Questions & Answers
1

essentially i want to push space bar and change the variable to true so that the log will say some the first string.

using UnityEngine;
using System.Collections;

public class LearningScript2 : MonoBehaviour 
{




	// Use this for initialization
	void Start () 
	{
		bool boss = false;
		//int temperature = 40;

		if(Input.GetKeyUp(KeyCode.Space))
		{
			 boss = true;
		}

		if (boss == true)
		{
			Debug.Log("This is True, Like a boss!");
		}

		else
		{
			Debug.Log ("not like a boss");
		}

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

Your code should be in update, not in start.
