(sorry if hard to read so here you go-)

purple: well that depends on the type of ship

the Skeld Class and Dropship Class ships have AGG built into the floors

Explorer Class ships also use AGG for there gravity

the Orbitor Class ships use a spinning motion to creat there own artificial gravity

The Alpha Class ships are the largest Class of ships ever built by Crewmates, the only one which ever worked is called the Starburst (only two have ever existed) use a more complex system to create there gravity. but it's large size also helps it create its own gravity. and the unique floors help with much easier movement
