Need help with movement for first person vr game

I have been attempting to make a vr game like OPPOSER VR
I have attempted to make something like it but it was very buggy and didn’t work really well. I am stumped because there are not really any tutorials I can find or any topics posted here that can help me with my problem. I have been attempting to change the camera’s cframe but I’m unsure if theres a different way.

I would really appreciate the help as I am very clueless and want to continue making my game.

There are plenty of tutorials on Youtube on getting started but there’s not a lot to work with farther down the line.
