Question by Thernos · Oct 14, 2019 at 05:51 PM · scripting problemupdateapiupdate problem

Just updated to newest Unity version but something's missing

So I'm trying to follow a tutorial on YouTube and there are a few problems persisting with the code on my machine:

  1. The C# script uses face.ConstructMesh(), but Unity's console says NullReferenceException: Object reference not set to an instance of an object, pointing at the line that has face.ConstructMesh();

  2. After making a new C# script and trying to change public class Name : MonoBehavior { to public class Name : ScriptableObject {, there is no highlighting on ScriptableObject. After adding [CreateAssetMenu()], there's still no highlighting. It's like Visual Studio doesn't recognize those two things.

It's led me to a single conclusion: something from the newest update didn't transfer over, like I'm working with an older version of UnityEngine that is missing things like not having to reference this. I can't use the Automatic API Updater because I'm actually trying to use "future code" instead of "obsolete/past code"... Help?

Your face var is likely null. This might be a transition problem with unity, maybe not. Use break points to figure out why it is null.


Does VS recognize other values? Did you update the Unity plugin on Visual Studio?

I was using VS Community 2015, had both 2015 and 2017 installed so I swapped over to 2017, updated VS 2017 Tools for Unity, no change.

$$anonymous$$y previous Unity version was 5.6.1f1, and I'm still able to use all of the old unity things in VS like Vector3, $$anonymous$$esh, mesh.RecalculateNormals(), gameObject, etc.

I'm now using 2019.2.9f1 and it doesn't recognize ScriptableObject and CreateAsset$$anonymous$$enu. The script is exactly as it is in the tutorial, but if I right-click in the asset folder in Unity the topmost option is Create > ins$$anonymous$$d of the ScriptableObject option to make a settings file.
