Particle Emitters, in general, are good in order to create an atmosphere in the games. The most common case is probably for smoke or fire and explosions. Particles can, however, be used for many interesting things. In this recipe, we're going to explore that by tuning a ParticleEmitter to create birds sailing through the sky.
The particles are still sprites, 2D images, so they will work best either far up in the sky, or below us.
The recipe will be divided into two parts. The first one contains setting up the
ParticleEmitter class in the SDK and writing the
ParticleInfluencer interface. The second part includes changing the way the
ParticleEmitter class behaves and extending our
ParticleInfluencer interface ...
