   alpha is a property, so you need to edit the properties of the item concerned.

   
   

   In general to edit properties you have to do it in this way:

   
   

   
   

   1st – you need to take in input the item by name or id

   
   

   
   

   2nd – edit the properties and then commit

   
   

      

   
   

         item(generic name).getProperties().edit()

   
   

         .setInteger(“some name(in this case i.alpha)”,some int value(int this case 0 – 255 or a var))

   
   

        .commit()

   Patryk Goworowski LOL! Follow this little explanation

   
   

   
   

   create a var linked with the x or y scroll:

   
   

   
   

   var desk = LL.getCurrentDesktop(); //or get a container in input

   
   

   var x = desk.getPositionX(); //or Y

   
   

   
   

   the assign it to a var:

   
   

   
   

   var a = x/some int value;

   
   

   
   

   conditions:

   
   

   
   

   if(a>255) a=255;

   
   

   if(a<0) a=0;

   
   

   
   

   put this var in properties editor and you will have alpha changing through scroll.

   Simone Boccuzzi​ Thanks, but I made the script work already. I just couldn’t figure out how to change item alpha with script. 😀

   Simone Boccuzzi Just a quick optimization for clipping conditions:

   
   

   var a=Math.min(Math.max([alphacalculation],0),255);
