Handles.RotationHandle

Parameters

Returns

Quaternion 通过用户与手柄的交互修改的新旋转值。如果用户没有移动手柄，则将返回您传递给相应函数的值。

Description

创建一个场景视图旋转手柄。

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();
        }
    }
}

附加到此游戏对象的脚本：

// Name this script "RotateAtPoint"
using UnityEngine;

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