Take a look at the Spline Controller script on the wiki - you can set up two (or possibly more, so that turning looks better at the ends) control points and have your object walk between them

http://www.unifycommunity.com/wiki/index.php?title=Spline_Controller

Preferably download the c# version, as it has less bugs than the js version (and is 3.0 compatible if I remember correctly) - and looking at the site again, maybe even the iPhone compatible version, as it's got another fix in

Thanks, $$anonymous$$an thats exactly what i wanted!

Answer 2

i got most of the following from a great youtube vid, but here are the scripts and instructions and stuff

make an empty game object, call it "waypoint" or whatevers easy and attatch this 2 it you can see it on creating but not on game which is handy :).

function OnDrawGizmos(){

Gizmos.DrawIcon(transform.position,"AITuts/Materials/Textures/WayPoint");

}

ok then put this were u want it 2 move. put the following on what you want to go there (your AI)

var waypoint : Transform[];

var speed : float = 20;

private var currentWaypoint : int;

var loop : boolean = true;

function Awake(){

waypoint[0] = transform;

} function Update () {

if(currentWaypoint < waypoint.length){

 var target : Vector3 = waypoint[currentWaypoint].position;

 var moveDirection : Vector3 = target - transform.position;

 var velocity = rigidbody.velocity;
 if(moveDirection.magnitude &lt; 1){
     currentWaypoint++;
 }
 else{
     velocity = moveDirection.normalized * speed;
 }

} else{ if(loop){ currentWaypoint=0; } else{ velocity = Vector3.zero; } }

rigidbody.velocity = velocity;

}

then add a "rigidbody" to your AI (it's best 2 use a sphere or a capsule for were you attach your script)

then on the object click the name "waypoint" and change the "size" number to how ever many waypoints you want. with the waypoints i explained earlier drag them into the empty slots. when it gets to the end it should do a loop, if it doesn't make the size 1 bigger and but the 1 before the last to the end, if this is a bit confusing i recommend the youtube vid (link at the end) there are 3 vids in the series that will help with what i explained if you want it to point and shoot, say and i can help with that 2 :)
