Underwater effect

[vxv]

Hi.

I have a script to add a fog effect when underwater.
The script is attached to the Invector Camera but it is not working.

Is it something I must add to this ? (I "commented" unnecessary part for this)

//using .....
public float waterHeight;

private bool isUnderwater;
private Color normalColor;
private Color underwaterColor;

// Use this for initialization
void Start ()
{
normalColor = new Color (0.5f, 0.5f, 0.5f, 0.5f);
underwaterColor = new Color (0.22f, 0.65f, 0.77f, 0.5f);
}

// Update is called once per frame
void Update ()
{
if ((transform.position.y < waterHeight) != isUnderwater)
{
isUnderwater = transform.position.y < waterHeight;
if (isUnderwater) SetUnderwater ();
if (!isUnderwater) SetNormal ();

//void setnormal and setunderwater ...

ps. if there is a way to attach effects with invector script please guide me.

Thank you!

This doesn't look like anything regarding Invector included features, so I moved to GameDevelopment Discussion area.

If your script is working correctly, you can enable/disable this component with the swimming inside/outside water events.
