using UnityEngine;

using System.Collections;

public class Follow3DObject : MonoBehaviour

{

    public Transform target;

    public Vector3 offset = new Vector3(0, 1, 0);

    void Update()

    {

        if (target != null)

        {

            transform.position = Camera.main.WorldToScreenPoint(target.position + offset);

        }

    }

}

这种方法是通过把脚本绑定在血条（血条需要自己制作，显示血量什么的在下面）上，然后把怪物目标拖到这里的target上。

转换一下就可以把脚本绑定在怪物身上，同时达成只有战斗时才触发！

using UnityEngine;

using UnityEngine.UI;

public class ShowBlood : MonoBehaviour

{

    public Image frame;

    public Image imageBlood;

    public Vector3 offset = new Vector3(0, 1, 0);

    void Update()

    {

        if (this.GetComponent<ArmyMove>().isBattle)

        {

            frame.gameObject.SetActive(true);

            frame.transform.position = Camera.main.WorldToScreenPoint(transform.position + offset);

            float blood = GetComponent<AbStatus>().Blood;

            float maxBlood = GetComponent<AbStatus>().MaxBlood;

            imageBlood.fillAmount = blood / maxBlood;

        }

        else {

            frame.gameObject.SetActive(false);

        }

    }

}

提示：如果UGUI设置阻挡后，血条显示会阻挡正常游戏，请在血条的image里把Raycast Target点掉，就好了
