A component library to try enhance the particle system a bit
ParticleForce.cs
A particle controller that applies a per-particle directional force each simulation step. It reads X/Y/Z force components and a force scale from ParticleFloat properties, optionally converts the force into local space, then modifies the particle velocity each step.
