Handles.Disc

파라미터

반환

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.

설명

Make a 3D disc that can be dragged with the mouse. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

Disc Handle on the Scene View.

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

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

        EditorGUI.BeginChangeCheck();
        Quaternion rot = Handles.Disc(t.rot, t.transform.position, new Vector3(1, 1, 0), 5, false, 1);

        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Disc Rotate");
            t.rot = rot;
            t.Update();
        }
    }
}

And the script attached to this Handle:

// Name this script "DiscHandle"
using UnityEngine;
[ExecuteInEditMode]
public class DiscHandle : MonoBehaviour
{
    public Quaternion rot = Quaternion.identity;
    public void Update()
    {
        transform.rotation = rot;
    }
}
