var position : Vector3

Description

The position of the rigidbody.

This is similar to setting transform.position, however the position will only be applied to the transform at the end of the physics step. If you want to continously move a rigidbody or kinematic rigidbody use MovePosition and MoveRotation instead

function Start () {
    rigidbody.position = Vector3.zero;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Start() {
        rigidbody.position = Vector3.zero;
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    def Start():
        rigidbody.position = Vector3.zero
