void influenceParticle(Particle particle, EmitterShape emitterShape)
particle
- particle to be influencedemitterShape
- the shape of it emitterParticleInfluencer clone()
void setInitialVelocity(Vector3f initialVelocity)
initialVelocity
- Set the initial velocity a particle is spawned with,
the initial velocity given in the parameter will be varied according
to the velocity variation set in ParticleEmitter.setVelocityVariation(float)
.
A particle will move toward its velocity unless it is effected by the
gravity.Vector3f getInitialVelocity()
void setVelocityVariation(float variation)
variation
- Set the variation by which the initial velocity
of the particle is determined. variation
should be a value
from 0 to 1, where 0 means particles are to spawn with exactly
the velocity given in ParticleEmitter.setInitialVelocity(com.jme3.math.Vector3f)
,
and 1 means particles are to spawn with a completely random velocity.float getVelocityVariation()
