GeckoLib v5.5.4

Bug Fixes

  • Fixed query.life_time being negatively inverted
  • Prevented GeckoLib crashing if attempting to animate with an empty animation
  • Fixed GeckoLib crashing on newer NeoForge versions
  • Fixed GeckoLib crashing when attempting to send a default RawAnimation over network
  • Fixed GeckoLib not evaluating nested ternary expressions properly
  • Fixed DieRollIntegerFunction giving the wrong name when asked
  • Fixed a crash caused by serverbound GeckoLib packets (we don't have any at the moment anyway, but still)
  • Fixed NeoForge's entity RenderState extensions being ignored by GeckoLib
  • Prevent GeckoLib crashing if attempting to retrieve an incorrectly typed DataTicket
  • Fixed left-handed GeckoLib entities using first-person render context for third person offhand items
  • Fixed uppercase Molang queries not being recognised by animations
  • Fixed various whitespace issues with Molang expression parsing
  • Fixed single-element vector arrays in Molang expressions erroring out
  • Fixed custom GeckoLib resource loaders disabling themselves
  • Fixed GeckoLib resource loading crashing out if a mod has both a suffixed GeckoLib resource file and a non-suffixed one with the same name
  • Fixed synced singleton animatables (mostly items) colliding with another in very rare occasions
  • Fixed RawAnimation not necessarily comparing as equal in very rare occasions
  • Fixed RawAnimation.Stage not necessarily comparing as equal in very rare occasions
  • Fixed KeyFrameData not necessarily comparing as equal in very rare occasions
  • Fixed the RawAnimation#thenWait waiting 20x too long
  • Fixed easeinquint not being quint
  • Fixed AnimationController#hasAnimationFinished not working properly
  • Fixed a potential collision or crash caused by multithreaded handling of animation parsing or modloading
  • Fixed a potential crash from reloading resources with GeckoLib animated textures present
  • Added some safety checks for ItemArmorGeoLayer to prevent crashes/errors from invalid setups
  • Fixed DyeableGeoArmorRenderer rendering bones at the wrong location
  • Fixed GeckoLib crashing the entire game if a mod attempts to animate something in an invalid way
  • Fixed animations with out-of-order animation keyframes not being sorted when loading in
  • Fixed a potential multi-threading crash or corruption from SyncedSingletonAnimatableCache
  • Fixed a potential crash caused by unexpected values in DieRollIntegerFunction and RandomIntegerFunction
  • Fixed SyncedSingletonAnimatableCache acting as a slow-burning memory leak by retaining every id indefinitely
  • Fixed Molang expressions with empty groups '()' erroring out with little information when parsing
  • Fixed top-level bones with locators throwing an error for each one on load
  • Fixed GeckoLib's resource loading incorrectly telling Minecraft to move it on-thread before it's done
  • Fixed multi-stage animations with a transition time not transitioning properly
  • Fixed math.atan, math.acos, and math.asin calculating tiny values and being wrong
  • Some rendering performance improvements
  • Fixed GeckoLib clients requiring NeoForge servers to also have GeckoLib installed
  • Fixed variable assignments in Molang not parsing properly if accompanied by a tenary or sub-expression
  • Added operator symbol aliases for && and || - although the bedrock spec doesn't support this technically
  • Fixed negative math function results not parsing properly in molang
  • Fixed some higher-level molang operators having completely incorrect precedence indexes
  • Fixed some other molang parsing issues
  • Misc cleanup
