Changing Image Effect 'Depth Of Field' in run time

[Caiuse]

I'm having trouble with accessing the 'Depth of Field' image effect that's placed on the main camera in my scene.

I'm trying to change two things the "Focus On Target" and also the effect amount so I can fade it completely away. (I'm aware that there isn't a current Effect Amount variable so please could someone explain how I could go about adding this to the depth of field effect)

Any ideas? Cheers - C

I think you would just assign 'ObjectFocus' to whatever object you want to focus on, something like

Camera.main.GetComponent(DepthOfField).objectFocus = myCoolObject; // or myCoolObject.transform?

and the amount of effect seems to be 'focal size' (except at zero it's more intense) so maybe:

if (amount > 0)
{
  Camera.main.GetComponent(DepthOfField).enabled = true;
  Camera.main.GetComponent(DepthOfField).focalSize = amount;
}
else
  Camera.main.GetComponent(DepthOfField).enabled = false;

I don’t know what Unity version you guys are using, but there is no “Depth Of Field” script in Unity 3.5 or Unity 4. There is a “Depth Of Field (34)”, a “Tilt Shift”, and a “Depth Of Field (Scatter)”. Is there something I’m missing, like a built in script or something? Or did you just write “DepthOfField” because different people use differnet scripts? I’m mentioning this not because I’m that jerk who corrects people or anything but because the script is not working for me and I am wondering if there is an obvious reason why. The “amount” in my script is the value of a knob from the iGUI user interface plugin. Here is the script I have:

   public void knob1_ValueChange(iGUIKnob caller){
    		if (knob1.value > 0)
    		{
    			Camera.main.GetComponent(DepthOfField34).objectFocus = gameObject.transform;
    			Camera.main.GetComponent(DepthOfField34).enabled = true;
    			Camera.main.GetComponent(DepthOfField34).focalZDistance = knob1.value;
    		}
    		else
    			Camera.main.GetComponent(DepthOfField34).enabled = false;
    	}

So what I’m wondering is, is there something obviously wrong with my script, or is this just because my version of unity is too new? And yes I did add the component to the main camera and I did use the right variables (I think).

Thanks/hope my comment was somewhat helpful!
