LUA Friction question

[PhugoidEffect]

Hello Pete and All,

Can I easily prevent one specific aircraft from using the LUA Friction solution, and let all others use it normally?

Thanks.

If you have all aircraft in profiles, just use the appropriate [Auto.profile] sections to say whether to load it or not.

Otherwise, add an aircraft identity check at the start of the Lua plug in, restoring instead of changing the values if the aircraft name matches one you don't want it applied to. An event triggered by changing aircraft name would ensure it knows.

Is there a function or something that allows me to get the aircraft name? This is the only thing lacking in order to try to rewrite the script. :-)

Thanks!

You simply read it from FS using the ipc.readSTR function. The data you can read from FS is all listed in the Offsets Status list.   I just searched for it and found:

3D00    256
Name of the current aircraft (from the “title” parameter in the AIRCRAFT.CFG file)

so

name = ipc.readSTR(0x3D00)

PhugoidEffect, do you mind sharing your ready script here, thanks!

Absolutely!

First I'd like to thank Pete for his always great support, and actually I have read the manuals and googled a bit and found the good stuff. Now my script is like below. It seems to be working good for all aircraft.
