Description
Implement a particle system for visual effects: tower attacks, creep deaths, explosions, ambient effects. CPU-driven particles rendered as instanced textured quads with billboarding. No particle or VFX infrastructure currently exists, but instancing infrastructure is available. Needs Particle and ParticleEmitter components, a ParticleSystem (FrameSystem), additive/alpha blended material, and a particle pool to avoid allocation spikes.
Steps
- Design
Particle (position, velocity, lifetime, scale, color) and ParticleEmitter (spawn rate, velocity distribution, texture) components
- Implement
ParticleSystem (FrameSystem): update positions, age particles, remove dead, pre-allocate pool
- Create
ParticleMaterial with additive blending and billboard quad shader
- Integrate with game events: tower fires projectile, creep dies, tower built
- Source or create 2-3 particle textures (spark, smoke, glow)
