Handles.RotationHandle

パラメーター

戻り値

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。

説明

シーンビューの Rotation ハンドルを作ります。

This will behave like the built-in rotation tool in Unity. If you have assigned something to Undo.SetSnapshotTarget, it will work fully with Undo. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.


Rotate the attached object from the Rotation Handle.

// 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 the script attached to this GameObject:

// Name this script "RotateAtPoint"
using UnityEngine;

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