public var rigidbody: Rigidbody;
public Rigidbody rigidbody;


The Rigidbody we hit (Read Only). This is null if the object we hit is a collider with no rigidbody attached.

    // Make all rigidbodies we touch fly upwards
    function OnCollisionStay(collision : Collision) {
        // Check if the collider we hit has a rigidbody
        // Then apply the force
        if (collision.rigidbody) {
            collision.rigidbody.AddForce (Vector3.up * 15);
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void OnCollisionStay(Collision collision) { if (collision.rigidbody) collision.rigidbody.AddForce(Vector3.up * 15); } }
