cam.Start3D2D help

[Commander11]

Is there any reason why this code is spawning my effect in a offset vector? I'll try subtracting some vectors later but hopefully someone can spot the reason for this madness?

[lua]
function ENT:Draw()
-- self.BaseClass.Draw(self) -- We want to override rendering, so don't call baseclass.
-- Use this when you need to add to the rendering.
self:DrawModel() -- Draw the model.

local ang = Angle( 0, 0, 0 );
local pos = self:GetPos();
local ExampleTexture = surface.GetTextureID( "sprites/sent_ball" );
local BoxSize = 128;

cam.Start3D2D( pos, ang, 0.25 );
surface.SetDrawColor( 255, 255, 255, 255 );
surface.SetTexture( ExampleTexture );
surface.DrawTexturedRect( 0, 0, BoxSize, BoxSize );
cam.End3D2D();
end
[/lua]

The 'offset' is probably the result of (0,0) being the top left corner of the box, to center it change line 14 to
[lua]
surface.DrawTexturedRect(-BoxSize/2,-BoxSize/2,BoxSize/2,BoxSize/2)
[/lua]

[lua]
local offset = Vector( 16, -16, 0 );
local pos = self:GetPos() + offset;
[/lua]

This seems to work fine.

But if you have another suggestion, I'd be more than happy to look into it.
