Description

  The present invention relates to a game system, and more particularly to a game system using a touch panel as an input device.

Conventionally, game devices that play using an input device other than a controller including cross keys and buttons have been proposed. For example, there is a game system that plays by attacking enemy characters in a game using a sword-shaped controller (see, for example, Patent Document 1). In this game system, the position of the sword-shaped controller and the amount of change in the position per unit time are detected by sensors, and the amount of damage caused to the enemy character by the attack is the speed of swinging the controller or the size of the swing width. It is decided according to. As a result, the player can obtain a feeling that the enemy character in the game is attacked with a sword.
JP 2003-79943 A

  In the above game system, the magnitude of damage given to the enemy character is determined according to the speed at which the sword-shaped controller is swung and the magnitude of the swing width. However, the attack method is only a sword attack, and there are few attack variations. With such a simple attack method, the game itself becomes monotonous and the game is easily bored by the player. That is, since one type of attack is uniquely performed by a single input, there is a problem that the player is easily bored. In particular, in recent games, in addition to direct attacks by swords, various attack methods are possible by performing a magic attack, specifying the magnitude of damage and the range affected by the attack, etc. It is important to keep the game from getting bored.

  Therefore, an object of the present invention is to provide a game system capable of providing a variety of game playing methods to a player by enabling various game operations.

The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses, supplementary explanations, and the like indicate correspondence with embodiments to be described later in order to help understanding of the present invention, and do not limit the present invention.
According to a first aspect of the present invention , a game image is displayed on a computer of a game apparatus (1) that displays a game image on a display screen (first LCD 11) and performs processing based on a position on the display screen input by a player. CPU core 21 for executing control means (S41 (abbreviation of step 11; the same applies to the following)). Hereinafter, only the step number is shown. (S66) A game program that functions as an attack type determining means (S65), an attack power determining means (S67), and a characteristic parameter changing means (S77). The game image display control means displays a game image including game characters (enemy characters 31 and 32) on the display screen. Coordinate detection means stores in a memory of the game apparatus to detect a coordinate value indicating a position where input by the player is performed on the display screen. The shape specifying means reads a plurality of coordinate values from the memory , and specifies the graphic shape of the input locus indicated by the read coordinate value group (input coordinate list 22a). The size calculating means calculates the size of the graphic shape of the input trajectory indicated by the read coordinate value group. The attack type determining means reads information that associates the graphic shape of the input trajectory with the attack type from the memory, and refers to the information to specify the type of attack (attack pattern) against the game character by the shape specifying means. The determination is made based on the formed graphic shape. The attack power determination means reads information that associates the value for determining the attack power with the size of the input trajectory from the memory, and refers to the information to calculate the attack power against the game character by the magnitude calculation means. Determine based on the size. Characteristic parameter change is to update by changing based on characteristic parameters of the game character stored in the memory in the type and attack power of the attack.

Further, the game program may further cause the computer to function as character selection means (S71). The character selection means reads a process of selecting a game character whose characteristic parameter should be changed from the game characters displayed on the display screen based on the area on the display screen determined based on the input trajectory. Execute using the set of coordinate values . At this time, the characteristic parameter changing means changes only the characteristic parameter of the game character selected by the character selecting means.

In addition, the second invention displays a game image on the display screen (first LCD 11), and controls the computer of the game apparatus (1) that performs processing based on the position on the display screen input by the player. This is a game program that functions as means (S41), coordinate detection means (S53), shape identification means (S64), character selection means (S71), attack type determination means (S65), and characteristic parameter change means (S77). The game image display control means displays a game image including game characters (enemy characters 31 and 32) on the display screen. Coordinate detection means stores in a memory of the game apparatus to detect a coordinate value indicating a position where input by the player is performed on the display screen. The shape specifying means reads a plurality of the coordinate values from the memory , and specifies the graphic shape of the input locus indicated by the read coordinate value group (input coordinate list 22a). The character selection means , based on the area on the display screen determined based on the input trajectory, out of the game characters displayed on the display screen, the characteristic parameters indicating the characteristics of the game character (HP and HP of the enemy character). the process of decene the game character to be changed to MP), is performed using the read coordinate value group. The attack type determining means reads information associating the graphic shape of the input trajectory with the attack type from the memory and refers to the information to determine the attack type (attack pattern) against the game character by the shape specifying means. Determine based on the identified graphical shape. Characteristic parameter change is key Yarakuta reads characteristic parameters of elected game character by selecting means from the memory, to update varied based on the type of the attack.

The game program may further cause the computer to function as size calculation means (S66) and attack power determination means (S67). The size calculating means calculates the size of the graphic shape of the input trajectory indicated by the read coordinate value group. The attack power determination means reads information that associates the value for determining the attack power with the size of the input trajectory from the memory, refers to the information, and calculates the attack power against the game character by the magnitude calculation means. Determine based on the size. In this case, the characteristic parameter change means changes the characteristic parameter of the game character based on the attack power determined by attack power determining means.

  The characteristic parameter changing means may change the degree of change of the characteristic parameter in accordance with the number of game characters selected by the character selecting means.

The game program may further cause the computer to function as change display giving means (S76). The change display providing means displays a different effect display on the display screen according to the type of attack determined by the graphic shape of the input trajectory after the graphic shape of the input trajectory is specified by the shape specifying means.

The game program may further cause the computer to function as a trajectory display control means (S56). The trajectory display control means displays the input trajectory at a position on the display screen corresponding to the coordinate value group stored in the memory .

Further, the memory of the game apparatus may store a plurality of reference graphic data indicating the type of attack and indicating a predetermined shape. At this time, the attack type determining means reads the reference graphic data from the memory, and selects the reference graphic data indicating the shape closest to the shape indicated by the coordinate value group from the plurality of reference graphic data stored in the game device. Then, the shape of the selected reference graphic data is determined as the graphic shape of the input trajectory.

  The present invention is a game device comprising storage means (WRAM 22 or cartridge 17) storing the above game program and program execution means (CPU core 21) for executing the game program stored in the storage means. May be provided.

According to the first aspect of the present invention, the basic condition for changing (increasing or decreasing) the characteristic parameter of the game character based on the graphic shape of the input trajectory that is a single input by the player and its size, and the degree of application thereof. Therefore, it is possible to add various changes to the characteristic parameters by a simpler input operation. Further, since to enter the graphical shape on a display screen of the game character is displayed, the more accurate and intuitive input operations can be performed on the player. Here, the basic conditions are, for example, an attack pattern such as magic when attacking an enemy character or an attack type other than magic or a combination thereof, or a magic type that restores the physical strength of the own character. . Therefore, for example, by applying the first invention to a game in which an enemy character is attacked and battles, more various attack patterns can be realized. In other words, according to the first aspect of the invention, it is possible to provide the player with various ways of playing the game by enabling various game operations. In particular, compared to the game system disclosed in Patent Document 1 and the conventional game system in which the battle scene is a command input type, the game is not monotonous and can provide a game with an intuitive operational feeling.

When the computer further functions as a character selection means, the game characters for which the characteristic parameters are changed are not necessarily all game characters displayed on the display screen, but are determined based on the input trajectory. It is determined by the area on the display screen. In other words, the target game character whose characteristic parameter is to be changed changes according to the input position on the display screen , so that the game processing according to the input operation becomes more diverse and the game is more interesting.

According to the second aspect of the invention, the target game character whose characteristic parameter is to be changed and the characteristic parameter are changed (increased or decreased) based on the graphic shape of the input trajectory that is a single input by the player and its position. ) Is determined, and various changes can be made by a simpler input operation. Accordingly, in the second invention as well, as in the first invention, by applying the first invention to a game in which an enemy character is attacked and battles, various attacks can be performed according to various input operations on the display screen. Pattern can be done. That is, according to the second invention, by enabling various game operations, it is possible to provide the player with various ways to play the game, and to provide a game that does not make the player bored.

  When the degree of change in the characteristic parameter changes according to the number of game characters selected by the character selection means, the characteristic parameter depends not only on the shape of the input trajectory but also on the position of the game character on the display screen. The degree of change will change. Accordingly, even when the player performs the same input operation, the game development is different, so that it is possible to provide more various ways to play the game. In addition, since the player needs to perform not only his own input operation but also the input operation paying attention to the position of the game character on the display screen, the game becomes more complicated and the difficulty of the game can be increased. . Therefore, it is possible to provide a game that does not become monotonous and timeless.

  Further, when the computer further functions as a change display giving means, a visual effect that changes according to the basic conditions can be given to the player, and the fun of the game can be increased. That is, it is possible to show the player the change of the game image corresponding to the graphic shape of the input locus. Furthermore, the player can visually and intuitively know what input operation he / she has performed. Therefore, the player can easily confirm whether or not the desired input operation has been performed.

  When the computer further functions as a trajectory display control unit, the result of the input operation by the player is displayed on the screen. Therefore, the player can easily know what input operation he / she has performed. Therefore, the player can easily confirm whether or not the desired input operation has been performed.

  When a plurality of reference graphic data is stored in the game device, the graphic shape of the input trajectory can be easily specified.

When the computer further functions as a vector data group calculating unit and a correcting unit, the shape of the trajectory drawn on the display screen by the player is simplified by the correcting unit. Therefore, since the process of comparing the vector data group and the reference graphic data is simplified, the processing speed can be increased and the processing load on the computer can be reduced.

In role-playing games (RPG) and simulation RPG, it is used for instruction input such as item acquisition and weapon or command selection decision. The direction indicating switch 14c is used for indicating a direction on the game screen such as instructing a moving direction of a player object (or a player character) that can be operated by the player, or instructing a moving direction of the cursor. Further, if necessary, operation switches may be further added, or side switches 14f and 14g may be provided on the left and right of the upper surface (upper side surface) of the operation switch 14 mounting region in the lower housing 18a.

  A touch panel 13 (broken line area in FIG. 1) is attached to the upper surface of the first LCD 11. The touch panel 13 may be, for example, any of a resistive film type, an optical type (infrared type), and a capacitive coupling type, and an upper surface of the touch panel 13 is pressed, moved, or stroked with a stick 16 (or a finger). When this is done, the coordinate position of the stick 16 is detected and coordinate data is output.

  In the vicinity of the side surface of the upper housing 18b, a storage hole 15b (a two-dot broken line region in FIG. 1) for storing the stick 16 for operating the touch panel 13 as necessary is formed. The stick 16 is stored in the storage hole 15b. In a part of the side surface of the lower housing 18a, a cartridge insertion portion (for inserting a game cartridge 17 (hereinafter simply referred to as a cartridge 17) having a built-in memory (for example, ROM) storing a game program in a detachable manner. A one-dot broken line region in FIG. 1) is formed. The cartridge 17 is an information storage medium for storing a game program, and for example, a nonvolatile semiconductor memory such as a ROM or a flash memory is used. A connector (see FIG. 2) for electrical connection with the cartridge 17 is built in the cartridge insertion portion. Furthermore, an electronic circuit board on which various electronic components such as a CPU are mounted is accommodated in the lower housing 18a (or the upper housing 18b). The information storage medium for storing the game program is not limited to the non-volatile semiconductor memory, but may be a CD-ROM, a DVD, or an optical disk storage medium similar to them.

  Next, the internal configuration of the game apparatus 1 will be described with reference to FIG. FIG. 2 is a block diagram showing the internal configuration of the game apparatus 1.

  In FIG. 2, a CPU core 21 is mounted on the electronic circuit board housed in the housing 18. A connector 28 for connecting to the cartridge 17 is connected to the CPU core 21 via a predetermined bus, an input / output interface (I / F) circuit 27, a first graphic processing unit (first GPU). 24, a second graphics processing unit (second GPU) 26, and a working RAM (WRAM) 22 are connected.

  The cartridge 17 is detachably connected to the connector 28. The cartridge 17 is a storage medium for storing the game program as described above. Specifically, the cartridge 17 includes a ROM 171 for storing the game program and a RAM 172 for storing backup data in a rewritable manner. The game program stored in the ROM 171 of the cartridge 17 is loaded into the WRAM 22, and the game program loaded into the WRAM 22 is executed by the CPU core 21. Temporary data obtained by the CPU core 21 executing the game program and data for generating an image are stored in the WRAM 22.

  The touch panel 13, the operation switch unit 14, and the speaker 15 are connected to the I / F circuit 27. The speaker 15 is disposed at an inner position of the sound release hole 15b described above.

A first video RAM (hereinafter “VRAM”) 23 is connected to the first GPU 24, and a second video RAM (hereinafter “VRAM”) 25 is connected to the second GPU 26. 1st GPU
24 generates a first game image based on data for generating an image stored in the WRAM 22 in accordance with an instruction from the CPU core 21, and draws the first game image on the first VRAM 23. In response to an instruction from the CPU core 21, the second GPU 26 generates a second game image based on data for generating an image stored in the WRAM 22 and draws it in the second VRAM 25.

  The first VRAM 23 is connected to the first LCD 11, and the second VRAM 25 is connected to the second LCD 12. The first GPU 24 outputs the first game image drawn in the first VRAM 23 in response to an instruction from the CPU core 21 to the first LCD 11. Then, the first LCD 11 displays the first game image output from the first GPU 24. The second GPU 26 outputs the second game image drawn in the second VRAM 25 in response to an instruction from the CPU core 21 to the second LCD 12. Then, the second LCD 12 displays the second game image output from the second GPU 26.

  Hereinafter, the game process executed in the game apparatus 1 by the game program stored in the cartridge 17 will be described. In the present invention, only the first LCD 11 whose display screen is covered by the touch panel is used as the display device. Therefore, the game device according to the present invention may be configured without the second LCD 12. In other words, the game device according to the present invention can be realized by executing a game program according to the present invention by a game device, a PDA, or the like configured by only one display device.

  First, an outline of a game performed in the game apparatus 1 will be described with reference to FIGS. FIG. 3 is a diagram illustrating an example of a game image displayed on the display screen of the first LCD 11. Hereinafter, any kind of game may be performed on the game device according to the present invention, but in the present embodiment, a role playing game as shown in FIG. 3 will be described as an example. In this role-playing game, there are a moving scene (FIG. 3A) in which the player character operated by the player moves on the game map, and a battle scene in which the player character battles the enemy character (FIG. 3B). . In a moving scene, when a predetermined condition for the player character to encounter an enemy character is satisfied, as shown in FIG. 3A, the display of “An enemy has appeared!” Is displayed, and the game image is displayed in FIG. It switches to the battle scene as shown in (b). In the battle scene, the enemy character and the characteristic parameters of the player character and the enemy character are displayed. In FIG. 3B, two enemy characters, enemy characters 31 and 32, are displayed. Here, the characteristic parameter is a value indicating the characteristic of the game character appearing in the game. Specifically, the player character's HP (hit points) and MP (magic points) and the enemy character's HP and MP are displayed on the first LCD 11 as characteristic parameters. When the game image is switched to the battle scene, the battle advances as the player character and the enemy character attack each other.

  FIG. 4 is a diagram illustrating an example of a game image when the player is performing an attack operation. When the turn in which the player character attacks during the battle, the player performs an attack operation using the touch panel 13. FIG. 4A shows an example of a game image when the player is performing an attack operation. As illustrated in FIG. 4A, the player performs an operation of moving a finger (or the stick 16) on the touch panel 13. At this time, the player performs an operation so that the trajectory of moving the finger has a predetermined shape (a reference graphic to be described later). This locus indicates a position where an input is made by the player on the touch panel 13, and this locus is hereinafter referred to as an input locus. The predetermined shape is determined in advance, and is assumed to be a circle, a triangle, a quadrangle, or the like here. That is, the player performs an operation by moving a finger on the touch panel 13 so that the input locus becomes a triangle or a rectangle. Note that the alternate long and short dash line shown in FIG. 4A is a line indicating how the player's finger has moved.

Further, an input trajectory display 33 indicating the input trajectory is displayed on the game image (dotted line shown in FIG. 4A). The input trajectory is displayed at a position on the display screen corresponding to the position where input is performed on the touch panel 13. That is, the input trajectory display 33 is displayed on the touch panel 13 at the position where the player has actually moved the finger. In FIG. 4A, it can be seen that the input trajectory has a shape close to a circle. The input track display 33 allows the player to clearly and intuitively know the input track by his input operation. Therefore, the player can immediately know whether or not the input locus has a desired shape.

  FIG. 4B is a diagram illustrating an example of a game image after the player performs an attack operation. In the present embodiment, an attack by the player character is performed on the enemy character included in the area surrounded by the input locus. That is, in FIG. 4, the enemy character 31 receives damage from the attack by the player character. If there is no enemy character in the area surrounded by the input locus, the attack by the player character fails. When the attack by the player character is successful, an effect display 34 representing an attack on the enemy character 31 is displayed. Further, a damage display 35 indicating the magnitude of damage given to the enemy character 31 by the attack is displayed. At this time, the game apparatus 1 changes HP, which is a characteristic parameter of the enemy character 31. In the example of FIG. 4B, the HP of the enemy character 31 is subtracted by 90.

  In FIG. 4A, it is preferable that the enemy characters 31 and 32 are moved in the display area. This is because it becomes difficult to surround the attack target with the input trajectory by moving the enemy characters 31 and 32 that are attack targets (targets to be surrounded by the input trajectory), so the game becomes more interesting.

  In this embodiment, the attack pattern by the player character changes according to the shape of the input trajectory. Note that the shape of the input trajectory means the shape of a figure drawn by the input trajectory. The attack pattern is a type of attack by the player character. For example, the type of attack differs between a sword attack and a magic attack. Furthermore, even with the same magical attack, the type of attack differs between the attack with the magic of fire and the attack with the magic of water. FIG. 5 is a diagram illustrating an example of a game image when the input locus is a triangle. In the present embodiment, it is assumed that the player character performs an attack by wind magic when the player performs an input operation such that the input locus is a triangle. In FIG. 5, since the enemy character 31 is moving outside the area surrounded by the triangular input locus, the attack fails. FIG. 6 is a diagram illustrating an example of a game image when the input locus is a quadrangle. In the present embodiment, it is assumed that the player character performs an attack by the magic of water when the player performs an input operation such that the input locus becomes a square. When the player performs an input operation such that the input locus is circular (see FIG. 4), it is assumed that the player character performs an attack with the magic of fire. As described above, in this embodiment, the attack pattern changes depending on the shape of the input trajectory. Therefore, the player can perform various attack patterns by drawing input loci of various shapes on the touch panel 13.

In the present embodiment, the damage given to the enemy character changes according to the size of the shape of the input trajectory. FIG. 7 is a diagram illustrating an example of a game image when attacking a plurality of enemy characters. FIG. 7A shows an example of a game image when the player is performing an attack operation. In FIG. 7A, the shape size of the input trajectory is larger than that in FIG. In FIG. 7A, two enemy characters 31 and 32 are surrounded by an input locus. Accordingly, the two enemy characters 31 and 32 are attacked by the player character. FIG. 7B is a diagram illustrating an example of a game image after the player performs an attack operation. In FIG. 7B, the damage given to one enemy character has changed compared to FIG. 4B. Specifically, the damage given to one enemy character in FIG. 7B is less than in the case of FIG. 4B. Thus, in this embodiment, the damage that can be given to one enemy character by an attack is assumed to decrease as the size of the shape of the input trajectory increases.

  In the present embodiment, it is assumed that the type of the effect display 34 changes according to the attack pattern of the player character. FIG. 8 is a diagram illustrating an example of a game image after the player performs an attack operation. FIG. 8A shows a game image when the player character makes an attack with the magic of flame. In FIG. 8A, an effect display 34 a representing that the enemy character 31 has been attacked with flame is displayed on the display screen of the first LCD 11. On the other hand, FIG. 8B is a game image when the player character makes an attack with a sword. In FIG. 8B, an effect display 34 b representing that the enemy character 31 is cut with a sword is displayed on the display screen of the first LCD 11. Thus, by changing the effect display according to the attack pattern, the player can visually know what kind of attack the input operation performed by the player is. That is, the player can visually confirm whether or not the input operation performed by the player is a desired operation.

  Next, details of the game process executed by the game apparatus 1 will be described. First, data stored in the WRAM 22 during game processing will be described. FIG. 9 is a diagram showing a memory map of the WRAM 22 of the game apparatus 1. During the game process, the WRAM 22 stores an input coordinate list 22a, a vector data list 22b, input trajectory data 22c, a reference graphic database 22d, a damage determination table 22e, enemy character attribute data 22f, and the like. In addition to these data, the WRAM 22 stores game programs and game image data read from the cartridge 17.

  The input coordinate list 22a is data indicating a set of coordinate values (coordinate value group) indicating the position on the touch panel where the input by the player has been made. In this embodiment, the position on the touch panel input by the player is detected at predetermined unit time intervals. The coordinate value indicating the detected position is stored in the WRAM 22 as one list while the player's input continues (while the player's finger or the like is not away from the touch panel).

  The vector data list 22b is data indicating a set of vector data (vector data group) indicating the distance and direction between adjacent coordinate values among the coordinate values stored in the input coordinate list 22a. The vector data list 22b is calculated from the input coordinate list 22a.

  The input trajectory data 22c is data in which a plurality of vector data in which the same direction continues among vector data stored in the vector data list 22b is collectively expressed as one vector data. That is, the input trajectory data 22c can be calculated from the vector data list 22b.

The reference graphic database 22d is data composed of a plurality of reference graphic data. The reference graphic data is data indicating a reference graphic set in association with the attack pattern of the player character. The reference figure data is provided in a number corresponding to the attack pattern of the player character. The reference graphic database 22d is typically stored in the cartridge 17 together with the game program, and is read from the cartridge 17 into the WRAM 22 at the start of the game process. In the present embodiment, the reference graphic data is composed of a plurality of vector data, like the vector data list 22b and the input trajectory data 22c. In the following description of the game process, reference graphic data indicating a circle corresponding to a fire magic attack, reference graphic data indicating a triangle corresponding to a wind magic attack, and a square corresponding to a water magic attack In the following description, it is assumed that the reference graphic data indicating the above is included in the reference graphic database 22d.

  The damage determination table 22e is a table for determining damage to the enemy character based on the attack pattern, the size of the input trajectory, and the attribute of the enemy character that is the attack target. The size of the input trajectory means the size of a figure drawn by the input trajectory. The attribute of the enemy character is a parameter indicating strength against a certain attack pattern, such as being strong against a fire magic attack and weak against a wind magic attack. Specifically, there are water attributes, fire attributes, and the like as attribute types, and an enemy character with a water attribute is weak against a magic attack of fire, but strong against a magic attack of water. The enemy character with fire attribute is weak against the magic attack of water, but strong against the magic attack of fire.

  The enemy character state data 22f is data indicating the state of the enemy character. In the present embodiment, the enemy character state data 22f includes HP and MP, which are characteristic parameters of the enemy character, and data indicating the attributes. When the enemy character is attacked by the player character, the HP of the enemy character stored in the WRAM 22 is subtracted. When the enemy character's HP becomes 0, the enemy character is defeated. In addition to the enemy character state data 22f, the WRAM 22 also stores data indicating the state of the player character. Further, the WRAM 22 stores various data used in the game process in addition to the data shown in FIG.

  Next, the flow of game processing executed in the game apparatus 1 will be described with reference to FIGS. FIG. 10 is a flowchart showing a flow of game processing executed in the game apparatus 1. When the power of the game apparatus 1 is turned on, the CPU core 21 of the game apparatus 1 executes a start program stored in a boot ROM (not shown), and each unit such as the WRAM 22 is initialized. Then, the game program stored in the cartridge 17 is read into the WRAM 22 and the execution of the game program is started. As a result, a game image is displayed on the first LCD 11 via the first GPU 36, so that the game is started. The flowchart shown in FIG. 10 shows the game process after the game image is switched to the battle scene. That is, when the battle between the player character and the enemy character is started in the game after the game starts, the processing of the flowchart shown in FIG. 10 is started. In the present embodiment, the game process in a situation other than the battle scene is not directly related to the present invention, and the description thereof will be omitted.

  In FIG. 10, first, in step 41 (“step” in the figure is simply abbreviated as “S”), the enemy character, the characteristic parameter of the enemy character, and the characteristic parameter of the player character are displayed on the display screen of the first LCD 11. (See FIG. 4B.) Here, it is assumed that HP and MP are displayed as the characteristic parameters of the enemy character and the player character. In the following step 42, it is determined whether or not the player character has made an attack turn. The attack turn is determined according to a predetermined rule. Any rule may be used, but here, it is assumed that the attack turn of the player character and the attack turn of the enemy character are alternated.

  If it is determined in step 42 that it is not an attack turn of the player character, the process of step 43 is performed. That is, in step 43, the enemy character attacks the player character. Specifically, the values of the characteristic parameters (HP and MP) of the player character change according to the attack by the enemy character. That is, the value of the characteristic parameter of the player character stored in the WRAM 22 is updated. After step 43, step 44 is performed.

  On the other hand, if it is determined in step 42 that the attack turn of the player character, in steps 44 to 46, the player character attacks the enemy character. First, in step 44, input detection processing to the touch panel 13 is performed. The input detection process to the touch panel 13 is a process for detecting an input to the touch panel 13 by the player, and a process for creating the input coordinate list 22a. Hereinafter, the input detection process to the touch panel 13 is demonstrated using FIGS.

  FIG. 11 is a flowchart showing a detailed processing flow of step 44 shown in FIG. First, in step 51, the input coordinate list 22a of the WRAM 22 is initialized. Specifically, a memory area capable of storing a predetermined number of coordinate values is secured in the WRAM 22. At this time, the coordinate value indicating the input position by the player is not written in the input coordinate list 22a. In a succeeding step 52, it is determined whether or not an input to the touch panel 13 is detected. When the player performs any operation on the touch panel 13 (that is, when the player touches the touch panel 13), an input to the touch panel 13 is detected, and the process of step 53 is performed. On the other hand, if the player has not performed any operation on the touch panel 13, the input to the touch panel 13 is not detected, and the process returns to step 52. That is, the process of step 52 is repeated until the player performs some operation on the touch panel 13.

  The processes in steps S53 to S57 are processes for detecting the input position of the touch panel 13. The input coordinate list 22a is created by the processes of steps S53 to S57. Hereinafter, the outline of the processing of steps S53 to S57 will be described with reference to FIGS.

  FIG. 12 is a diagram schematically illustrating a state in which an input is performed on the touch panel. In FIG. 12, it is assumed that the player has performed an input operation to draw a dotted input locus shown in the figure. In response to this input operation, the game apparatus 1 detects the position input by the player at predetermined unit time intervals. A white circle illustrated in FIG. 12 indicates a position (detection point) where an input to the touch panel 13 is detected.

  In FIG. 12, after the detection point p1 is first detected, subsequent detection points p2, detection points p3,... Are sequentially detected. In FIG. 12, the vertical axis is the y-axis (downward in FIG. 12 is the positive direction), the horizontal axis is the x-axis (rightward in FIG. 12 is the positive direction), and the top left vertex of the touch panel 13 is the origin. The number of detection points is n (n is an arbitrary integer), the coordinate value of the detection point p1 is (80, 40), the coordinate value of the detection point p2 is (77, 42), and the coordinate of the detection point p3 The value is (75, 45).

  FIG. 13 shows an input coordinate list 22a created when an input as shown in FIG. 12 is made by the player. As shown in FIG. 13, the input coordinate list 22a stores detected coordinate values in the order of detection. Specifically, the coordinate value (80, 40) of the detection point p1 is stored first, the coordinate value (77, 42) of the detection point p2 is stored second, and the coordinate value (75, 40) of the detection point p3 is stored. 45) is stored third. As described above, the coordinate values of the detected points are sequentially stored in the input coordinate list 22a. In FIG. 13, n coordinate values corresponding to the number of detection points are stored.

  In FIG. 12, after the nth detection point pn is detected, the input to the touch panel 13 by the player is not detected. As a result, the creation of the input coordinate list 22a in which n coordinate values are stored is completed. The input coordinate list 22a created in this way indicates an input trajectory during continuous input to the touch panel 13. Hereinafter, details of the processing of steps S53 to S57 will be described.

  Returning to the description of FIG. 11, in step 53, an input to the touch panel 13 is detected at predetermined unit time intervals. Specifically, the coordinate value indicating the position on the touch panel 13 where the input by the player is performed is sent from the touch panel 13 to the CPU core 21. In the following step 54, it is determined whether or not the coordinate value detected in step 53 is the same as the previous value. If it is determined that the values are the same, the processing in steps 55 and 56 is not necessary and is skipped, and the processing in step 57 is performed.

  On the other hand, if it is determined that the coordinate value detected in step 54 is not the same as the previous value, the process of step 55 is performed. That is, in step 55, the coordinate values detected in step 53 are added to the input coordinate list 22a in time series. That is, the coordinate values detected in step 53 are stored so as to be the next input order after the input order in which the coordinate values detected in the previous step 53 are stored (see FIG. 13).

  Following step 55, in step 56, the input locus display 33 (FIG. 4A) is displayed at a position on the display screen corresponding to the position indicated by the coordinate value detected in step 53. Specifically, a line connecting the position indicated by the coordinate value detected in the previous step 53 and the position indicated by the coordinate value detected in the immediately preceding step 53 is displayed on the first LCD 11. After step 56, the process of step 57 is performed.

  In step 57, it is determined whether or not an input to the touch panel 13 by the player continues. Here, that the input continues means that the player's finger is not separated from the touch panel 13. That is, when the player's finger is not separated from the touch panel 13 at the time of step 57, an input to the touch panel 13 is detected, so it is determined that the input continues. In this case, the process of step 53 is performed. Therefore, while the input to the touch panel 13 by the player continues, the processing of steps 53 to 57 is repeated. On the other hand, if the player's finger is away from the touch panel 13 at the time of step 57, the input to the touch panel 13 is not detected, so it is determined that the input has not continued. In this case, the CPU core 21 ends the input detection process to the touch panel shown in FIG.

  Returning to the description of FIG. 10, after step 44, attack content determination processing shown in step 45 is performed. The attack content determination process is a process of determining an attack pattern, an attack target, and an attack power based on the shape, size, and position of the input trajectory. Details of the attack pattern determination process will be described below with reference to FIGS.

  FIG. 14 is a flowchart showing the detailed processing flow of step 45 shown in FIG. Here, the process of steps 61 and 62 shown in FIG. 14 is a process for simplifying the information of the input coordinate list 22 a created in step 44. Since the input coordinate list 22a is a set of coordinate values, it is difficult to specify the shape of the input locus as it is. Steps 61 and 62 are performed for the purpose of making it easier to specify the shape of the input trajectory by processing the information in the input coordinate list 22a. First, the outline of the processing of steps 61 and 62 will be described.

  FIG. 15 is a diagram for explaining processing for simplifying the input coordinate list 22a. FIG. 15A is a diagram schematically showing a group of coordinate values in the input coordinate list 22a. As described above, the input coordinate list 22a is a coordinate value indicating a position on the touch panel 13 detected at a predetermined unit time interval. The detection points p1, p2, and p3 shown in FIG. 15 correspond to the coordinate values stored in the input coordinate list 22a, respectively. In the processing of steps 61 and 62, first, a vector data list 22b is created from the input coordinate list 22a.

  FIG. 15B is a diagram schematically showing the vector data list 22b. Each vector data in the vector data list 22b is a vector connecting adjacent detection points. For example, the vector v1 shown in FIG. 15B is a vector connecting the detection point p1 and the detection point p2. This vector is calculated so as to be the direction in which the player's input operation is performed, that is, the direction from the previously detected detection point to the subsequently detected point. Then, by calculating all vector data connecting adjacent detection points, a vector data list 22b is created (step 61 described later). The vector data stored in the vector data list 22b is represented by eight types of directions. For example, the direction from the detection point p1 to the detection point p2 may be slightly different from the direction from the detection point p2 to the detection point p3. However, since the information about the direction is simplified when the vector data is created, the vector v1 and the vector v2 are processed as the same direction.

  In the processing of steps 61 and 62, next, input trajectory data 22c is created based on the vector data list 22b. Specifically, vector data in which the same direction continues among vector data stored in the vector data list 22b is collected into one vector data. FIG. 15C is a diagram schematically showing the input trajectory data 22c. Here, in FIG. 15B, since the vectors v1 to v5 are in the same direction, these five vectors are combined into one vector. As a result, in FIG. 15C, one side of the triangle of the input trajectory is represented by one vector v'1. Similarly, for the other sides, vectors pointing in the same direction are combined into one vector. As a result, in the input trajectory data 22c, the input trajectory is expressed by three vector data. Accordingly, since the input trajectory data 22c is composed of three vector data, it can be easily determined that the input trajectory is a triangle in FIG. As described above, the processing of steps 61 and 62 can greatly simplify and express the information of the input trajectory, and can easily specify the shape of the input trajectory.

  In addition, when the unit time interval which detects the input of the touch panel 13 is long, or when the speed which a player traces the touch panel 13 is high, there exists a possibility that the position used as the vertex of an input locus cannot be detected. In this case, as shown in FIG. 16A, vector data v different from the actual input locus (dotted line shown in FIG. 16A) is calculated. As a result, the input trajectory data 22c is composed of four vector data (FIG. 16B), and there is a possibility that erroneous recognition such as determining that the input trajectory is, for example, a quadrangle may occur. In order to prevent this, in addition to the processes in steps 61 and 62, a correction process for deleting vector data equal to or less than a predetermined distance from the vector data stored in the input trajectory data 22c may be performed. As a result, vector data different from the actual input trajectory, which is generated when the position that is the vertex of the input trajectory is not detected, is deleted, so that erroneous recognition of the shape can be prevented.

  Returning to the description of FIG. 14, the processing of steps 61 and 62 will be described in detail below. First, in step 61, vector data indicating a vector connecting adjacent coordinate values is calculated based on the coordinate value group in the input coordinate list 22a (see FIG. 15B). A vector data list 22b is created by calculating all vector data connecting adjacent detection points. It should be noted that the vector data connecting the i-th coordinate value (i is a natural number equal to or less than n−1) and the i + 1-th coordinate value in the input order is stored in the i-th vector data list 22b.

FIG. 17 is a diagram for explaining the vector data list 22b. FIG. 17A is a diagram illustrating an example of the vector data list 22b obtained as a result of performing the processing of step 45. As described above, in the present embodiment, the vector directions are expressed in eight directions. In addition, the vector direction is represented by 0 to 7 direction codes indicating the direction shown in FIG. Specifically, the vector direction can be calculated from the coordinate values of adjacent detection points as follows. Here, the coordinate value of the detection point detected first is (x1, y1), and the coordinate value of the detection point detected later is (x2, y2). Further, it is assumed that Rx = x2-x1 and Ry = y2-y1.
If Ry <0, | Ry |> 2 | Rx |, the direction code is 0 (upward)
If Rx> 0, Ry <0,2 | Rx |> = | Ry |> = | Rx | / 2, the direction code is 1 (upward right)
If Rx> 0, | Rx |> 2 | Ry |, the direction code is 2 (rightward)
If Rx> 0, Ry> 0,2 | Rx |> = | Ry |> = | Rx | / 2, the direction code is 3 (downward to the right)
If Ry> 0, | Ry |> 2 | Rx |, the direction code is 4 (downward)
If Rx <0, Ry> 0,2 | Rx |> = | Ry |> = | Rx | / 2, the direction code is 5 (downward to the left)
If Rx <0, | Rx |> 2 | Ry |, the direction code is 6 (leftward)
If Rx <0, Ry <0,2 | Rx |> = | Ry |> = | Rx | / 2, the direction code is 7 (upward to the left)
As described above, vector data can be expressed in eight different directions. This simplifies the shape of the input trajectory and facilitates the process of specifying the shape of the input trajectory (step 64 described later). It is assumed that the upper left corner of the display screen is the origin, and the coordinates increase from the origin toward the side of the display screen.

  Returning to the description of FIG. 14, the process of step 62 is performed after step 61. In step 62, input trajectory data 22c is created based on the vector data list 22b. Specifically, the input trajectory data 22c is created by combining vector data having the same direction in the vector data stored in the vector data list 22b into one vector data. The vector data in which the same direction is continuous is, for example, four vector data having data numbers 1 to 4 in FIG. Since these four vector data have the same direction code, they are combined into one vector data. The distance of the collected vector data is the sum of the distances of the four vector data. The direction of the combined vector data is the same as that of the four vector data. As for the vector data whose data number is 5 or later, the input locus data 22c shown in FIG. 18 is obtained by collecting the vector data in the same manner as described above. In FIG. 18, the vector data (distance: 10, direction: 5) with the data number 1 is a collection of vector data with the data numbers 1 to 4 stored in the vector data list 22b shown in FIG. .

  Following step 62, in step 63, the reference graphic database 22d of the WRAM 22 is read. FIG. 19 is a diagram illustrating an example of the reference graphic database 22d. As shown in FIG. 19, in the reference graphic database 22d, the shape of the reference graphic is associated with the reference graphic data indicating the shape. Note that the reference graphic data indicating the shape of the reference graphic is composed of vector data, similar to the vector data list 22b and the input trajectory data 22c. In FIG. 19, reference graphic data indicating a square, a circle, and a triangle is shown as an example. In the present embodiment, since there are eight directions that can be expressed by vector data, the reference graphic data indicating a circle actually indicates an octagon. In this embodiment, the length of each side of the reference graphic is all 1.

In step 64, reference graphic data indicating a shape closest to the input trajectory data created in step 62 is selected from the reference graphic data read in step 63. The shape of the reference graphic data selected in step 64 is specified as the shape of the input trajectory. Specifically, the process of step 64 is performed as follows.

  In step 64, first, similarity transformation is performed on the input trajectory data. The similarity conversion is a process of converting the figure indicated by the input trajectory data into a size substantially the same as the size of the reference figure by enlarging or reducing the figure. In the present embodiment, the magnification for enlarging or reducing the vector data (referred to as vector data A) having the minimum internal distance of the vector data of the reference graphic data and the internal distance of the vector data included in the input trajectory data is the minimum Is determined based on vector data (referred to as vector data B). Specifically, it is calculated as (magnification for enlarging or reducing) = (distance of vector data A) / (distance of vector data B). For example, in order to compare with the reference graphic data shown in FIG. 19, consider the case where similarity transformation is performed on the input trajectory data shown in FIG. At this time, the minimum value of the distance of the vector data of the reference graphic data is 1, and the minimum value of the distance of the vector data included in the input trajectory data is 10. Therefore, the magnification for performing the enlargement is calculated as 1/10 (times). That is, by multiplying the vector data of the input data by 1/10, the graphic indicated by the input trajectory data can be converted to a size substantially the same as the size of the reference graphic.

After the similarity conversion process, the input trajectory data after the similarity conversion is compared with the reference graphic data. Here, a method using difference values will be described as a specific example of comparison. The difference value is a numerical value indicating the degree of difference between the shape of the input trajectory data after the similarity conversion and the shape of the reference graphic data, and is calculated by the following equation, for example.
(Difference value) = (difference in the number of vector data) × 10 + (number of differences in direction) × 2 + (total distance difference) × 1
Here, the difference in the number of vector data is the difference between the number of vector data included in the input trajectory data and the number of vector data included in the reference graphic data. For example, the number of vector data included in the input trajectory data illustrated in FIG. 18 is 3, and the number of vector data included in the reference graphic data A (rectangle) illustrated in FIG. Therefore, in this case, the difference in the number of vector data is 1.

  The direction difference number is a number in which the direction of the vector data included in the input trajectory data is different from the direction of the vector data included in the reference graphic data. For example, when the input trajectory data shown in FIG. 18 is compared with the reference graphic data A (rectangle) shown in FIG. 19, the vector data facing the right direction (vector data of data number 2 shown in FIG. 18 and the reference shown in FIG. 19). Only order 2 vector data) has the same direction. Since the vector data which is the same as the direction of the other two vector data included in the input trajectory data is not included in the vector data of the reference graphic data A shown in FIG.

  The total distance difference is the total difference between the distance of the vector data included in the input trajectory data and the distance of the vector data included in the reference graphic data. Here, the difference between two vector data having the same data number is calculated for the vector data included in the input trajectory data 22c and the vector data included in the reference graphic data. Further, the sum of differences calculated for all data numbers is calculated. For example, when comparing the input trajectory data shown in FIG. 18 (after similarity transformation) and the reference graphic data A (rectangle) shown in FIG. The sum of the differences is zero.

  In step 64, all reference graphic data are compared with the input trajectory data. As a result, the reference graphic data having the smallest difference value is selected as the shape closest to the input trajectory data. Note that when the input trajectory data shown in FIG. 18 is compared with the reference graphic data A to C shown in FIG. 19, the reference graphic data C (triangle) has a difference value of 0, which is closest to the input trajectory data. Reference graphic data C (triangle) is selected as reference graphic data. Thereby, the shape of the input locus is specified as a triangle.

  Following step 64, in step 65, an attack pattern corresponding to the shape of the input trajectory is determined based on the selected reference graphic data and the attack determination table. FIG. 20 is a diagram illustrating an example of the attack determination table. As shown in FIG. 20, in the attack determination table, the shape of the input trajectory and the attack pattern are associated with each other. In step 65, the attack pattern corresponding to the shape of the input trajectory is determined as an attack pattern corresponding to the shape of the input trajectory specified in step 64.

  Following step 65, in step 66, the size of the input trajectory is specified. Here, the size of the input trajectory is assumed to be a size based on the size of the reference graphic. That is, the size of the input trajectory is expressed by a magnification with respect to the reference graphic. For example, the shape of the input trajectory data shown in FIG. 18 is ten times as large as the shape of the reference graphic data C (triangle) shown in FIG. The magnification indicating the size of the input trajectory can be calculated as the reciprocal of the magnification when performing the above-described similarity transformation (step 64).

  Following step 66, in step 67, the attack power is determined based on the size of the input trajectory specified in step 66. The attack power is a numerical value related to the amount of damage to the enemy character. As a result of this attack power being adjusted in step 75 to be described later, the final damage of the enemy character is determined. Specifically, the value of the attack power is determined by referring to the attack determination table shown in FIG. In FIG. 20, in the attack determination table, basic damage and a magnification corresponding to the size of the input trajectory are associated with each attack pattern. The product of this basic damage and the magnification is the attack power value. For example, when the attack pattern is an attack by the magic of fire and the size of the input trajectory is three times, the attack power value is 30 (basic damage) × 0.5 = 15. After the process of step 67, the process shown in FIG.

  Returning to the description of FIG. 10, after step 45, attack processing shown in step 46 is performed. The attack process is a process for damaging an enemy character based on the attack power determined in step 45 or the like. Details of the attack process will be described below with reference to FIGS.

  FIG. 21 is a flowchart showing a detailed processing flow of step 46 shown in FIG. First, in step 71, enemy characters included in the area surrounded by the input trajectory are identified among the enemy characters included in the game image. The enemy character specified here becomes an attack target by the player character. It should be noted that enemy characters that are only partially included in the area may be attack targets or may not be attack targets. In the following step 72, it is determined whether or not there is a character specified in step 71. If there is no character identified in step 71, that is, if no enemy character is included in the area, the processing in step 73 is performed. In this case, since there is no enemy character to be attacked, in step 73, an effect display indicating that the attack is unsuccessful is performed, and the processing shown in FIG.

  On the other hand, if it is determined in step 72 that there is a character specified in step 71, processing in steps 74 to 77 is performed. The processing in steps 74 to 77 is processing for determining damage to be given to the enemy character to be attacked. First, in step 74, the attribute of the enemy character specified in step 71 is specified. The process of step 74 is performed using the enemy character state data 22f. FIG. 22 is a diagram illustrating an example of enemy character state data. As shown in FIG. 22, the enemy character state data 22f stores attribute data, HP, and MP for each enemy character. In step 74, the attribute data of the enemy character specified in step 71 is specified among the data included in the enemy character state data 22f.

  Following step 74, in step 75, damage to be given to the enemy character is determined based on the attribute data specified in step 74. In step 75, the damage is determined based on the attack power determined in step 44 and the attribute data read in step 74. In the determination process, the attack determination table shown in FIG. 20 is referred to. As shown in FIG. 20, in the attack determination table, the magnification is determined according to the attack pattern and the attribute of the enemy character. In the process of step 75, first, a magnification corresponding to the attribute of the attacking opponent is determined based on the attribute specified in step 74 and the attack pattern determined in step 65. Referring to FIG. 20 as an example, for example, when the attack pattern is an attack by water magic and the attribute of the enemy character is a flame attribute, the magnification is determined to be twice. Next, the magnitude of damage finally given to the enemy character is determined by multiplying the determined magnification by the attack power determined in step 44. In the above example, if the attack power is 15, for example, the amount of damage finally given to the enemy character is determined to be 15 × 2 = 30.

  After step 75, in step 76, an effect display corresponding to the attack pattern of the player character is displayed on the display screen (see FIG. 8). It is assumed that the image data for effect display is prepared in advance for each attack pattern. In the following step 77, the characteristic parameter (specifically, HP) of the enemy character is changed based on the magnitude of damage determined in step 75. Specifically, the CPU core 21 is updated by subtracting the HP of the enemy character state data 22f stored in the WRAM 22 by the amount of damage determined in step 75. The enemy character whose HP is updated is the enemy character included in the area surrounded by the input trajectory, that is, the enemy character specified in step 74. After step 77, the process shown in FIG.

  Returning to the description of FIG. 10 again, after step 46, the process of step 47 is performed. In step 47, it is determined whether or not the battle has ended. This determination is made based on, for example, whether the HP of the player character or the HPs of all enemy characters has become zero. That is, when the HP of the player character or the HPs of all enemy characters becomes 0, it is determined that the battle has ended, and the battle process shown in FIG. 10 ends. On the other hand, if the HP of the player character is not 0 and the HP of any one enemy character is not 0, it is determined that the battle has not ended, and the process returns to step 41. Thereafter, the processes of steps 41 to 47 are repeated until it is determined that the battle has ended. Above, description of the game process in this embodiment is complete | finished.

  As described above, according to the present embodiment, in the touch panel game device, the attack pattern can be changed according to the shape of the input trajectory drawn on the display screen by the player's input. Accordingly, various game operations can be performed, and the game can be performed with various attack patterns. In addition, since the degree of attack and the range of the attack target can be changed according to the size of the input trajectory and the range surrounded by the input trajectory, more various attacks can be made possible.

  In the above-described embodiment, an example in which the present invention is used in a battle scene in RPG has been described. However, the present invention can be used other than an attack operation on an enemy character. For example, it can be used for a recovery operation or a defense operation for the player character. Specifically, the type of recovery operation (for example, an operation for recovering HP or an operation for recovering a poisoned state) is changed according to the shape of the trajectory, and is recovered according to the size of the trajectory. It is conceivable to change the degree (for example, the amount to recover HP).

In the above embodiment, the enemy character to be attacked is an enemy character included in the area surrounded by the input trajectory. Here, the method for determining the enemy character to be attacked is not limited to the above as long as it is determined based on the area surrounded by the input trajectory. For example, only an enemy character in contact with the input trajectory may be targeted for attack, or only an enemy character outside the area may be targeted for attack (an enemy character within the area is not targeted for attack).

  In the above-described embodiment, a closed shape such as a circle, a triangle, or a quadrangle has been described as an example of the reference graphic, but the reference graphic does not have to be a closed shape. For example, an arc shape as shown in FIG. 23 or a spiral shape as shown in FIG. 24 may be used. Further, the reference graphic may have a wave shape as shown in FIG. If the reference graphic is not a closed shape, the area for determining the attack target (in the above embodiment, the area surrounded by the trajectory) cannot be determined from the shape of the reference graphic. Therefore, in this case, an area to which an attack corresponding to the reference graphic is applied may be determined in advance for the reference graphic. For example, in the case of the shape shown in FIGS. 23 to 25, the area to which the attack pattern is applied may be determined as indicated by the hatched portion in the figure.

  Furthermore, the reference graphic need not be a shape that can be drawn with a single stroke. For example, the reference graphic may have a shape in which a circle and a straight line are combined as shown in FIG. If the reference figure has a shape as shown in FIG. 26, if the locus drawn by one continuous input is processed as one input locus (see step 57 in FIG. 11), the reference figure can be drawn. It will not be possible. This is because the shape shown in FIG. 26 cannot be drawn with a single stroke. Therefore, in this case, for example, a trajectory input within a predetermined time may be processed as one input trajectory. Specifically, in step 57 in FIG. 11, it may be determined whether or not a predetermined time has elapsed since the input was detected in step 52.

  In another embodiment, the damage given to the enemy character may be changed according to the number of enemy characters included in the area surrounded by the input trajectory. For example, the damage given to the enemy character when there is one enemy character included in the area may be made larger than the damage given when there are two enemy characters.

  By the way, in each of the above-described embodiments, the case where two physically separated LCDs 11 and 12 are vertically arranged as an example of a liquid crystal display unit for two screens (in the case of two screens on the top and bottom) has been described. As shown in FIG. 27, one housing 18c may be formed in a horizontally long shape so that the LCDs 11 and 12 for two screens can be accommodated in the left and right positions except for the upper housing 18b. In that case, considering that there are many right-handed users, the LCD 12 with the touch panel 13 attached is preferably arranged on the right side and the LCD 11 is arranged on the left side. However, when making a left-handed portable game device, the arrangement is reversed.

  As another arrangement example, instead of a configuration in which two physically separated LCDs 11 and 12 are arranged vertically, as shown in FIG. 28, a vertically long image having the same horizontal width and a double vertical length. By using a single LCD 11a of a size (that is, an LCD with one physical display size and two vertical display sizes), a liquid crystal display unit for two screens is arranged in the vertical direction, thereby providing two screens. You may comprise so that a game image may be displayed up and down (namely, displayed adjacently, without the upper and lower boundary part). Further, as shown in FIG. 29, a map image for two screens in the horizontal direction is displayed on the left and right using one horizontal size LCD 11b having the same vertical width and a horizontal length of twice (ie, horizontally). You may comprise so that it may display adjacently, without the right-and-left boundary part. That is, in the examples of FIGS. 28 and 29, a plurality of game images are displayed by physically dividing one screen into two.

  The present invention can be used for the purpose of providing various ways of playing games to players by enabling various game operations.
