Description

  The present invention relates to a program, a method, an electronic apparatus, and a system for displaying an object image in a game.

  There is known a game such as a miniature garden game in which a player performs an operation such as changing the arrangement of objects arranged in a virtual space. In such a game, a technique called quarter view, which is a method of two-dimensionally drawing a three-dimensional space from an overhead viewpoint, is generally used. Fixed quarter views, which limit the viewpoint only from a specific direction, are widely adopted because they can be implemented using relatively few hardware resources.

  In this way, when using a method for representing a three-dimensional space in a two-dimensional manner from a predetermined viewpoint, an object arranged in the front direction of the screen covers an object group arranged in the depth direction of the screen ( occlusion) occurs. In particular, when the viewpoint is limited to only from a specific direction as in the fixed quarter view, the player cannot visually recognize the object covered by the object in front. In Patent Document 1, as one of the techniques for solving this occlusion problem, an object placed in the back is projected onto a front object in a planar manner to change the color (texture, etc.) of a part of the front object. A configuration is disclosed in which the player recognizes the presence of an object in the back.

Japanese Patent Laid-Open No. 2005-322085

  In the configuration described in Patent Document 1, even if the player can recognize the presence of the back object, it is difficult to operate the back object hidden by the near object.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The game system according to the present embodiment can be realized by a system in which a plurality of electronic devices are connected via a network, but can also be realized by a single electronic device. First, an embodiment realized by one electronic device will be described, and then a system connected to a network will be described.

[First Embodiment]
Hereinafter, an embodiment realized by a single electronic device will be described. The electronic device 100 in the present embodiment is a device that controls the execution of a game, and receives an operation input from a player through a touch panel. For example, a portable device such as a smartphone, a tablet terminal, or a portable game machine can be used. It is also apparent that the present invention can be implemented as a stationary device such as a PC or a game-dedicated machine that accepts a player's operation input from a mouse or controller instead of the touch panel.

  The processing unit 101 performs various processing such as game processing and image generation processing based on the program 106, input data from the input unit 103, or data received from the communication unit 105. The processing unit 101 includes a processor that controls each unit included in the electronic apparatus 100, and performs various processes using a register included in the processor and the storage unit 104 as a work area. Each of these components is connected by the bus 108, but each may be individually connected as necessary.

  The display unit (display) 102 displays a game screen according to the progress of the game and the player operation in accordance with the control of the processing unit 101. A liquid crystal display is preferable, but a display using an organic EL, a plasma display, or the like may be used.

  The storage unit 104 includes a hard disk, a main memory, and a buffer memory. A program 106 is stored in the hard disk. However, the hard disk may be any nonvolatile storage or nonvolatile memory as long as it can store information, and may be removable. For example, when the electronic device 100 is a smartphone, it includes ROM and RAM. The storage unit 104 stores the program 106 and various types of data that can be referred to when the program is executed. The program 106 includes a program for any application that requires player input such as an operating system or a video game, a web browser, etc., and various data for displaying various images such as objects appearing in the game, for example. The image data, the position of the object, and data that can be written in the storage unit 104 during the game are also included.

  The communication unit 105 performs mobile communication, wireless communication such as wireless LAN, and wired communication using an Ethernet (registered trademark) cable, a USB cable, or the like. The communication unit 105 can also download the program from the server and store it in the storage unit 104. The program may be downloaded from the server via the communication unit 105 and stored in the storage unit 104. The program may be stored in an optical disk such as a CD / DVD, an optical drive may be connected to the communication unit 105, and the program or the like may be read from the optical disk and stored in the storage unit 104.

  The input unit 103 has a function of receiving input from the user, such as a touch panel, a touch pad, a keyboard, a mouse, or a game controller. The input unit 103 is preferably a contact type input unit that gives an input to the electronic apparatus 100 based on a position touched by the player, such as a touch panel. When the electronic device 100 includes the touch panel 110 as the input unit 103, the touch panel 110 also functions as the display unit 102, and the display unit 102 and the input unit 103 have an integrated structure. In this case, the touch panel 110 receives an input by a player's touch on the display unit 102 (input unit 103), detects coordinates corresponding to a position touched by the player, and provides the electronic device 100 with the coordinates. The detection method may include any method such as a capacitance method. Although the display unit 102 and the input unit 103 may be in separate forms arranged at different positions, in the present embodiment, the electronic apparatus 100 including the touch panel 110 will be mainly described.

  Here, the touch is an operation or a state in which a finger or the like touches the touch panel 110. Note that although the touch by the player is described as being performed by the player's finger, the touch may be performed by any finger, or may be another such as a stylus pen. On the other hand, the release is an operation or state in which a finger or the like is separated from the touch panel. The player mainly operates by touching or releasing the touch panel 110. Such touch operations may include touch, long touch, multi-touch, release, slide, swipe, tap, double tap, long tap, drag, and flick. For example, the slide is an operation of moving the touch position while a finger or the like is in contact with the touch panel.

  The touch panel 110 is designated by coordinates using a coordinate plane composed of a first axis and a second axis substantially orthogonal to the first axis. Preferably, as illustrated in FIG. 2, the first axis is substantially rectangular and the short side of the touch panel 110 and the second axis are substantially parallel to the long side of the touch panel 110, and the first axis direction coordinate axis ( The horizontal axis) and the coordinate axis (vertical axis) in the second axis direction are represented as coordinates (x, y). The processing unit 101 can acquire a touch position detected by the touch panel 110 as the coordinate (x, y) data using a program or the like. For example, when the detection accuracy of the touch panel 110 is 640 dots × 1,136 dots, the resolution can be 640 dots in the horizontal axis direction and 1,136 dots in the vertical axis direction. In this case, the dot may be a single point or a certain region (cell). However, it should be noted that the distance between the dots is usually different for each touch panel (electronic device). Note that the coordinate setting shown in FIG. 2 is an example of this, and the coordinate axes can be set by a program. Also, polar coordinates can be set, and other coordinate systems can be set by coordinate conversion. In the case where the display unit 102 and the input unit 103 are arranged in different positions, coordinates are set in the input unit 103 as described above, and the display unit 102 corresponds to the coordinates of the input unit 103. You can set the coordinates.

  FIG. 3 shows an example of a functional block diagram of the electronic device 100 of the present invention. The electronic device 100 includes a touch detection unit 301, a display unit 302, a visible region determination unit 303, a display image generation unit 304, a player operation processing unit 305, a storage unit 306, and a communication unit 307.

  The touch detection unit 301 has a function of detecting a touch position and a touch operation by the player on the touch panel 110. The display unit 302 displays a game image such as a visible region operation image and an object operation image. The visible region operation image is for causing the player to operate the position of the visible region in the virtual space of the game, and expresses at least a part of the virtual space. A visible area display indicating a predetermined visible area is displayed in the visible area operation image, and the player can move the visible area by moving the visible area display. The object operation image is for causing the player to operate an object arranged in the virtual space, and is an image obtained by viewing at least a part of the other area of the virtual space from the virtual camera.

  The visible region determining means 303 determines a predetermined visible region, and then when the visible region display displayed in the visible region operation image is moved by the player, the virtual region corresponding to the movement destination position on the visible region operation image is displayed. Change the visible area to the area in space.

  The display image generation unit 304 generates a visible region operation image and an object operation image to be displayed on the display unit 302. When generating an object operation image, a visualization process is performed on an object placed in the visible region based on position information of the object placed in the virtual space, and an object placed outside the visible region is executed. The display object image is generated by executing the invisibility processing, and the object operation image including the object image is generated by arranging the display object image at the corresponding position of the object operation image. If the object operation image already includes the display object image, the object operation image is updated and displayed using the newly generated display object image instead of the already included display object image. The visualization process is a process for displaying the object so that the player can visually recognize the object, and the invisibility process is a process for hiding the object so that the player cannot recognize the object. Further, the invisible process may be in a form such as a transparent process that allows the player to recognize that the display is different from the normal display. The invisible process preferably further includes a process of invalidating an operation on the object by the player. The visualization process preferably includes a process for validating an operation on the object.

  The player operation processing unit 305 determines and processes what player operation has been performed based on the input from the touch detection unit 301 and other information. The storage unit 306 has a function of storing data such as virtual space information and object information. The communication unit 307 has a function of transmitting / receiving information to / from other devices. In the present embodiment, these functions are realized by executing the program 106 included in the hardware configuration shown in FIG. 1, but by configuring an electronic circuit or the like for realizing each function. It can also be realized by hardware.

  FIG. 4 shows a game screen 400 as one embodiment of the present invention. The game in the present embodiment is a game in which a player places and moves an object expressed as a building such as a building in a virtual space at an arbitrary position. On the game screen 400, the visible region operation image 401 is superimposed on the object operation image 451 and displayed. Preferably, the object operation image 451 is displayed larger than the visible region operation image 401. The visible region operation image 401 and the object operation image 451 may be displayed side by side without being superimposed. For example, when the electronic apparatus 100 has two separate display units, the visible region operation image 401 and the object operation image 451 may be displayed separately on the respective display units. The visible region operation image 401 is an overhead view of the entire virtual space, but may be, for example, a two-dimensional map looking down from the vertical direction, or showing only the shape of the virtual space that does not include objects or the like. . Moreover, although it may show only a part of the virtual space instead of the whole, it is preferable to express an area wider than the area expressed by the object operation image. The position in the virtual space can be specified by XYZ coordinates. In FIG. 4, the lower left solid line 403 indicating the virtual space is shown as the X axis, the lower right solid line 404 is shown as the Y axis, and lines (grid lines) parallel to these axes are shown by dotted lines. Although the Z-axis is not displayed, it may be displayed. The same display is performed on the object operation image 451.

In the visible region operation image 401, an image 402 and a visible region display 405 when the entire virtual space is viewed from a predetermined camera position are displayed. The visible region display 405 is displayed as a square frame, and the outside of the frame is displayed with the color tone lowered, thereby clarifying the distinction between the visible region and the invisible region. The visible region display 405 is not limited to a square frame, and may be a circular shape or may be changed by an operation of the player. In order to distinguish between the visible region and the invisible region, it is not necessary to make a color difference.

  The visible region operation image 401 displays a fixed background object 406 and operation target objects 407 and 408. The fixed background object is an object that cannot be operated by a player such as a river or a mountain and does not move autonomously. The operation target object is, for example, a building such as a building or a stadium, and is an object that can be arranged and moved by a player. The fixed background object and the operation target object are displayed regardless of whether they are inside or outside the visible region, but the portion outside the visible region is displayed with the color tone lowered.

In the object operation image 451, a background object 455 that moves autonomously in addition to the operation target object 453 and the fixed background object 454 is displayed. The moving background object 455 cannot be operated by the player. Further, a visible area display 452 is displayed at a position corresponding to the visible area. Only the object arranged in the visible area is displayed as the object image, and the object arranged in the outer area is not displayed. By displaying a colored flat panel 456 at a position where the operation target objects 407 and 408 that have been hidden are arranged, it is indicated that the object that has been made invisible is arranged. The operation target object 407 arranged across the inside and outside of the visible region is invisible including the portion arranged inside, and the flat panel 456 is displayed. Due to such processing, the object 453 obscured by the object 407 in the visible region operation image 401 is displayed in the object operation image 451 and can be confirmed and operated by the player.

  As shown in FIG. 5A, the visible region operation image 401 in the present embodiment is formed by superimposing three image layers: a base layer 500, an object layer 501, and a visible region display layer 502. The base layer 500 is a layer that is a base for a display image, and includes XY coordinate axes and grid lines. The object layer is a layer including a display object image, and is divided into a fixed background object layer 503 and an operation target object layer 504. The fixed background object layer 503 includes an image for the fixed background object 406. The operation target object layer 504 is a layer including object images 407 and 408 to be operated. The visible area display layer 502 is a layer including the visible area display 405. In addition, by setting the outside of the visible region to a semi-transparent gray, the tone of the color outside the visible region can be lowered and displayed.

  Further, as shown in FIG. 5B, the object operation image 451 in the present embodiment is also formed by superimposing three image layers of the base layer 550, the object layer 551, and the visible region display layer 552. The object layer 551 here includes a moving background object layer 554 in addition to the fixed background object layer 553 and the operation target object layer 555. The moving background object layer 554 includes an image for the moving background object 455. In the object layer 551, only the object image arranged in the visible region is displayed, and the invisible processing is performed for the object outside the visible region. For an operation target object that has been made invisible, a colored flat panel 456 is disposed at the position of the object.

  In each layer, the object image to be displayed and the visible region display are arranged at the position of each layer corresponding to the arrangement position of the virtual space based on the object information or the like. When the object image to be displayed is changed by a player operation or the like, a layer to be updated is generated again, the corresponding layer of the visible region operation image and the object operation image is updated, and the visible region operation image and the object are updated. Update the operation image. All layers may be regenerated and updated.

  In the present embodiment, as described above, processing is performed by dividing into a plurality of image layers. However, the structure of the layers is not limited to this, and other forms may be used. Further, all object images and the like may be processed collectively regardless of the layer structure.

  Next, the operation of the electronic apparatus 100 in the present embodiment will be described using the flowchart shown in FIG. First, in step 601, the visible region determining unit 303 determines the position, size, shape, and the like of the visible region in the virtual space based on the visible region information as the initial value stored in the storage unit 306.

  Next, in step 603, the display image generation unit 304 generates a visible region operation image 401. As described above, the visible region operation image 401 is formed by the base layer 500, the object layer 501, and the visible region display layer 502. For the base layer 500, a predetermined image stored in the storage unit 306 is acquired and used as the base layer 501. The base layer image in the present embodiment is an image when the cubic virtual space is viewed from a predetermined camera position. When the visible region operation image 401 is an image representing a part of the virtual space, a base layer of a partial region to be displayed is generated based on the entire base layer image acquired from the storage unit 306. Further, the visible region operation image may be generated by calculation based on virtual space information that defines the virtual space, such as the size and shape of the virtual space.

  Next, the object layer 501 is generated. The object layer 501 includes a fixed background object layer 503 and an operation target object layer 504. Based on the object information, the display image generation unit 304 arranges the image of the fixed background object at the position of the fixed background object layer 503 corresponding to the position of the object in the virtual space, and corresponds the image of the operation target object to the position of the object. It is arranged at the position of the operation target object layer 503 to be operated. The object information includes information such as the object image, position, and object type (fixed background object, moving background object, operation target object). The display image generation unit 304 further generates a visible area display layer 502 based on the information about the determined visible area. The visible area display layer 502 includes a visible area display 405, and the outside of the visible area is a semi-transparent gray.

  The display image generation unit 304 generates a visible region operation image 401 by superimposing the generated base layer 500, object layer 501, and visible region display layer 502.

  In step 605, the display image generation unit 304 generates an object operation image 451. The base layer 550, the object layer 551, and the visible region display layer 552 are formed. In this embodiment, a part of the background layer image of the entire virtual space stored in the storage unit 306 is set as the background layer 550, but the virtual space such as a predetermined camera position, the size of the virtual space, and the shape is defined. The object operation image may be generated by calculation based on the information to be performed.

  The display image generation unit 304 generates an object layer as an object image to be displayed based on the determined visible region and object information. The object layer 550 includes a fixed background object layer 553, a moving background object layer 554, and an operation target object layer 555.

  The display image generation unit 304 determines whether or not each operation target object is arranged in the visible area based on the determined visible area and the position information of the object, and for the object arranged in the visible area Then, the visualization process is performed on the object. Specifically, the player operation on the object is validated, and an object image representing the object is set as a drawing process target and is arranged at the position of the operation target object layer 555 corresponding to the object position. For objects placed outside the visible region or across the visible region, an invisible process is performed. Specifically, the player operation on the object is invalidated, the object image representing the object is temporarily excluded from the drawing process, and the flat panel colored on the layer of the operation target object 555 corresponding to the object position is displayed. indicate.

  Similarly, whether or not the fixed background object and the moving background object are arranged in the visible region is determined, and for the object arranged in the visible region, the object is visualized. However, since the background object is not subject to the player operation, the setting for enabling / disabling the player operation is not performed. Further, a colored flat panel is not displayed at the position of the object arranged in the invisible region. When the moving background object is invisible, the moving background object is excluded from the drawing process target. Therefore, the process of moving the image of the object is invalidated while maintaining the state at that time. By these processes, a fixed background object layer 503 and a moving background object layer 504 are generated. The display image generation unit 304 further generates a visible area display layer 552 based on the information about the determined visible area. The visible area display layer 552 includes a visible area display 452, and the outside of the visible area is a semi-transparent gray.

  The display image generation unit 304 generates the object operation image 451 by superimposing the generated base layer 550, object layer 551, and visible region display layer 552.

  In step 607, the visible region operation image 401 and the object operation image 451 are displayed on the display unit 302.

  Next, the electronic device 100 performs a visible region movement process, an object movement process, and an object image movement process based on the player operation (steps 611 to 635). First, in step 611, when the touch detection unit 301 detects a touch operation on the touch panel 110 by the player, this is output to the player input processing unit 305. Based on this, the player input processing means 305 determines whether or not the player has performed a visible region moving operation. For example, as shown in FIG. 7A, when the player touches and slides on the visible region display 705 in the visible region operation image 701 displayed on the touch panel 110 (touch detection unit 301 and display unit 302). The touch detection unit 301 detects a slide input including the slide start position. Based on the detected slide input information and display position information on the touch panel 110 of the visible area display 705, the player input processing means 305 confirms that this input is a slide operation of the visible area display 705 in the visible area operation image. Determination is made (step 611). Then, the visible region determining unit 303 moves the visible region to the region in the virtual space corresponding to the movement destination position of the visible region display 705 displayed in the visible region operation image 701, and the display image generating unit 304 is changed. Based on the visible area information, the visible area display layers 502 and 552 are regenerated (step 613).

  In step 615, the display image generation unit 304 generates the object image to be displayed again based on the changed visible region and object information. Before moving to the visible area, the object was placed outside the visible area, but the object that was in the visible area by moving the visible area was visualized, and it was in the visible area before moving the visible area. However, invisibility processing is performed for objects that are outside the visible region. By these visualization / invisibility processes, a new object layer is generated as a new display object image. Then, the visible region operation image 450 and the object operation image 451 are updated and displayed using the newly generated layer instead of the layer before the visible region movement (step 617).

  Based on the input from the touch detection unit 301, the player input processing unit 305 determines whether or not the player's slide operation on the visible region display 702 has ended (step 619). For example, when it is detected that the touch on the touch panel 110 by the player has been released, it is determined that the slide operation has ended, and the visible region moving process ends. When the slide operation is continued, the process returns to step 613, and the visible area is sequentially updated based on the slide position, and the visible area operation image and the object operation image are updated.

  As a result of the processing from step 611 to step 619, the visible area display 702 is moved in the upward direction on the screen by the player operation on the visible area display 702 on the visible area operation image 701 as shown in FIG. The visible region display 752 is also moved upward on the screen. Accordingly, the object 455 that has been displayed so far is hidden and the object 753 is displayed.

  Next, the player input processing unit 305 determines whether or not a player input for an object moving operation has been performed based on the input from the touch detection unit 301 (step 621). As shown in FIG. 7B, when the player touches and slides the object image 760 in the object operation image 751 displayed on the display unit 302 in the upper right direction of the screen, the touch detection unit 301 causes the slide. Detect input. Based on the detected slide input information and object position information, the player input processing means 305 determines that this input is a slide operation on the object 760 on the object operation image 751 (step 621). Then, the player input processing unit 305 updates the position information of the object stored in the storage unit 306 based on the movement destination position (step 623). The display image generation unit 304 performs invisibility processing if the movement destination position is outside the visible region, and if it is within the visible region, arranges the image of the object at the movement destination position and generates an updated object layer. And displayed on the object operation image 751 (step 625). In FIG. 7B, since the movement is within the visible region, the object 760 is displayed at the movement destination position. Such an operation of the object may be not only a movement process for changing the position of the object but also an operation for changing the direction of the object.

  Based on the input from the touch detection unit 301, the player input processing unit 305 determines whether or not the player's slide operation on the object 760 has ended (step 627). For example, when it is detected that the touch on the touch panel 110 by the player has been released, it is determined that the slide operation has ended. If the slide operation continues, the process returns to step 623 to update the object operation image 751 by sequentially updating the object position based on the slide position. When the slide operation is completed, the operation target object layer for the visible region operation image 701 is updated and displayed based on the position of the object at that time (step 629). As described above, during the object moving operation, the object operation image is sequentially updated and displayed, but it is preferable that the visible region operation image is updated and displayed only after the moving operation is completed. .

  Next, in steps 631 to 635, an object operation image moving operation process is executed. As shown in FIG. 7C, when the player slides the object operation image 751, the position of the virtual camera can be changed and the area displayed on the object operation image 751 can be changed. For example, when the player touches and slides on a position where no operation target object is displayed in the object operation image 701 displayed on the touch panel, the touch detection unit 301 detects the touch position, movement direction, and movement amount. And output to the player input processing means 305. Based on the information, the object information, and the like, the player input processing unit 305 determines that the movement operation input of the object operation image 751 has been performed (step 631). Based on the moving direction and moving amount, the display image generating unit 304 generates a fixed background object layer, a moving background object layer, and an operation target object layer in the moved area, and displays the updated object operation image. (Step 633). At this time, since the position of the visible area in the virtual space is not changed, the visible area display is also moved and displayed as the display area of the object operation image is moved.

  Based on the input from the touch detection unit 301, the player input processing unit 305 determines whether or not the player's slide operation on the object operation image 751 has ended (step 635). If the slide operation is continued, the process returns to step 633, and if the slide operation is completed, the process returns to step 611.

  As described above, according to the present invention, it is possible to cause an object operation to be easily performed by causing the player to display only an object in an area of interest on the object operation image by performing an operation on the visible area display on the visible area operation image. The position of the visible region in the object operation image is not fixed at a predetermined position on the display screen, and can be freely moved by an operation on the visible region operation image. It is not necessary to move the display area of the object operation image in order to move the visible area. Therefore, the player can move only the visible region in the object operation image by displaying the region of interest on the object operation image and performing only the visible region display on the visible region operation image. In addition, since the movement of the object operation image does not move the visible region, the display region of the object operation image can be moved while the position of the visible region in the virtual space is fixed. Furthermore, in the visible area display, since an image representing a relatively wide range can be displayed, the visible area can be selected while viewing the entire virtual space, and in the object operation image, the area that the player is paying attention to Can be displayed in detail.

  In the present embodiment, the object placed across the visible region is subjected to the invisibility process for the entire object. However, as shown in FIG. 8A, the object is placed in the visible region. The portion 860 may be visualized, and the portion 861 arranged outside the visible region may be invisible. Such a process can be realized, for example, by forming one object with a plurality of partial objects and executing a visualization / invisibility process for each partial object. The operation validation / invalidation process is preferably performed on the entire object.

  Further, in the present embodiment, as an example of the invisibility process, an example in which an object is not displayed has been described, but a transparent process may be used as shown in FIG. The object 871 hidden behind the object 870 can also be visually recognized by the transparency process. It is preferable to perform a process of invalidating an operation such as selection by the player for the object that has been subjected to the transparent process. It is possible to easily operate an object arranged behind the transparently processed object by a touch operation or the like. Further, when an object outside the visible area is moved into the visible area due to the movement of the visible area, the transparency process for the object is terminated and the player operation is validated to execute the visualization process. be able to.

  As shown in FIG. 8C, two or more visible regions 802 and 880 may be used. It is possible to examine and manipulate the arrangement of objects while simultaneously confirming objects arranged in two or more distant areas. For example, in a game for urban development, when it is desired to simultaneously develop two stations that are geographically separated but connected as a route, the related development is facilitated strategically. Further, when it is desired to place a trap for the opponent of the game at a remote location on the opponent's route, it is also possible to strategically arrange the trap while simultaneously checking the remote areas.

  Furthermore, the shape of the visible region may be a three-dimensional shape including the height direction. For example, in the case of the rectangular parallelepipeds 802 and 892 having a height H as shown in FIG. 8D, the invisible process is performed on the objects arranged in the portion higher than the height H. For an object placed across both the region higher than the height H and the region lower than the height H, the visualization processing is performed on the portion placed in the lower region, and the portion placed in the region higher than the height H is performed. Can be made invisible. For example, it can be realized by forming one object by a plurality of partial objects and performing these processes for each partial object. As described above, when a three-dimensional area is used as the visible area, when there is a tall object 890 in the front area within the visible area, the tall object 891 behind the high object 890 can be confirmed while the tall object 890 is displayed. It becomes possible. For an object that straddles the height H, it is preferable to perform an activation process for the player operation.

[Second Embodiment]
The present embodiment is a plurality of virtual spaces in which the game space is discontinuous, and is different from the first embodiment in that a plurality of visible region operation images are displayed for these virtual spaces. The other points are the same as in the first embodiment. Hereinafter, a description will be given focusing on differences from the first embodiment.

  In the present embodiment, the virtual space that is the game space includes five discontinuous virtual spaces a to o. In the example of FIG. 9, visible region operation images 901 </ b> A to 901 </ b> C for three virtual spaces of the five virtual spaces are displayed on the display unit 302 together with the object operation image 951. That is, the visible region operation images 901A to 901C correspond to any one of the three virtual three-dimensional spaces, and are quarter views of the entire region of the corresponding virtual space. The virtual space displayed as the visible region operation image 901 can be changed by the player operating the arrows 910 and 911 displayed at the upper and lower portions of the visible region operation images 901A to 901C.

  Based on FIG. 10, the process of this embodiment is demonstrated. In step 1001, three visible region operation images 901A-C are generated. Here, as an initial state, the visible area operation images 901A to 901C correspond to the virtual spaces i to d, respectively, and the virtual space c corresponding to the visible area operation image 901B is selected as a space to be displayed on the object operation image. It is assumed that The visible region determining means determines the visible region by the same processing as in the first embodiment (step 1001), generates a visible region operation image for each virtual space (i) to (d) (step 1003), and operates the visible region operation. An object operation image 951 for the virtual space C corresponding to the image 901B is generated (step 1005), and the three visible region operation images 901A to 901C and one object operation image 951 are displayed on the display unit 304 (step 1007). . Here, the three visible area operation images 901 </ b> A to 901 </ b> C are arranged on the display unit 302 with an interval of h <b> 2 and h <b> 3 larger than the height h <b> 1 of the visible area display 902. Even when the visible region display 902 is moved to the upper end or the lower end of the visible region operation image 901B, it is possible to prevent the visible region operation image 901A or 901C from overlapping. Similarly, when the visible region operation images are arranged on the left and right sides, it is also preferable that the visible region display is arranged so as not to overlap with the adjacent visible region operation images.

  The visible region moving process (step 1011 to step 1019) and the object moving process (steps 1021 to 1029) are related to the selected virtual space c by the same process as the process in step 611 to step 635 in the first embodiment. ) And object operation image movement processing (steps 1031 to 1035) are executed.

  In the present embodiment, a process for changing the selection of the visible region operation image is executed in order to change the virtual space to be displayed on the object operation image (steps 1037 and 1039). That is, when the player touches one of the visible region visible region operation images 901 </ b> A or C displayed on the touch panel 110, the touch detection unit 301 detects this and outputs it to the player input processing unit 305. Based on this, the player input means 305 determines whether or not the touch by the player is a selection with respect to either the visible region / visible region operation image 901A or C (step 1037). If the selection is made for either the visible region visible region manipulation image 901A or C, a predetermined area for the virtual space corresponding to the selected visible region visible region manipulation image is determined as the visible region, and the visible region A visible region display is displayed on the operation image (step 1039), and an object operation image for a part of the virtual space is generated and displayed (step 1041).

  Next, a process of changing the virtual space displayed in the visible region operation images 901A to 901C is executed (step 1041). For example, when the player input processing means 305 determines that the player has touched the arrow 910 and changed the virtual space (step 1043), the virtual spaces displayed in the visible region operation images 901A to 901A to 901C These visible region operation images are generated and displayed (step 1045).
