Beginner Scripting is GS2

[maximus_asinus]

Okay I have loads of questions but I'll try reading all of the Graal Bible thoroughly before I unload them all on you guys/gals.

First off, I am busy converting many of the predefined objects I use. I 'converted' Stefan's light NPC, basically searching for the functions in Graal Bible and pasting them in, but I'm not sure if I have it correct, nor do I think it is as efficient as it could be.

function onCreated() {
  setimg(light2.png);
  dontblock();
}
//#CLIENTSIDE
function onPlayerEnters() {
  drawaslight();
  setcoloreffect(1, 1, 1, .99);
  setzoomeffect(3);
}

I'll be back with more questions!

EDIT: I meant "in GS2" and not "is GS2". Someone might read that and get insulted :3
EDIT: Is there a server open to a Classic subscriber where I could test my scripts for trial and error, rather than me asking each question?
EDIT: What is the difference between onCreated and onPlayerEnters? Does the NPC server process an NPC that uses onCreated immediately, without the player being in the level? If I used onCreated clientside would it be treated differently, more like onPlayerEnters?
