From d393bde2f559398ae6d0dcc8a436fe2a9c904e2c Mon Sep 17 00:00:00 2001 From: Jack Doyle Date: Fri, 5 Jun 2020 17:19:49 -0500 Subject: [PATCH] 3.3.1 - NEW: ScrollTrigger.batch() method that eliminates the need for something like IntersectionObserver in cases where you want to stagger the animations of elements as they enter the viewport. - NEW: ScrollTrigger now recognizes an onRefreshInit callback which can be useful in advanced situations where you want to reset positioning of elements just for the calculation of the start/end. If you return a gsap.set() call (or any GSAP animation, but it really only makes sense to do a gsap.set()), it'll actaully revert it automatically when the refresh finishes! - NEW: Any "refreshInit" listener can [optionally] return a gsap.set() call that'll get reverted as soon as the refresh finishes. Super useful for resetting positions just for the refresh() measurements. - IMPROVED: ScrollTrigger is now compatible with Internet Explorer and it no longer relies on the "name" being implicity defined. This also fixes some problems that occured in bundlers. See https://github.com/greensock/GSAP/issues/385#issuecomment-638798574 - FIXED: if you refresh a page after scrolling down, ScrollTrigger may call the onEnter for everything ABOVE that position (including triggers that are off-screen). Now it only fires the onEnter for triggers that are truly inbetween their start and end positions. - FIXED: here were a few TypeScript definition file problems. See https://github.com/greensock/GSAP/issues/383 and https://github.com/greensock/GSAP/pull/338 - FIXED: Various problems with ScrollTrigger not updating or refreshing properly in certain edge cases. - FIXED: in some rare cases, an error could be thrown by Draggable or MotionPathPlugin if you tried animating/dragging an element with an ancestor element that has been interacted with by GSAP but NOT related to transforms. See https://greensock.com/forums/topic/24318-nuxtjs-draggable-error-cacherendertransform-is-not-a-function/ - FIXED: if a nested tween gets overwritten INSIDE a stagger tween, it now adjusts the duration of that parent tween when appropriate. For example, if the last staggered tween gets killed, it should shorten the duration of the parent tween. --- README.md | 2 +- dist/CSSRulePlugin.js | 4 +- dist/CSSRulePlugin.min.js | 4 +- dist/CSSRulePlugin.min.js.map | 2 +- dist/Draggable.js | 4 +- dist/Draggable.min.js | 4 +- dist/Draggable.min.js.map | 2 +- dist/EasePack.js | 4 +- dist/EasePack.min.js | 4 +- dist/EasePack.min.js.map | 2 +- dist/EaselPlugin.js | 4 +- dist/EaselPlugin.min.js | 4 +- dist/EaselPlugin.min.js.map | 2 +- dist/MotionPathPlugin.js | 6 +- dist/MotionPathPlugin.min.js | 4 +- dist/MotionPathPlugin.min.js.map | 2 +- dist/PixiPlugin.js | 4 +- dist/PixiPlugin.min.js | 4 +- dist/PixiPlugin.min.js.map | 2 +- dist/ScrollToPlugin.js | 4 +- dist/ScrollToPlugin.min.js | 4 +- dist/ScrollToPlugin.min.js.map | 2 +- dist/ScrollTrigger.js | 220 +++++++++++++++++++----------- dist/ScrollTrigger.min.js | 4 +- dist/ScrollTrigger.min.js.map | 2 +- dist/TextPlugin.js | 4 +- dist/TextPlugin.min.js | 4 +- dist/TextPlugin.min.js.map | 2 +- dist/gsap.js | 6 +- dist/gsap.min.js | 4 +- dist/gsap.min.js.map | 2 +- esm/CSSPlugin.js | 2 +- esm/CSSRulePlugin.js | 4 +- esm/Draggable.js | 4 +- esm/EasePack.js | 4 +- esm/EaselPlugin.js | 4 +- esm/MotionPathPlugin.js | 4 +- esm/PixiPlugin.js | 4 +- esm/ScrollToPlugin.js | 4 +- esm/ScrollTrigger.js | 223 ++++++++++++++++++++----------- esm/TextPlugin.js | 4 +- esm/gsap-core.js | 7 +- esm/utils/matrix.js | 4 +- esm/utils/paths.js | 2 +- esm/utils/strings.js | 2 +- package.json | 2 +- src/CSSPlugin.js | 2 +- src/CSSRulePlugin.js | 4 +- src/Draggable.js | 4 +- src/EasePack.js | 4 +- src/EaselPlugin.js | 4 +- src/MotionPathPlugin.js | 4 +- src/PixiPlugin.js | 4 +- src/ScrollToPlugin.js | 4 +- src/ScrollTrigger.js | 154 +++++++++++++-------- src/TextPlugin.js | 4 +- src/gsap-core.js | 6 +- src/utils/matrix.js | 4 +- src/utils/paths.js | 2 +- src/utils/strings.js | 2 +- types/animation.d.ts | 14 +- types/gs-dev-tools.d.ts | 4 +- types/gsap-core.d.ts | 9 +- types/gsap-utils.d.ts | 4 +- types/motion-path-plugin.d.ts | 2 +- types/scroll-trigger.d.ts | 55 +++++++- types/timeline.d.ts | 4 +- 67 files changed, 558 insertions(+), 332 deletions(-) diff --git a/README.md b/README.md index 1544bfc5c..88a270c0b 100644 --- a/README.md +++ b/README.md @@ -18,7 +18,7 @@ View the full documentation here, inclu ### CDN ```html - + ``` Click the green "Get GSAP Now" button at greensock.com for more options and installation instructions, including CDN URLs for various plugins. diff --git a/dist/CSSRulePlugin.js b/dist/CSSRulePlugin.js index 6d5ee057c..6ca68ef5a 100644 --- a/dist/CSSRulePlugin.js +++ b/dist/CSSRulePlugin.js @@ -5,7 +5,7 @@ }(this, (function (exports) { 'use strict'; /*! - * CSSRulePlugin 3.3.0 + * CSSRulePlugin 3.3.1 * https://greensock.com * * @license Copyright 2008-2020, GreenSock.
