Project Avion: build it, fly it, smash it

In-game features

Everything is a machine

No preset vehicles, no pretend physics. You decide what the thing is, and the world decides whether it works.

Build block by block

Drag parts out to any size, snap them onto a precise grid, mirror whole sides, group them, and undo anything.

Editor

Real aerodynamics

Lift and drag are worked out from the shape you built. A wing flies because it is a wing.

Physics

Moving parts

Engines, servos, pistons, bearings, suspension, tracks, and gears that mesh and turn each other.

Mechanics

Sensors & logic

Wire sensors into logic, switches and buttons. Build an autopilot, a turret that tracks its target, a door that opens itself.

Logic

Water that pushes back

Waves, buoyancy, wakes and splashes. A hull floats on the air trapped inside it, so shape matters.

Water

Destruction

Blocks take damage, crack and break away. Crash hard and the ground takes a dent too.

Damage

Multiplayer

Build side by side with friends, then race, fight or fly formation with what you made.

Together

Building

From one block to a working machine

The editor is built to stay out of your way. Here is how a build comes together.

01

Drag out any shape

Pick a block and pull it out to the size you need: a beam, a plate, a whole hull, in one drag. Everything sits on a precise grid, so parts meet cleanly.

02

Wire it up

Switch to the blueprint view to see how your machine connects. Link engines to wheels and sensors to logic by drawing a line.

03

Tune every part

Select a part to open its settings: engine power, steering, suspension, the keys that drive it. Small changes, big differences.

04

Test it in the wind

Turn on the test wind and watch how the build reacts before it ever leaves the ground.

05

Keep what works

Every creation goes into your library with a picture and its versions, ready to load back in a couple of clicks.

Drag to size

Planets

Leave the ground behind

Take off from a planet's surface and keep climbing until the sky turns black. Planets are round, with their own gravity and air, and the space around them is full of things to fly to.

Real gravityDown always points to the planet's centre, wherever you are on it. Fall back to the surface, or fly fast enough to stay up.
Air that thins outWings grip thick air near the ground and lose it as you climb, so a plane and a rocket need different designs.
Moons, rings and asteroid beltsMoons hang in the sky, and rings and belts are full of rocks to weave through.

From the clouds to orbit

Drifting through an asteroid belt

Modding

Make it yours

Project Avion is built to be modded. Write Lua scripts that add blocks, tools, maps, interfaces, sounds and effects, with no game engine to install.

Safe by design. Mods run in a sandbox and have to ask before they do anything risky. You decide what they may do.
Multiplayer ready. Join a modded server and its mods download for you, after you agree.
Documented. A full guide, an API reference and example mods to take apart.

-- scripts/main.lua: a panel in the corner of the screen
log.info("Hello from", mod.name)

local panel = ui.panel{ anchor = "top-right", padding = 12 }
panel:style{ ["border-radius"] = "6px" }
panel:addNew("Label", {
  text = "My first mod is running!",
  style = { color = "#f59e0b" },

-- F7 shows and hides it
input.bind("F7", function()
  panel:set("visible", not panel:get("visible"))
  notify.toast("Panel toggled")
end)
