Changelog

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

  • Add SizeOverLifetimeModifier.
  • Add PositionCircleModifier to allow spawning from a circle or disc.
  • Revamped spawning system:
    • SpawnMode is gone; Spawners are constructed with associated functions new, once, rate, and burst.
    • Spawners can be reset with Spawner::reset. This gives control over when to spawn a burst of particles.
    • Spawners can be activated or deactivated with Spawner::set_active.
    • ParticleEffectBundles can be initialized with a spawner with ParticleEffectBundle::with_spawner.
  • Implemented ToWgslFloat for Vec2 / Vec3 / Vec4.
  • Implemented ToWgslFloat for Value<f32>.
  • Derive-implemented PartialEq for Value<T> and Spawner.
  • Implemented randomization for randomized spawning parameters
  • New force field effect:
    • Add ForceFieldModifier to allow attraction or repulsion from point sources.
    • Add ForceFieldParam in both the modifiers and the particle update shader.
    • Add force_field example showcasing a repulsor, an attractor and the conforming to sphere functionality.

Changed

  • Renamed the ToWgslFloat trait into ToWgslString, and its to_float_string() method into to_wgsl_string(). Also made the trait public.
  • Position modifiers now use Value<f32> for velocity to allow for random velocity.

Fixed

  • Fixed depth sorting of particles relative to opaque objects. Particles are now correctly hidden when behind opaque objects.
  • Fixed truncation in compute workgroup count preventing update of some particles, and in degenerate cases (capacity < 64) completely disabling update.
  • Made the GradientKey<T>::ratio field private to avoid any modification via Gradient<T>::keys_mut() which would corrupt the internal sorting of keys.

[0.1.1] 2022-02-15

Fixed

  • Fix homepage link in Cargo.toml
  • Bevy 0.6.1 fixed build on nightly, thereby fixing docs.rs builds

[0.1.0] 2022-02-11

Initial alpha version. Lots of things missing, but the barebone functionality is there. See the README.md for the list of planned and implemented features.
