Root Motion based Navmesh characters in Unity

RootMotionNavMesh.cs

using UnityEngine;
using UnityEngine.AI;

namespace PixelWizards.GameSystem.Controllers
{
    /// <summary>
    /// All this does is implement the OnAnimatorMove() for our Units
    /// </summary>
    public class RootMotionNavMesh : MonoBehaviour
    {
        Vector3 worldDeltaPosition = Vector3.zero;
        Vector3 position = Vector3.zero;
        NavMeshAgent agent;
        Animator animator;

        private void Start()
        {
            agent = GetComponent<NavMeshAgent>();
            animator = GetComponent<Animator>();
            // don't update the agent's position, the animation will do that
            agent.updatePosition = false;
        }

        private void Update()
        {
            worldDeltaPosition = agent.nextPosition - transform.position;

            // Pull agent towards character
            if (worldDeltaPosition.magnitude > agent.radius)
                agent.nextPosition = transform.position + 0.9f * worldDeltaPosition;
        }

        private void OnAnimatorMove()
        {
            // Update position based on animation movement using navigation surface height
            position = animator.rootPosition;
            position.y = agent.nextPosition.y;
            transform.position = position;
        }
    }
}

apparently I typed this out raw without actually testing, just posted a fixed version that actually compiles

This way ignores Navmeshes obstacles!
