Decrease life from another script

Hi all. I have a sciprt which contains player life as a variable. I have another scripts which restores the player to the starting position when the jump button is touched. I would like to put here something which would decrease life by 1 when the button is pushed. Here are the 2 scripts:

Lives.cs:

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

public class Lives : MonoBehaviour {


	public Text lifeText;
	public int lives;



	// Use this for initialization
	void Start () {
		SetCountText();

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

	public void LifeLost(int lifeMinus)
	{
		lives -= lifeMinus;
		SetCountText ();
	}

	void SetCountText(){
		lifeText.text = "Life: " + lives.ToString ();


	}
}

Restore.cs:

using UnityEngine;
using System.Collections;
using UnityStandardAssets.CrossPlatformInput;
using UnityEngine.UI;

public class Restart : MonoBehaviour {

	public GameObject player;
	public GameObject startPos;

	public Text gameOverText;


	

	void Update () {

		if (CrossPlatformInputManager.GetButton ("Jump")) {

			player.transform.position=startPos.transform.position;
			player.SetActive(true);
			gameOverText.text="";
//HERE I SHOULD PUT SOMETHING THAT WOULD REDUCE LIFE BY 1 IN Lives.cs//
		}
	}
}

I would be really greatfull if someone could give me a solution.

Use GetComponent

For instance, declare your script like this at the top of your script:

Lives livesScript;

then in the start function, put:

livesScript = GameObject.Find("Player").GetComponent<Lives>();

now you can access the variables of that player’s lives script like this. (Be sure to make them public variables or it won’t work!)

livesScript.lives -=1; //subtract 1 life
