Door opener

Hello i am having a game where diferent buttons are going to open different doors.

The code for the button use is:

var ButtonNr 	: int;

//Private Variables 
var isOn : boolean = false;
function Update () 
{
	if(isOn)
	{
		//OpenDoor(ButtonNr);
	}
}

public function UseButton()
{
	if(isOn)
	{
		isOn = false;
		renderer.material.color = Color.blue;
	}
	
	else if(!isOn)
	{
		isOn = true;
		renderer.material.color = Color.green;
	}
	print(isOn);
}

As you can see i have commented out OpenDoor(ButtonNr) as i dont know how to call it in a diferent script. the other script looks as this:

var DoorOpen	: boolean	=	false;
var DoorNr		: int;
function OpenDoor(nr : int)
{
	if( nr == DoorNr && !DoorOpen)
	{
		Destroy(gameObject);
	}
}

i need it to test all of the doors if there button have been switch on is there a way to individualy check all doors ?

thanks for your time and i hope you will help

There are several ways to do that, but I would do the following:

1- Create an empty object, call it “Doors” and reset its position and rotation;

2- Child all doors to this object;

3- Modify the button script like this:

var ButtonNr : int;
static var theDoors: GameObject; // reference to "Doors" object

function Start(){ 
    // first button executing Start assign theDoors:
    if (!theDoors) theDoors = GameObject.Find("Doors");
}

//Private Variables 
var isOn : boolean = false;
function Update () 
{
    if(isOn)
    {  // call the function OpenDoor(ButtonNr) in all children of "Doors"
       theDoors.BroadcastMessage("OpenDoor", ButtonNr, SendMessageOptions.DontRequireReceiver);
    }
}

public function UseButton()
{
    if(isOn)
    {
       isOn = false;
       renderer.material.color = Color.blue;
    }

    else if(!isOn)
    {
       isOn = true;
       renderer.material.color = Color.green;
    }
    print(isOn);
}
