Description

  The present invention relates to a computer program and a computer-implemented method, and more particularly to a computer program and a computer-implemented method that facilitate user operations on various objects arranged on a virtual space plane.

  Some conventional computer programs, particularly game programs, arrange a plurality of objects on a three-dimensional virtual space plane, generate a view image projected from a virtual camera and output it to the screen as the game progresses. Many. As an example, FIG. 1 is a screen example of a conventional game program in which various objects are arranged on a land (virtual space plane) where there are no buildings in a virtual space by user operation to create a city. is there. In such a game, the user can place objects such as roads and buildings on the land on the plane according to his / her preference. Furthermore, the user can perform predetermined user operations including movement and change through selection of objects arranged on the virtual space plane in accordance with the rules of the game.

  In the game as described above, the user can select an object by touching a specific area on the touch display corresponding to the position where the object is placed on the game image displayed on the touch display. Thus, it is common to advance the game interactively. For example, on the touch display, the user touches a part where a specific object (for example, building object a) displayed as shown in FIG. 1A is displayed with a finger or a stylus pen. The object can be selected and operated.

  However, in such games, the position of the virtual camera arranged in the virtual space can often be controlled only by movement accompanying zoom-in or zoom-out and horizontal movement in a predetermined direction along the horizontal plane. In this case, for example, when the user selects another object (for example, a building object b adjacent to the building object a) arranged adjacently behind the object, the user selects the object adjacent to the front (building object a). ) Must be touched to avoid the part where it is displayed. This is because the front building object is displayed in the overlapping area of the front and rear building objects, and the rear building object is hidden. In some cases, the rear building object may be completely hidden behind the front building object, making it impossible to select by touch on the touch display.

  Thus, when the user wants to select the building object b by touch, conventionally, as shown in FIG. 1B, the building object a is once moved to another place by a user operation, and the entire building object b is displayed. After making it possible, the user has to make another selection by touching the building object b.

  On the other hand, as a device in the game program in the prior art for such a situation, it is determined whether each building object has a certain size (especially height) or whether a plurality of objects overlap. In such a case, there is a case where a transparent building process is performed on a front building object (building object a) having a certain size or more so as to be “not selectable by the user”. However, in this case, it is necessary to provide various parameters for each building object, and there is a problem that processing is complicated and processing cost increases.

  Therefore, it would be advantageous to provide an improved game program that allows efficient control over objects to facilitate user operations such as touch operations.

  An object of the present invention is to provide a computer program for efficiently performing user operation control and visual display control on an object in order to facilitate user operation on various objects arranged on a virtual space plane, Accordingly, it is an object of the present invention to provide a computer program that can easily and smoothly realize a user operation (such as object selection by a touch gesture operation) on various objects without giving the user troublesome operations.

  In order to solve the above-described problems, a computer program and a computer-implemented method for performing operation control and display control on an object arranged on a virtual space plane are provided.

  A computer program according to the present invention includes: a first determination unit that determines a position of a virtual camera in a virtual space in accordance with a user input and determines a visual field area of the virtual space; a deactivation screen in a display area of a user screen A second determination unit that determines a deactivation plane area of a view field area that is associated with the area, and performs a transparency process and a deactivation process on an object that is at least partially arranged on the deactivation plane area The computer is caused to function as a processing unit that performs the processing and a generation unit that generates a game image based on the field of view using the image of the object that has been subjected to the transparent processing for output to the user screen.

  In the computer program of the present invention, the inactive screen area is defined based on a reference point on the center line of the display area of the user screen. Furthermore, in the computer program of the present invention, the space plane in the virtual space is formed in a lattice shape, and in the second determination unit, the association is performed with one lattice on the space plane with respect to the reference point of the display area. It is performed by specifying as a reference grid.

  In addition, the computer-implemented method of the present invention includes a step of determining the position of the virtual camera in the virtual space and determining a view area in the virtual space in response to a user input, a deactivation screen in the display area of the user screen Determining a non-activated planar area in a viewing area to be associated with an area, wherein the non-activated screen area is defined based on a reference point on a center line of the display area, The plane is formed in a grid shape, and the above association is performed by specifying one grid on the spatial plane as the reference grid with respect to the reference point, at least a part is disposed on the non-activated plane region A step of performing transparency processing and deactivation processing on the image of the object, and a field of view area using the image of the object subjected to the transparency processing for output to the user screen Comprising the step of generating a game image based.

First, a basic configuration of a system (here, a game system) for executing a computer program according to an embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic block diagram showing only main components of the game system.

  As shown in FIG. 2, the game system 100 includes user terminals 10-1 to 10-4 (hereinafter collectively referred to as “user terminals 10”) and a game server 50, and a network 30 is provided between these elements. To communicate via. The user terminal 10 may be any device that can display a game image generated by the game server 50 and / or the user terminal 10 using an application such as a browser. For example, a smartphone, a tablet terminal, a game console, a notebook PC, a desktop Although PC etc. are included, it is not limited to these.

  As illustrated, the user terminal 10 includes a terminal display unit 11, a terminal input unit 12, a terminal processing unit 13, a terminal communication unit 14, a terminal storage unit 15, and the like, which are electrically connected to each other via a bus. Is done. The terminal display unit 11 displays a game image received from the game server 50 by the terminal communication unit 14 and temporarily stored in the terminal storage unit 15 through a browser. The terminal display unit 11 can be realized by, for example, a liquid crystal display (LCD) or the like. In the embodiment, the terminal display unit 11 is particularly preferably configured as a multi-touch screen. The terminal input unit 12 includes commands for controlling the operation of a virtual camera arranged in the three-dimensional virtual space, and user actions for various objects arranged in the three-dimensional virtual space (“construction”, “selection”, “object”). Enter a command to make a move. As an input means, it can be a character input by a keyboard or a virtual keyboard, a click of an object by a mouse, a touch input by a finger at a position on the touch screen corresponding to the object position or an input by a stylus, and a combination thereof. It is not limited to these.

  Based on the input command received by the terminal input unit 12, the terminal processing unit 13 creates a user command and communicates with the game server 50 through the terminal communication unit 14 and the network 30. The terminal storage unit 15 stores various data associated with the user terminal and applications such as a browser necessary for displaying image data, and also temporarily stores various data such as image data received from the game server 50. . The terminal processing unit 13 may also be configured to execute the game program module stored in the terminal storage unit 15 on the terminal side based on various data received by download from the game server 50.

  On the other hand, the game server 50 includes a processing unit 51, a main memory 52, an external memory 53, a user interface 54, a communication unit 55, a disk drive 56, and the like, which are electrically connected to each other via a bus. The The processing unit 51 controls the progress of the game by loading the program module stored in the external memory 53 and various data stored in the disk drive 56 into the main memory 52 and sequentially executing the program. . In particular, the processing unit 51 is configured to generate a display game image on the user terminal 10 and return it to the user terminal 10 via the communication unit 55. The user interface 54 is accessed by the administrator of the game server 50 and performs various server function settings and network settings.

  In addition, you may comprise so that the user terminal 10 may bear all or one part of various functions as an information processing apparatus regarding the said game server 50. FIG. In this case, the information processing apparatus is configured by the user terminal 10 alone, or the information processing apparatus is configured by the user terminal 10 and the game server 50 as a whole.

  Next, with reference to FIG. 3 and subsequent figures, specific information processing related to a game program that performs control (particularly activation control and display control) on an object according to an embodiment of the present invention will be described.

  FIG. 3 is a schematic diagram showing main functions implemented by a computer program that performs activation control and display control on an object according to an embodiment of the present invention. In particular, FIG. 3 is an exemplary functional block diagram relating to various program modules (functional blocks) mainly stored in the terminal storage unit 15 in the user terminal 10. FIG. 3 shows a functional block diagram for implementing each function on the user terminal 10 side and executing information processing using various data downloaded from the server 50. Each function is implemented on the server 50 side. It should be understood by those skilled in the art that this may be done.

  As the input / output device of the user terminal 10, here, the touch screens 11 and 12, particularly a multi-touch screen that enables a user to touch with a plurality of fingers are assumed. The input unit 10a receives a command by a user input by a touch gesture operation through a touch screen. Touch gesture operations for user commands include, but are not limited to, operations such as tapping, long pressing, pinching, stretching, sliding, swiping, and rotating on the touch screen.

  The view area determination unit 10b determines the view area of the virtual space by manipulating and determining the position of the virtual camera in the virtual space in response to a user input, that is, a touch gesture operation. In this embodiment, although not limited to this, the virtual camera can only move in the height direction accompanying zoom-in / zoom-out and horizontally move in a predetermined direction along the horizontal plane, and can move in the virtual space. It is not assumed to move freely. Next, the visual field area determination unit 10 b temporarily stores spatial data including information on each object arranged on a plane in the visual field area in the visual field area in the storage unit 15 in the user terminal 10.

  In the display mode designating unit 10c, the display mode of the visual field area displayed on the screen is designated by a user command. For example, the “normal mode” is a mode for displaying a normal game image of the view area in the virtual space, and the “view mode” is an object for an object placed on the plane of the view area. This is a mode for enabling an object operation such as moving an object and previewing the operation result.

  When the screen display mode is set to “view mode” by the user input in the display mode designating unit 10c, the virtual space plane area determining unit 10d firstly compares the display area of the user screen with the view area in the virtual space. The spatial plane area of Then, a predetermined deactivation screen area for deactivating the user operation is specified from the display area of the user screen. Next, regarding the specified deactivation screen area, a plane area (deactivation plane area) in the visual field area in the virtual space is determined in association with each other. The non-activation plane area is an area where a transparency process and / or a deactivation process of a user operation is performed on the plane area and an image of an object arranged on the plane area.

In the transparency processing and deactivation processing unit 10e, first, an object arranged on the deactivation plane region determined by the virtual space plane region determination unit 10d is specified. The identified object is determined as a target object for the transparent process and the deactivation process. At least a part of the object is arranged on the plane area, that is, an object arranged across the boundary of the non-activated plane area may be determined as the target object. Next, a transparency process based on a predetermined transparency and a deactivation process for deactivating a user operation are performed on the target object.
As the transmission processing based on the predetermined transmittance, for example, a transmission processing by an alpha blend that is commonly used by those skilled in the art can be adopted. In this case, the transmittance is determined by appropriately selecting an alpha value. . Further, in the deactivation process for deactivating the user operation, the activation flag of the target object, which will be described later with reference to FIG. 4, is set to “inactivation”. When the activation flag is set to “inactive”, the touch (click) determination is set to off and no touch event is generated. That is, even when the user performs a touch gesture operation on the target object, the touch screen does not react at all.

  In the transmission processing and deactivation processing unit 10e, the transmission processing is also performed on a planar image (for example, an image of the ground) of the non-activation plane area of the visual field area associated with the deactivation screen area. You may comprise.

  In the image generation unit 10f, based on the spatial data temporarily stored in the terminal storage unit 15 by the visual field region determination unit 10b, the image and the plane region of the object subjected to the transmission processing and the deactivation processing unit 10e A game image based on the spatial data of the visual field region is generated using the planar image. Furthermore, in the game image, the boundary line of the inactivated screen area in the display area (or the boundary line of the plane area of the visual field area associated with the inactivated screen area) is superimposed so as to be clearly indicated. Also good.

  The object operation unit 10g uses a game image generated by the image generation unit 10f, and uses a game image generated by the image generation unit 10f on a virtual space plane. Let the user perform user operations. Finally, in the output unit 10f, the game image is output to the user screen (touch screen).

  Various data used in each functional block shown in FIG. 3 may be temporarily stored in the terminal storage unit 15 in a table format. For example, FIG. 4 is an exemplary object table that contains object data. As shown in the figure, the object table is not limited to this, but for each object arranged on the virtual space plane, the object ID, the icon type, the shape (L, W, H), the arrangement position on the virtual space plane. (X, y), object data including an activation flag is accommodated.

  The object ID is an identifier that uniquely identifies the object. The icon type indicates the type of icon of the object placed on the virtual space plane. For example, AABB indicates a “bank” object, YYYY indicates a “convenience store” object, and so on. The shape is depth (W), width (W), and height (H) data of the object in the three-dimensional virtual space. The arrangement position on the virtual space plane is position data in the (x, y) coordinate system. As will be described later, the virtual space plane may be formed in a lattice shape, and each object may be arranged on the lattice. In this case, it is understood by those skilled in the art that the data is a lattice number. . The activation flag is a flag for setting whether or not the user can perform a touch gesture operation such as touch selection on the touch display by the user. For example, “1” indicates “activation” and “0” indicates “activation”. Data indicating "inactivation". It is set to “1” in the initial state, and is set to “0” when it is determined as an object to be deactivated in the transparent process and deactivation processing unit 10e. It should be noted that the above-described various program modules and various data and tables are merely used for illustration, and it will be understood by those skilled in the art that the present invention is not limited thereto.

  Next, with reference to FIG. 5 to FIG. 7, an example relating to a basic aspect of object transparency processing executed using the game program according to the embodiment of the present invention will be described. FIG. 5 shows a spatial image of the space plane (xy plane) region 60 in the field of view from the virtual camera 1 and the building objects 80, 85, 90 arranged on the space plane region 60. Specifically, the virtual space plane is formed on a lattice, and the space plane region 60 is formed of lattices [x1, y1] to [x7, y7]. Building on 8 grids [x2, y2] to [x5, y3], 2 grids [x4, y4] to [x5, y4], and 4 grids [x6, y5] to [x7, y6] Objects 80, 85, and 90 are arranged, respectively.

  In particular, a part of the building object 85 is hidden behind the large building object 80 in the spatial image. For this reason, when the user tries to select the building object 85 with a touch gesture, it is difficult to select the building object 85 so as to avoid the building object 80, and there is a possibility that the building object 80 will be selected by mistake. is there.

  When the display mode is set to “normal mode”, a game image based on the spatial image of FIG. 5 is generated and displayed on the screen, whereas when set to “view mode”, FIG. Alternatively, a game image based on the spatial image of FIG. 7 is generated and displayed on the screen. In FIG. 6 and FIG. 7, the space plane region 60 is formed by a non-activation plane region 61 ′ and an activation plane region 62, and an L-shaped plane boundary line L <b> 1 therebetween. In the inactivation target area 61 ′, the planar image is made translucent by performing a transmission process based on a predetermined transmittance (for example, 50%).

  In addition, in FIGS. 6 and 7, the building objects 85 and 90 on the activation target area 62 are displayed on the screen as they are in the spatial image (without performing any visual processing). A visual display control process is performed on the image of the building object 80 on the activation plane area 61. Specifically, in FIG. 6, the object image is translucent (building object 80 ′) by performing a transmission process based on a predetermined transmittance (for example, 50%), and in FIG. 7, the transmittance is 100%. To make the building object 80 transparent (hidden). As a result, the entire building object 85 arranged behind the building object 80 is displayed. Note that the transmittance in the transmission process may be a fixed value, or may be set dynamically based on the distance from the boundary line, and may be an arbitrary value.

  Further, the user operation on the building object 80 is deactivated (that is, the activation flag is set to “0”) so that the user cannot select the building object 80 even if the user touches the building object 80 image portion. . Thereby, selection of the building object 85 can be made easy.

  As described above, by implementing the computer program according to the embodiment of the present invention, it is possible to facilitate the user operation on various objects arranged on the virtual space plane. More specifically, by implementing a computer program that efficiently performs user operation control and visual display control on objects, user operations on various objects can be performed without giving users troublesome operations. (Object selection by touch gesture operation etc.) can be realized easily and smoothly.

  Next, with reference to FIG. 8, an example of the association between the deactivated plane area in the visual field area in the virtual space and the deactivated screen area defined in the display area of the user screen will be described. As shown in FIG. 8, in the screen display area 11 (square frame) of the user screen, a screen reference point P1 is defined below the center on the center line L3 indicated by a broken line. An L-shaped screen boundary line L2 extends from the screen reference point P1, and the upper part is formed as an inactivated screen area A1 and the lower part is formed as an activated screen area A2. Note that the angle of the screen boundary line L2 is adjusted in advance so that the screen boundary line L2 can extend along the periphery of the lattice indicated by the dotted line inside the screen display region 11. It should be understood by those skilled in the art that the screen reference point P1 is not limited to a point on the center line L3.

  When the screen display mode is set to “view mode”, first, the screen display area 11 in the spatial plane area 60 of the visual field area of the three-dimensional virtual space that is associated with the screen display area 11. The reference grid C1 of the activation plane region corresponding to the position of the screen reference point P1 is specified. Then, according to a predetermined rule, a plane boundary line L1 corresponding to the screen boundary line L2 can be configured by extending two straight lines along a lattice from a specific point of the reference lattice C1. it can. By determining the plane boundary line L1 in this way, the non-activation plane area 61 ′ and the activation plane area 62 as shown in FIGS. 6 and 7 are determined in the space plane of the visual field area of the virtual space. Can do. Note that the plane boundary line L1 and the screen boundary line L2 are not limited to the L shape, and may be composed of three or more straight lines such as a staircase shape according to a predetermined rule. It can be made into arbitrary shapes according to a shape.

  FIG. 9 is a flowchart illustrating an example of a series of information processing in a computer-implemented method for performing activation control and display control on an object according to an embodiment of the present invention. This flowchart is started when the screen display mode is set to “view mode”.

  In step S10, the position of the virtual camera in the virtual space is determined according to the user input. In step S20, the visual field area of the virtual space is determined based on the determined position of the virtual camera as shown in FIG. Next, in step S30, as shown in FIG. 8, a predetermined deactivation screen area for deactivating the user operation is specified from the display area 11 of the user screen. Furthermore, in step S40, the space plane area 60 in the visual field area in the virtual space is associated with the display area of the user screen.

  Subsequently, in step S50, as shown in FIG. 8, it corresponds to the position of the screen reference point P1 of the screen display area 11 in the spatial plane area 60 of the visual field area associated with the screen display area 11. The reference grid C1 of the activation plane region is specified. Next, the non-activated planar region 61 shown in FIGS. 6 and 7 is determined based on the planar boundary line L1 formed from the reference lattice C1 according to a predetermined rule.

  Subsequently, in step S70, an object at least a part of which is arranged on the non-activation plane area 61 determined in step S60 is specified, and in step 80, a predetermined object image is determined for the specified object image. And a deactivation process for setting the activation flag to “inactive” (object 80 ′ in FIG. 6). In addition, in step S90, a transmission process based on a predetermined transmittance is also performed on the planar image of the non-activated plane region 61 determined in step S60 (the non-activated plane shown in FIGS. 6 and 7). Region 61 ').

  In step 100, a game image is generated based on the spatial data of the visual field area. Here, the image of the object that has been subjected to the transmission process in step S80 and step S90 and the planar image of the inactivated planar region 61 'are used. Further, in step S110, the boundary line of the inactivated screen area A1 in the display area (or the boundary line of the inactivated plane area) is fixedly and explicitly superimposed on the game image.

  The game image configured in this way is output to the user screen in step S120 (an example of a game image will be described later with reference to FIG. 10). A series of steps from step S10 to step S120 is repeated continuously while the user input continues, for example, while the user operates the screen with a touch gesture that scrolls the slide. It should be understood by those skilled in the art that each of the steps described above with reference to FIG. 9 is merely an example, and the present invention is not limited to all these implementations and implementation order.

  Finally, referring to FIG. 10, an example of a game screen output through step S120 of FIG. 9 will be described. FIG. 10A is an example of a game screen for the visual field area of the virtual space when the screen display mode is set to “normal mode”. All objects such as power plant objects and hotel objects arranged on the space plane are displayed as usual. FIG. 10B is an example of a screen when the screen display mode is changed from the state of FIG. 10A to “view mode”. On the screen, an inactive plane area corresponding to the lower area A1 is transparently displayed from the screen boundary line L2, and an object such as a hotel object arranged on the inactive plane area is transparently displayed. I understand. The user operation is deactivated for the transparently displayed object, and the user command by the touch gesture is invalid.

  FIGS. 10C and 10D are screen examples when the user continues to scroll up and down by sliding the screen from the “view mode” in FIG. 10B. The virtual camera can be horizontally moved in a predetermined direction in the virtual space by the vertical scrolling operation. FIG. 10C is a screen example when the virtual turtle is horizontally moved upward in the screen by the scroll roll operation in the downward direction while the screen boundary line L2 is fixed from FIG. 10B. On the way, when at least a part of the power plant object crosses the screen boundary line L2, the power plant object is transparently displayed. FIG. 10D is a screen example when the virtual is horizontally moved downward by an upward scroll roll operation while the screen boundary L2 is fixed from FIG. 10C. When the location of the place object and the hotel object deviates from the non-activated plane area and enters the activated plane area, these objects are switched from the transparent display to the normal display.

  As described above, by implementing the computer program and the computer mounting method according to the embodiment of the present invention, it is possible to facilitate user operations on various objects arranged on the virtual space plane. More specifically, by implementing a computer program and a computer mounting method for efficiently performing user operation control and visual display control on an object, various objects can be obtained without giving the user troublesome operations. User operations (such as object selection by touch gesture operation) can be realized easily and smoothly.
