설명

Make a 3D slider.

This draws a 3D draggable handle on the screen. The handle is constrained to sliding along a direction vector in 3D space.
Slider handle in the Scene view.

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

// Name this script "SliderHandleEditor"
using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(SliderHandle))]
public class SliderHandleEditor : Editor
{

    // Simple script that creates a Slide Handle that 
    // allows you to drag a 'look at' point along the X axis

    void OnSceneGUI()
    {

        SliderLook t = (target as SliderLook);
        EditorGUI.BeginChangeCheck();
        Vector3 lookTarget = Handles.Slider(t.lookTarget, new Vector3(1, 0, 0), 2, Handles.ConeCap, 0.1f);
        if (EditorGUI.EndChangeCheck())
        {
            Undo.RecordObject(target, "Changed Slider Look Target");
            t.lookTarget = lookTarget;
            t.Update();
        }
    }

}

And the script attached to this Handle:

// Name this script "SliderHandle"
using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class SliderHandle : MonoBehaviour
{
	public Vector3 lookTarget = new Vector3(0,0,0);
	
	public void Update() {
        transform.LookAt(lookTarget);
	}

}
