Hi everyone, I receive this error during test sample scene: with 8 other errors in screenshot Any feedback is appreciated be safe everyone and stay healthy, I apologize it is not a Ben a Rick class 
Assets\PortalReignDiscordant\Scripts\NavAgentExample.cs(6,9): error CS0246: The type or namespace name ‘NavMeshAgent’ could not be found (are you missing a using directive or an assembly reference?)
Sounds like there is improper definitions in the NavAgentExample.cs script. Can I see the script in question?

I notice just now the scripts do not have headers like this :
I will add a let you results :

using System.Collections.Generic;
Hi Riley, I added the following lines but these line of code were created in this script Thank you for any feedback
using UnityEngine;
using System.Collections.Generic;
public class NavMeshExample : MonoBehaviour
{
Lines of code changed after adding above
// If we don't have a path and one isn't pending then set the next
// waypoint as the target, otherwise if path is stale regenerate path
if ((!HasPath && !PathPending) || PathStatus == UnityEngine.AI.NavMeshPathStatus.PathInvalid /*|| PathStatus==NavMeshPathStatus.PathPartial*/)
SetNextDestination(true);
else
All that code is within a class or just on it’s own? Make sure you got all your closing curling brackets.
It is just on its own I believe I did check my curling brackets will check again. I following a class instructions this one:
Send the full script you have and I’ll see if I can get it sorted out.
Hi Riley, I think you ae super for this
These are all the scripts I work with.

Okay I think my next question is all this code in a single file or seperate files?
I apologize for that will separate got a phone call from client had to stop what I was doing hold on.
