PATCHNOTES
0.4022 beta
- added link to the new custom system guide
- renamed "Force terrestrial planet" to "Force habitable planet" to make it clearer what it does
0.4021 beta | Eridanus
- added atmosphere and temperature simulation!
- added surface liquids
- added geological activity and life
- civs added, and are now more common the older the planet is, as a simulation of the 'sapiozoic' phenomenon theorized by Leriendil where civilizational influence 'builds up' on the planet over time
- added seeds (pseudorandom generation) (unrelated to seeds (botany)) - system's seed is now logged to console
- added a tickbox to force the generation of systems with habitable worlds
- greatly improved visuals for planets
- added random name generation (the same as walkersysgen), Salibe is now the placeholder name for when a planet is unnamed
- buttons made a lot more compact
- fixed years
0.4011 alpha | Gemini:
- system diagrams! (Shows all current info on each planet)
- binary and even triple stars!
- full JSON editing, customization, download and upload support (ripped from the original walkersysgen)
- no longer in pre-alpha
v0.4001 alpha | Orion:
- pre-alpha generator released
- doesn't even have a system diagram yet smh
- and all the planets are named Salibe, what kinda generator is this
COMING SOON
0.4031 | Horologium - planned features:
- planetary rings
- rotation periods and tidal locking
- binary planets and unterplanets
- hopefully full release of 0.5 at this point, depends on what I remember to add
FAQ
Where are the save/load options?
Show the JSON editor, that will reveal them. The save/load options now interface directly with the customizer.
The JSON area is tiny!
You can scale the JSON textarea by dragging on the bottom right. This is actually true of HTML textareas in general.
.SOLAR? What even IS that?
It's literally just a JSON file, labeled SOLAR in order to mark that it's a solar system for Periapsis.
Will we be able to migrate systems from WSSG?
Probably not. It's not on the roadmap currently, at least.
What's an AU☉?
A measurement of received stellar energy that scales proportionally to the distance from the star. In short, it's how far Earth would need to be from the star to receive the same amount of energy it does from the Sun IRL.
What's a seed?
A seed is the base number the app uses to generate a system. The same seed always gives the same generated system, assuming the chance for life and whether to skip non-habitable systems are set the same. For example, the seed 69420 on v0.4021, if "force habitable planet" is set and the value 0.69 is used for the chance of life appearing on a habitable planet, yields a system with a civ homeworld.
Why aren't there any planets with oxygen?
The atmosphere composition entry only lists the gas that makes up the majority of the atmosphere. Oxygen can be inferred based on the presence of Phanerozoic life. However, I don't really see the significance of a planet's atmosphere having oxygen.
