This video discusses the default interpolation in GIF Loop Coder, and four distinct ways to change that interpolation to add variety to your animations.

 

Set Mode:

glc.setMode('single');//orglc.setMode('bounce');

 

Set Easing: 

glc.setEasing(false); //true

 

speedMult: Speed up the animation by number

phase: Delay the start animation by number

function onGLC(glc) {    glc.loop();//     glc.size(400, 400);//     glc.setDuration(5);//     glc.setFPS(20);//     glc.setMode('single');//     glc.setEasing(false);    var list = glc.renderList,        width = glc.w,        height = glc.h,        color = glc.color;    // your code goes here:        list.addCircle({        x: [50, 350],        y: height * 0.25,        radius: 20,        speedMult: 2,  // speed up        phase: 2, // delay starting    })        list.addCircle({        x: [50, 350],        y: height * 0.5,        radius: 20,        phase: 0.666    })            list.addCircle({        x: [50, 350],        y: height * 0.75,        radius: 20    })}
