Add navigation to return to Scene 1 239

Link a button to a scene

Now that the playhead stops at Frame 1, you’ll add ActionScript that takes

the user to Scene 2 upon releasing the goScene_btn instance.

■ Press Enter (Windows) or Return (Macintosh) twice and type the

following comment. Then write the function that takes users to

Scene 2 upon release of the goScene_btn instance:

// This script takes the user to Scene 2 when goScene_btn

// is released.

goScene_btn.onRelease = function (){

gotoAndStop("Scene 2", 1);

};

In the script that you just typed, you used the onRelease() method

for the button object. The

gotoAndStop() function is a timeline

control function that lets you specify the scene and frame number. In

this case, you specified Frame 1.

Add navigation to return to

Scene 1

The function that you’ll add to the button in Scene 2, to return the user to

Scene 1, is similar to the function that you wrote to take the user to

Scene 2.

1. In the Scene panel, select Scene 2.

In the Timeline, create a new layer and name it Actions.

2. Select Frame 1 of the Actions layer.

In the Actions panel, enter the following in the Script pane:

// function takes user to Scene 1 when back_btn instance

// is released

back_btn.onRelease = function (){

gotoAndStop("Scene 1", 1);

};

The only differences between this function and the function in Scene 1

are the name of the button and the name of the scene.

3. In the Scene panel, select Scene 1.
