GUITex Position To GUI Rect

Description

A helper function to convert a GUITexture position to the equivalent Rect.

Usage

PosToRect (position : Vector2, bounds : Rect, pixelInset : Rect) : Rect;

position - the guiTexture's transform.position x and y components as a Vector2.

bounds - the equivalent of a custom pixelRect for rendering the guiTexture into. Uses GUI coordinates.

pixelInset - the pixelInset (Rect) of the guiTexture.

function OnGUI () {
	var rect = PosToRect(Vector2(pos.x,pos.y),Rect(10,10,200,200),Rect(-10,-10,20,20));
	// set rect to the GUI Rect of a guiTexture at position pos with a pixelInset of (-10,-10,20,20)
	// drawn as if by a camera with a pixelRect equivalent to (10,10,200,200)
	GUI.DrawTexture(rect,texture); // draw the texture at the new rect
}

function PosToRect (pos : Vector2, bounds : Rect, inset : Rect) {
	i = inset;
	rect = new Rect(0,0,0,0);
	rect.x = bounds.x + (bounds.width * pos.x) + i.x;
	rect.y = bounds.y + (bounds.height * pos.y) + i.y;
	rect.width = i.width;
	rect.height = i.height;
	return rect;
};
