An individual Particle, spawned by a ParticleSystem

The parent_entity should link to the entity with the spawning ParticleSystem on it.

If the parent_entity no longer exists or does not contain a ParticleSystem the particle will be despawned immediately.

The parent should be linked here explicitly because particles may operate in world space, and not be actual children of the ParticleSystem itself.

Fields

parent_system: Entity

The entity on which the spawning ParticleSystem resides.

max_lifetime: f32

The total lifetime of the particle.

When the Lifetime component value reaches this value, the particle is considered dead and will be despawned.

max_distance: Option<f32>

The maximum distance traveled for the particle.

When the DistanceTraveled component value reaches this value, the particle is considered dead and will be despawned.

use_scaled_time: bool

Whether the particle will respect scaled time in its transformations.

This is copied from ParticleSystem::use_scaled_time on spawn.

initial_scale: f32

The initial scale of the particle, multiplied with scale to produce the final scale of the particle.

scale: ValueOverTime

The scale or size of this particle over time.

This is copied from ParticleSystem::scale on spawn.

velocity_modifiers: Vec<VelocityModifier>

Velocity Modifiers of this particle.

This is copied from ParticleSystem::velocity_modifiers on spawn.

rotation_speed: f32

The speed, in radian per second, at which the particle rotates.

This is chosen from ParticleSystem::rotation_speed on spawn.

despawn_with_parent: bool

Indicates whether the particle should be cleaned up when the parent system is despawned
