Rigidbody.AddRelativeForce

Parameters

Description

Adds a force to the rigidbody relative to its coordinate system.

Force can be applied only to an active rigidbody. If a GameObject is inactive, AddRelativeForce has no effect.

Wakes up the Rigidbody by default. If the force size is zero then the Rigidbody will not be woken up.

For more information on how ForceMode affects velocity, see Rigidbody.AddForce.

using UnityEngine;
using System.Collections;

// Add a thrust force to push an object in its current forward
// direction (to simulate a rocket motor, say).
public class ExampleClass : MonoBehaviour
{
    public float thrust;
    public Rigidbody rb;
    void Start()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate()
    {
        rb.AddRelativeForce(Vector3.forward * thrust);
    }
}
