There is a really neat way that you can turn on and off all your assistant testing code in a file. At the top of your file put the following code

#define DEBUG_FILEASSIST

and then put all you debugging and testing code within a similar set of hash tags thus,

#if DEBUG_FILEASSIST

    private void OnDrawGizmos()
    {
        Debug.Log("Text: ");

        if (Application.isPlaying)
        {
            Gizmos.color = Color.white;
            Gizmos.DrawWireSphere(mousePoint3D, 0.2f);
            Gizmos.DrawLine(transform.position, mousePoint3D);
        }
    }
#endif

now if you comment out the  ##define DEBUG_FILEASSIST , then all code and comments between the #if DEBUG_FILEASSIST will automatically be commented out as well. You don’t need to go through the whole file to find all your debugs and helper code. It will look like this

//#define DEBUG_FILEASSIST

#if DEBUG_FILEASSIST

    private void OnDrawGizmos()
    {
        Debug.Log("Text: ");

        if (Application.isPlaying)
        {
            Gizmos.color = Color.white;
            Gizmos.DrawWireSphere(mousePoint3D, 0.2f);
            Gizmos.DrawLine(transform.position, mousePoint3D);
        }
    }
#endif

Neat eh!
