Major simulation change


If an animal is in a location that contains food, it will no longer leave that location until all food is gone (except plankton, which requires swimming through). This makes it a lot easier to keep various animals alive, addressing a recurring complaint... but also leads to crowded environment (and, following that, possibly low FPS) more quickly.

Thanks Luka159, Generaldisblief, Wind_kaffee!

Various changes to make the simulation easier to understand

  • When placing down organisms, a minimalist version of the requirements panel is shown floating near your cursor
  • Took the 'will survive here' text out of the requirements panel
  • Set the maximum mutation rate to 35%, as higher mutations only cause a lot of small new subspecies that never gain enough traction to become full species
  • The time jump view now shows mutation events, so you know evolution is happening even when there are no new species
  • Food types icons now have a tooltip, explaining what they are and how they work
  • Added various tooltips to the animal editor
  • Redesign the underwater speed stats in the animal editor to be easier to understand at a glance
  • Sessile animals no longer show potential (but unused) movement statistics, which was confusing to players (thanks UltraNeonGodPet, Slurp!)

Animation fixes

  • Only show the egg laying animation when the animal is actually laying the egg, not already when it wants to
  • To prevent aquatic animals floating perfectly frozen sometimes, immediately start showing the aquatic idle animation when it's not playing any other

Fixes for terrain textures

  • Season changes no longer cause terrain to becomes a single color (thanks Cody_beaver!)
  • The planet editor no longer forgets to highlight continents after doing it once
  • In the planet editor, when editing seasons and THEN drawing more land, this new land is no longer incorrectly made part of previous continent

Misc

  • Lowered fungus speciation threshold (thanks, Jotbe83!)
  • Newly added animal models now get a random rotation, so they're not all facing the same way

I often forget to read comments below release notes, so if you have questions, suggestions or bug reports, feel free to reach out via the Steam forums or [email protected].
