Welcome to the ZDoom Forums!

Is it possible to make the status bar vanish at certain points in the game without the user doing anything?

(I'm considering replacing my scripted hud with an sbarinfo one but I want it to vanish during the intro, endings & credits cinematics)

Yes. Give the Player a specific Inventory item when you want it to vanish, then wrap the whole status bar in an "InInventory Not" block that checks for that item. (This would only work well if it's a "fullscreen" style, I.E. Height 0, otherwise you'd end up with HOM where the bar should be - Of course you could draw a blank box there for story text!)

Edit: Agh spelling. -.-

Not if you use completeborder.
