my first code

[Liberated]

I hope this is the right place to post this, but i'm getting into Gscript2, and want to make sure i do everything correct, i was just wondering if i scripted this correctly, and what i could different and/or better.

PHP Code:

function onCreated () 
{
setimg ("door.png");
}

//#CLIENTSIDE

function onPlayerchats () 
{
 if (player.chat == "hello")
 {
 this.chat = "hi There";
 }
   else  
 if (player.chat == "you're dumb")
 {
  this.chat = "I do NOT wish to talk to you sir.";
 }
} 


yeah i know it's a talking door.
