Coins and Enemies 3d

My player, when colliding with an enemy dies, which is correct but when it collides with a coin it still dies T_T
Here is the script for the PlayerMotor:

using UnityEngine;
using System.Collections;

public class PlayerMotor : MonoBehaviour
{

private CharacterController controller;
private Vector3 moveVector;
private float speed = 5.0f;
private float verticalVelocity = 0.0f;
private float gravity = 20.0f;
private float animationDuration = 3.0f;
private bool isDead = false;
private float startTime;
private Transform cointrans;

// Use this for initialization
void Start()
{

    controller = GetComponent<CharacterController>();
    startTime = Time.time;
}

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

    if (isDead)
        return;

    if (Time.time-startTime < animationDuration)
    {
        controller.Move(Vector3.forward * speed * Time.deltaTime);
        return;
    }

    moveVector = Vector3.zero;

    if (controller.isGrounded)
    {
        verticalVelocity = -0.5f;
    }

    else
    {
        verticalVelocity -= gravity * Time.deltaTime;

    }

    //X - left and right
    //moveVector.x = Input.GetAxisRaw("Horizontal") * speed;
    //Rect bounds = new Rect(0, 0, Screen.height / 2, Screen.width);
   //if (Input.GetMouseButtonDown(0) && bounds.Contains(Input.mousePosition))
        if (Input.GetMouseButton(0))
    {
        //are we holding click on the right side
        if (Input.mousePosition.x > Screen.width / 2)
            moveVector.x = speed;
        else
            moveVector.x = -speed;
    }

    //Y - up and down
    moveVector.y = verticalVelocity;

    //Z - forward and backward
    moveVector.z = speed;
    controller.Move(moveVector * Time.deltaTime);

}

public void SetSpeed(float modifier)
{
    speed = 8.0f + modifier;
}



//It is being called everytime out capsule hits something
private void OnControllerColliderHit(ControllerColliderHit hit)
{
    //if (GameObject.FindWithTag("Enemy") == null)
    //cointrans = GameObject.FindGameObjectWithTag("Coin").transform;
    if (hit.point.z >= transform.position.z + controller.radius && GameObject.FindWithTag("Enemy") == null)
        Death();
    else
        CoinScore();
}

private void Death()
{
    isDead = true;
    GetComponent<Score>().OnDeath();
   // GetComponent<CoinBehavior>().OnTriggerEnter();
}

private void CoinScore()
{
    isDead = false;
    GetComponent<PickUpScript>().CoinScores();
}

}

and this is for the coin

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class PickUpScript : MonoBehaviour
{
public Text coinText;
public float coin;
public DeathMenu deathMenu;

void Update()
{
    transform.Rotate(Vector3.up, Time.deltaTime * rotateSpeed);
}

public void OnTriggerEnter(Collider col)
{
    // UIManager.Instance.IncreaseScore(ScorePoints);
    PlayerPrefs.SetFloat("Banana Milk: ", coin);
    Destroy(this.gameObject);

}

public void CoinScores()
{
    
    if (PlayerPrefs.GetFloat("Highscore") < coin)
    {
        //PlayerPrefs.SetFloat("Highscore", score);
        PlayerPrefs.SetFloat("Banana Milk: ", coin);
    }
    //PlayerPrefs.SetFloat("Banana Milk: ", coin);
    //  Debug.Log();
     deathMenu.ToggleEndMenu(coin);
}

public int ScorePoints = 100;
public float rotateSpeed = 50f;

}

Are you using tags? If you are i think you have tagged the coin and enemy with the same name.

check the inspector of your gameobject78513-screenshot-1.jpg
