Struct b2ParticleDef 

#[repr(C)]
pub struct b2ParticleDef {
    pub flags: uint32,
    pub position: b2Vec2,
    pub velocity: b2Vec2,
    pub color: b2ParticleColor,
    pub lifetime: f32,
    pub userData: *mut c_void,
    pub group: *mut b2ParticleGroup,
}

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

Fields

flags: uint32

\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: b2Vec2

The world position of the particle.

velocity: b2Vec2

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

color: b2ParticleColor

The color of the particle.

lifetime: f32

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

userData: *mut c_void

Use this to store application-specific body data.

group: *mut b2ParticleGroup

An existing particle group to which the particle will be added.
