CosmosEngine is a space simulator that allows you to explore entirely procedural universes with millions of unique star systems (1,048,576 to be exact). Each universe is also based off of a seed, so you can revisit your discoveries after closing the project. Discuss the game and share your discoveries here! https://scratch.mit.edu/discuss/topic/894603/ (This game is still under heavy development. There will be bugs, clearly missing content, and overall be rough around the edges.) Use TurboWarp if you want high render distances to run smoothly: https://turbowarp.org/1107646139 ––––––––––––––––––––Controls––––––––––––––––– Click on an object to select it WASD to move Z/X to slow down/speed up (hold space to go faster) R/F to zoom in/out (hold space to xoom faster) G to center on a selected object 1, 2, and 3 to quickly zoom in to different scales Move your mouse to the far right to access sidebar ––––––––––––Planned/considered features––––––––– Features ending with a question mark are uncertain as for if they'll ever be added. -Much more planet diversity -Atmospheres and seas (atmospheres added in 1.2) -Moons and dwarf planets (dwarf planets added in 1.1) -Special star types (black holes, white dwarves, supergiants, etc.) -Life -Rogue planets and brown dwarves -Asteroids and comets -Rings -One shared universe and multiplayer -Mobile support -Binary/multiplicative star systems? -Civilizations? -Galaxies? -Procedural terrain? -Nebulae? –––––––––––––––––––––Tags––––––––––––––––––– #Space #Universe #Generator #SpaceEngine Universe generator
-Huge inspiration from SpaceEngine -Partial inspiration from Universe Explorer 2 https://scratch.mit.edu/projects/886615877 –––––––––––––––––––Changelog–––––––––––––––– 1.3, "Calibrations" (August 25, 2026) -Mainly optimizations and improvements to the games code, including reworking planet rendering, the text engine, and how planet info is stored -Block count decreased from 5,855 to 5,238 (an 11% decrease!) 1.2, "Cloud seeding" (July 19, 2026) -(MAJOR) Reworked universe generation to use chunks and seeds -(MAJOR) Added very basic atmospheric models -For the time being, removed dwarf planets and filter -Optimized orbit rendering some more -Fancified title screen -Stars that are not visible from your current zoom cannot be clicked on -Added new object info panel -Hopefully fixed some text not unloading when you select a new object -Resharing project in hopes that it gets indexed 1.1.4 (June 28, 2026) -Replaced all generation variables with lists -Semi-major axis in filter is now displayed in AU -Added highlight to settings buttons 1.1.3 (June 21, 2026) -Added measuring tool -Slightly optimized orbit rendering -Fixed stars and planets being smaller then they should (thanks measuring tool!) -Values for each item are now shown in filter lists -Minor generation changes 1.1.2 (June 18, 2026) -Stars now disappear depending on zoom and their mass -Added more stuff to settings (along with revamping how setting buttons are coded) -Holding space makes you zoom/change speed faster HIATUS 1.1.1 (March 23, 2025) -Added "toggle orbit trails" to settings -Other stuff that's too small for you to care about 1.1 (March 16, 2025) -Added dwarf planet generation -Added settings -Added the ability to search specific planet types in the filter -Planets now have icons when zoomed out enough -Modified quickzooms 1.0.2 (March 12, 2025) -Gas giants around M and K-types are less common 1.0.1 (March 10, 2025) -Hopefully reduced memory usage -Fixed random generation slowdowns -Visual/generation improvements 1.0 (March 9, 2025) -Initial release
