Unity_宠物跟随效果_058

下面的案例是实现宠物跟随的效果
下面的代码是角色移动的脚本

using UnityEngine;
using System.Collections;

public class PlayerMove : MonoBehaviour 
{
    // Update is called once per frame
    void Update () {
        //按W键 前进
        if (Input.GetKey(KeyCode.W))
        {
            transform.position += transform.forward * 1 * Time.deltaTime;
        }
        //按S键 后退
        if (Input.GetKey(KeyCode.S))
        {
            transform.position += transform.forward * -1 * Time.deltaTime;
        }
        //按A键 向左旋转
        if (Input.GetKey(KeyCode.A))
        {
            transform.Rotate(transform.up, -30 * Time.deltaTime);
        }
        //按D键 向右旋转
        if (Input.GetKey(KeyCode.D))
        {
            transform.Rotate(transform.up, -30 * Time.deltaTime);
        }
    }
}

以下是宠物绑定的脚本

using UnityEngine;
using System.Collections;

public class Follow : MonoBehaviour {

    public Transform target;
    public Vector3 offset;
    //向后的距离
    public float backDistance = 2;

    //高度
    public float topDistance = 2;

    //在LateUpdate中进行物理
    void LateUpdate()
    {
        //设置偏移量
        offset = -target.forward * backDistance + target.up * topDistance;
        //使用插值，让宠物有一个平滑的移动
        transform.position = Vector3.Lerp(transform.position, target.position + offset,Time.deltaTime);
        //宠物的旋转和玩家的旋转保持一致
        transform.rotation = target.rotation;
    }
}
