    Hi All,

    I am seeking to tie into the Live For Speed V3 Plugin, an algorithm I have developed and implemented in Visual Basic. The algorithm takes the body roll, pitch and yaw angles and from these derives the Euler Angles. I would like the SimTools Game Engine to output the Euler Angles and not the car body roll, pitch and yaw angles.

    My Visual Basic code requirements are:
    1. One off object initialisation at the start of a race / practice session
    2. Maintain knowledge of previous car orientation variables (roll/pitch/yaw)
    3. Update and return Euler Angles

    Having studied the Live For Speed Plugin Code I believe that the following modifications should work.

    1) Requirement: One off object initialisation at the start of a race

    Sub ResetDOFVars()
    - place initialisation of the Euler object here (will need to add in class import to Plugin.vb)
    - I am assuming this sub is called at start of race and not at start of gaming session ...

    2) Requirement: Maintain knowledge of previous orientation variables (roll/pitch/yaw)

    a) Class Plugin in Plugin.vb
    - Add declaration of Prev_Roll_Output, Prev_Pitch_Output, Prev_Yaw_Output next to declaration of Roll_Output, Pitch_Output, Yaw_Output

    b) Sub ResetDOFVars() in Plugin.vb
    - place initialisation of the Prev_Roll_Output, Prev_Pitch_Output, Prev_Yaw_Output
    - I am assuming this sub is called at start of race and not at start of gaming session ...

    c) Sub Process_PacketRecieved in Plugin.vb
    - Assign Prev_Roll_Output, Prev_Pitch_Output, Prev_Yaw_Output values before updating the Roll_Output, Pitch_Output, Yaw_Output

    3) Requirement: Update and return Euler Angles

    Sub Process_PacketRecieved in Plugin.vb
    - Add in method to call Euler Angles class
    - Updating Euler Angles using increments in body angles, i.e.
    o dRoll = Roll_Output – Prev_Roll_Output
    o dPitch = Pitch_Output – Prev_Pitch_Output
    o dYaw = Yaw_Output – Prev_Yaw_Output​

    Function Get_RollOutput()
    - Alter function to return the Euler Roll Angle

    Function Get_PitchOutput()
    - Alter function to return the Euler Pitch Angle

    Function Get_YawOutput()
    - Alter function to return the Euler Yaw Angle

    Could you give any guidance on whether the above will work? Err and sorry the post is so long!

    Many thanks,
