不知道如何获得敌人的健康 [英] Don't know how to get enemy's health

问题描述

我有这段代码，我不知道为什么hit.collider.gameObject.GetComponent("health")返回空值

I have this code and I don't know why hit.collider.gameObject.GetComponent("health") is returning null

void Shoot() {
        Vector2 mousePosition = new Vector2 (Camera.main.ScreenToWorldPoint (Input.mousePosition).x, Camera.main.ScreenToWorldPoint (Input.mousePosition).y);
        Vector2 firePointPosition = new Vector2 (firePoint.position.x, firePoint.position.y);
        RaycastHit2D hit = Physics2D.Raycast (firePointPosition, mousePosition - firePointPosition, bulletRange, whatToHit);
        if (Time.time >= timeToSpawnEffect) {
            Effect ();
            timeToSpawnEffect = Time.time + 1/effectSpawnRate;
        }

        if (hit.collider != null) {
            if (hit.collider.name == "Enemy") {
                Debug.Log(hit.collider.gameObject.GetComponent("health"));
            }
            //Debug.Log("We hit " + hit.collider.name + " and did " + damage + " damage");
        }

    }

这是我的敌人剧本

using UnityEngine;
using System.Collections;

public class EnemyAI : MonoBehaviour
{

    public float health = 100f;
    //... rest of the code
}

推荐答案

您需要获得对附加到敌人的脚本的引用.然后使用该脚本来控制运行状况.

You need to get a reference to the script attached to the Enemy. Then use that script to manipulate the health.

找到GameObject.

Find the GameObject.

 GameObject g = hit.collider.gameObject;

获取对脚本的引用.

 EnemyAI e = g.GetComponent<EnemyAI>();

控制健康.

 e.health = 0f;

如果想成为坏蛋，请一行.

In one line if you want to be badass.

 hit.collider.gameObject.GetComponent<EnemyAI>().health = 0.0f;

---

奖金提示:health应该是private，而EnemyAI应该具有该变量的设置器和获取器.

---

Bonus tip: health should be private and EnemyAI should have a setter and a getter for that variable.
