How to connect two c# scripts and connect varibles?

Questions & Answers

I have attempted to connect a variable from one c# to another and I can’t figure out were I have gone wrong. The premise of my game is to get to a checkpoint before the timer runs out and when you have hit said checkpoint the timer resets, can someone please help? Here is my code;

using UnityEngine;
using System.Collections;

public class onTrigger : MonoBehaviour {

    void OnTriggerExit(Collider other)
    {
        GetComponent<Timer>().m_Time = 5f;
    }

    /*
    IEnumerator Wait()
    {
        yield return new WaitForSeconds(1);
    }
    */
}

public class Timer : MonoBehaviour
{

    public Slider m_Slider;
    public float m_Time;
    public float m_StartTime = 5f;

}

I am trying to share the variable m_Time.
Thank you

I will assume you are not using any design pattern like Factory, Singleton, etc. and are no worried about everything be public on your class. So just to demonstrate, you can do something like this:

public class TriggerManager : MonoBehaviour { //avoid onTrigger as class name, sounds like a Event name

     public Timer myTimer; //field of the class Timer

    void Awake()
    {
          this.myTimer = Find("TimerGameObjectNameHere").GetComponent<Timer>(); //try to find the object
          if (this.myTimer == null) //null check, if there is not a Timer instantiated, create one and assign the reference to the local field
               this.myTimer = new GameObject("TimerGameObjectNameHere").AddComponent<Timer>();
     }

     void OnTriggerExit(Collider other)
     {
         this.myTimer.m_Time = 5f;
     }    
 }

//still the same as yours
public class Timer : MonoBehaviour
 { 
     public Slider m_Slider;
     public float m_Time;
     public float m_StartTime = 5f; 
 }
