Parent Constraint
Parent Constraint は、任意のゲームオブジェクトがあたかも Hierarchy ウィンドウの他のゲームオブジェクトの子であるかのように、ゲームオブジェクトを移動し回転させます。ただし、あるゲームオブジェクトをもう 1 つのゲームオブジェクトの親にする場合には不可能な、以下のような利点があります。
Parent Constraint はスケールには影響しません。
1 つの Parent Constraint を、複数のゲームオブジェクトに関連付けることができます。
任意のゲームオブジェクトは、Parent Constraint が関連付けられたゲームオブジェクトの子である必要はありません。
Weight (ウェイト) を指定して、コンストレイントの効果を変えることができます。また、各ソースゲームオブジェクトのウェイトも指定できます。
例えば、剣をキャラクターの手の中に置くには、Parent Constraint コンポーネントを剣のゲームオブジェクトに追加します。Parent Constraint の Sources リストで、キャラクターの手に紐づけます。このようにして、剣の動きは手の位置と回転にコンストレインされます。
プロパティ
| Property: | Function: | |
|---|---|---|
| Activate | After you move and rotate the constrained GameObject and its source GameObjects, click Activate to save this information. Activate saves the current offset from the source GameObjects in Rotation At Rest, Position At Rest, Position Offset, and Rotation Offset, then checks Is Active and Lock. | |
| Zero | Sets the position and rotation of the constrained GameObject to the source GameObjects. Zero resets the Rotation At Rest, Position At Rest, Position Offset, 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 move and rotate this GameObject at the same rate as its source GameObjects. 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. | |
| Constraint Settings | ||
| Lock | Toggle to let the Constraint move and rotate the GameObject. Uncheck this property to edit the position and rotation of this GameObject. You can also edit the Rotation At Rest, Position At Rest, Position Offset, and Rotation Offset properties. If Is Active is checked, the Constraint updates the Rotation At Rest, Position At Rest, Position Offset, or Rotation Offset properties for you as you move and rotate the GameObject or its Source GameObjects. When you are satisfied with your changes, check Lock to let the Constraint to control this GameObject. This property has no effect in Play Mode. | |
| Position At Rest | The X, Y, and Z values to use when Weight is 0 or when the corresponding Freeze Position Axes are not checked. To edit these fields, uncheck Lock. | |
| 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. | |
| Position Offset | The X, Y, and Z position offset from the Transform that the Constraint imposes. To edit these fields, uncheck Lock. | |
| Rotation Offset | The X, Y, and Z rotation offset from the Transform that the Constraint imposes. To edit these fields, uncheck Lock. | |
| Freeze Position Axes | Check X, Y, or Z to allow the Constraint to control the corresponding position axes. Uncheck an axis to stop the Constraint from controlling it, which allows you to edit, animate, or script it. | |
| Freeze Rotation Axes | Check X, Y, or Z to allow the Constraint to control the corresponding rotation axes. Uncheck an axis to stop the Constraint from controlling it, which allows you to edit, animate, or script it. | |
| Sources | The list of GameObjects that constrain this GameObject. Unity evaluates source GameObjects in the order they appear in this list. This order affects how this Constraint moves and 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. | |
