SetWiggle()

override void ParticleSource::SetWiggle ( float random_angle, float random_interval )

inlineprotected

Makes the particle change direction by random_angle every random_interval seconds.

Заметки

This does not actually work on Particle with no parent, it should on ParticleSource

Аргументы

random_angle	float Will be the range [-random_angle, random_angle[ to wiggle between
random_interval	float Will be the time range [0, random_interval] to wiggle next time
