任务：战斗系统之击败怪物与怪物UI血条信息

    void Start(){
        var enemyObj = GameObject.FindGameObjectWithTag("Enemy");
        enemy = enemyObj.GetComponent<Enemy>();
        health1 = GameObject.Find("H/Slider3").GetComponent<Slider>();
    }
    void Update(){
        if (health1 != null)
            health1.value = enemy.Hp;
    }
}

using UnityEngine;
public class Cage : MonoBehaviour{
    private GameObject uiPrefabInstance; //敌人信息实例化UI
    void OnTriggerEnter(Collider other){
        Debug.Log("角色进入牢笼");
        if (other.CompareTag("Player")){
            GameObject prefab = Resources.Load<GameObject>("Prefabs/Panel/Package/EnemyInfo");
            uiPrefabInstance = Instantiate(prefab, new Vector3(0f, -100, 0f), Quaternion.identity);
            uiPrefabInstance.transform.SetParent(GameObject.Find("Canvas").transform, false);
        }
    }
    private void OnTriggerExit(Collider other){
        if (other.CompareTag("Player"))
            GameObject.Find("EnemyInfo(Clone)").gameObject.SetActive(false);
    }
}

实现效果：

进入牢笼后，

退出牢笼后，

击打怪物，

当血量减为0，

离开牢笼，

End.
