Abstract

A new form of entertainment is provided in a game having a structure similar to that of a scroll-type shooting game. An input acquisition function acquires input information input by a user on a touch panel. The operation character management function is displayed on the touch panel and controls the operation of the operation character to be operated by the user based on the input information. The enemy character management function is displayed on the touch panel and controls the action of the enemy character attacking the operation character. The distance acquisition function acquires an inter-character distance that is a distance between the operation character and the enemy character. The distance determination function determines whether or not the distance between characters is an approach distance that is equal to or less than a first threshold distance and equal to or greater than a second threshold distance that is shorter than the first threshold distance. The enemy character management function reduces an inter-character distance by bringing an enemy character whose inter-character distance is an approach distance closer to the operation character as time passes.

Description

  The present invention relates to a program, an information processing method, and an information processing apparatus, and more particularly to a technique for providing a game having a configuration similar to a scroll-type shooting game.

  Vertical scroll-type shooting games are widely known. In this type of game, the background of the game screen is scrolled in a direction opposite to the traveling direction of the own device in order to make it appear as if the own device is proceeding forward. In general, these shooting games are operated while the player is controlled to avoid the enemy and the attack bullets released by the enemy, while the enemy is defeated by firing the attack bullets and hitting the enemy.

  There are various types of vertical scrolling shooting games, but most of them are converging on the pattern of “attacking the enemy while avoiding attacks” although there are differences in the way of directing. A game having the same type of configuration as the vertical scroll type shooting game cannot be denied, and it is becoming difficult to appeal the appeal of the game to the user. This problem applies not only to the vertical scroll type shooting game but also to the horizontal scroll type shooting game.

  The present invention has been made in view of such problems, and an object thereof is to provide a new form of entertainment in a game having a configuration similar to a scroll-type shooting game.

  In order to solve the above-described problem, a program according to an aspect of the present invention includes an input acquisition function for acquiring input information input to a touch panel by a user on a computer, and an operation character displayed on the touch panel and to be operated by the user. The operation character management function for controlling the movement based on the input information, the enemy character management function for controlling the movement of the enemy character that attacks the operation character displayed on the touch panel, and the distance between the operation character and the enemy character. A distance acquisition function for acquiring a distance between characters, and determining whether or not the distance between characters is an approach distance that is not more than the first threshold distance and not less than a second threshold distance that is shorter than the first threshold distance. The distance determination function is realized, and the enemy character management function allows the enemy character whose distance between characters is an approach distance to pass Thus close to the operation character, reduce the inter-character distance.

  A vector acquisition function for acquiring a vector defined by a trajectory from the start point to the end point of the movement when the user continuously moves the touch position while touching the touch panel based on the input information acquired by the input acquisition function on the computer. The operation character management function may move the operation character in a direction determined by the vector acquired by the vector acquisition function in accordance with the length of the vector.

  A time measurement function that measures the time during which the distance between characters is close to the computer, and when the time measured by the time measurement function exceeds a predetermined acquisition time, an enemy character is acquired by the operation character. An effect function to be displayed on the touch panel may be further realized.

  The enemy character management function stores and manages the display mode parameter for setting the display mode of the enemy character in the storage unit in association with the enemy character, and sets the display mode parameter of the enemy character whose inter-character distance is the approaching distance as time. You may change according to progress.

  The operation character management function may store and manage the number of enemy characters acquired in the storage unit in association with the operation character, and the distance determination function may change the first threshold distance according to the number of acquisitions.

  The distance determination function further determines whether or not the inter-character distance is a contact distance that is less than the second threshold distance, and the operation character management function is a contact distance that the inter-character distance is less than the second threshold distance. The display mode parameter may be changed, and the presentation function may change the display mode of the operation character displayed on the touch panel according to the display mode parameter of the operation character.

  The operation character management function may change the distance by which the operation character is moved according to the number of acquisitions and the length of the vector acquired by the vector acquisition function.

  The effect function may display on the touch panel how the enemy character acquired by the operation character orbits the operation character.

  The production function (a) scrolls the background of the operation character and the enemy character in the reverse direction of the predetermined direction in order to produce a state in which the operation character and the enemy character advance in the predetermined direction. A background in a region surrounded by a circle having a radius with the first threshold distance as a center may be displayed on the touch panel by changing the luminance value compared to the background outside the circle.

  The effect function further includes at least one of an enemy character and an area close to the enemy character according to a direction approaching the operation character when the enemy character enters the area defined by the first threshold distance and approaches the operation character. The display mode may be changed.

  Another aspect of the present invention is an information processing method. This method includes an input acquisition step of acquiring input information input by the user on the touch panel, an operation character management step of controlling the operation of the operation character displayed on the touch panel and to be operated by the user based on the input information, An enemy character management step for controlling an enemy character that is displayed on the touch panel and attacks the operation character, a distance acquisition step for acquiring a distance between characters that is a distance between the operation character and the enemy character, A distance determination step for determining whether or not the approach distance is equal to or less than a second threshold distance shorter than the first threshold distance and equal to or greater than a second threshold distance. Move the enemy character whose distance is close to the operating character over time Reduce the Yarakuta distance.

  Yet another embodiment of the present invention is an information processing apparatus. The apparatus includes an input acquisition unit that acquires input information input by the user on the touch panel, an operation character management unit that is displayed on the touch panel and controls the operation of the operation character that is the operation target of the user based on the input information, An enemy character management unit that controls an enemy character that attacks the operation character and is displayed on the touch panel; a distance acquisition unit that acquires a distance between characters that is a distance between the operation character and the enemy character; A distance determination unit that determines whether or not it is an approach distance that is equal to or shorter than a first threshold distance and equal to or greater than a second threshold distance that is shorter than the first threshold distance. The enemy character management unit reduces the inter-character distance by bringing the enemy character whose inter-character distance is the approach distance closer to the operation character as time passes.

  It should be noted that any combination of the above-described constituent elements and the expression of the present invention converted between a method, an apparatus, a system, a computer program, a data structure, a recording medium, and the like are also effective as an aspect of the present invention.

  First, an overview of a game provided by an information processing apparatus according to an embodiment will be described with reference to FIG.

  FIG. 1 is a diagram schematically illustrating an example of a game screen provided by the information processing apparatus 100 according to the embodiment. The information processing apparatus 100 according to the embodiment includes an input / output interface 102. Although not limited, as an example, the input / output interface 102 is realized by a touch panel. In the case of the touch panel, input from the user such as user operation and output to the user such as display are realized by the same device. In addition, the input from the user may be realized by using a gesture recognition technique using a camera, a sensor, or the like, and the output may be realized by a general output device such as a liquid crystal or an organic EL panel. In this case, an operation input by an intuitive operation can be realized. Hereinafter, the description will be made on the assumption that the input / output interface 102 is a touch panel. For this reason, the same reference numerals as those of the input / output interface 102 are given and described as “touch panel 102”.

  In the example illustrated in FIG. 1, the information processing apparatus 100 according to the embodiment is a computing device including a touch panel 102 as an input / output interface 102. As an example, the information processing apparatus 100 according to the embodiment can be realized by a smartphone, a tablet PC (Personal Computer), a portable game machine, a notebook PC having a touch panel, or the like.

  The game provided by the information processing apparatus 100 is a game having a configuration similar to that of a scroll-type shooting game. In the example illustrated in FIG. 1, a game screen having the same configuration as that of the vertical scroll shooting game is displayed on the touch panel 102 of the information processing apparatus 100. The user of the information processing apparatus 100 can move the operation character 10 within the game screen by swiping the touch panel. Here, “swipe” means that the user continuously moves the contact position while touching the touch panel 102.

  In FIG. 1, five enemy characters 14 of the first enemy character 14a to the fifth enemy character 14e (hereinafter collectively referred to as “enemy character 14” unless otherwise distinguished) are displayed. The number of enemy characters is not limited to five, and may be more or less. Since the game has a configuration similar to the vertical scroll type shooting game, the background of the game scrolls from the upper part (upper side in FIG. 1) to the lower part (lower side in FIG. 1) of the touch panel 102. Thereby, it appears to the user as if the operation character 10 and the enemy character 14 are traveling in the vertical direction of the game screen.

  The game provided by the information processing apparatus 100 is different from a general shooting game in that the operation character 10 operated by the user cannot attack the enemy character 14 using a missile or other flying tool. Instead, a so-called “attraction zone 12” is set around the operation character 10 to attract the enemy character 14. The user operates the operation character 10 and approaches the attractive area 12 until the enemy character 14 is captured. In FIG. 1, the third enemy character 14 c is captured in the attractive area 12 of the operation character 10.

  The enemy character 14 captured in the attraction zone 12 gradually approaches the operation character 10 due to the attraction of the operation character 10. The enemy character 14 continuously captured by the attractive area 12 is destroyed and acquired by the operation character 10 until a predetermined time elapses. The fragment of the enemy character acquired by the operation character 10 circulates around the operation character 10 as if it were a satellite of the operation character 10.

  Note that the operation character 10 is damaged when it comes into contact with the enemy character 14 before being captured and disassembled by the attractive area 12. Therefore, in order to acquire the enemy character 14, the user who operates the operation character 10 is required to perform an operation of maintaining a certain distance from the enemy character 14 that is the acquisition target of the operation character 10. In this respect, the game provided by the information processing apparatus 100 according to the embodiment is different from a conventional shooting game in which an enemy is attacked from a long distance by a flying tool, and the user has a more precise operation to advance the game. Will be required.

  As the operating character 10 acquires the enemy character 14, the attractive area 12 expands. For this reason, the operation character 10 can attract more enemy characters 14 from a greater distance as the enemy character 14 is acquired. On the other hand, the operation character 10 becomes heavier and gets slower as the enemy character 14 is acquired. In other words, even if the user swipes the touch panel 102 at the same distance, the movement amount and movement speed of the operation character 10 decrease as the enemy character 14 is acquired. Thereby, the user will change the characteristic of the operation character 10 as the game progresses, and the game can be provided with interest.

  Next, the information processing apparatus 100 according to the embodiment and the game provided by the information processing apparatus 100 will be described in more detail.

  FIG. 2 is a diagram schematically illustrating a functional configuration of the information processing apparatus 100 according to the embodiment. Information processing apparatus 100 according to the embodiment includes touch panel 102, control unit 104, and storage unit 130. The control unit 104 includes an input acquisition unit 106, a vector acquisition unit 108, a character management unit 110, a distance acquisition unit 112, a distance determination unit 114, a time measurement unit 116, an effect unit 118, a display area control unit 120, and a change screen display unit 122. And a characteristic management unit 124. The character management unit 110 further includes an operation character management unit 110a and an enemy character management unit 110b.

  FIG. 2 shows a functional configuration for the information processing apparatus 100 according to the embodiment to provide a game, and other configurations are omitted. In FIG. 2, each element described as a functional block for performing various processes can be configured by a CPU (Central Processing Unit), a main memory, and other LSI (Large Scale Integration) in hardware. In terms of software, it is realized by a program loaded in the main memory. Note that this program may be stored in a computer-readable recording medium or downloaded from a network via a communication line. It is understood by those skilled in the art that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof, and is not limited to any one.

  When the function units of the information processing apparatus 100 illustrated in FIG. 2 are realized by software, the information processing apparatus 100 is realized by executing instructions of a program that is software that realizes each function. As a recording medium for storing this program, a “non-temporary tangible medium”, for example, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied via any transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

  The above program uses, for example, a script language such as ActionScript or JavaScript (registered trademark), an object-oriented programming language such as C ++, Objective-C, Java (registered trademark), Ruby, or a markup language such as HTML5. Can be implemented.

  2 is realized using a program, the above-described input acquisition unit 106, vector acquisition unit 108, operation character management unit 110a, enemy character management unit 110b, distance acquisition unit 112, distance determination unit 114, time measurement Unit 116, rendering unit 118, display area control unit 120, change screen display unit 122, and characteristic management unit 124 are respectively input acquisition function, vector acquisition function, operation character management function, enemy character management function, distance acquisition function by computer. It is realized as a distance determination function, a time measurement function, an effect function, a display area control function, a change screen display function, and a characteristic management function.

  The storage unit 130 stores digital data such as an OS (Operating System) for overall control of the information processing apparatus 100, a game program provided to the player, and various parameters referred to by the program. The storage unit 130 can be realized by using a known mass storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The control unit 104 can read information stored in the storage unit 130 and write information to the storage unit 130.

  The input acquisition unit 106 acquires input information input to the touch panel 102 by the user. When the user swipes the touch panel 102 based on the input information acquired by the input acquisition unit 106, the vector acquisition unit 108 acquires a vector defined by a trajectory from the start point to the end point of the swipe. The operation character management unit 110a controls the operation of the operation character 10 to be operated by the user based on the vector 18a that is input information.

  FIG. 3 is a schematic diagram for explaining an operation method of the operation character 10. In FIG. 3, it is assumed that the touch panel 102 is swiped until the user reaches the end point 16b from the start point 16a. At this time, the vector acquisition unit 108 acquires a vector 18a connecting the start point 16a and the end point 16b as input information. At this time, the operation character management unit 110a moves the operation character 10 in the direction determined by the vector 18a acquired by the vector acquisition unit 108 according to the length of the vector 18a. As shown in FIG. 3, the operation character 10 moves based on a vector 18a regardless of whether or not the locus of the touch operation by the user overlaps with the operation character 10.

  As shown in FIG. 3, the operation character management unit 110a moves the operation character 10a to the position of the operation character 10b in the same direction as the direction indicated by the vector 18a. When the length of the vector 18a is long, the operation character 10a increases the movement amount of the operation character 10 compared to the case where the vector 18a is short. In the example illustrated in FIG. 3, the vector 18 a obtained from the user's swipe operation and the vector 18 b that determines the movement amount of the operation character 10 are the same.

  Returning to the description of FIG. The enemy character management unit 110 b is displayed on the touch panel 102, and controls the movement of the enemy character 14 that opposes the operation character 10. More specifically, the enemy character management unit 110b causes the enemy character 14 to attack the operation character 10.

  The display area control unit 120 controls the operation of the virtual camera that generates a display screen including the operation character 10 and the enemy character 14. More specifically, in the virtual game space including the operation character 10 and the enemy character 14, the display area control unit 120 installs a virtual camera at a position where these characters are desired. The rendering unit 118 causes the touch panel 102 to display the video generated by the display area control unit 120 on the virtual camera as a game screen. Therefore, hereinafter, in this specification, the display area control unit 120 is also referred to as “virtual camera control unit 120”.

  The distance acquisition unit 112 acquires an inter-character distance that is a distance between the operation character 10 and the enemy character 14. The distance determination unit 114 determines whether or not the inter-character distance acquired by the distance acquisition unit 112 is an approach distance that is not more than the first threshold distance and not less than the second threshold distance that is shorter than the first threshold distance. To do.

  Here, the “first threshold distance” is a distance that defines an attractive area 12 in which the operation character 10 attracts enemy characters. When the enemy character 14 approaches the attractive area 12 of the operation character 10 (that is, within the first threshold distance), the enemy character 14 is displayed in a form different from the display form in the case other than the attractive area. Specifically, for example, the production unit 118 produces an effect as if the enemy character 14 was captured by attraction, and displayed on the touch panel 102. “Production as if captured by attraction” means, for example, that the enemy character 14 is vibrated and displayed as if trying to escape from attraction. Alternatively, the rendering unit 118 may change at least one of the hue, saturation, brightness, transparency, shape, and the like of the enemy character 14.

  The “second threshold distance” is a contact distance that determines whether or not the operation character 10 has contacted the enemy character 14. The distance determination unit 114 also determines whether or not the inter-character distance is a contact distance that is less than the second threshold distance. When the enemy character 14 comes into contact with the operation character 10, the effect unit 118 provides an effect on the touch panel 102 as if the operation character received damage. The “production as if it was damaged” means displaying in a display mode different from that before the operation character 10a is damaged. Specifically, for example, the production unit 118 indicates that the operation character 10 explodes in flames or pops up information obtained by quantifying the physical strength of the operation character 10. Alternatively, the rendering unit 118 may change at least one of the hue, saturation, brightness, transparency, shape, and the like of the operation character 10.

  These effects are implemented based on the display mode of the operation character character managed by the operation character management unit 110a. When the distance between characters is a contact distance that is less than the second threshold distance, the operation character management unit 110a changes the display mode parameter for setting the display mode of the operation character 10 to “explosive flame-up state”. The effect part 118 changes the display mode of the operation character 10 displayed on the touch panel 102 according to the display mode of the operation character.

  The “approach distance” means a distance at which the enemy character 14 is captured by the attractive force of the operation character 10 and the enemy character 14 is not in contact with the operation character 10. The enemy character management unit 110b brings the enemy character 14 whose inter-character distance is the approach distance closer to the operation character 10 as time passes, and reduces the inter-character distance. Thereby, the user can produce as if the enemy character 14 is attracted by the attraction of the operation character 10. The user is required to perform an operation so that the enemy character 14 does not touch the operation character 10 by swiping the touch panel 102.

  The time measuring unit 116 measures the time during which the distance between characters is the approach distance. When the time measured by the time measuring unit 116 exceeds a predetermined acquisition time, the effect unit 118 displays on the touch panel 102 how the enemy character 14 is acquired by the operation character 10. Here, the “predetermined acquisition time” is a parameter that defines a time condition for the enemy character 14 at an approach distance to be acquired by the operation character 10. The enemy character 14 that remains at the approach distance until the acquisition time elapses is acquired or absorbed by the operation character 10. Thereby, the user who operates the operation character 10 can attack the enemy character 14 that is hostile to the operation character 10. Therefore, it can be said that the game provided by the information processing apparatus 100 according to the embodiment is a game that requires the operation character 10 to be kept at a position without being touched by the enemy character 14.

  As described above, in the information processing apparatus 100 according to the embodiment, the input / output interface is the touch panel 102. The operation for preventing the enemy character 14 from coming into contact with the operation character 10 is more intuitive than the conventional operation by pressing a stick or button, or by an intuitive operation such as swipe using the touch panel 102 or a gesture recognition. It can be said that it has high affinity for various operations. These input methods are realized by means for converting continuous movements of a part of the body including a user's finger and hand into operation information. Since the operation for preventing the enemy character 14 from coming into contact with the operation character 10 requires a fine operation, it can be said that the operation allowing the continuous movement has higher affinity. Further, for example, when the information processing apparatus 100 is realized by an apparatus including a relatively narrow touch panel 102 such as a smartphone, the game screen is inevitably narrowed and the movement area of the operation character 10 is also limited. For this reason, the information processing apparatus 100 according to the embodiment requires a strategy such that the user considers an area that avoids the enemy character 14 and considers how to acquire the enemy character 14 in close proximity. Can provide games.

  The enemy character management unit 110b stores and manages the display mode parameter for setting the display mode of the enemy character 14 in association with the enemy character 14 in the storage unit 130. The “display mode parameter of the enemy character 14” is a parameter that determines the appearance of the enemy character 14 displayed on the touch panel 102. The appearance of the enemy character is, for example, “normal appearance”, “bound appearance”, “destroyed appearance”, or the like. The enemy character management unit 110b changes the display mode of the enemy character 14 in which the distance between characters is the approach distance as time elapses.

  More specifically, the enemy character management unit 110b changes the display mode of the enemy character 14 whose inter-character distance is the approach distance from the normal state to the bound state. Further, when the time measured by the time measuring unit 116 exceeds the acquisition time, the enemy character management unit 110b changes the display mode of the enemy character 14 from the bound state to the destroyed state.

  FIG. 4 is a diagram illustrating a display state of the enemy character 14 and a state in which the enemy character 14 is acquired by the operation character 10. In FIG. 4, the display mode of the enemy character 14 is in a destroyed state. When the display mode parameter of the enemy character 14 is in a destructive state, the rendering unit 118 superimposes an image representing the explosion flame on the enemy character 14 and causes the touch panel 102 to display the superimposed image. In addition, as shown in FIG. 4, the broken pieces 20 of the destroyed enemy character 14 are acquired by the operation character 10. More specifically, the rendering unit 118 causes the touch panel 102 to display a state in which the fragments 20 of the enemy character 14 acquired by the operation character 10 circulate around the operation character 10 like a satellite. Although not limited, as an example, the operating character 10 acquires one piece 20 each time one enemy character 14 is destroyed.

  The operation character management unit 110a stores the number of enemy characters 14 acquired in the storage unit 130 in association with the operation character 10 for management. For example, in the example shown in FIG. 4, the operation character 10 has already acquired 11 enemy characters 14 and shows a scene in which the destroyed enemy character 14 is acquired as the 15th enemy character 14. In this case, the operation character management unit 110a rewrites the number of acquisitions stored in the storage unit 130 from 14 to 15.

  When the operation character 10 acquires the enemy character 14, the mass of the operation character 10 increases. As described above, the first threshold distance is a distance that defines the attractive area 12 in which the operation character 10 attracts enemy characters. Accordingly, when the operation character 10 acquires the enemy character 14, it is natural that the value of the first threshold distance increases. This is because the magnitude of the attractive force of the operation character 10 is proportional to the mass of the operation character 10.

  Therefore, the distance determination unit 114 changes the first threshold distance according to the number of acquisitions. More specifically, the distance determination unit 114 increases the value of the first threshold distance when the number of acquisitions is large compared to the case where the number is small. Thereby, since the enemy character 14 can be bound from a distance far enough to acquire the enemy character 14, the user can easily acquire the enemy character 14. By performing such setting, the user can intuitively understand that the attraction increases by acquiring the enemy character 14.

  On the other hand, it is natural that the operation character 10 becomes difficult to move as the mass of the operation character 10 increases. Therefore, the operation character management unit 110a changes the distance by which the operation character 10 is moved according to the number of acquisitions and the length of the vector 18a acquired by the vector acquisition unit 108. In other words, the operation character management unit 110a adjusts the distance to which the operation character 10 is moved according to the acquired number. More specifically, the operation character management unit 110a reduces the amount of movement of the operation character 10 even when the vector 18a has the same size, as compared to a case where the number of acquisitions is large and the number is small. As a result, the moving speed of the operation character 10 is also reduced. Even if the length of the vector 18a is the same, the movement amount of the operation character 10a decreases as the enemy character 14 is acquired, so that the movement of the operation character 10a becomes dull.

  Therefore, the game is easy in that the enemy character 14 can be bound from a far distance as the enemy character 14 is acquired, but the game becomes difficult in that the movement of the operation character 10 becomes dull. As described above, the game provided by the information processing apparatus 100 according to the embodiment adjusts the gravitational sphere 12 of the operation character 10, that is, the “attack range”, and the mobility of the operation character 10 as a whole. The game balance can be kept. In addition, the user is required to have a strategy to advance the game in consideration of the trade-off between the maneuverability of the operation character 10 and the attack range, so that the interest of the game can be improved.

  As described above, the game provided by the information processing apparatus 100 has the same configuration as the scroll-type shooting game. For this reason, the rendering unit 118 scrolls the background of the operation character 10 and the enemy character 14 in a predetermined direction. Thereby, it is possible to produce a state in which the operation character 10 and the enemy character 14 travel in the reverse direction of the predetermined direction. In addition, the rendering unit 118 causes the touch panel 102 to display a background in a region surrounded by a circle centered on the operation character 10 and having a radius of the first threshold distance as compared with the background outside the circle. Thereby, the user can grasp the attractive area 12 of the operation character 10 at a glance.

  When the enemy character 14 enters the region defined by the first threshold distance and approaches the operation character 10, the effect unit 118 further surrounds a circle whose radius is the first threshold distance according to the direction of approaching the operation character 10. Change the display mode of the area. More specifically, when the enemy character 14 is in the area surrounded by the circle, the rendering unit 118 is a part of the background in the area opposite to the enemy character 14 in the area across the operation character 10. The brightness of the background is reduced and displayed on the touch panel 102.

  FIG. 5 is a diagram showing an effect during the acquisition of the enemy character 14 by the effect unit 118 according to the embodiment. In FIG. 5, the attractive circle 12, that is, the region surrounded by the circle having the radius of the first threshold distance is shown in gray for the sake of convenience, but this region has a higher brightness than the background outside the circle. ing. As shown in FIG. 5, the enemy character 14 is captured in the attractive area 12 of the operation character 10. At this time, the area 22 on the opposite side of the enemy character 14 across the operating character 10 in the attractive area 12 has a different display mode from the other areas. In FIG. 5, the area 22 is shown in lighter gray than the other attractive areas 12, which indicates that the area 22 has lower brightness than the other attractive areas 12.

  Alternatively, instead of changing the luminance, the rendering unit 118 may change at least one of the background hue, saturation, luminance, transparency, pattern, and the like. Further, the rendering unit 118 may change the display mode of the background according to the moving speed of the enemy character 14 existing in the attractive area 12.

  Thus, by changing the display mode of the attraction zone 12 according to the position where the enemy character 14 is captured and displaying it on the touch panel 102, it is possible to provide a more dynamic effect to the user. The touch panel 102 is a device that serves both as an input interface that accepts user operations and an output interface that presents a game screen to the user. Therefore, the display area recognizable by the user on the touch panel 102 is narrowed, and the moving direction of each character may be difficult for the user to recognize. This is more noticeable when the information processing apparatus 100 according to the embodiment is a small device such as a smartphone, because the touch panel 102 is inevitably narrowed. Furthermore, in the game provided by the information processing apparatus 100 according to the present embodiment, the user is required to keep the distance between the operation character 10 and the enemy character 14 at a predetermined distance. For this reason, recognition of the moving direction and moving speed of the enemy character 14 is important information for the user. With the above configuration, the user can easily grasp the moving direction of the enemy character 14, and the user can operate the operation character 10 more appropriately.

  Returning to the description of FIG. The characteristic management unit 124 manages the character characteristics set for the operation character 10 separately from the operation character management unit 110a. Here, the “character characteristic” is a general term for parameters that characterize the behavior of the operation character 10. Character characteristics include the number of acquisitions, the first threshold distance (the size of the attraction area 12), the acquisition time, the magnitude of inertia, the display mode, the size of the operation character 10, the upper limit value of the moving speed, the start dash Includes duration, boost duration, attack attributes, defense attributes, etc.

  As described with reference to FIG. 4, when the operation character 10 acquires the enemy character 14, the enemy character 14 circulates around the operation character 10. For this reason, the size of the operation character 10 varies according to the number of enemy characters 14 acquired. Therefore, when the enemy character 14 is acquired by the operation character 10, the characteristic management unit 124 increases the size set for the operation character 10.

  The virtual camera control unit 120 changes the angle of view of the virtual camera, that is, the display area of the display screen, according to the size set for the operation character 10. More specifically, the virtual camera control unit 120 increases the distance between the virtual camera and the operation character 10 when the size set for the operation character 10 increases. In other words, the virtual camera is pulled to shoot and the angle of view of the virtual camera is expanded. As a result, since the size of the operation character 10 displayed on the touch panel 102 is smaller than the display area of the touch panel 102, it is possible to suppress a decrease in operability of the operation character 10.

  In the game provided by the information processing apparatus 100 according to the embodiment, the operation character 10 can be operated even in a display area other than the operation character 10. For this reason, even if it is a narrow display area like the touch panel 102 of a smart phone, for example, a display object (an operation character 10, a screen display UI (User Interface), or an enemy character 14) is shielded by a user's finger operated. There is an effect that can be operated without being done. However, if the size of the operation character 10 is larger than the display area, the above effect may be weakened. Therefore, in the game provided by the information processing apparatus 100 according to the embodiment, when the display of the operation character 10 becomes larger than the display area of the touch panel 102, the angle of view of the virtual camera is expanded. Thereby, said effect can be maintained. That is, the display range of the operation character 10 with respect to the screen display area can be reduced, and a decrease in user operability can be suppressed.

  By the way, since the operability of the operation character 10 decreases as the number of acquisitions increases, it becomes difficult to avoid the attack of the enemy character 14. If the number acquired is too large, it may be difficult to progress the game.

  Therefore, the operation character management unit 110a accepts an operation for releasing the enemy character 14 acquired by the user. In return for giving up the area of the attraction area 12 of the operation character 10, the user may increase the moving speed of the operation character 10 and advance the game at once. Accordingly, the user is required to select the size of the attractive area 12 of the operation character 10 and the progress of the game, and the game can be more interesting.

  More specifically, the operation character management unit 110a is triggered by the input acquisition unit 106 acquiring input information related to the release of the enemy character 14, and exceeds the upper limit value of the movement speed for a predetermined period. Increase travel speed. During this period, the operation character 10 is invincible, and the game progresses at a stretch. Hereinafter, this state is referred to as a “boost state” for convenience. Further, the time during which the boost state continues is described as “boost duration”.

  The characteristic management unit 124 returns the acquired number set for the operation character 10 to the initial value after the boost duration time has elapsed or during the boost duration time. As a result, the size set for the operation character 10, the upper limit value of the moving speed, the first threshold distance, and the like return to the initial values. The operating character management unit 110a sets the boost duration so that the boost duration becomes longer as the number of acquisitions increases.

  FIGS. 6A to 6B are diagrams showing examples of the game screen when the operation character 10 is in the normal state and in the boost state. Specifically, FIG. 6A is a diagram showing an example of the game screen when the operation character 10 is in the normal state, and FIG. 6B is a diagram showing an example of the game screen when the operation character 10 is in the boost state. It is. FIG. 6A is the same as the game screen shown in FIG.

  When the movement speed is improved as the operation character 10 is in the boost state, the virtual camera control unit 120 changes the angle of view of the virtual camera so that the screen display range in the movement direction of the operation character 10 is widened. For this reason, the operation character 10 is displayed at the lower part of the touch panel 102 as shown in FIG. Further, as shown in FIG. 6B, when the operation character 10 is in the boost state, the virtual camera is installed at a position away from the operation character 10. In other words, when the operation character 10 is in the boost state, the virtual camera control unit 120 generates a game screen by pulling the virtual camera. As a result, the operation character 10 displayed on the touch panel 102 becomes smaller.

  For example, in a state where the speed of the operation character 10 is increased as in the boost state, when a narrow operation region such as the touch panel 102 of the smartphone is used, the user operability regarding the operation character 10 is deteriorated. Therefore, when the moving speed of the operation character 10 increases as in the boost state, the virtual camera control unit 120 changes the angle of view of the virtual camera around the operation character 10 and expands the display area. Thereby, the display area of the game can be expanded, and the area where the operation character 10 can be operated / moved can also be expanded. While increasing the moving speed of the operating character 10, the area in which the operating character 10 can be operated / moved is expanded, so that it is possible to suppress a decrease in user operability. Conversely, when the moving speed of the operation character 10 is reduced, the angle of view may be narrowed.

  Thus, the virtual camera control unit 120 changes the angle of view of the virtual camera according to the moving speed of the operation character 10. When the operation character 10 is in the boost state, the movement speed of the operation character 10 is fast, and the operability of the operation character 10 is reduced. In such a case, by changing the angle of view of the virtual camera to reduce the display size of the operation character 10 and enlarging the display area (enlarging the area in which the operation character 10 can be operated / moved) The operability of the operation character 10 can be maintained. It is also possible to indicate to the user that the operation character 10 is in a special state (that is, a boost state in which the operation character 10 moves at a speed exceeding the upper limit value of the moving speed). Note that the movement speed of the operation character 10 includes not only an increase in the movement speed based on the user's operation, but also an increase in the relative speed with respect to the game field by increasing the scroll speed of the background screen.

  The case where the character characteristic of the operation character 10 is changed when the user operates the operation character 10 to acquire the enemy character 14 has been described above. In addition, the game provided by the information processing apparatus 100 can provide an opportunity for the user to change the initial value of the character characteristics of the operation character 10. Hereinafter, the change of the initial value of the character characteristic of the operation character 10 by the user will be described.

  The change screen display unit 122 causes the touch panel 102 to display a characteristic change screen for changing the initial value of the character characteristic of the operation character 10 in response to the operation of the touch panel 102 by the user.

  FIG. 7 is a diagram showing an example of the characteristic change screen 150 displayed on the touch panel 102 by the change screen display unit 122 according to the embodiment, and is a diagram showing an “evolution map” of the operation character 10. In FIG. 8, the operation character 10 is in an octagonal position indicated by reference numeral 30. The user can move the octagon in the characteristic change screen 150 by consuming predetermined points. For example, when the operation character 10 is in an octagonal position indicated by reference numeral 30, the operation character 10 moves to the first area 34a, the second area 34b, the third area 34c, and the fourth area 34d adjacent to the octagon. can do. If these areas are unreachable areas for the operation character 10, the areas are locked and movement of the operation character 10 is restricted. The user can unlock a locked area by consuming predetermined points. Once unlocked, the area can be moved freely without consuming points. The unlocking of the area and the movement of the operation character 10 on the characteristic change screen 150 are managed by the change screen display unit 122.

  The points used for unlocking the area are given according to the number of acquisitions associated with the operation character 10, that is, the number of enemy characters 14 acquired by the operation character 10. When the user advances the game and clears the stage, the rendering unit 118 causes the touch panel 102 to display a stage clear screen (not shown). On this stage clear screen, points are given to the operation character 10 according to the number of acquisitions. Specifically, the characteristic management unit 124 stores more points in the storage unit 130 in association with the operation character 10 as the number of acquisitions increases.

  In FIG. 7, the operation character 10 reaches the nine evolution forms 32 from the first evolution form 32 a to the ninth evolution form 32 i (hereinafter collectively referred to as “evolution form 32” unless they are distinguished from each other). Possible final evolution forms are shown. When the operation character 10 unlocks the area and reaches one of the evolution forms 32, the initial value of the character characteristics is changed according to the evolution form 32. How the initial value of the character characteristic is changed depends on the evolution form 32 reached by the operation character 10.

  For example, when the operation character 10 reaches the first evolution form 32a, the characteristic management unit 124 increases the initial value of the upper limit value of the moving speed. Thereby, the moving speed of the operation character 10 increases. When the operation character 10 reaches the second evolution form 32b, the characteristic management unit 124 shortens the initial value of the acquisition time required to acquire the enemy character 14. Thereby, the operation character 10 can acquire the enemy character 14 in a short time.

  When the operation character 10 reaches the third evolution form 32c, the characteristic management unit 124 increases the initial value of the first threshold distance. Thereby, the operation character 10 can acquire the enemy character 14 from a distance. When the operation character 10 reaches the fourth evolution mode 32d, the characteristic management unit 124 changes the start dash duration to a value greater than 0 so that the operation character 10 starts a dash at the start of the game. As a result, the operation character 10 can start the game from a position advanced than usual. When the operation character 10 reaches the fifth evolution form 32e, the characteristic management unit 124 increases the initial value of the boost duration. As a result, the operation character 10 can continue the boost state for a longer time than usual.

  When the operation character 10 reaches the sixth evolution form 32f, the characteristic management unit 124 gives an attack attribute to the operation character 10. Here, the “attack attribute” is information indicating the type of influence on the action of the enemy character 14 when the operation character 10 captures the enemy character 14 in the attractive area 12. For example, when the paralysis attribute is given as the attack attribute of the operation character 10, when the operation character 10 captures the enemy character 14 in the attractive area 12, the enemy character management unit 110b is paralyzed and cannot move. Control. Thereby, the operation character 10 can acquire the enemy character 14 more safely.

  When the operation character 10 reaches the seventh evolution form 32g, the characteristic management unit 124 sets the initial value of the number of acquisitions of the operation character 10 to a value larger than zero. Thereby, the operation character 10 has acquired the enemy character 14 from the beginning. As a result, the size and the first threshold distance of the operation character 10 are increased, and the boost can be used from the start of the game.

  When the operation character 10 reaches the eighth evolution form 32h, the characteristic management unit 124 gives a defense attribute to the operation character 10. Here, the “defense attribute” is information for changing the influence when the operation character 10 is attacked by the enemy character 14. For example, when the shield attribute is given as the defense attribute of the operation character 10, even if the operation character 10 is attacked by the enemy character 14, the game is not over the predetermined number of times.

  When the operation character 10 reaches the ninth evolution mode 32i, the characteristic management unit 124 gives any two changes among the first evolution mode 32a to the eighth evolution mode 32h to the operation character 10. The characteristic management unit 124 may cause the user to select a change to be made to the operation character 10 or may select it randomly.

  In any case, the operating character 10 reaches the evolution form 32 by consuming the acquired points and unlocking the area. Accordingly, the range of the initial value of the characteristic that can be changed by the user on the characteristic change screen 150 provided by the change screen display unit 122 is determined according to the number of enemy characters 14 acquired by the operation character 10. The characteristic management unit 124 changes the display mode according to the type of the evolution form 32 when the operation character 10 reaches any evolution form 32. As a result, when the initial value of the character characteristic of the operation character 10 is different, the rendering unit 118 changes the display mode of the operation character 10 and displays it on the touch panel 102. Before starting the game, the user can select the evolved form 32 once reached and change the initial value of the character characteristic of the operation character 10 before executing the game.

  FIG. 8 is a diagram schematically showing a data structure of a character characteristic management table for managing the character characteristics of the operation character 10. The character characteristic management table is stored in the storage unit 130, and is managed jointly by the operation character management unit 110a and the characteristic management unit 124. As shown in FIG. 8, the character characteristic management table stores current values and initial values for various parameters for management in association with the operation character 10. Each unit included in the control unit 104 reads out necessary information from the character characteristic management table with reference to the storage unit 130 and executes processing.

  FIG. 9 is a state transition diagram showing transition of the display screen in the game provided by the information processing apparatus 100 according to the embodiment. When the user starts the game, the rendering unit 118 displays an initial screen on the touch panel 102 (ST1). When the user starts the game by operating the touch panel 102, the rendering unit 118 displays the play screen illustrated in FIG. 1 on the touch panel 102 (ST2). When the user performs an operation of selecting the characteristic change screen 150 on the initial screen, the change screen display unit 122 displays the characteristic change screen 150 illustrated in FIG. 7 on the touch panel 102 (ST3).

  When the user unlocks the area by consuming points on the characteristic change screen 150, the change screen display unit 122 displays an unlock screen (not shown) on the touch panel (ST4). Although not shown, on the unlock screen, a state where the locked area is unlocked is displayed using animation. When this animation ends, the change screen display unit 122 automatically switches the screen displayed on the touch panel 102 to the characteristic change screen 150, and the screen changes to the characteristic change screen.

  When the user unlocks all areas on the characteristic change screen 150, the change screen display unit 122 automatically switches the screen to be displayed on the touch panel 102 to an evolution map complete display screen (not shown) (ST5). Although not shown, the change screen display unit 122 causes the touch panel 102 to display an animation image that praises that all the evolution forms 32 have been reached on the evolution map complete display screen. When the display of the evolution map complete display screen is completed, the change screen display unit 122 automatically switches the screen displayed on the touch panel 102 to the characteristic change screen 150, and the screen changes to the characteristic change screen.

  Although not shown in FIG. 7, an icon indicating that the game is started is displayed on the characteristic change screen 150. When the user taps this icon on the characteristic change screen 150, the screen displayed on the touch panel 102 transitions to the play screen.

  The game provided by the information processing apparatus 100 has a “stage” as a unit of game progress. When the user clears the stage in which the game is progressing on the play screen, the rendering unit 118 changes the screen displayed on the touch panel 102 to the stage clear screen (ST6). Although not shown, points corresponding to the number of acquisitions are displayed on the stage clear screen. The characteristic management unit 124 stores the points acquired by the user in the character characteristic management table in association with the operation character 10.

  When the stage clear screen is displayed on the touch panel 102, the user can transition the display screen to the characteristic change screen 150. Thereby, the user can unlock the locked area on the characteristic change screen 150 using the acquired points. Further, the user can transition the display screen displayed on the touch panel 102 to the play screen again and continue the game.

  FIG. 10 is a flowchart for explaining the flow of enemy character acquisition processing executed by the information processing apparatus 100 according to the embodiment. The process in this flowchart starts when the above-described display screen transitions to a game screen, for example.

  The input acquisition unit 106 acquires input information input to the touch panel 102 by the user (S2). When the user continuously moves the contact position while touching the touch panel 102 based on the input information acquired by the input acquisition unit 106 (that is, when a swipe operation is performed), the vector acquisition unit 108 starts from the start point of the movement. A vector defined by the locus to the end point is acquired (S4).

  The operation character management unit 110a controls the operation of the operation character 10 to be operated by the user based on the input information, and displays it on the touch panel 102 (S6). The enemy character management unit 110b controls the action of the enemy character 14 attacking the operation character 10 and displays it on the touch panel 102 (S8).

  The distance determination unit 114 acquires an inter-character distance Lc that is a distance between the operation character 10 and the enemy character 14 (S10). If the inter-character distance Lc is not the approach distance (N in S12), the process returns to step S10 and the distance determination unit 114 continues to acquire the inter-character distance Lc. When the inter-character distance Lc is the approach distance (Y in S12), the time measuring unit 116 measures the time during which the inter-character distance Lc is the approach distance (S14). The enemy character management unit 110b controls the character whose inter-character distance Lc is the approach distance so as to approach the operation character 10 (S16). While the time measured by the time measuring unit 116 does not pass the acquisition time (N in S18), the process returns to step S10 and the processing up to S16 is continued.

  When the time measured by the time measuring unit 116 has passed the acquisition time (Y in S18), the rendering unit 118 displays on the touch panel 102 how the enemy character 14 has been acquired, and the characteristic management unit 124 acquires the character characteristic management table. The number is increased (S20). When the acquisition of the enemy character 14 ends, the processing in this flowchart ends.

  FIG. 11 is a flowchart for explaining the flow of the game screen creation process executed by the information processing apparatus 100 according to the embodiment. Similarly to the enemy character acquisition process, the process in this flowchart starts, for example, when the above-described display screen transitions to the game screen.

  Steps S2 and S4 are the same as steps S2 and S4 in FIG.

  The virtual camera control unit 120 acquires the display position and moving speed of the operation character 10 from the operation character management unit 110a (S22). The virtual camera control unit 120 acquires the position of the enemy character 14 from the enemy character management unit 110b (S24). The virtual camera control unit 120 installs a virtual camera at a predetermined position in a virtual three-dimensional space for generating a game screen (S26). The virtual camera control unit 120 acquires the characteristic parameter of the operation character 10 with reference to the character characteristic management table (S28). The virtual camera control unit 120 changes the angle of view of the virtual camera based on the acquired characteristic parameter (S30).

  The rendering unit 118 refers to the character characteristic management table and acquires the display mode of the operation character 10 (S32). The rendering unit 118 superimposes the operation character 10 that has been rendered based on the display mode on the video acquired from the virtual camera control unit 120, and displays it on the touch panel 102 as a game screen (S34). When the rendering unit 118 displays a game screen on the touch panel 102, the processing in this flowchart ends. By repeating the above processing, the game screen displayed on the touch panel 102 is updated.

  As described above, according to the information processing apparatus 100 according to the embodiment, in a game having a configuration similar to the scroll-type shooting game, it is possible to provide a new form of entertainment in which an operation character grows while absorbing enemies. it can.

  The user is required to maintain the operation character 10 that is the operation target without leaving the enemy character 14, and can provide the user with new operability that is not found in the conventional shooting game. Further, since the angle of view of the game screen is changed according to the moving speed, size, etc. of the operation character 10, a dynamic effect corresponding to the progress of the game can be provided to the user.

  The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .

  In the above description, the information processing apparatus 100 has been described on the premise of providing a so-called stand-alone game in which the game is executed independently. However, the information processing apparatus 100 does not have to execute the game standalone. For example, a server (not shown) may provide a game, and the information processing apparatus 100 may execute the game by a so-called server / client system that displays the processing result.

(First modification)
FIG. 12 is a schematic diagram illustrating a configuration of a game system 300 including the information processing apparatus 100 and the server 200. In the configuration shown in FIG. 12, some or all of the functions of the control unit 104 shown in FIG. Which function of the control unit 104 shown in FIG. 2 is responsible for the information processing apparatus 100 and which function is responsible for the server 200 may be determined by experiments according to the resources of the information processing apparatus 100. For example, when the resource of the information processing apparatus 100 is poor, only the input acquisition unit 106 can be executed by the information processing apparatus 100, and other functions including the storage unit 130 can be executed by the server 200. In this case, the information processing apparatus 100 transmits the input information acquired by the input acquisition unit 106 to the server 200 via a network such as the Internet. The server 200 executes the game based on the input information, and transmits the processing results of the change screen display unit 122 and the rendering unit 118 to the information processing apparatus 100 via the network. The information processing apparatus 100 displays the acquired processing result on the touch panel 102. Thereby, even if the resource of the information processing apparatus 100 is poor, the user of the information processing apparatus 100 can execute the game.

  When the information processing apparatus 100 has sufficient resources, the information processing apparatus 100 may execute functions other than the input acquisition unit 106. In this case, the load on the server 200 can be reduced.

  In general, it is considered that the user of the information processing apparatus 100 is not interested in whether the functions of the units illustrated in FIG. 2 are executed by the information processing apparatus 100 or the server 200. For the user of the information processing apparatus 100, a game may be realized using at least one of the resource of the information processing apparatus 100 and the resource of the server 200. Here, the calculation resources of the information processing apparatus 100 and the calculation resources of the server 200 are defined as “cloud computing resources”. According to this definition, the present invention may be realized by “cloud computing” by executing the function of each unit described above by “cloud computing resources”. That is, the function of each unit described above may be realized by at least one of the resource of the information processing apparatus 100 and the resource of the server 200.

(Second modification)
In the above, the case where the game provided by the information processing apparatus 100 has the same configuration as that of the vertical scroll type shooting game has been mainly described. The game provided by the information processing apparatus 100 may not have the same configuration as the vertical scrolling shooting game, and may have the same configuration as the horizontal scrolling shooting game, for example. In addition to the scroll-type shooting game, the present invention can be applied to, for example, a vertical or horizontal roll action game, a 3D action game, and a 3D shooting game.

(Third Modification)
The case where the game provided by the information processing apparatus 100 is a two-dimensional scroll type shooting game has been described as an example. The game provided by the information processing apparatus 100 is not limited to two dimensions, and may be a virtual three-dimensional game. In this case, the attraction sphere described above is not a circle but a solid such as a sphere or a solid such as a spheroid. Moreover, even if it is a case where it implement | achieves in two dimensions, the shape of the attractive zone 12 is not restricted to a circular shape. For example, the shape of the attractive area 12 may be a closed curve having an arbitrary shape such as a sector or a triangle.

(Fourth modification)
In the above description, the case where the operation character 10 attacks the enemy character 14 in the game provided by the information processing apparatus 100 has been described. In addition to this, the operation character 10 may have other attack modes. For example, the operating character 10 may be able to make a long distance attack like a conventional shooting game. In this case, since the former attack has a higher risk than the latter attack, the operation character management unit 110a may give the operation character 10 more reward (for example, the points described above).

(Fifth modification)
In the above description, the case where the enemy character 14 can be acquired by attacking the operation character 10 close to the enemy character 14 in the game provided by the information processing apparatus 100 has been described. Instead of this, or in addition to this, there may be an enemy character having a different result caused by the attack by the operation character 10. For example, an enemy character 14 that can be acquired after an attack by the operation character 10 may be mixed with an enemy character 14 that cannot be acquired and is simply added with a score or points. Accordingly, the user is required to have a strategy to advance the game in consideration of the risk of approaching the enemy character 14 for the attack and the reward obtained as a result of the attack, and the interest is improved. Alternatively, the enemy character 14 may not be acquired as an attack result, and a score may be simply added.

(Sixth Modification)
The case where the operation character 10 becomes difficult to move as the operation character 10 is acquired as the enemy character 14 in the game provided by the information processing apparatus 100 has been described above. In addition to this, the operation character 10 may be rendered more difficult to stop as the enemy character 14 is acquired. For example, even if the user's swipe operation ends, the operation character management unit 110a can be realized by moving the operation character 10 in the direction of the latest vector 18 for a predetermined time. Thereby, it is possible to realize an effect of adding inertial force to the operation character 10. The user is required to advance the game in consideration of the movement of the operation character 10 due to the inertial force, and can provide a game that is more interesting.

(Seventh Modification)
The case where the operation character 10 becomes difficult to move as the operation character 10 is acquired as the enemy character 14 in the game provided by the information processing apparatus 100 has been described above. In addition to this, the operation character is triggered by the occurrence of a user action that reduces the virtual mass set for the operation character 10 (for example, an action such as using a predetermined item or receiving an attack from the enemy character 14). The attractive area set to 10 may be narrowed.
