Chapter 3 38

5 When you get a shared object, make sure you connect it to the NetConnection object.

// Connect to the shared object

ball_so.connect(client_nc);

Create the function that updates the shared object data with the position of the ball.

// Manipulate the ball

SharedBall_mc.onPress = function() {

this.onMouseMove = function() {

ball_so.data.x = this._x = _root._xmouse;

ball_so.data.y = this._y = _root._ymouse;

// Constrain the ball to the stage

if (SharedBall_mc._x>=Stage.width) {

SharedBall_mc._x = Stage.width - 50;

}

if (SharedBall_mc._x<=0) {

SharedBall_mc._x = 50;

}

if (SharedBall_mc._y>=Stage.height) {

SharedBall_mc._y = Stage.height - 50;

}

if (SharedBall_mc._y<=0) {

SharedBall_mc._y = 50;

}

};

When the user releases the ball, remove the hold on it.

// Release control of the ball

SharedBall_mc.onRelease = SharedBall_mc.onReleaseOutside=function () {

delete this.onMouseMove;

};

To test your sample application:

1 In the Flash MX authoring environment, after you have saved your work, publish it by

selecting File > Publish.

2 Open two instances of the SWF file in the application directory.

3 Move the ball in one instance to see the other immediately updated.

Sample 4: Hello Server

This sample is the first to use server-side ActionScript. In it, you write your client-side

ActionScript in Macromedia Flash MX. Then, you write a corresponding function in server-side

ActionScript that you store in a main.asc file. First, however, you begin with the user interface.

About the sample

The user opens the doc_hello.swf file, enters a name, and gets a message back from the server that

includes the user’s name.

Re-creating the sample

The doc_hello.fla file provides the ActionScript for sending information from the server to the

client.

See “Creating your working environment” on page 31 before you start to re-create the sample.
