====== About the script ======
  * Purpose : This script will place the items in an infinite looping row, so the camera movement is as smooth as possible. The items won't overlap, you can click them.

====== How to use the script ======

[Please note: I made the script time ago, and maybe it don't work now as expected. If so tell me in the link abobe]

Instructions:
  * copy paste this script and set it at the position change event of a container (it will use all the items inside, so better a panel)
  * the items will need to be not pinned and detached from the grid.
  * Set the scrolling to free scroll.

It automatically adapts if a new item is added or removed. However you will need to scroll one loop to update.

Settings: change them as you want
  * maxsize: the maximum size the items will have
  * see: the number of items you will be able to see at once

====== Script code ======
<sxh javascript>
/*Config */
var see = 5;// items you will see
var maxsize = 2; //Max scale of the item




var desk = LL.getEvent().getContainer();
var v = desk.getHeight()/2;
var h = desk.getWidth()/2;
var pos = desk.getPositionX();
if(h==0)return;
var items = desk.getItems();

var n = items.getLength()

var distance = 2*h/see;

for(var i=0;i<n;++i){
var p = Math.floor(pos/distance-n/2 +1);
var arg = (p+i)%n;
while(arg<0)arg+=n;
var item;
try{
item = items.getAt(arg);
}catch(e){alert("Error: arg="+arg+" p="+p+" pos="+pos+" distance="+distance+" h="+h);return;}
var size = pos-(p+i)*distance ;
if(size<0)size=-size;
size=maxsize-( size /h*maxsize );
if(size<0.1){
size =0.1;
}


item.setSize(distance/maxsize,2*v);

item.setScale(size,size);



item.setPosition( h+(p+i) *distance -distance/maxsize/2*size ,v-v*size);



/*items.getAt(arg).setLabel(items.getAt(arg).getWidth() ); */

}
</sxh>
