Problem with trigger

I think if you touch the cube, the cube will chase you. That's what I think your question is. Put this to the cube but it will chase you even without triggering. Make the cube into an enemy tag and your player into player tag first before inserting this.

 using UnityEngine;
 using System.Collections;
 
 public class EnemyAI : MonoBehaviour {
     public Transform target;
     public int moveSpeed;
     public int rotationSpeed;
     public int maxDistance;
     
     private Transform myTransform;
     
     void Awake() {
         myTransform = transform;
         target = null;
     }
     
     // Use this for initialization
  IEnumerator Start () {
        yield return new WaitForSeconds(10);
        GameObject go = GameObject.FindGameObjectWithTag("Player");
 
        target = go.transform;
 
        maxDistance = 1;
     }
     
     // Update is called once per frame
     void Update () {
         if(target == null) {
             return;
         }
         Debug.DrawLine(target.position, myTransform.position, Color.yellow);
         
         //Look at target
         myTransform.rotation = Quaternion.Slerp (myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed * Time.deltaTime);
         
         if(Vector3.Distance(target.position, myTransform.position) > maxDistance) {
         //Move towards target
         myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
         }
     }
 }
