Unity3D 5.0简单的实现跳跃功能

这里是一个简单的跳跃，5.0和其他版本貌似不一样，并且，再起跳功能做的不完全。

不过一个基本的思路在这里。

首先，射线检测，这里是利用一个空对象，放到目前对象的下面

然后，在绑定主角的脚本文件上开始写脚本：

using UnityEngine;
using System.Collections;

public class move : MonoBehaviour {

	// Use this for initialization
	private bool grounded = false;
	private Transform groundcheck;
	private bool jump = false; //角色的跳起
	private Rigidbody2D hero;
	public float jumpy = 360f;
	public AudioClip jumpclips; //跳跃音频
	void Start () {
		groundcheck = transform.Find ("groundcheck");
		//hero = transform.Find ("pk_0");

	}

	// Update is called once per frame
	void Update () {
		if(Input.GetKey(KeyCode.W)){

			gameObject.transform.Translate(Vector3.up*5*Time.deltaTime);
		}
		if(Input.GetKey(KeyCode.S)){
			gameObject.transform.Translate(Vector3.down*5*Time.deltaTime);
		}
		if(Input.GetKey(KeyCode.A)){
			gameObject.transform.Translate(Vector3.left*5*Time.deltaTime);
		}
		if(Input.GetKey(KeyCode.D)){
			gameObject.transform.Translate(Vector3.right*5*Time.deltaTime);
		}
		//与地面接触为真，太能够进行跳跃
		grounded = Physics2D.Linecast (transform.position, groundcheck.transform.position);
		if(grounded && Input.GetKeyDown(KeyCode.J)){
			jump = true;

			//设置角色的起跳功能
			if(jump == true){
				AudioSource.PlayClipAtPoint(jumpclips,gameObject.transform.position);
				gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f,jumpy));
				//hero.AddForce(new Vector2(0f,1000f));
				jump = false;
				grounded = false;
			}

		}
		Debug.DrawLine (transform.position, groundcheck.transform.position,Color.red,1f);
	}

}
