Hey guys I am new to unity Pro. I have what seems to be a simple problem but I am not much of a programmer. I wanted the image effect to fade in when the player touches an object. Let the image effect stay for a minute or two, then fade out again

Any ideas please let me know!

I don’t know much about the Pro version, but I guess you’ll need to work with coroutines. Something like :

function Start()
{
    yield FadeIn();
    yield WaitForSeconds(120);
    yield FadeOut();
}

function FadeIn(){
    var alpha : float = 0.0;
    while( alpha < 1.0 ){
        // Do something with that alpha
        alpha += Time.deltaTime;
        yield null;
    }
}

function FadeOut(){
    var alpha : float = 1.0;
    while( alpha > 0.0 ){
        // Do something with that alpha
        alpha -+= Time.deltaTime;
        yield null;
    }
}
