Ani Animation Library

I'm having trouble triggering a stored ani animation. My sketch is organised so there is a separate file/tab listening for keypresses. I've decided to this because I have a limited number of buttons for input that I want to assign to different sets of animation events.

Oh, it's so difficult to explain. Be kind!

Main

import de.looksgood.ani.*;
import de.looksgood.ani.easing.*;
void setup()
{
size (640, 480);
noStroke();
Ani.init(this);
}
void draw()
{
motion1.display();
}

Motion

int diameter = 0;
Ani diameterAni;
class Motion
{
int diameter = 0;
Ani diameterAni;
void display()
{
diameterAni = new Ani(this, 2, "diameter", 150, Ani.ELASTIC_IN);
smooth();
if(allclear == 1) {
diameterAni.start();
}
ellipse (320,240,diameter,diameter);
}
}

Controller

int allclear = 0'
void keyReleased()
{
if (key == 'a')
{
allclear = 1;
}
}

What I think is happening is you're recreating the animation every frame, so it never get's to go beyond start, because it's new every time. The creation of diameterAni needs to be outside your display(). Try this...

import de.looksgood.ani.*;
import de.looksgood.ani.easing.*;
Motion motion1;
void setup()
{
size (640, 480);
noStroke();
Ani.init(this);
motion1 = new Motion();
}
void draw()
{
motion1.display();
}
int diameter = 0;
Ani diameterAni;
class Motion
{
int diameter = 0;
Ani diameterAni;
public Motion() {
diameterAni = new Ani(this, 2, "diameter", 150, Ani.ELASTIC_IN);
}
void display()
{
smooth();
if (allclear == 1) {
diameterAni.start();
}
ellipse (320, 240, diameter, diameter);
}
}
int allclear = 0;
void keyReleased()
{
if (key == 'a')
{
allclear = 1;
}
}
