Classes aren't objects so you can't "show" them. If you are talking about local npcs (a npc made with putnpc2) then you should say local npc. Classes are just blocks of text that you append to scripts.

If you are talking about a local npc, I don't understand. Why would the npc not show to everyone?

EDIT:
Oh, on the serverside just do like:
this.attr[1] = thezoomyouwant;

Then on clientside you can do
setZoomEffect(this.attr[1]);
