is it possible to spawn a Spacecraft3.dll vessle out of a cargobox
ucSpawnModule = [NAME OF VESSEL&DIR]; name of vessel config to spawn once cargo released.
ucSpawnDelay = 0 ; delay in seconds of module spawning after cargo
ucSpawnCondition= 3 ; 0=Landed 1=Not landed 2=Always 3=unpack by UMmu

ucSpawnModule = UCGO\bin\FireworkRoket2
it looks like:
and i get the error massage that FireworkRoket2.cfg is not found. the data is like a spacecraft3 file an *.ini file, so how can i spawn this vessle i´ve copied the Spacecraft3.cfg into this directory too and tested it but it also didn´t work.Code:ucSpawnModule = UCGO\bin\FireworkRoket2
ucForceName = Firew2 ; Force object name when cargo is released max 6 char.
Module = UCGODynamicCargo ; if this cargo is active (chute,unpack, module etc)
Mass = 30 ; mass of content in kg
MeshName = UniversalCars/UCGOProbePacked ; Box mesh name (packed cargo)
UcDescription = Auto unpack Firework (10s) ; description
ucSpawnModule = UCGO\bin\FireworkRocket2 ; name of vessel config to spawn once cargo released.
ucSpawnDelay = 10 ; delay in seconds of module spawning after cargo release (max 600)
ucSpawnCondition= 2 ; 0=Landed 1=Not landed 2=Always 3=unpack by UMmu
UcSpawnItemNbr = 2 ; Number of item carried in box
I had a fast look: with cargo/module one should have a dedicated vessel config and unless I'm wrong spacecraft3 load only vessel's parameter based on the "name" of the object eg: DG-01:" Also config must absolutely located in "vessels" config directory which is not the case of spacecraft3.cfg (in fact there is no specific vessel "config" in sense of orbiter)
Last cargo allow multiple spawn which is not possible with the "ini" "name" based system. Orbiter doesn't allow two objects with the same name. (You can cheat editing scenario but it's a call for problems)
Now maybe there is a way of cheating to spawn a SC3 vessel but I don't know it and if you spawn two cargos the ini file will be not found (as UCGO check/change cargo name to avoid problem)
Maybe you should ask vinka if he plan to work on SC4/2010 to allow "per vessel" config with parameters into vessel config as UCGO cars instead of ini files. Grabing parameters from those config is pretty easy in Orbiter. (Martin planned that user would put their own parameters in their vessel config)
Hope this answer ?
