Hello ,
I resubmit my patch .
This reason of this patch is to have a better behavior of flightgear when you
fly
in multi screen configuration with multi-player mode .
When you setup a multi-monitor configuration you have multi instances
of flightgear ( see http://www.inkdrop.net/dave/multimon.pdf ) .
Currently i play with the bo105 , without patchs i had bad second effects .
1) A part of instruments are not synchronized , and the animation too .
It's the why i had wrote :
patch_001_helico.v4.txt
=> add some helicopter specifics fields in the layer commnunication
between flightgear instance .
patch_006_netfdm_gear_agl.txt
=> add another field in the layer commnunication between flightgear
instance .
2) On the second screen , i dont see multiplayer .
A small solution to solve the problem was to resend the packet coming from
the multiplayer server to the other instance of flightgear .
- patch_002_multiplayer.txt
3) Scenery objects are not syncronized between differents instance of
flightgear,
and i prefer to see only real player .
So i had a option to disable all ai objects except multiplayer .
- patch_003_no_ai_except_multiplayer.txt
In attachement 4 patchs for the cvs of fligtgear .
Who can push this patch in the cvs ?
