This is a ground transportation foundation for my series of modular late-21st century space systems. Required downloads in addition to this are:
Vinka's spacecraft3.dll
My LSTS Cargo Lander
An additional copy of my arm addon is included; it is safe to overwrite the arm mesh if you have downloaded that addon.
Operational tips:
1. Cargo modules should begin their "life" in "Orbiting" status, as is illustrated in the included scenario. Beginning them in a "Landed" status will result in their dropping instantaneously to the surface when released from an attachment, which defeats the purpose of simulation of transferring them from the surface to space.
2. Transferring cargo from one vehicle attachment to another on the surface is best done while reducing the simulation to minimum speed. This gives you time to switch to the "receiving" vessel, activate the attachment function and trigger the attachment.
Known bugs:
1. The "receiving vessel" attachment will "inherit" misalignment. If you save and restart a scenario after transfering a cargo module, it will be properly aligned as an attachment.
2. Some vessel attachment and arm functions are not properly displayed in the information line provided by spacecraft3.dll. The attachment and arm data display will only "flicker" on, but they otherwise function properly. I believe this is caused by the "Landed" status of the parent attachment vessel.
