(Working) Landable Ships
Also this reupload is technically official since I got in direct contact with TerrariaMan, who listed this specific steam reupload on his mod page.
Penguin Pete sells 5 new products, as seen in the image below.
The Ship Controller is your primary item. This enables you to deploy your Planetary Ship, as well as manage its current state alongside fuel and customizability.
Ship Chips are addons to modify the background of your Planetary Ship. They contain unique themes that add style to your Planetary Ship. While two are sold by Penguin Pete, the rest (and significantly more valuable chips) are found throughout the universe by rare chance.
Ship Fuel is the fuel source required to keep your Planetary Ship running. If fuel runs out, you are immediately teleported back to your main ship, unable to deploy your Planetary Ship unless it is fueled above 0%.
Possible Bugs
If your ship is still there despite deploying it back to your main ship, or you cant drive your ship, then use this command with your cursor pointing at the ship "/entityeval vehicle.destroy()"
A crash may happen during teleporation but it’s usually rare and always harmless.
Now then, you’re prepared to roam the planets the way you expected!
