id Control id of the handle.
rotation ハンドルの向き
position 3D 空間でのハンドルの中心
size ハンドルのサイズ

注意: 画面サイズに対して固定サイズのハンドルを持ちたい場合、 HandleUtility.GetHandleSize を使用します。


Quaternion ユーザーのハンドル操作によって更新された回転値。ユーザーがハンドルを操作しない場合は、関数に渡した値と同じ値が返されます。



The handle can rotate freely on all axes. The rotation gizmo has no visible axes and is simply a circle in the Scene view. Users can click and drag from within the circle to provide input rotation to your editor script.

FreeRotate handle seen in the Scene View.
