Unity 爱心血量效果

1.准备爱心血条

准备好红色爱心和灰色爱心的图片

2.HeartUI 代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Hearts : MonoBehaviour {
    [Header("爱心UI图的列表")]public List<Image> redHearts = new();

    void Start () 
    {

    }

    public void UpdateHeartUI(int HP)
    {
        //先将所有红色爱心全部隐藏
        foreach (Image redHeart in redHearts)
        {
            redHeart.enabled = false;
        }
        //再根据HP数量先将爱心依次显示
        for (int i=0; i< HP; i++)
        {
            redHearts[i].enabled = true;
        }
    }   
}

3.在Inspector窗口中绑定好对象

4.在血量减少的地方，调用更新方法
