Method Summary

Modifier and Type	Method	Description
static Initializer	constant(pythagoras.f.Vector velocity)	Returns an initializer that provides a constant velocity.
static Initializer	increment(float dx, float dy)	Returns an initializer that increments the previously assigned velocity by the specified amounts.
static Initializer	randomCircle(Randoms rando, float maximum)	Returns an initializer that provides a velocity in a random direction with the specified maximum magnitude.
static Initializer	randomCircle(Randoms rando, float min, float max)	Returns an initializer that provides a velocity in a random direction with the specified minimum and maximum magnitude.
static Initializer	randomNormal(Randoms rando, float mean, float dev)	Returns an initializer that provides a normally distributed random velocity with the specified mean and standard deviation parameters.
static Initializer	randomNormal(Randoms rando, float xMean, float xDev, float yMean, float yDev)	Returns an initializer that provides a normally distributed random velocity with the specified mean and standard deviation parameters.
static Initializer	randomSquare(Randoms rando, float xRange, float yRange)	Returns an initializer that provides a uniformly distributed random velocity.
static Initializer	randomSquare(Randoms rando, float minX, float maxX, float minY, float maxY)	Returns an initializer that provides a uniformly distribted random velocity in the range minX to maxX and similarly for the y direction.

Method Details

constant

public static Initializer constant(pythagoras.f.Vector velocity)

Returns an initializer that provides a constant velocity.

randomSquare

randomNormal

public static Initializer randomNormal(Randoms rando,
 float mean,
 float dev)

Returns an initializer that provides a normally distributed random velocity with the specified mean and standard deviation parameters.

randomNormal

public static Initializer randomNormal(Randoms rando,
 float xMean,
 float xDev,
 float yMean,
 float yDev)
