Handles.RotationHandle

Parámetros

Valor de retorno

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

Descripción

Make a Scene view rotation handle.

This behaves like the built-in Rotation tool in Unity. If you have assigned something to Undo.SetSnapshotTarget, it works fully with Undo.


Rotate the attached object from the Rotation Handle.

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

// Name this script "RotateAtPointEditor"
using UnityEngine;
using UnityEditor;

[CustomEditor(typeof(RotateAtPoint))]
[CanEditMultipleObjects]
public class RotateAtPointEditor : Editor
{
    public void OnSceneGUI()
    {
        RotateAtPoint t = (target as RotateAtPoint);

        EditorGUI.BeginChangeCheck();
        Quaternion rot = Handles.RotationHandle(t.rot, Vector3.zero);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Rotated RotateAt Point");
            t.rot = rot;
            t.Update();
        }
    }
}

And attach this script to the GameObject:

// Name this script "RotateAtPoint"
using UnityEngine;

[ExecuteInEditMode]
public class RotateAtPoint : MonoBehaviour
{
    public Quaternion rot = Quaternion.identity;
    public void Update()
    {
        transform.rotation = rot;
    }
}
