In FIG. 1, a configuration of a terminal device 20 </ b> A that is an example of a configuration of the terminal device 20 is illustrated. The configuration of the game system 100 is not limited to this, and a user terminal device is connected to a server device (video game processing server) via a communication network, and a video game service is provided from the server device to the terminal device. It is good also as a structure provided.

  The game system 100 has various functions for executing a video game in which an object moves in the game space. In the video game of an example of one embodiment of the present invention, a virtual three-dimensional space and a virtual two-dimensional space obtained by two-dimensionalizing the virtual three-dimensional space are configured as a game space. That is, the same game space is formed as a virtual three-dimensional space, and is also formed as a virtual two-dimensional space. The user can play any of these virtual spaces. The virtual two-dimensional space is a horizontal plane space overlooking the virtual three-dimensional space, but is not simply a bird's-eye view, but the height direction information of the virtual three-dimensional space is the horizontal direction of the virtual two-dimensional space. Included as information. The horizontal direction is at least one direction of the horizontal plane direction of the virtual two-dimensional space (horizontal plane space).

  The above-described object can move in the virtual space, and the movement of the object is synchronized between the virtual three-dimensional space and the virtual two-dimensional space. Synchronizing refers to matching the positions of objects in the virtual three-dimensional space and the virtual two-dimensional space, which are the same game space, to the same position. Therefore, even when the game is switched from the virtual 3D space to the virtual 2D space, the object is placed at the position in the virtual 2D space corresponding to the position in the virtual 3D space, so that the game can be continued. .

  The terminal device 20 is managed by a user who plays a video game. For example, a terminal capable of playing a video game such as a stationary game device, a personal computer, a mobile phone terminal, a PDA (Personal Digital Assistants), or a mobile game device. Configured by the device.

  In addition, the terminal device 20 displays an operation device (operation unit) for executing a video game, a storage unit such as an HDD, a control unit configured by a CPU that executes the game and generates a game image, and the game image. Although a display device (display unit) and the like are provided, detailed description thereof is omitted. Further, in the terminal device 20, software (game program) for executing a video game and controlling the progress of the game is stored in the storage unit.

Further, as described above, the two-dimensional space generation information includes the information on the height direction of the virtual three-dimensional space as the information on the horizontal direction.

  The three-dimensional space generation unit 32 generates a virtual three-dimensional space based on the three-dimensional space generation information. The two-dimensional space generation unit 33 generates a virtual two-dimensional space based on the two-dimensional space generation information. Note that generation of each space is a general technique, and thus detailed description thereof is omitted.

  The object control unit 34 controls the movement of the object in the game space and synchronizes the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space. Specifically, the object control unit 34 controls the movement of the object in the virtual three-dimensional space based on the three-dimensional coordinate information. In addition, the movement of the object in the virtual two-dimensional space is calculated from the coordinate information in the horizontal direction of the three-dimensional coordinate information and the information obtained by converting the coordinate information in the height direction of the three-dimensional coordinate information into the coordinate information in the horizontal direction. Control based on dimensional coordinates. That is, the movement of the object in each space is synchronized by converting the three-dimensional coordinates of the virtual three-dimensional space of the current object into the two-dimensional coordinates of the virtual two-dimensional space.

  The horizontal direction when converting the coordinate information in the height direction of the three-dimensional coordinate information of the object is the same as the horizontal direction in which the information in the height direction of the virtual three-dimensional space is included in the two-dimensional space generation information. That is, the movement of the object is synchronized according to the correspondence between the virtual three-dimensional space and the virtual two-dimensional space.

  Next, the operation of the game system 100 (system 100) of this embodiment will be described.

  FIG. 2 is a flowchart illustrating an example of object synchronization processing executed by the system 100. In the object synchronization processing in this example, the synchronization processing of the movement of the object in each space described above is performed. That is, processing for calculating the two-dimensional coordinate information of the object in the virtual two-dimensional space from the three-dimensional coordinate information of the object in the virtual three-dimensional space is performed. Hereinafter, a case where the terminal device 20A executes the object synchronization process will be described as an example.

  The object synchronization process of this example is started in response to the movement of the object, for example.

  In the object synchronization process, the terminal device 20A acquires the three-dimensional coordinate information of the object (step S10). Then, the terminal device 20A converts the height direction information of the three-dimensional coordinate information into horizontal coordinate information, and calculates two-dimensional coordinate information from the converted information and the horizontal information of the three-dimensional coordinate information. Thus, the movement of the object is synchronized (step S11). Thereafter, the terminal device 20A advances the video game based on the calculated coordinate information and the like.

Information on the height direction of the virtual three-dimensional space is included in the virtual two-dimensional space. Moreover, the movement of the object in such virtual three-dimensional space and virtual two-dimensional space can be synchronized. Therefore, the same game can be advanced regardless of which game image in the virtual three-dimensional space and the virtual two-dimensional space is referred to.

  In the example of the first embodiment described above, the terminal device 20A executes the game program to control the progress of the game, but is not particularly limited to this. Instead of the terminal device 20A, the server device may include a spatial information storage unit, a three-dimensional space generation unit, a two-dimensional space generation unit, and an object control unit.

  The server device includes a storage unit such as an HDD (not shown) and a control unit configured by a CPU and the like, and the control unit executes the above-described game program stored in the storage unit, so that the server device is similar to the terminal device 20A. To control the progress of video games. The server device does not execute a video game unlike the terminal device 20A. The server device includes a general configuration for controlling the progress of the video game, such as a control unit and a communication unit, but detailed description thereof is omitted here.

  For example, the server device communicates with a terminal device that has a communication unit and executes a video game via an Internet line (communication network), receives an operation signal from the user (terminal device), and progresses the game. The information regarding is transmitted to the terminal device. A plurality of server devices may cooperate to execute the game program, and the server device and terminal device may cooperate to execute the game program (control the progress of the game).

  FIG. 3 is a flowchart showing an example of the operation on the server device side when the server device executes the object synchronization processing shown in FIG.

  In the object synchronization process, the server device acquires the three-dimensional coordinate information of the object (step S30). Then, the server device converts the height direction information of the three-dimensional coordinate information into horizontal coordinate information, and calculates two-dimensional coordinate information from the converted information and the horizontal information of the three-dimensional coordinate information. Thus, the movement of the object is synchronized (step S31). Thereafter, the server device transmits information for advancing the video game to the user terminal device based on the calculated coordinate information and the like.

  In addition, as an object of the example of the first embodiment described above, for example, there is a player object (character) that can be operated by the user. And what is necessary is just to display the game image of the virtual three-dimensional space and virtual two-dimensional space of the predetermined range centering on a player object on the display apparatus of 20 A of terminal devices.

[Second Embodiment]

In this example, the terminal device 20B includes at least a spatial information storage unit 31B, a three-dimensional space generation unit 32B, a two-dimensional space generation unit 33B, and an object control unit 34B.

  The spatial information storage unit 31B stores 3D space generation information and 2D space generation information. The three-dimensional space generation information includes information for specifying the shape of the space for generating the virtual three-dimensional space. The two-dimensional space generation information includes information for specifying the shape of the space for generating the virtual two-dimensional space. The two-dimensional space generation information includes information on the height direction of the virtual three-dimensional space as horizontal information.

  The three-dimensional space generation unit 32B generates a virtual three-dimensional space based on the three-dimensional space generation information. The two-dimensional space generation unit 33B generates a virtual two-dimensional space based on the two-dimensional space generation information. The object control unit 34B controls the movement of the object in the game space and synchronizes the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space.

  Next, a virtual three-dimensional space and a virtual two-dimensional space that are the same game space will be described with reference to FIGS. 5 (A), 6 (A), and 7 (A) show an example of the virtual three-dimensional space, and FIGS. 5 (B), 6 (B), and 7 (B) are FIGS. An example of a virtual two-dimensional space obtained by two-dimensionalizing the virtual three-dimensional space shown in FIGS.

  In the example of the present embodiment, a virtual three-dimensional space is defined by a coordinate system composed of three axes of X axis, Y axis, and Z axis, and a virtual two-dimensional space is composed of two axes of U axis and V axis. Define in coordinate system. Further, in FIGS. 5 to 7, for convenience of explanation, a grid line is illustrated and one coordinate is expressed by one cell of the grid line and a coordinate value is illustrated, but the grid line is displayed in an actual game image. Not. Furthermore, for the convenience of explanation, the space shown in FIGS. 5 to 7 is given a shaded color, but the color of the space is not particularly limited to this.

  The virtual three-dimensional space is an object of a flat ground 50 having no height as shown in FIG. 5A, an object of plateaus 52 and 54 having a height as shown in FIGS. 6A and 7A, and the like. Formed with. In the virtual two-dimensional space, a virtual three-dimensional space that is a three-dimensional space is formed as a two-dimensional plane (horizontal plane) space. In the example of the present embodiment, the virtual three-dimensional space is two-dimensionalized so that information in the height direction (Y-axis direction) in the virtual three-dimensional space is included as information in the V-axis direction (horizontal direction). .

  The virtual three-dimensional space shown in FIG. Since the flat ground 50 does not include information in the height direction (Y-axis direction), an object of the flat ground 50 'having the same cell shape as shown in FIG. 5B is formed even in the virtual two-dimensional space. That is, the virtual three-dimensional space is two-dimensionalized so that the X-axis coordinates and the U-axis coordinates correspond and the Z-axis coordinates and the V-axis coordinates correspond.

  Further, the virtual three-dimensional space shown in FIG. 6A includes objects of a flat land 51, a plateau 52, and a slope 55. The plateau 52 includes an upright wall surface 52A and an upper surface 52B which is a horizontal surface. The plateau 52 (upper surface 52B) has a level difference (for one cell) with the flat ground 51. In the virtual two-dimensional space shown in FIG. 6 (B), a flat land 51 ′, a plateau 52, and a slope 55 as shown in FIG. Objects are formed.

  The virtual two-dimensional space also includes information on the height direction of the plateau 52 as the wall surface 52A ′. The wall surface 52A ′ represents a step between the flat ground 51 ′ and the plateau 52 ′. Furthermore, information on the height direction of the slope 55 is also included. Information on the height direction of the slope 55 is included as one cell of the slope 55 '. That is, information in the Y-axis direction in the virtual three-dimensional space is two-dimensionalized as information in the V-axis direction in the virtual two-dimensional space. Therefore, when the number of cells in the Z-axis direction in FIG. 6A is compared with the number of cells in the V-axis direction in FIG. 6B, the number of cells in the V-axis direction is larger by a level difference (one cell).

  Next, the virtual three-dimensional space shown in FIG. 7A includes objects of flat land 53, plateau 54, and slope 56. The plateau 54 (upper surface 54B) is three cells higher than the flat land 53, and has a step. The slope 56 is composed of a wall surface 56A and an inclined surface 56B. In the virtual two-dimensional space shown in FIG. 7B, information on the height direction of the plateau 54 is also included as the wall surface 54A ′. Information on the height direction of the slope 56 is also included as the wall surface 56A ′. Therefore, when the number of cells in the Z-axis direction in FIG. 7A and the number of cells in the V-axis direction in FIG. 7B are compared, the number of cells in the V-axis direction is larger by a level difference (for 3 cells).

  Next, synchronization of movement of the object Q (Q ′) will be described with reference to FIGS. The objects Q and Q ′ are the same object, but different reference numerals are used to distinguish them in the three-dimensional virtual space and the virtual two-dimensional space. The object Q (Q ′) is controlled to be movable in the three-dimensional virtual space and the two-dimensional space. The movement of the object Q in the virtual three-dimensional space is controlled based on the three-dimensional coordinate information (x, y, z). The movement of the object Q ′ in the virtual two-dimensional space is controlled based on the two-dimensional coordinate information (u, v) calculated based on the three-dimensional coordinate information (x, y, z).

Specifically, the two-dimensional coordinate information (u, v) is calculated as follows.
u = x (1)
v = y + z (2)

  That is, the coordinate information (y) in the Y-axis direction of the object Q in the virtual three-dimensional space is converted into the coordinate information (v) in the V-axis direction in the virtual two-dimensional space. In equations (1) and (2), (u, v) may be reversed.

  For example, in FIG. 5A, when the object Q moves from the current position (2, 0, 0) to (2, 0, 4), the object Q ′ in FIG. (2,0) to (2,4).

  In FIG. 6A, when the object Q moves from the current position (1, 0, 0) to (1, 1, 3), the object Q ′ in FIG. , 0) to (1, 4).

  Further, in FIG. 7A, when the object Q moves from the current position (4, 0, 1) to (0, 3, 1), the object Q ′ in FIG. , 1) to (0, 4).

  FIG. 8 is a flowchart illustrating an example of object synchronization processing executed by the system 100. In the object synchronization processing in this example, the synchronization processing of the movement of the object Q (Q ′) in each space described above is performed. That is, processing for calculating the two-dimensional coordinate information of the object Q ′ in the virtual two-dimensional space from the three-dimensional coordinate information of the object Q in the virtual three-dimensional space is performed. Hereinafter, a case where the terminal device 20B executes the object synchronization process will be described as an example. Note that the flowchart showing the operation of the server device is omitted from the viewpoint of avoiding repeated explanation.

  The object synchronization process of this example is started in response to the movement of the object Q, for example.

  In the object synchronization process, the terminal device 20B acquires the three-dimensional coordinate information (x, y, z) of the object Q (step S10). Then, the terminal device 20B calculates the two-dimensional coordinate information (u, v) from the three-dimensional coordinate information (x, y, z) using the formulas (1) and (2), whereby the object Q (Q ′) Are synchronized (step S11-B). Thereafter, the terminal device 20B advances the video game based on the calculated coordinate information and the like.

  As described above, as one aspect of the second embodiment, the terminal device 20B includes the spatial information storage unit 31B, the three-dimensional space generation unit 32B, the two-dimensional space generation unit 33B, and the object control unit 34B. Information on the height direction (Y-axis direction) of the virtual three-dimensional space is included in the virtual two-dimensional space. In addition, the movement of the object Q (Q ′) in the virtual three-dimensional space and the virtual two-dimensional space can be synchronized. Therefore, the same game can be advanced regardless of which game image in the virtual three-dimensional space and the virtual two-dimensional space is referred to.

  The object Q (Q ′) in the above-described example of the second embodiment includes, for example, a player object (character) that can be operated by the user. And what is necessary is just to display the game image of the virtual three-dimensional space and virtual two-dimensional space of the predetermined range centering on the player object on the display apparatus of the terminal device 20B.

The two-dimensional space generation unit 33C generates a virtual two-dimensional space based on the two-dimensional space generation information. The object control unit 34C controls the movement of the object in the game space and synchronizes the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space. The object control unit 34C also synchronizes the movement of the object using the scale value Q described above.

Specifically, as in the second embodiment described above, the movement of the object in the virtual three-dimensional space is controlled based on the three-dimensional coordinate information (x, y, z). The movement of the object in the virtual two-dimensional space is controlled based on the two-dimensional coordinate information (u, v) calculated based on the three-dimensional coordinate information (x, y, z). More specifically, using the following formulas (3) and (4) in which the scale value Q is included in the formulas (1) and (2) in the second embodiment, the three-dimensional coordinate information (x , Y, z), the two-dimensional coordinate information (u, v) of the object in the virtual two-dimensional space is calculated.
u = x · Q (3)
v = (y + z) Q (4)

Hereinafter, a case where the terminal device 20C executes the object synchronization process will be described as an example. Note that the flowchart showing the operation of the server device is omitted from the viewpoint of avoiding repeated explanation.

  The object synchronization process of this example is started in response to the movement of the object, for example.

  In the object synchronization process, the terminal device 20C acquires the three-dimensional coordinate information (x, y, z) of the object P (step S10). Then, the terminal device 20C calculates the two-dimensional coordinate information (u, v) from the scale value Q and the three-dimensional coordinate information (x, y, z) using the equations (3) and (4), thereby calculating the object. The movement is synchronized (step S11-C). Thereafter, the terminal device 20C advances the video game based on the calculated coordinate information and the like.

In this example, the terminal device 20D includes at least a spatial information storage unit 31D, a three-dimensional space generation unit 32D, a two-dimensional space generation unit 33D, and an object control unit 34D.

The two-dimensional space generation information includes information on the height direction of the virtual three-dimensional space as horizontal information.

  The spatial information storage unit 31D stores specific area conversion information. The specific area conversion information is referred to when synchronizing the movement of the object when the object is located in the specific area in the virtual three-dimensional space. That is, instead of synchronization based on three-dimensional coordinate information (hereinafter referred to as global synchronization) as in the above-described first to third embodiments, synchronization of object movement using specific area conversion information (hereinafter referred to as special). Synchronization). Note that the position information of the specific region is included in the three-dimensional space generation information and the two-dimensional space generation information.

  The three-dimensional space generation unit 32D generates a virtual three-dimensional space based on the three-dimensional space generation information. The two-dimensional space generation unit 33D generates a virtual two-dimensional space based on the two-dimensional space generation information. The object control unit 34D controls the movement of the object in the game space and synchronizes the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space.

  FIG. 12 is a flowchart illustrating an example of object synchronization processing executed by the system 100. In the object synchronization processing in this example, the synchronization processing of the movement of the object in each space described above is performed. That is, processing for calculating the two-dimensional coordinate information of the object in the virtual two-dimensional space from the three-dimensional coordinate information of the object in the virtual three-dimensional space is performed. Hereinafter, a case where the terminal device 20D executes the object synchronization process will be described as an example. Note that the flowchart showing the operation of the server device is omitted from the viewpoint of avoiding repeated explanation.

  The object synchronization process of this example is started in response to the movement of the object, for example.

  In the object synchronization process, the terminal device 20D acquires the three-dimensional coordinate information of the object (step S10), and determines whether or not the object is located in the specific area (step S10-D). When the object is not located in the specific area (step S10-D: NO), the terminal device 20D uses the height direction information in the three-dimensional coordinate information in the horizontal direction as in the first embodiment described above. Conversion to coordinate information is performed, and global synchronization is performed by calculating two-dimensional coordinate information from the converted information and horizontal information of the three-dimensional coordinate information (step S11).

  On the other hand, when the object is located in the specific area (step S10-D: YES), the terminal device 20D performs special synchronization using the specific area conversion information (step S12-D). For example, the two-dimensional coordinate information is calculated from the three-dimensional coordinate information of the object using the specific area conversion information. Thereafter, the terminal device 20D advances the video game based on the calculated coordinate information and the like.

  As described above, as one aspect of the fourth embodiment, the terminal device 20D includes the spatial information storage unit 31D, the three-dimensional space generation unit 32D, the two-dimensional space generation unit 33D, and the object control unit 34D. In the specific area, the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space can be synchronized.

  Note that examples of the object of the third embodiment described above include a player object (character) that can be operated by the user. And what is necessary is just to display the game image of the virtual three-dimensional space and virtual two-dimensional space of the predetermined range centering on the player object on the display apparatus of terminal device 20D.

  In addition, as the special area in the example of the third embodiment described above, for example, there is an area where an object having a special shape such as a spiral staircase is arranged.

[Fifth Embodiment]
FIG. 13 is a block diagram illustrating a configuration of a terminal device 20 </ b> E that is an example of the terminal device 20. In this example, the terminal device 20E includes at least a spatial information storage unit 31E, a three-dimensional space generation unit 32E, a two-dimensional space generation unit 33E, an object control unit 34E, and a display control unit 35E.

  The spatial information storage unit 31E stores 3D space generation information and 2D space generation information. The three-dimensional space generation information includes information for specifying the shape of the space for generating the virtual three-dimensional space. The two-dimensional space generation information includes information for specifying the shape of the space for generating the virtual two-dimensional space in a state where the virtual three-dimensional space is looked down on. The two-dimensional space generation information includes information on the height direction of the virtual three-dimensional space as horizontal information. The spatial information storage unit 31D stores specific area conversion information.

  The three-dimensional space generation unit 32E generates a virtual three-dimensional space based on the three-dimensional space generation information. The two-dimensional space generation unit 33E generates a virtual two-dimensional space based on the two-dimensional space generation information.

  The object control unit 34E controls the movement of the player object that can be operated by the user (player) and synchronizes the movement of the player object in the virtual three-dimensional space and the virtual two-dimensional space. The player object moves or the like in the game space when the user operates an operation device (operation unit) such as a game pad. The object control unit 34E performs special synchronization when the position of the player object in the virtual three-dimensional space is within the specific area. In addition, when it is outside the specific area, the same synchronization (global synchronization) as in the example of the third embodiment is performed.

  In the example of this embodiment, as in the second and third embodiments described above, the virtual three-dimensional space is defined by a coordinate system composed of three axes of the X axis, the Y axis, and the Z axis, and the virtual two-dimensional space is defined. Defines a coordinate system composed of two axes, U-axis and V-axis. In the global synchronization, the same three-dimensional coordinate information (x, y, z) in the virtual three-dimensional space of the player object is obtained by using the same expressions (3) and (4) as in the third embodiment. ) To calculate the two-dimensional coordinate information (u, v) in the virtual two-dimensional space.

  The display control unit 35E generates a game image of a virtual three-dimensional space and a virtual two-dimensional space with a predetermined range centered on the player object, and displays the game image on the display device (display unit) of the terminal device 20E. In the example of the present embodiment, it is possible to simultaneously display the game images in the virtual three-dimensional space and the virtual two-dimensional space on a display device having two screens, and it is also possible to display either one of the game images. It is. Which display is performed can be set by the user operating the operation unit. The two screens include a configuration in which a single display screen is divided into two display areas and a virtual three-dimensional space and a virtual two-dimensional space game image are simultaneously displayed in each display area.

  The virtual three-dimensional space and the virtual two-dimensional space in the example of the present embodiment are a normal region having the same scale (scale value Q = 1) as shown in FIGS. 5 to 7 and a scale value Q ≠ 1 as shown in FIG. It is composed of a normal area and a specific area 80 as shown in FIG. In the normal area, global synchronization is performed. Further, special synchronization is performed in the specific area. The normal area of the same scale is, for example, an area formed by many objects such as buildings such as towns and human characters. The normal area with the scale value Q ≠ 1 is, for example, a spacious area with relatively few objects such as a desert or a plain. The specific area is an area where an object having a special shape such as a spiral staircase is arranged.

  Hereinafter, the global synchronization of the normal area with the scale value Q ≠ 1 and the special synchronization in the specific area in the player object P (P ′) will be described with reference to FIGS. 14 to 16. In the normal region of the same scale as shown in FIGS. 5 to 7, since the scale value Q = 1, even if the equations (3) and (4) are used, the same results as in the above-described second embodiment are obtained. Become. Therefore, detailed description is omitted. Further, the player objects P and P ′ are the same object, but different reference numerals are used to distinguish them in the three-dimensional virtual space and the virtual two-dimensional space. Further, in FIGS. 14 to 16, for convenience of explanation, a grid line is illustrated and one coordinate is expressed by one cell of the grid line and a coordinate value is illustrated, but the grid line and the like are displayed in an actual game image. Not. Moreover, although the light and dark color is provided to the space shown in FIGS. 14-16 for convenience of explanation, the color of space is not specifically limited to this.

  First, the global synchronization of the normal area with the scale value Q ≠ 1 will be described. FIG. 14A illustrates an example of a virtual three-dimensional space, and FIG. 14B illustrates an example of a virtual two-dimensional space obtained by two-dimensionalizing the virtual three-dimensional space illustrated in FIG. Note that FIG. 14A illustrates a state in which a virtual three-dimensional space is looked down for convenience of explanation. 14A and 14B, five cells in the virtual three-dimensional space correspond to one cell in the virtual two-dimensional space. That is, 5 cells × 5 cells in the virtual three-dimensional space correspond to 1 cell × 1 cell in the virtual two-dimensional space. Therefore, in the example of the present embodiment, the scale value Q = 1/5.

  For example, in FIG. 14A, when the player object P moves from the current position (12, 0, 12) to (12, 0, 15), the object P ′ in FIG. Move from (2,2) to (2,3). Note that the numbers after the decimal point are rounded down. Therefore, for example, when the player object P moves from the current position (12, 0, 12) to (12, 0, 14), the object P ′ remains at the current position (2, 2).

  Next, special synchronization in a specific area will be described. FIG. 15A shows an example of a virtual three-dimensional space, and FIG. 15B shows an example of a virtual two-dimensional space obtained by two-dimensionalizing the virtual three-dimensional space shown in FIG. Note that FIG. 15A shows a state in which a virtual three-dimensional space is looked down for convenience of explanation. 16A and 16B are virtual spaces similar to FIGS. 15A and 15B, but the specific area 80 is illustrated.

  In the virtual three-dimensional space shown in FIG. 15A, an object of the castle 70, semi-circular staircases 71A and 71B connected to the entrance of the castle 70, and a flat ground 72 are arranged. When entering the castle 70, the player object P must move up the stairs 71A or 71B from the flat ground 72 to the entrance. In the virtual two-dimensional space shown in FIG. 15 (B), a castle 70 ′, staircases 71A ′ and 71B ′, and a flat ground 72 ′ in which the castle 70 and the like are two-dimensionalized are arranged.

  In the example of the present embodiment, a region including the tread portion of the stairs 71A, 71B, 71A ′, 71B ′ is set as a special region. In FIG. 17, only specific areas 80 and 80 ′ for the stairs 71A and 71A ′ are shown. The specific areas for the stairs 71B and 71B ′ have the same shape. Further, the position information of the specific region is included in the 3D space generation information and the 2D space generation information.

  The specific areas 80 and 80 'are subdivided into a plurality of sections A to O and A' to O '. The specific area conversion information includes section information such as position information of each section A to O and A ′ to O ′, and information that associates the sections A to O with the sections A ′ to O ′. In the example of the present embodiment, for example, the sections with the same alphabet such as section A and section A ′ are associated one-to-one. The movement of the player object P (P ′) is synchronized based on the correspondence relationship of the divisions. For example, when the player object P in the virtual three-dimensional space moves from the section L to the section K, the player object P ′ in the virtual two-dimensional space also moves from the section L ′ to the section K ′.

  Specifically, based on the three-dimensional coordinate information (x, y, z) of the player object P, the section of the specific region 80 of the virtual three-dimensional space to which the player object P belongs is specified, and the virtual two-dimensional space corresponding to this section is identified. The two-dimensional coordinate information is calculated by specifying the section of the specific region 80 ′. In the specific areas 80 and 80 ′, the position of the player object P (P ′) may be positioned at the center (coordinates) of the division, for example. In the case of the specific regions 80 and 80 ', the scales of the virtual three-dimensional space and the virtual two-dimensional space need not be considered.

  In the example of the present embodiment, the sections A, I, and M (A ′, I ′, M ′) are set as areas where the player object P (P ′) cannot move. Further, in the example of the present embodiment, the number of specific areas in the virtual three-dimensional space and the virtual two-dimensional space is the same, but the correspondence relationship between the virtual three-dimensional space and the virtual two-dimensional space If the number is set, the number of sections may be different. The shape of the section is not limited to a quadrilateral. Furthermore, it is desirable that the section of the specific area in the virtual two-dimensional space matches the cell.

  FIG. 17 is a flowchart illustrating an example of object synchronization processing executed by the system 100. In the object synchronization processing in this example, the synchronization processing of the movement of the player object P (P ′) in each space described above is performed. That is, processing for calculating the two-dimensional coordinate information of the player object P ′ in the virtual two-dimensional space from the three-dimensional coordinate information of the player object P in the virtual three-dimensional space is performed. Hereinafter, a case where the terminal device 20E executes the object synchronization process will be described as an example. Note that the flowchart showing the operation of the server device is omitted from the viewpoint of avoiding repeated explanation.

  The object synchronization process of this example is started in response to the movement of the player object P, for example.

  In the object synchronization process, the terminal device 20E acquires the three-dimensional coordinate information (x, y, z) of the player object P (step S10), and determines whether or not the player object P is located in the specific area (step S10). Step S10-D). When the player object P is not located in the specific area (step S10-D: NO), the terminal device 20E uses the expressions (3) and (4) to calculate the scale value Q and the three-dimensional coordinate information (x, y, Global synchronization for calculating the two-dimensional coordinate information (u, v) from z) is performed (step S11-E).

  On the other hand, when the player object P is located in the specific area (step S10-D: YES), the terminal device 20E uses the specific area conversion information to obtain the three-dimensional coordinate information (x, y, z) of the player object P. 2D coordinate information (u, v) is calculated from (step S12-E). Thereafter, the terminal device 20E advances the video game based on the calculated coordinate information and the like.

  As described above, as one aspect of the fifth embodiment, the terminal device 20E includes the spatial information storage unit 31E, the three-dimensional space generation unit 32E, the two-dimensional space generation unit 33E, the object control unit 34E, and the display control unit 35E. Since the configuration is provided, it is possible to synchronize the movement of the object in the virtual three-dimensional space and the virtual two-dimensional space in the normal region and the specific region in consideration of the scale. Therefore, the same game can be advanced even if any game image in the virtual three-dimensional space and the virtual two-dimensional space including the normal region and the special region is referred to.

  In addition, since the display of game images in the virtual 3D space and the virtual 2D space can be changed according to the user's operation, only the game image in the virtual 2D space is displayed according to the user's mood and preferences. It is possible to play and play by displaying game images in both the virtual three-dimensional space and the virtual two-dimensional space. In addition, since the movement of the player object is synchronized, even if the game image in the virtual three-dimensional space is displayed and the game image is switched to display the game image in the virtual two-dimensional space, the game is played from the state immediately before the switching. Can continue.

  Note that the concept of the player object P (P ′) in the example of the present embodiment includes various objects that can be operated by the user, such as characters, avatars, and fighters. Further, game data such as image data for generating the player object P (P ′) is also included in the game program. In addition, the specific area in the example of the present embodiment is not limited to the staircase object, and may be set as appropriate according to the configuration of the game space.

  Finally, in the example of each embodiment described above, the movement of the object is synchronized by calculating the two-dimensional coordinate information based on the three-dimensional coordinate information of the object in the virtual three-dimensional space. You may make it synchronize by calculating three-dimensional coordinate information based on the two-dimensional coordinate information of the object in a three-dimensional space. Specifically, the processing procedure for calculating the two-dimensional coordinate information based on the three-dimensional coordinate information of the object in the virtual three-dimensional space may be performed in reverse. For example, in the case of global synchronization, grid lines are provided in the virtual three-dimensional space and the virtual two-dimensional space, and the object is moved to the square in the virtual three-dimensional space where the object moves in the virtual two-dimensional space. The grid lines provided in the virtual three-dimensional space and the virtual two-dimensional space have the same number of cells and the ratio of the vertical and horizontal cells. Note that the shape and size of the cells may be different between the virtual three-dimensional space and the virtual two-dimensional space. The special synchronization may be performed in the reverse order. For example, in FIG. 16, when the player object P ′ in the virtual two-dimensional space moves from the section L ′ to the section K ′, the player object P in the virtual three-dimensional space also moves from the section L to the section K. Good.
