Collision Not Responding

Hello i am making a C Road Puzzle Game and i have Player Movement Code[C#] here is my code

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

public class Bounce : MonoBehaviour {

 public Swipe swipeControls;

 public GameObject key;

 float lerpTime ;
 float currentLerpTime;
 float perc = 1;

 Vector3 startPos;
 Vector3 endPos;

 bool FirstInput;
 public bool justJump;

 void Update ()
 {
     if(swipeControls.SwipeLeft || swipeControls.SwipeRight || swipeControls.SwipeUp || swipeControls.SwipeDown)
     {
         if(perc == 1)
         {
             lerpTime = 1;
             currentLerpTime = 0;
             FirstInput = true;
             justJump = true;
         }
     }

     startPos = gameObject.transform.position;
     if (swipeControls.SwipeRight && gameObject.transform.position == endPos) 
     {
         endPos = new Vector3(transform.position.x + 1, transform.position.y, transform.position.z);
     }
     if (swipeControls.SwipeLeft && gameObject.transform.position == endPos)
     {
         endPos = new Vector3(transform.position.x - 1, transform.position.y, transform.position.z);
     }
     if (swipeControls.SwipeUp && gameObject.transform.position == endPos)
     {
         endPos = new Vector3(transform.position.x, transform.position.y, transform.position.z + 1);
     }
     if (swipeControls.SwipeDown && gameObject.transform.position == endPos)
     {
         endPos = new Vector3(transform.position.x, transform.position.y, transform.position.z - 1);
     }

     if (FirstInput == true)
     {
         currentLerpTime += Time.deltaTime * 5;
         perc = currentLerpTime / lerpTime;
         gameObject.transform.position = Vector3.Lerp(startPos, endPos, perc);
     }
     if(perc > 0.8)
     {
         perc = 1;
     }

     if (Mathf.Round(perc) == 1)
     {
         justJump = false;
     }
 }

 void OnTriggerEnter(Collider myTrigger)
 {
     if(myTrigger.gameObject.name == "Enemy")
     {
         key.SetActive(false);
     }
 }

}

The Problem is that my Player cant Collide with other objects it can only collide using Rigid Body which i do not want in my game,Can someone EDIT my code so Character Controller will be needed so it can collide.Please i am no expert by the way this is my 2nd game.
