So, I was recently working on my first-person framework prototype, and I was using the default Roblox camera. One Issue I noticed while making the FP was that when we are in FP with Roblox default camera scripts, the camera is in the center of the head, and it pivots around the head’s center, which led to the top part of the torso being shown. As in real life and other FPS games like CS2 that show your own bottom body besides your head, this is not the same case. IRL, when we move our head, it pivots on our neck, and our eyes are at the front of the head and not just in the center.
The whole contraption of eyes, neck, and center of head kinda looked like a right-angled triangle to me, so with some trigonometry, I present you, the most realistic head camera movement system:-
