NavMeshObstacle.velocity

Description

Velocity at which the obstacle moves around the NavMesh.

// Simple behaviour to block the player who we assume is controlled
// by a NavMeshAgent.
var obs: UnityEngine.AI.NavMeshObstacle;
var player: Transform;
var moveSpeed: float;

function Start () {
    obs = GetComponent.<UnityEngine.AI.NavMeshObstacle>();
}

function Update() {
    // Find the heading to a target point five units in front of the player.
    var targetPoint = player.TransformPoint(Vector3.forward * 5.0);
    var heading = (player.position - transform.position).normalized;

    // Set the obstacle to move to the target at a predetermined speed.
    obs.velocity = heading * moveSpeed;
}
