    Thanks Pascal, I will check it.

    I wonder if something equivalent could be done for the Mac, only IPACS has the answer, I guess.

    Hi Pascal, thanks for your interest in the project.

    I did some new updates. I deleted the Python app with GUI, since I still need to find the offsets for all variables to be displayed and continue fixing this app.

    Please download the actual DLL from the Github, it is more complete since I added some missing variables.

    The file AeroflyBridge.dll must be saved in your Aerofly FS 4\external_dll folder, in my case here:

    C:\Users\Admin\Documents\Aerofly FS 4\external_dll\AeroflyBridge.dll

    This is where the community files must be added to the sim, we never modify the simulator folder.

    I have tested it in two computers and it works well on both of them.

    For testing the DLL communication you can use the simple console scripts I added to the repository:

    aerofly_memory_scanner.py

    aerofly_realtime_monitor_all.py

    This is very early work in progress, I just added it to Github to share the work and the DLL source code.

    It is very shocking at the beginning with a lot of wow! moments, but as like with everything you get used to it. Maybe now the most impressive to me is the speed it can work. From the time I have been working in this, I doubt that Claude has been writing code for more than 1 hour. Most of the time is spend in discussions, analyzing, testing, fixing errors, going back and forward.

    Please anyone that wants to contribute to this new DLL development, please participate. This is for the benefit of all the AFS4 users.

    The new DLL is the tool we need to do the integrations with the real applications, is not an objective in itself. It is a bridge :)

    Hello! This is built 100% by AI. I started the project with Claude.ai web tool (similar to ChatGPT interface),. After the DLL code increases it size too much, it was difficult to work on it in the web tool, and I continued it in Cursor IDE, always working with Claude Sonnet 4. Before this project I had never compiled a C++ DLL or working with C++. Just as a reference, I haven’t worked more than 20-30 hours on this.

    Any suggestion to improve it is welcome, it is as easy as to ask the AI to implement it. I generally discuss all the decisions with it, and ask it for advice and suggestions.

    Thanks Frank for the suggestion! I will ask about it.

    And thanks Jan for the feedback, for the moment the main goal is to be able to read all the available variables and to be capable of doing control on all the ones we can write. In the Python app, when the category tabs are selected, I see a 10-15-Hz refresh. When all the variables are read in the last tab (last picture of the tab), it slow down to about 1Hz or less.

    When the first goal is achieved, I will try to improve the efficiency. One thing is pending is to implement this:


    ## Hash-Based Variable Processing Optimization

    ### Performance Issue

    Current variable processing uses sequential if/else chains:

    ```cpp
    void ProcessMessage(const tm_external_message& message) {
    const auto hash = message.GetStringHash().GetHash();
       
    if (hash == MessageAircraftLatitude.GetID()) {
    // process latitude
    } else if (hash == MessageAircraftLongitude.GetID()) {
    // process longitude
    } else if (hash == MessageAircraftAltitude.GetID()) {
    // process altitude
    }
    // ... 100+ more comparisons
    }
    ```

    **Problem**: O(n) complexity - worst case 100+ comparisons per variable

    ### Hash Table Solution

    Replace with O(1) hash table lookup:

    ```cpp
    class OptimizedVariableProcessor {
    private:
    std::unordered_map<uint64_t, std::function<void(const tm_external_message&, AeroflyBridgeData*)>> processors;
       
    public:
    void InitializeProcessors() {
    // Direct hash-to-function mapping
    processors[MessageAircraftLatitude.GetID()] = [](const tm_external_message& msg, AeroflyBridgeData* data) {
    data->latitude = msg.GetDouble();
    data->all_variables[(int)VariableIndex::AIRCRAFT_LATITUDE] = msg.GetDouble();
    };
           
    processors[MessageAircraftLongitude.GetID()] = [](const tm_external_message& msg, AeroflyBridgeData* data) {
    data->longitude = msg.GetDouble();
    data->all_variables[(int)VariableIndex::AIRCRAFT_LONGITUDE] = msg.GetDouble();
    };
           
    // Add all 285+ variables...
    }
       
    void ProcessMessage(const tm_external_message& message, AeroflyBridgeData* data) {
    const uint64_t hash = message.GetStringHash().GetHash();
           
    auto it = processors.find(hash); // O(1) lookup
    if (it != processors.end()) {
    it->second(message, data); // Direct function call
    }
    }
    };
    ```

    ### Performance Benefits

    - **Speed**: 10-50x faster processing (O(1) vs O(n))
    - **Scalability**: Performance doesn’t degrade with more variables
    - **Memory**: Minimal overhead (~8 bytes per variable)

    ### Implementation Benefits

    - **Cleaner Code**: Each variable has its own processor function
    - **Error Handling**: Individual try/catch per variable type
    - **Maintainability**: Easy to add new variables
    - **Debugging**: Built-in statistics and unknown variable detection

    ### Usage

    ```cpp
    // Replace your current ProcessMessage with:
    OptimizedVariableProcessor processor;

    void ProcessMessage(const tm_external_message& message) {
    processor.ProcessMessage(message, pData); // One line!
    }
    ```

    ### Critical Variable Prioritization

    ```cpp
    // Process flight-critical variables first
    std::unordered_set<uint64_t> critical_variables = {
    MessageAircraftLatitude.GetID(),
    MessageAircraftLongitude.GetID(),
    MessageAircraftAltitude.GetID(),
    MessageAircraftPitch.GetID(),
    MessageAircraftBank.GetID()
    // ...
    };
    ```

    **Recommendation**: This optimization is essential for production DLLs processing 100+ variables at high frequency. The performance gain is dramatic with minimal implementation effort.

    Hi, here it is the actual state of the DLL source code, so you can take a look:

    (Please see last post)

    And here it is the source code of the Python test program:

    (same)

    Work in progress, I want to check all the most important variables, but just wanted to share where we are.

    Here you can see some pics of the Python app communicating with the sim using the DLL:

    Here it is the first update about our work. Luckily, today is holiday in my country :)

    *Built with love for the Aerofly FS 4 community* ✈️

    I prefer to not have the real time weather, volumetric clouds, and other things that would consume resources, and keep the wonderful performance and fluidity of the sim, which makes it so special and different from other sims. Anyways, cows are nice :)

    Hi Jan /developers, can you check please the document if it is correct, something is missing, etc.

    Next step will be to build a new DLL that will provide us the shared memory access to the variables, so it would we great to know if we are starting from a good place.

    And next-next step, will be to build a Python sort of SDK to simplify the access to the shared memory varíables.

    If all this works, I will try to integrate Sayintentions.

    Hi! At some point, I believe after an AFS4 update, VR started degrading in my PC. Mine setup is not as powerful as gzt007,but I have the perception that VR was better in AFS4 some months ago. Anyway, I quit using VR since I realized that it increased the pc workload too much, and I prefer to do a conservative use of it, since I have invested a lot in hardware and software for it. I used also Virtual Desktop with the Quest 3.
