sphere display model Bd, a motion calculation model Bm, and a sphere collision determination model Bj are prepared for the sphere B. An arrangement object display model Ed and an arrangement object collision determination model Ej are prepared for the arrangement object E.
[0045]
FIG. 3 is a diagram for explaining the handling of the display model.
As shown in FIG. 3A, the sphere B becomes larger while combining the arrangement objects E21 to E24 set on the road surface K in the game space.
[0046]
The sphere display model Bd is modeling data for drawing the appearance of the sphere B on the game screen, and is modeled by polygons, for example, as shown in FIG. A predetermined texture is mapped on the surface to express the appearance of, for example, a snowball or a rubber ball.
[0047]
When the sphere B collides with the arrangement object E, the arrangement object display model Ed of the arrangement object E is coupled to the sphere display model Bd at the collision position H.
For example, in the situation of FIG. 3A, as shown in FIG. 3C, the arrangement object display models Ed21, Ed25, Ed26 are connected to the collision positions H21, H25, H26, respectively, and the ball display model Bd. Combined with The connection relationship between the sphere display model Bd and the arrangement object display model Ed is constituted by, for example, a hierarchical relationship in which the sphere display model Bd is the parent level, the arrangement object display model Ed is the child level, and the collision position is the connection point. Is done. Therefore, after the collision, the sphere B and the arrangement object E are displayed together.
[0048]
FIG. 4 is a diagram for explaining the handling of the motion calculation model.
For example, as shown in FIG. 4B, the motion calculation model Bm has a plurality of displacement points P defined by polar coordinates (R, θ) with the center O1 of the sphere B as the origin, and a rolling reference plane. This is a model for forming S. The rolling of the sphere B is calculated based on the model.
[0049]
Specifically, for example, by obtaining a height from the road surface K of the sphere B with reference to a displacement point close to the current grounding position, it is possible to make the rolling appear to swing up and down. Further, by referring to the inclination of the rolling reference plane S formed by the displacement points adjacent to the ground contact position, the center of gravity position is obtained by obtaining the horizontal slope from the vertical of the straight line connecting the center of the sphere B and the ground contact position. It is possible to make the rolling appear to be shifted to the left and right.
Note that the number of set displacement points P may be set as appropriate. For example, the number of polygons constituting the sphere display model Bd may be set to be smaller than the number of polygons constituting the sphere display model Bd, thereby reducing the calculation load when performing the motion calculation.
[0050]
When the arrangement object E21 newly collides with the sphere B, as shown in FIG. 4B, the motion calculation model Bm corresponds to a portion where the appearance of the sphere B is uneven due to the combination of the arrangement object E21. The position of the displacement point P is changed.
[0051]
  More specifically, as shown in FIG. 4C, a range (in the figure, the projected object display model Ed21 (or the arranged object collision determination model Ej21) in a coupled state is projected onto the motion calculation model Bm. Single pointchainDisplacement points P1 and P2 included in the acute angle region between the lines) are selected. Then, the intersections of the straight line L1 passing through the center O1 and the displacement point P1 and the straight line L2 passing through the center O1 and the displacement point P2 and the combined arrangement display model Ed21 (or the arrangement object collision determination model Ej21) are obtained. It is done.
[0052]
If the intersection point with the arrangement object E21 is obtained for each of the straight lines, as shown in FIG. 4D, the intersection points Q1 and Q2 at the outermost edge from the center O1 are searched from the intersection points, and the polar coordinates are calculated. The radial axis coordinate Rmax is obtained. Next, the radial axis coordinate value R of the displacement points P1 and P2 is reset to R + α × (Rmax−R).
[0053]
In the example of FIG. 4D, the coefficient α is a real number less than 1, and the reset displacement points are more than the apparent unevenness of the spherical display model Bd, such as P1 ′ and P2 ′. Only configured inside. Accordingly, the outermost edge of the sphere B can be rolled while meshing with the road surface K. Of course, the coefficient α may be 1 or more.
[0054]
Therefore, the unevenness of the motion calculation model Bm corresponds to the unevenness of the sphere display model Bd, and it is possible to reproduce the rugged rolling according to the appearance of the sphere B during the motion calculation. Further, by forming the unevenness difference of the motion calculation model Bm to be smaller than the unevenness difference of the sphere display model Bd, even in a state in which the apparent unevenness does not actually roll, It is possible to calculate the movement without any trouble. The displacement point P of the motion calculation model Bm is not limited to a point and may be set as a plane.
[0055]
The sphere collision determination model Bj is a model used in the collision determination process, and is defined as a so-called bounding volume that simplifies the appearance of the sphere display model Bd, for example, as shown in FIG.
[0056]
All objects in the present embodiment are given a set value indicating a size (e.g., corresponding to a physical quantity such as a radius, a representative dimension, a volume, and a weight). When the arrangement object E is combined, for example, as shown in FIG. 5C, the size of the ball collision determination model Bj is equal to the sum of the size of the sphere B and the combined arrangement object E. Thus, the model is updated by the ball collision determination model Bj ′. Accordingly, collision determination according to the size of the sphere B can be easily realized without using the sphere display model Bd composed of a large number of polygons for collision determination.
[0057]
[Description of functional block]
Next, functional blocks for realizing the present embodiment will be described.
FIG. 6 is a block diagram illustrating an example of a functional configuration in the present embodiment. As shown in the figure, the functional blocks constituting the present embodiment include an operation unit 10 for inputting an operation from a player, a processing unit 20 for performing calculations related to control of an apparatus and a game, and a game screen. There is a display unit 30 and a storage unit 40 for storing programs, data, and the like.
[0058]
The operation unit 10 inputs an operation from a player. The operation unit 10 corresponds to the game controllers 1202 and 1204 in FIG. 1, and the function thereof can be realized by hardware such as a cross key, lever, button, joystick, trackball, and the like. An operation input signal output from the operation unit 10 is transmitted to the processing unit 20.
[0059]
The processing unit 20 performs various arithmetic processes such as control of the entire game apparatus, instructions to each functional block in the apparatus, and game calculations.

In addition, the processing unit 20 includes a game calculation unit 22 that performs game calculation processing, and an image generation unit 24 that generates image data from various data obtained by the processing of the game calculation unit 22.
[0060]

When it is determined that the sphere B and the arrangement object E have collided, the display model combining unit 221 determines the collision position based on the positional relationship between the sphere display model Bd and the arrangement object display model Ed, The arrangement object display model Ed is coupled to the sphere display model Bd at the collision position.
[0063]
The motion calculation model setting unit 222 sets the position of the displacement point P of the motion calculation model Bm based on the appearance of the sphere display model Bd.
[0064]
The combination determination unit 223 compares the parameter of the sphere B and the parameter of the arrangement object E, and sets whether the combination with the sphere B is possible for each arrangement object E. Specifically, for example, an arrangement object E arranged within a predetermined radius from the sphere B in the game space is searched and set as a determination target. For example, when the parameter representing the size of the arrangement E is equal to or less than a predetermined value of the parameter representing the size of the sphere B, the combination is allowed.
[0065]
The display model familiarity calculation unit 225 changes the posture of the arrangement object E already coupled to the sphere B so that the unevenness difference decreases as the sphere B moves. As a result, regardless of the posture when the arrangement object E is coupled, when the sphere B is rotated, the overall shape gradually approaches a sphere with small irregularities, and the appearance shape becomes familiar. Specifically, for example, the arrangement object E in the already coupled state is rotated by a predetermined amount around the coupling point in the direction opposite to the rotation direction of the sphere B.
[0066]
The motion calculation model familiarity calculation unit 226 makes the unevenness of the surface of the motion calculation model Bm uniform with the movement of the sphere B, so that the sphere B rolls in the same manner as the familiarity of the sphere display model Bd. Realizes a state where it is easy to roll by adapting to a spherical shape. Specifically, for example, the displacement point P set outside (that is, larger) than the average value of all the displacement points P (average value of the distance from the center O1) is brought closer to the average value. Displace.
[0067]
The collision determination model changing unit 227 enlarges the ball collision determination model Bj of the sphere B by the amount that the arrangement object E is combined with the sphere B and becomes larger. Specifically, for example, the ball collision determination model Bj of the sphere B is expanded to a size equal to the volume sum of the sphere B and the volume of the arrangement object E.

[0076]
The hierarchical information 512 stores hierarchical structure information in which the original model of the sphere B is a parent node (element), the combined arrangement E is a child node, and the collision position H is a connection point.
Therefore, when the collision position between the newly-combined arrangement E and the sphere B (which already has another arrangement E in the combined state) is obtained, the original model of the sphere B and the arrangement display model Ed in the already-connected state are obtained. And where the collision occurred.
[0077]
The motion calculation model information 53 stores modeling data of the motion calculation model Bm shown in FIG.
[0078]
The ball collision determination model information 54 stores modeling data of the ball collision determination model Bj of the sphere B shown in FIG. In the present embodiment, the collision determination model is defined as a so-called bounding volume.
[0079]
The sphere parameter 55 stores the current state quantity of the sphere B and various setting information. Specifically, for example, speed, acceleration, position coordinates, posture information, and information such as radius 551 and volume 552 indicating the size of the sphere B are stored, but may be set as appropriate.
[0080]
The combination history information 57 stores, for example, the identification number 571 of the arrangement object E and the combination point coordinate information 572 in the order of combination with the sphere B.
[0081]
The arrangement object data 60 is set for every object other than the ball B arranged in the game space. The arrangement object data 60 stores arrangement object display model information 61, arrangement object collision determination model information 62, arrangement object parameters 64, and combination determination information 65.
[0082]
The arrangement object display model information 61 stores modeling data of the arrangement object display model Ed. The arrangement object collision determination model information 62 stores modeling data of the arrangement object collision determination model Ej. In the present embodiment, the arrangement object collision determination model Ej is a so-called bounding volume, but its shape may be set as appropriate.
[0083]
As with the sphere parameter 55, the arrangement object parameter 64 stores the state quantity of the arrangement object E and various setting information. Specifically, for example, information on speed, acceleration, position coordinates, posture information, representative dimensions 641 indicating the size of the arrangement E, volume 642, barycentric position coordinates 643, and the like are stored. I do not care.
[0084]
The combination determination information 65 is information indicating whether or not the connection with the sphere B is possible. For example, “1” is stored when the connection is possible, and “0” is displayed when the connection is impossible. The combination determination information 65 is changed by the combination determination unit 223 according to the size of the sphere B.
[0085]
[Description of flow]
Next, a detailed processing flow in the present embodiment will be described with reference to FIGS. The collision determination process, the calculation process for obtaining the position / velocity / acceleration of the object, the drawing process of the game screen, and the like are well-known and will not be described here.
[0086]
FIG. 7 is a flowchart for explaining the flow of processing during the game.
As shown in the figure, when the game is started, a movement operation of the ball B is input from the operation unit 10 (step S102).
[0087]
The game calculation unit 22 calculates the rolling of the sphere B based on the motion calculation model information 53 based on the operation input signal from the operation unit 10, and the image generation unit 24 stores the sphere based on the sphere display model information 51. B is moved and displayed (step S104).
Next, the game calculation unit 22 calculates the motion of the placement object E that is set to move independently in the game space, such as an animal or a vehicle, and the image generation unit 24 stores the motion based on the placement object display model information 61. The arrangement object E is moved and displayed (step S106).
[0088]
If the sphere B and the arrangement object E are moved, the combination determination unit 223 performs the combination determination process for the arrangement object E arranged in a predetermined range centering on the sphere B (step S108).
[0089]
FIG. 8 is a flowchart for explaining the flow of the connection possibility determination process.
As shown in the figure, the combination determination unit 223 first searches the sphere B for an arrangement E having a predetermined radius (step S202). For example, FIG. 14 is a diagram illustrating a state in which the sphere B that travels on the road surrounded by the eaves (E44 to E46) is viewed from directly above. In the case of FIG. 14, the arrangement objects E <b> 41 to E <b> 46 are targets for the combination determination process.
[0090]
Next, the combination determination unit 223 compares the arrangement parameter 64 of the searched arrangement E with the sphere parameter 55, and determines the magnitude relationship between the arrangement E and the sphere B (step S204). For example, when the representative dimension 641 of the arrangement object E is 20% or less of the radius 551 of the sphere B (YES in step S206), it is determined that it can be combined with the sphere B, and “1” is stored in the combination determination information 65 ( Step S208). On the other hand, when the representative dimension 641 is not 20% or less of the radius 551 of the sphere B (NO in step S206), it is determined that the representative dimension 641 is too large to be coupled to the sphere B, and “0” is stored in the coupling determination information 65 (step). S210). When the determination result storage is completed, the flow returns to the flow of FIG.
[0091]
In FIG. 7, the game calculation unit 22 then performs a collision determination based on the ball collision determination model information 54 and the arrangement object collision determination model information 62 (step S <b> 110). When the ball B and the arrangement object E collide (YES in step S112), the game calculation unit 22 refers to the combination determination information 65 of the arrangement object E and determines whether or not the object can be combined with the ball B. (Step S114).
[0092]
When it is determined that the arrangement object E can be combined (YES in step S114), the display model combining unit 221 executes display model combining processing on the sphere B and the arrangement object E (step S116). ).
[0093]
FIG. 9 is a flowchart for explaining the flow of the display model combining process. As shown in the figure, the display model combining unit 221 first refers to the hierarchy information 512 and arranges based on the sphere display model information 51 and the arrangement object display model information 61 of the arrangement object E that has collided. The collision position H of the object E is obtained (step S302).
[0094]
FIG. 15 is a conceptual diagram showing the relationship between the collision positions. FIG. 4A shows a case in which nothing is coupled to the sphere B and the sphere B and the arrangement object E30 collide with each other by a sphere display model Bd and an arrangement object display model Ed30. In this case, the collision position H is H1 on the sphere display model Bd. FIG. 5B shows a case where a plurality of arrangement objects E are already connected to the sphere B, and an arrangement object E30 to be newly combined collides with an already-connected arrangement object E32. In this case, the collision position H is H2 on the arrangement object display model Ed32 of the arrangement object E32.
Therefore, when the sphere B repeats the coupling, the arrangement object E30 to be newly coupled is apparently coupled to the arrangement object E32 in the already coupled state. The collision position information may be a coordinate value in the local coordinate system of the sphere B or a vertex closest to the arrangement object E, and may be defined as appropriate.
[0095]
When the collision position H is obtained, the display model combining unit 221 determines that the original model of the sphere B is the parent level, the newly combined arrangement E is the child level, and the collision position H is the connection point. The information 512 is updated (step S304), and the arrangement history E is newly added to the combination history information 57 to be updated (step S306). When the update is completed, the flow returns to the flow of FIG.
[0096]
Returning to FIG. 7, next, the motion calculation model setting unit 222 executes the motion calculation model setting process, and changes the motion calculation model information 53 according to the changed sphere display model information 51 ( Step S118).
[0097]
FIG. 10 is a flowchart for explaining the flow of the motion calculation model setting process. As shown in the figure, the motion calculation model setting unit 222 first projects an arrangement display model Ed or an arrangement collision determination model Ej of the newly combined arrangement E onto the movement calculation model Bm. A displacement point P included in the range is selected (step S402). That is, the displacement point P is selected in a range where a convex portion is generated when the arrangement object E is combined. For example, in the case of FIG. 4C, the displacement points P1 and P2 are selected.
[0098]
Next, the motion calculation model setting unit 222 obtains a straight line L passing through the selected displacement point P and the center O1 of the sphere B (step S404), and the arrangement display model Ed or the posture coupled to the sphere B or An intersection point with the arrangement object collision determination model Ej is obtained (step S406).
[0099]
When the intersection is found, the motion calculation model setting unit 222 searches for the intersections Q1 and Q2 at the outermost edge from the center 1 among the intersections, as shown in FIG. Thus, the radius axis coordinate Rmax is obtained (step S408). Then, the motion calculation model setting unit 222 resets the radial axis coordinate value R of the displacement points P1 and P2 to R + α × (Rmax−R) (step S410). The motion calculation model setting unit 222 performs the above processing for all the displacement points P selected in step S402 (step S412).
[0100]
Therefore, the motion calculation model Bm forms a rolling reference surface S with less irregularities than the apparent shape (the appearance shape of the sphere display model Bd) as shown in FIG. By calculating the rolling motion of the sphere B based on the motion calculation model Bm, it is possible to achieve a rolling motion that is rugged as it appears, while at the same time being easy to roll according to the game balance. When the setting is completed, the flow returns to the flow of FIG.
[0101]
Returning to FIG. 7, the collision determination model changing unit 227 then changes the ball collision determination model Bj by the amount of the newly combined object E (step S120).
[0102]
FIG. 11 is a flowchart for explaining the flow of the collision determination model changing process. As shown in the figure, the collision determination model changing unit 227 first adds and changes the volume 642 of the newly arranged object E to the volume 552 of the sphere B (step S502). Then, the ball collision determination model Bj is obtained so as to have the same volume as the added volume 552 (step S504), and the ball collision determination model information 54 is updated (step S506). Next, the collision determination model changing unit 227 obtains a spherical radius 551 having a volume equal to the volume 552 after the addition, and updates the sphere parameter 55 (step S508). When the update is completed, the flow returns to the flow of FIG.
[0103]
Returning to FIG. 7, next, the game calculation unit 22 refers to the speed information from the ball parameter 55 to determine whether or not it is currently moving (step S122).
If it is moving (YES in step S122), the display model conforming calculation unit 225 executes the display model conforming process, so that the arrangement object E in the already coupled state is reduced so that the unevenness difference in the appearance of the sphere B is reduced. The joint position and posture of the sphere B are changed so as to adapt the shape of the sphere B (step S124). Then, the motion calculation model familiarity calculation unit 226 executes the motion calculation model familiarity processing, and the motion calculation model Bm Adapt the shape (step S126).
On the other hand, when it is not moving (NO in step S122), in order to prevent the shape from changing even though the ball B is not rolling, the display model conforming process and the motion calculation model conforming process are not executed. .
[0104]
FIG. 12 is a flowchart for explaining the flow of the display model adaptation process. As shown in the figure, the display model familiarity calculation unit 225 first refers to the combination history information 57 and selects a predetermined number of arrangements E in the already combined state according to the reverse combination order (from the newly combined one). (Step S602).
At this time, the display model familiarity calculation unit 225 selects the arrangement object E located at the back of the screen from the center O1 of the sphere B based on the position of the viewpoint (virtual camera) and the position of the sphere B. In other words, the placement object E that is located behind the ball B on the game screen and is virtually invisible to the player is set as the processing target, so that the player cannot see the moment when the posture of the placement object E changes. Further, the number to be selected is limited in order to keep the calculation load related to the processing appropriate.
[0105]
Next, the selected arrangement object E is rotated in the direction opposite to the rotation direction of the sphere B until it collides with another adjacent arrangement object E within a predetermined angle rotation around the coupling point (step S604).
[0106]
Here, for example, as shown in FIG. 16B, as a result of rotating the arrangement object E34 according to the virtual force, the arrangement object E34 comes into contact with another adjacent arrangement object E35 (in step S606). YES), the connection point T and the new contact point T ′ are compared, and a point close to the center of gravity G of the arrangement E is set as the connection point (step S608). Then, the combination position coordinate 572 of the hierarchy information 514 and the combination history information 57 is changed (step S610). The display model familiarity calculation unit 225 performs the same process on all the arrangements E selected in step S602 (step S612), and returns to the flow of FIG.
[0107]
Returning to FIG. 7, next, the motion calculation model familiarity calculation unit 226 changes the position of the displacement point P so that the unevenness difference of the motion calculation model is reduced (step S126).
[0108]
FIG. 13 is a flowchart for explaining the flow of the model calculation process for exercise calculation. As shown in the figure, the motion calculation model familiarity calculation unit 226 first obtains an average value Rave of the radial axis coordinates of all the displacement points P (step S702). Next, the displacement point P located outside the average value Rave is selected (step S704).
[0109]
The motion calculation model familiarity calculation unit 226 changes the radius axis coordinate of the selected displacement point P to R = R− (R−Rave) × γ (step S706). The coefficient γ may be set as appropriate. When the change is completed, the flow returns to the flow of FIG.
[0110]
Returning to FIG. 7, the game calculation unit 22 determines the elapsed time (step S128). If the predetermined time has been reached (YES in step S130), the game is over (step S132). If the predetermined time is not reached (NO in step S130), a stage clear determination is made. If the ball B is larger than the predetermined size and the clear condition is satisfied (YES in step S134), the next stage is entered. Proceed (step S136). If the ball B is not sufficiently large (NO in step S134), the game is continued.

It can be applied to various devices.
[0123]
For example, FIG. 18 is a diagram showing an example when the present invention is applied to the arcade game apparatus 1300. In the arcade game apparatus 1300, a game screen is displayed on the display 1304.

[0128]
[Second Embodiment]
Next, a second embodiment to which the present invention is applied will be described with reference to FIGS. 21 and 22. In the second embodiment, an example will be described in which a process of separating the arrangement object E that has already been combined is executed when the sphere B collides with an obstacle object. Note that the second embodiment can be basically realized by the same constituent elements as those of the first embodiment, and the same elements are denoted by the same reference numerals and the description thereof is omitted.
[0129]
The obstacle object is the arrangement object E that is determined to be uncombinable by the conjoinability determination unit 223. For example, in the example of FIG. 2, the obstacle (E4, E5, E8), the utility pole (E6), the track (E7) ) And the like are larger than the sphere B and cannot be combined and correspond to obstacle objects.
[0130]
In the present embodiment, in the case of NO in step S114 in FIG. 7, the combination release process is executed in the previous stage of step S122 to release the hierarchical relationship between the sphere B and the arrangement object E in the already connected state, thereby A situation is realized in which B collides with an obstacle object and the arrangement object E is separated.
[0131]
[Description of flow]
FIG. 21 is a flowchart for explaining the flow of the combination release process. FIG. 22 is a conceptual diagram illustrating a state in which a sphere collides with an obstacle object and an arrangement object is separated.
[0132]
In the decoupling process, as shown in FIG. 22A, first, the game calculation unit 22 calculates the relative momentum mv with the arrangement E that collides with the ball B (step S802), and the hierarchy is determined according to the relative momentum mv. And the number n of objects to be separated from the sphere B is determined (step S804). Similarly, an angle θ indicating a range for selecting an object to be separated is determined according to the relative momentum mv (step S806).
The number of objects n and the angle θ may be determined in a proportional relationship with the relative momentum mv, or may be determined in a stepwise manner based on the relative momentum mv. I do not care.
[0133]
Next, the display model combining unit 221 determines the collision position H based on the sphere display model Bd and the arrangement object display model Ed (step S808). If the collision position H is obtained, the combination history information 57 is referred to, and the arrangement E in the coupled state that is coupled within the range of the angle axis coordinate ± θ from the collision position H is in the reverse order of coupling. Only a few n are selected (step S810). In the example of FIG. 22A, the number n = 5, and the arrangement object E included in the range of the angle axis coordinates ± θ and to be separated is hatched. Then, the display model combining unit 221 releases the hierarchy of the selected arrangement E, separates it from the sphere B, updates the hierarchy information 512 (step S812), and records the arrangement E separated from the combination history information 57. Is deleted (step S814).
[0134]
As shown in FIG. 22 (b), the game operation unit 22 randomly sets a scattering speed v on the separated arrangement E, and gives the separated arrangement a force due to the impact of the collision (step). S816). As a result, the separated arrangements E are scattered and dropped.
[0135]
Since the object is separated and the sphere display model Bd is changed, the motion calculation model setting unit 222 executes the motion calculation model setting process (see FIG. 10), and the unevenness of the appearance shape of the sphere B is changed. Based on this, the motion calculation model Bm is changed (step S818). The displacement point P to be displaced is a range obtained by projecting the separated arrangement E (at this time, the layer with the sphere B is released but the position is not moved) onto the motion calculation model Bm. Selected from. As a result, it is possible to realize a state in which the place where the combined arrangement E is detached becomes distorted and affects rolling.
[0136]
Next, the collision determination model changing unit 227 subtracts the volume 552 of the sphere B by the volume 642 of the separated arrangement E (step S820). If the volume 552 of the sphere B is updated, the sphere collision determination model Bj is subsequently reduced to a size that is the same as the subtracted volume 644, and the sphere collision determination model information 54 is changed ( Step S822). Then, the collision determination model changing unit 227 calculates the radius of the sphere having the subtracted volume 552, updates the radius 551 (step S824), and returns to the flow of FIG.
[0137]
With the above processing, as shown in FIG. 22C, it is possible to easily realize a state in which the arrangement object E that has been combined due to the impact is removed.
[0138]
The first and second embodiments to which the present invention is applied have been described above. However, the application of the present invention is not limited to these embodiments, and may be changed as appropriate without departing from the gist of the present invention.
[0139]
For example, the motion calculation model Bm is composed of a plurality of displacement points P. However, as shown in FIG. 20A, separate objects F are provided radially from the surface of the original model of the sphere B, and rolling is performed on the end surfaces thereof. A reference plane may be formed. Moreover, as shown in FIG.20 (b), you may comprise by several planes instead of a point.
[0140]
【The invention's effect】
According to the present invention, when the second object collides with the first object, the combining means combines the second object with the first object at the collision position, so that after the collision, the first object and the second object are It can be displayed as a unit.
[0141]
On the other hand, in the first object, a plurality of displacement points are set by the point setting means separately from the display model, and a rolling reference surface is formed. Based on the coupling mode, the displacement point control means appropriately determines the displacement point position and forms the rolling reference plane. Therefore, no matter how complicated the appearance shape of the first and second objects is, it is possible to roll the first object with such a movement corresponding to the appearance shape with a small calculation load.
[0142]
In a game in which another object that collides is attached (attached) on the surface and a character that grows into a snow dharma is rolled and enjoyed, the first object is placed by the player and the second object is placed around If it is applied to the object being made, it can make the character that grows to roll according to the unevenness of its appearance.
