getting variables from other scripts C#

Questions & Answers

Hey i have been working on this script for a while and i have encountered a problem, and for the life of me i cant solve it. (using unity 5) when i run this script the TowerCanvas is always running instead of the MainCanvas and i have no idea why. i am using a raycaster to detect if the FoundHit variable is true or false. and it still works when the TowerCanvas is forcing itself on the screen. i have also made it so that when a press “Tab” MainCanvas pops up and TowerCanvas disappears, however when i click tab the Canvases switch for only one frame. i think there is something in the script forcing FoundHit to = true but at the same time i dont think so. there are only two scripts involved in the FoundHit var so there is no other script conflicting with it. if anyone knows how to help i will be so great full. here are the scripts:

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

public class HUD : MonoBehaviour {

bool FoundHit = false;

public Slider TowerHealthSlider;
public Slider BaseHealthSlider;

int CurrantTowerHealth;
int CurrantBaseHealth;

public Canvas MainCanvas;
public Canvas TowerCanvas;

public int StartTowerHealth = 100;
public int StartBaseHealth = 25;

bool TowerDead;
bool Basedead;

public Text Ammo;
public Text EnemiesLeft;
public Text GunName;

//may have to edit these later
string CurrantAmmo = "12 / 24";
string CurrantGunName = "Colt M1911";
string CurrantEnemiesLeft = "Enemies Remaining = 10";


public void Start () {

	CurrantBaseHealth = StartBaseHealth;
	CurrantTowerHealth = StartTowerHealth;
	Basedead = false;
	TowerDead = false;

	Ammo.text = CurrantAmmo;
	GunName.text = CurrantGunName;
	EnemiesLeft.text = CurrantEnemiesLeft;

	MainCanvas.enabled = true;
	TowerCanvas.enabled = false;
}

public void Update () {

	GameObject Camera = GameObject.FindGameObjectWithTag ("Camera");
	Clicking ClickingScript = Camera.GetComponent<Clicking>();
	bool FoundHit = ClickingScript.FoundHit;

	Ammo.text = CurrantAmmo;
	GunName.text = CurrantGunName;
	EnemiesLeft.text = CurrantEnemiesLeft;

	if (FoundHit = true){

		MainCanvas.enabled = false;
		TowerCanvas.enabled = true;
	}

	if (Input.GetKeyDown (KeyCode.Tab)) {

		MainCanvas.enabled = true;
		TowerCanvas.enabled = false;
		FoundHit = false;
	}
}

public void TowerTakeDamage (int TowerAmount) {

	CurrantTowerHealth -= TowerAmount;
	TowerHealthSlider.value = CurrantTowerHealth;
}

public void BaseTakeDamage (int BaseAmount) {

	CurrantBaseHealth -= BaseAmount;
	BaseHealthSlider.value = CurrantBaseHealth;
}

}

and the other:

using UnityEngine;
using System.Collections;

public class Clicking : MonoBehaviour {

public float RaycastDistance = 50;

public bool FoundHit = false;

RaycastHit Hit;

public GameObject Raycaster;

string TagCheck = "TowerBase";


void Update () {

	if (Input.GetKeyDown (KeyCode.E)) {

		FoundHit = Physics.Raycast (Raycaster.transform.position, transform.forward, out Hit, RaycastDistance);

		if (FoundHit && Hit.transform.tag != TagCheck){

			FoundHit = false;
			Debug.Log ("Not the TowerBase");
		}
		if (FoundHit && Hit.transform.tag == TagCheck) {

			Debug.Log ("You hit the TowerBase");
			//TowerCanvas.enabled = true;
		}
	}
}

}

Thank you!

Ok i fixed this by making the Clicking script have a new variable which was used across scripts
