Question by $$anonymous$$ · Apr 01, 2019 at 05:54 PM · findfindgameobjectswithtagfindwithtag

How to hit a specific object

Hi.

I want the tag to work as the tag.

When I shoot the - only falls the one which i touched.

But the tag objects fall together. When i touch balloon's karzina, i want the gravityScale to be changed.

Thanks in advance.

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

 public class Arrow_1 : MonoBehaviour {
 
     public float speed;
     public float lifeTime;
     public float distance;
     public int damage;
     public LayerMask whatIsSolid;
 
     GameObject[] karzina;
     
     
     
     
 
 
     void Start () {
         
         Invoke("DestroyArrow_1", lifeTime);    
     }
     
     void Update () {
         Vector2 screenPosition = Camera.main.WorldToScreenPoint(transform.position);
         if (screenPosition.y > Screen.height  || screenPosition.y < 0)
     {
         Destroy(gameObject);
     
     }
         RaycastHit2D hitInfo = Physics2D.Raycast(transform.position, transform.up, distance, whatIsSolid);
         if (hitInfo.collider != null) {
             if (hitInfo.collider.CompareTag("Balloon")) {
                 hitInfo.collider.GetComponent<Balloon>().TakeDamage(damage);
             }
     
         
         Destroy(gameObject);
             karzina=GameObject.FindGameObjectsWithTag("karzina");
 
             foreach (GameObject r in karzina){
 
             r.GetComponent<Rigidbody2D>().gravityScale = 2f; 
                 
         }
         
             
         }
 
         transform.Translate(Vector2.up * speed * Time.deltaTime * 1.5f);
     }
 
     
 }

Change your update method to this one

 void Update () {
          Vector2 screenPosition = Camera.main.WorldToScreenPoint(transform.position);
          if (screenPosition.y > Screen.height  || screenPosition.y < 0)
      {
          Destroy(gameObject);
      
      }
          RaycastHit2D hitInfo = Physics2D.Raycast(transform.position, transform.up, distance, whatIsSolid);
          if (hitInfo.collider != null) {
              if (hitInfo.collider.CompareTag("Balloon")) {
                  hitInfo.collider.GetComponent<Balloon>().TakeDamage(damage);
                 hitInfo.collider.gameObject.transform.GetChild(0).GetComponent<Rigidbody2D>().gravityScale = 2f;
              }
                 
          Destroy(gameObject);
                       
          }
  
          transform.Translate(Vector2.up * speed * Time.deltaTime * 1.5f);
      }
