public void OnDrawGizmos()

Remarks

Allows you to quickly pick important objects in your Scene. When you select a child GameObject's gizmo, it selects the parent GameObject. this is because pickability is based on the callback’s host GameObject, not the transform used for drawing. To make a child GameObject’s gizmo directly selectable, implement
OnDrawGizmos
or
OnDrawGizmosSelected
on the child GameObject’s component.
OnDrawGizmos
uses a mouse position that is relative to the Scene View. Note: If Auto-hide gizmos is enabled in the Scene View preferences, then
OnDrawGizmos
is not called on components that are collapsed in the Inspector. Use MonoBehaviour.OnDrawGizmosSelected() to draw gizmos when the GameObject is selected.
using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour{ void OnDrawGizmos() { // Draw a yellow sphere at the transform's position Gizmos.color = Color.yellow; Gizmos.DrawSphere(transform.position, 1); }}
