Eliminate Manta's movement

[Tribaja]

I mean a ship moving in space wouldn’t function like a ship moving in water, it would just be a scrolling background since there’s no drag to stop you from continuing forward.

The only way I could see it working and looking decent is maybe if pods are tied to the background, while people aren’t?

With how interstellar and even interplanetary(depending on destination) travel works, the most practical approach(assuming you care about travel time and that you aren't just doing a flyby) with anything other than magic FTL/trying to aerobrake in the stellar corona or even the upper layers of stellar atmosphere/planet's atmosphere is to constantly be either accelerating or decelerating in order to cut down on travel time and to keep the G's at acceptable levels.

So you accelerate 50% of the way and then turn the ship around and slow down the rest of the way, both probably at 1G for artificial gravity. This mostly applies to fusion engines though since they have a high enough efficiency to keep burning for such long durations at high power.

So you could have movement relative to the ship even in space if we assume that the ship maps are in transit. A ship in orbit is another thing though.
