How to make a camera script alike that of the default?

So...

I found a free model that's an upside down land...

And I wanna make it so that the camera flips around so that it's basically just a normal view from upside down...

But I need the Camera to be scriptable.

and i'm too nubby to implement a full-blown camera script :(

Not only that, but I can't get mehr roll roight

curcam:SetRoll(0.8) -- IT'S NOT ROIGHT
-- CRI CRI

so

halp

pleb

(btw no i'm not asking ya'll to fix a free model)

(Also btw, apologies if I'm not meeting the effort criteria)
