Lua Help please

[OwenM]

Hi all

 

I have a RAAF MRTT kC-30 Tanker sim that does all the normal tanker things like extend Hoses and extend boom.

 

I have been playing round with capturing the LVar data (when it changes) for the hose extension and boom extension and writing the data to Offset 66C0 and 66C2 where I an read it with my Delphi app that runs my annunciator.

These scripts are all in the Auto section of FSUIPC.ini

I made a Lua script that I thought should work but it doesnt . There is no error message in FSUIPC log 

OLD_MRTTPOD = 0
OLD_MRTTBOOM = 0

while 1 do
MRTTPOD = ipc.readLvar("L:MRTTPOd")
MRTTBoom = ipc.readLvar("L:MRTTBoom")

if MRTTPOD ~= OLD_MRTTPOD then
ipc.writeSW(0X66C0, MRTTPod)
OLD_MRTTPOD = MRTTPOD
end

if MRTTBOOM ~= OLD_MRTTBOOM then
ipc.writeSW(0X66C2, MRTTBoom)
OLD_MRTTBOOM = MRTTBOOM
end 

-- DELAY
ipc.sleep(100)
end

however if I break it down to two individual scripts as follows they both work perfectly 

OLD_MRTTBOOM = 0
while 1 do
MRTTBoom = ipc.readLvar("L:MRTTBoom")
if MRTTBoom ~= OLD_MRTTBoom then
ipc.writeSW(0X66C2, MRTTBoom)
OLD_MRTTBOOM = MRTTBOOM
end

-- DELAY
ipc.sleep(100)
end

 

and the Pod script 

 

OLD_MRTTPOD = 0
while 1 do
MRTTPOD = ipc.readLvar("L:MRTTPOd")

if MRTTPOD ~= OLD_MRTTPOD then
ipc.writeSW(0X66C0, MRTTPOD)
OLD_MRTTPOD = MRTTPOD
end

-- DELAY
ipc.sleep(100)
end

 

I thought it would be tidier to have them in one script but after hours of tinkering I have had to resort to  using the two scripts.

 

Just wondering if anyone can point out my error in the first script

 

Thanks heaps

All that code looks like you are waiting for an L:Var change, if it does, write to 0x66C0 & C2 as signed words.
The following code could (not tested) replace all that by using the on "event" listeners in the lua library.
The function will not do anything until a L:Var change.

When logging luas, use the left side option of the logging tab "Debug/Trace Lua". (something like that)
Looking at your "all in one" code the only thing I found, and is probably the reason... 
"MRTTBoom" is not the same variable name as "MRTTBOOM" , CaPiTaLiZaTiOn counts.. 😉

 

function write2offset(varname, value)
	if varname == "MRTTPOd" then
		ipc.writeSW(0X66C0, value)
	else
		ipc.writeSW(0X66C2, value)
	end
end 

event.Lvar("MRTTPOd", 250, "write2offset")
event.Lvar("MRTTBoom", 250, "write2offset")

Thanks Roman

Your Code worked just fine and is a lot better way for sure

Thanks again
