Particle Candy emitter running the attractor sample
Note
Chapter 14 will discuss a related tool, Particle Designer, which can be used to visually create
particle effects and export the settings to Particle Candy.
Sample Code
Particles.CreateEmitter("E1", screenW*0.05, screenH*0.5, 45, true, true)
-- DEFINE A PARTICLE TYPE
