Items and cargo fluid live in the rocket's own inventory/tanks. Pipes and hoppers connected to the launchpad still load/unload them automatically while the rocket is grounded, or you can do it by hand via the rocket's inventory screen (right-click it). This script just waits for energy/fuel and triggers the launch.
Safety check: if leftover cargo wasn't unloaded by hand last cycle, hold the rocket on the pad instead of launching it again with old items still aboard.
Origin â
Destination â
Unchecking "Load" still unloads/drains at that end â it only skips loading new cargo before launch.
Transfer Mode
Simple: bulk transfer. Manual: slot-by-slot.
LOAD (pad â rocket)
UNLOAD (rocket â pad)
Cargo Fluid Load
Hold the rocket on the pad until the cargo fluid tank reaches a target amount before launching.
