Help needed on creating a camera rigidly attached on vehicle

Jiaming Sun

Hi there, I'm working on a mod with a need of attaching a stereo camera in front of the vehicle(the direction and position of the camera is fixed with the vehicle, like one of the 'v' camera view in the game), but I can only fix its position with camera.AttachTo(), the direction is fixed to a direction in the world coordinate, not the vehicle coordinate. This is the code I'm using(ScriptHookVdotNet):

    public StereoCamera(Entity e)
    {
        leftCam = World.CreateCamera(GameplayCamera.Position, GameplayCamera.Direction, GameplayCamera.FieldOfView);
        rightCam = World.CreateCamera(GameplayCamera.Position, GameplayCamera.Direction, GameplayCamera.FieldOfView);
        // leftCam.PointAt(e.Rotation);   // I tried this but not working as expected.
        leftCam.AttachTo(e, new Vector3(0, 1, 1));
        rightCam.AttachTo(e, new Vector3(0, 0, 1));
    }

How do I create a camera with its direction fixed with the vehicle? Do I need to update the camera direction with a custom Update() function? Is there any example for this update function..
Any help is greatly appreciated!

You can use the camera.PointAt function. IIRC there is an overload that allows you to point at a specific bone on the vehicle. You could also just use the overload that allows you to provide an offset.

Thanks for your reply!
The problem is resolved by adding a Update() function into onTick().

    private void UpdateCams()
    {
        // Set the camera rotations to match the vehicle
        LeftCam.Rotation = PlayerVehicle.Rotation;
        RightCam.Rotation = PlayerVehicle.Rotation;
    }
