Detailed Description

Evolve particles in the gravitation field computed by the GravityEngine.

This script is attached to a Unity ParticleSystem.

Initialization of the particles may be handled by a script implementing IGravityParticleInit attached to the same game object that holds this component. Two common example are DustBall and DustRing. If there is no init delegate the Unity particle creation will be applied.

Each instance of GravityParticles manages the gravitational evolution of it's particle system. Particles are massless (they do not affect other particles) and are evolved with a built-in Leapfrog integrator. Particles which move within the particle capture radius of an NBody are made inactive and will not be further evolved. Particles that move outside the GravityEngine horizon are also made inactive.

Member Function Documentation

Evolve()

double GravityEngine2.GSParticles.Evolve	(	double	evolveTime,
		List< int >	massiveIndices,
		ref GEPhysicsCore::GEPhysicsJob	geJob )

Direct evolution of particles without using the Job system. To maintain common code this is done by calling a method on the particle job, but we are not scheduling a job (yet).

Parameters

evolveTime
massiveIndices
bodies

Returns

UpdateParticles()

void GravityEngine2.GSParticles.UpdateParticles	(	GSDisplay	gsDisplay,
		double	lenPhysToWorld )

Updates the particles positions in world space.

UpdateParticles is called from GSDisplay. Do not call from other scripts.

Parameters

physicalScale

Physical scale.
