Player turning stopped working

Not sure of the best place to post this question, but…

I’m experimenting with sound design with FMOD and Unity, and I’ve broken something unrelated to the audio and would like to fix. The player character should turn to face the mouse cursor, but no longer does. I’m using the tutorial project “Survival Shooter” as a base. Using the completed version of the project, I’ve disabled the included sound assets and started to add my own, with a little scripting to hook into the FMOD plugin. I did make some minor changes to the PlayerMovement script, but I don’t think those could be the cause because I’ve tried pulling pulling a fresh copy of that script (i.e. without any of the changes I made) into the project and the turning still doesn’t work.

I’ve made very few changes to the project other than a) importing the FMOD package, b) adding a couple scripts to control audio assets, and c) very small modifications to the PlayerMovement script. Can anyone offer any suggestions as to where to look for the source of this issue, or any ways to help troubleshoot it? Thanks.

I sorted it out. There was a Floor layer missing that prevented the ray cast from hitting.
