Ad Astra Cargo Rockets
by BillBodkin
Ad Astra Cargo Rockets is a Fabric add-on that lets rockets carry cargo between planets without manual control, driven by CC:Tweaked computers.
What it does
Automated rockets carry cargo between planets. A CC:Tweaked computer controls a rocket and its launchpad through an API: it can launch rockets, manage their inventories and check energy levels. Computer scripts use inventory slot indexes that start at 1, matching CC:Tweaked's conventions.
The API reports errors before a launch goes wrong. A destination planet name that is invalid is rejected, as is a planet string that does not match a known world. Launches are refused when the launchpad lacks enough energy, or when the rocket's tier is too low for the destination or too high for it to be useful there. Each function takes a rocket slot or a launchpad slot as an integer.
The mod requires a planetary rocket base add-on, and it runs on the client and on the server. It is published for Fabric only, for 1.20.1, with rc.3 as the latest file on the beta channel. The mod is open source under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public.
