1. ## MotionPathPlugin - 1D cubic path issue

Hi GSAP Team & Contributors, I've had hard times to make "1D cubic path" working. According to the following codepen, simply extracting the y property of a working curve data doesn't produce the same tween : let points = [{x:0,y:0},{x:50,y:0},{x:100,y:50},{x:100,y:100}]; // Reference Y let yValues= [{y:0} ,{y:0} ,{y:50} ,{y:100}]; // Not the same tween/smoothing GreenBall is 2D cubic path, as BlueRect is 1D cubic path using the same values https://codepen.io/swingingTom/pen/qBPBQQP A workaround a could have imagine is to tween another fake property in order to have a two-dimensional properties let points = [{x:0,y:0} ,{x:50,y:0} ,{x:100,y:50} ,{x:100,y:100}]; // Reference Y let yValues= [{y:0,foo:0},{y:0,foo:50},{y:50,foo:100},{y:100,foo:100}]; // Not the same tween/smoothing But according to this codepen, it won't work : https://codepen.io/swingingTom/pen/NWaWOXX I start to believe that `type:cubic` require both `x` and `y` property to produce the cubic smoothing. For now, my only working workaround is to animate a proxy target, that only reports "y" property on the real target to be animated. https://codepen.io/swingingTom/pen/GRMRYav gsap.to(proxyTarget, { duration: 3, ease: "none", repeat: -1, yoyo: true, motionPath: { path: cubicPoints2D, type: "cubic" }, onUpdate: function () { gsap.set(realDisplayTarget, { y: proxyY.y }); } }), I know that looks more like I should use CustomEase for the prodived cases, but I would like to know better the cubic motionpath features and its limitations.
