java.lang.Cloneable

public class DefinedValuesAff

extends Affector

An artificial Affector which brings a Node from its initial value to a second value starting at a specified time and taking a specified amount of time to do the change. Then it holds it at the second value for another specified period of time. Finally, it drops it to a final value over yet another specified period of time. You might use this for a transient pre-pattern, for instance. Note that by setting some of the times to 0, you can simplify the pattern produced.

AN ADDITIONAL COMPLICATION: In order that this affector can be used in a spatially patterned way, the affector pays attention to the initial values in each cell. If the initial value is 0, then the affector always returns 0. If the initial value is 0.00001 or less, the value that this affector is trying to reach is multiplied by / 0.00001. If the init value is > 0.00001, there is no special behavior.

Formula
dnodex/dt = 0 | before first_time
dnodex/dt = (second_value - initial_value) / (second_time - first_time) | between first and second times
dnodex/dt = 0 | between second and third times
dnodex/dt = (third_value - second_value) / (fourth_time - third_time) | between third and fourth times
dnodex/dt = 0 | after fourth_time

Parameters

Target [nodex]	The Node which this Affector is acting on
First time [first_t]	See formula above
Second time [second_t]	See formula above
Third time [third_t]	See formula above
Fourth time [fourth_t]	See formula above
Second value [second_v]	See formula above
Third value [third_v]	See formula above

Usage
