Cheat Engine help with camera mod making

Hello, Ive been dabbling in cheat engine for a little bit now and one of the biggest things ive wanted to be able to do is camera mods such as making a third person game be first person etc. Ive read whatever information ive been able to scrounge up for stuff like that however i seem to find the amount of info on how to do things a bit scarce. Anyways, I know when looking for cameras im supposed to look for float values and start with unkown initial value then move the camera either left, right, up or down and search for an increased or decreased value accordingly, but i havent really had any luck so far in pinpointing camera values in any of the various games ive attempted to hack. that being said i dont even entirely know what to do assuming i DID find the value, im trying to do things where the camera would obviously stay in a first person esque view, even attaching the camera to my characters head is fine with me, from my small background in hacking and cheat codes i know the general concept entails probably finding the camera value and finding the character value then making the cameras position be the same as the character or depending on the game possibly slightly in front of the character, then adjusting it to be about head height, some people even make the character model invisible for something like that. Regardless i think after this paragraph ive expressed my own current understanding and my problem, if someone could help explain to me how to go about things like this id be much appreciative, and i thank you for taking the time to read this.
