DOCS ACC Shared Memory Documentation

Hi, According to the latest Share Memory Doc (v1.8.12) physics page contains Mz (self aligning torque) parameter, but these values are all empties (zero). I use the latest ACCSM_Example to test. I have the latest version of AC from Steam on Windows 10 64bit. What wrong?

 

Will there be an update to the shared memory manual that contains the Porsche 992 GT3-R 2023 from the "GT World Challenge 2023" DLC?

 

Same, I tried to get the values for mfdFueltoAdd, mfdTyrePress from GraphicsUpdated method, but they all return 0.. will there be an update to ACCSM Example? Am i missing anything?
If someone has a working ACCSharedMemoryPlugin.dll please do share

 

Can anyone confirm what the coordinate system is for the local physics vector values, such as LocalVelocity, AccG, LocalAngularVelocity etc.

 

I want to start working on my own app, but before I get too far in to it is it possible to get the setup data from shared memory or UDP?

 

Hi, there is no setup data coming via Broadcast data nor SharedMemory.

There is no public way to access the current car setup real-time. If you really want to get access to the setup data, you have to ask your users to always save the setup they are using for the session, then load the setup data via the app, where you have to parse the JSON setup file and set the parameters in your tool. So not very easy or something, you can easily automate. One option I have been thinking, is that the driver would always save the setup with the same name, i.e. the driver can have several setups, but before starting the session, save it e.g. as 'ActiveSetup' and then my Tool would load that file. Problem is that the driver must always do that and if they don't, then the data is not valid/current.

Cheers.

 

Update please

 

Hi Guys,
I have a request.

Where can I find in shared memory the Cup category of a driver?
I mean: I have car classes, but there are also driver classes (Gold/Pro, Silver/Pro-Am).

How can I found this info of my driver and all opponents?
I read in documentation this:

wchar_t carModel[33] Player car model see Appendix 2
wchar_t track[33] Track name
wchar_t playerName[33] Player name
wchar_t playerSurname[33] Player surname
wchar_t playerNick[33] Player nickname

but no mention about Driver Class.

Thank u so much for your support.

 

You'd have to use the Broadcast/UDP interface. Download the dedicated server and look in
\SteamLibrary\steamapps\common\Assetto Corsa Competizione Dedicated Server\sdk\broadcasting\Sources\

The InboundMessageTypes.ENTRY_LIST_CAR message gives all the driver details

 

Hi Doug,
Sorry about that.. I have not so much experience.

I did not know that there is a broadcasting server for that.

There are some code examples on how to connect to this interface and how to retrieve data?

Thank u so much. I really appreciate your support

Sorry another point:
Do I need to start any ACC server broadcasting for obtain this information?
I'm asking because I know plugins for SimHub that are returning those info without any server running on local.

 

While Kunos included the sample in the server stuff, it actually runs against the client - IIRC they give a running sample that you can amend. If you are going to use the UDP interface, head over to the Broadcast/Programmers thread - someone gave a fix for session cleanup which addressed a bug in the sample. I'll see if I can find a reference to it

 

I have implemented the client, registered, received the REGISTRATION_RESULT event, and when I request the RequestEntryList as per the SDK code:

Code:

Code:

using (var ms = new MemoryStream())
using (var br = new BinaryWriter(ms, Encoding.UTF8))
{
   br.Write((byte)10); // First byte is always the command type
   br.Write((int)connectID);

   return ms.ToArray();
}

It returns a new event 10 and then a 9...

But from what I understand, 10 and 9 are outbound and not inbound.

Code:

UNREGISTER_COMMAND_APPLICATION = 9,
REQUEST_ENTRY_LIST = 10,
}

I'm sure I'm doing something wrong, but I don't understand where. However, registration seems to be correct, returning the REGISTRATION_RESULT event (1).

If you want, I can post the code here to understand better.

Sorry, I'm not very experienced.

 

Obviously Code would help massively.
the REQUEST_ENTRY_LIST is a requesting event (as the name might suggest). So you need to Fire that Event and then wait for an Incoming Event. In this case EntryListMsgType and / or EntryListCarMsgType. Beware that in Team Races some driver details need to be requested again at a later point. The SDK that comes with the dedicated server stuff all handles that, so most of the code / logic u need u will already find there.

 

I figure out!!!
easier that I though.. I just copy paste the classes of the sdk, and magic was done.. before I was creating my udp connection by myself.. so stupid!
Thank u for support

 

Exactly.. I was refactoring them...instead to copy paste the classes and use them like they are hahaa

Thank u so much!

 

BTW, if you are copying the sample, bear in mind it is a little leaky. @expor found a solution (see https://www.assettocorsa.net/forum/...-programmers-thread.53826/page-6#post-1137208 and https://www.assettocorsa.net/forum/...-programmers-thread.53826/page-7#post-1137264). Also, the sample just creates new connections for each session and doesn't really clean them up. If you don't handle both these, you will eventually crash ACC (ask me how I know )

 

Yep thank u for the tip.
I will exactly create only 1 connection, I saw about that.

But thanks for the section of re-connection.. I was already looking into that.

 

Hy guys
Another question.
About the value strategyTyreSet of SPageFileGraphic, what is expected to have?
because as I saw in the sim, it returns me the current tyres I'm on... mmmm
There is a specific properties to check the "next tyres type" will be changed in next pit?
I mean: i would like to know if next pit I will mount dry/wet tires, and if dry, which set.

Thank u

 

SPageFileGraphic
mfdTyreSet

 

Hi Arotho, yes and no.. I mean.
The value mfdTyreSet goes from 0 to 49 and are the DRY tyres set.
But if I set WET tyres, this value is not changing.
How can I know if I selected WET or DRY tyres for next pit?
Thank u buddy
