GraphicsWidth ( )

Parameters

None.

Description

Returns the width of the current graphics display, in pixels.

This is the width passed to Graphics (or Graphics3D). Use it instead of hard-coding the number, and code like x=GraphicsWidth()/2 keeps HUDs centred and clamps player positions correctly at any resolution you later switch to.
