I'm making a Rollercoaster-Tycoon clone in Unity, and have run into the issue of how to position tracks. I want the track to have an offset from the last placed track based on the direction of the camera. I tried using a Vector3 to offset the track, but that vector would only work for that specific direction. I need it to offset the track based on the direction the player is building in. (The camera's direction) What is a quick and simple fix for this issue?

You can try to use the Quaternion.LookRotation method to determine the rotation of the camera, and apply that to the new track piece.

Vector3 offset = camera.transform.forward * offsetDistance;
Vector3 newTrackPosition = lastTrackPosition   offset;
Quaternion rotation = Quaternion.LookRotation(camera.transform.forward);
newTrack.transform.position = newTrackPosition;
newTrack.transform.rotation = rotation;
