Pickup & Drop Objects + Spawn items HELP

Hello

I have multiple problems with my scripts.

Let me explain you what I want to do:

• I have some prefabs from the Free Food Pack that I want them to be spawned when you enter a specific location. I want to spawn only one item at a time and not spawn another until i take the item from the spawnpoint no matter i enter the location. I managed to do it but Instead of spawning an item at a time there are 2 items spawning at a time and when i reenter the location there spawn another two items.

  • I want to pick up and drop down an item and i want to be able to hold one item at a time (I have like 10 prefabs).

  I managed to do it but i have some problems with it

  • When an item is spawned I want to pass a script to it so that I can pass the parameters that are associated with the pickable script (pick up drop down items)

  I managed to do it but I have some problems with it

Triggerspawn Script

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

public class TriggerSpawn : MonoBehaviour {

 public Transform Spawnpoint;
 public GameObject Prefab;
 private bool spawned = false;
 private GameObject PrefabInstance;
 private GameObject TempParent;
 private GameObject breaditem;
 private Pickable pickable;

 void Update()
 {
     pickable = GameObject.FindObjectOfType<Pickable>();
 }

 // Use this for initialization
 void OnTriggerEnter () {
     if (spawned == false) {
         Instantiate(Prefab, Spawnpoint.position, Spawnpoint.rotation);
         PrefabInstance = Instantiate(Prefab, Spawnpoint.position, Spawnpoint.rotation);
         PrefabInstance.AddComponent<Pickable>();
         TempParent = GameObject.Find("Player1/Destination");
         Debug.Log(TempParent);
         breaditem = GameObject.Find("Bread(Clone)");
         Debug.Log(breaditem);
         pickable.item = breaditem;
         pickable.tempParent = TempParent;
         pickable.guide = TempParent.transform;
         spawned = true;
     }
 }

}

Pickable Script

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

public class Pickable : MonoBehaviour {

 public GameObject item;
 public GameObject tempParent;
 public Transform guide;
 bool carrying;
 public float range = 5;

 // Use this for initialization
 //void Start()
 //{
 //    item.GetComponent<Rigidbody>().useGravity = true;
 //}
 // Update is called once per frame
 void Update()
 {
     if (carrying == false)
     {
         if (Input.GetKeyDown(KeyCode.K) && (guide.transform.position - transform.position).sqrMagnitude < range / (15 * range))
         {
             pickup();
             carrying = true;
         }
     }
     else if (carrying == true)
     {
         if (Input.GetKeyDown(KeyCode.K))
         {
             drop();
             carrying = false;
         }
     }
 }
 void pickup()
 {
     item.GetComponent<Rigidbody>().useGravity = false;
     item.GetComponent<Rigidbody>().isKinematic = true;
     item.transform.position = guide.transform.position;
     item.transform.rotation = guide.transform.rotation;
     item.transform.parent = tempParent.transform;
 }
 void drop()
 {
     item.GetComponent<Rigidbody>().useGravity = true;
     item.GetComponent<Rigidbody>().isKinematic = false;
     item.transform.parent = null;
     item.transform.position = guide.transform.position;
 }

}

So what are the problems practically:

• First I enter the point that makes the item spawn and three things appear on the console (1.PNG) the parameters are not passed to the Pickable Script and two prefabs appear

• Then I reenter the spawnpoint and those three things reappear and there spawn two more prefabs with one of those 4 appeared that passes the parameters to the Pickable Script and I can pick it up

It is the first time I upload a question to unity forum and I am new to Unity. So please don't judge me if I made a newbie mistakes and write a comment below If i can provide you with more information or something I forgot to mention in my Post

Thank You
