Trigger not triggering

I have a trigger item, the istrigger being on it's box collider, also has arigidbody, and the player, who has a capsule collider, and a rigidbody.

My script that handles the trigger: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityStandardAssets.Characters.FirstPerson;

public class Player : MonoBehaviour { List WildCreatures; List StoredCreatures; List OtherTrainerCreatures; GameObject[] CreaturesInInv; int nextserialnumber; bool inbattle; GameObject SpawnTile; GameObject Player1; GameObject Creature; GameObject Player1Camera; GameObject CreatureCamera; CharacterController Player1Input; CharacterController CreatureInput; // Start is called before the first frame update void Start() { nextserialnumber = 0; inbattle = false; WildCreatures = new List(); StoredCreatures = new List(); OtherTrainerCreatures = new List(); CreaturesInInv = new GameObject[4]; Vector3 spawnPos = transform.position + transform.forward * 2; GameObject Teddy = Instantiate(GameObject.FindGameObjectWithTag("Teddy"), spawnPos, transform.rotation); CreaturesInInv[0] = Teddy; Teddy.active = false; Player1Camera = gameObject.transform.GetChild(0).gameObject; Player1Input = gameObject.GetComponent(); ; }

 // Update is called once per frame
 void Update()
 {

 }

 public static GameObject CreateCreature()
 {
     int Creaturenumber = (int)Random.value;
     if (Creaturenumber == 0)
     {
         GameObject[] PossibleCreatures = GameObject.FindGameObjectsWithTag("Teddy");
         for (int i = 0; i < PossibleCreatures.Length; i++)
         {
             if (PossibleCreatures[i].transform.position.y < 0)
             {
                 return PossibleCreatures[i];
             }
         }
     }
     return GameObject.FindGameObjectWithTag("Teddy");
 }

 public void OnTriggerEnter(Collider other)
 {
     Debug.Log(inbattle);
     if (inbattle == false)
     {
         Vector3 placetospawn = transform.position + transform.forward * 10;
         placetospawn.y = (float)0.3;
         GameObject newcreature = Instantiate(CreateCreature(), placetospawn, Quaternion.Euler(0, transform.rotation.y * 100 + 180, 0));
         WildCreatures.Add(newcreature);
         WildBattle(gameObject, newcreature);
         other.gameObject.GetComponent<SpawnBlock>().Move();
     }
 }

 public void WildBattle(GameObject Player, GameObject WildCreature)
 {
     inbattle = true;
     Player1 = gameObject;
     Creature = CreaturesInInv[0];
     Creature.active = true;
     Creature.transform.position = transform.position + transform.forward * 4;
     Creature.transform.position = new Vector3(Creature.transform.position.x, (float)0.3, Creature.transform.position.z);
     CreatureCamera = Creature.transform.GetChild(0).gameObject;
     CreatureInput = Creature.GetComponent<CharacterController>();
     CreatureCamera.active = true;
     CreatureInput.enabled = true;
     Player1Camera.active = false;
     Player1Input.enabled = false;
 }

}
