using System.Collections.Generic;
using UnityEngine;
using UnityEditor;

[CustomEditor(typeof(SolidRectangleExample))]
public class DrawSolidRectangle : Editor
{
    void OnSceneGUI()
    {
        SolidRectangleExample t = target as SolidRectangleExample;
        Vector3 pos = t.transform.position;

        Vector3[] verts = new Vector3[] {
            new Vector3(pos.x - t.range, pos.y, pos.z - t.range),
            new Vector3(pos.x - t.range, pos.y, pos.z + t.range),
            new Vector3(pos.x + t.range, pos.y, pos.z + t.range),
            new Vector3(pos.x + t.range, pos.y, pos.z - t.range)
        };

        Handles.DrawSolidRectangleWithOutline(verts, new Color(0.5f, 0.5f, 0.5f, 0.1f), new Color(0, 0, 0, 1));

        foreach (Vector3 posCube in verts)
        {
            t.range = Handles.ScaleValueHandle(t.range,
                    posCube,
                    Quaternion.identity,
                    1.0f,
                    Handles.CubeHandleCap,
                    1.0f);
        }
    }
}
