It's a stock mission or u built on FMB?

A stocked mission,in the folder Multi/Dog Flight

IIRC there can be a bug in a mission: number of aircraft for a particular spawn point set to 0. It defaults to 0 and mission makers forget to change it very often. You can check it out in FMB.

Try other mission or user-created missions found in the FMB section of this forum or @ airwarfare.com . Stock MP missions are not very useful anyway.

e...Thanks a lot.
I have tried to make a FMB mission,but there is still some problms.
If I select England and Germany as red and blue first,I can`t add a plane,but I can add any other point in the map.
If I add a plane first,I can`t select red and blue.
Why?Still bugs?
How can I make a Multi Mission?

Sorry I can not understand what you mean.

Download someone else's mission from the MP or FMB section of the forum, open it in FMB and study how it is done. Maybe it helps.

OK,I`ll try.
Thank you very much.

Hi. When you tried the hosting, the realism settings is "full realism"?
If yes, turn off the "select aircrafts, change aircrafts, etc. settings. All of them. It may causes aircraft selecting problem, like you wrote.

I forgot the realism settings.I`ll check it later.Thank you.

The default port is 27015 not 27016... As VO101Tom said, in Realism options there a box in the middle at the bottom - untick all six options in that box.

Check ports on router and firewall/antivirus.

To rule out "bad" map making run one of the stock multiplayer missions first.

OK,thank you,I`ll try later what you said in realism options.
I have set the right ports on router and turn off the firewall/antivirus.
