Convert simple C# to JS

Questions & Answers
1

I am new to coding trying to learn what wrong with my own converting below because it gave error after convert.

Original C#

using UnityEngine;
using System.Collections;


public class boat : MonoBehaviour {

	public float turnSpeed = 1000f;
	public float accellerateSpeed = 1000f;

	private Rigidbody rbody;

	// Use this for initialization
	void Start () 
	{
		rbody = GetComponent<Rigidbody>();
	}
	
	// Update is called once per frame
	void Update () 
	{
		float h = Input.GetAxis("Horizontal");
		float v = Input.GetAxis("Vertical");

		rbody.AddTorque(0f,h*turnSpeed*Time.deltaTime,0f);
		rbody.AddForce(transform.forward*v*accellerateSpeed*Time.deltaTime);


	}
}

My own JS converted

public var boat : GameObject;

public var turnSpeed : float = 1000f;
public var accellerateSpeed : float = 1000f;

private var Rigidbody; rbody;

function Start(){
     var rbody = GetComponent<Rigidbody>();

function Update(){
        float h = Input.GetAxis("Horizontal");
		float v = Input.GetAxis("Vertical");

		rbody.AddTorque(0f,h*turnSpeed*Time.deltaTime,0f);
		rbody.AddForce(transform.forward*v*accellerateSpeed*Time.deltaTime);


	}
}

public var boat : GameObject;

 public var turnSpeed : float = 1000f;
 public var accellerateSpeed : float = 1000f;
 
 private var rbody : Rigidbody;
 
 function Start(){
      rbody = GetComponent.<Rigidbody>();
 }

 function Update(){
         var h : float = Input.GetAxis("Horizontal");
         var v : float = Input.GetAxis("Vertical");
 
         rbody.AddTorque(0f,h*turnSpeed*Time.deltaTime,0f);
         rbody.AddForce(transform.forward*v*accellerateSpeed*Time.deltaTime);
 
 
     }

There were a few syntax errors with declaration and typecasting.

I have not tested it but I think that this should work. You have some mistakes in declaration.

#pragma strict

//Creates Boat Class extending from MonoBehaviour
public class boat extends MonoBehaviour {
	
	//Declare variables of the class
	var turnSpeed : float = 1000f;
	var accellerateSpeed : float = 1000f;

	//Do not forget to use the type after colon, never before
	private var rbody : Rigidbody;

	function Start() {
		rbody = GetComponent(Rigidbody) as Rigidbody;
	}

	function Update(){
		var h : float = Input.GetAxis("Horizontal");
		var v : float = Input.GetAxis("Vertical");

		rbody.AddTorque(0f,h*turnSpeed*Time.deltaTime,0f);
        rbody.AddForce(transform.forward*v*accellerateSpeed*Time.deltaTime);
	}
}
