Twirl Image Effect via Script

Unity Engine
1

What is the best way to adjust parameters of the image effects through script?
I would like to increase the TwirlEffect angle when a collision between two objects occurs.

Cheers.

Image Effects are just scripts like any other script. So the best is getting to the image effect either by exposing a variable that you setup in the inspector:

var twirl : TwirlEffect;

Or getting the effect from camera like

twirl = camera.GetComponent(TwirlEffect);

Then you just modify it’s properties:

twirl.angle = 100.0;

I’ve tried all of these and keep getting Null reference errors, or cannot reference this this when declaring a variable errors. :frowning:

//var twirl= Camera.main.GetComponent(TwirlEffect);
//var twirl : TwirlEffect;
var twirl = camera.GetComponent(TwirlEffect);

function OnCollisionEnter(collision : Collision) {
twirl.angle = 100.0;
}

Ah sweet I got it. I just had to select the main camera in the inspector. I kept trying to fing the TwirlEffect script itself.

Thanx
