Namespace UnityStandardAssets not found

The Unity documentation says that in order to access image effects through scripting I must include:
using UnityStandardAssets.ImageEffects;

Straightforward. However, when going back to Unity, the console gives me the following error regarding this line:
Assets/Scripts/GUI/Inventory.cs(3,7): error CS0246: The type or namespace name `UnityStandardAssets' could not be found. Are you missing a using directive or an assembly reference?

I have all image effects working correctly inside the project, but I cannot access them through scripting. What's going on?

P.S.: Unity 4.6.3

 

I imagine you'll also need to import the unity package into your project.

Assets > Import Package > Effects

 

Afaik this only applies to Unity 5 and is not needed in Unity 4.
In order to call Image Effects, use GetComponent:

C#

Code (CSharp):

1. GetComponent<DesiredImageEffect>()
2. EX: Camera.main.GetComponent<Vignetting>().enabled = true/false;

JS:

Code (JavaScript):

1. GetComponent("DesiredImageEffect")
2. EX: Camera.main.GetComponent("Vignetting").enabled = true/false;

 

Indeed this works, thank you very much.

What had thrown me off was MonoDevelop's code completion does not pick this up at all and displays <Vignetting>().enabled in red. But the code works in Unity. Having code completion would be useful but is not a necessity.

 

Ok, It was done with this operation

 

*using UnityStandardAssets.Character.FirstPerson;*
including this line...it throws an error this

*Assets\GroundBehaviour.cs(4,7): error CS0246: The type or namespace name 'UnityStandardAssets' could not be found (are you missing a using directive or an assembly reference?*

 

I am trying to make myself get in a standard assets jet. But it still doesn't work

 

Please tell me if you a way.

 

you have to add standard assets pack from unity store if you don't have already...

 

I have added standard assets pack. Yet I am getting same error.

 

I am not getting how should I do the asset thing you told, as when i am clicking import package, there's only one thing listed - "custom package". Please tell me how to fix this whole errrorrr!

 

That comment was for Unity 4.6.3 as they talked about it. That package was deprecated and moved to the Asset Store.
https://assetstore.unity.com/packages/essentials/asset-packs/standard-assets-for-unity-2018-4-32351

But you will need to use an older Unity version to use it.

 

so what should I do. Actually I am not able to add/drag that "move" scripting file to the Sphere gameobject. Whenever i do, that popup's coming. Please help!
I think thats the Mono Behaviour thing which is coming in between. Please tell what to do. No other option except Visual studio is coming in the preferences, like in following this thing - "Edit> Preferences > External Tools> Here we have the option: External Script Editor: we can select MonoDevelop (built-in)"

 

I'm guessing you're trying to follow some sort of tutorial. Check what version of Unity was written for. Download that version if you want to follow that tutorial. Or choose another tutorial, there are plenty without using that package too.
