help fix my script

Question

ok so ive been converting some script a friend gave me from C# to java script, the script is suspost to give movement to rigidbody like you would do with a character controler for a racing game, im trying not to use too much of other peoples script so I can work it out for myself, t$$anonymous$$s is the script

var speed = 10;

FixedUpdate(); { horizontal = Input.GetAxis("Horizontal"); vertical = Input.GetAxis("Vertical");

 Vector3 a = transform.eulerAngles;

 if(horizontalInput > 0.1) transform.eulerAngles = new Vector3(a.x, a.y + (value  Time.Deltatime  10), a.z);

 else if(horizontalInput < 0) transform.eulerAngles = new Vector3(a.x, a.y - (value  Time.Deltatime  10), a.z);

 Vector3 moveDirection = new Vector3(verticalInput*speed,0,0);

if(verticalInput > 0.1) rigidbody.AddRelativeForce(moveDirection,ForceMode.Acceleration); }

ok :) please help, unity does not like t$$anonymous$$s line: horizontal = Input.GetAxis("Horizontal");
it complains about the "=" sign, please help!

The problem is that you have a semi colon after FixedUpdate(). Remove it, and it should work.

You also forgot to add "function" in front of FixedUpdate().

You forget to declare the variables too...

horizontal = Input.GetAxis("Horizontal");
vertical = Input.GetAxis("Vertical");

To

var horizontal = Input.GetAxis("Horizontal");
var vertical = Input.GetAxis("Vertical");

and

if(horizontalInput > 0.1){

Where horizontalInput was declared?

Where to begin? I found 13 "errors" in 14 lines of code, including scope brackets.

You're using an integer speed variable.
You're missing the function keyword.
You're having a semicolon after function FixedUpdate().
You're incorrectly declaring the variables:
- a
- moveDirection
You're using variables that doesn't exist:
- Time.Deltatime
- horizontal
- vertical
- horizontalInput
- verticalInput
- value
You're rotating a transform where you ought to add torque to the rigidbody.
You're applying acceleration to the right rather than forward.

I'd change the script to:

var speed = 10.0f;

function FixedUpdate() {  
   var horizontal = Input.GetAxis("Horizontal");
   var vertical = Input.GetAxis("Vertical");  
   var torque = Vector3.up  horizontal  speed;
   var acceleration = Vector3.forward  vertical  speed;  
   rigidbody.AddRelativeTorque(torque);
   if(vertical > 0.1f)
      rigidbody.AddRelativeForce(acceleration, ForceMode.Acceleration);
}
