Why do Unity not showing Gizmos?
I have copied code from this tutorial .But problem is no gizmo is showing for waypoint. What wrong is creating this problem?

I also write this GizmoDraw.cs to see gizmos in runtime which works fine
using UnityEngine;
using System.Collections.Generic;
using System.Collections;
public class GizmoDraw : MonoBehaviour
{
public List<Waypoint> waypoints;
void Awake()
{
int count = transform.childCount;
for(int i =0; i<count; i++)
{
waypoints.Add(transform.GetChild(i).GetComponent<Waypoint>());
}
}
void Update()
{
Debug.Log("Total " + waypoints.Count);
}
void OnDrawGizmos()
{
// Draw a yellow sphere at the transform's position
/*Gizmos.color = Color.yellow;
Gizmos.DrawSphere(transform.position, 1);
*/
Gizmos.color = Color.yellow ;
foreach(Waypoint waypoint in waypoints)
{
Gizmos.DrawSphere(waypoint.transform.position, 0.1f);
Gizmos.color = Color.white;
Gizmos.DrawLine(waypoint.transform.position + (waypoint.transform.right * waypoint.width / 2f),
waypoint.transform.position - (waypoint.transform.right *waypoint.width / 2f));
if(waypoint.previousWaypoint != null)
{
Gizmos.color = Color.red;
Vector3 offset = waypoint.transform.right * waypoint.width / 2f;
Vector3 offsetTo = waypoint.previousWaypoint.transform.right * waypoint.previousWaypoint.width / 2f;
Gizmos.DrawLine(waypoint.transform.position + offset,waypoint.previousWaypoint.transform.position + offsetTo );
}
if(waypoint.nextWaypoint != null)
{
Gizmos.color = Color.green;
Vector3 offset = waypoint.transform.right * -waypoint.width / 2f;
Vector3 offsetTo = waypoint.nextWaypoint.transform.right * -waypoint.width / 2f;
Gizmos.DrawLine(waypoint.transform.position + offset, waypoint.nextWaypoint.transform.position + offsetTo );
}
if(waypoint.branches != null)
{
foreach(Waypoint branch in waypoint.branches)
{
Gizmos.color = Color.blue;
Gizmos.DrawLine(waypoint.transform.position, branch.transform.position);
}
}
}
}
}
It will be helpful for any suggestion.
