Unity创建小地图

一、

二、

新建相机，调节相机俯视场景，挂载脚本（可点击移动）

using UnityEngine;
using System.Collections;
public class mapCam : MonoBehaviour {
    public static mapCam Instance;
    Camera _mapCam;//小地图相机
    GameObject player;//需要移动的物体
    /// <summary>
    /// 小地图的开关
    /// </summary>
    public  bool canSmallMap;
    private bool ifDiMian = true;
    void Awake () {
        Instance = this;
        canSmallMap = true;
        _mapCam=GetComponent<Camera>();//获取相机
        player = GameObject.FindGameObjectWithTag("Player");//获取物体
        //配置点击区域
        //transform.GetChild(0).gameObject.tag = "floor";
        //transform.GetChild(0).GetComponent<MeshRenderer>().enabled = false;
        //transform.GetChild(0).GetComponent<MeshRenderer>().receiveShadows = false;
       // transform.GetChild(0).GetComponent<MeshRenderer>().castShadows = false;
    }
    void Update () 
    {
        if (Input.GetMouseButton(0))
        {
            if (canSmallMap)
            {
                Ray ray = _mapCam.ScreenPointToRay(Input.mousePosition);
                RaycastHit hit;
                if (Physics.Raycast(ray, out hit))
                {
                    StartCoroutine("Wait1S", 0.7f);
                    canSmallMap = false;                                  
                    if (ifDiMian)
                    {
                        if (hit.collider.tag == "floor")
                        {
                            //上 -- 上
                            Vector3 goTo = new Vector3(hit.point.x, 0.8f, hit.point.z);
                            //移动到模型
                            iTween.MoveTo(player, iTween.Hash("position", goTo, "time", 0.01f, "looktarget", goTo, "delay", 0.1f));
                            Debug.Log(1);
                            ifDiMian = true;
                        }
                    }
                    //else
                    //{
                    //    if (hit.collider.tag == "floor")
                    //    {
                    //        //上 --- 下
                    //        //目标位置
                    //        Vector3 goTo = new Vector3(hit.point.x, 0.8f, hit.point.z);
                    //        //移动到模型
                    //        //iTween.MoveTo(player, iTween.Hash("position", goTo, "time", 0.6f, "looktarget", goTo, "delay", 0.1f));
                    //        player.transform.localPosition = goTo;
                    //        Debug.Log(5);
                    //        ifDiMian = true;
                    //    }
                    //}
                    iTween.RotateTo(player, iTween.Hash("x", 0, "y", player.transform.localEulerAngles.y, "z", 0, "time", 0.001f, "delay", 0));
                    Debug.Log(ifDiMian);
                }
            }

    IEnumerator Wait1S(float waitTime)
    {
        yield return new WaitForSeconds(waitTime);
        canSmallMap = true;
    }
