进度条

主要内容:实现点击物体后,销毁物体,记录销毁数量,进度条做出相应改变(如下图)

 面板与代码如下:

using System.Collections;

using UnityEngine;
using UnityEngine.UI;

public class ChangeValue : MonoBehaviour
{
    Text text ;
    int a = 0;
    Image amount;
    GameObject cubes;

    // Start is called before the first frame update
    void Start()
    {
        text = transform.Find("Text").GetComponent<Text>();
        text.text = a + "";
        amount = transform.Find("Blood/BloodValue").GetComponent<Image>();
        amount.fillAmount = 0;
        cubes = GameObject.Find("GameObject");
    }


    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButton(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitInfo;
            if (Physics.Raycast(ray, out hitInfo))
            {
                Destroy(hitInfo.transform.gameObject);
                text.text = ++a +"";
                amount.fillAmount = amount.fillAmount + ((1.0f / cubes.GetComponentsInChildren<Transform>().Length));

            }
        }
    }
}

代码解释:利用射线检测获取物体信息。
