====== About the script ====== * Purpose : These scripts will give you a beautiful page transition animation and an optional horizontal page loop * Author : [[https://plus.google.com/+LukasMorawietz|LM13]] * Current Version : 2.1 * Link: https://plus.google.com/115366157037831519359/posts/eUtogDspL2X * Download avialable! (Check repository) ====== Changelog ====== * Version 1.0 (5/7/2014): initial release in wiki * Version 2.1 (12/7/2014): no second script needed anymore, added optional fade, improved speed for lot of pages & items ====== How to use the script ====== * Set the script to the positionchanged event of your container; configure the main script, if you want fading * enable infinte scrolling if you want a page loop, disable it if you don't want to loop through pages * in this container: create a shortcut or a gesture to the script * one click on the shortcut will enable the animation, clicking again will disable the animation. * BE SURE TO DISABLE THE ANIMATION BEFORE YOU EDIT, MOVE OR ADD ITEMS!
