Tween

Description

This class creates a basic tween, which automatically tracks a number from 0 to 1 over time. A Tweened number can be used within Processing to control an animation between two states. A Tween is given a time duration in seconds or frames, and optionally an easing function.

Example

import megamu.shapetween.*;

Tween ani;
void setup(){
  ani = new Tween(this, 2, Tween.SECONDS, Shaper.COSINE);
}

void draw(){
  background(255);
  ellipse(ani.time()*width, ani.position()*height, 4, 4);
}

Constructor

Tween( parent, duration )
Tween( parent, duration, durationType )
Tween( parent, duration, durationType, easing )

Parameters

parent

PApplet: typically use "this"

duration

float: tween duration in seconds unless you've set durationType to FRAMES

durationType

boolean: Tween.SECONDS or Tween.FRAMES (smoother)

easing

Shaper function used for animation easing. See setEasing() for details.
