I'm trying to lock camera CFrame to head, but player can rotate camera. And i see bugs when player go sideways/backward

Can you explain a bit more clearly on what these “bugs” are?

Also instead of printing if they walked left or right you could save the cframe of the heads position and when they walk right it sets the head cframe to the stored cframe that we had gotten earlier.

^^ This is suggested because of your lack of disclosure on the “bugs”

#3

Since the CFrame camera is attached to the head, it also shakes, like the head, but when the player turns the camera to the side (for example, to the left and let’s say he holds A and so he goes sideways), the camera starts to shake strongly, and this also happens with a camera if the player walks backwards

#4

Have you tried ignoring the roation on the cframe? That seems to be what is going on.

What I mean is to pretty much set the orientation to 0,0,0 although I recommend to figure out what is the root cause you could sit on the properties tab and monitor the CFrames as you move around and observe the behaviour.

yay! it works! but my camera after i stopping walking is not smoothly moves. How to fix it?
