i get this error after updating Unity 5.4 to Beta 5.50b8
“Assets/Standard Assets/Characters/ThirdPersonCharacter/Scripts/AICharacterControl.cs(10,16): error CS0246: The type or namespace name
NavMeshAgent' could not be found. Are you missing UnityEngine.AI’ using directive?”
i’ve read some changes in Unity Beta API Changes:
-“AI: NavMesh related types are moved from namespaces UnityEngine and UnityEditor to UnityEngine.AI and UnityEditor.AI”
but how to Fix the error?
