Detailed Description

Component attached to slow/arcing projectile entities (rockets, slow bolts).

Records a ring-buffer of historical positions; the particle system expands consecutive node pairs into camera-facing ribbon quads each frame.

Member Data Documentation

count

int RibbonEmitter::count = 0

Number of live nodes.

head
