Vivian Meazza: This patch is a combined effort by Gregor Richards, Oliver Schroeder, and Vivian Meazza (and code cleanups and improvements by Erik Hofman). It corrects the bug in which a Multiplayer model responds to local inputs, and the view number bug which caused certain aircraft to appear as cockpit only models. It passes remote properties over the net, and all major control surfaces and gear are now animated correctly, providing that the local ~model.xml file contains no leading "/" in the <property></property> data entries. MP objects are now extrapolated using 1st and 2nd derivatives to make their movement appear more smooth. The sim is now halted while a new client joins the net. Known problems with MP are non-display of the remote client under certain circumstances of starting/resetting, and a freeze on starting. These bugs are long standing, and are not addressed by this patch. Special thanks must go to AJ Macleod for his patient testing of this patch over many evenings. We have also moved part of multiplayer into AIModels as part of the ongoing development of MP.

Mathias Fröhlich: The new multiplayer patch with an extension to transmit some properties with the base package. The properties are transmitted in a way that will not immediately brake the packet format if we need new ones. Even if the maxmimum number needs to be limited somehow, that format might work well until we have an improoved packet format which is even more compact and that does not require to retransmit redundant information with each packet. That part is relatively fresh and based on that what Oliver provides on his multiplayer server web page. The properties are transferred to the client and I have modified the seahawks rudder animation property to use a relative property path to verify that it works appart from the fact that you can see it changing in the property browser. The movement is still a bit jerky, but that can be fixed/tuned later without again braking the packet format.

Mathias Froehlich: This patch removes some useless indirection when creating AIModels. It obsolets AIScenario*. AIEntities are just an intermediate copy of an other intermediate copy of an xml file on the way from the ai scenario configuration file to the AIModels. As such the AImodels can now be created directly from the property tree read from the scenario file. This reduces the amount of work needed to add an other AIModel and reduces the amount of copy operations done during initialization. It also moves internal knowledge of special AI models into these special AI models class instead of spreading that into the whole AIModel subdirectory which in turn enables to use carrier internal data structures for carrier internal data ... Also some unused variables are removed from the AIModel classes. I believe that there are still more of them, but that is what I stumbled accross ... Tested, like the other splitouts these days in a seperate tree and using the autopilot for some time, and in this case with a carrier start ...

It also activates fuel flow between User and User aircraft when they are less than 50 ft apart. To participate in multiplayer as a tanker, all you require to do is to use the callsign MOBIL* (where * is some number) on the net. Only MOBIL1, MOBIL2 and MOBIL3 have been assigned TACAN channels, but any MOBIL callsign will be able to give fuel."

Mathias Fröhlich: The new multiplayer patch with an extension to transmit some properties with the base package. The properties are transmitted in a way that will not immediately brake the packet format if we need new ones. Even if the maxmimum number needs to be limited somehow, that format might work well until we have an improoved packet format which is even more compact and that does not require to retransmit redundant information with each packet. That part is relatively fresh and based on that what Oliver provides on his multiplayer server web page. The properties are transferred to the client and I have modified the seahawks rudder animation property to use a relative property path to verify that it works appart from the fact that you can see it changing in the property browser. The movement is still a bit jerky, but that can be fixed/tuned later without again braking the packet format.

Vivian Meazza: This patch is a combined effort by Gregor Richards, Oliver Schroeder, and Vivian Meazza (and code cleanups and improvements by Erik Hofman). It corrects the bug in which a Multiplayer model responds to local inputs, and the view number bug which caused certain aircraft to appear as cockpit only models. It passes remote properties over the net, and all major control surfaces and gear are now animated correctly, providing that the local ~model.xml file contains no leading "/" in the <property></property> data entries. MP objects are now extrapolated using 1st and 2nd derivatives to make their movement appear more smooth. The sim is now halted while a new client joins the net. Known problems with MP are non-display of the remote client under certain circumstances of starting/resetting, and a freeze on starting. These bugs are long standing, and are not addressed by this patch. Special thanks must go to AJ Macleod for his patient testing of this patch over many evenings. We have also moved part of multiplayer into AIModels as part of the ongoing development of MP.
