Select multiple objects

Hello,

I wrote this script that draws a box on the screen with the mouse, like RTS games.
How can I select every object that is inside this box?

In other words, how can I access these objects and change their variables?

#pragma strict

var MenuSkin : GUISkin;

private var clickPosX : float;
private var clickPosY : float;
private var CurPosX : float;
private var CurPosY : float;
private var drawing : boolean;

function Update() {
	if(Input.GetMouseButtonDown(0))
	{
		drawing = true;
		clickPosX = Input.mousePosition.x;
		clickPosY = Input.mousePosition.y;
	}
	if(Input.GetMouseButton(0))
	{
		CurPosX = Input.mousePosition.x;
		CurPosY = Input.mousePosition.y;
	}
	if(Input.GetMouseButtonUp(0))
	{
		drawing = false;
	}
}

function OnGUI() {
	GUI.skin = MenuSkin;
	if(drawing && clickPosX != CurPosX)
	{
		GUI.Box (Rect (clickPosX, Screen.height - clickPosY, CurPosX - clickPosX, Screen.height - CurPosY - (Screen.height - clickPosY)), "");
	}
}

Assuming the objects have colliders on them, a CapsuleCastAll or SphereCastAll that covers the selected area should do the trick! Then loop through the resulting array to find what was hit.
