whats wrong wrong with my script

Dude, this is your script laid out neatly:

var speed = 7.0; var rotateSpeed = 4.0;

 GetComponent(CharacterController);

 //Rotate around y - axis
 transform.Rotate(0, Imput.GetAxis ("Horizontal")  * rotateSpeed, 0);

 //  Move forward / backward
 var forward = transform.TransformDirection(Vector3).forward;
 var curSpeed = speed * Imput.Getaxis("Vertical");
 controller.SimpleMove(forward * curSpeed);

And this is your script (hopefully) without compilation errors:

@script RequireComponent(CharacterController)

 //Rotate around y - axis
 transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

 //  Move forward / backward
 var forward = transform.TransformDirection(Vector3).forward;
 var curSpeed = speed * Input.Getaxis("Vertical");
 controller.SimpleMove(forward * curSpeed);

First - try and lay out your scripts so they are readable. Way easier to spot mistakes and go over the codes that way. I hope you just copy-pasted it wrong, because if you continue this way, when your scripts get longer and more complex - they will become more and more of a mess...

Second - I'm all about messing around with the code, trial and error and stuff, but when you're starting out - try and understand the little things as much as possible. Do some tutorials, see some code other people wrote.

Third - try and play spot the difference between what you posted, and the code I did. I don't know exactly which line had the problem, but if you had corrected it - you would have another one, and another one. I spotted at least 3 syntax errors :/

Don't take it hard - I'm not criticizing, just trying to help you out here...

Would this work?

var speed = 3.0; var rotateSpeed = 3.0;

You made a couple of mistakes.

o ok thanks for you r help

ya but it says this i tried to fix it but i dont know whats wrong it says Assets/Standard Assets/NewBehaviourScript.js(14,47): BCE0023: No appropriate version of 'UnityEngine.Transform.TransformDirection' for the argument list '(System.Type)' was found.

heres my scritpt

script RequireComponent(CharacterController)

var speed = 7.0; var rotateSpeed = 4.0;

function Update() { var controller : CharacterController = GetComponent(CharacterController);

//Rotate around y - axis transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

// Move forward / backward var forward = transform.TransformDirection(Vector3).forward; var curSpeed = speed Input.Getaxis("Vertical"); controller.SimpleMove(forward curSpeed);

}
