Endless Runner Code

Ok so I'm making an endless runner and I need it to instantiate the next part of the track every time the player reaches a "Marker" object. The collisions work and the next track section instantiates for the first marker. The position the track is created is based on an object that is a child of the marker (which is also part of the track prefab). My problem is that the 2nd section of track does not get instantiated and I do not believe the collisions are working properly either (The debug I have running does not show anything for the second marker). I also changed the speed of the player to make sure that wasn't a problem.

Here's the code:

 using UnityEngine;
 using System.Collections;
 
 public class MarkerCollisionCheck : MonoBehaviour {
     
     public GameObject objectToSpawn = null;
     //public GameObject spawnPoint = null;
     public bool spawning = false;
 
     void OnTriggerEnter(Collider other)
     {
         if(other.tag == "Player" && spawning == false)
         {
             spawning = true;
             Debug.Log (spawning);
 
             //Instantiate(objectToSpawn, spawnPoint.transform.Find("GroundSpawnPoint").position, Quaternion.identity);
             Instantiate(objectToSpawn, transform.FindChild("GroundSpawnPoint").position, Quaternion.identity);
 
             spawning = false;
         }
     }
 }

So what could be wrong? If you have any questions just ask :D

Thank You, expat1999

So have you debugged if the trigger happens or not ?

 void OnTriggerEnter(Collider other)
 {
     Debug.Log (other);
     Debug.Log (other.tag);
     Debug.Log (spawning);
 
     if(other.tag == "Player" && spawning == false)
     {

Also, if you are not using multithreading, your variable spawning is not needed.

Thank you! While I may have not been very thorough when trying to figure this out for myself I definitely will remember that in the future.

It turns out the "spawning" variable (which I accidentally left in there for a now obsolete script) was always true when the prefabs were spawned. I am still not sure why that is but getting rid of the variable fixed the original problem.

Thank You: expat1999
