Wind Control Offsets 0x2DE0 / 0x2DE8 in P3D 64bit (v4/v5)

[RoB2]

Hi,

I am currently renewing my weather engine FSXWX and want to make it compatible for Prepar3D 64bit (v4/v5).

It is written in C#. So I already upgraded the FSUIPC Client DLL to the latest version and verified that the FSUIPC connection and writing offsets is generally working.

However, I am facing the problem that the wind speed/direction offsets 0x2DE8/0x2DE0 are not working any longer, which I have used for direct wind control (cf. the old post from 2012)

 

I tried various combinations of Prepar3D v4 and v5 with different version of FSUIPC v5 and v6. No luck. These offsets seems not to be writable any more.

Might be Prepar3D 64bit the reason for that? And if yes, is it possible to say if they are not working any more due to changes in P3D or if it would be possible to revive them with FSUIPC?
Unfortunately, I really don't know how to debug this problem...

Thanks a lot for your support!

Direct Wind Control is a hack in the 32-bit code of FSX and P3D, and is not applicable to the 64-bit P3D4 and P3D5 versions.  There are no hacks implemented in FSUIPC5 and FSUIPC6 which abide strictly to the SimConnect interface.

There are no plans to implement any hacks in the future. Sorry.

I see the offset documentation for write access on offsets 2DE0 and 2DE8 still says Ok-Hack - this is incorrect and should say No-SimC+ - I will update to make it clear that it is no longer possible to write to this offset to update.

Thanks for the confirmation!

It's a real pity that these offsets are not working any more and there are no plans to revive them.
Of course, I fully accept this decision. In case it would be achievable with reasonable effort, however, I would really appreciate to re-consider.

Most probably, FSXWX has become the largest free-to-use weather engine with complex weather depiction in the flight sim community. Thus, I guess many users would be happy to see it continue to work in v4/v5.
