Hello again pandako. I have a new request, make a separate video on how to make controls for a 3d game with turns. In the video about how to translate from 2d to 3d, the control does not work there. Thank you in advance!
The extension in the video is an older version, but the camera behavior hasn't changed much since then, so the current version doesn't change how you use it.
I recommend that you check the video carefully once again.
