Module: ParticleFX2D::Ruby2D::ShapeRenderer

Includes:
ParticleFX2D::Renderer
Included in:
ParticleCircle, ParticleImage
Defined in:
lib/particlefx2d/ruby2d/shape_renderer.rb

Overview

The base definition for a Ruby2D shape-based renderer that can be peered to a particle managed by the ParticleFX2D Emitter. Include this when defining Ruby2D shape-specific classes to provide the Emitter to render the particle.

This approach requires a shape per particle.
