Handles.FreeRotateHandle

Parameters

Returns

Quaternion The new rotation value modified by the user's interaction with the handle. If the user has not moved the handle, it will return the same value as you passed into the function.

Description

Make an unconstrained rotation handle.

This 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.

Note: Use HandleUtility.GetHandleSize if you want the handle to always remain the same size on the screen.
