Debug.DrawLine from custom inspector

Questions & Answers
1

I’m making a custom inspector for a monobehaviour, and i wish to call Debug.DrawLine into the sceneview while the inspector is active.
I’ve read that you have to call it from sceneview update, not from OnInspectorGUI or anywhere else. What would be the proper way of doing that?

public override void OnInspectorGUI()
{
    obstacle = (Obstacle)target;
    
    bool isPrefab = PrefabUtility.GetPrefabType(obstacle) == PrefabType.Prefab ? true : false;

    obstacle.UpdateTransform();

    obstacle.Center = EditorGUILayout.Vector2Field("Offset", obstacle.Center);
    obstacle.Radius = EditorGUILayout.FloatField("Radius", obstacle.Radius);

    if (!isPrefab && SceneView.lastActiveSceneView != null)
    {
        //    Draw the obstacle using Debug.DrawLine()
        obstacle.DrawBoundingBall(Color.red);
    }
}

If anyone else is also searching for this, i found my way around it using OnDrawGizmos() on the actual monobehaviour, and not on the custo inspector.
Trying to draw from the custom inspector was a complete failure for me.
