unity navmesh get remaining distance (infinity)

HI
i am getting problem with navmesh i am trying to get remaining distance when i get distance some times it is showing infinite distance.
how to get the distance , i have noticed that get reaming distance function calculate the nearest node instead of the final destination.

can some one give the solution for this.

 

Know this is a little old but you have to add up the distance between all nodes to get a "correct" distance calculation - tjek out the answer from LightclawJL https://answers.unity.com/questions/732181/nav-remaining-distance-wrong.html

 

This is a bit old, but I came across this thread and I'm sure other people will too. Here's my solution:

Code (CSharp):

1. public float RemainingDistance(Vector3[] points)
2.     {
3.         if (points.Length < 2) return 0;
4.         float distance = 0;
5.         for (int i = 0; i < points.Length - 1; i++)
6.             distance += Vector3.Distance(points[i], points[i + 1]);
7.         return distance;
8.     }

Just pass in yourNavMeshAgent.path.corners

 

Why this is still not fixed in Unity?
Why do we need this useless remainingDistance if its not reliable at all?
Why this is undocumented?

 

Still same in 2023 (in two months 2024)

 

One of the most common cause is the scale of the object you have NavMeshAgent attached to.

Workaround for this is a placeholder as parent =>
1. Create Empty Object and give this object the NavMeshAgent
2.

Put the Object/Character as child of that "EmptyObject" and use
agent = GetComponentInParent<NavMeshAgent>();
to get agent if you have controller script for the character.
​

3. Now scale the mesh fitting size under the "Empty Object" while the parent is scaled 1,1,1 that has the Agent

4.(bonus)

Now you can use the Empty Object's position as a "spawn position" where the object started moving and you can return the "enemy" back to 0,0,0 in case of running out of its range of combat.
Or character's spawn point or check point.​

 

This fixed the issue for me. The agent model I was using had been scaled down quite a lot and was causing the remainingDistance function to return zero. Thanks so much
