贪吃蛇方案

这里只给点思路。没有完整的做出效果来

创建头 Head（一个立方体）绑定senk.cs脚本

senk.cs代码

using UnityEngine;
using System.Collections;


//蛇头移动代码
public class senk : MonoBehaviour
{

    float timeer;
    float timeOff;


    public BodyFolloyw next;


    Vector3 originPositon; //蛇头移动前的位置

    public GameObject Prefab;


    BodyFolloyw tail;

    // Use this for initialization
    void Start()
    {
        timeer = 0;
        timeOff = 1;
    }

    // Update is called once per frame
    void Update()
    {
        Move();
        Turn();
        AddTail();


    }

    /// <summary>
    /// 移动
    /// </summary>
    void Move()
    {
        timeer += Time.deltaTime;
        if (timeer > timeOff)
        {
            originPositon = transform.position;
            transform.Translate(Vector3.forward);
            timeer = 0;

            if (next)
            {
                next.Follow(originPositon);
            }
        }

    }

    /// <summary>
    /// 拐弯
    /// </summary>
    void Turn()
    {
        if (Input.GetKeyDown(KeyCode.A))
        {
            transform.Rotate(Vector3.up * -90);
        }
        if (Input.GetKeyDown(KeyCode.D))
        {
            transform.Rotate(Vector3.up * 90);
        }
    }
    BodyFolloyw body;
    void AddTail()
    {
        if (Input.GetMouseButtonDown(0))
        {
            body = ((GameObject)Instantiate(Prefab, Vector3.one * 999, Quaternion.identity)).GetComponent<BodyFolloyw>();

            if (!next) //第一个身体产生的时候
            {
                next = body;
                tail = next;
            }
            else
            {
                tail.next = body;
                tail = tail.next;
            }
        }
    }
}

创建一个预设体body1，赋值给senk.cs脚步中的public GameObject Prefab;作为蛇的身体

然后body1预设体绑定脚本BodyFolloyw.cs

BodyFolloyw.cs代码

using UnityEngine;
using System.Collections;


//蛇的其他部位移动
public class BodyFolloyw : MonoBehaviour
{

    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }

    public BodyFolloyw next;

    Vector3 originposition;

    public void Follow(Vector3 position)
    {
        originposition = transform.position;

        transform.position = position;

        if (next)
        {
            next.Follow(originposition);
        }
    }
}

好了。这样就实现了。鼠标左键单击。就会增加一个身体。基本思路这样。有时间在完成一个成品吧。现在太累了。唉！！
