PATCH NOTES

FEATURES
Increased creature autonomy: after learning first to swim and then to seek out targets, creatures enter a life stage in which they are more autonomous in their decision-making, attempting to fulfill their individual needs.

The following new behaviors are now available to creatures:

  • Finding shelter and resting
  • Building nests
  • Feeding on insects on the water surface
  • Gathering food to bring to their offspring
  • Playing and socializing, chasing each other or knocking stones around
  • Swimming in schools
  • Bioluminescence
  • Song
  • Pitch and volume envelopes for each note in a song are specified in the genetic code, so songs will evolve as the species does.
  • Reworked creature fertility and energy so that the odds of survival and number of offspring is less influenced by random factors.
  • Creatures now remember the locations of food seen while exploring.


FIXES

  • Update translations for the new text added in the update.
  • Improved line-of-sight checks before creatures resort to pathfinding to prevent cases where creatures swim far up because their target is behind a small bump.
  • Fixed some errors with line of sight checks that could result in creatures not seeing food/mates that actually should have been visible.
  • Fixed error where color comparisons could be incorrect when checking how well a creature blends in with its environment.
  • Fixed error where bilateria spawn preset had incorrect 4x lifecycle count by default.
  • Fix: On rare occasions, creature models can freeze and end up floating permanently in the water.
  • Fix: On rare occasions, plant models can freeze and be unremovable by the player.
  • Fix: messages about species maturation and nonviability remain on the screen while the game closes down after exiting
  • Fix minor errors that could occur when the plankton cursor was outside of the game region and when displaying traits for certain creatures, which could impact performance.
  • Fix error that could cause some saves to fail to load.
  • Fix: boosting a creature creates offspring that are not initialized properly.
  • Fix error causing degraded performace and incorrect behavior when creatures who are playing with a rock knock it out of the ecosystem boundary.
  • Fix: creatures forget what they were doing upon loading a savegame.
  • Fix: all gifts turn into mushrooms upon loading a savegame.
  • Fix: when mushrooms are picked up to use as a gift, they are not held in the mouth but seem to float outside of the head.
  • Fix error where the games by friends panel would not disappear when it was supposed to.
  • Fix error that can occur when a creature is recovering from a staggered state and actively targeted by another predator.
  • Fix minor errors with bioluminescence and the creature editor.
