My problem is the following: is it possible using SAMP to set the camera's roll? For example, is it possible to adjust the camera so that when you turn your car upside down, the camera turns upside down with it?
Thank you for your answer. It is not what I am looking for. I am in search for a function which could make your camera TURN, for example roll upside down. If you are flying upside down, I could create a script so that the camera is turning with it as well, so flying and/or driving can be more realistic (vehicle quaternions can be converted into Euler angles, so that wouldn't be a problem).
I understand MTA can also set the camera's roll as part of their camera matrix, but I am looking for some method to implement camera roll like you seen on this picture in SAMP.
