	Provide the initial positions and velocity for a range of particles. This method will be called as particles are created by the particle system. The implementing class must fill in the r[,] and v[,] arrays for the range specified. These arrays are indexed by [particle_num, dimension] where dimension 0,1,2 correspond to x,y,z.

Detailed Description

Explosion from N body. Generates the particle positions/velocities for an "ejection cone" of debris when NBody objects collide.

This script is typically part of an explosion prefab object (with a GravityParticles component) that is then referenced by an NBodyCollision object. The NBodyCollision component will initialize via calling Init() and then the particles will be created according to the inspector parameters.

Member Function Documentation

InitNewParticles()

void ExplosionFromNBody.InitNewParticles	(	int	fromParticle,
		int	toParticle,
		ref double	r[,],
		ref double	v[,]
	)

Provide the initial positions and velocity for a range of particles. This method will be called as particles are created by the particle system. The implementing class must fill in the r[,] and v[,] arrays for the range specified. These arrays are indexed by [particle_num, dimension] where dimension 0,1,2 correspond to x,y,z.

See the DustBox script for a sample usage of this interface.

Parameters

fromParticle	From particle number.
toParticle	To particle number.
r	(out) 2D array [numParticles, 3] to hold physics position (x,y,z) per particle
v	(out) 2D array [numParticles, 3] to hold velocity (x,y,z) per particle

Implements IGravityParticlesInit.
