Hinge Joint motor not effecting joint
I am making a 2D top down car racing game. Right now I have a main car body and 4 wheels that connect to it via a hinge joint. There is a script on the body of the car to control the acceleration and turning of the wheels. However when i set the hinge joint motor of the front to wheels to make them turn, I can see the motor value change but I don't actually see the wheels get effected by it.
My code currently looks like this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class NewCarScrip : MonoBehaviour {
public GameObject[] frontWheels;
public GameObject[] backWheels;
public float accelSpeed;
public float turnSpeed;
private GameObject[] wheels;
private Rigidbody2D[] rb;
private HingeJoint2D[] hinge2D;
private JointMotor2D motor2D;
private float accelInput;
private float turnInput;
private Vector2 speed;
// Use this for initialization
void Start ()
{
wheels = new GameObject[frontWheels.Length + backWheels.Length];
frontWheels.CopyTo(wheels, 0);
backWheels.CopyTo(wheels, frontWheels.Length);
rb = new Rigidbody2D[wheels.Length];
hinge2D = new HingeJoint2D[frontWheels.Length];
for (int i=0; i < wheels.Length; i++) //Setup RigidBodies
{
rb[i] = wheels[i].GetComponent<Rigidbody2D>();
}
for (int i = 0; i < frontWheels.Length; i++)
{
hinge2D[i] = frontWheels[i].GetComponent<HingeJoint2D>();
}
}
// Update is called once per frame
void Update ()
{
accelInput = Input.GetAxis("vertical");
turnInput = Input.GetAxis("horizontal");
motor2D.motorSpeed = turnInput * turnSpeed;
//Accelaration codee
speed = transform.up * (accelInput * accelSpeed);
foreach (HingeJoint2D joint2DTemp in hinge2D)
{
if (turnInput != 0)
{
Debug.Log(joint2DTemp.name);
joint2DTemp.motor = motor2D;
}
}
foreach (Rigidbody2D rbTemp in rb)
{
rbTemp.AddForce(speed);
}
}
}

Sorry if this is a noob question. Thank you guys in advance! [1]: /storage/temp/108869-motor-speed.png
