  Hereinafter, various embodiments of the present invention will be described with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, and extends to the invention described in the claims and equivalents thereof.

(Outline of game device)
FIG. 1 is a schematic diagram for explaining an example of a game provided by the game device.

  The game device is, for example, a portable terminal such as a multifunctional mobile phone (so-called “smartphone”) owned by the player. The game device may be a server that can communicate with a mobile terminal owned by a player.

  The game device executes a game according to a specific game program, and displays a game image indicating the progress of the game being executed on the screen. The game image indicates a virtual game space including at least one type or a plurality of types of objects. The virtual game space is defined by two coordinate axes, and objects having two-dimensional coordinates are arranged in the two-dimensional virtual game space. The virtual game space may be defined by three coordinate axes. In this case, an object having three-dimensional coordinates is arranged in the three-dimensional virtual game space. Hereinafter, a case where the game image is an image showing a two-dimensional virtual game space will be described as an example.

  The shape of the object is a shape of various closed figures such as a circle, a square, a rectangle, a diamond, or a bar. The shape of the object may be a shape imitating a predetermined object (such as a car, tree, person, animal, plant, building, or fossil). The shape of the object may be deformed as time passes.

  In the example shown in (1) of FIG. 1, the game apparatus displays nine objects A on the screen. Each of the nine objects A is associated with a parameter value a (for example, “5”). The parameter value a relates to display control of the corresponding object A.

  The game device displays an object B different from the object A on the screen. A parameter value b (for example, “3”) is associated with the object B. The parameter value b relates to display control of each object A. The game device controls display of the object B so that the object B appears in the screen, the object B is hidden from the screen, and / or the object B moves in the screen in response to an operation by the player.

  As shown in (1) of FIG. 1, the game apparatus controls the display of the object B so that the object B moves in the two-dimensional virtual space in accordance with the drag and drop operation of the player. A case where the game apparatus has a pointing device such as a touch panel and the object B is displayed on the screen of the game apparatus will be described as an example. If the object B is displayed at the position on the screen designated by the player, the game device may cause the object B to move in the two-dimensional virtual space in accordance with the movement of the designated position on the screen by the player. B is displayed and controlled. Then, when the game device determines that the designation of the position on the screen by the player has been completed, the game apparatus displays the object B at the designated position corresponding to the last position on the screen designated by the player (the object B is the designated position). The display is controlled to stop.)

  The operation by the player may be a position specifying operation such as a tap operation or a double tap operation by the player. For example, the game device displays the object B on the screen so that the designated position input by the player's position designation operation matches the center position of the object B.

  In the example shown in (2) of FIG. 1, the object B displayed at the designated position is displayed so as to overlap the object A based on the designated position input by the player. For example, when at least a part of the object A and at least a part of the object B overlap, the game apparatus hides the overlapping part of the object A with the object B. As a result, the object B is displayed so as to overlap the object A.

  The game device determines, for each object A, whether there is a portion where the display area of each object A and the display area of object B overlap. Hereinafter, a portion where the display areas of the objects overlap may be referred to as an overlapping portion of the objects.

  The game device calculates the overlapping area of the overlapping portion with the object B for the object A having the overlapping portion with the object B. Then, for each object A, the game apparatus calculates an overlapping ratio (a value obtained by dividing “the overlapping area of the overlapping portion with the object B” by “the area of the object A”).

  As shown in FIG. 3 (3), the entire middle A (second from the top and second from the left) object A (hereinafter sometimes referred to as “object A 1”) overlaps part of the object B. The overlapping ratio of the object A1 is 100%.

  A part of the first object A from the top and the second from the left (hereinafter sometimes referred to as “object A2”) overlaps a part of the object B. The overlapping area where the object A2 and the object B overlap is 15% of the area of the object A2. Similarly, the overlapping area of the portion where the second object from the top and the first object A from the left (hereinafter sometimes referred to as “object A3”) and the object B overlap is 15% of the area of the object A3. The overlapping area of the portion where the second object from the top and the third object A from the left (hereinafter sometimes referred to as “object A4”) and the object B overlap is 15% of the area of the object A4. The overlapping area of the portion where the third object A and the second object A from the left (hereinafter sometimes referred to as “object A5”) and the object B overlap is 15% of the area of the object A5.

  The first object A from the top and the first object A from the left (hereinafter may be referred to as “object A6”), and the first and third object A from the top and from the left (hereinafter referred to as “object A7”). ), The third object A from the top and the first object A from the left (hereinafter may be referred to as “object A8”), and the third from the top and the third object A from the left (hereinafter referred to as “object A9”). Are not overlapped with the object B, respectively. For this reason, the overlapping ratio of each of the objects A6 to A9 is 0%.

  For each object A, the game device sets a value calculated by multiplying the parameter value b of the object B by the overlapping ratio of each object A as a change value of each object A. Since the parameter value b of the object B is “3”, the change value of each object A is as shown in (4) of FIG.

  When the game device calculates the change value of each object A, the value calculated by subtracting the change value of each object A from the current parameter value a of each object A is set as a new parameter value a. The new parameter value a of each object A is as shown in (5) of FIG.

  The game device displays each object A according to the display mode corresponding to the new parameter value a after calculation. In the example shown in (5) of FIG. 1, the game device changes the size of each of the objects A2 to A5 to a size corresponding to the new parameter value a “4.55”. For example, since the parameter value a of each of the objects A2 to A5 has been changed from “5” to “4.55”, the game device changes the size of each of the objects A2 to A5 to the size shown in (1) of FIG. Change to a smaller size.

  Similarly, the game device changes the size of the object A1 to a size corresponding to the new parameter value a “2”. For example, since the parameter value a of the object A1 is smaller than the parameter values a of the objects A2 to A5, the game device changes the size of the object A1 to be smaller than the sizes of the objects A2 to A5. . Further, since the parameter values a of the objects A6 to A9 are not changed, the sizes of the objects A6 to A9 are not changed.

  The display mode of the object A according to the parameter value a may be a display mode of the object A according to the transmittance according to the parameter value a. In this case, when there is another object C (not shown) at a position overlapping the lower layer of the object A, the object A is transparently displayed with the transmittance according to the parameter value a, so that the object C overlapping the lower layer of the object A is displayed. Can be visually recognized. In this case, the transmittance of the object A may increase as the parameter value a of the object A decreases. Further, when the parameter value a of the object A becomes a predetermined value (for example, “0”) or less, the transmittance of the object A becomes 100%, that is, even if the display control of the object A is performed so that the object A is not displayed. Good. Further, when the transmittance of the object A reaches 100%, the object A may be deleted from the screen.

  When the parameter value a is larger than a predetermined value (for example, “0”), the display mode of the object A according to the parameter value a is not changed, and the parameter value a is equal to or smaller than the predetermined value. Alternatively, a display mode in which the object A is not displayed may be used. For example, when the parameter value a is equal to or less than a predetermined value, the display of the object A may be controlled so that the object A is not displayed, or the object A may be deleted from the screen. The display mode of the object A corresponding to the parameter value a may be a display mode in which a number indicating the parameter value a is displayed in the display area of the object A.

  As described above with reference to FIG. 1, in the game device of the present embodiment, the player simply displays the object B at the specified position, and the display mode of each of the plurality of objects A is changed to the parameter value of each object A. It can be changed individually according to a. Therefore, the game device according to the present embodiment can provide a user interface for realizing various game developments without complicated operations by the player. Further, the game apparatus can display the object B at an arbitrary position by a position specifying operation by the player. Therefore, the player can perform a fine operation such as displaying (arranging) the object B in accordance with the shape of the object A in order to efficiently change the parameter value a of the object A. Thus, the game device can provide an intuitive user interface for the player.

  In this case, when the entire area of the cover object 400 displayed and movable on the game screen 500 is smaller than the area of the game screen 500, the movable cover object 400 may not be hidden. For example, the cover parameter value of the movable cover object 400 may not be updated, and the movable cover object 400 may not have the cover parameter value. As a result, the movable cover object 400 becomes an enemy character for the player, and the difficulty of displaying the item object can be improved, and various game developments can be realized. In this case, the progress processing unit 251 no longer has the cover object 400 that overlaps with the item object 401 among the cover objects 400 of the cover layer other than the cover layer including the cover object 400 that automatically moves. If it is, it is determined that the game in progress has ended.

(Modification 5)
When a plurality of cover layers 410 are associated with a game stage, the cover object 400 included in at least one of the plurality of cover layers 410 is a game specific to the cover object 400 of the lower cover layer. It may be an effect. Thereby, the difficulty level which displays an item object can be improved, and it becomes possible to implement | achieve various game development.

  For example, a predetermined transmittance (for example, 50%) is set in the cover object 400 (hereinafter, also referred to as “specific cover object”) that provides a specific game effect, and the player can select the specific cover object. The cover object 400 of the cover layer one layer below can be visually recognized.

  The cover parameter value of the specific cover object is not updated or has no cover parameter value. When the tool object 403 is displayed at the specified position in the position specifying instruction, the specific cover object is the tool object. Even if there is an overlap with 403, the display of the specific cover object is maintained.

  In this case, the progress processing unit 251 determines whether or not there is a cover object 400 having an overlapping portion with the tool object 403 among the lower layer cover objects 400 arranged in the cover layer 410b one layer below the specific cover object. To do. When the tool object 403 overlaps with the lower layer cover object 400, the progress processing unit 251 performs the same process as steps S208 to S210 of the game progress process, and updates the cover parameter value of the lower layer cover object 400. At this time, if the tool object 403 overlaps with both the specific cover object and the lower layer cover object 400 in step S209, the progress processing unit 251 sets the tool parameter value of the tool object 403 to the overlap ratio calculated in step S208. Is multiplied by a predetermined coefficient (a number smaller than 1 and larger than 0) to calculate a change value.

  When the cover parameter value of the lower layer cover object 400 that overlaps with the specific cover object becomes equal to or less than the predetermined value “0”, the display processing unit 252 hides the lower layer cover object 400 and also hides the specific cover object. And Immediately before the specific cover object is hidden, the display processing unit 252 displays an effect moving image in which the specific cover object is sucked in a place where the hidden lower layer cover object 400 is displayed. May be. By displaying such an effect moving image, for example, the game system 1 provides the player with an effect that a specific cover object imitating the water surface is sucked into a hole vacated when the cover object 400 is hidden. It becomes possible to do.

  When the cover parameter value of the predetermined cover object 400 is equal to or less than the predetermined value “0”, the progress processing unit 251 creates a new cover on one layer of the cover layer 410 where the cover object 400 is arranged. The layer 410 may be generated, and the specific cover object may be arranged on the new cover layer 410. Note that, immediately before the specific cover object is hidden, the display processing unit 252 may display an effect moving image in which the specific cover object springs up from a place where the predetermined cover object 400 is displayed. Good. By displaying such an effect moving image, for example, the game system 1 provides the player with an effect that a specific cover object that imitates water from a hole that is vacated when the cover object 400 is hidden.
