Can't access standard asset MotionBlur class in script

Question

I am attempting to make a simple horror game in Unity. Unfortunately when I try to assign a variable to MotionBlur like this;

private var mBlur : MotionBlur;

I am presented with the following error...

BCE0018: The name 'MotionBlur' does not denote a valid type ('not found').
Did you mean 'UnityStandardAssets.ImageEffects.MotionBlur'?

Yet I have the image effects/Standard assets installed. How do I resolve this error?

Answer 1

You need to import the appropriate library before you can reference classes defined in it. In this case, before using MotionBlur you would need to add:

import UnityStandardAssets.ImageEffects;

An alternative is to always reference MotionBlur as UnityStandardAssets.ImageEffects.MotionBlur everywhere in your code - though this isn't my recommendation here, given how verbose it is. (It does become useful if you ever end up with two libraries that define classes using the same name, however.)
