flutter3d_particles 0.7.0

A pooled CPU particle simulation for flutter3d, and the contributor that draws it. Its particles can be a light source, which is the part no other engine on this platform has.

0.7.0

• A burst can light something. ParticleSystem.burst takes an optional source, and a LightEmitter passed there has its glow fed by the burst's particles, then fades and leaves the measured set on its own. Before this a burst's particles were born belonging to nobody, so a muzzle flash or an explosion cast no light however bright its colour was, while the skill in this package said it did. Existing calls are unchanged.

• flutter3d_particles_core is back inside, and Flutter is out. The simulation had been split off so a headless caller could bake a ParticleSystem; the two contributors stayed here because they imported Flutter, for a debugPrint inside an assert and for flutter3d's barrel. They import flutter3d_core now and report a missing shader stage through dart:developer's log, so the whole package is plain Dart and flutter3d_model_core depends on it directly. The public API is the same; an importer of package:flutter3d_particles_core names package:flutter3d_particles/flutter3d_particles.dart instead.

• The pubspec follows. flutter: sdk and the dependency on flutter3d are gone, and the package depends on flutter3d_core ^0.7.0 and flutter3d_hardware ^0.7.0. An application that reached flutter3d only because this package brought it has to name it itself. The tests run under dart test. The archive carries skills/flutter3d-particles-one-draw-call/ for a coding agent, installed with dart run skills@ get.

0.6.0

• Floors, and no code. One pool, one draw call, whatever is in it — byte for byte 0.5.0's. flutter3d and flutter3d_hardware are now floored at ^0.6.0, which is the pair this package's single batch was compiled against.

0.5.0

Breaking. An ease carries its curve.

• KeyEase is a value class holding the shape it applies. Opening the list alone would have been useless — easeShape would have had no branch for a game's own ease. A game writes const KeyEase('bounce', _bounce) and every curve and gradient samples it without this package having heard of it.

0.4.0

• No changes of its own; the version moves with the workspace, whose sibling constraints name a single release. The README's closing section now says what the engine around this package is.

0.3.0

• No changes of its own. The workspace is released as a set, in the order ARCHITECTURE.md §16 gives, so this package's version moves with the rest and its constraints on its siblings move with it.

0.2.0

• A pool, emitters, modifiers and a contributor that draws every live particle in one instanced call, on any backend the engine has.
• A particle can be a light source and can carry a texture.
