how to reset timer when score hits an increment of 50

say you have a score script that keeps score
using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class Score : MonoBehaviour 
{
	public Text scoreGUI;
	public int scoreCounter;


	// Use this for initialization
	void Awake () 
	{
		scoreGUI = GetComponent <Text> ();
		scoreCounter = 0;
	}
	
	// Update is called once per frame
	void Update () 
	{
		scoreGUI.text = "Score: " + scoreCounter;
	}


}

(currents in another Script i have the script so it adds a point every time a certain object is clicked, so that works)

Before i go on, here is my timer script. it counts down from 10 to 0 and on 0 it will stop counting down and it will end the game

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

public class TimerGUI : MonoBehaviour 
{
	public Text timerGUI;
	public int timer;
	
	// Use this for initialization
	void Awake () 
	{
		timerGUI = GetComponent <Text> ();
		timer = 0;
	}
	
	// Update is called once per frame
	void Update () 
	{
		if (timer > 0) 
		{
			timer -= Time.deltaTime;
		}

		if (timer = 0) 
		{
			//lose game.
		}

		timerGUI.text = "Time Left: " + timer;
	}
}

What ive been trying to do is figure out how i can have the timer reset to 10 every time the scoreCounter reaches an increment of 50 (50,100,150, and so on)
but i cant figure out how. i know how to do it say if it would hit 50

if (score.scoreCounter = 50)
{
timer = 0;
}

but i cant figure out how to make it reset like that every time the score hits an increment of 50.

Help would be appreciated, thanks!

I have answered pretty much the same question some time ago, here is it.

Also don’t forget to provide your instance of your Score script to TimerGUI or vice versa (depending where you will check your condition).

Alternatively you can make your scoreCounter or timer as a static variable (again depending where you will check your condition).
