| float32 b2ParticleSystemDef::colorMixingStrength |
Determines how fast colors are mixed 1.0f ==> mixed immediately 0.5f ==> mixed half way each simulation step (see b2World::Step())
| float32 b2ParticleSystemDef::dampingStrength |
Reduces velocity along the collision normal Smaller value reduces less
| float32 b2ParticleSystemDef::density |
Set the particle density. See SetDensity for details.
| bool b2ParticleSystemDef::destroyByAge |
| float32 b2ParticleSystemDef::ejectionStrength |
Pushes particles out of solid particle group Larger values repulse more
| float32 b2ParticleSystemDef::elasticStrength |
Restores shape of elastic particle groups Larger values increase elastic particle velocity
| float32 b2ParticleSystemDef::gravityScale |
Change the particle gravity scale. Adjusts the effect of the global gravity vector on particles. Default value is 1.0f.
| float32 b2ParticleSystemDef::lifetimeGranularity |
Granularity of particle lifetimes in seconds. By default this is set to (1.0f / 60.0f) seconds. b2ParticleSystem uses a 32-bit signed value to track particle lifetimes so the maximum lifetime of a particle is (2^32 - 1) / (1.0f / lifetimeGranularity) seconds. With the value set to 1/60 the maximum lifetime or age of a particle is 2.27 years.
| int32 b2ParticleSystemDef::maxCount |
Set the maximum number of particles. By default, there is no maximum. The particle buffers can continue to grow while b2World's block allocator still has memory. See SetMaxParticleCount for details.
| float32 b2ParticleSystemDef::powderStrength |
Produces repulsion between powder particles Larger values repulse more
| float32 b2ParticleSystemDef::pressureStrength |
Increases pressure in response to compression Smaller values allow more compression
| float32 b2ParticleSystemDef::repulsiveStrength |
Produces additional pressure on repulsive particles Larger values repulse more Negative values mean attraction. The range where particles behave stably is about -0.2 to 2.0.
| float32 b2ParticleSystemDef::springStrength |
Restores length of spring particle groups Larger values increase spring particle velocity
| int32 b2ParticleSystemDef::staticPressureIterations |
Computes static pressure more precisely See SetStaticPressureIterations for details
| float32 b2ParticleSystemDef::staticPressureRelaxation |
Reduces instability in static pressure calculation Larger values make stabilize static pressure with fewer iterations
| float32 b2ParticleSystemDef::staticPressureStrength |
| bool b2ParticleSystemDef::strictContactCheck |
Enable strict Particle/Body contact check. See SetStrictContactCheck for details.
| float32 b2ParticleSystemDef::surfaceTensionNormalStrength |
Smoothes outline of tensile particles 0~0.2. Larger values result in rounder, smoother, water-drop-like clusters of particles.
| float32 b2ParticleSystemDef::surfaceTensionPressureStrength |
Produces pressure on tensile particles 0~0.2. Larger values increase the amount of surface tension.
| float32 b2ParticleSystemDef::viscousStrength |
Reduces relative velocity of viscous particles Larger values slow down viscous particles more
