Hi, so I am trying to make a GUI crosshair which I will later change(based on the weapon’s accuracy). Problem is, I don’t really understand how the GUI system works, since I have only done one thing with it, and I need help. I have an empty game object, with this script

function OnGUI()
{

	GUI.Box(Rect(0,0,15,15), "");

}

What else do I need to do to make it appear? Thanks!

#pragma strict
var chTexture : Texture2D;
var positionch : Rect;
static var ch = true;

function Update() // If we don't do this, we can't update the size.
{
    positionch = Rect((Screen.width - chTexture.width) / 2, (Screen.height - 
        chTexture.height) /2, chTexture.width, chTexture.height);
}
//We need to draw the texture on the gui 
function OnGUI()
{
    if(ch == true)
    {
        GUI.DrawTexture(positionch, chTexture);
    }
}

Attach it to a gameobject, and put a texture in the inspector.

var crosshairTexture : Texture2D;
var position : Rect;
static var OriginalOn = true;

function Start()
{
position = Rect((Screen.width - crosshairTexture.width) / 2, (Screen.height -
crosshairTexture.height) /2, crosshairTexture.width, crosshairTexture.height);
}

function OnGUI()
{
if(OriginalOn == true)
{
GUI.DrawTexture(position, crosshairTexture);
}
}

this script works wonderfully
