Hey all, I'm working on making a seisomgraph animation, I have the needle animating with random data every second so far. But I'm not sure how to approach the line drawing animation part. I am using GSAP to animate the needle, and was thinking I could read the x, y value at the end of the needle. Then.. save into an array and create a path, clear and draw for every needle animation update. Is this efficient? Is there a better/different way to do this? Thanks for the help!! this.needleGfx.lineStyle(4, 0xffff, 1); this.needleGfx.moveTo(this.xScale(this.maxTime), this.yScale(0)); this.needleGfx.lineTo(this.xScale(this.maxTime) - (this.yScale(0) - this.yScale(this.highValue)), this.yScale(0)); this.needleLen = this.yScale(0) - this.yScale(this.highValue); this.animateLineTest(); animateLineTest() { const x1 = 0; this.y1 = 0; this.y2 = 0; this.x2 = Math.sqrt(this.needleLen ** 2 - this.y2 ** 2); this.prevY2 = this.y2; this.updateTimer = setTimeout(this.updateNeedle.bind(this), 1000); } updateNeedle() { const timeline = gsap.timeline(); const newY2 = { y2: this.prevY2 }; timeline.to(newY2, { duration: 1, y2: this.y2, onUpdate: () => { this.needleGfx.clear(); this.x2 = Math.sqrt(this.needleLen ** 2 - (this.yScale(0) - this.yScale(newY2.y2)) ** 2); this.needleGfx.lineStyle(4, 0xffff, 1); this.needleGfx.moveTo(this.xScale(this.maxTime), this.yScale(this.y1)); this.needleGfx.lineTo(this.xScale(this.maxTime) - this.x2, this.yScale(newY2.y2)); }, onComplete: () => { function randomBetween(min, max) { if (min < 0) { return min + Math.random() * (Math.abs(min) + max); } else { return min + Math.random() * max; } } console.log("Animation completed."); this.prevY2 = this.y2; this.y2 = randomBetween(-10, 10); this.updateNeedle(); }, }); } seismograph-line.mp4

so my gsap duration is longer than next requestAnimationFrame(), lets say 2secs my ques: will it destroy my program in long run? should i bother about it and optimize it? will it create multiple gsap threads? how to optimize/destroy old gsap in next requestAnimationFrame?

Hello, First time posting on this forum. Issue: I am having issues using TweenMax when rendered in WebGL with PIXI. Nothing happens at all. If I change my code to use canvas it works just fine. Is anybody having similar or the same issues? Thanks for any help. let app = new PIXI.autoDetectRenderer(1920, 1080); document.body.appendChild(app.view); let stage = new PIXI.Container(); let testGraphic = new PIXI.Graphics(); testGraphic.beginFill(0x18FF10); testGraphic.drawRect(0, 0, 500, 500); stage.addChild(testGraphic); TweenMax.to(testGraphic, 1, {pixi: {alpha: 0}}); app.render(stage);

Hello! I'm find the perfect animation example but it works only on one image and in default mode (autoplay on page load). I need to init this only on mouseenter event and for each current image. This is example in codepen I'm found contidion to mouseenter and mouseleave event if ( options.interactionEvent === 'hover' || options.interactionEvent === 'both' ) { slidesContainer.pointerover = function( mouseData ){ mouseX = mouseData.data.global.x; mouseY = mouseData.data.global.y; TweenMax.to( displacementFilter.scale, 6, { x: "+=" + Math.sin( mouseX ) * 100 + "", y: "+=" + Math.cos( mouseY ) * 100 + "" }); rotateSpite(); }; slidesContainer.pointerout = function( mouseData ){ TweenMax.to( displacementFilter.scale, 1, { x: 0, y: 0 }); cancelAnimationFrame( rafID ); }; } The default animation settings is: if ( options.autoPlay === true ) { var ticker = new PIXI.ticker.Ticker(); ticker.autoStart = options.autoPlay; ticker.add(function( delta ) { displacementSprite.x += options.autoPlaySpeed[0] * delta; displacementSprite.y += options.autoPlaySpeed[1]; renderer.render( stage ); }); } I thought I can do something like this if ( options.interactionEvent === 'hover' || options.interactionEvent === 'both' ) { var ticker = new PIXI.ticker.Ticker(); ticker.autoStart = options.autoPlay; ticker.add(function( delta ) { displacementSprite.x += options.autoPlaySpeed[0] * delta; displacementSprite.y += options.autoPlaySpeed[1]; renderer.render( stage ); }); } This is pen with that "changed" part https://codepen.io/Frunky/pen/oMZbvr Also I need to load all items, but loads only one item. Why? Thanks

Hello. I tried to get a kind of focus helper with the mouse when the pointer rolls over an item. but i can get a good easing when the mouse are hover a element. I do not know if I explain myself well, but I will try. i use the pointerLock API. when the mouse icon get hover a new elements, i want to help the mouse to move to center of element. But without disturbing the control of the mouse. the idea is to create a focus helper to center the pointer on the elements when the mouse has a contact with the outlines. i try my best to make a codepen. for active the pointer lock, just click inside the blue square. https://codepen.io/djmisterjon/pen/gzJVRR/?editors=1011 if your move the mouse, your will see that the behavior is a little messy when the mouse flies over a white square. An idea on a good approach to create a similar system? Am using GSAP libs. thank a lot for help. my source code am trying patch look like this , but it very similar to the code pen demo. /*: // PLUGIN □────────────────────────────────□MOUSE INTERACTIVITY□───────────────────────────────┐ * @author □ Jonathan Lepage (dimisterjon),(jonforum) * @plugindesc MOUSE ENGINE * V.0.1a * License:© M.I.T └───────────────────────────────────────────────────────────────────────────────────────────────────┘ Controle tous ce qui est associer a la sourits, interaction avec player et camera engine Initialise avantr le loader , seulement pendant la sceneBOOT */ // ┌-----------------------------------------------------------------------------┐ // GLOBAL $mouse CLASS: _mouse //└------------------------------------------------------------------------------┘ function _mouse() { PIXI.Container.call(this);

Hello everyone! I'm using TweenMax.js (GSAP) to tween position for model with bezier but model's rotation incorrect. This is PG: http://www.babylonjs-playground.com/#H30ZQI How to fish's head rotation in the direction of movement? (JUST use TweenMax.js, DON'T use BABYLON.Path3D). Thanks you!

Hi, this is my first try with Pixi and I would love to animate it using my fav tweening library Greensock. ABove is my pen. I don't get any errors, yet my displacementMap isn't animating... What am I doing wrong here? Any other improvements are also welcome. Thank you so much!

Hello everyone, i am new here, and would like to ask my first question! I have made a 2d canvas game using mainly CreateJS, and GSAP. For various reasons, i would like to be use Firefox as a browser, but i have had some performance issues that couldn't surpass. So i decided to check a webgl based rendering library such as pixiJS. I have made a quick test page to see if i could get smooth tweening using webgl rendering vs canvas based rendering. I would expect better framerates using webgl, but the truth is that i get lower framerates and really jerky motion. All the articles and examples i've read about the past couple of days were saying the exact opposite. So what am i really missing? Is it Firefox's problem? Is it that i use GSAP for tweening? Is my example code missing anything essential? You could check my quick demo here : http://jsfiddle.net/thvphuub/3/ And i would suggest to run the two versions in fullscreen to see the FPS yourself using the two following links : Using canvas : https://jsfiddle.net/thvphuub/2/embedded/result/Using webgl : https://jsfiddle.net/thvphuub/3/embedded/result/ Actually the above runs quite smoothly using canvas on Firefox...:-S Any insight would be great.Thanks in advance!

Hello folks, I'm a newbie and I try to figure out how this framework works. After I watched this site, I was amazed and wanted to learn more. http://www.shanemielke.com/archives/usopen-sessions/ I'm a little bit stuck on a case. So what I want to do is to draw 3 line that match the border of my window. That's fine, but In a second step, I'd like that this lines move without leaving the border. Here is my little code for this part // This is how I create the line var lineArray = []; for (var i = 0; i < 3; i++) { var line = new PIXI.Graphics(); line.lineStyle(1, 0xf3a33f); if(i == 0) { line.moveTo(getRandomInt(0, window.innerWidth), window.innerHeight); line.lineTo(getRandomInt(0, window.innerWidth), 0); } else if(i == 1) { line.moveTo(0, getRandomInt(0, window.innerHeight)); line.lineTo(window.innerWidth, getRandomInt(0, window.innerHeight)); } else { line.moveTo(getRandomInt(0, window.innerWidth), window.innerHeight); line.lineTo(window.innerWidth, getRandomInt(0, window.innerHeight)); } line.endFill(); line.alpha = 0; stage.addChild(line); lineArray.push(line); }// And this is how I want to animate itvar timeline = new TimelineMax({ paused: true });for (var i = lineArray.length - 1; i >= 0; i--) { lineArray[i].beginFill(0xf3a33f, 1); timeline.add(TweenMax.to( lineArray[i], .05, {alpha: 1}), 1.25);}timeline.play();Is there anyway to do that with the timeline ? Cheers guys !
