[Scenario]

You want to be able to move the whole entire set of textdraws (in this case, a HUD) from one position to another? If so, then you're going to have to destroy the textdraws and re-create them at the new location. I don't believe there's a "MoveTextDraw()" function. However, I do believe someone has invented an include that does this. If you want it- search for it.
