My bike refuses to roll

Unity Engine

Hi, i’m creating a script to roll a motorcycle. I use the rigidbody.AddForce to move forward and the rigidbody.AddTorque to spin my moto but when i do it, it doesn’t work like i want.
This is my script… Please somebody to help me:

class Zem_Controller:MonoBehaviour
{
public float speed_translation = 100.0F;
public float speed_rotation = 100.0F;
private Vector3 movement_zem;

void FixedUpdate()
{
//if (Input.GetKey (“d”))

float movement_forward = Input.GetAxis (“Vertical”);
movement_zem = new Vector3(0.0F,0.0F,movement_forward);
rigidbody.AddForce (movement_zem * 5 * speed_translation );

float movement_rotation = Input.GetAxis (“Horizontal”);
movement_zem = new Vector3 (0.0F, movement_rotation, 0.0F);
rigidbody.AddTorque (movement_zem * 1000 * speed_rotation);

}

}

Throw this in there, see if the values are what you expect:

Debug.Log(Input.GetAxis ("Horizontal") + ", " +speed_rotation)

Please, i’m just a beginner ! What value i must have to know that my script is working?

Well you would want the horizontal axis to change when you press the keys, if it doesn’t change that’s an issue, double-check how you’ve got the axis set up under Project Settings> Input.
And speed_rotation I guess make sure it’s not zero. You mention 100f in th e declaration, but it could have been set something else in the inspector for this game object.
