}

One emitter of a system.

Fields

name: Option<String>

The source’s name for it, if it has one.

parent: Option<u32>

The emitter this one hangs from; always an earlier one. None hangs it from the system’s frame.

placement: Transform

Placement in the parent’s frame (metres), in the world’s frame.

jitter_translation: [f32; 3]

Random placement jitter: translation by up to this much either way (metres), rotation about each axis (degrees).

jitter_rotation: [f32; 3]

attachment: Attachment

How the emitter follows its parent.

delay: f32

Seconds before it becomes active, and for how long (None for ever).

duration: Option<f32>

motion: Option<NodeMotion>

How it moves in its parent’s frame over its active time.

spawn: Spawn

shape: Shape

heading: Heading

spread: Spread

law: Law

draw: Option<Draw>

What it draws; None for an emitter that only holds children (or an effect-spawning one).

spawns: Vec<Entity>

Other effects this emitter starts when it becomes active (a source’s references to other effects): the entity of the system to start, attached to this emitter’s frame.

states: Vec<u32>

Which states of the system it exists in; empty for all of them.

order: f32

Display order among the system’s draws (lower draws in front, as a source’s depth bias states).

lod_range: Option<[f32; 2]>

The camera distances (metres, from and to) within which the emitter and its children exist; None for any distance (a source’s level-of-detail nodes give each child a range).

copies: Option<Pick>

For an emitter that makes copies of its children rather than particles: which children each emission starts. Its spawn schedules the emissions; each copy runs its children from its own start.
