Server-side ActionScript Notes

/ Published in: ActionScript

These are the standard event handlers for a new Application using the FMS.

Highlighted TextExpand

/*
Between the time an instance is created and destroyed, a number of things can happen. To simplify how things work, they are divided into three sections: startup, midlife, and shutdown.

Each application object is a singleton object. Each instance gets it's own application object which is an instance of the Application class.

These are all the standard event handler method of the application object

Below are methods that any client can call. You are also able to write such methods within onConnect like:
	
	///////////////////////////////////////////////////
	application.onConnect = function(p_client){
		p_client.changeText = function(p_client){
			//Do Something
		}
	}
	///////////////////////////////////////////////////

The reason you may not want to do this is because every time a user connects, this function will be placed into memory. Therefore if many users connect, you could begin to fing issues with memory allocation so it's much more efficient to use the psuedo Javascript Class called prototype.
