traer attractions index
Jul 28th, 2009, 5:33pm  
Hi list!

In traer.physics lib have a method for remove particles and Attractions between 2 particles.

the Doc reference says:
Code:
int numberOfAttractions()
Attraction getAttraction( int index )
void removeAttraction( int index )
void removeAttraction( Attraction a )
Note removing things shifts the indices.


But i don't know that:  it's make an attraction index for each particle, or
an index for every 2 particles that share an attraction?

in other words:

Particle1/Particle2 -> 1 Attraction index?
or  
Particle1/Particle2 -> 2 Attraction index (one for each particle)?

Thanks

There is a method called numberOfAttractions() on ParticleSystem. Why not try create an attraction between two particles and ask ParticleSystem how many attractions there are.
