# A logistics vessel is ONE vessel, so it looks the same wherever it is drawn.

# #216 made transporters and repair drones fly out from the mothership as
|
||
|
|
# ordinary vessel deliveries. A delivery draws the hull off the vessel
|

|
# DEFINITION; the stationed nodes each drew a copy written into their own
|
||
|
|
# script. The copies had drifted - the transporter's definition declared no
|
||
|
|
# hull at all, so one in flight was an empty polygon, and the drone's two
|
||
|
|
# shapes differed by a couple of units - which is why a transporter changed
|
||
|
|
# shape the moment it was assigned.
|

|
# Covers:
|
||
|
|
# A. every vessel that can be delivered declares a hull to be drawn by
|
||
|
|
# B. the stationed node draws that same hull, not a second copy
|
||
|
|
# C. and the colours agree, so it does not change livery either
