I change the code:
if (!constraint.Suitable (nearestNode.node) || (constraint.constrainDistance && (nearestNode.clampedPosition - position).sqrMagnitude > maxNearestNodeDistanceSqr)) {
return new NNInfo (nearestNode);
}
it work… but there is still a waring:
Canceled path because a new one was requested.
This happens when a new path is requested from the seeker when one was already being calculated.
For example if a unit got a new order, you might request a new path directly instead of waiting for the now invalid path to be calculated. Which is probably what you want.
If you are getting this a lot, you might want to consider how you are scheduling path requests.
