Unity中实现3D物体跳跃

<p>目前主要实现的是鼠标点击任何地方 所绑定的物体都会跳跃（点击的越快，物体就回在上次点击的基础之上在进行等比的高度增加）。</p><p>代码如下：</p>

using UnityEngine;
using System.Collections;

public class CylinderMove : MonoBehaviour {

private float speed = 5f;

private  Rigidbody body;

public static CylinderMove instance;
public static CylinderMove Instance
{
get
{
if(instance == null)
{
instance = new CylinderMove();
}
return instance;
}
}
// Use this for initialization
void Start ()
{
body = transform.GetComponent<Rigidbody>();
}

// Update is called once per frame
void Update ()
{
if(Input.GetMouseButtonDown(0))
{
Debug.Log("ssss");
JumpFunc();
}

Debug.DrawRay(transform.position,Vector3.down,Color.black);
}
public  void JumpFunc()
{
RaycastHit hit;
if(Physics.Raycast(transform.position,Vector3.down,out hit))
{

body.AddForce(Vector3.up * 3000);
}
}

}
