Question by Jdawg20072 · Jan 18, 2020 at 04:17 AM · 3dfpsball

i'm new to unity. I want to make a script that creates and throws a ball. You can't throw the ball again until you pick it up. My throwing part works but the pick up action doesn't

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PickUpObject : MonoBehaviour
 {
     GameObject prefab;
     public GameObject prefab2;
     public bool ballThrown = false; 
 
     void Start()
     {
         prefab = Resources.Load("projectile") as GameObject;
         
     }
 
      void Update()
     {
         if(Input.GetMouseButtonDown(0))
         {
             if (ballThrown == false)
             {
                 GameObject projectile = Instantiate(prefab) as GameObject;
                 projectile.transform.position = transform.position + Camera.main.transform.forward * 2;
                 Rigidbody rb = projectile.GetComponent<Rigidbody>();
                 rb.velocity = Camera.main.transform.forward * 40;
                 ballThrown = true;
             }
 
             if(ballThrown == true)
             {
 
             }
         }
 
 
     }
 
     void OnCollisionStay(Collision node)
     {
         if (node.gameObject.tag == "ball")
         {
             ballThrown = false;
             Destroy(node.gameObject);
         }
     }
 
 }

Rather than use a prefab and instantiate you should just make a public GameObject variable and assign it your ball in the inspector, then instead of destroying it you pick it back up.
