Chapter 452

For example, the code below shows how you could create a network connection on the client side,

and then make a call to it from the server side:

// This is client-side ActionScript in the FLA

my_nc = new NetConnection();

my_nc.someClientMethod = function()

{

// code here

}

// This is server-side ActionScript in the main.asc file

clientObj.call("someClientMethod");

The argument passed to clientObj.call must be a previously defined method of the client-side

NetConnection object. This is because any method in the client code that may be called by the

server must be a property of a client-side NetConnection object.

In contrast, suppose you use the

call method from the client, to call a method on the server side:

// This is client-side ActionScript in the FLA

NetConnection.call("someServerMethod");

// This is server-side ActionScript in the main.asc file

client.prototype.someServerMethod = function()

{

// code here

}

// The following code would also work

onConnect(newClient)

{

newClient.someServerMethod = function()

{

// code

}

In this case, the argument passed to NetConnection.call must be a method of the server-side

Client object that was previously defined in the main.asc file. This is because any method in the

server code that may be called by the client must be a property of a server-side Client object.

Using multiple files

As your application increases in complexity, don’t try to use a single script to do everything: break

your functionality up into multiple scripts, each of which provides a specific set of functionality.

If you do use more than one file, you can optimize performance by using a “once-only inclusion”

definition to prevent a file from being evaluated more than once.

On the client side

For example, on the client side, if you want a file named my_file.as to be available to other files in

your application, include the following code in my_file.as:

if (_root._my_file_as == null) {

_root._my_file_as = true;

// All the code for myfile.as goes here

}

Then, in your other files, issue the following command:

#include "my_file.as";
