Thanks for the clarification

Thanks Mr.Pete Happy Holidays! I dont want to use trigger it off from a button. More so it will be called from ipcReady ( basically to do after take off procedures ) ..button was just for testing purpose. There was some change in the code as i was testing and hence i posted back the new code - never mind that. As I understand, the listner ( events ) keep adding to the windows queue for processing but at a certain point ( when user conditions were met) the function was cancelled (function pointer became null ) so when the pending events ( windows queue) fired they were trying to execute a function pointer pointing to null causing the crash.

test.lua ----------- function geardown(offs, val) msg = "" if val == 0 then msg = " up " else msg = " down " end ipc.display ( "gear"..msg) ipc.sleep(500) if msg == " up " then event.cancel("geardown") -- ipc.exit() end end -- to kick it all off: event.offset(0x0BE8, "UW", "geardown")

The lua plug in will finally go into ipcReady once it takes shape, but for now in the learning phase,,,just trying a few things Here are the details.. 48017 Starting everything now ... 48017 LUA.0: beginning "D:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Modules\ipcReady.lua" 48017 LUA.0: ...es\Microsoft Flight Simulator X\Modules\ipcReady.lua:1 48017 LUA.0: Global: ipcPARAM = 0 48033 LUA.0: ended "D:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Modules\ipcReady.lua" 48048 FollowMe service initialised and ready ... 49343 Advanced Weather Interface Enabled 52697 KEYDOWN: VK=76, Waiting=0, Repeat=N, Shifts=0 52697 ..

just to add to the above... function geardown(offs, val) msg = "" if val == 0 then msg = " up " else msg = " down " end ipc.display ( "gear"..msg) -- cancel the event so that next time button press should not do action. event.cancel("geardown") [ this causes the crash..if i comment out this line then no problem] *************** if i add the following line of code the crash goes away ipc.exit() end

Hi I just wrote a small piece of code test.lua fired by a button press and when the aircraft gear is activated I wanted to display gear up or gear down as a message. I dont know if I'm implementing event,cancel properly.Below is the code snippet that is causing the crash. Thank you test.lua function geardown(offs, val) msg = "" if val == 0 then msg = " up " else msg = " down " end ipc.display ( "gear"..msg) -- cancel the event so that next time button press should not do action. event.cancel("geardown") [ this causes the crash..if i comment out this line then no problem] end -- to kick it all off: event.offset(0x0BE8, "UW", "geardown") following is the error line from the console window 38438 LUA.0: Waiting for an event in "D:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Modules\test.lua" 38438 LUA.0: Offset Change event: calling "geardown" in "D:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Modules\test.lua" 38438 LUA.0: ...

I just figured i could achieve it using offset 0D70. Thanks

Hi I want to be able to toggle flags via lua script. I tried to achieve the functionality through ipc. Setflag & ipc. Clearflag but it didn't work. If i use a joystick button and use luatoggle then it works. However i need to be able to do it via script since i may need to start 5 or 6 threads. What is it that im missing. Thanks

Is LINDA an alternative to FSUIPC??

so how do i convert the value obtained ( from offset 0x2EA0 ) to degrees P.S: Not good in maths :)

Hi Mr Pete Dowson Sir I'm a newbie to FSX and FSUIPC as well. So please bear with me if I have asked you a silly question and not googled hard for a similar question/solution already asked and answered. I have a requirement in which I wanted to read/write Pitch & Elevator Trim executed via lua scripting triggered by a button in a Joystick. I'm new to FSUIPC and hence started browsing example code from your collection of lua scripts ... and slightly modified "Display Vals". The offset document and code example( display vals, liar) is neat and clear when it comes to reading/writing Pitch/Altitude, etc but I could not find any example for reading/writing elevator trim...especially how to convert the value read from offset 0x2EA0. I have a gauge( XML in Panel) displaying ( digital readout ) of Elevator Trim( <String>T:%((A:Elevator Trim Position,degrees))%!2.2f!</String>) and I was trying to verify the data read from offset with the digital read out. My question a) what is the formula to convert value read from offset 0X2EA0 ( so that it would match my reading from gauge) b) if i write ( as per the example code in "Liar" example LUA plug-in for FSUIPC4/ESPIPC only, by Pete Dowson, January 2009) will it reflect really the changes in FS). The reason I'm asking is based on your comment "alter them all to values we want to fool other FSUIPC clients to believe" Need your guidance Thanks very much Regards Janakiraman Swaminathan display vals.txt
