How do I make an enemy AI jump?

I am making my Ludum Dare entry and want my AI to try and out run the player to a certain object, however I want the AI to jump. I am totally new to game development and scripting. Here is my script so far, what do I have to add to make the AI jump and can I add it to this script or should I make a new one?

Script:

var target : Transform; var moveSpeed = 3; var rotationSpeed = 3; var myTransform : Transform;

function Awake(){ myTransform = transform; }

function Start(){ target = GameObject.FindWithTag("EndPlatform").transform; }

function Update () { var lookDir = target.position - myTransform.position; lookDir.y = 0;

myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(lookDir), rotationSpeed*Time.deltaTime); myTransform.position += myTransform.forward moveSpeed Time.deltaTime; }
