Member Data Documentation

uint32 b2ParticleDef::flags

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

float32 b2ParticleDef::lifetime

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