====== About the script ======
  * Purpose : These scripts will give you a beautiful page transition animation and a horizontal page loop
  * Author : Lukas Morawietz alias LM13
  * Current Version : 1.0
  * Link : https://plus.google.com/115366157037831519359/posts/GXVcfSaWVRi

====== Changelog ====== 
  * Version 1.0 (1/4/2014): initial release in wiki

====== How to use the script ======
  * Set the main script to the positionchanged event of you container
  * enable infinte scrolling
  * in this container: create a shortcut to the toggle script and set up toggle sripts configuration
  * 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!

====== Issues and hints ====== 
  * this will break any other script, which uses item or container tags, and will be broken by them   
  * at some point it may flicker 
  * with many items it won't run smooth
  * don't use dual position, this will do weird stuff

//please report all bugs in the g+ community//

====== Main Script code ======
<code>var d=LL.getEvent().getContainer();
var cont=JSON.parse(d.getTag()||"null");
if(cont==null || !cont.setup)
{
return;
}
var dwidth=d.getWidth();
var pos=d.getPositionX();
var current=Math.floor(pos/dwidth);
var pagepos=current*dwidth;
var dposy=d.getPositionY();
var percent=(pos-pagepos)/dwidth;
var items=d.getItems();
var l=items. getLength();
var tag=parseInt(LL.getScriptTag());
var maxpage= Math.floor((cont.max-dwidth)/dwidth);


if((percent>0.005&&percent<99.995) && pos>cont.min-dwidth)
{
if(pos>cont.max-dwidth)
{
d.setPosition(cont.min-dwidth ,dposy,1,false);
}
if(pos<cont.min)
{
cont.state=2;
}
for(i=0;i<l;i++)
{
item=items.getAt(i);
var pinned= item.getProperties().getString("i.pinMode");
if(pinned=="NONE"|| pinned=="Y")
{
var data=JSON.parse(item.getTag());
if(data.page==current || (cont.state==2 && data.page==maxpage))
{
if(Math.abs(1-percent-item.getScaleX())>0)
{
item.setScale(1-percent,1);
item.setPosition(pos+data.posx*(1-percent),data.posy);
}
}
if(data.page==current+1)
{
if(Math.abs(percent-item.getScaleX())>0)
{
item.setScale(percent,1);
item.setPosition(pos+dwidth-(dwidth-data.posx)*percent,data.posy);
}
}
}
