error on sound.play

[Steve Johnson]

Hi Pete,

I have been trying to play a 2 second wav from a Lua script (it's for the stall test switch) and I am getting an error with the ipc.debug program on the line where I have used the sound.play. I have searched through the pdf manuals with the keyword sound but I have not been able to find anything.

This is the code that is causing the problem,

sound.play("c:\\sounds\\stall.wav")

ipc.sleep(3000)

The wav file is at this location: C:\sounds\stall.wav

ipc.debug writes this to the log file:

2940448 *** LUA Error: ...es\Microsoft Flight Simulator X\Modules\MW_Panel.lua:29: attempt to index global 'sound' (a nil value)

2940448 LUA: ended "C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Modules\MW_Panel.lua"

2940448 System time = 23/03/2011 20:07:31, Simulator time = 20:07:47 (20:07Z)

********* LUA execution terminated: Log Closed *********

As always, any help would be very much appreciated

That simply means that the "sound" library isn't defined (i.e. it is "nil"). I think you must be using a version of FSUIPC before the "sound" library was added. If you look at the headings of the Lua library documents you are referring to, don't you see an FSUIPC version number?

Try the interim FSUIPC update available in the Download Links subforum.

Hi Pete,

I have applied the interim update and it is now working fine,

Thanks for your help.
