Question by Bramburyk · Jan 10, 2011 at 06:40 PM · aicar

,,SeekSteer" problem...

I took the SeekSteer script from the http://www.unifycommunity.com/wiki/index.php?title=SeekSteer site.

using UnityEngine; using System.Collections;

public class SeekSteer : MonoBehaviour {

 public Transform[] waypoints;
 public float waypointRadius = 1.5f;
 public float damping = 0.1f;
 public bool loop = false;
 public float speed = 2.0f;
 public bool faceHeading = true;

 private Vector3 currentHeading,targetHeading;
 private int targetwaypoint;
 private Transform xform;
 private bool useRigidbody;
 private Rigidbody rigidmember;


 // Use this for initialization
 protected void Start ()
 {
     xform = transform;
     currentHeading = xform.forward;
     if(waypoints.Length<=0)
     {
         Debug.Log("No waypoints on "+name);
         enabled = false;
     }
     targetwaypoint = 0;
     if(rigidbody!=null)
     {
         useRigidbody = true;
         rigidmember = rigidbody;
     }
     else
     {
         useRigidbody = false;
     }
 }


 // calculates a new heading
 protected void FixedUpdate ()
 {
     targetHeading = waypoints[targetwaypoint].position - xform.position;

     currentHeading = Vector3.Lerp(currentHeading,targetHeading,damping*Time.deltaTime);
 }

 // moves us along current heading
 protected void Update()
 {
     if(useRigidbody)
         rigidmember.velocity = currentHeading * speed;
     else
         xform.position +=currentHeading * Time.deltaTime * speed;
     if(faceHeading)
         xform.LookAt(xform.position+currentHeading);

     if(Vector3.Distance(xform.position,waypoints[targetwaypoint].position)<=waypointRadius)
     {
         targetwaypoint++;
         if(targetwaypoint>=waypoints.Length)
         {
             targetwaypoint = 0;

         }
     }
 }


 // draws red line from waypoint to waypoint
 public void OnDrawGizmos()
 {
     Gizmos.color = Color.red;
     if(waypoints==null)
         return;
     for(int i=0;i< waypoints.Length;i++)
     {
         Vector3 pos = waypoints[i].position;
         if(i>0)
         {
             Vector3 prev = waypoints[i-1].position;
             Gizmos.DrawLine(prev,pos);
         }
     }
 }

}

But when my car reaches the first waypoint it keeps moving on and crashes into the first wall...it goes directly forward. Why my car keeps going on and doesn't stop at the first waypoint?

Adjust your waypoint radius to something much greater.
