JavaScript => public var rigidbody: Rigidbody;
C# => public Rigidbody rigidbody;

Description 描述

The Rigidbody of the collider that was hit. If the collider is not attached to a rigidbody then it is null.

碰到的该碰撞器上的刚体。如果碰撞器上没有附加刚体，那么返回null。

JavaScript:

	// Apply a force to a clicked rigidbody object.
 
	// The force applied to an object when hit.
	var hitForce: float;
 
	function Update() {
		if (Input.GetMouseButtonDown(0)) {
			var hit: RaycastHit;
			var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
			if (Physics.Raycast(ray, hit)) {
				if (hit.rigidbody != null)
					hit.rigidbody.AddForce(ray.direction * hitForce);
			}
		}
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float hitForce;
    void Update() {
        if (Input.GetMouseButtonDown(0)) {
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit))
                if (hit.rigidbody != null)
                    hit.rigidbody.AddForce(ray.direction * hitForce);
 
 
        }
    }
}
