Question

以下脚本会对我的敌人预制件造成伤害，但其上方的健康栏与其当前的健康状况不符。它不会对其各自的健康栏进行更改，而只会更改层次结构窗口中预制件的第一个实例。但是，当对敌人施加正确的伤害时，敌人仍会被摧毁。需要注意的是健康栏图像是画布的子画面，画布是主预制件的子画面，并附有脚本。我该如何解决这个问题？

using UnityEngine;
using System.Collections;

public class EnemyHealth : MonoBehaviour {
    private float curHealth = 100f;
    private float GunDamage;
    private GameObject hb;
    private GameObject gd;
    private GameObject canvas;
    public float maxHealth;
    public string gunType;

void Start () {
    canvas = GameObject.Find ("HealthCanvas");
    hb = GameObject.Find ("HealthBar");
    gd = GameObject.Find (gunType);
    GunDamage = gd.GetComponent<Shoot> ().bulletDamage;
}

public void SubtractHealth(float howMuch){
    curHealth = curHealth - howMuch;
    if (curHealth <= 0) {
        Destroy (this.gameObject);
    }

    //Update health bar
    hb.GetComponent<RectTransform>().sizeDelta = new Vector2 (hb.GetComponent<RectTransform>().sizeDelta.x - 0.95f / maxHealth * GunDamage , hb.GetComponent<RectTransform>().sizeDelta.y);
    Debug.Log (curHealth);
    }
}

Answer 1

canvas = this.transform.FindChild ("HealthCanvas").gameObject;
hb = canvas.transform.FindChild ("HealthBar").gameObject;
