Boat Script

Hi, I found a working boat script bi when i move left or right it spins round and round and does not stop does anyone know how to solve this problem??

Thanks, (Your friendly Noob)

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class boat : MonoBehaviour {
5.  
6.     public float turnSpeed = 1000f;
7.     public float accellerateSpeed = 1000f;
8.  
9.     private Rigidbody rbody;
10.  
11.     // Use this for initialization
12.     void Start ()
13.     {
14.         rbody = GetComponent<Rigidbody>();
15.     }
16.    
17.     // Update is called once per frame
18.     void Update ()
19.     {
20.         float h = Input.GetAxis("Horizontal");
21.         float v = Input.GetAxis("Vertical");
22.  
23.         rbody.AddTorque(0f,h*turnSpeed*Time.deltaTime,0f);
24.         rbody.AddForce(transform.forward*v*accellerateSpeed*Time.deltaTime);
25.  
26.  
27.     }
28. }
29.  

 

I would imagine the original usage of the script depended on some friction between the water and the ship?

 

I think so

 

Try increasing the angular drag on the Rigidbody.

 

Hi
Here is a altenative boat script that is part of the unity community ocean project you can find additional files at the github page if you need .including a couple boat models
