Random Waypoint script. Please help!!

So I'm looking to make my model wander around once at a certain speed in to a random waypoint.
I was thinking. And thank you if you reply!! I've been looking for a solution online and haven't found one.

Code (JavaScript):

1.  
2. function Start ()
3. {
4.     InvokeRepeating("Tick", 300, 300); //Every 3mins run "tick"
5. }
6.  
7. function Tick ()
8. {
9.     //waypoint to a random location. Moving position at certain speed
10. }

Cleaner approach would be to invoke your movement code in FixedUpdate method: http://docs.unity3d.com/ScriptReference/MonoBehaviour.FixedUpdate.html
Assuming your object has a Rigidbody component you should move it around by applying force to it: http://docs.unity3d.com/ScriptReference/Rigidbody.AddForce.html

EDIT: For getting random values for your movement checkout Random class: http://docs.unity3d.com/ScriptReference/Random.html

 

Tried everything and nothing seems to work.

 

Make a blank scene, drop a cube in so you can see it in the camera, and add this little script to the cube itself.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class RunToRandomPoint : MonoBehaviour
5. {
6.     Vector3 targetPos;
7.     float MovementSpeed = 5.0f;
8.     float CloseEnough = 0.5f;
9.  
10.     IEnumerator Start ()
11.     {
12.         targetPos = transform.position;
13.         while(true)
14.         {
15.             // do not move
16.             yield return new WaitForSeconds( 2.0f);
17.             // choose new location
18.             targetPos = new Vector3( Random.Range ( -10, 10), Random.Range( -5, 5));
19.             // wait until we arrive
20.             while( (transform.position - targetPos).magnitude > CloseEnough)
21.             {
22.                 yield return new WaitForSeconds(0.0f);
23.             }
24.         }
25.     }
26.  
27.     void Update ()
28.     {
29.         // have we arrived?
30.         if ((transform.position - targetPos).magnitude > CloseEnough)
31.         {
32.             // nope, turn to and go
33.             transform.LookAt( targetPos);
34.             transform.position += (targetPos - transform.position).normalized *
35.                 MovementSpeed * Time.deltaTime;
36.         }
37.     }
38. }
39.
