# Particle System > Creating and controlling particle effects in Phaser 4 -- ParticleEmitter creation and configuration, emitter ops (value formats), gravity wells, emission and death zones, flow vs burst modes, following game objects, and particle callbacks. **Key source paths:** `src/gameobjects/particles/` **Related skills:** ../sprites-and-images/SKILL.md, ../loading-assets/SKILL.md ## Quick Start ```js // In a Scene's create() method: // Basic continuous emitter (flow mode) const emitter = this.add.particles(400, 300, 'flares', { frame: 'red', speed: 200, lifespan: 2000, scale: { start: 1, end: 0 }, alpha: { start: 1, end: 0 }, gravityY: 150 }); // One-shot burst (explode mode) const burst = this.add.particles(400, 300, 'flares', { frame: 'blue', speed: { min: 100, max: 300 }, lifespan: 1000, scale: { start: 0.5, end: 0 }, emitting: false // don't auto-start }); burst.explode(20); // emit 20 particles at once ``` ## Core Concepts ### ParticleEmitter `ParticleEmitter` extends `GameObject` and is added directly to the display list. It is both a game object (positionable, scalable, maskable) and the emitter itself. There is no separate manager -- `this.add.particles()` returns a `ParticleEmitter` instance. **Factory signature:** ```js this.add.particles(x, y, texture, config); // x, y: world position (both optional, default 0) // texture: string key or Texture instance // config: ParticleEmitterConfig object (optiona...
