Instantly Turn with Nav Mesh Agent

The solution for me: Manually control the rotation.

public class AgentControler: MonoBehaviour {

 private NavMeshAgent agent;
 private const float rotSpeed= 20f;

 void Start() {
     agent = GetComponent<NavMeshAgent>();
     agent.updateRotation = false;
 }

 void Update() {
     InstantlyTurn(agent.destination);
 }

 private void InstantlyTurn(Vector3 destination) {
     //When on target -> dont rotate!
     if ((destination - transform.position).magnitude < 0.1f) return; 
     
     Vector3 direction = (destination - transform.position).normalized;
     Quaternion  qDir= Quaternion.LookRotation(direction);
     transform.rotation = Quaternion.Slerp(transform.rotation, qDir, Time.deltaTime * rotSpeed);
 }

//note: We can return the rotation control to the agent when it moves. for example:

agent.updateRotation = ((agente.velocity).magnitude > 0.2);

//When there are more agents or obstacles is interesting.

I did the opposite of what others suggested, jack the acceleration way up (I did 999, though I didn't find the min value to make it work).

Speed = 20 (whatever you want here) Angular Speed = 999 Acceleration = 999 Stopping Distance = 0 Auto Braking = True

That seemed to work for me

Best approach would probably be, is to write your own little method to turn your object towards NavAgent's first turn point.

First use NavAgent to calculate the path and then use the path's waypoints to determine where your object should turn, after your turning method send the agent on its way.

You can always turn the rotation speed of the navmeshagent way up: the faster this is, the faster it rotates towards destination. This combined with turning acceleration down a bit might be a simple way to solve this problem. if the acceleration is low, it will take longer for the object to get moving, this was how I personally fixed the issue.

With regards to animation, you might want to make a check that the object is moving a certain speed (check the vector3.distance(newpos, oldpos) ) before playing something like a walking animation. Maybe something like:

float distance = vector3.distance(newpos, oldpos); if (vector3.distance(navmeshagent.destination.point, gameobject.transform.position) > 0.5f && distance < 0.5f){ animation.play("turning"); } else if (vector3.distance(navmeshagent.destination.point, gameobject.transform.position) > 0.5f && distance < 0.5f){ animation.play("running"); } else animation.play("idle");

I'm still trying to figure out a way to find which absolute direction the navmeshagent is rotating in. Hard because when it rotates 360 degrees it switches from negative to positive, visa versa.

anyways hope this helps!
