Detailed Description

Implementation of spark burst and impact flash effect.

Function Documentation

randf()

float randf ( )

static

Return a random float in [0, 1].

spawnBloodBurst()

void spawnBloodBurst ( ParticlePool< BillboardParticle, 4096 > & pool, glm::vec3 pos, glm::vec3 normal, float frameDt )

static

Spawn a juicy blood burst for flesh impacts.

Three layers: 1) Fast splatter streaks — bright red, high speed, elongated by velocity. 2) Slow blood mist — large, dark, lingering cloud. 3) Heavy droplets — medium speed, strong gravity, drip downward.
