OnDrawGizmos()

Gizmos can be drawn inside an OnDrawGizmos method, which is automatically invoked by the Unity editor. An alternative method is OnDrawGizmosSelected, which is only invoked for selected objects.

Gizmos are drawn directly in world space, not in the object’s local space.

OnDrawGizmos methods are also invoked while Unity is in edit mode.

	private void OnDrawGizmos () {
		if (vertices == null) {
			return;
		}
		Gizmos.color = Color.black;
		for (int i = 0; i < vertices.Length; i++) {
			Gizmos.DrawSphere(transform.TransformPoint(vertices[i]), 0.1f);
			// gizmos will move with the object
		}
	}
