Как сделать восполнение голода в юнити?

Скрипт голода:

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

public class Hungry : MonoBehaviour {
public float currentHungry = 100;
public float time = 1f;

private float minHungry = 0;
private float maxHungry = 100;


Slider slider;

void Start () {
slider = GetComponent<Slider>();
slider.interactable = false;
StartCoroutine(hungry(2));
}

void Update () {

}

IEnumerator hungry(float h) {
while (currentHungry >= minHungry){
yield return new WaitForSeconds(time);
currentHungry -= h;
slider.value = currentHungry;
}
}
}

Скрипт взятия предметов:

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

public class PickUpWeapon : MonoBehaviour
{

public GameObject camera;
public float distance = 15f;
GameObject currentWeapon;
bool canPickUp = false;



void Update()
{
if (Input.GetKeyDown(KeyCode.E)) PickUp();
if (Input.GetKeyDown(KeyCode.Q)) Drop();
}

void PickUp()
{
RaycastHit hit;
if(Physics.Raycast(camera.transform.position, camera.transform.forward, out hit, distance))
{
if(hit.transform.tag == "Weapon")
{
if (canPickUp) Drop();

currentWeapon = hit.transform.gameObject;
currentWeapon.GetComponent<Rigidbody>().isKinematic = true;
currentWeapon.GetComponent<Collider>().isTrigger = true;
currentWeapon.transform.parent = transform;
currentWeapon.transform.localPosition = Vector3.zero ;
currentWeapon.transform.localEulerAngles = new Vector3(10f, 0f, 0f);
canPickUp = true;
}
}


}

void Drop()
{
currentWeapon.transform.parent = null;
currentWeapon.GetComponent<Rigidbody>().isKinematic = false;
currentWeapon.GetComponent<Collider>().isTrigger = false;
canPickUp = false;
currentWeapon = null;
}

}

Мне нужно, чтобы когда предмет еды взят, при нажатии клавиши F сам предмет удаляется, и добавляет к переменной currentHungry += 25
