The touch panel display 191 also functions as an operation unit for the player to perform game operations. Specifically, when the locus shape drawn by the player on the touch panel display 191 matches the command assignment shape assigned to the command, the input of the command is recognized, and an action event specified by the command is generated. .

  The sound output unit 192 outputs the sound generated by the present embodiment, and its function can be realized by a speaker, headphones, or the like.

  The portable information storage device 194 stores player personal data, game save data, and the like. Examples of the portable information storage device 194 include a memory card and a portable game device. The communication unit 196 performs various controls for communicating with the outside (for example, a host device or another game device), and functions thereof are hardware such as various processors or communication ASICs, programs, and the like. Can be realized.

  Note that a program (data) for causing a computer to function as each unit of this embodiment is distributed from the information storage medium of the host device (server) to the information storage medium 180 (storage unit 170) via the network and communication unit 196. May be. Use of the information storage medium of such a host device (server) can also be included in the scope of the present invention.

  The processing unit 100 (processor) performs processing such as game processing, image generation processing, or sound generation processing based on operation data and programs from the operation unit 160. Here, as the game process, a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for placing an object such as a character or a map, a process for displaying an object, and a game result are calculated. There is a process or a process of ending a game when a game end condition is satisfied. The processing unit 100 performs various processes using the storage unit 170 as a work area. The functions of the processing unit 100 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs.

  The processing unit 100 includes an object space setting unit 110, a movement / motion processing unit 111, a virtual camera control unit 112, a command recognition unit 113, a counting unit 115, an event generation unit 116, a display control unit 117, a correction processing unit 118, and an image generation. Unit 120 and sound generator 130. Note that some of these may be omitted.

  The object space setting unit 110 is composed of various objects (primitive surfaces such as polygons, free-form surfaces, or subdivision surfaces) representing display objects such as characters, targets, cars, buildings, trees, columns, walls, and maps (terrain). (Object) is set in the object space. That is, the position and rotation angle (synonymous with direction and direction) of the object (model object) in the world coordinate system are determined, and the rotation angle (X, Y, Z axis around the position (X, Y, Z)) is determined. Arrange objects at (rotation angle).

  The movement / motion processing unit 111 performs a movement / motion calculation (movement / motion simulation) of an object (character, target, etc.). That is, an object (moving object) is moved in the object space or an object is moved based on operation data input by the player through the operation unit 160, a program (movement / motion algorithm), various data (motion data), or the like. Perform processing (motion, animation). Specifically, a simulation process for sequentially obtaining object movement information (position, rotation angle, speed, or acceleration) and motion information (position or rotation angle of each part object) every frame (1/60 second). I do. A frame is a unit of time for performing object movement / motion processing (simulation processing) and image generation processing.

  The virtual camera control unit 112 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, a process for controlling the position (X, Y, Z) or the rotation angle (rotation angle about the X, Y, Z axes) of the virtual camera (process for controlling the viewpoint position and the line-of-sight direction) is performed.

  For example, when an object (eg, character, ball, car) is photographed from behind using a virtual camera, the position or rotation angle of the virtual camera (the direction of the virtual camera is set so that the virtual camera follows changes in the position or rotation of the object. ) To control. In this case, the virtual camera can be controlled based on information such as the position, rotation angle, or speed of the object obtained by the movement / motion processing unit 111. Alternatively, the virtual camera may be controlled to rotate at a predetermined rotation angle or to move along a predetermined movement path. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or rotation angle of the virtual camera.

  The command recognition unit 113 performs recognition processing for commands input by the player. Here, the commands subject to recognition processing are, for example, a command that specifies an action event to be generated (type and content of action event), a command that instructs activation (start, generation) of the action, and the like. The action event is an event that causes a player character (a pseudo player in the case of the first person viewpoint) to perform a given action or action. Specifically, action events specified by recognized commands include attacking, defending, recovering, throwing, hitting, kicking, running, cutting, hitting, blowing, playing, moving, rotating, etc. There are action events.

  The player draws a locus shape on the touch panel display 191, touches an icon image displayed on the touch panel display 191, touches an arbitrary point on the touch panel display 191, operates the operation unit 160, and the sound input device. A command is input by inputting a sound (voice, clapping sound) to 162. The command recognition unit 113 performs a recognition process for the input command.

  Specifically, the command recognition unit 113 performs a matching process (shape matching process) between the locus shape (shape, figure) drawn by the player on the touch panel display 191 and the command assignment shape (shape, figure) assigned to the command. To perform command recognition processing. For example, when the trajectory shape matches a command allocation shape (a shape or template registered in advance as a sign representing the command) (matches within an allowable range), it is recognized that the command has been input by the player. This recognition process can be realized using a known character recognition process. The trajectory shape data drawn by the player is temporarily stored in the trajectory shape data storage unit 174 as time-series position data (touch position data). The command allocation shape data is stored in advance in the command allocation shape data storage unit 176 as registration data. The command recognition unit 113 performs matching processing based on the locus shape data temporarily stored in the locus shape data storage unit 174 and the command assignment shape data stored in the command assignment shape data storage unit 176.

  The command recognition unit 113 performs recognition processing of an action activation command that instructs the activation of the action specified by the command, following the recognition processing of the command specifying the action (action type and content). Specifically, in the first operation period (first operation phase), the player inputs a command designating an action, and the command recognition unit 113 performs a command recognition process. Then, in the second operation period (second operation phase), the player inputs an action activation command for the command, and the command recognition unit 113 performs recognition processing for the action activation command. The player inputs a given trajectory shape on the touch panel display 191, touches an icon image or an arbitrary point displayed on the touch panel display 191, operates the operation unit, or uses the sound input device 162. An action trigger command can be input by inputting sound. Then, the command recognition unit 113 performs recognition processing of the action activation command input in this way. For example, when the trajectory shape drawn on the touch panel display 191 is a line segment shape in the direction from the touch panel display 191 to the display 190 or includes such a line segment shape, the command recognition unit 113 performs an attack action. Recognize that the activation command is input. In addition, when the trajectory shape drawn on the touch panel display 191 is a line shape in the direction from the display 190 to the touch panel display 191 or includes such a line shape, a command for invoking a defensive action or a recovery action It is recognized that has been entered. Here, the direction from the touch panel display 191 to the display 190 is, for example, a line segment shape when the vertical direction (height direction) of the touch panel display 191 is the Y-axis direction and the horizontal direction is the X-axis direction. This is a direction in which the Y-axis coordinate component of the direction vector becomes positive. The direction from the display 190 to the touch panel display 191 is a direction in which the Y-axis coordinate component of the direction vector of the line segment shape becomes negative.

  In addition, the command recognition unit 113 performs a matching process between each locus shape of a plurality of locus shapes drawn by the player on the touch panel display 191 and each command assignment shape assigned to the plurality of commands, thereby recognizing the plurality of commands. Process. Here, the plurality of trajectory shapes are trajectory shapes drawn by the player for the purpose of inputting a combo command that is a given command combination, and the plurality of commands are a series of commands constituting the command combination. It is a command.

  The similarity calculation unit 114 included in the command recognition unit 113 performs a process of calculating the similarity between the locus shape drawn on the touch panel display 191 and the command assignment shape. This similarity calculation process can be realized by a similarity calculation process in known character recognition. Specifically, the similarity calculation unit 114 converts the direction vector (for example, the direction vector connecting the vertices and the direction vector of the stroke) constituting the locus shape drawn by the player and the reference direction vector constituting the command assignment shape. Based on this, the similarity is calculated. For example, the difference between the direction (angle) of the direction vector of the trajectory shape and the direction (angle) of the reference direction vector of the command assigned shape is obtained, and the similarity is calculated. That is, the degree of similarity is calculated so that the degree of similarity increases as the difference between these directions (angle difference) decreases. Alternatively, the degree of similarity may be calculated by obtaining the difference between the length of the direction vector of the trajectory shape and the length of the reference direction vector of the command assignment shape. That is, the similarity is calculated such that the smaller the difference between the lengths, the higher the similarity. Note that the similarity may be calculated based only on the direction difference, or the similarity may be calculated based on the direction difference and the length difference. Alternatively, the similarity may be calculated based on an element different from the difference in direction and the difference in length. For example, when the command allocation shape is a one-stroke drawing shape, the similarity may be calculated so that the degree of similarity is increased when the player draws a trajectory shape appropriately drawn with one stroke. Alternatively, the degree of similarity may be calculated so that the degree of similarity becomes higher as the stroke order, the number of strokes, or the drawn direction is more accurate, as well as the shape of the locus itself.

  The counting unit 115 performs processing for counting the time limit for command input. This counting process can be realized, for example, by decrementing (or incrementing) a count value (a count value indicating a time limit) for each frame update. Note that the time limit counted by the counting unit 116 may be a time limit for input of a command designating an action (time limit for the first operation period), or a time limit for input of an action trigger command (second time). The time limit of the operation period).

  The event generation unit 116 generates an action event (an action event corresponding to the command) specified by the command recognized by the command recognition unit 113. Specifically, the action event flag of the command is turned on to notify the display control unit 117 and the like that the action event has occurred. An event is a meaning of an event generally used in programming.

  When the time limit for command input is counted by the counting unit 115, the event generation unit 116 is designated by the recognized command on the condition that the command is recognized by the command recognition unit 113 within the time limit. An action event is generated. When the player inputs an action trigger command, an action event specified by the command is generated on the condition that the action trigger command is recognized by the command recognition unit 113. Note that an action event specified by the command may be generated on the condition that it is recognized that the command is input within the time limit and the action activation command is recognized.

  In addition, when the player inputs a plurality of commands while drawing a plurality of trajectory shapes, the event generation unit 116 receives a combination of a plurality of recognized commands (a plurality of commands recognized within the time limit). If the combination matches (combo command), an action event specified by the combination of the plurality of commands is generated.

  The display control unit 117 performs control for displaying an image of the generated action event on the display 190 when the action event occurs. For example, when an attack action event occurs, the display control unit 117 performs control to display on the display 190 an image of a scene in which the player character attacks the target object (such as an enemy character). Specifically, an image of a scene where the player character activates an attack such as a shot, an image of a scene where the attack flies in the direction of the target object, an image of a scene where the attack hits the target object, etc. It is displayed on the display 190. When a defense action event occurs, the display control unit 117 performs control to display an image of a scene where the player character defends against an attack from an enemy on the display 190. Specifically, the display 190 displays an image of a scene in which the player character casts a defense magic or generates a barrier, an image of a scene in which an attack from an enemy rebounds or is weakened by the defense magic or the barrier, and the like. Further, when a recovery action event occurs, the display control unit 117 performs control to display an image of a scene in which the player character recovers a status such as the physical strength of the player character or himself / herself on the display 190. Specifically, an image of a scene where the player character casts magic for recovering himself or his fellow characters, an image of a scene using recovery medicine, or an image of a scene showing how the player character or his fellow characters recover Etc. are displayed on the display 190.

  The correction processing unit 118 performs correction processing for the attack direction and the like. For example, it is assumed that a trajectory shape of a line segment shape is drawn on the touch panel display 191, and an attack action event is generated in which the attack direction is set based on the direction of the line segment shape. In this case, the correction processing unit 118 performs correction processing for causing the target object displayed on the display 190 to hit an attack whose direction is set by the direction of the line segment shape. Specifically, when the target object is not located on the extension line of the attack direction set by the direction of the line segment shape, the attack direction is corrected so that the attack hits the target object. For example, correction processing is performed such that an attack bullet (magic bullet) tracks the target object, such as a homing missile. Also, the attack direction on the XZ plane (Z axis is the depth direction axis, and the X axis is orthogonal to the Z axis) is set according to the direction of the line segment shape, and the attack Y axis (perpendicular to the X and Z axes) The (axis in the height direction) component is obtained by automatic correction processing so that the attack hits the target object.

  The image generation unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting it to the display 190 (or touch panel display 191). In the case of generating a so-called three-dimensional game image, first, geometric processing such as coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, or perspective transformation is performed, and drawing data ( The position coordinates, texture coordinates, color data, normal vector, α value, etc.) of the vertexes of the primitive surface are created. Based on the drawing data (primitive surface data), the object (one or a plurality of primitive surfaces) after perspective transformation (after geometry processing) is stored as image data in units of pixels such as a drawing buffer 172 (frame buffer, intermediate buffer, etc.) Can be drawn in a VRAM). Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. Note that the image generated according to the present embodiment and displayed on the display 190 may be a three-dimensional image or a two-dimensional image.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  Note that the game device of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play. Further, when a plurality of players play, game images and game sounds to be provided to the plurality of players may be generated using one terminal, or connected via a network (transmission line, communication line) or the like. Alternatively, it may be generated by distributed processing using a plurality of terminals (game machine, mobile phone).

2. Next, the method of this embodiment will be described with reference to the drawings. In the following, the case where the present invention is applied to a magic shooting game in which magic is applied to enemies that appear one after another and an attack is applied, or a role playing game will be described. Not limited to games.

2.1 Command Input by Touch Panel Display In the game realized by the present embodiment, the game progresses by drawing the shape of the magic command on the touch panel display, shooting with the drawn magic command, and defeating the enemy. For example, when the player draws a locus shape as shown in FIG. 3A on the touch panel display 191 with a finger or a pen, and this locus shape matches (matches) the command assignment shape assigned to a specific magic command, the magic command The input is recognized. Specifically, an image of a magic bullet appears in front of the player character PCH on the display 190 and displays that magic has been accepted. At this time, for example, a sound may be notified that magic has been determined. Then, the magic attack action occurs, and as shown in FIG. 3 (B), an image showing that the magic bullet fired by the player character PCH is hitting the target object TOB is displayed on the display 190.

  In the present embodiment, the touch panel display 191 functions as an operation unit for the player to input commands, and also displays a status screen or game for informing the player of the status of parameters such as attack power, defense power, physical strength, and possessed items. It also functions as a display for displaying the map screen. 3B is a third person screen on which the player character PCH is displayed, it may be a first person screen on which the player character PCH is not displayed. In this case, the term “player character” in this embodiment can be replaced with the term “player” or “pseudo player”. Further, the locus shape drawn on the touch panel display 191 is not actually displayed on the touch panel 191, but may be displayed. Further, a frame for drawing such a trajectory shape may be displayed on the touch panel display 191. If such a frame is displayed, the success rate of the command recognition process can be increased.

  4A and 4B show other examples of command assignment shapes. For example, FIG. 4A shows an example of a command assignment shape assigned to the defense command. When the trajectory shape drawn by the player matches the command assignment shape shown in FIG. 4A (matches within the allowable range), a defense action event occurs. In other words, an action event occurs in which the player character defends against an attack from the enemy, and an image showing the action event is displayed on the display 190.

  FIG. 4B shows an example of a command assignment shape assigned to the recovery command. When the trajectory shape drawn by the player matches the command assignment shape shown in FIG. 4B, a recovery action event occurs. That is, an action event occurs in which the player character recovers the status of himself or his fellow character, and an image showing the action event is displayed on the display 190.

  FIG. 5A shows a command assignment shape assigned to each command of a plurality of commands which are combo commands. In the present embodiment, a matching process is performed between each trajectory shape of a plurality of trajectory shapes drawn by the player and each command assignment shape shown in FIG. 5A to perform a command recognition process. For example, in FIG. 5A, it is determined whether or not a series of trajectory shapes drawn by the player matches a triangular shape, a quadrangular shape, or a rhombus shape. Then, when the recognized combination of a plurality of commands matches a given combination (combo), an action event specified by the combination of the plurality of commands is generated. That is, as shown in FIG. 5B, an image of an action event in which the player character PCH makes a combo attack on the target object TOB is displayed on the display 190. Whether or not a command combination matches a given combination may be determined including or not including whether or not the command input order matches.

  As described above, in this embodiment, a command corresponding to the locus shape drawn by the player on the touch panel display 191 is recognized, and an action image of the command is displayed on the display 190. Therefore, advanced operation input that cannot be realized by the levers and buttons of the operation unit can be performed, the game operation interface environment of the player can be improved, and an unprecedented game operation interface environment with high playability can be provided.

2.2 Time Limit In FIG. 6, a time limit is set for a command (trajectory shape) input using the touch panel display 191. That is, the time limit for command input is counted by the counting process. When the time limit count starts, a time gauge indicating the remaining time limit is displayed as shown in FIG. As the remaining time of the time limit decreases, the gauge amount of the time gauge decreases. The player is required to draw a locus shape as shown in FIG. 6 on the touch panel display 191 within the time limit. Then, a trajectory shape is drawn within the time limit, and when this trajectory shape matches the command assignment shape, an action event for that command occurs. For example, if it can only be drawn halfway within the time limit, the action event for that command does not occur. For example, in a command assignment shape that requires a single stroke, when a stroke is not completed, an action event for that command does not occur. Even if a trace shape is drawn within the time limit, even if the trace shape does not match the command allocation shape within an allowable range, an action event for the command does not occur.

  For example, if the time limit is not set and there is sufficient time, it is easy for the player to draw the trajectory shape to match the command assignment shape. However, if the time limit is not set, the game will not feel tense and the game will not be interesting.

  On the other hand, since the time limit is set in FIG. 6, the player is required to accurately and quickly draw the locus shape matched with the command assignment shape. Therefore, it becomes possible to give the player a sense of urgency and tension, and the fun of the game can be greatly improved.

  In FIG. 6, the remaining time of the time limit is notified to the player using a time gauge, but the player may be notified using an image other than the time gauge (for example, an hourglass image). Further, the remaining time of the time limit may be notified to the player by sound instead of an image. For example, as the remaining time decreases, the tempo of the game sound (BGM, sound effect) may be increased, the volume of the game sound may be increased, or the tone of the game sound may be increased.

2.3 Action Invocation Command An action event may be generated on the condition that an input of an action invocation command that activates the action event is recognized.

  For example, after a trajectory shape as illustrated in FIG. 3A is drawn and a command for designating an attack is input, a line segment shape as illustrated in FIG. Recognizes that an activation command has been entered. Then, as shown in FIG. 8, an attack action event is generated in which the attack direction is set based on the direction of the line segment shape. That is, a magic bullet is blown in the direction of the line segment shape to hit the target object TOB.

  7B, the locus shape drawn on the touch panel display 191 is a line segment shape in a direction from the display 190 to the touch panel display 191 (a direction in which the Y coordinate component is negative, a direction toward the player side). Included (the last line segment shape is a line segment shape as shown in A1). In this case, it is recognized that a command for issuing a defense action or a recovery action has been input. Then, an image that rebounds an enemy attack by generating a barrier in front of the player character PCH and an event image in which the player character PCH performs a recovery operation are displayed on the display 190.

  Thus, by setting the attack direction according to the direction of the line segment shape, an intuitive and easy-to-understand game operation interface environment can be provided to the player.

  In addition, when the locus shape drawn on the touch panel display 191 is a line segment shape in the direction from the touch panel display 191 to the display 190 (a direction in which the Y coordinate component becomes positive) (or includes such a line segment shape). ), It may be recognized that an attack action activation command has been input.

  Further, when an attack action is activated by drawing a line segment shape as shown in FIG. 7A, it is desirable to correct the attack direction by a correction process. For example, the attack direction in the XZ plane is set by drawing a line segment shape as shown in FIG. 7A, the height (Y-axis component) is automatically corrected, and the attack hits the target object TOB. Like that. Alternatively, an attack bullet may be tracked and hit by the target object TOB like a homing missile.

  Further, the power and speed of the attack may be changed based on the length of the direction vector of the line segment shape. For example, as the length of the direction vector of the line segment shape is longer, the attack power may be increased, or the attack speed (bullet speed) may be increased.

  Further, for example, when a command is input as shown in FIG. 3A and a line segment shape as shown in FIG. 7A is drawn a plurality of times, an attack (or defense, recovery) action is performed a plurality of times. May be. That is, let the continuous bullets fly. In this case, the number of times of occurrence of the attack action (number of possible occurrences) may be controlled based on the similarity (accuracy of matching) between the trajectory shape and the command assignment shape. For example, the higher the similarity is, the more attack actions can be activated. In this way, the player can be given effective motivation to draw accurately so that the degree of similarity is high.

  Further, the number of occurrences of attack actions (number of possible occurrences) may be controlled in accordance with status parameters such as player experience value parameters. For example, as the player's experience value parameter increases, the number of occurrences of attack actions (number of possible occurrences) is increased.

  Further, when the command input (command recognition) in FIG. 3A fails, a weak normal attack may be performed when the action activation command is input.

  Also, when setting the time limit as shown in FIG. 6, an action event may be generated on the condition that the command is input within the time limit even if the input of the action activation command is not recognized. Good. Alternatively, an action event may be generated on the condition that the command is recognized within the time limit and the action activation command is input.

  The locus shape for inputting the action activation command is not limited to the line segment shape as shown in FIG. 7A, and may be a complex locus shape having two or more line segments. Moreover, you may make it change the way of starting action according to the kind of locus | trajectory shape. For example, the power of attack, the direction of attack, the number of attacks, etc. may be changed according to the type of trajectory shape.

3. Processing of this embodiment Next, a detailed processing example of this embodiment will be described using a flowchart. FIG. 9 is a flowchart of processing when an action event is generated on the condition that a command is recognized within the time limit.

  First, counting of the time limit count value is started (step S1). And the acquisition process of the locus | trajectory shape drawn on the touchscreen display is performed (step S2).

  Next, matching processing and similarity calculation processing between the acquired trajectory shape and a command assignment shape registered in advance are performed (step S3). Then, it is determined whether or not the command is recognized within the time limit set by the time limit count value (step S4). If not recognized, the process proceeds to step S7. On the other hand, if it is recognized, an action event of the recognized command is generated (step S5). The action event image is displayed on the display (step S6), and the time limit count value is reset (step S7).

  FIG. 10 is a flowchart of processing when an action event is generated on condition that an action trigger command is recognized.

  First, a process for acquiring a trajectory shape drawn on the touch panel display is performed (step S11). Then, matching processing of the acquired trajectory shape and command assignment shape, and similarity calculation processing are performed (step S12). Subsequently, an action activation command recognition process is performed (step S13).

  Next, it is determined whether or not an action activation command has been recognized (step S14). If it is recognized, an action event of the recognized command is generated (step S15). Then, an image of the action event is displayed on the display (step S16).

  FIG. 11 is a flowchart of processing when an action event is generated on the condition that a command is recognized within a time limit and an action activation command is recognized.

  First, the count of the time limit count value is started (step S21), and the trajectory shape drawn on the touch panel display is acquired (step S22). Then, matching processing between the trajectory shape and the command allocation shape and similarity calculation processing are performed (step S23). Subsequently, action activation command recognition processing is performed (step S24).

  Next, it is determined whether or not the command is recognized within the time limit (step S25). If the command is recognized within the time limit, it is determined whether or not the action activation command is recognized (step S26). If an action trigger command is recognized, an action event of the command recognized in step S25 is generated (step S27). Then, the action event image is displayed on the display (step S28), and the time limit count value is reset (step S29).

  FIG. 12A is a flowchart illustrating an example of a trajectory shape acquisition process (step S2 in FIG. 9, step S11 in FIG. 10, and step S22 in FIG. 11) drawn on the touch panel display.

  First, it is determined whether or not it is a frame update timing (step S31). If it is the frame update timing, the coordinates of the touch position of the touch panel display are acquired (step S32). That is, the coordinates of the touch position are received from the touch panel display. Then, the acquired touch position coordinates are stored as locus shape data in association with the frame number (step S33).

  FIG. 12B is an example of trajectory shape data (frame number, touch position coordinates) acquired by the processing of FIG. Thus, the trajectory shape data is temporarily stored in the storage unit as time-series position data.

  FIGS. 13 and 14 are flowcharts showing an example of the matching process between the locus shape and the command assignment shape, and the similarity calculation process (step S3 in FIG. 9, step S12 in FIG. 10, and step S23 in FIG. 11).

  First, the touch position coordinates (Xn-1, Yn-1) in the previous frame and the movement direction vector (DXn-1, DYn-1) in the previous frame are read (step S41). Then, as shown in FIG. 15A, the movement in the current frame is based on the touch position coordinates (Xn, Yn) in the current frame and the touch position (Xn-1, Yn-1) in the previous frame. A direction vector (DXn, DYn) is obtained (step S42). Specifically, DXn = Xn-Xn-1 and DYn = Yn-Yn-1 are obtained.

  Next, based on the movement direction vector (DXn, DYn) in the current frame obtained in step S42 and the movement direction vector (DXn-1, DYn-1) in the previous frame read in step S41. Then, the vertex position detection process is performed (step S43). Then, it is determined whether or not the vertex position is detected (step S44). If detected, the detected vertex position is stored in the storage unit (step S45). Next, it is determined whether or not the finger (pen) has been released (step S46). If not, the process returns to step S41.

  The vertex position detection process in step S43 can be realized by obtaining an angle (inner product) formed by the movement direction vector (DXn, DYn) and the movement direction vector (DXn-1, DYn-1). Specifically, when the angle formed by these vectors is equal to or smaller than a predetermined angle (for example, 135 degrees, 90 degrees, etc.), the corresponding touch position is determined to be a vertex.

  Next, as shown in FIG. 14, the vertex positions detected and stored in steps S44 and S45 of FIG. 13 are read (step S51). For example, in FIG. 15B, vertex positions (VX0, VY0), (VX1, VY1), (VX2, VY2), (VX3, VY3) are read. Then, a direction vector connecting these vertex positions is obtained (step S52). For example, in FIG. 15B, DV0, DV1, DV2, and DV3 are obtained.

  Next, matching processing and similarity calculation processing between the obtained direction vector and the reference direction vector constituting the command allocation shape are performed (step S53). Specifically, the difference (angle difference) between the direction (angle) of the direction vector and the direction (angle) of the reference direction vector, or the difference between the length of the direction vector and the length of the reference direction vector, Calculate the similarity. FIG. 15C shows an example of the reference direction vector. In FIG. 15C, for example, matching processing and similarity calculation processing are performed based on a reference direction vector quantized into 16 divisions.

  Next, it is determined whether or not all the direction vectors and the reference direction vector are matched within the allowable range (step S54). If matching is performed, the matching flag is set to ON (step S55). Sets the matching flag to OFF (step S56). By using this matching flag, it can be determined whether or not an action corresponding to the command is generated.

  When the matching flag is set to ON, the parameter value of the attack power (defense power, recovery power) and the number of attack actions (defense action, recovery action) are calculated based on the similarity calculated in step S53. Set (step S57). For example, the higher the similarity is, the higher the parameter value of the attack power (defense power, recovery power) is set. Or it sets so that the frequency | count of attack action (defense action, recovery action) may increase, so that similarity is high. As a result, the player can advantageously advance the game.

  FIG. 16 is a flowchart illustrating an example of attack direction correction processing.

  First, a process for acquiring a trajectory shape drawn on the touch panel display is performed. (Step S61). Then, it is determined whether or not the trajectory shape is a line segment shape in a direction from the touch panel display to the display (step S62, see FIG. 7A). If the line segment shape is in such a direction, the attack action trigger flag is set to ON (step S63). If the line segment shape is not in such a direction, the attack action trigger flag is set to OFF. (Step S64).

  Next, when the attack action activation flag is set to ON, the direction vector of the line segment shape is set to the initial velocity vector of the bullet (attack in a broad sense) (step S65). For example, in FIG. 17, the direction vector of the line segment shape is set to the initial velocity vector VC0 of the bullet.

  Next, based on the position of the bullet in the previous frame and the velocity vector, the position of the bullet in the current frame is obtained (step S66). For example, in FIG. 17, the bullet position (X1, Y1) in the current frame is obtained based on the bullet position (X0, Y0) in the previous frame and the velocity vector VC0.

  Next, it is determined whether or not the target object exists on the extension line of the velocity vector (step S67). If it does not exist, speed vector (attack direction) correction processing is performed (step S68). For example, in FIG. 17, since the target object TOB does not exist on the extension line EL of the velocity vector VC0, the correction process is performed so that the direction of the velocity vector is more directed to the direction of the target object TOB. Then, it is determined whether or not a bullet hits the target object (step S69), and if not hit, the process returns to step S66.
