How to recycle obstacles in an Endless Runner?

Question

Hi I am creating an Endless Runner for Android, the problem is that obstacles slow down my game, so I don't know how to get them to recycle since they are created infinitely, and another problem is that they are not destroyed by leaving them behind.

This is my code to randomly generate:

 using System.Collections;
 using UnityEngine;
 
 public class GenerateCube : MonoBehaviour
 {
     public GameObject CubeObj;
     Vector3 Pos;
     bool next;
     public float[] posX;
     public float[] posZ;
     int value = 1;
     public int lastpos = 1;
 
     void FixedUpdate(){
         next = true;
         Generate ();
     }
     void Generate(){
         if (!next)
             return;
         int i = Random.Range (0, 3);
         Pos.x = posX[i];
         Pos.z += posZ[i];
         GameObject CubeClone = Instantiate(CubeObj, Pos, CubeObj.transform.rotation);
         CubeClone.GetComponent<CubeScript>().myNum = value;
         CubeClone.transform.SetParent (this.transform);
             value += 1;
         next = false;
         return;
     }
     public void Message(int i){
          if(lastpos == i) {
             lastpos += 1;
             
         }
     }
 }

I hope you can help me, Thanks!

Hi. As I can see, your character runs on axis z+. So, you can attach a script to the obstacle prefab and create a public Transform playerPos and assign the player Transform to that empty slot. In that script add an update function: void Update(){if (transform.position.z < playerPos - 5(over here you put an offset: for example, you don't want to destroy an object when it is exactly behing the player, you want to destroy the object when it is at a certain distance behind the player and out of the camera view. I put 5 just for example, but you should put what you want) Destroy(this.gameObject);)} You can also implement object-pooling, which means that you don't instantiate and destroy objects, you activate and deactivate the same objects.
