一、准备工程项目

二、新建脚本

1.新建test脚本挂在BG上

using UnityEngine;
using UnityEngine.UI;

namespace HKZ

    public class Test : MonoBehaviour
    
        public static Test Instance;
        private Image imgRed;
        private Image imgYellow;
        private float currentPrg = 1f;
        private float targetPrg = 1f;

        public float AccelerHpSpeed = 0.5f;//渐变速度

        private void Start()
        
            Instance = this;
            imgRed = transform.Find("imgRed").GetComponent<Image>();
            imgYellow = transform.Find("imgYellow").GetComponent<Image>();
            imgRed.fillAmount = 1;
            imgYellow.fillAmount = 1;
        

        private void Update()
        
            BlendHp();
            imgYellow.fillAmount = currentPrg;
        

        public void SetHpVal(int oldVal, int newVal, int sum)
        
            currentPrg = oldVal * 1.0f / sum;
            targetPrg = newVal * 1.0f / sum;
            imgRed.fillAmount = targetPrg;
        

        private void BlendHp()
        
            if (Mathf.Abs(currentPrg - targetPrg) < AccelerHpSpeed * Time.deltaTime)
            
                currentPrg = targetPrg;
            
            else if (currentPrg > targetPrg)
            
                currentPrg -= AccelerHpSpeed * Time.deltaTime;
            
            else
            
                currentPrg += AccelerHpSpeed * Time.deltaTime;
            
        
    

2.新建Player脚本挂在Player上

代码如下（示例）：

using UnityEngine;

namespace HKZ

    public class Player : MonoBehaviour
    
        private int hp = 1000;
        private int oldHp;
        private int newHp;
        private int hurt = 300;

        private void Start()
        
            oldHp = hp;
        

        private void Update()
        
            if (Input.GetMouseButtonDown(0))
            
                newHp = oldHp - hurt;
                Test.Instance.SetHpVal(oldHp, newHp, hp);
                oldHp = newHp;
