Zombie script

I am trying to make a zombie game. I keep on getting compiler err. can any one fix it?

here it is

var target : Transform; //the enemy's target var moveSpeed = 3; //move speed var rotationSpeed = 3; //speed of turning var attackThreshold = 1.5; // distance within which to attack var chaseThreshold = 10; // distance within which to start chasing var giveUpThreshold = 20; // distance beyond which AI gives up var attackRepeatTime = 1; // delay between attacks when within range

private var chasing = false; private var attackTime = Time.time;

var myTransform : Transform; //current transform data of this enemy

function Awake(){ myTransform = transform; //cache transform data for easy access/preformance }

function Start(){ target = GameObject.FindWithTag("Player").transform; //target the player }

function Update () { // check distance to target every frame: var distance = (target.position - myTransform.position).magnitude; if (chasing) { //rotate to look at the player myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime); //move towards the player myTransform.position += myTransform.forward moveSpeed Time.deltaTime; // give up, if too far away from target: if (distance > giveUpThreshold) { chasing = false; } // attack, if close enough, and if time is OK: if (distance < attackThreshold && Time.time > attackRepeatTime) { target.SendMessage("ApplyDamage",10); // Attack! (call whatever attack function you like here) } if (distance < attackThreshold) { moveSpeed=0; //stop when close enough } attackTime = Time.time+ attackRepeatTime; } else { // not currently chasing. // start chasing if target comes close enough if (distance < chaseThreshold) { chasing = true; } } }

function OnTriggerEnter (other: Collider) { if (other.gameObject.CompareTag("Bullet")){ chaseThreshold=100000000; } }
