Detailed Description

Particle simulation / rendering.

Constructor & Destructor Documentation

gel::GelParticleSys::GelParticleSys ( )

Default constructor.

gel::GelParticleSys::GelParticleSys ( const char * desc_name )

Convenience constructor.

Reads a particle system description file from disk.

Parameters:

desc_name : The directory / name of a Gel2D Particle System description file.

gel::GelParticleSys::~GelParticleSys ( )

Destructor.

Member Function Documentation

Gel2dVec gel::GelParticleSys::getLoc ( ) const [inline]

Gets the location of particle emission.

Returns:: The location at which particles are emitted.

void gel::GelParticleSys::setLoc ( Gel2dVec loc ) [inline]

Sets the location of particle emission.

This is the location at which any subsequent particles will be emitted.
This is the way you will want to move particle systems, as opposed to using setPos(), which will translate the position of the entire system, existing particles and all. Not pretty.

Parameters:
