Question by dsillman2000 · Feb 23, 2014 at 05:56 PM · errornamespacenot found

UnityEngine could not be found?

Thanks for looking at my question. I am trying to code my game in MonoDevelop(C#), but I could never compile correctly because, next to the line,

 using UnityEngine;

The error said,

 using UnityEngine;                The type or namespace name 'UnityEngine' could not be found. Are you missing a using directive or assembly reference?

I recently started coding this at my dad's house on a PC. I transferred it over here, to my Mom's house (on a Mac), using Google Drive. Now, all of a sudden this error won't stop showing up.

Help please?

Do you have Unity installed in the second computer ?

I found another way of repairing that: It happened to me after some git mishap, and the references were gone.

To have Unity redo the bindings and reimport the dlls properly, just remove your Library\UnityAssemblies folder and reopen the project.

This also fixed a similar glitch for me that I suspect was linked to changing my editor version. I always upgrade to the most recent, regardless of the consequences!

Hey, you needn't to reinstall your Unity. You can try to add the namespace "UnityEngine" manually. Normally, your UnityEngine reference is here: {Install path of Unity}/UnityProjectTest/Library/UnityAssemblies/UnityEngine.dll I'm not sure how to add it in MonoDevelop but I am sure in Visual Studio. alt text And then, left click "Add Reference...". Now you see the following frame and left click that button named "Browse". alt text Then, find out your UnityEngine.dll and select it. Trust me, I've fixed similar problem. I lost my UnityEditor Reference. All done, you've finished.

Thank you, pointed me in the right direction. Turns out my .dll files were converted to .X$$anonymous$$L files somehow from github. I just deleted the folder and it regenerated the folder when I opened my project again.
