Struct ParticleEmitter2 

pub struct ParticleEmitter2 { /* private fields */ }

Particle emitter version 2 (sprite-based)

More advanced particle system that uses sprite textures. Supports various particle shapes, blending modes, and animation over the particle lifetime. Used for fire, smoke, magic effects, etc.
