All of what exactly can this be used for, I had assumed for things like notices based on the time of the server.

But I wasn't really sure...was I right?

Example of use:

Putting it into a 'onDamage' clause in the player so that guild members can see other guild members health...

:O, awesome. I'll definitely be using it. Thanks Novo.

This seems like something nice, I will probably end up using it. Novo-can you please leave an explanation of what your code is, and what it does when you post? Thanks.

I thought I did! It is a broadcast system. Basically, you have Observers... And Events. Observers check to see if an event happened. They are interested when something happens. They may be anyone -- Jews, Russians, and even Christians at times. When the object does something, they signal a broadcast using 'postNotification( event )'. This sends an event to all the objects interested in THAT event. This allows them to do coordinate their efforts.

NPC1:

PHP Code:


		
			
function onCreated()

  {

  join("libnotice");

  scheduleevent(5, "Incoming", null);

  }



function onIncoming()

  {

  echo("Got it!");

  postNotification("got it");

  }

NPC2:

PHP Code:


		
			
function onCreated()

  {

  NPC1.addObserver( this, "GotIt", "got it" );

  }



function onGotIt()

  {

  echo("Do you get it too?");

  }

Of course -- Try not to make an event post an event that makes the initial event be posted... Such as adding this line to NPC1:

PHP Code:


		
			
this.addObserver( this, "Incoming", "got it" );

That smells sarcasm so badly. :( Let me go in my room and write a suicide note.
