问题描述

通过GetComponent<>()获取Slider报错

ArgumentException: GetComponent requires that the requested component ‘Slider’ derives from MonoBehaviour or Component or is an interface.

using Tools;
using UI.Base;
using UnityEngine;
using UnityEngine.UIElements;

namespace UI {
    public class MainUI : MonoBehaviour{
        [Header("子界面")]
        [SerializeField]private GameObject HPSlider;
        private Slider slider;
        private new void Start() {
            slider = HPSlider.GetComponent<Slider>();
        }

        private void UpdateHp(Message message) {
                slider.value = (float)message.Body;
        }
    }
}
