Aim Constraint

Aim Constraint はゲームオブジェクトは元となる (ソース) ゲームオブジェクトの方向に回転させます。

Aim Constraint はソースオブジェクトに合わせてゲームオブジェクトを回転させるのと同時に、もう 1 つの軸の向きを一定に維持することができます。例えば、カメラに Aim Constraint を追加します。Constraint が適用されているときにカメラを直立に保つには、カメラのアップ (上を指す) 軸とそれに沿ったアップ方向を指定します。

Up Vector を使用して、コンストレイントされたゲームオブジェクトのアップ軸を指定します。上方向を指定するには World Up Vector を使用します。Aim Constraint によってゲームオブジェクトをソースゲームオブジェクトを向くように回転させ、また、コンストレイントされたゲームオブジェクトのアップ軸を上に向けます。

プロパティー

Property: Function:
Activate After you rotate the constrained GameObject and move its source GameObjects, click Activate to save this information. Activate saves the current offset from the source GameObjects in Rotation At Rest and Rotation Offset, then checks Is Active and Lock.
Zero Sets the rotation of the constrained GameObject to the source GameObjects. Zero resets the Rotation At Rest and Rotation Offset fields, then checks Is Active and Lock.
Is Active Toggles whether or not to evaluate the Constraint. To also apply the Constraint, make sure Lock is checked.
Weight The strength of the Constraint. A weight of 1 causes the Constraint to rotate this GameObject at the same rate that its source GameObjects move. A weight of 0 removes the effect of the Constraint completely. This weight affects all source GameObjects. Each GameObject in the Sources list also has a weight.
Aim Vector Specifies the axis which faces the direction of its source GameObjects. For example, to specify that the GameObject should orient only its positive Z axis to face the source GameObjects, enter an Aim Vector of 0, 0, 1 for the X, Y, and Z axes, respectively.
Up Vector Specifies the up axis of this GameObject. For example, to specify that the GameObject should always keep its positive Y axis pointing upward, enter an Up Vector of 0, 1, 0 for the X, Y, and Z axes, respectively.
World Up Type Specifies the axis for the upward direction. The Aim Constraint uses this vector to align the up axis of the GameObject the upward direction.
Scene Up The Y axis of the scene.
Object Up The Y axis of the GameObject referred to by World Up Object.
Object Up Rotation The axis specified by World Up Vector of the GameObject referred to by World Up Object.
Vector The World Up Vector.
None Do not use a World Up vector.
World Up Vector Specifies the vector to use for the Object Up Rotation and Vector choices in World Up Type.
World Up Object Specifies the GameObject to use for the Object Up and Object Up Rotation choices in World Up Type.
Constraint Settings  
Lock Toggle to let the Constraint rotate the GameObject. Uncheck this property to edit the rotation of this GameObject. You can also edit the Rotation At Rest and Rotation Offset properties. If Is Active is checked, the Constraint updates the Rotation At Rest or Rotation Offset properties for you as you rotate the GameObject or its source GameObjects. When you are satisfied with your changes, check Lock to let the Constraint control this GameObject. This property has no effect in Play Mode.
Rotation At Rest The X, Y, and Z values to use when Weight is 0 or when the corresponding Freeze Rotation Axes are not checked. To edit these fields, uncheck Lock.
Rotation Offset The X, Y, and Z offset from the rotation that is calculated by the Constraint. To edit these fields, uncheck Lock.
Freeze Rotation Axes Check X, Y, or Z to allow the Constraint to control the corresponding axes. Uncheck an axis to stop the Constraint from controlling it. This allows you to edit, animate, or script the unfrozen axis.
Sources The list of GameObjects that constrain this GameObject. Unity evaluates source GameObjects in the order that they appear in this list. This order affects how this Constraint rotates the constrained GameObject. To get the result you want, drag and drop items in this list. Each source has a weight from 0 to 1.
