Been quiet for a bit because I’ve been focused on getting the Astra 0.1 demo into a state I’m actually happy to ship. A lot of the systems I’ve been posting about are finally coming together into something that feels like a game. No multiplayer yet, that’s coming soon. Here’s 30 seconds of where it’s at. Try it yourself at astra.game

Interstellar travel is now working for astra.game Star systems can now be linked through warp gates, letting the player travel seamlessly from one system to another. Visuals are still very WIP, but the system itself is working. Coming in the next release. #indiedev #indiegamedev #gamedev #buildinpublic

Cargo hauling one crate at a time got a bit old, so we added a trolley! Those crates don’t stand a chance now. astra.game #indiedev #indiegamedev #gamedev #ai #buildinpublic

Small update on hab/outpost generation. We’ve updated our kit to support even more possibilities. This gives us a lot more flexibility when generating different structures and layouts for astra.game #indiedev #indiegamedev #gamedev #buildinpublic

Day 17 of building the space sim we all got tired of waiting for. Sorry for the lack of regular updates. We’re fully focused on getting the singleplayer demo ready for release next week. I did find some time for Procedural Cliffs though. Turns out you don’t need 5 versions of planet tech if you get it right the first time! astra.game #indiedev #indiegamedev #gamedev #ai #buildinpublic

Day 15 of building the space sim we got tired of waiting for. After a few unexpected detours, I’m back to preparing for our demo in a couple of weeks. On the menu today: fully procedural habitation modules (still WIP).

Interiors are swappable too. Still very low-poly at the moment, but that should improve quickly as we flesh things out.

Day 14 of building the space sim I got tired of waiting for. A forest in this game doesn’t spawn because I painted a green biome on a map. Before anything grows, the planet runs through 45 data layers: terrain → drainage → climate → wind → water cycle → rivers → geology → soil → biome. Every layer affects the next. A mountain can push moist air upward, cause rain on one side, leave the other side dry, and that difference carries through into soil moisture and eventually the biome.

Day 13 of building the space sim I got tired of waiting for. We’re one step closer to our first major milestone: a fully working cargo-hauling job between two planets in a server-meshed environment. The site is live now too: astra.game If you want to support development, we’re accepting donations. As a thank-you, supporters will get some cosmetic, strictly non-P2W rewards. Still a long way to go, but it’s starting to feel real. 🚀

@BoredGamerUK @SpaceTomatoGG @Morphologis @TheNOOBIFIER1337 @cmd_Terada @SuperMacBrother @SaltEMike @greasykhaleesii astra.game is rapidly becoming something to keep an eye on. A new universe is taking shape.

Day 10 of building the space sim I got tired of waiting for: astra.game Sorry this took a bit longer. I present to you server-meshed localized physics grids. A problem that became years of R&D at another company took us just a couple of days to get running. - One player is piloting the ship. - Another is running around inside the cargo hold. - A third is watching from the ground. If you're about to buy another ship, maybe consider funding Astra instead. We're actually building a working game.

Day 8 of building the space sim I got tired of waiting for: #Astra. Did a lot of infrastructure work and website work today, none of which is particularly interesting to show off here, so instead here’s some progress on the cloud tech. Still not quite production-ready, but it’s getting there. Join us at astra.game! #indiedev #indiegamedev #gamedev #ai #buildinpublic #StarCitizen

Day 7 of building the space sim I got tired of waiting for. Spent most of today dealing with the less glamorous parts of building an actual game, but still managed to get real-time, volumetric, planetary-scale clouds taking shape (taking a small break from networking). Very early, but it already makes the planets feel completely different. Come help shape development at astra.game #indiedev #indiegamedev #gamedev #ai #buildinpublic #StarCitizen

Day 6 of building the space sim I got tired of waiting for. 100 players, 3 workers, one continuous world. Authority transfers when a player crosses a boundary and the client never sees it. Server meshing works. Three or thirty, the code does not care. #indiedev #indiegamedev #gamedev #ai #buildinpublic #StarCitizen

If you’re new here: I’m building Astra, the space sim I got tired of waiting for. Custom C++ engine, seamless planets, ships, interiors, persistence, multiplayer, large-scale simulation, the whole nine yards. No 14 year roadmaps, no ~$1B in funding. I post what actually works.
