A .yparticle: everything but its id (its path).

Fields

textures: Vec<String>

Its pictures, in order: the mod’s textures of the particles’ atlas (@texture:mymod:particle/cloud).

frames: Frames

Which of them it shows.

frame_speed: f32

How much faster than its life its frames go by age (Frames::Age).

frame_settle: bool

Once that faster run is past its life, its frames go by its age as it is (else they stay on the last).

lifetime: Lifetime

Ticks it lives: between min and max.

size: f32

Its size, times the game’s particles’ (which varies a little).

size_per_tick: f32

Its size times this each tick (1: it keeps it).

alpha: f32

Its opacity at first (0–1).

fade: bool

It fades out over its life, from alpha to none.

friction: f32

Its speed kept each tick.

gravity: f32

Blocks a tick² it falls (negative: rises).

gravity_needs_motion: bool

It falls (gravity) only when spawned moving along every axis.

physics: bool

It meets blocks (it doesn’t go through them).

slide_when_blocked: bool

It speeds up sideways when something stops it rising or falling.

random_roll: bool

It starts turned at random (else upright).

render: ParticleRender

How it’s drawn.

Trait Implementations

impl Clone for Particle

fn clone(&self) -> Particle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Particle

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Fields for Particle

const FIELDS: &'static [(&'static str, &'static str)]

impl PartialEq for Particle

fn eq(&self, other: &Particle) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Schema for Particle

fn encode(&self, __yog_w: &mut Writer)

Writes itself in the binary form, straight — Schema::write’s value encoded, unless the type knows better (derived ones do).

fn pack(&self, __yog_p: &mut Packer)

Packs itself into a frame (crate::frame): its binary form as bytes, unless the type packs itself (derived ones and plain types do).

fn unpack(__yog_u: &mut Unpacker<'_>) -> Option<Particle>

Reads itself out of a frame; None if the bytes aren’t what Schema::pack writes.

fn shape() -> Shape

What the format looks like.

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<Particle>

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

fn write(&self) -> Value

The value, as the format writes it.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.

fn decode(d: &mut Decoder<'_>) -> Option<Self>

Reads itself from the binary form, straight; None when it isn’t what Schema::encode writes — then read_bytes reads the slow way, which says what’s wrong. Through a value unless the type knows better (derived ones do).

fn pack_list(items: &[Self], p: &mut Packer)

A list of these packed: a count, then each one (floats raw).

fn unpack_list(u: &mut Unpacker<'_>) -> Option<Vec<Self>>

A list of these out of a frame.

fn encode_list(items: &[Self], w: &mut Writer)

A list of these written straight (numbers pack theirs).

fn decode_list(d: &mut Decoder<'_>) -> Option<Vec<Self>>

A list of these read straight.
