GS2: watch variable?

as in Javascript

example?:

PHP Code:


		
			
function onCreated()

  {

  this.var = 0;

  watch( this.name @ ".var" );

  this.var = 3; // echos: this.var changed from 0 to 3

  }



function onVarChanged( strName, oldVar, newVar )

  {

  echo( strName SPC "changed from" SPC oldVar SPC "to" SPC newVar );

  }

Usage:

PHP Code:


		
			
function onCreated()

  {

  watch( "clientr.health" );

  }



function onVarChanged( strName, oldVar, newVar )

  {

  if ( strName == "clientr.health" )

    {

    Health_Bar.width = newVar;

    // Effects, such as (newVar - oldVar) popping over the head to indicate damage

    }

  }

Outcome: Reduces Lag ( due to not requiring timeout's to check the change )

More Event-Driven systems

Not sure, but I would prefer a more generic "events" system.

PHP Code:


		
			
function onCreated() {

  event(player, "UpdateHealth").connect(this);

}



function onUpdateHealth(newVal) {

  Health_Bar.width = newVal;

}
