public class continuous_transition

extends transition

This is a transition for people who want to have a transition which lasts until you specifically remove it. This object never calls the animatable's end_transition function, only start_transition and the transition_step function. This object doesn't use trajectory or a pacing function, it just converts the current time into a Float object and sends that to the animatable. This object requires a continuous_interval for its time interval so it is sure that you will not pass it an interval which expires.

Field Summary

protected int

_freq How often does the user want calls (in milliseconds).

Constructor Detail

continuous_transition

public continuous_transition(animatable a,
                             continuous_interval pi,
                             int freq)

Construct a permanent transition given an animatable object and a frequency of calls.

Parameters:

animatable - a the object to animate

continuous_interval - pi

int - freq the frequency of calls in milliseconds

Method Detail

frequency

public int frequency()

Retrieve the frequency of calls to this animatable object.

Returns:

int the frequency of calls in milliseconds

set_frequency

public void set_frequency(int f)

Set the frequency of calls to this animatable object.

Parameters:

int - f frequency of calls in milliseconds

finished

public boolean finished()

This object is never finished.

Returns:

boolean always return false

Overrides:

finished in class transition

start

public void start(event e,
                  java.lang.Object user_info)

Start a transition.

Parameters:

event - e the animation event that caused things to get going

Object - user_info the object passed to the animation agent when the animatable joined its focus set

Overrides:

start in class transition

step

public void step(event e,
                 java.lang.Object user_info,
                 long current_time)

Perform a step... this sends the transition_step message to the interactor.

Parameters:

event - e the animation event for this step

Object - user_info the object passed to the animation agent when the animatable joined its focus set

long - current_time the time it is "now" for this time step

Overrides:

step in class transition
