OnDrawGizmos not showing up in Scene view

Hi Guys,

I’m relatively new to this. So I have an empty game object in my scene called “Position”. It has only a transform on it.

I wrote a script called ‘Position’ and dragged it onto the object so that I can have a Gizmo drawn onto it in the Scene View. Whatever I do - the Gizmos don’t show up. I have all the boxes in the drop down Gizmos display ticked. What have I done wrong?

using UnityEngine;
using System.Collections;

public class Position : MonoBehaviour {
    public float explosionRadius = 5.0F;

    void onDrawGizmos() {
        // Gizmos.color = Color.white;
        Gizmos.DrawWireSphere(transform.position, explosionRadius);
        Debug.Log("I am working");
    }
    
}

onDrawGizmos with capital “O” => OnDrawGizmos
