I wanna suggest to add something called na CloackDevice for ships, this would be na multiblock structure for ships.
How would it work?:
So basicaly, it would require some special type of fuel, in a large quantity, to turn your ship into an invisible ship, maybe we could use barrier blocks or something like that, This Cloack Device would require the same fuel over and over and over again to keep cloaked.
This would keep ship invisible and out of the contacts, and maybe hide the player on dynmap.
wouldnt that be to OP?:
No!, because while cloacked we could not fire weapons, we could not hyperdrive, the ship would be slower and the shields would be off (if incase someone finds us they could shoot) [these are just exemples, there might be other downside ideas].
What fuel could we use??: idk, maybe add another custom item?.
How could we activate/deactivate it? maybe an command?
