NavMeshAgent Patrol-HowTo incorrect

Web Resources
1

In the Navigation Manual there is a HowTo for “Making an Agent Patrol Between a Set of Points” which acquires the next waypoint for a NavMeshAgent in Update() which resulted in skipping some waypoints when copying it in my project.

I suppose that’s because you should not poll agent.remainingDistance as that property is not updated immediately after getting a new destination but rather after some frames (?).

An easy fix would be to just combine it with the agent.pathPending property thus delaying the proximity check until the pathfinding is done without refactoring the rest of the tutorial code.

Problem:

void Update () {
  // Choose the next destination point when the agent gets
  // close to the current one.
  if (agent.remainingDistance < 0.5f)
    GotoNextPoint();
}

Fix:

void Update () {
  // Choose the next destination point when the agent gets
  // close to the current one.
  if (!agent.pathPending && agent.remainingDistance < 0.5f) {
    GotoNextPoint();
  }
}

Hope that helps and this is the correct place to post these kinds of issues.

It is, it does, and we’d like to thank you for taking the time to do so :slight_smile: I’ll add it to our list of fixes. Thanks again!
