Method Details
-
influenceParticle
This method influences the particle.- Parameters:
particle
- particle to be influencedemitterShape
- the shape of its emitter
-
clone
ParticleInfluencer clone()This method clones the influencer instance.- Returns:
- cloned instance
-
setInitialVelocity
- Parameters:
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 inParticleEmitter.setVelocityVariation(float)
. The particle will move with this velocity unless it is affected by gravity.
-
getInitialVelocity
Vector3f getInitialVelocity()This method returns the initial velocity.- Returns:
- the initial velocity
-
setVelocityVariation
void setVelocityVariation(float variation) - Parameters:
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 inParticleEmitter.setInitialVelocity(com.jme3.math.Vector3f)
, and 1 means particles are to spawn with a completely random velocity.
-
getVelocityVariation
float getVelocityVariation()This method returns the velocity variation.- Returns:
- the velocity variation
