// 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();
        }
    }
