public var velocity: Vector3;
public Vector3 velocity;

Description

The velocity vector of the rigidbody.

In most cases you should not modify the velocity directly, as this can result in unrealistic behaviour. Don't set the velocity of an object every physics step, this will lead to unrealistic physics simulation. A typical example where you would change the velocity is when jumping in a first person shooter, because you want an immediate change in velocity.

var rb: Rigidbody;

function Start() { rb = GetComponent.<Rigidbody>(); }

function FixedUpdate () { if (Input.GetButtonDown("Jump")) { rb.velocity = Vector3(0,10,0); } }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public Rigidbody rb; void Start() { rb = GetComponent<Rigidbody>(); } void FixedUpdate() { if (Input.GetButtonDown("Jump")) rb.velocity = new Vector3(0, 10, 0); } }
