命中条不会完全填满，计算仅发生一次

Question

我有一个击点栏，每次球对象与goodOrb对象碰撞时，该点都应填充0.1。但是，只有在第一次碰撞时，横条才会填充0.1。当球再次碰撞时，它不会移动。

我尝试了Debug.Log，它记录了变量hitPoints的值，该值存储了填充条的当前数量。此变量初始化为0，每当两个对象发生碰撞时，我都应该将另一个变量称为增加，将其设置为0.1，将增加变量添加到生命值。但这仅发生一次。 Debug.Log（hitpoints）仅显示一次0.1。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;


public class goodOrb : MonoBehaviour
{

    public int maxHealth = 100;
    public int currentHealth;
    public Image barImage;
    private Rigidbody2D rb;
     public float increase = 0.1f; //amount to increase bar each time a collision happens

    public float hitPoints = 0.0f; // current amount the bar is filled by

          //  public AudioSource collisionSound;
    int scoreValue= 5 ;
    // Start is called before the first frame update
    public void Start()
    {
            GameObject Filler = GameObject.Find("Filler");

            Image barImage = Filler.GetComponent<Image>();


    }

void OnTriggerEnter2D(Collider2D other)
    {  

        ParticleSystem ps = GetComponent<ParticleSystem>();    

        if(other.tag=="Ball")
        {        
             ps.Play(); 
             HitPoints();
             scoreManager.score += scoreValue; 
             // barImage.fillAmount = (float)currentHealth / (float)maxHealth;

           // collisionSound.Play();
        }



    }

    void Update()

    {


    }

    // Update is called once per frame
    void HitPoints()
    {

               GameObject Filler = GameObject.Find("Filler");

            Image barImage = Filler.GetComponent<Image>();

            hitPoints = hitPoints + increase;
                barImage.fillAmount = hitPoints;
             //print(hitPoints);
             Debug.Log(hitPoints);


    }


}

我希望每次发生碰撞并填充填充点时，都会增加填充量。

Answer 1

1-确保每次球都与相同的球体碰撞。2-确保一个对撞机isTrigger为true。3-确保每次球碰撞时调用触发功能。通过做这个

void OnTriggerEnter2D(Collider2D other){
        Debug.Log (other.tag);
}
