Description

This invention relates to a program you and game system for executing a game of action games in which the player character by the player's operation to fight non-player character by making full use of the attack technique.

  In recent years, a game machine (for example, Wii (registered trademark)) having a function of detecting a swing operation of a controller by a player has become widespread, and an attack technique can be performed by swinging operation instead of button operation using this game machine. A bodily sensation action game has been put to practical use. In the sensation action game, for example, a player can actually slash an enemy character in the game screen with a weapon such as a sword by swinging a controller. The player can defeat the enemy character by intuitive operation of the remote controller, and can experience a realistic game as if he was actually fighting.

  In such action games, there are games that can cause different actions (such as slashing to the right if swinging to the right, and then cutting to the left if swinging to the left) depending on the intuitive way of swinging the controller by the player (for example, , Patent Document 1, Non-Patent Document 1)

  Further, in the bodily sensation action game described in Patent Document 1, by switching the operation mode by pressing the operation button, another attack technique is provided even if the controller swings the same way. Specifically, if the controller is shaken in a predetermined manner while pressing the operation button, the A attack is performed, and if the same manner is performed without pressing the operation button, the B attack is issued.

  However, in the games of Patent Document 1 and Non-Patent Document 1, the player's swing operation is sensed by an acceleration sensor built in the controller, and the detection accuracy is not so high, so the player does not swing just by moving the controller. However, it is determined that the player has swung in a direction different from the direction in which the player has swung, and an action different from the desired action is easily recognized.

  Further, in the game of Patent Document 1, even if the controller is shaken in the same manner by turning on / off the operation button, different attack techniques can be delivered, but in the end, only two types of ON / OFF switching are performed. Therefore, in order for a player to launch various attack techniques, the player must be required to shake the controller in various ways, and if a variety of attack techniques is pursued, more malfunctions will occur. It was easy to occur.

  Furthermore, in a game in which an attack technique is played by shaking the controller, the player inevitably increases the number of times the player shakes the controller. Therefore, when the game is played for a long time, the player becomes tired.

Therefore, the present invention allows a player to perform various attack operations intuitively without malfunction, and allows a player to perform attack operations without feeling tired even when playing a game for a long time. and to provide a game system which executes a game program Oyo Biko programs possible.

According to a first aspect of the present invention, there is provided a computer of a game system including a controller having an operation element that receives a player's operation, a posture acquisition unit that acquires a posture of the controller, a character is generated in a game space, and the controller character control means for controlling the activity of the character in accordance with the operation, to function as the character control means, when the operating element is operated, based on the posture of the controller obtained by the posture acquisition section, wherein The character is caused to perform an attacking action from a direction in which the upper surface of the controller is facing.

The invention of claim 2 is a game system comprising a controller having an operation element for accepting a player's operation, a storage unit storing the game program according to claim 1, and a computer executing the game program. is there.

  According to the present invention, by changing the posture (orientation) of the controller, even when an operation is performed on the same operator, a plurality of types of attack techniques can be used properly. You can give out tricks. In addition, by relating the attack technique to the direction (posture) of the controller, the player can intuitively perform the attack operation.

  Further, the detection of the attitude of the controller is more accurate than the detection of the swinging operation, and since the attack technique is finally determined by a digital operation such as an operation of the operation element, malfunction is unlikely to occur.

  In addition, since the player's operation is only the change of the controller's posture and the operation of the operator, the player feels tired when the operation is performed for a long time as compared with the case where the swing operation is performed. It becomes difficult.

  Further, since only the attitude of the controller is changed, the operation can be performed in a space-saving manner as compared with the case where the swing operation is performed. This is particularly effective in the case of a game in which a plurality of players can participate.

The stick 78a is an operation unit that outputs an operation signal according to the tilting direction by tilting the tiltable stick protruding from the upper surface of the housing 77. For example, the player can specify an arbitrary direction and position by tilting the tip of the stick in an arbitrary direction of 360 °, and can indicate a moving direction of a player character or the like appearing in the virtual game world, or move a cursor. You can indicate the direction.

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

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

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

  Since the housing 71 of the subunit 76 is connected to the subunit 76 by a connection cable 79 that can be bent, the imaging direction of the imaging information calculation unit 74 changes even if the direction or position of the subunit 76 is changed. do not do. The subunit 76 may be provided with an imaging information calculation unit similar to that of the core unit 70.

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

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

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

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

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

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

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

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

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

  Here, an action game executed in the game system having the above-described configuration will be described. In this game, a player character operated by a player accomplishes a mission by subjugating an enemy character. Player characters can use various weapons such as “large sword (big sword used with both hands)”, “one-handed sword (small sword used with one hand)”, “hammer”, etc. Use it to defeat enemy characters by damaging them. The player operates the player character using the controller 7, but the player character can play out a plurality of types of attack techniques with one weapon by the player's operation. The player's operation method and attack technique will be described later with reference to FIG.

  A game system as shown in FIG. 6 can be functionally realized by causing the game device described above to read a game program for executing such a game. The game system includes an operation detection unit 50 (corresponding to the posture acquisition unit and swing acquisition unit of the present invention), a game progress control unit 51, a drawing processing unit 55, and the like. The game progress control section 51 includes a player character control section 52 (corresponding to the character control means and continuous attack means of the present invention), a non-player character control section 53, and a game space control section 54.

  The operation detection unit 50 includes a data processing unit such as the CPU 30 and the GPU 32 and the controller 7, detects (acquires) various operations of the player, and transmits them to the game progress control unit 51. The game progress control unit 51 includes a data processing unit such as the CPU 30 and the GPU 32, generates a virtual game space and characters, and changes the above-described game space according to the player's operation and the passage of time. The game is advanced by performing processing such as activating the character.

  The player character control unit 52 generates a player character in the game space, and controls activities such as use of weapons (attack by an attack technique, guard, etc.) based on operation information input from the operation detection unit 50. The non-player character control unit 53 generates a non-player character in the game space and controls the activity of the non-player character. The game space control unit 54 generates a game space for the field selected based on the operation information input from the operation detection unit 50, and controls the environment such as weather and day / night changes in the game space.

  The drawing processing unit 55 includes a data processing unit such as the CPU 30 and the GPU 32, generates a 3D game space generated by the game progress control unit 51 and a game image in which a character is projected on a 2D screen, and outputs the game image to the monitor 2. . In addition, the drawing processing unit 55 generates an image of a virtual camera obtained by photographing the game space horizontally from behind the player character as the initial game image, and this image is displayed on the monitor 2. Furthermore, the drawing processing unit 55 controls the position and direction of the virtual camera according to the operation of the cross key 72a of the core unit 70 by the player.

  Hereinafter, a camera position control method using the cross key 72a will be described. The virtual camera rotates around a gazing point that is virtually set in the game space. The player can instruct the rotation angle of the virtual camera to an arbitrary 360 ° left and right by operating the left and right controls of the cross key 72a, and by operating the up and down (front and back) controls of the cross key 72a. The rotation angle of the virtual camera can be instructed to a predetermined predetermined angle in five stages up and down. The five steps are horizontal, upward two steps, and downward two steps. Thereby, the game image in the direction desired by the player can be displayed on the monitor 2. Note that the player can reset the camera direction to the initial direction for shooting the game space horizontally from behind the player character by pressing the C button 78d on the lower surface of the subunit 76.

  Further, the player can instruct the moving direction of the player character by tilting the control stick 78a of the subunit 76 in an arbitrary direction. The player moves the player character toward the gazing point of the virtual camera (in the back of the game screen) by tilting the control stick 78a upward (forward). Conversely, the player moves the player character away from the point of gazing (before the game screen) by tilting the control stick 78a downward (backward). In other words, the movement direction of the player character with the gazing point direction as the front is determined by the operation of the virtual camera, and the player character moves on the ground according to the tilt direction of the control stick 78a with the gazing point direction as the front. Thereby, the player can move the player character intuitively toward the point shown on the monitor 2 at that time, and can move the player character to any place in the game space as desired.

  The player character can own multiple types of weapons. When the player selects one type of weapon from among the weapons possessed by the player character and directs the player character to the battle game field, the player character performs an attack technique using the selected weapon in the game field. Can be extended. A plurality of attack techniques using each weapon are set for each weapon, and the player can select the attack technique by operating the controller.

  Hereinafter, with reference to FIG. 7, an operation method for delivering a plurality of attack techniques will be described by taking “Daiken”, which is one of the weapons of the player character, as an example. FIGS. 4A to 4C are views showing a state where the player holds the core unit 70 with the right hand. In the figure, the upper part shows the front of the player, the lower part shows the rear, the right shows the right direction, and the left shows the left direction. The LED module 8 is installed in front of the player.

  First, when the player swings the core unit 70 or presses the + button 72g, the player character holds the large sword on his back in both hands. However, if the player performs an operation of holding the above-mentioned large sword during the movement operation of the player character (operation of the control stick 78a), a swing attack is performed immediately after taking out the large sword from the back as a “weapon removal attack”. . In the present embodiment, it is determined that the swing operation has been performed when the change in acceleration is equal to or greater than a certain threshold. In this embodiment, the swing direction is not used as a determination material for the presence or absence of a swing operation. However, the swing direction may be used as a determination material, and the swing is performed only when the swing is performed in a predetermined direction. You may make it judge that there existed operation.

  Then, after holding the large sword, when the player presses the A button 72d (corresponding to the operation element of the present invention) of the core unit 70, the player character plays an attack technique, but the posture (direction) of the core unit 70 Depending on the type of attack technique, the type of attack is different. In the present embodiment, three attack techniques are assigned according to the three postures of the core unit 70 shown in FIGS.

  When the player presses the A button 72d while holding the core unit 70 horizontally as shown in FIG. 5A (first posture), the player character performs “vertical cutting”. “Vertical cutting” is an attack technique in which a player character strikes a large sword toward the ground from above. FIG. 8 shows an example of a game screen including a figure in which the player character performs “vertical cutting”. The player character swings with a big sword with both hands as shown in FIG. 5A, and strikes it toward the ground as shown in FIG.

  When the player presses the A button 72d with the upper surface of the core unit 70 facing right as shown in FIG. 7B (second posture), the player character performs “slashing up”. “Slashing up” is an attack technique in which the player character swings the large sword from the right rear to the upper left. FIG. 9 shows an example of a game screen including a figure in which the player character performs “cutting up”. The player character holds the large sword with both hands as shown in FIG. 6A and holds it right rearward and swings it up diagonally leftward as shown in FIG.

  When the player presses the A button 72d with the top surface of the core unit 70 facing left as shown in FIG. 7C (third posture), the player character performs “nagashi”. “Nagashi” is an attack technique in which the player character swings a large sword forward from the left rear. FIG. 10 shows an example of a game screen including a figure in which the player character performs “pagging”. The player character holds the large sword with both hands as shown in FIG. 9A and holds it to the left rear, and swings it forward as shown in FIG.

  The player character performs a series of motions from the stance to the finish (follow-through) when the above-described attack technique is advanced. The player character control unit 52 does not accept an operation from the controller in principle during the motion of the attack technique, and accepts an operation for the next action of the player character after the motion ends.

  However, the operation for the next attack technique is accepted only during a certain period of time in the second half of the attack technique motion, and the operation of the next attack technique is accepted during this time period (continuous attack acceptance time period). The next attack technique can be sent out at shorter intervals. That is, of the previous attack technique motion, the last part (follow-through) executed after the continuous attack acceptance time period is omitted, and then the next attack technique motion starts. As a result, it seems that the previous attack technique and the next attack technique are performed in succession. The continuous attack does not increase the power of each attack technique, but has the advantage that “skies” are less likely to occur due to the short interval between techniques.

  However, in this embodiment, the same attack technique cannot be continuously issued as a continuous attack. Therefore, in order to keep making continuous attacks, it is necessary to change the posture of the core unit 70 between the postures shown in FIGS. In this embodiment, since the state in which the core unit 70 is held horizontally is set as a reference posture, the subsequent attack technique can be switched simply by tilting to the right by a predetermined degree or tilting to the left by a predetermined degree or more. Attack techniques with desired contents can be sent out. In this embodiment, the attacking technique can be switched by tilting the core unit 70 in the left-right direction from the reference posture, but the attacking technique may be switched by tilting in the front-rear direction.

  Further, if the player continues to press the A button 72d while holding the core unit 70 vertically (the imaging information calculation unit 74 provided on the front surface of the core unit 70 is facing upward), the player character performs “reserving action”. When the core unit 70 is swung or the A button 72d is released in a state where the force is accumulated, the “accumulation attack” is performed. The “accumulation attack” is an attack technique in which a player character swings a large sword back, accumulates power, and then strikes it toward the ground. This “pick-up attack” does not change the motion itself from the “vertical slash”, but the longer the piling-up time, the stronger the power and the greater the damage to the enemy character. This accumulation time is measured by a counter provided in advance.

  As described above, the attack technique is delivered by a single button operation (pressing of the A button 72d), but only by changing the attitude of the controller (core unit 70), one of a plurality of attack techniques can be selected. It is possible to select an attack technique even for a player who is not familiar with button operations. Further, the attack operation can be intuitively performed by relating the attack technique to the controller orientation (posture), such as cutting the controller to the right to cut from the right and to the left to cut from the left. Furthermore, by including the posture of the controller in the operation pattern, it is possible to set various attack techniques without being limited to the number of operators.

  Further, the detection of the attitude of the controller is more accurate than the detection of the swinging operation, and since the determination is finally made by a digital operation of pressing the A button 72d, malfunction is unlikely to occur, and the player Can avoid the stress. In addition, although it is activated also by swinging the core unit 70 only for the “pick-up”, the player's operation is stopped for a predetermined time by the “pick-up action” until just before the turn-off, so that malfunction is unlikely to occur. .

  As described above, some of the player character operations such as “pick-up” are set in two modes: an operation by swinging the core unit 70 and an operation by depressing the operator. A person can select a favorite one according to his / her preference. In particular, when the player desires only an operation by pressing the operation element, the controller 7 accepts an operation for selecting the mask mode setting (corresponding to the mask setting operation of the present invention, for example, the setting operation on the option screen) from the player. In this case, only the detection of the swing of the core unit 70 can be masked, and further malfunction can be eliminated. Here, the mask mode refers to a mode in which the player's swing operation is ignored.

  In addition to the above attack operations, an “evasion” operation is set in order to prevent an enemy attack during the battle. When the player presses the B button 72i of the core unit 70, the player character alternately “squats” and “rises” each time the player presses the B button 72i, thereby avoiding an enemy attack. Further, when the player performs the avoidance operation during the player character movement operation (operation of the control stick 78a), the player makes one turn from the head in the movement direction as “emergency avoidance”.

  FIG. 11 and FIG. 12 are flowcharts showing the player character weapon control process performed by the player character control unit 52. Here, the control of “Daiken”, which is one of the weapons of the player character, will be described as an example. This process is repeatedly executed, for example, every frame (1/60 second).

  First, in FIG. 11, it is determined whether or not the operation detection unit 50 detects ON (pressing) of the A button 72d (S11). Here, ON detection means not detecting the ON state but detecting the rising edge of the ON operation. When the ON state of the A button 72d is detected (YES in S11), it is determined whether or not the operation detection unit 50 detects that the core unit 70 is in the vertical state (S12). When detecting that the A button 72d is ON, the operation detection unit 50 determines the posture of the core unit 70 using the acceleration detected at this time and notifies the character control unit 52 of it.

  If the core unit 70 is in the vertical state (YES in S12), the counter is set to cause the player character to perform a “reserving action” (S13), and the accumulation flag is set (S14). When the core unit 70 is not in the vertical state (NO in S12), it is determined whether or not the operation detection unit 50 detects that the core unit 70 is in the horizontal state (S15). When the core unit 70 is in a horizontal state (YES in S15), the player character is caused to perform “vertical cutting” (S16). Details of the process of S16 will be described later with reference to FIG.

  When the core unit 70 is not in the horizontal state (NO in S15), it is determined whether or not the operation detection unit 50 detects that the core unit 70 is facing right (S17). If the core unit 70 is facing right (YES in S17), the player character is caused to perform “slashing” (S18). When the core unit 70 is not facing right (NO in S17), it is determined whether or not the operation detection unit 50 detects that the core unit 70 is facing left (S19). If the core unit 70 is facing left (YES in S19), the player character is caused to “snip off” (S20).

  For the “direction” of the core unit 70, a predetermined angle threshold value is set in advance, and when the detected inclination angle of the core unit 70 is larger than the angle threshold value, it may be determined as the right / left direction ( If it is below the threshold, it is determined to be in the horizontal state).

  On the other hand, if ON of the A button 72d is not detected (NO in S11), or if the core unit 70 is not in any of the states S12, S15, S17, and S19 (NO in S19), any processing is performed. Absent.

  Next, in FIG. 12A, it is determined whether or not the operation detection unit 50 detects that the A button 72d is turned off (released) (S25). When the OFF of the A button 72d is detected (YES in S25), it is determined whether or not the accumulation flag is set (S26). If the accumulation flag is set (YES in S26), the accumulation flag is reset (S27), and it is determined whether or not the accumulation time is 3 seconds or more (S28). When the accumulation time is 3 seconds or more (YES in S28), the player character is caused to perform “accumulation cutting” with a power corresponding to the length of the accumulation time (S29). If the accumulation time is less than 3 seconds (NO in S28), the player character is caused to perform “vertical cutting” (S30). After execution of S29 or S30, the counter is reset.

  Next, in FIG. 5B, it is determined whether or not the detection of the swing (swing) of the core unit 70 is masked (mask mode is set) (S31). If the detection of the swing is masked (YES in S31), the following processing is not performed to ignore the detection of the swing. In this process, the character control means 52 ignores even if the swing of the core unit 70 is detected, but it is set so that the operation detection unit 50 does not detect the swing of the core unit 70 itself. Also good.

If the detection of the swing is not masked (NO in S31), it is determined whether or not the swing is detected (S32). When the swing is detected (YES in S32), it is determined whether or not the accumulation flag is set (S33). If the accumulation flag is set (YES in S33), the accumulation flag is reset (S34), and it is determined whether or not the accumulation time is 3 seconds or more (S35). If the accumulation time is 3 seconds or more (YES in S35), the player character is caused to perform “accumulation cutting” with a power corresponding to the length of the accumulation time (S36). If the accumulation time is less than 3 seconds (NO in S35), the player character is caused to perform “vertical cutting” (S37). After execution of S36 or S37, the counter is reset. After the above processing is completed, the process returns from S11 in FIG.

  In addition, after the user's accumulation operation is accepted and the accumulation flag is set, the posture of the core unit 70 is in the vertical state during the accumulation operation (when the release of the A button 72d and the swing operation of the core unit 70 are not accepted). It may disappear. Even in this case, as long as the accumulation flag is set, it is determined that the accumulation operation is continued.

Next, the vertical cutting operation process executed in S16 of FIG. 11 will be described with reference to FIG.
As shown in FIG. 13A, when vertical cutting is performed (S16 in FIG. 11), first, the previous attack operation has already been performed, and the attack technique (first attack action) is being reproduced. It is determined whether or not (S161). If the attack technique is being reproduced (YES in S161), it is determined whether or not it is the continuous attack acceptance time zone (203 in FIG. 5B) (S162).

  If it is the continuous attack acceptance time zone (YES in S162), whether the attack technique (first attack action) being played is the same as the attack technique (second attack action) corresponding to the attitude of the core unit 70 or not. That is, it is determined whether or not the attack technique being reproduced is vertical slashing (S163). If the attack technique being played is not a vertical slash (NO in S163), the follow-through of the attack technique being played (202 in FIG. 5B) is omitted (S164), and "vertical slash" is performed on the character. (S165).

  On the other hand, when the attack technique is not being reproduced (NO in S161), the player character is caused to perform “vertical cutting” (S165). If NO in S162 (time periods indicated by 201a and 202 in FIG. 5B), or YES in S163, this process is terminated without causing the player character to perform “vertical cutting”. . Although only “vertical cutting” has been described here, the same processing is executed in the operation processing of S18 for “cutting up” and the operation processing of S20 for “slashing”.

  As shown in FIG. 13B, when the attack technique of the player character is performed once, the motion data of the attack technique having a predetermined action reproduction time 200 length is read out. The operation playback time 200 is composed of a main attack time zone 201 and a follow-through time zone 202. A predetermined time zone 201 b in the latter half of the main attack time zone 201 is a continuous attack acceptance time zone 203. As shown in the figure, when an attack operation by the player is performed in the continuous attack acceptance time zone 203, the operation in the follow-through time zone 202 is omitted, and the next attack technique of the player character following the main attack time zone 201 is omitted. Is started. On the other hand, if the attack operation by the player is not performed in the continuous attack acceptance time zone 203, for example, even if a continuous attack is attempted, the attack operation is performed in the predetermined time zone 201a or the follow-through time zone 202 in the first half of the main attack time zone 201. In the case of deviation, the next attack technique of the player character is not performed.

  In this embodiment, when the swing of the core unit 70 is accepted, the attack technique that the player character delivers is always “vertical slash” except in the case of “stub cut”, but as another embodiment of the present invention, Each time the swing operation is performed, the player character may send out “vertical slash”, “slash up”, and “nagashi” in order.

  Hereinafter, the processing in another embodiment will be described with reference to FIG. In this other embodiment, the order of attack techniques is set in advance in the player character control unit 52. Further, this process is executed by the player character control unit 52 when the accumulation flag is not set in the process performed in FIG. 12B (NO in S33).

  First, it is determined whether or not the attack technique is being reproduced (S41). If the attack technique is being reproduced (YES in S41), it is determined whether or not it is the continuous attack acceptance time zone (203 in FIG. 13B) (S42). If it is the continuous attack acceptance time zone (YES in S42), the follow-through of the attack technique being played is omitted (S43), and the type of attack technique in the next order of the attack technique currently being played is determined and determined. The attack technique is executed by the player character (S44). Thereafter, the determined attack technique type is stored (S45), and the process returns. The attack technique type stored in S45 is used when an attack technique is determined in S44.

  On the other hand, if the attack technique is not being reproduced (NO in S41), the stored attack technique type is returned to the initial setting (S46). If the attack technique type is the initial setting, the attack technique determined in S44 is always “vertical cutting”. Then, the character is caused to perform “vertical cutting” (S47). If it is not the continuous attack acceptance time zone (in the time zone indicated by 201a and 202 in FIG. 13B) (NO in S42), the attack technique type to be stored is reset to the initial setting (S48), and the character is attacked. This process is terminated without performing the technique.

  In the other embodiment, when the core unit 70 is shaken during the continuous attack reception time zone during the reproduction of the attack technique, the follow-through of the attack technique being reproduced is omitted, and “vertical cutting” and “cutting up” are performed. Any one of “Nagashi” is paid out in order. Therefore, in addition to the method of operating the A button 72d with the core unit 70 in a predetermined posture, a continuous attack can be sent out by an operation of shaking the core unit 70. Furthermore, since the “shaking operation” that is likely to be erroneously detected can be masked according to the user's setting operation, the purpose of preventing erroneous detection of the operation can be achieved while expanding the user's operation options.

  In the above-described other embodiments, “vertical slash”, “slash up”, and “nagashi” are sequentially delivered in S44, but may be randomly delivered from two techniques other than the attack technique currently being reproduced.

  In the present embodiment, the “large sword” is described as an example, but a weapon other than the “large sword” may be used. Moreover, it is not limited to the attack operation using the character's weapon, but may be an attack operation without a weapon such as “punch” and “kick”. In this case, “punch” or “kick” may be fed out from the direction in which the core unit 70 faces. Furthermore, it is not limited to the character's attacking action, but may be any action of the character operated by the player, such as a moving action.

In this embodiment, the attack technique is assigned to the combination of the posture of the A button 72d and the core unit 70, but may be assigned to another operation button instead of the A button 72d. An attack technique may be assigned to a combination of the number of operations of the A button 72d and the posture of the core unit 70. In this case, even if the core unit 70 is in the same posture, if the number of times the A button 72d is pressed is different, another attack technique is paid out. Further, an attack technique may be assigned to the operation of a plurality of operation buttons and the posture of the core unit 70. In the present embodiment, a total of four types of attack techniques are delivered by operating the A button 72d when the core unit 70 is in the vertical state, in the horizontal state, in the left direction, and in the right direction. More attack techniques may be sent out in association with the posture.

  In the present invention, a character possessing a weapon appears in the game image output to the monitor 2 and the character is set to attack with a weapon in the game image, but the character appears in the game image. Instead, it may be set such that the player himself attacks with a (virtual) weapon. In other words, the present invention can be applied to an action game in which a player character of a type in which a game image is drawn from the subjective viewpoint of the player does not appear. For example, a game in which a player himself holds a sword and cuts an enemy character. You may apply this invention. In any case, the player can play out a plurality of types of attack techniques with the same operation by changing the posture of the core unit 70. Since the operation of changing the posture of the core unit 70 can be easily performed with only one hand, the player can quickly put out different kinds of attack techniques and can also make the above-mentioned continuous attack.

  It should be noted that the weapon used by the player character can be purchased or produced by the player character at a store in the game, and the player can cause the player character to use his / her favorite weapon from a plurality of types of weapons.

  When playing this action game, the core unit 70 may be used for the movement control of the player character, and the subunit 76 may be used for the movement control of the virtual camera.

  In the present embodiment, the posture and swing of the core unit 70 are detected based on the acceleration of the core unit 70 detected by the acceleration sensor 701. However, the core unit 70 is detected using the speed detected by the acceleration sensor 701. 70 postures and swings may be detected. Further, the acceleration sensor 701 may detect both the acceleration and the speed, and the posture and swing of the core unit 70 may be detected based on both the acceleration and the speed. In addition, the structure which detects the attitude | position of the core unit 70 using another sensor may be sufficient, for example, the attitude | position of the core unit 70 may be detected based on the signal from the imaging information calculating part 74. FIG.

  In the present embodiment, the controller 7 transmits a signal from the acceleration sensor 70 to the game apparatus 3, and the game apparatus 3 (operation detection unit 50) detects the posture of the core unit 70 using this signal. However, the controller 7 may detect the posture of the core unit 70 and transmit the detection result to the game apparatus 3.

  Further, the present invention may be applied not only to a home game machine but also to an arcade game machine. Further, the present invention may be applied not only to a game machine in which the game machine main body and the controller are separated but also to a portable game machine in which the controller and the apparatus main body are integrated. Further, the present invention may be applied to a controller having a function of detecting a posture and such a controller connected to a personal computer.
