Unity.Cant make my sphere move

Hi,
For the first I wanna say Im a begginner and Im sorry if my mistake was very simple.
But Im making a game which should be simillar to ZigZag game for android.
But when I cant make my ball move I tried so many different ways but nothing worked. This is some code :

using UnityEngine;

using System.Collections;

publicclasssphere : MonoBehaviour

{



void Update()

{

float time = 1;

int direction = 1;

Rigidbody rigidbody = GetComponent<Rigidbody>();

time += (float)0.1;



switch (direction)

{

case 1:

// rigidbody.AddForce(-transform.forward * time);

rigidbody.velocity = transform.TransformDirection(newVector3(time,0, 0));

break;

case 2:

//rigidbody.AddForce(transform.forward * time);

rigidbody.velocity = transform.TransformDirection(newVector3(time,0, 0));

break;

default:

Debug.Log(direction);

break;

}

if (Input.GetKey(KeyCode.LeftArrow))

{


direction = 1;


}

if (Input.GetKey(KeyCode.RightArrow))

{



direction = 2;



}

//rigidbody.AddForce(transform.right*time);

rigidbody.velocity = transform.TransformDirection(newVector3(0, 0, time));

}

}

The comment stuff are things i tried before and didnt work same. The thing which worked was simply changing position of the ball but it didnt look good.
Please help.
Thank you.

 

I see you have a Rigidbody on your sphere. Take that off, and then move it by simply changing transform.position.

 

Well, I need Righidbody because I want my ball to have gravity and I also don't want just to change position because thanthe screen jems

 

Ah, that's unfortunate. Then you'll have to think much harder (and more clearly) about how your script should interact with the motion produced by the physics engine.

 

Hey, have you tried the Roll-A-Ball tutorial? It's an intro to Unity where you build a short game that rolls a ball.

 

Iron-Warrior Not yet, but Ill have a look on it. Thanks, for help.
