I am creating a game using bevy 0.12 and bevy_hanabi and am creating the visual effects for a space-themed thruster. Ideally, I would be able to chuck something in a Query< ... >, and update some property/attribute/data to reduce the acceleration of newly spawned particles. This way, the strength of the thrusters can be visually seen.
In previous versions, to control the thruster particle effects I simply call mut q_spawner: Query<&mut EffectSpawner> ... q_spawner.single_mut().set_active( ... ) which worked just fine. I want more control than a simple binary 'active' or 'inactive' however.
(I'm currently looking into CompiledParticleEffect::set_property)
