More work on animation

  • Added sleeping animations: animals squatting, moving head down and to the side

  • Added egg laying animation (best visible in animals with a tail, because they move it up)

  • Optimized specializing animations to player designed animals, and made it possible for an animation to only affect the first limbs (instead of all of them)

  • Changed animation where tailless aquatic animal swim with their fins: they now only move the first set of fins

  • More natural flying animation: made downwards wing movement faster and upwards wing movement slower

  • Made undulating swimming animation symmetrical

Working on limb body parts

  • Added animation weights to 'ocean floor walker', 'filiform', 'hopping', 'spindly' and 'swings between branches' limbs (which reveal they need a separate set of animations)

  • Went over all limb stats in detail for a first balancing iteration

Fixes for seasons in the planet editor

  • Previewing seasons in the planet editor now shows the correct stats and climate zones (thanks azul1462, ultraneongodpet)

  • Going to the season editor no longer toggles the planet editor to manually drawn statistics

  • Turning off seasons now removes the season indicator

  • If you are looking at another season than season A while turning off seasons, update the terrain overlay

Other planet editor fixes

  • The correct map editor tool button is already selected when you enter the editor

  • Fixed the continent highlighting textures carrying over to a new game session (thanks azul1462, Taylor Lilius, DayzeDaisy!)

  • Made it so the planet editor always uses gravity for planet size in spherical mode (rotating planet), but map size when showing the flat map view (thanks saralb123!)

  • Adding planet rings when manually drawing stats no longer causes the planet editor to freeze

  • Increased default deep ground water (thanks Ultraneongodpet!)

Small UI fixes

  • Made it so pressing ESC when something else is open first removes that thing, preventing situations where it overlaps with other UI

  • Prevented UI overlapping when a dropdown is open and you click an organism

Sessile animal fixes

  • Turns out my fix for the ballistic mouth broke all other mouths on top *facepalm*. Now they all work. (thanks Ultraneongodpet!)

  • Fixed problem where lowering the terrain height did not update how high sessile animals grow

  • 'Slow moving tube feet' no longer swim around like they're not sessile at all (thanks Cody beaver!)

Misc

  • Updating the terrain mid simulation while the camera is underwater will no longer lead to unexpected moiré patterns on the ocean floor
