simscript's Issues
FalconSharedMemoryAreaString
I've also tried to access this part of the shared memory. I ran into an issue where I'm totally lost: std::string strData in line 785 inside the FlightData.h. A few lines below seems to be a guide on how to parse and reconstruct the actual data from it, but it's way over my head.
Do you have an idea how to work this out and perhaps include it in modules/falcon.py?
Cannot initialize DLL for FSX Simconnect
Hello, I am new to GitHub, so no Idea if I am right here.
I just got a question to your simscript. I downloaded the simconnect program from: https://github.com/nmeier/simscript/releases
When I create my own script in the scripts-Folder and I just do that:
import log
log.info("Testing...")
Then I start simscript.exe and start my file with the menu of the traybar icon. Everything works fine then. It outputs "Testing..." all the time.
But when I make this:
import log, fsx
log.info("Testing...")
It just says
"Cannot initialize DLL for FSX SimConnect".
What do I wrong? Do I have to do something else or update anything?
I really hope this is the right place to write and you can answer me. Because this Library is SOOO awesome. Thank you so much. It ist indeed the easiest way to program FSX Things. I got a really nice Idea and hope you can answer me :)
With best regards, Noah
FalconSharedMemoryArea2
I am trying to get values from FalconSharedMemoryArea2. I have tried to modify falcon.py to include some of the data from it, but without much success.
I wanted to access the FlyState. Running the script below isn't returning integers in the range of 0 to 5 as expected, but somewhat random longer integers (01241535 for example). I'm not very knowledgeable about this and I'm pretty sure I'm doing something wrong. How would I access the FlyState?
Edit: I have made some progress.
I have added the FLIGHTDATA2 structure. I am however unsure if I assigned all the ctypes correctly. I am also getting a weird byte for pilotsStatus. I assume I am using it wrongly? How would I get the correct pilotsStatus?
Here's my modification of falcon.py:

Thanks for this neat utility. I would have never figured out myself how to access Falcon BMS' shared memory via Python without it.
