gr8guitar Posted October 25, 2022 Report Share Posted October 25, 2022 Hello. I have searched forum.simflight.com and other websites for examples but found no examples that worked. I am trying to read a Lvar and insert that value into an FSUIPC offset using the function. -------- This works but not efficient ------------- while 1 do FDValue = ipc.readLvar("L:CpitCmdrSetValue") ipc.writeSW(0x66F0,FDValue) ipc.sleep(50) end ----------- offset into lvar = works but need lvar into offset ----------- function PanelShow(offset, val) val = ipc.readSB(0x66C0) ipc.writeLvar("L:PANELTYPE", val) end event.offset(0x66C0,"SB","PanelShow") ===================================== The two examples below do not work: Why not? ------------------------------------- function FDCmdrShow(offset, val) val = ipc.readLvar("L:CpitCmdrSetValue") ipc.writeSW(0x66F0, val) end event.offset(0x66F0,"SW","FDCmdrShow") --------------------------------------- function fdcmdrvalue (LvarName,LvarValue) ipc.writeSW(0x66F0,LvarValue) end event.Lvar("CpitCmdrSetValue",100,"fdcmdrvalue") ========================================== Link to comment Share on other sites More sharing options...

If that isn't working, I expect this is because the lvar doesn't exist when you are calling the event.Lvar function - you can test for this using the ipc.getLvarId function, e.g. function fdcmdrvalue (LvarName, LvarValue, userParam) ipc.writeSW(0x66F0, LvarValue) end id = ipc.getLvarId("CpitCmdrSetValue") if id == nil then ipc.log("Lvar CpitCmdrSetValue doesn't exist!") else event.Lvar("CpitCmdrSetValue", 100, "fdcmdrvalue") end Also, please try using the lua debugging facilities (using Debug/Trace Lua plugins from the Logging tab with Send to console window checked) to see what is occurring in your lua scripts. You can also take a look at your FSUIPC log file if the console window output scrolls too fast for you to read. John Link to comment Share on other sites More sharing options...
gr8guitar Posted October 26, 2022 Author Report Share Posted October 26, 2022 Hello. I will give it a shot. The lvar exists as I mentioned, the "while 1 do..." works, just not efficient. I am logging but within FSUIPC's logging tab so I can see the value 66F0 change. It just didn't work when I attempted to use the function and event.Lvar. I will continue. Thank you for your time and information. Link to comment Share on other sites More sharing options...

But that is in a loop. The lvar can be created after the loop starts, but the lvar will be read once it is available. With the event.lvar call, the lvar should be available when you call this (I think!), which is why I suggested adding that check. 3 minutes ago, gr8guitar said: I am logging but within FSUIPC's logging tab so I can see the value 66F0 change. That is the offset monitoring. Try the debug /trace lua plugins to see what is happening. With the information you provided, I do not even know if that lua script is running (or what FS or version of FSUIPC you are using) If you want further assistance, please attach your lua file (not paste its contents), together with your FSUIPC ini and log files, the latter generated with logging for lua plugins enabled.

gr8guitar Posted October 26, 2022 Author Report Share Posted October 26, 2022 Hello John. Will do. Again, thank you. Okay update John. I had to update! I was reading a post that stated event.Lvar wasn't available to v4.841. I was using v4484. Updated to v4.97a. I rarely update, unless something doesn't work. My primary FS is still FS2004! I have too much invested in FS2004 and its addons. I haven't tried event.Lvar in v3.999z. Thank you John (and Pete) for offering 3.999z keys for free. I did purchase v3 and 4 FSUIPC a long time ago but not WideFS (yet). Link to comment Share on other sites More sharing options...
