Minecraft with physics. Vehicles you build.

Build vehicles from blocks on Astra. Use Create and Aeronautics to change a design, test it in motion and carry resources between builds. Astra is a free Minecraft Java server.

What you can do in the game.

01 / Physics and vehicles

Give the vehicle a job

A cargo vehicle needs access to storage; a prototype needs a clear testing area. Decide on dimensions, controls and loading space before building the body. A machine that cannot fit through the base entrance needs a layout change, not just different decoration.

02 / Astra

Test it under load

The mass and placement of parts affect a physical build. Compare an empty vehicle with a loaded one when steering, accelerating and stopping. Change one part at a time so you can tell which adjustment improved its behaviour and which caused a new problem.

  1. Decide on cargo and vehicle dimensions.
  2. Compare empty and loaded handling.
  3. Build access and parking next to storage.
Server rules
03 / In a shared world

Leave room for maintenance

Reserve a place to assemble and repair vehicles, keep replacement materials nearby and leave access to the controls. On a shared base, agree who uses each vehicle and where it should be parked. Heavy prototypes belong away from other players' buildings.

Before you join.

Why use a separate testing area?

A clear area lets you check steering and stopping away from the base. Once the empty vehicle works, repeat the route with its intended load.

Do I need to install physics mods separately?

Install the complete Astra pack through MARALYS. Its required physics components are included, so you do not need to select compatible versions by hand.

Why start with a small vehicle?

A simple build makes problems with the hull, component placement or controls easier to isolate. Add new systems after checking the basic vehicle.

See you on Astra.
