Problem with ipc.display


Recommended Posts

Hi Claude,

Is this a lua script? If so, 'print' is not a statement and will cause the script to fail. And, without tis line, the script would end very quickly anyway!

Also, how are you starting the lua? In FSUIPC, to automatically start a lua script it must be added to the '[Auto]' section, otherwise it should be activated from a button or key press.

If you are trying lua for the first time, you can also try activating 'Log Lua plugins separately' (and maybe 'Debug/Trace Lua plugins') from the FSUIPC logging tab, which will create a <yourLuaScript>.log file.

Also, please check-out the documentation and example scripts provided.

Cheers,

John

Bonjour John,

Print is here only to have a trace in the fsuipc log file.
The script is called with a joystick button.

I have of course use the console to trace  the lua script, and have activate the lua log but nothing special in it.

The  script is this one

Quote

print("display")
ipc.display("HI")
ref = sound.play("GearUpCall")

 

The print "display"  works and I can see it in the fsuipc log
The display("HI") doesn't work
The sound is played without a problem.

Cheers

Claude

Quite possibly your display window may be off screen if undocked and set there once before.
In FSX this display location is saved in a saved flight file.
Maybe try setting a new location and also give it a display duration in case it is clearing too quick.
Also try in windowed mode if you are full screen.

ipc.setowndisplay("My Lua Display Test", 48, 2, 4, 0) -- this will relocate the window top dead center in the fs main window
ipc.display("HI", 5-- 5 second display duration
ref = sound.play("GearUpCall")

On P3D4 with FSUIPC5, the displays use SimConnect windows, and can't be set with a user title. Their position can be remembered. FSUIPC stores that (but optionally and defaulted off because of Windowed mode / Full Screen changeover problems with it),

I think the problem is simply that the plug-in only exists for a fraction of a second. Display windows are closed when the requesting plug-in closes. if you want to see it, try adding an ipc.sleep(5000) at the end, so it hangs around for 5 seconds. (The sound request won't delay its termination -- that only initiates the sound).

Hi Pete,

Of course you are right, it is obvious now that the script terminate before it has the time to display the window. What an idiot I am.
I have 50 years of software development  behind me, and it looks like a beginner's mistake. May be I am getting younger...😃 or NOT !

Thanks Pete

Cheers

Claude
