Pause Menu Script Help?

Or, above all else, you can not copy peoples code, and actually hand code it and use it as an example, and code from it to guide you along your way like it's meant to...

The sepia effect is obviously used by the actual creator... And it's an easy fix, and it's probably in the first tutorial on Java programming that you look up to on Google/Youtube, but to be honest, I think you should learn the hard way rather than have others code for you...

Make sure you define the identifier 'SepiaToneEffect'

It seens that you script refer to a variable named SepiaToneEffect but it's not declared first.

Or refer to a component (or script) that is not applied to your GameObject, in this case, make sure you are using the GetComponent() function and the component is applied to your gameobject.

UPDATE:

Here is the line of the your script:
pauseFilter = Camera.main.GetComponent(SepiaToneEffect);
You need to add a component called SepiaToneEffect to your main camera.
This effect only works on Pro version, to have access to this component you need to "Import package", go to your unity install folder and search for pro package:

C:\Program Files\Unity\Editor\Standard Packages\Pro Standard Assets.unityPackage

Hope this help you. Good look!

You should be able to comment out that line.
