A particle definition holds all the data needed to construct a particle. You can safely re-use these definitions.

Fields

flags: ParticleFlags

\brief Specifies the type of particle (see #b2ParticleFlag).

A particle may be more than one type. Multiple types are chained by logical sums, for example: pd.flags = b2_elasticParticle | b2_viscousParticle

position: Vec2

The world position of the particle.

velocity: Vec2

The linear velocity of the particle in world co-ordinates.

color: ParticleColor

The color of the particle.

lifetime: Float32

Lifetime of the particle in seconds. A value <= 0.0f indicates a particle with infinite lifetime.

user_data: size_t

Use this to store application-specific body data.

group: Option<ParticleGroup>

Trait Implementations

impl Default for ParticleDef

fn default() -> ParticleDef

Returns the "default value" for a type.
