Abstract

Provided is a game device which enables a user to significantly change the line-of-sight direction of a viewpoint with relative ease, whilst ensuring intuitive operability. A movement detector (16) detects the movement of a game device (10). A first line-of-sight direction controller (52) updates the line-of-sight direction of a viewpoint on the basis of the detection result of the movement detector (16). In cases when a prescribed operation of an operating member is performed, a second line-of-sight direction controller (54) sets the line-of-sight direction of the viewpoint to a prescribed direction.

The control unit 11 determines the operation state of each operation member based on this information.
　動き検出部１６は、ゲーム装置１０の動きを検出するための一又は複数のセンサを含む。例えば、動き検出部１６は加速度センサ及びジャイロセンサの少なくとも一方を含む。 The motion detection unit 16 includes one or more sensors for detecting the motion of the game apparatus 10. For example, the motion detection unit 16 includes at least one of an acceleration sensor and a gyro sensor.
　加速度センサはゲーム装置１０の加速度を検出する。例えば、ゲーム装置１０を持っているユーザの動作によってゲーム装置１０に生じる加速度が加速度センサによって検出される。加速度センサは互いに直交する三つの軸方向（Ｘ軸方向、Ｙ軸方向、及びＺ軸方向）の加速度を検出する。図１に示すように、ゲーム装置１０の第２筐体２２は略矩形形状を有しており、例えば、Ｘ軸は第２筐体２２の長手方向に対応し、Ｚ軸は第２筐体２２の短手方向に対応する。また、Ｙ軸は第２筐体２２の法線方向に対応する。 The acceleration sensor detects the acceleration of the game apparatus 10. For example, an acceleration generated in the game apparatus 10 due to an operation of a user having the game apparatus 10 is detected by an acceleration sensor. The acceleration sensor detects accelerations in three axial directions (X-axis direction, Y-axis direction, and Z-axis direction) orthogonal to each other. As shown in FIG. 1, the second housing 22 of the game apparatus 10 has a substantially rectangular shape. For example, the X axis corresponds to the longitudinal direction of the second housing 22, and the Z axis is the second housing. This corresponds to 22 short directions. The Y axis corresponds to the normal direction of the second housing 22.
　ジャイロセンサはゲーム装置１０の角速度を検出する。例えば、ゲーム装置１０を持っているユーザの動作によってゲーム装置１０に生じる角速度がジャイロセンサによって検出される。ジャイロセンサは互いに直交する三つの軸（Ｘ軸、Ｙ軸、及びＺ軸）の角速度を検出する。すなわち、ジャイロセンサは、ゲーム装置１０がＸ軸を回転軸として回転した場合の単位時間当たりの回転量を検出する。同様に、ジャイロセンサは、ゲーム装置１０がＹ軸を回転軸として回転した場合の単位時間当たりの回転量を検出する。さらに、ジャイロセンサは、ゲーム装置１０がＺ軸を回転軸として回転した場合の単位時間当たりの回転量を検出する。 The gyro sensor detects the angular velocity of the game apparatus 10. For example, an angular velocity generated in the game apparatus 10 due to an operation of a user having the game apparatus 10 is detected by a gyro sensor. The gyro sensor detects angular velocities of three axes (X axis, Y axis, and Z axis) orthogonal to each other. That is, the gyro sensor detects the amount of rotation per unit time when the game apparatus 10 rotates about the X axis as a rotation axis. Similarly, the gyro sensor detects the amount of rotation per unit time when the game apparatus 10 rotates about the Y axis as a rotation axis. Further, the gyro sensor detects a rotation amount per unit time when the game apparatus 10 rotates about the Z axis as a rotation axis.
　加速度センサ又は／及びジャイロセンサの検出結果を示す情報は所定時間（例えば１／６０秒）ごとに制御部１１に供給される。制御部１１はこの情報に基づいてゲーム装置１０の姿勢（傾き）を判断する。 Information indicating the detection result of the acceleration sensor and / or gyro sensor is supplied to the control unit 11 every predetermined time (for example, 1/60 seconds). The control unit 11 determines the attitude (tilt) of the game apparatus 10 based on this information.
　例えば、制御部１１は加速度センサの検出結果に基づいてゲーム装置１０の姿勢（傾き）を判断する。例えば、制御部１１は、重力加速度がＸ軸方向、Ｙ軸方向、及びＺ軸方向の加速度としてどのように検出されているかに基づいて、ゲーム装置１０の姿勢（傾き）を判断する。 For example, the control unit 11 determines the attitude (tilt) of the game apparatus 10 based on the detection result of the acceleration sensor. For example, the control unit 11 determines the attitude (tilt) of the game apparatus 10 based on how the gravitational acceleration is detected as acceleration in the X-axis direction, the Y-axis direction, and the Z-axis direction.
　また例えば、制御部１１はジャイロセンサの検出結果に基づいてゲーム装置１０の姿勢（傾き）を判断する。例えば、制御部１１は、ジャイロセンサによって検出された各軸の角速度を積分することによって、各軸を回転軸としてゲーム装置１０がどの程度回転したかを判断する。 For example, the control unit 11 determines the attitude (tilt) of the game apparatus 10 based on the detection result of the gyro sensor. For example, the control unit 11 determines how much the game apparatus 10 has rotated about each axis as a rotation axis by integrating the angular velocity of each axis detected by the gyro sensor.
　出力部１７は表示部１８と音声出力部１９とを含む。表示部１８は制御部１１からの指示に従って画面を表示する。本実施形態の場合、表示部１８は第１表示部１８Ａ及び第２表示部１８Ｂを含む。音声出力部１９は制御部１１からの指示に従って音声を出力する。 The output unit 17 includes a display unit 18 and an audio output unit 19. The display unit 18 displays a screen according to instructions from the control unit 11. In the present embodiment, the display unit 18 includes a first display unit 18A and a second display unit 18B. The sound output unit 19 outputs sound according to an instruction from the control unit 11.

For example, a game in which a user's operation target moves in a virtual space is executed. Below, the case where the game in which the user character which acts according to a user's operation defeats an enemy character is performed is demonstrated.
　ゲーム装置１０では、上記のようなゲームのゲーム画面を生成するために、仮想空間がメインメモリに構築される。図４は仮想空間の一例を示す。図４に示す仮想空間３０は、お互いに直交する三つの座標軸（Ｘｗ軸、Ｙｗ軸、及びＺｗ軸）が設定された仮想的な３次元空間である。 In the game apparatus 10, a virtual space is constructed in the main memory in order to generate a game screen for the game as described above. FIG. 4 shows an example of the virtual space. A virtual space 30 shown in FIG. 4 is a virtual three-dimensional space in which three coordinate axes (Xw axis, Yw axis, and Zw axis) orthogonal to each other are set.
　図４に示す仮想空間３０には、床を示す床オブジェクト（以下、単に「床」と記載する。）３２Ａと、壁を示す壁オブジェクト（以下、単に「壁」と記載する。）３２Ｂと、が配置されている。さらに、仮想空間３０には、ユーザキャラクタを示すユーザキャラクタオブジェクト（以下、単に「ユーザキャラクタ」と記載する。）３４と、敵キャラクタを示す敵キャラクタオブジェクト（以下、単に「敵キャラクタ」と記載する。）３６と、が配置されている。ユーザキャラクタ３４はユーザの操作に従って行動する。例えば、ユーザの移動指示操作に従ってユーザキャラクタ３４は移動する。また図４では省略されているが、ユーザキャラクタ３４は武器（例えば銃）を所持しており、ユーザの攻撃指示操作に従って敵キャラクタ３６への攻撃を行う。敵キャラクタ３６は所定のアルゴリズムに従って自律的に行動する。敵キャラクタ３６は他のユーザによって操作されるようにしてもよい。 In the virtual space 30 shown in FIG. 4, a floor object (hereinafter simply referred to as “floor”) 32A indicating a floor, a wall object (hereinafter simply referred to as “wall”) 32B indicating a wall, Is arranged. Furthermore, in the virtual space 30, a user character object (hereinafter simply referred to as “user character”) 34 indicating a user character and an enemy character object (hereinafter simply referred to as “enemy character”) indicating an enemy character are described. 36) are arranged. The user character 34 behaves according to the user's operation. For example, the user character 34 moves according to the user's movement instruction operation. Although omitted in FIG. 4, the user character 34 possesses a weapon (for example, a gun), and attacks the enemy character 36 in accordance with the user's attack instruction operation. The enemy character 36 acts autonomously according to a predetermined algorithm. The enemy character 36 may be operated by another user.
　仮想空間３０には視点（仮想カメラ）が設定される。例えば、視点の位置４０はユーザキャラクタ３４の背後の上方に設定される。また、ユーザキャラクタ３４の足元位置が視点の注視位置４４として設定される。すなわち、視点の位置４０から注視位置４４（ユーザキャラクタ３４の足元位置）への方向が視点の視線方向４２として設定される。 A viewpoint (virtual camera) is set in the virtual space 30. For example, the viewpoint position 40 is set above and behind the user character 34. Further, the foot position of the user character 34 is set as the gaze position 44 of the viewpoint. That is, the direction from the viewpoint position 40 to the gaze position 44 (the foot position of the user character 34) is set as the viewpoint gaze direction 42.
　図５はユーザキャラクタ３４と視点との関係の一例を示す。図５に示すように、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の視線方向４２は設定される。視点はユーザキャラクタ３４の移動に従って移動するようになっており、ユーザキャラクタ３４と視点とは常に一定の位置関係を有するようになっている。その結果、ユーザキャラクタ３４の全身又は一部（例えば上半身）が常に視点の視野に含まれるようになっている。 FIG. 5 shows an example of the relationship between the user character 34 and the viewpoint. As shown in FIG. 5, the viewpoint line-of-sight direction 42 is set so that the XwZw plane component in the front direction 34 </ b> F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. The viewpoint moves according to the movement of the user character 34, and the user character 34 and the viewpoint always have a certain positional relationship. As a result, the whole body or a part (for example, the upper body) of the user character 34 is always included in the visual field of view.
　なお、視点の位置４０はユーザキャラクタ３４の背後の上方に設定されていなくてもよい。例えば、視点の位置４０はユーザキャラクタ３４の頭部内の位置（例えば、左目と右目との間の中間位置）に設定されるようにしてもよい。この場合、視点の視線方向４２はユーザキャラクタ３４の頭部の正面方向と略等しくなり、視点の視野はユーザキャラクタ３４の視野と略等しくなる。 It should be noted that the viewpoint position 40 does not have to be set above the user character 34. For example, the viewpoint position 40 may be set to a position within the head of the user character 34 (for example, an intermediate position between the left eye and the right eye). In this case, the visual line direction 42 of the viewpoint is substantially equal to the front direction of the head of the user character 34, and the visual field of the viewpoint is substantially equal to the visual field of the user character 34.
　視点から見た仮想空間３０を表すゲーム画面が表示部１８（例えば第１表示部１８Ａ）に表示される。図６はゲーム画面の一例を示す。図６に示すように、視点の視野画像がゲーム画面に表示される。視点の視野画像は一般的な３次元コンピュータグラフィックス技術を用いて生成される。すなわち、仮想空間３０内のオブジェクトの頂点の座標値をワールド座標系（ＸｗＹｗＺｗ座標系：図４参照）からスクリーン座標系（ＸｓＹｓ座標系）に変換することによって生成される。なお、スクリーン座標系とは、図６に示すように、ゲーム画面（視点の視野画像）の左上頂点を原点Ｏとし、右方向をＸｓ軸正方向とし、下方向をＹｓ軸正方向とするような座標系である。 A game screen representing the virtual space 30 viewed from the viewpoint is displayed on the display unit 18 (for example, the first display unit 18A). FIG. 6 shows an example of the game screen. As shown in FIG. 6, the visual field image of the viewpoint is displayed on the game screen. The visual field image of the viewpoint is generated using a general three-dimensional computer graphics technique. That is, it is generated by converting the coordinate value of the vertex of the object in the virtual space 30 from the world coordinate system (XwYwZw coordinate system: see FIG. 4) to the screen coordinate system (XsYs coordinate system). As shown in FIG. 6, the screen coordinate system is such that the upper left vertex of the game screen (viewpoint visual field image) is the origin O, the right direction is the Xs-axis positive direction, and the lower direction is the Ys-axis positive direction. Coordinate system.
　ゲーム装置１０では、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２がユーザの操作に従って変わるようになっている。以下、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を変えるためにユーザが行う操作について説明する。 In the game apparatus 10, the front direction 34 </ b> F and the visual line direction 42 of the user character 34 are changed according to the user's operation. Hereinafter, an operation performed by the user to change the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint will be described.
　図７及び図８は、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を変えるための操作の一例について説明するための図である。ゲーム装置１０では、ゲーム装置１０を傾けることによって、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２が変わるようになっている。 7 and 8 are diagrams for explaining an example of an operation for changing the front direction 34F and the viewpoint line-of-sight direction 42 of the user character 34. FIG. In the game apparatus 10, the front direction 34 </ b> F and the viewpoint line-of-sight direction 42 of the user character 34 are changed by tilting the game apparatus 10.
　図７（Ａ）は第２筐体２２を上方から見た様子を示す。図７（Ａ）は、矢印Ｒが示すようにユーザが第２筐体２２の右側端部を手前に引いた場合を示す。言い換えれば、図７（Ａ）は、Ｙ軸方向（第２筐体２２の法線方向）を回転軸としてゲーム装置１０を右回り（時計回り）に回転させるようにしてユーザがゲーム装置１０を傾けた場合を示す。 FIG. 7A shows the second housing 22 as viewed from above. FIG. 7A shows a case where the user pulls the right end of the second housing 22 forward as indicated by an arrow R. In other words, FIG. 7A shows that the user rotates the game apparatus 10 clockwise (clockwise) about the Y-axis direction (the normal direction of the second housing 22) as the rotation axis. Shown when tilted.
　図７（Ｂ）は、図７（Ａ）に示すようにユーザがゲーム装置１０を傾けた場合のユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化の一例を示す。なお、図７（Ｂ）は仮想空間３０を上方から見た様子を示す。また、図７（Ｂ）において、符号「３４ＦＡ」は変化前のユーザキャラクタ３４の正面方向３４Ｆを示し、符号「３４ＦＢ」は変化後のユーザキャラクタ３４の正面方向３４Ｆを示す。また、符号「４０Ａ」は変化前の視点の位置４０を示し、符号「４０Ｂ」は変化後の視点の位置４０を示す。同様に、符号「４２Ａ」は変化前の視点の視線方向４２を示し、符号「４２Ｂ」は変化後の視点の視線方向４２を示す。 FIG. 7B shows an example of changes in the front direction 34F and the visual line direction 42 of the user character 34 when the user tilts the game apparatus 10 as shown in FIG. 7A. FIG. 7B shows the virtual space 30 as viewed from above. Further, in FIG. 7B, the reference “34FA” indicates the front direction 34F of the user character 34 before the change, and the reference “34FB” indicates the front direction 34F of the user character 34 after the change. Reference numeral “40A” indicates the viewpoint position 40 before the change, and reference numeral “40B” indicates the viewpoint position 40 after the change. Similarly, the sign “42A” indicates the line-of-sight direction 42 of the viewpoint before the change, and the sign “42B” indicates the line-of-sight direction 42 of the viewpoint after the change.
　図７（Ａ）に示すようにユーザがゲーム装置１０を傾けた場合、図７（Ｂ）に示すように、ユーザキャラクタ３４の正面方向３４Ｆが方向３４ＦＡから方向３４ＦＢへと変化する。ここで、方向３４ＦＢは、方向３４ＦＡを右回り（時計回り）に角度θａだけ回転してなる方向である。すなわち、この場合、ユーザキャラクタ３４の正面方向３４Ｆは右回り（時計回り）に角度θａだけ変化することになる。なお、角度θａはゲーム装置１０の傾きの程度に応じて変化する。ゲーム装置１０の傾きの程度が大きいほど、角度θａは大きくなる。 When the user tilts the game apparatus 10 as shown in FIG. 7A, the front direction 34F of the user character 34 changes from the direction 34FA to the direction 34FB as shown in FIG. 7B. Here, the direction 34FB is a direction formed by rotating the direction 34FA clockwise (clockwise) by an angle θa. That is, in this case, the front direction 34F of the user character 34 changes clockwise (clockwise) by the angle θa. The angle θa changes according to the degree of inclination of the game apparatus 10. The angle θa increases as the degree of inclination of the game apparatus 10 increases.
　またこの場合、変更後のユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）に合わせて、視点の位置４０及び視線方向４２が変更される。すなわち、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の位置４０及び視線方向４２が変更される。この場合、視点の位置４０及び視線方向４２は注視位置４４を維持しつつ変更される。すなわち、視点の位置４０は、注視位置４４を中心として位置４０Ａを右回り（時計回り）に角度θだけ回転することによって得られる位置４０Ｂに変更される。また、視点の視線方向４２は位置４０Ｂから注視位置４４への方向に設定される。この場合、変更前の視点の視線方向４２（方向４２Ａ）と、変更後の視点の視線方向４２（方向４２Ｂ）との間の角度差は角度θａになる。 In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed in accordance with the front direction 34F (direction 34FB) of the user character 34 after the change. That is, the viewpoint position 40 and the line-of-sight direction 42 are changed so that the XwZw plane component in the front direction 34F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed while maintaining the gaze position 44. That is, the viewpoint position 40 is changed to a position 40B obtained by rotating the position 40A clockwise (clockwise) by the angle θ with the gaze position 44 as the center. Further, the visual line direction 42 of the viewpoint is set to the direction from the position 40B to the gaze position 44. In this case, the angle difference between the visual line direction 42 (direction 42A) of the viewpoint before change and the visual line direction 42 (direction 42B) of the viewpoint after change is the angle θa.
　図７（Ａ）と同様、図８（Ａ）は第２筐体２２を上方から見た様子を示す。図８（Ａ）は、矢印Ｌが示すようにユーザが第２筐体２２の左側端部を手前に引いた場合を示す。言い換えれば、図８（Ａ）は、Ｙ軸方向（第２筐体２２の法線方向）を回転軸としてゲーム装置１０を左回り（反時計回り）に回転させるようにしてユーザがゲーム装置１０を傾けた場合を示す。 As in FIG. 7A, FIG. 8A shows the second housing 22 as viewed from above. FIG. 8A shows a case where the user pulls the left end of the second housing 22 forward as indicated by the arrow L. In other words, FIG. 8A shows that the game device 10 is rotated by the user counterclockwise (counterclockwise) with the Y-axis direction (normal direction of the second housing 22) as the rotation axis. When tilted.
　図８（Ｂ）は、図８（Ａ）に示すようにユーザがゲーム装置１０を傾けた場合のユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化の一例を示す。図７（Ｂ）と同様、図８（Ｂ）は仮想空間３０を上方から見た様子を示す。符号「３４ＦＡ」は変化前のユーザキャラクタ３４の正面方向３４Ｆを示し、符号「３４ＦＢ」は変化後のユーザキャラクタ３４の正面方向３４Ｆを示す。また、符号「４０Ａ」は変化前の視点の位置４０を示し、符号「４０Ｂ」は変化後の視点の位置４０を示す。同様に、符号「４２Ａ」は変化前の視点の視線方向４２を示し、符号「４２Ｂ」は変化後の視点の視線方向４２を示す。 FIG. 8B shows an example of changes in the front direction 34F and the viewpoint line-of-sight direction 42 of the user character 34 when the user tilts the game apparatus 10 as shown in FIG. 8A. Similar to FIG. 7B, FIG. 8B shows a state in which the virtual space 30 is viewed from above. Reference sign “34FA” indicates the front direction 34F of the user character 34 before the change, and reference sign “34FB” indicates the front direction 34F of the user character 34 after the change. Reference numeral “40A” indicates the viewpoint position 40 before the change, and reference numeral “40B” indicates the viewpoint position 40 after the change. Similarly, the sign “42A” indicates the line-of-sight direction 42 of the viewpoint before the change, and the sign “42B” indicates the line-of-sight direction 42 of the viewpoint after the change.
　図８（Ａ）に示すようにユーザがゲーム装置１０を傾けた場合、図８（Ｂ）に示すように、ユーザキャラクタ３４の正面方向３４Ｆが方向３４ＦＡから方向３４ＦＢへと変化する。ここで、方向３４ＦＢは、方向３４ＦＡを左回り（反時計回り）に角度θａだけ回転してなる方向である。すなわち、この場合、ユーザキャラクタ３４の正面方向３４Ｆは左回り（反時計回り）に角度θａだけ変化することになる。なお、角度θａはゲーム装置１０の傾きの程度に応じて変化する。ゲーム装置１０の傾きの程度が大きいほど、角度θａは大きくなる。 8A, when the user tilts the game apparatus 10, as shown in FIG. 8B, the front direction 34F of the user character 34 changes from the direction 34FA to the direction 34FB. Here, the direction 34FB is a direction formed by rotating the direction 34FA counterclockwise (counterclockwise) by an angle θa. That is, in this case, the front direction 34F of the user character 34 changes counterclockwise (counterclockwise) by the angle θa. The angle θa changes according to the degree of inclination of the game apparatus 10. The angle θa increases as the degree of inclination of the game apparatus 10 increases.
　またこの場合、変更後のユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）に合わせて、視点の位置４０及び視線方向４２が変更される。すなわち、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の位置４０及び視線方向４２が変更される。この場合、視点の位置４０及び視線方向４２は注視位置４４を維持しつつ変更される。すなわち、視点の位置４０は、注視位置４４を中心として位置４０Ａを左回り（反時計回り）に角度θａだけ回転することによって得られる位置４０Ｂに変更される。また、視点の視線方向４２は位置４０Ｂから注視位置４４への方向に設定される。この場合、変更前の視点の視線方向４２（方向４２Ａ）と、変更後の視点の視線方向４２（方向４２Ｂ）との間の角度差は角度θａになる。 In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed in accordance with the front direction 34F (direction 34FB) of the user character 34 after the change. That is, the viewpoint position 40 and the line-of-sight direction 42 are changed so that the XwZw plane component in the front direction 34F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed while maintaining the gaze position 44. That is, the viewpoint position 40 is changed to a position 40B obtained by rotating the position 40A counterclockwise (counterclockwise) by the angle θa with the gaze position 44 as the center. Further, the visual line direction 42 of the viewpoint is set to the direction from the position 40B to the gaze position 44. In this case, the angle difference between the visual line direction 42 (direction 42A) of the viewpoint before change and the visual line direction 42 (direction 42B) of the viewpoint after change is the angle θa.
　以上のように、ゲーム装置１０では、ゲーム装置１０を傾けるという直感的な操作によってユーザはユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を変更できるようになっている。しかしながら、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を大きく変更したい場合、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化量（上記角度θａ）を大きくするために、ユーザはゲーム装置１０を大きく傾けなければならない。この点、ゲーム装置１０では、ユーザが比較的簡易にユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を大きく変更できるようになっている。 As described above, in the game apparatus 10, the user can change the front direction 34 </ b> F and the viewpoint line-of-sight direction 42 of the user character 34 by an intuitive operation of tilting the game apparatus 10. However, when it is desired to greatly change the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint, in order to increase the amount of change (the angle θa) of the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint, the user The game apparatus 10 must be tilted greatly. In this regard, in the game apparatus 10, the user can change the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint largely easily.
　具体的には、ゲーム装置１０では、ボタン１５Ｒ，１５Ｌを押下することによって、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を大きく変更できるようになっている。図９及び図１０は、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を大きく変更するための操作の一例について説明するための図である。 Specifically, in the game apparatus 10, by pressing the buttons 15R and 15L, the front direction 34F and the visual line direction 42 of the user character 34 can be changed greatly. 9 and 10 are diagrams for explaining an example of an operation for largely changing the front direction 34F and the visual line direction 42 of the user character 34. FIG.
　なお、図７，８（Ｂ）と同様、図９及び図１０は仮想空間３０を上方から見た様子を示す。符号「３４ＦＡ」は変化前のユーザキャラクタ３４の正面方向３４Ｆを示し、符号「３４ＦＢ」は変化後のユーザキャラクタ３４の正面方向３４Ｆを示す。また、符号「４０Ａ」は変化前の視点の位置４０を示し、符号「４０Ｂ」は変化後の視点の位置４０を示す。同様に、符号「４２Ａ」は変化前の視点の視線方向４２を示し、符号「４２Ｂ」は変化後の視点の視線方向４２を示す。 Note that, as in FIGS. 7 and 8B, FIGS. 9 and 10 show the virtual space 30 as viewed from above. Reference sign “34FA” indicates the front direction 34F of the user character 34 before the change, and reference sign “34FB” indicates the front direction 34F of the user character 34 after the change. Reference numeral “40A” indicates the viewpoint position 40 before the change, and reference numeral “40B” indicates the viewpoint position 40 after the change. Similarly, the sign “42A” indicates the line-of-sight direction 42 of the viewpoint before the change, and the sign “42B” indicates the line-of-sight direction 42 of the viewpoint after the change.
　図９は、ボタン１５Ｒが押下された場合のユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化の一例を示す。ボタン１５Ｒが押下された場合、図９に示すように、ユーザキャラクタ３４の正面方向３４Ｆが方向３４ＦＡから方向３４ＦＢへと変化する。ここで、方向３４ＦＢは、方向３４ＦＡを右回り（時計回り）に角度θｂだけ回転してなる方向である。すなわち、この場合、ユーザキャラクタ３４の正面方向３４Ｆは右回り（時計回り）に角度θｂだけ変化することになる。なお、角度θｂは比較的大きい一定の角度であり、例えば角度θｂは９０度である。 FIG. 9 shows an example of changes in the front direction 34F and the viewing direction 42 of the user character 34 when the button 15R is pressed. When the button 15R is pressed, as shown in FIG. 9, the front direction 34F of the user character 34 changes from the direction 34FA to the direction 34FB. Here, the direction 34FB is a direction formed by rotating the direction 34FA clockwise (clockwise) by an angle θb. That is, in this case, the front direction 34F of the user character 34 changes clockwise (clockwise) by the angle θb. The angle θb is a relatively large constant angle, for example, the angle θb is 90 degrees.
　またこの場合、変更後のユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）に合わせて、視点の位置４０及び視線方向４２が変更される。すなわち、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の位置４０及び視線方向４２が変更される。視点の位置４０及び視線方向４２は注視位置４４を維持しつつ変更される。具体的には、視点の位置４０は、注視位置４４を中心として位置４０Ａを右回り（時計回り）に角度θｂ（９０度）だけ回転してなる位置４０Ｂに変更される。また、視点の視線方向４２は位置４０Ｂから注視位置４４への方向に設定される。この場合、変更前の視点の視線方向４２（方向４２Ａ）と、変更後の視点の視線方向４２（方向４２Ｂ）との間の角度差は角度θｂ（９０度）になる。 In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed in accordance with the front direction 34F (direction 34FB) of the user character 34 after the change. That is, the viewpoint position 40 and the line-of-sight direction 42 are changed so that the XwZw plane component in the front direction 34F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. The viewpoint position 40 and the line-of-sight direction 42 are changed while the gaze position 44 is maintained. Specifically, the viewpoint position 40 is changed to a position 40B obtained by rotating the position 40A clockwise (clockwise) by an angle θb (90 degrees) with the gaze position 44 as the center. Further, the visual line direction 42 of the viewpoint is set to the direction from the position 40B to the gaze position 44. In this case, the angle difference between the line-of-sight direction 42 (direction 42A) of the viewpoint before the change and the line-of-sight direction 42 (direction 42B) of the viewpoint after the change is an angle θb (90 degrees).
　なお、ユーザがさらにボタン１５Ｒを押下すると、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２が右回り（時計回り）にさらに角度θｂ（９０度）だけ変化するようになる。 When the user further presses the button 15R, the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint change further clockwise (clockwise) by an angle θb (90 degrees).
　図１０は、ボタン１５Ｌが押下された場合のユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化の一例を示す。ボタン１５Ｌが押下された場合、図１０に示すように、ユーザキャラクタ３４の正面方向３４Ｆが方向３４ＦＡから方向３４ＦＢへと変化する。ここで、方向３４ＦＢは、方向３４ＦＡを左回り（反時計回り）に角度θｂだけ回転してなる方向である。すなわち、この場合、ユーザキャラクタ３４の正面方向３４Ｆは左回り（反時計回り）に角度θｂだけ変化することになる。なお先述したように、角度θｂは比較的大きい一定の角度であり、例えば角度θｂは９０度である。 FIG. 10 shows an example of changes in the front direction 34F and the viewing direction 42 of the user character 34 when the button 15L is pressed. When the button 15L is pressed, as shown in FIG. 10, the front direction 34F of the user character 34 changes from the direction 34FA to the direction 34FB. Here, the direction 34FB is a direction formed by rotating the direction 34FA counterclockwise (counterclockwise) by an angle θb. That is, in this case, the front direction 34F of the user character 34 changes counterclockwise (counterclockwise) by the angle θb. As described above, the angle θb is a relatively large constant angle, for example, the angle θb is 90 degrees.
　またこの場合、変更後のユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）に合わせて、視点の位置４０及び視線方向４２が変更される。すなわち、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の位置４０及び視線方向４２が変更される。視点の位置４０及び視線方向４２は注視位置４４を維持しつつ変更される。具体的には、視点の位置４０は、注視位置４４を中心として位置４０Ａを左回り（反時計回り）に角度θｂ（９０度）だけ回転してなる位置４０Ｂに変更される。また、視点の視線方向４２は位置４０Ｂから注視位置４４への方向に設定される。この場合、変更前の視点の視線方向４２（方向４２Ａ）と、変更後の視点の視線方向４２（方向４２Ｂ）との間の角度差は角度θｂ（９０度）になる。 In this case, the viewpoint position 40 and the line-of-sight direction 42 are changed in accordance with the front direction 34F (direction 34FB) of the user character 34 after the change. That is, the viewpoint position 40 and the line-of-sight direction 42 are changed so that the XwZw plane component in the front direction 34F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. The viewpoint position 40 and the line-of-sight direction 42 are changed while the gaze position 44 is maintained. Specifically, the viewpoint position 40 is changed to a position 40B obtained by rotating the position 40A counterclockwise (counterclockwise) by an angle θb (90 degrees) with the gaze position 44 as the center. Further, the visual line direction 42 of the viewpoint is set to the direction from the position 40B to the gaze position 44. In this case, the angle difference between the line-of-sight direction 42 (direction 42A) of the viewpoint before the change and the line-of-sight direction 42 (direction 42B) of the viewpoint after the change is an angle θb (90 degrees).
　なお、ユーザがさらにボタン１５Ｌを押下すると、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２が左回り（反時計回り）にさらに角度θｂ（９０度）だけ変化するようになる。 When the user further presses the button 15L, the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint change further counterclockwise (counterclockwise) by an angle θb (90 degrees).
　ゲーム装置１０によれば、以上のような構成を備えることにより、ボタン１５Ｒ，１５Ｌを押下するという比較的簡易な操作によってユーザはユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を比較的大きい角度θｂ（９０度）変更できるようになっている。 According to the game device 10, by providing the above configuration, the user can relatively increase the front direction 34 </ b> F and the viewpoint line-of-sight direction 42 of the user character 34 by a relatively simple operation of pressing the buttons 15 </ b> R and 15 </ b> L. The angle θb (90 degrees) can be changed.
　ところで、視点の視野角は、ボタン１５Ｒ，１５Ｌが押下された場合における視点の視線方向４２の変化量（上記角度θｂ：９０度）以上の角度に設定される。例えば、視点の視野角は１２０度に設定される。このように視点の視野角が設定されていることによって、視点の視線方向４２が大きく変化した場合であっても、変化前の視点の視野の一部が変化後の視点の視野に含まれるようになる。その結果、視点の視線方向４２がどのように変化したのか（すなわち、視点の視野がどのように変化したのか）をユーザが把握し易くなる。 By the way, the viewing angle of the viewpoint is set to an angle equal to or greater than the amount of change in the viewing direction 42 of the viewpoint when the buttons 15R and 15L are pressed (the angle θb: 90 degrees). For example, the viewing angle of the viewpoint is set to 120 degrees. By setting the viewing angle of the viewpoint in this way, even when the viewing direction 42 of the viewpoint changes significantly, a part of the viewing field before the change is included in the viewing field after the change. become. As a result, it becomes easier for the user to understand how the viewing direction 42 of the viewpoint has changed (that is, how the visual field of the viewpoint has changed).
　ここで、以上に説明したような機能を実現するための構成について説明する。図１１は、ゲーム装置１０で実現される機能のうち、本発明に関連する機能を示す機能ブロック図である。図１１に示すように、ゲーム装置１０は、操作部１５、動き検出部１６、ゲームデータ記憶部５０、第１の視線方向制御部５２、第２の視線方向制御部５４、及び表示制御部５６を含む。操作部１５及び動き検出部１６は、図３における操作部１５及び動き検出部１６である。ゲームデータ記憶部５０は例えば記憶部１２又は／及びゲームメモリカードによって実現され、第１の視線方向制御部５２、第２の視線方向制御部５４、及び表示制御部５６は制御部１１がプログラムを実行することによって実現される。すなわち、制御部１１がプログラムを実行することによって、制御部１１が第１の視線方向制御部５２、第２の視線方向制御部５４、及び表示制御部５６として機能する。 Here, a configuration for realizing the functions described above will be described. FIG. 11 is a functional block diagram showing functions related to the present invention among the functions realized by the game apparatus 10. As shown in FIG. 11, the game apparatus 10 includes an operation unit 15, a motion detection unit 16, a game data storage unit 50, a first gaze direction control unit 52, a second gaze direction control unit 54, and a display control unit 56. including. The operation unit 15 and the motion detection unit 16 are the operation unit 15 and the motion detection unit 16 in FIG. The game data storage unit 50 is realized by, for example, the storage unit 12 and / or a game memory card, and the control unit 11 has a program for the first gaze direction control unit 52, the second gaze direction control unit 54, and the display control unit 56. It is realized by executing. That is, when the control unit 11 executes the program, the control unit 11 functions as the first gaze direction control unit 52, the second gaze direction control unit 54, and the display control unit 56.
　まず、ゲームデータ記憶部５０について説明する。ゲームデータ記憶部５０はゲームを実行するために必要なゲームデータを記憶する。 First, the game data storage unit 50 will be described. The game data storage unit 50 stores game data necessary for executing the game.
　例えば、ゲームの現在の状況を示すゲーム状況データがゲームデータ記憶部５０に記憶される。具体的には、下記に示すようなデータがゲーム状況データに含まれる。
・ユーザキャラクタ３４の状態データ（位置、正面方向、及び姿勢等）
・敵キャラクタ３６の状態データ（位置、正面方向、及び姿勢等）
・視点の状態データ（位置４０、視線方向４２、及び視野角等） For example, game situation data indicating the current situation of the game is stored in the game data storage unit 50. Specifically, data as shown below is included in the game situation data.
-State data of the user character 34 (position, front direction, posture, etc.)
・ Status data of enemy character 36 (position, front direction, posture, etc.)
・ Viewpoint state data (position 40, line-of-sight direction 42, viewing angle, etc.)
　第１の視線方向制御部５２について説明する。第１の視線方向制御部５２は、動き検出部１６（ジャイロセンサ又は／及び加速度センサ）の検出結果に基づいて、視点の視線方向４２を更新する。第１の視線方向制御部５２は、図７，８（Ｂ）において説明した視点の視線方向４２の制御に対応している。 The first line-of-sight direction control unit 52 will be described. The first line-of-sight direction control unit 52 updates the line-of-sight direction 42 of the viewpoint based on the detection result of the motion detection unit 16 (gyro sensor or / and acceleration sensor). The first line-of-sight direction control unit 52 corresponds to the control of the line-of-sight direction 42 of the viewpoint described with reference to FIGS.
　例えば、第１の視線方向制御部５２はゲーム装置１０の傾きを動き検出部１６の検出結果に基づいて判断する。そして、第１の視線方向制御部５２は視点の視線方向４２をゲーム装置１０の傾きの方向及び程度に基づいて更新する（図７，８（Ｂ）参照）。 For example, the first line-of-sight direction control unit 52 determines the inclination of the game apparatus 10 based on the detection result of the motion detection unit 16. Then, the first line-of-sight direction control unit 52 updates the line-of-sight direction 42 of the viewpoint based on the direction and degree of inclination of the game apparatus 10 (see FIGS. 7 and 8B).
　第２の視線方向制御部５４について説明する。第２の視線方向制御部５４は、ゲーム装置１０に備えられる所定の操作部材（すなわち、操作部１５に含まれる操作部材のうちの所定の操作部材）に関する所定操作が行われた場合に、視点の視線方向４２を所定方向に設定する。第２の視線方向制御部５４は、図９，１０において説明した視点の視線方向４２の制御に対応している。 The second line-of-sight direction control unit 54 will be described. The second line-of-sight direction control unit 54 performs a viewpoint when a predetermined operation related to a predetermined operation member (that is, a predetermined operation member among the operation members included in the operation unit 15) provided in the game apparatus 10 is performed. Is set to a predetermined direction. The second gaze direction control unit 54 corresponds to the control of the gaze direction 42 of the viewpoint described with reference to FIGS.
　「所定の操作部材」とは、例えばボタンであり、「所定操作」とは、例えばボタンの押下操作である。本実施形態の場合、ボタン１５Ｒ，１５Ｌが「所定の操作部材」に相当し、ボタン１５Ｒ，１５Ｌの押下操作が「所定操作」に相当する。なお、「所定の操作部材」はボタン以外の操作部材であってもよい。例えば、「所定の操作部材」はスティックであってもよく、「所定操作」はスティックの傾倒操作であってもよい。 The “predetermined operation member” is, for example, a button, and the “predetermined operation” is, for example, a button pressing operation. In the present embodiment, the buttons 15R and 15L correspond to “predetermined operation members”, and the pressing operation of the buttons 15R and 15L corresponds to “predetermined operation”. The “predetermined operation member” may be an operation member other than a button. For example, the “predetermined operation member” may be a stick, and the “predetermined operation” may be a tilting operation of the stick.
　また、「所定方向」とは、所定操作が行われた場合における視点の視線方向４２との間の角度差が所定角度であるような方向である。本実施形態の場合、図９，１０における角度θｂ（９０度）が「所定角度」に相当し、方向４２Ｂが「所定方向」に相当する。 Further, the “predetermined direction” is a direction in which an angle difference from the visual line direction 42 of the viewpoint when a predetermined operation is performed is a predetermined angle. In the present embodiment, the angle θb (90 degrees) in FIGS. 9 and 10 corresponds to a “predetermined angle”, and the direction 42B corresponds to a “predetermined direction”.
　表示制御部５６について説明する。表示制御部５６は、視点から見た仮想空間３０を表すゲーム画面を表示部１８に表示させる。例えば、表示制御部５６は視点の視野画像をＶＲＡＭ上に生成する。ＶＲＡＭ上に生成された視野画像はゲーム画面として表示部１８に表示される。 The display control unit 56 will be described. The display control unit 56 causes the display unit 18 to display a game screen representing the virtual space 30 viewed from the viewpoint. For example, the display control unit 56 generates a visual field image of the viewpoint on the VRAM. The visual field image generated on the VRAM is displayed on the display unit 18 as a game screen.
　次に、上記の機能ブロックを実現するためにゲーム装置１０で実行される処理の一例について説明する。図１２は、ゲーム装置１０で所定時間（例えば１／６０秒）ごとに実行される処理のうち、本発明に関連する処理を主に示すフロー図である。制御部１１が図１２に示す処理をプログラムに従って実行することによって、制御部１１は第１の視線方向制御部５２、第２の視線方向制御部５４、及び表示制御部５６として機能する。 Next, an example of processing executed by the game apparatus 10 in order to realize the above functional block will be described. FIG. 12 is a flowchart mainly showing processing related to the present invention among processing executed every predetermined time (for example, 1/60 second) in the game apparatus 10. When the control unit 11 executes the processing shown in FIG. 12 according to the program, the control unit 11 functions as the first gaze direction control unit 52, the second gaze direction control unit 54, and the display control unit 56.
　図１２に示すように、まず制御部１１は所定ボタンが押下されたか否かを判定する（Ｓ１０１）。例えば、制御部１１はボタン１５Ｒ，１５Ｌのいずれかが押下されたか否かを判定する。所定ボタンが押下されていないと判定された場合、制御部１１は、動き検出部１６の検出結果に基づいて、ゲーム装置１０が傾けられたか否かを判定する（Ｓ１０２）。 As shown in FIG. 12, the control unit 11 first determines whether or not a predetermined button has been pressed (S101). For example, the control unit 11 determines whether any of the buttons 15R and 15L is pressed. When it is determined that the predetermined button has not been pressed, the control unit 11 determines whether or not the game apparatus 10 is tilted based on the detection result of the motion detection unit 16 (S102).
　ゲーム装置１０が傾けられたと判定された場合、制御部１１はユーザキャラクタ３４の向きを更新する（Ｓ１０３）。例えば図７，８（Ｂ）に示したように、制御部１１は、ユーザキャラクタ３４の正面方向３４Ｆを、「現在の正面方向３４Ｆから、ゲーム装置１０の傾きの方向に対応する方向に、ゲーム装置１０の傾きの程度に対応する角度θａだけ回転してなる方向」に更新する。 When it is determined that the game apparatus 10 is tilted, the control unit 11 updates the direction of the user character 34 (S103). For example, as shown in FIGS. 7 and 8B, the control unit 11 changes the front direction 34F of the user character 34 from “the current front direction 34F to the direction corresponding to the direction of the inclination of the game apparatus 10”. The direction is updated to “a direction rotated by an angle θa corresponding to the degree of inclination of the apparatus 10”.
　また、制御部１１は視点の位置４０及び視線方向４２を更新する（Ｓ１０４）。例えば図７，８（Ｂ）に示したように、制御部１１は、ステップＳ１０３で更新されたユーザキャラクタ３４の正面方向３４Ｆに合わせて、視点の位置４０及び視線方向４２を更新する。 Further, the control unit 11 updates the viewpoint position 40 and the line-of-sight direction 42 (S104). For example, as illustrated in FIGS. 7 and 8B, the control unit 11 updates the viewpoint position 40 and the line-of-sight direction 42 in accordance with the front direction 34F of the user character 34 updated in step S103.
　なお、ステップＳ１０２において、ゲーム装置１０が傾けられていないと判定された場合、制御部１１はステップＳ１０３，Ｓ１０４の処理を実行することなく、後述のステップＳ１０７の処理を実行する。 If it is determined in step S102 that the game apparatus 10 is not tilted, the control unit 11 executes the process of step S107 described later without executing the processes of steps S103 and S104.
　また、ステップＳ１０１において、所定ボタンが押下されたと判定された場合、制御部１１はユーザキャラクタ３４の向きを所定方向に設定する（Ｓ１０５）。例えば図９，１０に示したように、制御部１１は、ユーザキャラクタ３４の正面方向３４Ｆを、「現在の正面方向３４Ｆから、押下された所定ボタンに対応する方向に、角度θｂ（９０度）だけ回転してなる方向」に設定する。 If it is determined in step S101 that the predetermined button has been pressed, the control unit 11 sets the direction of the user character 34 to a predetermined direction (S105). For example, as illustrated in FIGS. 9 and 10, the control unit 11 changes the front direction 34 </ b> F of the user character 34 to “the angle θb (90 degrees) from the current front direction 34 </ b> F to the direction corresponding to the predetermined button pressed. "Direction of rotation".
　また、制御部１１は視点の位置４０を更新し、視点の視線方向４２を所定方向に設定する（Ｓ１０６）。例えば図９，１０に示したように、制御部１１は、ステップＳ１０５で更新されたユーザキャラクタ３４の正面方向３４Ｆに合わせて、視点の位置４０及び視線方向４２を設定する。 Further, the control unit 11 updates the viewpoint position 40 and sets the viewpoint line-of-sight direction 42 to a predetermined direction (S106). For example, as illustrated in FIGS. 9 and 10, the control unit 11 sets the viewpoint position 40 and the line-of-sight direction 42 according to the front direction 34 </ b> F of the user character 34 updated in step S <b> 105.
　ステップＳ１０４又はＳ１０６の処理が実行された後、制御部１１はゲームキャラクタの状態データを更新する（Ｓ１０７）。例えば、制御部１１は、ユーザの移動指示操作又は攻撃指示操作に従って、ユーザキャラクタ３４の位置を更新したり、攻撃動作を行うようにユーザキャラクタ３４の姿勢を更新したりする。また、制御部１１は、所定のアルゴリズムに従って、敵キャラクタ３６の位置を更新したり、ユーザキャラクタ３４への攻撃動作を行うように敵キャラクタ３６の姿勢を更新したりする。 After the process of step S104 or S106 is executed, the control unit 11 updates the state data of the game character (S107). For example, the control unit 11 updates the position of the user character 34 or updates the posture of the user character 34 so as to perform an attack action according to the user's movement instruction operation or attack instruction operation. In addition, the control unit 11 updates the position of the enemy character 36 or updates the posture of the enemy character 36 so as to perform an attacking action on the user character 34 according to a predetermined algorithm.
　ステップＳ１０７の処理が実行された後、制御部１１はゲーム画面を更新する（Ｓ１０８）。制御部１１は、視点から見た仮想空間３０を表す画像をＶＲＡＭ上に生成する。そして、ＶＲＡＭ上に生成された画像がゲーム画面として表示部１８に表示される。以上で図１２に示す処理の説明を終了する。 After the process of step S107 is executed, the control unit 11 updates the game screen (S108). The control unit 11 generates an image representing the virtual space 30 viewed from the viewpoint on the VRAM. Then, the image generated on the VRAM is displayed on the display unit 18 as a game screen. This is the end of the description of the processing illustrated in FIG.
　以上に説明した第１実施形態に係るゲーム装置１０では、ゲーム装置１０を傾けるという直感的な操作によって、ユーザがユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を変えることができるようになっている。また、ゲーム装置１０では、ボタン１５Ｒ，１５Ｌを押下するという比較的簡易な操作によって、ユーザがユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を大きく変えることができるようになっている。ゲーム装置１０によれば、直感的な操作性を担保しつつ、ユーザが比較的簡易に視点の視線方向４２を大きく変更できるようにすることが可能になる。 In the game device 10 according to the first embodiment described above, the user can change the front direction 34F and the visual line direction 42 of the viewpoint of the user character 34 by an intuitive operation of tilting the game device 10. ing. Further, in the game apparatus 10, the user can change the front direction 34 </ b> F and the viewpoint line-of-sight direction 42 of the user character 34 by a relatively simple operation of pressing the buttons 15 </ b> R and 15 </ b> L. According to the game apparatus 10, it is possible to allow the user to greatly change the visual line direction 42 of the viewpoint relatively easily while ensuring intuitive operability.
　［第２実施形態］次に、本発明の第２実施形態について説明する。本発明の第２実施形態に係るゲーム装置１０の外観及びハードウェア構成等は第１実施形態と同様である（図１～図３参照）。また、第２実施形態に係るゲーム装置１０においても、第１実施形態と同様のゲームが実行され、第１実施形態と同様の機能ブロックが実現される（図１１参照）。 [Second Embodiment] Next, a second embodiment of the present invention will be described. The appearance and hardware configuration of the game apparatus 10 according to the second embodiment of the present invention are the same as those of the first embodiment (see FIGS. 1 to 3). Also, in the game device 10 according to the second embodiment, the same game as that in the first embodiment is executed, and the same functional blocks as those in the first embodiment are realized (see FIG. 11).
　第２実施形態では、仮想空間３０の領域ごとに基本方向が設定され、この基本方向に基づいて、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２が制御される。この点で第２実施形態は第１実施形態と異なる。 In the second embodiment, a basic direction is set for each region of the virtual space 30, and the front direction 34F of the user character 34 and the visual line direction 42 of the viewpoint are controlled based on the basic direction. In this respect, the second embodiment is different from the first embodiment.
　図１３は、仮想空間３０の領域ごとに設定される基本方向の一例について説明するための図である。図１３に示す例では複数の領域６０Ａ，６０Ｂ，６０Ｃ，６０Ｄ，６０Ｅが設定されている。また、領域６０Ａには基本方向６２Ａが設定されている。基本方向６２Ａは、領域６０Ａにおけるユーザキャラクタ３４の基本的な進行方向である。同様に、領域６０Ｂ，６０Ｃ，６０Ｄ，６０Ｅには、それぞれ、基本方向６２Ｂ，６２Ｃ，６２Ｄ，６２Ｅが設定されている。なお以下では、領域６０Ａ～６０Ｅのことを総称して「領域６０」と記載する場合がある。同様に、基本方向６２Ａ～６２Ｅのことを総称して「基本方向６２」と記載する場合がある。 FIG. 13 is a diagram for explaining an example of a basic direction set for each region of the virtual space 30. FIG. In the example shown in FIG. 13, a plurality of areas 60A, 60B, 60C, 60D, and 60E are set. A basic direction 62A is set in the area 60A. The basic direction 62A is a basic traveling direction of the user character 34 in the region 60A. Similarly, basic directions 62B, 62C, 62D, and 62E are set in the regions 60B, 60C, 60D, and 60E, respectively. Hereinafter, the regions 60A to 60E may be collectively referred to as “region 60”. Similarly, the basic directions 62A to 62E may be collectively referred to as “basic direction 62”.
　第２実施形態に係るゲーム装置１０では、上記のような基本方向６２を示す基本方向データが記憶部１２に記憶される。図１４は基本方向データの一例を示す。図１４に示す基本方向データは、「領域ＩＤ」、「領域情報」、及び「基本方向情報」フィールドを含んでいる。「領域ＩＤ」フィールドには、領域６０を一意に識別する識別情報が格納される。「領域情報」フィールドには、領域６０を示す情報、すなわち領域６０に含まれる位置座標を特定するための情報が格納される。「基本方向情報」フィールドには、基本方向６２を示す情報（例えばベクトル情報）が格納される。 In the game apparatus 10 according to the second embodiment, the basic direction data indicating the basic direction 62 as described above is stored in the storage unit 12. FIG. 14 shows an example of basic direction data. The basic direction data shown in FIG. 14 includes “area ID”, “area information”, and “basic direction information” fields. In the “area ID” field, identification information for uniquely identifying the area 60 is stored. The “region information” field stores information indicating the region 60, that is, information for specifying position coordinates included in the region 60. In the “basic direction information” field, information indicating the basic direction 62 (for example, vector information) is stored.
　なお、第２実施形態に係るゲーム装置１０では、ある領域６０から次の領域６０にユーザキャラクタ３４が移動した場合に、ユーザキャラクタ３４の正面方向３４Ｆと基本方向６２とのずれが維持されるようになっている。同様に、視点の視線方向４２と基本方向６２とのずれも維持されるようになっている。 In the game device 10 according to the second embodiment, when the user character 34 moves from one region 60 to the next region 60, the deviation between the front direction 34F of the user character 34 and the basic direction 62 is maintained. It has become. Similarly, the deviation between the viewing direction 42 of the viewpoint and the basic direction 62 is also maintained.
　図１５は、ある領域から次の領域にユーザキャラクタ３４が移動した場合におけるユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の制御について説明するための図である。 FIG. 15 is a diagram for explaining the control of the front direction 34F and the visual line direction 42 of the user character 34 when the user character 34 moves from one area to the next area.
　ここでは、領域６０Ｂから領域６０Ｃにユーザキャラクタ３４が移動する場合を想定する。また、ここでは、領域６０Ｂから領域６０Ｃに移動する直前において、ユーザキャラクタ３４の正面方向３４Ｆは領域６０Ｂにおける基本方向６２Ｂから左回り（反時計回り）に角度Δθだけずれていることとする。なお、先述したように、視点の視線方向４２は、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように設定されるため、この場合、視点の視線方向４２も基本方向６２Ｂから左回り（反時計回り）に角度Δθだけずれていることになる。 Here, it is assumed that the user character 34 moves from the region 60B to the region 60C. Here, it is assumed that the front direction 34F of the user character 34 is shifted counterclockwise (counterclockwise) by the angle Δθ from the basic direction 62B in the region 60B immediately before moving from the region 60B to the region 60C. As described above, the viewpoint gaze direction 42 is set so that the XwZw plane component of the front direction 34F of the user character 34 and the XwZw plane component of the viewpoint gaze direction 42 indicate the same direction. In this case, the viewpoint line-of-sight direction 42 is also deviated by an angle Δθ counterclockwise (counterclockwise) from the basic direction 62B.
　この場合、ユーザキャラクタ３４が領域６０Ｂから領域６０Ｃに移動した時点において、ユーザキャラクタ３４の正面方向３４Ｆは、領域６０Ｃにおける基本方向６２Ｃから左回り（反時計回り）に角度Δθだけずれてなる方向に自動的に設定される。また、変更後のユーザキャラクタ３４の正面方向３４Ｆに合わせて、視点の視線方向４２も設定される（図５参照）。この結果、ユーザキャラクタ３４が領域６０Ｂから領域６０Ｃに移動した場合には、ユーザキャラクタ３４の正面方向３４Ｆと基本方向６２Ｂとのずれが維持されるようになっている。同様に、視点の視線方向４２と基本方向６２Ｂとのずれも維持されるようになっている。 In this case, when the user character 34 moves from the region 60B to the region 60C, the front direction 34F of the user character 34 is shifted in a direction that is shifted counterclockwise (counterclockwise) by the angle Δθ from the basic direction 62C in the region 60C. Set automatically. Further, the visual line direction 42 of the viewpoint is also set in accordance with the front direction 34F of the user character 34 after the change (see FIG. 5). As a result, when the user character 34 moves from the region 60B to the region 60C, the deviation between the front direction 34F of the user character 34 and the basic direction 62B is maintained. Similarly, the deviation between the viewing direction 42 of the viewpoint and the basic direction 62B is also maintained.
　第２実施形態に係るゲーム装置１０においても、第１実施形態と同様、ユーザはゲーム装置１０を傾けることによって、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を変更できるようになっている（図７，８参照）。 Also in the game device 10 according to the second embodiment, as in the first embodiment, the user can change the front direction 34F and the viewpoint line-of-sight direction 42 of the user character 34 by tilting the game device 10. (See FIGS. 7 and 8).
　また、第２実施形態に係るゲーム装置１０においても、第１実施形態と同様、ユーザはボタン１５Ｒ，１５Ｌを押下することによって、ユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２を比較的容易に大きく変更できるようになっている。 Also in the game apparatus 10 according to the second embodiment, similarly to the first embodiment, the user can relatively easily set the front direction 34F and the viewpoint line-of-sight direction 42 of the user character 34 by pressing the buttons 15R and 15L. It can be changed greatly.
　図１６は、ボタン１５Ｒが押下された場合のユーザキャラクタ３４の正面方向３４Ｆ及び視点の視線方向４２の変化の一例を示す。なお、図９，１０と同様、符号「３４ＦＡ」は変化前のユーザキャラクタ３４の正面方向３４Ｆを示し、符号「３４ＦＢ」は変化後のユーザキャラクタ３４の正面方向３４Ｆを示す。また、符号「４０Ａ」は変化前の視点の位置４０を示し、符号「４０Ｂ」は変化後の視点の位置４０を示す。同様に、符号「４２Ａ」は変化前の視点の視線方向４２を示し、符号「４２Ｂ」は変化後の視点の視線方向４２を示す。 FIG. 16 shows an example of changes in the front direction 34F and the visual line direction 42 of the user character 34 when the button 15R is pressed. As in FIGS. 9 and 10, the symbol “34FA” indicates the front direction 34F of the user character 34 before the change, and the symbol “34FB” indicates the front direction 34F of the user character 34 after the change. Reference numeral “40A” indicates the viewpoint position 40 before the change, and reference numeral “40B” indicates the viewpoint position 40 after the change. Similarly, the sign “42A” indicates the line-of-sight direction 42 of the viewpoint before the change, and the sign “42B” indicates the line-of-sight direction 42 of the viewpoint after the change.
　第２実施形態に係るゲーム装置１０では、仮想空間３０の領域ごとに複数の基本視線方向７０Ａ～７０Ｄが設定される。図１６に示す例の場合、基本視線方向７０Ａは基本方向６２と一致する方向である。基本視線方向７０Ｂは、基本方向６２を右回り（時計回り）に９０度回転することによって得られる方向である。また、基本視線方向７０Ｃは、基本方向６２を右回り（時計回り）に１８０度回転することによって得られる方向である。基本視線方向７０Ｄは、基本方向６２を右回り（時計回り）に２７０度回転することによって得られる方向である。なお以下では、基本視線方向７０Ａ～７０Ｄのことを総称して「基本視線方向７０」と記載する場合がある。 In the game apparatus 10 according to the second embodiment, a plurality of basic line-of-sight directions 70A to 70D are set for each region of the virtual space 30. In the case of the example shown in FIG. 16, the basic line-of-sight direction 70 </ b> A is a direction that matches the basic direction 62. The basic line-of-sight direction 70B is a direction obtained by rotating the basic direction 62 clockwise by 90 degrees (clockwise). The basic line-of-sight direction 70C is a direction obtained by rotating the basic direction 62 clockwise by 180 degrees (clockwise). The basic line-of-sight direction 70D is a direction obtained by rotating the basic direction 62 clockwise by 270 degrees. Hereinafter, the basic line-of-sight directions 70A to 70D may be collectively referred to as “basic line-of-sight direction 70”.
　第２実施形態に係るゲーム装置１０では、上記のような基本視線方向７０を示す基本視線方向データが記憶部１２に記憶される。図１７は基本視線方向データの一例を示す。図１７に示す基本視線方向データは、「領域ＩＤ」及び「基本視線方向情報」フィールドを含んでいる。「領域ＩＤ」フィールドには図１４と同様である。「基本視線方向情報」フィールドには、基本視線方向７０を示す情報（例えばベクトル情報）が格納される。 In the game apparatus 10 according to the second embodiment, the basic visual line direction data indicating the basic visual line direction 70 as described above is stored in the storage unit 12. FIG. 17 shows an example of basic line-of-sight direction data. The basic line-of-sight direction data shown in FIG. 17 includes “area ID” and “basic line-of-sight direction information” fields. The “area ID” field is the same as in FIG. In the “basic gaze direction information” field, information indicating the basic gaze direction 70 (for example, vector information) is stored.
　なお、図１６に示す例の場合、複数の基本視線方向７０Ａ～７０Ｄが基本方向６２に基づいて設定されているため、図１４に示す基本方向データに基づいて、複数の基本視線方向７０Ａ～７０Ｄを取得するようにしてもよい。この場合、図１７に示す基本視線方向データを省略するようにしてもよい。 In the case of the example shown in FIG. 16, since a plurality of basic viewing directions 70A to 70D are set based on the basic direction 62, a plurality of basic viewing directions 70A to 70D are based on the basic direction data shown in FIG. May be obtained. In this case, the basic gaze direction data shown in FIG. 17 may be omitted.
　図１６に示すように、ボタン１５Ｒが押下された場合には、視点の視線方向４２が複数の基本視線方向７０Ａ～７０Ｄのいずれかに変更される。具体的には、ボタン１５Ｒが押下された時点におけるユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＡ）を右回り（時計回り）に角度θｂ（９０度）回転してなる方向３４ＦＣが取得される。次に、基本視線方向７０Ａ～７０Ｄのうちで、上記方向３４ＦＣとの間の角度差が最も小さい基本視線方向７０が判断され、その基本視線方向７０がユーザキャラクタ３４の正面方向３４Ｆとして設定される。図１６に示す例の場合、上記方向３４ＦＣとの間の角度差が最も小さい基本視線方向７０が基本視線方向７０Ｂであるため、ユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）が基本視線方向７０Ｂに設定される。 As shown in FIG. 16, when the button 15R is pressed, the viewpoint line-of-sight direction 42 is changed to one of a plurality of basic line-of-sight directions 70A to 70D. Specifically, a direction 34FC obtained by rotating the front direction 34F (direction 34FA) of the user character 34 clockwise (clockwise) by an angle θb (90 degrees) when the button 15R is pressed is acquired. Next, among the basic line-of-sight directions 70A to 70D, the basic line-of-sight direction 70 having the smallest angle difference from the direction 34FC is determined, and the basic line-of-sight direction 70 is set as the front direction 34F of the user character 34. . In the example shown in FIG. 16, since the basic visual line direction 70 having the smallest angle difference from the direction 34FC is the basic visual line direction 70B, the front direction 34F (direction 34FB) of the user character 34 is changed to the basic visual line direction 70B. Is set.
　また、変更後のユーザキャラクタ３４の正面方向３４Ｆ（方向３４ＦＢ）に合わせて、視点の位置４０及び視線方向４２が設定される。カメラの位置４０及び視線方向４２は注視位置４４を維持しつつ変更される。具体的には、ユーザキャラクタ３４の正面方向３４ＦのＸｗＺｗ平面成分と、視点の視線方向４２のＸｗＺｗ平面成分とが同じ方向を示すように、視点の位置４０及び視線方向４２が設定される。その結果、視点の視線方向４２は、視点の視線方向４２のＸｗＺｗ平面成分と、基本視線方向７０Ｂとが同じ方向を示すように設定される。この場合、注視位置４４を中心として位置４０Ａを右回り（時計回り）に角度θｂ（９０度）だけ回転してなる位置４０Ｃから注視位置４４への方向４２Ｃとの間の角度差が基本視線方向７０Ａ～７０Ｄのうちで最も小さい基本視線方向７０Ｂが、視点の視線方向４２として設定されることになる。 Also, the viewpoint position 40 and the line-of-sight direction 42 are set in accordance with the front direction 34F (direction 34FB) of the user character 34 after the change. The camera position 40 and the line-of-sight direction 42 are changed while maintaining the gaze position 44. Specifically, the viewpoint position 40 and the line-of-sight direction 42 are set so that the XwZw plane component in the front direction 34F of the user character 34 and the XwZw plane component in the viewpoint line-of-sight direction 42 indicate the same direction. As a result, the viewpoint line-of-sight direction 42 is set so that the XwZw plane component of the viewpoint line-of-sight direction 42 and the basic line-of-sight direction 70B indicate the same direction. In this case, the angle difference between the direction 40C from the position 40C obtained by rotating the position 40A clockwise (clockwise) by the angle θb (90 degrees) about the gaze position 44 and the direction 42C from the gaze position 44 is the basic gaze direction. The smallest basic viewing direction 70B among 70A to 70D is set as the viewing direction 42 of the viewpoint.
　図１６ではボタン１５Ｒが押下された場合について説明したが、ボタン１５Ｌが押下された場合も同様にして、ユーザキャラクタ３４の正面方向３４Ｆと視点の位置４０及び視線方向４２とが設定されることになる。 Although the case where the button 15R is pressed has been described with reference to FIG. 16, the front direction 34F, the viewpoint position 40, and the line-of-sight direction 42 of the user character 34 are set in the same manner when the button 15L is pressed. Become.
　以上に説明した第２実施形態に係るゲーム装置１０では、ボタン１５Ｒ，１５Ｌが押下された場合の視点の視線方向４２として、ユーザキャラクタ３４が位置している仮想空間３０の領域６０に適した方向が設定されるようになる。例えば、ボタン１５Ｒ，１５Ｌが押下された場合の視点の視線方向４２が、仮想空間３０の領域６０におけるユーザキャラクタ３４の基本的な進行方向を考慮して設定されるようになる。 In the game apparatus 10 according to the second embodiment described above, the direction suitable for the region 60 of the virtual space 30 in which the user character 34 is located as the visual line direction 42 of the viewpoint when the buttons 15R and 15L are pressed. Will be set. For example, the visual line direction 42 of the viewpoint when the buttons 15R and 15L are pressed is set in consideration of the basic traveling direction of the user character 34 in the region 60 of the virtual space 30.
　なお、図１６に示す例では、四つの方向が基本視線方向７０として設定されるようになっていたが、四つより多くの数の方向や四つ未満の数の方向が基本視線方向７０として設定されるようにしてもよい。例えば、八つの方向が基本視線方向７０として設定されるようにしてもよい。すなわち、４５度ごとに異なる方向が基本視線方向７０として設定されるようにしてもよい。また例えば、三つの方向が基本視線方向７０として設定されるようにしてもよい。すなわち、１２０度ごとに異なる方向が基本視線方向７０として設定されるようにしてもよい。 In the example shown in FIG. 16, four directions are set as the basic line-of-sight directions 70, but more than four directions or less than four directions are set as the basic line-of-sight directions 70. It may be set. For example, eight directions may be set as the basic viewing direction 70. That is, a different direction every 45 degrees may be set as the basic line-of-sight direction 70. For example, three directions may be set as the basic line-of-sight direction 70. That is, a different direction every 120 degrees may be set as the basic line-of-sight direction 70.
　また、図１６に示す例では、基本視線方向７０が基本方向６２に基づいて設定されるようになっていたが、基本視線方向７０は基本方向６２とは関係なく設定されるようにしてもよい。 In the example shown in FIG. 16, the basic line-of-sight direction 70 is set based on the basic direction 62, but the basic line-of-sight direction 70 may be set regardless of the basic direction 62. .
　また、図１６に示す例では、基本視線方向７０が仮想空間３０の領域６０ごとに設定されることとして説明したが、仮想空間３０のいずれの領域６０においても同じ基本視線方向７０が設定されるようにしてもよい。例えば、Ｘｗ軸正方向、Ｘｗ軸負方向、Ｚｗ軸正方向、及びＺｗ軸負方向のような仮想空間３０における固定方向が基本視線方向７０として設定されるようにしてもよい。 In the example illustrated in FIG. 16, the basic line-of-sight direction 70 has been described as being set for each area 60 of the virtual space 30, but the same basic line-of-sight direction 70 is set in any area 60 of the virtual space 30. You may do it. For example, a fixed direction in the virtual space 30 such as the Xw-axis positive direction, the Xw-axis negative direction, the Zw-axis positive direction, and the Zw-axis negative direction may be set as the basic line-of-sight direction 70.
　なお、本発明は以上に説明した第１実施形態及び第２実施形態に限定されるものではない。 Note that the present invention is not limited to the first and second embodiments described above.
　［１］以上に説明した第１実施形態及び第２実施形態では、図９，１０，１６における角度θｂが一定（９０度）であることとして説明したが、角度θｂは一定でなくてもよい。 [1] In the first and second embodiments described above, the angle θb in FIGS. 9, 10, and 16 has been described as being constant (90 degrees), but the angle θb may not be constant. .
　［１－１］例えば、ユーザがユーザキャラクタ３４（操作対象）を複数のゲームキャラクタ（複数の操作対象候補）のうちから選択できるようになっているような場合には、ユーザキャラクタ３４として選択されたゲームキャラクタによって、上記角度θｂが異なるようにしてもよい。 [1-1] For example, when the user can select the user character 34 (operation target) from among a plurality of game characters (a plurality of operation target candidates), the user character 34 is selected. The angle θb may be different depending on the game character.
　この場合、例えば図１８に示すような角度データが記憶部１２に記憶される。図１８に示す角度データでは複数のゲームキャラクタの各々に上記角度θｂが対応づけられている。なお図１８において、「θ１」、「θ２」、及び「θ３」は、それぞれ、所定の角度を示している。図１８に示す角度データによれば、例えば、ゲームキャラクタ１がユーザキャラクタ３４として選択された場合には角度θｂが角度θ１に設定される。 In this case, for example, angle data as shown in FIG. 18 is stored in the storage unit 12. In the angle data shown in FIG. 18, the angle θb is associated with each of a plurality of game characters. In FIG. 18, “θ1”, “θ2”, and “θ3” each indicate a predetermined angle. According to the angle data shown in FIG. 18, for example, when the game character 1 is selected as the user character 34, the angle θb is set to the angle θ1.
　このようにすれば、ユーザキャラクタ３４として選択されたゲームキャラクタによって、視点の視線方向４２の変化の仕方（すなわち、視点の視野の変化の仕方）を変えることができるようになる。 In this way, the way of changing the visual line direction 42 of the viewpoint (that is, the way of changing the visual field of the viewpoint) can be changed by the game character selected as the user character 34.
　［１－２］また例えば、ユーザキャラクタ３４の能力に関するパラメータ（例えば、視野の広さを示すパラメータ）によって、上記角度θｂが異なるようにしてもよい。 [1-2] Further, for example, the angle θb may be different depending on a parameter relating to the ability of the user character 34 (for example, a parameter indicating the width of the field of view).
　この場合、例えば図１９に示すような角度データが記憶部１２に記憶される。図１９に示す角度データでは能力パラメータの範囲に上記角度θｂが対応づけられている。なお、図１９において、「Ｐ１」及び「Ｐ２」はそれぞれ所定の値を示している。また、図１８と同様、「θ１」、「θ２」、及び「θ３」はそれぞれ所定の角度を示している。 In this case, for example, angle data as shown in FIG. 19 is stored in the storage unit 12. In the angle data shown in FIG. 19, the angle θb is associated with the capability parameter range. In FIG. 19, “P1” and “P2” each indicate a predetermined value. Similarly to FIG. 18, “θ1”, “θ2”, and “θ3” each indicate a predetermined angle.
　この場合、ユーザキャラクタ３４の能力パラメータの値（ｐ）が属する範囲に対応づけられた角度が上記角度θｂとして用いられる。例えば、ユーザキャラクタ３４の能力パラメータの値（ｐ）が「Ｐ１≦ｐ＜Ｐ２」を満足する場合には上記角度θｂが角度θ２に設定される。 In this case, an angle associated with a range to which the value (p) of the ability parameter of the user character 34 belongs is used as the angle θb. For example, when the ability parameter value (p) of the user character 34 satisfies “P1 ≦ p <P2”, the angle θb is set to the angle θ2.
　このようにすれば、ユーザキャラクタ３４のパラメータの値によって、視点の視線方向４２の変化の仕方（すなわち、視点の視野の変化の仕方）を変えることができるようになる。 In this way, the way of changing the visual line direction 42 of the viewpoint (that is, the way of changing the visual field of the viewpoint) can be changed according to the parameter value of the user character 34.
　［２］第２の視線方向制御部５４によって視点の視線方向４２が所定方向に設定された場合における視点の視野に床３２Ａや壁３２Ｂしか含まれず、敵キャラクタ３６が含まれていない場合には、床３２Ａや壁３２Ｂのみがゲーム画面に表示されるようになる。このような状態はユーザにとってあまり意味がない。このため、下記に説明するようにしてもよい。 [2] When the viewpoint line-of-sight direction 42 is set to a predetermined direction by the second line-of-sight direction control unit 54, the viewpoint field of view includes only the floor 32A and the wall 32B and does not include the enemy character 36. Only the floor 32A and the wall 32B are displayed on the game screen. Such a state does not make much sense to the user. For this reason, you may make it demonstrate below.
　ゲーム装置１０は、第２の視線方向制御部５４によって視点の視線方向４２が所定方向に設定された場合における視点の視野に、所定のオブジェクトが存在しているか否かを判定する。ここで、「所定のオブジェクト」とは、ユーザにとって重要性の高いオブジェクト（言い換えれば、ゲーム画面に表示される必要性がユーザにとって高いオブジェクト）である。図４に示す仮想空間３０の場合、敵キャラクタ３６が「所定のオブジェクト」に相当する。 The game apparatus 10 determines whether or not a predetermined object is present in the visual field of the viewpoint when the visual line direction 42 of the visual point is set to the predetermined direction by the second visual line direction control unit 54. Here, the “predetermined object” is an object that is highly important for the user (in other words, an object that is highly necessary for the user to be displayed on the game screen). In the case of the virtual space 30 shown in FIG. 4, the enemy character 36 corresponds to a “predetermined object”.
　そして、視点の視線方向４２が所定方向に設定された場合における視点の視野に所定のオブジェクトが存在しない場合、第２の視線方向制御部５４は、ボタン１５Ｒ，１５Ｌが押下された時点における視点の視線方向４２と上記所定方向との間の角度差よりも、ボタン１５Ｒ，１５Ｌが押下された時点における視点の視線方向４２との間の角度差が大きくなるような方向を、視点の視線方向４２として設定する。例えば、第２の視線方向制御部５４は、視点の視野に敵キャラクタ３６が含まれるようになるまで、上記角度θｂを初期値（９０度）から所定角度（例えば４５度又は９０度）ずつ大きくしていく。そして、第２の視線方向制御部５４は、視点の視野に敵キャラクタ３６が含まれるようになった場合の視線方向４２を、視点の視線方向４２として設定する。 If the predetermined object does not exist in the visual field of the viewpoint when the visual line direction 42 of the viewpoint is set to the predetermined direction, the second visual line direction control unit 54 determines the viewpoint at the time when the buttons 15R and 15L are pressed. A direction in which the angle difference between the visual line direction 42 of the viewpoint when the buttons 15R and 15L are pressed is larger than the angular difference between the visual line direction 42 and the predetermined direction is a visual line direction 42 of the visual point. Set as. For example, the second gaze direction control unit 54 increases the angle θb from the initial value (90 degrees) by a predetermined angle (for example, 45 degrees or 90 degrees) until the enemy character 36 is included in the visual field of the viewpoint. I will do it. Then, the second line-of-sight direction control unit 54 sets the line-of-sight direction 42 when the enemy character 36 is included in the visual field of the viewpoint as the visual line-of-sight direction 42 of the viewpoint.
　このようにすれば、ボタン１５Ｒ，１５Ｌが押下された場合に敵キャラクタ３６がゲーム画面に表示されるように担保されるようになる。 In this way, when the buttons 15R and 15L are pressed, the enemy character 36 is secured to be displayed on the game screen.
　［３］以上に説明した第１実施形態及び第２実施形態では、視点がユーザキャラクタ３４の背後の上方に設定されるようになっていたが、視点はユーザキャラクタ３４の頭部内の位置（例えば、左目と右目との間の中間位置）に設定されるようにしてもよい。この場合、視点の視線方向４２はユーザキャラクタ３４の正面方向３４Ｆと略等しくなり、視点の視野はユーザキャラクタ３４の視野と略等しくなる。このため、図７（Ｂ）、図８（Ｂ）、図９、図１０、図１６において、視点の視線方向４２はユーザキャラクタ３４の正面方向３４Ｆと同様に変化することになる。 [3] In the first embodiment and the second embodiment described above, the viewpoint is set above the back of the user character 34, but the viewpoint is a position in the head of the user character 34 ( For example, it may be set to an intermediate position between the left eye and the right eye. In this case, the visual line direction 42 of the viewpoint is substantially equal to the front direction 34F of the user character 34, and the visual field of the viewpoint is substantially equal to the visual field of the user character 34. For this reason, in FIG. 7B, FIG. 8B, FIG. 9, FIG. 10, and FIG. 16, the visual line direction 42 of the viewpoint changes in the same manner as the front direction 34F of the user character 34.
　[４]以上に説明した第１実施形態及び第２実施形態では、視線方向４２を仮想空間３０に対してＸ軸方向へ変化させるような例について説明したが、視線方向４２を仮想空間３０に対して異なる軸方向(例えばＹ軸方向)へ変化させるようにしてもよい。つまり、以上に説明した第１実施形態及び第２実施形態では、視線方向４２を左右に変化させるような視線方向制御がなされているが、視線方向４２を上下に変化させるような視線方向制御がなされるようにしてもよい。 [4] In the first embodiment and the second embodiment described above, an example in which the line-of-sight direction 42 is changed in the X-axis direction with respect to the virtual space 30 has been described, but the line-of-sight direction 42 is changed to the virtual space 30. On the other hand, you may make it change to a different axial direction (for example, Y-axis direction). That is, in the first embodiment and the second embodiment described above, the gaze direction control is performed such that the gaze direction 42 is changed to the left and right, but the gaze direction control is performed such that the gaze direction 42 is changed up and down. It may be made.
　［５］例えば、本発明は、ゲーム装置１０と、ゲーム装置１０と通信可能な制御装置（例えばサーバ装置）と、を含むゲームシステムに適用することも可能である。例えば、このゲームシステムでは、ユーザが操作部１５を用いて行った操作に関する操作情報と、動き検出部１６の検出結果に関する検出結果情報と、がゲーム装置１０から制御装置に送信される。制御装置では、ゲーム装置１０の表示部１８に表示されるゲーム画面を更新するために用いられるデータ（例えば、ゲーム画面データ又はゲーム状況データ等）が、ゲーム装置１０から受信された操作情報及び／又は検出結果情報に基づいて生成され、該データがゲーム装置１０に送信される。そして、ゲーム装置１０では、制御装置から受信された上記のデータに基づいて、ゲーム画面が表示部１８に表示される。 [5] For example, the present invention can also be applied to a game system including the game device 10 and a control device (for example, a server device) that can communicate with the game device 10. For example, in this game system, operation information related to an operation performed by the user using the operation unit 15 and detection result information related to a detection result of the motion detection unit 16 are transmitted from the game device 10 to the control device. In the control device, data used for updating the game screen displayed on the display unit 18 of the game device 10 (for example, game screen data or game situation data) is received from the operation information received from the game device 10 and / or Alternatively, it is generated based on the detection result information, and the data is transmitted to the game apparatus 10. In the game apparatus 10, the game screen is displayed on the display unit 18 based on the above data received from the control apparatus.
　この場合、第１の視線方向制御部５２及び第２の視線方向制御部５４は制御装置において実現されるようにしてもよい。すなわち、制御装置（例えばサーバ装置）の制御部がプログラムを実行することによって、当該制御部が第１の視線方向制御部５２及び第２の視線方向制御部５４として機能するようにしてもよい。なお、この場合、第１の視線方向制御部５２又は第２の視線方向制御部５４によって更新された視線方向に基づいて生成されたゲーム画面データが制御装置からゲーム装置１０に送信されるようにしてもよい。あるいは、第１の視線方向制御部５２又は第２の視線方向制御部５４によって更新された視線方向を示すデータ（ゲーム状況データ）が制御装置からゲーム装置１０に送信されるようにし、このデータに基づいて、ゲーム画面がゲーム装置１０において生成されるようにしてもよい。また、この場合、第１の視線方向制御部５２又は第２の視線方向制御部５４の視線方向制御のために必要なデータは、制御装置の記憶部、又は制御装置からアクセス可能な記憶装置に記憶しておくようにすればよい。 In this case, the first line-of-sight direction control unit 52 and the second line-of-sight direction control unit 54 may be realized in the control device. That is, the control unit of the control device (for example, the server device) may execute the program so that the control unit functions as the first gaze direction control unit 52 and the second gaze direction control unit 54. In this case, game screen data generated based on the gaze direction updated by the first gaze direction control unit 52 or the second gaze direction control unit 54 is transmitted from the control device to the game device 10. May be. Alternatively, data (game situation data) indicating the line-of-sight direction updated by the first line-of-sight direction control unit 52 or the second line-of-sight direction control unit 54 is transmitted from the control device to the game apparatus 10, and Based on this, a game screen may be generated in the game apparatus 10. In this case, the data necessary for the gaze direction control of the first gaze direction control unit 52 or the second gaze direction control unit 54 is stored in the storage unit of the control device or the storage device accessible from the control device. Just remember it.
　［６］以上では、ユーザキャラクタ３４が敵キャラクタ３６を退治するゲームに本発明を適用する場合について主に説明したが、本発明はこのようなゲーム以外のゲームにも適用することができる。本発明は、視点から見た仮想空間３０を表すゲーム画面が表示されるようなゲームに適用することが可能である。 [6] Although the case where the present invention is applied to a game in which the user character 34 defeats the enemy character 36 has been mainly described above, the present invention can also be applied to a game other than such a game. The present invention can be applied to a game in which a game screen representing the virtual space 30 viewed from the viewpoint is displayed.
