1、首先创建一个敌人的脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class enemy : MonoBehaviour {
public float Blood = 0;
}
2、将脚本拖拽到游戏对象（以Cube代替敌人）

设置不同的血量
3、编写查找敌人的脚本
public class FindEnemy : MonoBehaviour {
public string childname = "name";
public void OnGUI()
{
if (GUILayout.Button("button"))
{
enemy[] allenemy = Object.FindObjectsOfType<enemy>();
enemy enemyminblood = FindEnemMixBlood(allenemy);
enemyminblood.GetComponent<MeshRenderer>().material.color = Color.red;
}
if (GUILayout.Button("层级未知，查找子物体"))
{
Transform child = FindHelper.GetChild(this.transform, childname);
child.GetComponent<MeshRenderer>().material.color = Color.green;
}
}
public enemy FindEnemMixBlood(enemy[] allenemy)
{
enemy minenemy = allenemy[0];
for (var i = 1; i < allenemy.Length; i++)
{
if (allenemy[i].Blood < minenemy.Blood)
{
minenemy = allenemy[i];
}
}
return minenemy;
}
}
编写层级未知以名字查询物体对象的脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FindHelper {
public static Transform GetChild(Transform parentTF, string childName)
{
Transform child = parentTF.Find(childName);
if (child != null)
return child;
int count = parentTF.childCount;
for (var i = 0; i < count; i++)
{
child = GetChild(parentTF.GetChild(i), childName);
if(child!=null)
return child;
}
return null;
}
}
