Any tips on how to make a full 360 camera backflip system?

[storm token]

Im not asking for a full on script, but rather a tip or what i should know on how i can start making this,

I dont really know much about Camera Manipulation so i dont know how to make the player be able to manually flip their camera 360 or -360 while still being able to be done in all camera person(s) (3rd person, 1st person,)

so far this is only what ive done, i dont know what im doing wrong

ive never rly messed around with cameras either

but i had this idea for this

• have a part welded to the character, and this part will be at the camera's default location

but this way, the camera will move along with the character

leme try it myself
