Description

[Technical field]

[0001] The present invention relates to an information processing device and a program for accepting a selection operation by a user. [Background technology]

[0002] Games that allow game objects to be synthesized are known (see Patent Document 1). For example, in a game in which a user obtains multiple types of items, an item synthesis process may involve having the user select multiple items that belong to the same group, and an information processing device may then execute a predetermined process on the selected items. In such a case, in order to have the user select an item to be processed, candidate items that belong to the same group are displayed, and a selection operation for each item is accepted from the user.

[0003] [Patent Document 1] JP 2018-114356 A Summary of the Invention [Problem to be solved by the invention]

[0004] If the user were to perform the above-described selection operation for each of the multiple items to be selected, the operation would be time-consuming if there were a large number of items to be processed. In particular, if items belonging to the same group are selected as selection candidates, the items in the selection candidates will be displayed similarly to each other, making it difficult for the user to perform the selection operation and increasing the risk of incorrect selection. On the other hand, if the information processing device were to automatically determine the items to be processed, there is a possibility that the items to be processed will not be the ones desired by the user.

[0005] The present invention has been made in consideration of the above-mentioned situation, and one of its objectives is to provide an information processing device and program that can efficiently make selections in line with the user's wishes when receiving selection operations from the user for multiple items. [Means for solving the problem]

[0006] An information processing device according to one embodiment of the present invention includes a candidate item display control means for causing a display means to display, among a plurality of items, a plurality of candidate items which belong to the same group as a designated item as candidates for selection by the user; a selection control means for changing one or more candidate items to a selected state in response to a user operation when the plurality of candidate items are displayed; and a processing execution means for executing a predetermined process based on the designated item and the candidate items in a selected state when a processing execution operation is received from the user when the one or more candidate items are in a selected state, wherein the selection control means is an information processing device characterized in that, when a bulk selection operation is received from the user, it changes one or more candidate items selected from the plurality of candidate items in accordance with given conditions to a selected state collectively.

[0007] A program according to one aspect of the present invention is a program for causing a computer to function as: a candidate item display control means for causing a display means to display, among a plurality of items, a plurality of candidate items belonging to the same group as a designated item as candidates for selection by a user; a selection control means for changing one or more candidate items to a selected state in response to a user operation when the plurality of candidate items are displayed; and a process execution means for executing a predetermined process based on the designated item and the selected candidate items when a process execution operation is received from the user when the one or more candidate items are selected, wherein the selection control means changes one or more candidate items selected from the plurality of candidate items according to a given condition to a selected state collectively when a collective selection operation is received from the user. This program may be provided by being stored in a computer-readable, non-transitory information storage medium. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0010] Fig. 1 is a configuration block diagram showing the overall configuration of an information processing system 1. As shown in Fig. 1, the information processing system 1 includes a client device 10 that functions as an information processing device according to an embodiment of the present invention, and a server device 20. The client device 10 is connected to the server device 20 via a communication network such as the Internet.

[0011] The client device 10 is an information processing device such as a smartphone, a tablet, or a personal computer, and includes a control unit 11, a storage unit 12, a communication unit 13, and an interface unit 14. The client device 10 is also connected to an operation input device 15 and a display device 16. In this embodiment, the client device 10 is used by a user who plays a game provided by the information processing system 1.

[0012] The control unit 11 includes at least one processor and executes various information processing according to programs stored in the storage unit 12. Specific examples of processing executed by the control unit 11 will be described later. The storage unit 12 includes at least one memory device such as a RAM, and stores the programs executed by the control unit 11 and data to be processed by the programs. The communication unit 13 is an interface for connecting to a communication network wirelessly or wired. The communication unit 13 communicatively connects the client device 10 to the server device 20.

[0013] The interface unit 14 is connected to the operation input device 15 and the display device 16 wirelessly or via a wire, and transmits and receives various data between these devices. Specifically, the interface unit 14 receives a control signal indicating the content of the operation input performed by the user to the operation input device 15 from the operation input device 15. In addition, the interface unit 14 transmits to the display device 16 a video signal indicating the content of the video to be presented to the user.

[0014] The operation input device 15 includes, for example, a touch sensor and an operation button, and receives an operation input from a user and transmits a control signal indicating the content of the operation input to the client device 10. The display device 16 is a liquid crystal panel or the like, and displays an image corresponding to a video signal received from the client device 10 on a display screen to present it to the user. Note that the operation input device 15 and the display device 16 may be configured integrally with the client device 10, for example by being arranged on the surface of a housing of the client device 10.

[0015] The server device 20 is an information processing device such as a server computer, and includes a control unit 21, a storage unit 22, and a communication unit 23. The server device 20 executes processes related to the games provided by the information processing system 1.

[0016] The control unit 21 includes at least one processor and executes various information processing according to programs stored in the storage unit 22. Specific examples of processing executed by the control unit 21 will be described later. The storage unit 22 includes at least one memory device such as a RAM, and stores the programs executed by the control unit 21 and data to be processed by the programs. The communication unit 23 is an interface for connecting to a communication network wirelessly or wired. The communication unit 23 communicatively connects the server device 20 to each client device 10.

[0017] Here, an overview of the game provided by the information processing system 1 will be described. In this game, the user of the client device 10 can obtain multiple types of items in the game. Furthermore, the user can "combine" the items he or she has obtained. This composition is performed on multiple items, and the parameter value set for one of the items (base item) is increased in exchange for the disappearance of other items (material items). The user can increase the parameter value of the base item and strengthen the item by performing composition using an unnecessary item among the items he or she owns as a material item. Note that composition does not necessarily mean that all material items are lost, and composition in this game may cause a change that increases the value of the base item instead of decreasing the value of the material item, such as decreasing the parameter value of the material item.

[0018] The items to be synthesized may be various items used in playing the game. Specifically, they may be the character that the user uses in playing the game, or items such as weapons that the character equips and uses. These items may be obtained as rewards by the user playing the game, or may be acquired by consuming in-game currency or the like. In addition, the user may be able to obtain items through a lottery held in the game, or through a paid purchase, etc.

[0019] Furthermore, in this game, users can synthesize items that belong to different groups as base items and material items, and can also synthesize items that belong to the same group. In the following, a synthesis in which a base item and a material item both belong to the same group is referred to as a "same-type synthesis," and a synthesis in which the base item and the material item belong to different groups is referred to as a "different-type synthesis."

[0020] In this game, when homogeneous synthesis is performed, a different result is obtained from that obtained by different synthesis. Specifically, when homogeneous synthesis is performed, it is possible to increase the value of a parameter that cannot be increased by different synthesis among the parameters of the base item. In the following, a parameter that cannot be increased by different synthesis but can be increased by homogeneous synthesis is called a focus parameter. It is assumed that a focus parameter is set for all items that can be the target of homogeneous synthesis. The user performs homogeneous synthesis mainly to increase the value of this focus parameter. By providing parameters that can be increased by homogeneous synthesis in this way, one of the goals of the game can be to collect multiple items of the same group that may normally become unnecessary, and it is possible to allow the user to play the game for a long time. In addition to the focus parameter, the value of other parameters set in the base item may be increased by homogeneous synthesis. In addition, there may be multiple types of focus parameters that can be increased by homogeneous synthesis. For example, the focus parameter may be a luck parameter, which has a higher value and provides an advantageous effect when an item with the set value is used during the game.

[0021] Here, the group of items that can be synthesized in the same type may be determined by various standards. As an example, items that belong to the same group may be only items of the same type (items that have the same name or appearance and are managed by the same identifier in the game). Alternatively, items that belong to the same lineage, such as an item and an item that can be obtained by changing that item in the game, may be considered to belong to the same group. For example, an item may be changed into another item (for example, of high rarity) by a process called evolution. In such a case, an item before evolution and an item after evolution may belong to the same group. Furthermore, even if items are obtained by different means, multiple items that have elements in common with each other, such as having a part of the name or a part of the parameter value in common, may belong to the same group. Regardless of the standard used, each item to be synthesized belongs to one of the groups, and if the items belong to the same group, they can be synthesized in the same type to increase the value of the parameter of interest, and if the items belong to different groups, they can be synthesized in different types but cannot be synthesized in the same type, and cannot be used to increase the value of the parameter of interest.

[0022] In this embodiment, the client device 10 provides an interface for accepting an operation of selecting a base item and a material item to be synthesized from a user when performing the above-described homogeneous synthesis. Hereinafter, the functions realized by the client device 10 in this embodiment will be described with reference to the functional block diagram of FIG. 2. The client device 10 is functionally configured to include a designated item specification unit 31, a candidate item display control unit 32, a selection control unit 33, and a process execution unit 34. These functions can be realized by the control unit 11 executing a program stored in the storage unit 12. This program may be provided to the client device 10 via a communication network such as the Internet, or may be provided to the client device 10 by storing it in a computer-readable information storage medium such as an optical disk.

[0023] The designated item identification unit 31 receives a designation operation from the user to designate one item from among the items possessed by the user. Hereinafter, the item designated by the user and received by the designated item identification unit 31 is referred to as a designated item Id. This designated item Id will ultimately be used as a base item in homogeneous synthesis.

[0024] Specifically, when the user performs an operation to instruct the start of like-kind synthesis, the designated item identification unit 31 acquires from the server device 20 a list of items possessed by the user. The acquired list of possessed items is then displayed on the display device 16 and presented to the user. The user designates one item that he or she wishes to use as a base item for the like-kind synthesis from among the presented items possessed by the user. The designated item identification unit 31 identifies this designated item as a designated item Id and notifies the candidate item display control unit 32 of this.

[0025] The candidate item display control unit 32 extracts items other than the designated item Id that belongs to the same group as the designated item Id identified by the designated item identification unit 31 from among the items possessed by the user, as candidates for selection by the user, and causes the items to be displayed on the display device 16. Hereinafter, the items that belong to the same group as the designated item Id and are displayed as candidates for selection by the user are referred to as candidate items Ic. In addition, the screen that the candidate item display control unit 32 causes the display device 16 to display and presents the candidate items Ic to the user is referred to as a selection receiving screen S.

[0026] In order to make it possible to extract candidate items Ic, each item possessed by the user may be associated with a group identifier for identifying the group to which the item belongs. The candidate item display control unit 32 extracts, as candidate items Ic, items associated with the same group identifier as the group identifier associated with the specified item Id.

[0027] FIG. 3 shows an example of a selection reception screen S. In this example, icon images representing a plurality of items belonging to the same group are displayed side by side. Among these items, an icon image displayed with the word "Target" in the upper left corner represents a specified item Id. The other icon images represent candidate items Ic. These candidate items Ic are arranged in order from the top to the bottom, and further from left to right in the same row. Furthermore, in the upper right corner of the area in which the candidate items Ic are arranged, a check box CB used to accept a collective selection operation described later is displayed with the words "Select all at once". In addition, a decision button B1 for confirming the selection by the user is displayed in the lower right, and a reset button B2 for canceling the selection is displayed in the lower left. Note that, if all the candidate items Ic cannot be displayed at once in the selection reception screen S, the candidate items Ic may be presented to the user by scrolling the candidate items Ic in response to a scroll operation by the user.

[0028] Here, the display order of the multiple candidate items Ic in the selection receiving screen S is determined according to a given criterion. Specifically, the multiple candidate items Ic are arranged in an order determined according to the value of the focus parameter set for each candidate item Ic (here, descending order of the parameter value). In addition, a number indicating the value of the set focus parameter is displayed superimposed on an icon image representing each candidate item Ic together with an icon image indicating the focus parameter (here, an image of a four-leaf clover). The value of the focus parameter is displayed because, as will be described later, the value of the focus parameter is the selection criterion when the user selects a candidate item.

[0029] The candidate item display control unit 32 may determine the overall display order of the candidate items Ic in consideration of other criteria, instead of determining the display order of the candidate items Ic only according to the value of the parameter of interest. For example, among the candidate items Ic, there may be an item that belongs to the same group as the designated item Id but cannot be selected as a material item for homogeneous synthesis at that time due to reasons such as game specifications. Specifically, an item that is set as a protected item so that the user does not mistakenly use it as a material item, or an item currently being used in the game (an item that is being used to play the game in the middle of playing the game, an item organized in a deck to be used immediately in playing the game, etc.) is restricted from being used as a material item. The candidate item display control unit 32 may display such items in a later order than other candidate items Ic. In the example of FIG. 3, the candidate item Ic that is protected among the eleven candidate items Ic is arranged at the last position, eleventh. In addition, such an unselectable item may be displayed in a different display mode from other selectable candidate items Ic, for example, grayed out, so that the user can recognize that it cannot be selected.

[0030] Also, the display order of the candidate items Ic that can be used as material items but are unlikely to be selected by the user as a material item may be placed after other candidate items Ic. Since material items are lost through synthesis, for example, items that cannot be obtained by general means or items with high rarity may not be actively selected by the user as a material item. Therefore, the display order of each type of item may be determined based on information such as a priority order predetermined for each type of item and a rarity order set for each item. The display order of the candidate items Ic may be determined by combining the multiple criteria described above. In the example of FIG. 3, a candidate item Ic with a lower priority order than the others is placed at the 10th position. However, since this candidate item Ic can also be selected as a material item, it is displayed before an item that cannot be selected (the 11th item).

[0031] As described above, in a state where the selection receiving screen S including a plurality of candidate items Ic is displayed, the selection control unit 33 changes one or more candidate items Ic to a selected state in response to a user operation. Specifically, when the user operates the operation input device 15 to select a candidate item Ic in the screen, the candidate item Ic is changed to a selected state. The operation of changing the candidate item Ic to a selected state may be, for example, an operation of tapping the touch panel at a position overlapping the position where the candidate item Ic to be selected is displayed. In addition, when the user performs an operation to select again a candidate item Ic that has already been selected, the selection control unit 33 changes the candidate item Ic from a selected state to an unselected state (i.e., the candidate item Ic has not yet been selected, the same as when the selection receiving screen S was initially displayed). In order to make it possible to distinguish between the candidate item Ic that has become a selected state and the candidate item Ic that has become an unselected state, the selection control unit 33 displays them in different display modes. Specifically, the selection control unit 33 adds a marker image indicating that a candidate item Ic that has been changed to a selected state is selected, or changes the display color of the candidate item Ic that is in a selected state.

[0032] In this way, the user can select any item that he or she wishes to use as a material item in homogeneous synthesis from among the multiple candidate items Ic presented in the selection reception screen S by executing an operation to change the desired candidate item Ic to a selected state, or to an unselected state as necessary. Note that the user can change multiple candidate items Ic to a selected state, but an upper limit may be set on the number of candidate items Ic that can be changed to a selected state at the same time. For example, if an upper limit is set on the number of material items that can be used in homogeneous synthesis, the selection control unit 33 will limit the number of candidate items Ic that do not exceed the upper limit and are selected at the same time.

[0033] Furthermore, when a collective selection operation is received from the user, the selection control unit 33 changes the state of a plurality of candidate items Ic to the selected state at once. Details of such collective selection control will be described later.

[0034] When the process execution unit 34 receives a process execution operation from the user after one or more candidate items Ic are in a selected state by a user operation on the selection receiving screen S, the process execution unit 34 executes a predetermined process based on the designated item Id and the selected candidate item Ic. In the example of FIG. 3, the process execution operation may be an operation on the decision button B1. Alternatively, after an operation on the decision button B1 is performed, the process execution unit 34 may display a confirmation screen including the designated item Id and the selected candidate item Ic, and when the user performs an operation on this confirmation screen to instruct the execution of a process, the process execution unit 34 executes the predetermined process.

[0035] As described above, the predetermined process in this embodiment is a process of synthesizing the same kind of item. That is, the process executing unit 34 performs a process of synthesizing the designated item Id as a base item and the candidate item Ic in the selected state as a material item into the base item. The process executing unit 34 may calculate the result of the synthesis process by itself and notify the server device 20 of the contents. Alternatively, the process executing unit 34 may transmit a request to execute the synthesis process to the server device 20 together with information on the identified base item and material item. In this case, the server device 20 calculates the result of the synthesis process and notifies the client device 10 of the result. In either case, the process executing unit 34 displays the result of the synthesis process on the display device 16 and presents it to the user.

[0036] In this homogeneous synthesis, as described above, the value of the focal parameter set for the base item changes, so the process execution unit 34 presents to the user at least the value of the focal parameter of the base item after synthesis as a result of the synthesis process.

[0037] The value of the focal parameter of the base item after compositing is determined according to the values ​​of the focal parameters set for the base item and the material items. More specifically, the new focal parameter value of the base item is the sum of the focal parameter values ​​of the base item and all selected material items. In other words, this homogeneous compositing causes the material item to disappear, but instead increases the focal parameter value of the base item by the focal parameter value of the material item.

[0038] It should be noted that an upper limit is set for the value of the focused parameter. This upper limit may vary depending on the type and rarity of the base item. When a synthesis process is performed, if the value of the focused parameter after synthesis calculated based on the original value of the focused parameter of the base item and the value of the focused parameter of the material item exceeds the upper limit, the value of the focused parameter of the base item is set to the upper limit.

[0039] Hereinafter, the control contents executed by the selection control unit 33 when the user performs a collective selection operation while the selection reception screen S is displayed will be described. Here, the collective selection operation is an operation of selecting the check box CB. When the user selects the check box CB, the selection control unit 33 selects one or more candidate items Ic from among the multiple candidate items Ic being presented according to a given condition, and changes the selected candidate items Ic to a selected state collectively. This can save the user the trouble of operating the candidate items Ic one by one to change them to a selected state. In the following, the collective selection operation performed by the selection control unit 33 to a selected state collectively when the user performs a collective selection operation is referred to as collective selection, and the candidate items Ic that are the subject of collective selection are referred to as collective selected items.

[0040] 4 shows an example of the selection receiving screen S in a state where a collective selection has been performed. In this figure, eight candidate items Ic are collectively selected as collective selection items. In the example of this figure, the selection control unit 33 indicates that the collective selection of the candidate items Ic has been changed to a selected state by adding a marker image including a number indicating the selection order to the upper left of the icon image of the selected candidate items Ic.

[0041] Furthermore, when the selection control unit 33 changes the collectively selected items to a selected state, it performs a display to inform the user that the collectively selected operation has been accepted. Hereinafter, this display will be referred to as a collectively selected display. In the example of Fig. 4, the collectively selected display is performed by setting the check box CB to a checked state. Furthermore, in Fig. 4, the number of candidate items Ic that are in a selected state is shown in the upper right.

[0042] Here, the selection criteria when the selection control unit 33 selects the collectively selected items will be described. The selection control unit 33 determines the collectively selected items based on the values ​​of the focus parameters set for the designated item Id and the multiple candidate items Ic being presented. Specifically, the collectively selected items are determined so that the comparison result between the total value of the focus parameters of the designated item Id and the candidate items Ic selected as the collectively selected items and a predetermined target value satisfies a predetermined condition. In this case, the predetermined target value may be the upper limit value of the focus parameter value obtained by the synthesis process using the designated item Id as the base item. In addition, the predetermined condition that the comparison result should satisfy may be that the total value is equal to or greater than the target value (upper limit value of the focus parameter), or that the total value is the largest value within a range not exceeding the target value (upper limit value of the focus parameter). By selecting the candidate items Ic according to such criteria, the value of the focus parameter of the base item obtained by the synthesis process can be made to reach the upper limit value or to be the largest value within a range not exceeding the upper limit value. When homogeneous synthesis is performed such that the total value of the parameter of interest of the base item and the material item exceeds the upper limit, not all material items are lost, but in addition to the base item whose parameter of interest has reached the upper limit, a material item whose parameter of interest has a value equivalent to the remainder of the parameter of interest exceeding the upper limit may remain. In this way, homogeneous synthesis can be performed without wasting the parameter of interest even under conditions that exceed the upper limit.

[0043] In this case, the selection control unit 33 selects the collectively selected items so that the number of the candidate items Ic selected as the collectively selected items does not exceed a predetermined reference value. As described above, the reference value in this case may be the maximum number of the candidate items Ic that can be selected as the material items for the same type synthesis.

[0044] Furthermore, when selecting collectively selected items according to the above-mentioned selection criteria, the selection control unit 33 selects the collectively selected items according to the order in which the candidate items Ic are displayed on the selection receiving screen S until the above-mentioned conditions are satisfied. In this way, when the collectively selected items are selected, the candidate items Ic are selected in order from the top, so that the user is unlikely to overlook the candidate items Ic that are selected. As described above, if the candidate items Ic are arranged in descending order of the value of the focus parameter on the selection receiving screen S, the selection control unit 33 will preferentially select the candidate items Ic with the larger value of the focus parameter as the collectively selected items. Note that, if it is desired to preferentially select the candidate items Ic with the smaller value of the focus parameter collectively, the candidate items Ic may be arranged in advance in ascending order of the value of the focus parameter. Also, the candidate items Ic on the selection receiving screen S may be rearranged according to a criterion specified by the user. In this case, the selection control unit 33 may select the collectively selected items according to the display order of the candidate items Ic after rearrangement, so that the collectively selected items can be selected according to the criterion desired by the user.

[0045] In the example of FIG. 4, the target value of the total value of the attention parameter is set to 99. When seven candidate items Ic are selected in accordance with the display order, the total value of the attention parameter of the specified item Id and these seven candidate items Ic is less than the target value of 99, but when the next eighth candidate item Ic is also selected in accordance with the display order, the total value is equal to or greater than the target value of 99. Therefore, the selection control unit 33 selects these eight candidate items Ic as the items to be selected in accordance with the display order. Here, as described above, when a material item having a remainder value that exceeds the upper limit value remains due to homogeneous synthesis, the value of the attention parameter of the base item increases to the upper limit value of 99 by homogeneous synthesis using these eight material items, and one material item with a value of the attention parameter of 3 (=total value 102-upper limit value 99) remains. Note that the selection control unit 33 does not necessarily need to select all the collectively selected items in the display order, and may select the ninth candidate item Ic instead of the eighth candidate item Ic as the item to be selected in accordance with the display order, for example, so that the value is closest to the target value.

[0046] As described above, after performing collective selection in response to the collective selection operation of the user, the selection control unit 33 may further receive from the user a selection operation of individual candidate items Ic or a selection operation of changing a selected candidate item Ic to an unselected state. That is, the collective selection operation in this embodiment is not an operation of finalizing the candidate items Ic to be used as material items, but is an operation of simply changing a plurality of candidate items Ic selected according to a given criterion to a selected state in the same manner as when the user performs an operation of selecting the items individually. Therefore, after performing a collective selection operation, the user can arbitrarily select a candidate item Ic to be used as a material item by changing another candidate item Ic to a selected state or returning the collective selected candidate items Ic from a selected state to an unselected state.

[0047] Furthermore, when the user performs an operation to change the candidate items Ic individually to a selected state or to an unselected state after the collective selection operation, and the selected candidate items Ic change from the collective selected items to an unselected state, the selection control unit 33 stops the single selection display. FIG. 5 shows a state in which the user changes the eighth candidate item Ic from the collective selection state shown in FIG. 4 to an unselected state. In this figure, the collective selection display is terminated by unchecking the check box CB. This allows the user to easily understand that the state has changed from the collective selection state.

[0048] According to the client device 10 of this embodiment described above, when performing homogeneous synthesis, it is possible to eliminate the need to individually select multiple candidate items Ic by performing a bulk selection operation, and the user can change the selection of the candidate items Ic that have been selected collectively, thereby enabling the user to select the desired candidate item Ic.

[0049] It should be noted that the embodiment of the present invention is not limited to the above-described embodiment. For example, the screen contents in the above description are merely examples, and the client device 10 may display the selection receiving screen S for allowing the user to select the candidate items Ic in various manners.

[0050] In addition, at least a part of the processing that is to be executed by each of the client device 10 and the server device 20 in the above description may be distributed and executed by a plurality of devices. In addition, in the above description, information on items possessed by the user is managed by the server device 20, but the client device 10 may hold information on the items and notify the server device 20 of the processing results. In addition, the client device 10 may execute all the processing related to the game by itself, in which case the server device 20 may not be required.

[0051] Conversely, at least a part of the processes described above as being executed by the client device 10 may be executed by the server device 20. In particular, the control of arranging the candidate items Ic in the selection receiving screen S and presenting them to the user, and the control of changing each candidate item Ic to a selected state or an unselected state in response to a user's operation may be executed by the server device 20. In this case, the client device 10 transmits the contents of the operation received from the user to the server device 20, and displays an image on the screen of the display device 16 in accordance with an instruction from the server device 20, and the server device 20 functions as an information processing device according to the embodiment of the present invention.

[0052] In addition, the above explanation describes a user interface for selecting material items to be used when performing homogeneous synthesis of items that appear in the game, but the information processing device of this embodiment may also be used to select items to be used for processes other than homogeneous synthesis.
