Simulation fixes

  • I think I finally figured out how to prevent sessile feet on the side. This bug caused numerous problems, like plants multiplying, corrupt saves and missing models in the species list view.

Added steepness of the terrain and how limbs differ in what steepness they support

  • Also calculate the steepness underwater, as visible on the steepness map

  • Got the steepness map also working mid simulation

  • Added a maximum steepness statistic to limbs, editable in LimbStats.yaml

  • Changed the limb stats view to show this new steepness statistic in the animal editor

  • For the requirement panel when placing an animal, instead of just 'water', 'land' and 'steep', added various descriptions like 'mild slope' and 'cliff'

  • In the simulation, made sure animals cannot walk on terrain too steep for them, and also don't lay eggs there

Fixes for editing the terrain mid simulation

  • Fixed problem where the first drawing was always linked to an existing continent, instead of to a new one

  • Optimized drawing and moving continents (most noticeable when moving continents mid simulation)

Fixes for drawing statistics mid simulation

  • Prevented negative edit circle sizes (thanks azul1462!)

  • When drawing manual stats, prevented the colors always snapping back to the terrain colors (thanks azul1462!)

  • Set the initial value of the slider to 0.5, and made sure this reflects the actual initial value when painting

  • Fixed the slider snapping to incorrect values after releasing the mouse button

  • Fixed the draw tool sometimes missing the tile exactly in the middle of the circle

  • Optimizationdecreased the time the game hangs after drawing statistics

Polishing upright animals in the animal editor

  • Designed horizontal/vertical toggle icons

  • Redesigned the general animal traits view, so the horizontal/vertical toggle fits better

  • Made all changes to the torso shape (diameter, displacement) less extreme when switching to the upright form

  • When switching, also update the mount point indicator positions and sizes

  • Fixed problem that bodyparts on the front ended up on the back when switching posture

  • Fixed problem where some body parts that ended up inside the torso when switching posture were not removed, while others that did not end up inside were (thanks PlayerDJNB!)

  • For body parts that base their appearance based on position, made sure upright animals now always show the correct model

Working on limbs

  • Fixed incorrect evolution tree lines going out of frame in some cases

  • Added parachute like wings to the arthropod limb tree

  • Improved the kangaroo legs models to better fit upright postures
