Next, the internal configuration of the controller 7 will be described with reference to FIG. FIG. 5 is a block diagram showing the configuration of the controller 7.
In FIG. 5, the core unit 70 includes a communication unit 75, an acceleration sensor 701, and a vibrator 704 in addition to the operation unit 72 and the imaging information calculation unit 74 described above.

  The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744. The infrared filter 741 allows only infrared light to pass through from light incident from the front of the core unit 70. The lens 742 condenses the infrared light that has passed through the infrared filter 741 and outputs the condensed infrared light to the image sensor 743. The imaging element 743 is a solid-state imaging element such as a CMOS sensor or a CCD, for example, and images the infrared rays collected by the lens 742. Therefore, the image sensor 743 captures only the infrared light that has passed through the infrared filter 741 and generates image data. Image data generated by the image sensor 743 is processed by an image processing circuit 744. Specifically, the image processing circuit 744 processes the image data obtained from the image sensor 743 to detect high-luminance portions, and transmits processing result data indicating the result of detecting their position coordinates and area to the communication unit 75. Output to.

  Note that these imaging information calculation units 74 are fixed to the housing 71 of the core unit 70, and when the direction of the housing 71 itself changes, the imaging direction changes accordingly. Based on the processing result data output from the imaging information calculation unit 74, a signal corresponding to the position and movement of the core unit 70 can be obtained.

  Since the housing 77 of the subunit 76 is connected to the subunit 76 by a connection cable 79 that can be bent, the imaging direction of the imaging information calculation unit 74 changes even if the direction or position of the subunit 76 is changed. do not do. The subunit 76 may be provided with an imaging information calculation unit similar to that of the core unit 70.

  The acceleration sensor 701 is an acceleration sensor that detects acceleration along three axes of the core unit 70 in the vertical direction, the horizontal direction, and the front-rear direction. The acceleration sensor 701 may be an acceleration sensor that detects acceleration on two axes in the vertical direction and the horizontal direction depending on the type of operation signal required. Data indicating the acceleration detected by the acceleration sensor 701 is output to the communication unit 75. The acceleration sensor 701 is typically a capacitance type acceleration sensor, but other types of acceleration sensors or gyro sensors may be used. Based on the acceleration data output from the acceleration sensor 701, the movement of the core unit 70 can be detected.

  The communication unit 75 includes a microcomputer (microcomputer) 751, a memory 752, a wireless module 753, and an antenna 754. The microcomputer 751 controls the wireless module 753 that wirelessly transmits transmission data while using the memory 752 as a storage area during processing.

  An operation signal (core key data) from the operation unit 72 provided in the core unit 70, an acceleration signal (acceleration data) from the acceleration sensor 701, and processing result data from the imaging information calculation unit 74 are output to the microcomputer 751. The In addition, an operation signal (sub key data) from the operation unit 78 provided in the subunit 76 is output to the microcomputer 751 via the connection cable 79. The microcomputer 751 temporarily stores the input data (core key data, sub key data, acceleration data, and processing result data) in the memory 752 as transmission data to be transmitted to the receiving unit 36a.

  Here, the wireless transmission from the communication unit 75 to the receiving unit 36a is performed every predetermined cycle, but since the game processing is generally performed in units of 1/60, a shorter cycle than that is performed. It is necessary to send in. Specifically, the processing unit of the game is 16.7 ms (1/60 seconds), and the transmission interval of the communication unit 75 configured with Bluetooth is 5 ms. When the transmission timing to the receiving unit 36a comes, the microcomputer 751 outputs the transmission data stored in the memory 752 as a series of operation information and outputs it to the wireless module 753. The wireless module 753 radiates operation information from the antenna 754 as a radio wave signal using a carrier wave of a predetermined frequency using, for example, Bluetooth (registered trademark) technology.

  That is, core key data from the operation unit 72 provided in the core unit 70, subkey data from the operation unit 78 provided in the subunit 76, acceleration data from the acceleration sensor 701, and processing from the imaging information calculation unit 74. Result data is transmitted from the core unit 70. Then, the radio signal is received by the receiving unit 36a of the game apparatus 3, and the radio signal is demodulated or decoded by the game apparatus 3, whereby a series of operation information (core key data, sub key data, acceleration data, and processing result data). ) To get. And CPU30 of the game device 3 performs a game process based on the acquired operation information and a game program. Further, the CPU 30 of the game apparatus 3 calculates the position and orientation of the core unit 70 based on the processing result data indicating the position coordinates and area detection results of the LEDs 8L and 8R, the distance between the LEDs 8L and 8R, and the like.

  When the communication unit 75 is configured using the Bluetooth (registered trademark) technology, the communication unit 75 can also have a function of receiving transmission data wirelessly transmitted from other devices.

  The vibrator 704 may be a vibration motor or a solenoid, for example. Since the vibration is generated in the core unit 70 by the operation of the vibrator 704, the vibration is transmitted to the hand of the player holding it, and a so-called vibration-compatible game can be realized.

  The player holds the core unit 70 in such a manner that the thumb of the right hand is attached to the upper surface of the core unit 70 (for example, in the vicinity of the cross key 72a) and the index finger is attached to the concave portion (for example, in the vicinity of the operation button 72i) of the lower surface of the core unit 70. . At this time, the light incident port of the imaging information calculation unit 74 provided on the front surface of the core unit 70 is exposed in the forward direction of the player.

As described above, the core unit 70 can easily operate the operation unit 72 such as the cross key 72a and the operation button 72i while being held by the player with one hand. Further, when the player holds the core unit 70 with one hand, the light incident port of the imaging information calculation unit 74 provided on the front surface of the core unit 70 is exposed, so that the two LED modules 8L and 8R described above are exposed. Infrared light can be easily taken from the light entrance. That is, the player can hold the core unit 70 with one hand without obstructing the function of the imaging information calculation unit 74 of the core unit 70. That is, when the player moves the hand holding the core unit 70 with respect to the display screen, the core unit 70 can further include an operation input in which the movement of the player's hand acts directly on the display screen.
Further, the subunit 76 is also gripped and operated in the same manner by the player's left hand.

  Here, an action game executed in the game system having the above-described configuration will be described. In this game, a player character operated by a player is made to live in a virtual village, and a request to receive an order from a non-player character living in the village (transportation and collection of items, subjugation and capture of a monster (enemy character), etc.) is cleared. It is an action game that progresses depending on the situation.

  A field (hunting ground) to which the player character is directed upon request is composed of a plurality of game stages (hereinafter, stages), and a plurality of “collection points” are set in each stage. The collection point is a point (place) where an item useful for advantageously proceeding with the game can be obtained. A player can collect items from collection points, and can produce or strengthen weapons and armor using the collected items. In addition, the player can create a new item by combining a plurality of collected items, and can produce or strengthen weapons and armor using the collected items.

The game is advanced by performing processing such as activating the character.

  The player character control unit 52 generates a player character in the game space and controls the activity of the player character based on operation information input from the operation detection unit 50. For example, in the field, the player character is moved to a collection point or an item is collected from the collection point.

  The non-player character control unit 53 generates a non-player character in the game space and controls the activity of the non-player character. Non-player characters include monsters (enemy characters) that fight the player characters, and enemy characters also include “guide characters” that guide item collection points. The non-player character control unit 53 controls the activity of the guide character to move the guide character to the item collection point or to have a meal at the collection point.

  The game space control unit 54 generates a game space for the field selected based on the operation information input from the operation detection unit 50, and controls the environment such as weather and day / night changes in the game space. In addition, a plurality of stages are generated in each field, and a plurality of sampling points are set in each stage. Then, the location of the collection point is determined based on a predetermined condition, and the type of item that can be collected at the collection point is determined.

  The drawing processing unit 55 includes a data processing unit such as the CPU 30 and the GPU 32, generates a 3D game space generated by the game progress control unit 51 and a game image in which a character is projected on a 2D screen, and outputs the game image to the monitor 2. . In addition, the drawing processing unit 55 generates an image of a virtual camera that captures the player character and the surrounding game space as an initial game image from behind or slightly above the player character, and displays the image on the monitor 2.

≪Explanation of item pop points≫
As described above, the game space control unit 54 does not fix the location of the collection point from which the player character obtains the item, but randomly determines it by lottery. In addition, the types of items (collected items) that can be collected at each collection point are also determined by lottery. In this way, it is possible to obtain different items at different places every time, thereby expanding the variation of the game and preventing the player from getting bored.

  FIG. 7 is a diagram illustrating a field configured by a plurality of stages generated by the game space control unit 54. The field shown in the figure is composed of four stages 1 to 4, and a plurality of collection points (corresponding to “candidate points” in the present invention) are set in each stage. The collection points are divided into groups of 2 to 3 points in each stage, groups A to C on stage 1, groups D to F on stage 2, groups G and H on stage 3, groups I on stage 4, J exists.

Hereinafter, a method for determining a collection point for causing an item to appear (pop) will be described.
First, a lottery (ON / OFF) is set for each group set for each stage whether or not to provide a collection point (item pop location, corresponding to the “item acquisition point” of the present invention) for popping (generating) an item. decide. That is, the item pop point is a collection point at which an item appears on the ground and the player character can obtain the item. For example, in the case of stage 1, it is determined by lottery such as A group ON, B group OFF, and C group ON. In this embodiment, the probability of ON / OFF of each group is 50%, but an arbitrary probability may be set. This lottery is performed for all stages in the field.

  Next, with respect to the group determined to be provided with an item pop location, one “item pop location” is selected (determined) from among a plurality of collection points belonging to the group. In this embodiment, the winning probabilities as the item pop locations of the respective collection points are made equal. For example, in the case of group A in stage 1, there are two collection points, so the winning probability of each collection point is 50%. This probability may be set arbitrarily. This lottery is performed for all groups determined to have item pop locations in the field. Through the above processing, the item pop location is randomly determined.

  In the embodiment shown in FIG. 7, the collection points are provided in all stages of the field, but may be provided only in some stages. Further, when the field (game space) is not divided into a plurality of stages, the collected points may be distributed over the entire game space or may be distributed over only a part thereof.

  In addition, the distribution form of the collection points of each group on the stage is arbitrary. For example, as shown in stage 3 of FIG. 7, the sampling points of each group may be distributed uniformly throughout the stage. As shown in stages 2 and 4, the sampling points of each group are assigned to each stage. You may collect and distribute in a specific area. Moreover, as shown in the stage 1, these forms may be mixed.

  By uniformly distributing the collection points of a specific group on the stage, items (see the following description) associated with the collection points of the group are randomly collected at various points on the stage. Further, by collecting and distributing the collection points of a specific group in a specific area of the stage, items associated with the collection points of the group are often collected somewhere in the specific area.

Hereinafter, a method of determining the type of the collected item at the item pop location will be described.
First, for each item pop location determined in the above process, the “item table candidate number” is determined using the table corresponding to the group to which the item pop location belongs in the “item table candidate number lottery table” in FIG. . Next, in the “item table lottery table” of FIG. 9, one or more (for example, two) “item tables” in the “item table candidate” column associated with the determined “item table candidate number”. Then, one “item table” to be used is determined. Then, by determining the “item table”, the “type” of the item to be popped is specified, and an image (model) representing the type of the item corresponding to the “item table” is determined by the “model table” in FIG. To do. Furthermore, the “content” of the item that can be acquired when the player character collects an item from this item pop location is determined by the “item table” in FIG.

  FIG. 8 is a diagram showing an “item table candidate number lottery table”. FIG. 4A is the same table for the A group, and FIG. 4B is the same table for the B group. This table is set for each group, and is similarly set for other groups not shown. The “item table candidate number” and “probability” of each group are set to arbitrary values.

  The “item table candidate number” of the “item table candidate number lottery table” in FIG. 8 corresponds to the “item table candidate number” of the “item table lottery table” in FIG. In other words, the “item table candidate number” to be referred to in the “item table lottery table” of FIG. 9 is determined by lottery by the “item table candidate number lottery table” of FIG.

  FIG. 9 is a diagram illustrating an “item table lottery table”. One table is provided for each field. The “item table candidate number” corresponds to the “item table candidate number” of the “item table candidate number lottery table” in FIG. In addition, a plurality of “item tables” are set in “item table candidates”. “Item table” in this column is a candidate for “item table” set in the item pop location, and is set in association with “item table candidate number”. In the present embodiment, “item table candidate number” is associated with one or two “item tables”. “Probability” is the winning probability when determining (lottery) the “item table” to be used from the two “item tables” set in the “item table candidate numbers” 1 to 10.

  For example, a case where “2” of “item table candidate number” is won by lottery by “item table candidate number lottery table” in FIG. In the “item table lottery table” of FIG. 9, “medical table” (“probability” 60%), “ivy table” (“ivy table” (“ Probability "40%) is set. Therefore, among these tables, which table is used (set as an item pop location) is drawn (determined) based on the set “probability”.

  On the other hand, when “11” to “15” of “item table candidate numbers” are won, only one item table is set in “item table candidate”, so this lottery is not performed. Note that the number of item tables of “item table candidates” corresponding to one “item table candidate number” is not limited to 1 or 2, and may be any number.

  Each “item table” of “item table candidate” is associated with a “model number” for specifying a model. A model is an “item image displayed at an item pop location, indicating the type and characteristics of the item. By displaying a model corresponding to the“ item table ”at the item pop location, the item pop is displayed. A player can be informed of the types and characteristics of items that can be collected at a location.

  Furthermore, each “item table” of the “item table candidate” is associated with “maximum number of times of collection” and “number of times of fixed collection” at the item pop location where the item is collected. “Maximum number of times of collection” refers to the maximum number of items that the player character can obtain items at the item pop location. On the other hand, the “determined number of times of collection” refers to the minimum number that the player character can obtain items at the item pop location.

  FIG. 10 shows a “model table” for determining a model to be displayed at the item pop location. The “model number” in this table is associated with the “model number” in the “item table lottery table” in FIG. The “model code” is information for reading an image file of a model, and for example, the file name of the image file is used. The model name, which is the name of each model, is written at the right end of the “model table”. This model name is not included in the “model table”.

  Two types of models, “normal” and “rare”, are set according to their characteristics. In FIG. 10, “real rare”, “grass rare”, “kinocolea”, “bone rare”, “mining rare”, “honey rare”, “insect rare part 1”, “insect rare part 2” are “rare”. All other cases fall under “Normal”.

  As shown in “Item table lottery table” in FIG. 9, two types of “item tables” corresponding to “item table candidate numbers” “1” to “10” are normal items and the other is a rare item. The above-described normal model and rare model are associated with each other. For example, when “item table candidate number” is “2”, two tables of “medicinal herb table” and “ivy table” are set in the “2” column of “item table lottery table”. The “medicinal herb table” corresponds to the normal item in the “grass” model (model number 3), and the “ivy table” corresponds to the rare item in the “grass rare” model (model number 4).

  The player can grasp whether a normal item can be collected at the collection point or a rare item can be collected by looking at the model displayed in the item pop location. As a result, the player can preferentially aim for a high-value “rare pop”.

  In the item pop location, a model is displayed and a transparent object for sound generation is arranged. When the player character touches the transparent object for sound generation, a predetermined sound is emitted. Then, in the case of a transparent object at the item pop location, a sound effect “Casa Kasa” is emitted. The player can recognize from this sound effect that there is an item pop portion near the player character.

  Note that the separation between normal items and rare items is not classified only by the type of item. For example, when “item table candidate number” is “1”, “item table” of “item table candidate” is “honey table”. In this case, both the normal item and rare item tables are the “honey table”, but the “maximum number of times of collection” and “final number of times of collection” are different, and the normal item and the rare item are separated according to the size of these numbers. Is going.

  The separation of the normal item and the rare item is not limited to these cases, and any method that can distinguish the characteristics of the item may be used. In addition, the rare item may be set not only with an item that is more rare and difficult to obtain than a normal item, but also with an item that is less scarce but is very useful for advancing the game.

  When the player presses the A button 72d while the player character is in the vicinity of the item pop location, the player character performs a collection action motion and obtains an item. Thereby, the number of times of collection “1” is counted. Then, after the number of collections reaches the fixed number of collections, a lottery is performed to determine whether or not to keep the item pop location every time. If it is decided to continue here, the player character can collect an item at the item pop location next time. On the other hand, when it is determined to disappear, the item pop portion disappears together with the model, and the player character cannot collect items at the item pop portion. Also, when the maximum number of collections is reached, the item pop location is forcibly disappeared.

  The content of the item that the player character actually obtains is determined by lottery using the “item table” selected for the item pop location each time the player character takes a collecting action.

FIG. 11 is a diagram showing a part of a plurality of “item tables” for determining the contents of items actually obtained by the player character.
Each “item table” is associated with “item table candidates” in FIG. This table is provided for all “item tables” included in the “item table candidates” in FIG. 9, and is similarly set for other tables not shown. Note that “item name” and “probability” in each table are set to arbitrary values.

  In each table, item names and winning probabilities of items actually obtained by the player character are set. For example, in the case of (B) “medicinal herb table”, “medicine herb” is set to 60%, “Ikitsugi algae” is set to 32%, and “paint fruit” is set to 8%. Then, the player character obtains the winning item by lottery based on the probability set in each table. For example, ID information for specifying an item is set in the “item name”.

  In the embodiment shown in FIG. 8 to FIG. 11, the items collected at each item pop location are drawn using three types of tables: an item table candidate number lottery table, an item table lottery table, and an item table. In this way, by using the three types of tables to draw the items collected at the item pop location, the item table candidate number lottery table and the item table lottery table are used to collect the points (item pop locations) for each group. The items collected in (1) can be classified (trendd), and the items actually collected can be randomly determined within the category using the item table.

  In addition, the determination method of the item extract | collected in each item pop location is not limited to the method of drawing lots using the said 3 types of table. For example, one item associated with each group may be collected from the item pop location of the group in which one item is associated with each group and the item pop location is provided. Also, one item table is associated with each group, and any item registered in one item table associated with the group from the item pop location of the group that is supposed to provide the item pop location. May be collected.

  FIG. 12 is a flowchart showing an item pop setting process performed by the game space control unit 54. As described above, the item pop setting process is a process of performing lottery of the item pop location and the item table as time elapses.

  By resetting the item pop location as time passes, not only the item pop location is changed every time the player character goes to the field, but also the item pop location is changed according to the stay in the field. Therefore, it is possible to realize a game that is more varied.

  First, it is determined whether or not the game is started (S11). If the game is not started (NO in S11), it is determined whether or not the update timer is equal to or greater than a predetermined value (S12). The update timer is a timer that measures an elapsed time after setting the item pop location. When the update timer is less than the predetermined time (NO in S12), the process here is not performed. On the other hand, if the update timer is equal to or longer than the predetermined time (YES in S12), all item pop locations currently set in the field are deleted in order to update the item pop locations (S13).

  After erasing the item pop portion in S13 or at the start of the game (YES in S11), it is first determined by lottery for all groups in the field whether to pop the item for each group (S14). Next, for the group determined to pop the item in S14, one item pop point is set by lottery from a plurality of predetermined collection points (S15). Next, in each item pop location set in S15, an item table candidate number to be referred is determined by lottery from the item table candidate number lottery table (FIG. 8) for each group to which the item pop belongs (S16).

  Next, in the item table lottery table, an item table to be used is determined by lottery from among a plurality of item tables corresponding to the item table candidate numbers determined in S16 (S17). Next, a model corresponding to the item table determined in S17, the maximum number of collections, and the number of fixed collections are set for each item pop location determined in S15 (S18). Next, in order to measure the elapsed time after setting the item pop location, the update timer is reset (S19).

≪Guide character explanation≫
In the present invention, the item pop setting process is performed and the setting location of the item pop location changes. Therefore, a “guide character” which is a non-player character is provided, and the guide character is moved to the item pop location so that the player can Inform the location. Thereby, it becomes easy for a player to find an item pop part, and the difficulty level of a game is prevented from becoming too high by moving an item pop part at random.

  In this embodiment, an “ant” character is provided as a guide character. Hereinafter, the behavior of the guide character will be described using “ant” as an example. An ant is set to either “normal state” or “battle state”, and the ant acts based on the state.

  The normal state is a state in which ants are not attacked and perform normal actions. On the other hand, the battle state is a state in which ants are under attack and perform battle actions. When an ant in the normal state is attacked, it switches to the battle state, and returns to the normal state if it is not attacked for a certain period of time in the battle state. However, when an ant is attacked in the normal state, if it has already finished “meal” and is hungry, it will be switched to the battle state, but it will be forced to do not perform the battle action Processing to escape to the nest is performed. The ant meal will be described later.

  In addition, whether or not to switch from the normal state to the battle state is centrally managed by the entire ants in the stage. In other words, if any one ant is attacked, all ants in that stage are in combat. Therefore, if one ant is attacked, all the ants will attack as a group, and the ecology of the group of ants can be expressed realistically.

  In the behavior of ants in the normal state, in addition to the behavior determined by the lottery based on the behavior lottery table (FIG. 13), the behavior of craving around the nest, the foraging behavior (moving to the item pop location and eating the item Eating action, homing action to return to the nest after eating). On the other hand, most of ants' behavior in the battle state is determined by lottery based on the behavior lottery table (FIG. 13).

  FIG. 13 is an action lottery table for determining ant actions. (A) and (B) are action lottery tables in the normal state, (A) is used for action lottery 1 (S32 in FIG. 15), and (B) is used for action lottery 2 (S35 in FIG. 15). . In the action lottery 1, “intimidation” is set to 10%, “sniff” is set to 85%, and “going to normal pop” is set to 5%. On the other hand, in the action lottery 2, “intimidation” is set to 10%, “sniffing” is set to 90%, and “going to normal pop” is not set. In this way, in the normal state, the combat action is not performed, and the normal action such as threatening is performed while moving. As described above, the behavior of the ants in the normal state is not limited to that set in this table, and the lottery by this table is performed only in a predetermined case (FIG. 15).

  FIGS. 13C to 13E are action lottery tables in the battle state, and are divided into three tables for each distance between an ant and an enemy character (player character, other non-player character). This figure is used when (C) is a very short distance, (D) is a short distance, and (E) is a distance other than the above (medium distance or more). Specific numerical values for each distance can be arbitrarily set. In the battle state, for example, as shown in (C), in addition to “intimidation” and “run” behaviors, battle behaviors such as “biting attack” and “formic acid attack” are performed.

  FIG. 14A is an image diagram showing a behavior of an ant. Ants perform foraging behavior when an item pop appears in the normal state. For item pops where normal items are popped (hereinafter referred to as “normal pops”), foraging behavior is performed only when “go to normal pop” is selected in the action lottery, but rare items pop For the item pop location (hereinafter referred to as “rare pop”), foraging is always performed in preference to all behavior.

  Ants roam around the initial set position 102 set near the nest 101. The initial set position is an initial arrangement position when an ant is arranged in the game space at the start of the game, and is located around the nest. However, the initial set position 102 is different for each individual. When the item pop location appears, the ant moves from the initial set position 102 toward the item pop location (starts foraging behavior).

  In the present embodiment, ants react only to three item types: “mushroom (mushroom)”, “real (real rare)”, and “honey (honey rare)”. Therefore, even if an item pop location where an item of a kind that the ant does not respond to appears, the ant continues normal behavior except foraging behavior. This distinguishes between items that an actual ant can eat and items that cannot be eaten. Note that the item type to which the guide character reacts (performs foraging behavior) can be arbitrarily set together with the form of the guide character.

  When an ant arrives at a normal pop or a rare pop, he performs a “meal” to eat the items there. And when ants eat, the ant's belly swells, and the color of the swelled belly changes depending on the contents of the pops eaten. Specifically, in the case of “Mushrooms”, in blue for “Real Rare”, in green for “Rare”, in yellow for “Honey Rare”, for normal pop (“Mushroom” “Real” “Honey”) Each changes to gray. In addition, the color to change can be set arbitrarily and you may change the form of a part of ant's body other than a color.

  Moreover, it may replace with an ant eating, and you may make it carry an item. In this case, without changing the shape of the ants, for example, a display mode may be adopted in which an item is carried by carrying a colored spherical object on the back of the ants.

  Depending on the eating behavior of the ants, the number of times the item pops are collected is not counted, and the number of times of collection is counted only by the collecting behavior of the player character. Therefore, even if an ant eats, the item pop part remains without disappearing. The ant whose shape of the belly has changed after eating returns to the nest 101.

  Here, when the player character attacks and defeats the ant with the belly inflated, the ant drops an item corresponding to the color of the belly around him. The player character can obtain the item by picking it up. More specifically, a sparkling effect image is displayed at the place where the item is dropped, and if the player character performs a collecting action in the vicinity thereof, the collecting motion is reproduced and a lottery is performed. The item corresponding to the lottery result is obtained.

  In this case, if the ant's belly is gray, the item that the ant drops will drop a special "disappearing item", but if the belly color is blue, green or yellow, a special "winning item" will be dropped . Then, with respect to those winning items, by referring to a dedicated lottery table (not shown) corresponding to the color, a lottery is performed at the timing when the player character picks up the item, and an item to be specifically obtained is determined.

  FIG. 14B is an image diagram illustrating an ant movement path. As described above, the ants are set at the initial set position 102 at the start of the game, and are on the inside of a circle having a radius of 10 m with the initial set position 102 as the center until a pop appears. In this way, it is possible to express how ants roam around the nest.

  Then, when a rare pop appears, or when a normal pop appears and wins by action lottery, movement is started toward the pop that has appeared. The destination normal pop corresponds to the “destination normal pop (corresponds to the“ ordinary item acquisition point ”of the present invention)”, and the destination rare pop corresponds to the “destination rare pop (the“ rare item acquisition point ”of the present invention). .) ”.

  Priorities are set between rare pops to which ants react. In this embodiment, the priorities are in order of kino correa 114 (high), real rare 116 (medium), and honey rare 112 (low). Therefore, when a plurality of different types of rare pops appear at the same time, a rare pop with a high priority is set as a destination rare pop and moved toward it. For example, when an ant is at a traveling point 94, which will be described later, out of the kino correa 114 and the real rare 116 that can be directly accessed from that point, the kino correa is determined as the destination rare pop. In the present embodiment, for the normal pop, the destination normal pop is randomly determined by lottery and the priority order is not set, but it may be set similarly.

  When the destination (usually rare) pop is determined, the ant moves in a straight line toward the destination when there is no obstacle between the current location and the destination pop. Obstacles are cliffs and walls that restrict the movement of ants. For example, if the current location is 103, the honey 111 and honey rare 112 move in a straight line because there is no obstacle between them.

  On the other hand, if there is an obstacle between the current location and the destination pop, it cannot move in a straight line, so it moves while following the “touring point” set in advance on the stage. A traveling point refers to a plurality of designated coordinates set so as to be able to go straight from any point to all item pop locations in the area. In the stage of FIG. 5B, five traveling points 91 to 95 are provided, and ants follow each point in the order of (1) to (9) shown in the figure. Then, if the traveling point is moved and a point where there is no obstacle between the destination pop and the destination pop is reached, it moves in a straight line from that point toward the destination pop.

  For example, if the destination pop is mushroom 113 or mushroom colle 114, the ant moves the traveling point from the current value 103 in the order of 91, 92, 93, and when it reaches the traveling point 93, it goes to mushroom 113 or mushroom corre 114 from there. Move in a straight line.

  Hereinafter, the process of moving ants to normal pops and rare pops will be described with reference to the flowcharts of FIGS.

FIG. 15 is a flowchart showing ant action control in a normal state performed by the non-player character control unit 53. This process is performed for all ants in the stage.
First, the ant moves toward a randomly designated point within 3 m from the current location (S31). This movement corresponds to a habit. After the movement, the action lottery 1 (FIG. 13A) is performed (S32). As a result of the action lottery 1, when “go to normal pop” is won (YES in S33), it is determined whether or not a normal pop has occurred in the stage (S34). If a normal pop has occurred in the stage (YES in S34), a movement process to a normal pop is performed (S35), and a homing process is performed (S36). The movement process to the normal pop will be described later with reference to FIG. 16, and the homing process will be described later with reference to FIG.

  As a result of the action lottery 1 (S32), even if “go to normal pop” is won, there is no normal pop in the stage, or all items that can be acquired from the normal pop by the player character If all the samples have been collected (NO in S34), the action lottery 2 (FIG. 13B) is performed (S37). In the action lottery 2, the option “go to normal pop” is removed.

  As a result of the action lottery 1 (S32), when “go to normal pop” is not won (NO in S33), or when a normal pop has not occurred in the stage (NO in S34), The ant is caused to perform an action corresponding to the action won as a result of the action lottery 1 (S32) or the action lottery 2 (S37) ("intimidation" or "sniff") (reproduce the motion) (S38).

  Next, it is determined whether or not the distance between the current location of the ants and the initial set position exceeds 10 m (S39). If the ant's current location and the initial set position do not exceed 10m (NO in S39), no processing is performed because the ant is near the nest, but the ant's current location and the initial set position exceed 10m. If it is present (YES in S39), the ants are moved at a moving speed faster than the moving speed for moving to a random position within 10 m from the initial set position (S40).

FIG. 16 is a flowchart showing the process of moving the ants to the normal pop in the normal state (S35 in FIG. 15) performed by the non-player character control unit 53.
First, all normal pops occurring in the stage at the start of this process are listed (S51). Next, ant move destination normal pops are randomly drawn from the listed normal pops and determined (S52). Next, the position coordinates of the destination normal pop determined in S52 are acquired (S53).

  Next, it is determined whether there is an obstacle between the current location of the ant and the destination normal pop (S54). Specifically, when the current location of the ant and the destination normal pop are connected with a straight line, it is determined whether or not a polygon for contact determination of a cliff or a wall exists on the straight line. If there is an obstacle between the current location of the ant and the destination normal pop (YES in S54), the ant is moved to the next tour point (S55). The ant searches for a tour point that can go straight to the destination normal pop while passing through the tour points in a preset order. In the first state, since the ants are wandering around the nest, they move from the nest to the nearest traveling point (for example, the traveling point 91 in FIG. 14B).

  Next, when the ant reaches the patrol point, it is determined whether or not the destination normal pop has disappeared (S56). If the destination normal pop has disappeared (YES in S56), the process here ends. This is because the destination normal pop itself, which is the destination, has disappeared due to the item pop setting process (FIG. 12) over time and the player character having exhausted in the course of the ants traveling around. This is done to determine whether or not.

  If the destination normal pop has not disappeared (NO in S56), it is determined whether there is an obstacle between the current tour point and the destination normal pop (S57). If there is an obstacle between the current tour point and the destination normal pop (YES in S57), the ant is moved to the next tour point (S55) until a tour point that can go straight to the destination normal pop is found. The processes of S55 to S57 are repeated.

  By the above processing, if a place without an obstacle is found before the destination normal pop (NO in S54, NO in S57), the ants are moved to the position coordinates of the destination normal pop (S58). If the ant has moved to the position coordinates of the destination normal pop, it is determined whether or not the destination normal pop has disappeared (S59). This is performed to determine whether or not the destination normal pop has disappeared before the ant moves from the current location or the traveling point to the location of the destination normal pop. If the destination normal pop has disappeared (YES in S59), the process here ends.

  On the other hand, when the destination normal pop has not disappeared (NO in S59), the ant plays a special motion for eating the item in the normal pop and changes the color of the ant's belly to the color corresponding to the eaten item. Further, the scale of the ant belly is enlarged to show that the ant belly is swollen (S60).

  FIG. 17 is a flowchart showing a process of moving an ant to a rare pop in a normal state performed by the non-player character control unit 53. This process is performed for all ants in the stage where the generated rare pop exists when the rare pop occurs.

  When a rare pop occurs, in order to more clearly inform the player that the rare pop has occurred, the ants are quickly moved to the rare pop in preference to all other actions. Therefore, when a rare pop is included in the pop items updated by the item pop setting process (FIG. 12), the current ant action is canceled and the following process is performed.

  First, all the generated rare pops are listed, and the respective position coordinates are acquired (S61). Next, it is determined whether there is a rare pop with no obstacle between the current position (S62). When there is a rare pop with no obstacle between the current position (YES in S62), the rare pop is determined as a destination rare pop (S63). At this time, when there are a plurality of rare pops (without obstacles) that can be directly accessed, one destination rare pop is determined with reference to the above-mentioned priority order.

  Next, the ant is moved to the position coordinate of the determined destination rare pop (S64). When the ants move to the position coordinates of the destination rare pop, it is determined whether or not the destination rare pop has disappeared (S65). If the destination rare pop has not disappeared (NO in S65), the ant plays a dedicated motion for eating the item in the rare pop and changes the color and scale of the ant belly (S66).

  On the other hand, if the destination rare pop has disappeared (YES in S65), it is determined whether there is (other) rare pop in the stage (S67). If there is a rare pop in the stage (YES in S67), the process returns to S61, and the processes after S61 are repeated. If the ant has eaten (S66), or if there is no rare pop in the stage in S67 (NO in S67), a homing process is performed (S68), and the process here ends.

  If there is no rare pop with no obstacle between the current location in S62 (NO in S62), the ants are moved to the next tour point (S69). At this time, if the ants are wandering around the nest, the ants are moved from the nest to the nearest traveling point (for example, the traveling point 91 in FIG. 14B). On the other hand, when moving between the traveling points for the normal pop search, it is moved to the traveling point set in the next order.

  When the ants arrive at the patrol point, it is determined whether or not there is a rare pop in the stage (S70). If there is no rare pop in the stage (NO in S70), the ant loses the destination, so a homing process is performed (S68), and the process here ends. On the other hand, if there is a rare pop in the stage (YES in S70), it is determined whether or not there is a rare pop with no obstacle between the current traveling point (S71). If there is a rare pop with no obstacle between the current traveling point (YES in S71), the process proceeds to S63, and the processes after S63 described above are performed.

  On the other hand, when there is no rare pop without an obstacle between the current tour point (NO in S71), it is determined whether there is a next tour point (S72). If there is a next tour point (YES in S72), the process returns to S69, the ants are moved to the next tour point, and the processing of S69 to S72 is repeated. If there is no next tour point (NO in S72), the ants are moved to the initial set position (S73). This is because if the processing of S69 to S72 is repeated during the tour, the ants reach the final tour point. In this case, the ants are moved from the last tour point to the initial set position, and the process here is terminated.

  As mentioned above, by letting ants take the foraging behavior to move to the item pop location (normal pop / rare pop), the player is informed of the location of the item pop location and prevents the difficulty of the game from becoming too high. be able to. Further, by performing the process of moving to the rare pop with priority over the process of moving to the normal pop, it is possible to reliably notify the player of the occurrence and location of the rare pop and prevent the rare items with high rare value from being missed.

FIG. 18 is a flowchart showing an ant homing process (S36 in FIG. 15, S68 in FIG. 17) performed by the non-player character control unit 53.
The homing process is a process of returning the ants to the nest, and is performed when the ants eat or when the destination (usually rare) pop disappears and the destination is lost.

  First, the nest position coordinates are acquired (S81), and it is determined whether there is an obstacle between the current location and the nest (S82). If there is no obstacle between the current location and the nest (NO in S82), the ants are moved to the nest position coordinates (S83). The determination of the obstacle in the process of S82 may be performed in the same manner as the process of S54 in FIG.

  On the other hand, if there is an obstacle between the current location and the nest (YES in S82), the patrolling point closest to the nest where the ant can go straight from the current location is searched (S84). Next, an ant is moved to the traveling point as a result of S84 (S85). This process is done to get ants back to their nest as soon as possible. When the ant arrives at the tour point, it is determined whether there is a next visit point (S86). If there is a next visit point (YES at S86), the ant is moved to the next visit point (S87). If there is no next tour point (NO in S86), the ants are moved to the nest position coordinates (S83).

  For example, in FIG. 14B, when an ant eats 114 rare mushrooms, the position of the nest (S81), it is not possible to go to the nest 101 in a straight line (YES in S82), so the ant is the current location (rare pop 114) The nearest tour point that can be reached in a straight line from the nest is searched (S84). Specifically, “the nearest traveling point 91 from the nest cannot go straight from the rare pop 114. The next nearest traveling point 92 cannot go straight from the rare pop 114. However, the next nearest traveling point 93 goes straight from the rare pop 114. As a result of “can go by” is obtained, the ants are linearly moved from the rare pop 114 to the traveling point 93 (S85). Thereafter, the ants are moved in the order of the circulation points 93, 92, 91 (S86, S87), and finally the ants are moved to the nest (S83).

  When the ants return to the nest, they will come out of the nest with the belly returned to its original position (original color and size) after a predetermined time. Then, after moving to the initial set position given to the ant, the process described in FIG. 15 is performed on the ant.

  In this embodiment, “Ari” has been described as an example of the guide character, but a character other than “Ari” may be used. Further, the method of notifying the player of the item pop location is not limited to the method by moving the character.

  Also, the “lost item” dropped when an ant (guide character) is attacked may be the item itself ate. In this case, when an ant eats or when a player character picks up a lost item, it can be realized by a method such as performing a lottery using an item table of a pop part.

  In addition, the present invention is not limited to the case where it is realized by a single game machine, and can also be applied to an online game that is performed by communication connection between game machines at remote locations via a communication line and a server. . In this case, the item pop setting process described above can be performed simultaneously for all game machines, and the item pop locations can be synchronized.

  Also, the item to be popped may be the item itself, not the item pop location where the item is available. Furthermore, what is to be popped does not have to be an item, but may be anything that appears in the game space. For example, in an underwater game, the structure which makes a fish guide the place with oxygen may be sufficient.
