Intro to Action Script 3

"The games of a people reveal a great deal about them.“ Marshall McLuhan


Random function – random_answer.fla

Review the random_answer.fla movie from the Pickup folder.



The text buttons is a Dynamic Text linked to a variable “fortune”



The invisible button contains all the scripts.

1. Array of the possible answers

on (release) {// make list of possible responsesresponses = new Array();responses.push("Yes");responses.push("No");responses.push("Ask again later");responses.push("It is certain");responses.push("Doubtful");responses.push("Probably");responses.push("The answer is unclear");responses.push("Of course not!");responses.push("Certainly!");responses.push("It looks positive");responses.push("It looks negative");

// get number of responsesn = responses.length;

// pick random responser = Int(Math.random()*n);

// place response in text areafortune = responses[r];

// start animationgotoAndPlay(2);

}



The array can also be a simple collection of variables:

on (release) {// make list of possible responses

responses = new Array("Yes", "No", "Ask again later", "It is certain",

"Doubtful", "Probably", "The answer is unclear",

"Of course not!", "Certainly!","It looks positive",

"It looks negative" );



// get number of responsesn = responses.length;

// pick random responser = Int(Math.random()*n);

// place response in text areafortune = responses[r];

// start animationgotoAndPlay(2);

}


Random function – jukebox.fla

Flash supports .aiff, .mp3, .wav, sound formats

Import sounds to the library



Linkage

Identifier: song1

Export for ActionScript



10 identical movie clips with dynamic text areas “song name” Named 1, 2, 3, 4, 5, 6, 7, 8, 9, 10



10 identical movie clips with dynamic text areas “song name”Button script inside movie clip

on (release) {_root.playSong(this._name);

}



10 identical movie clips with dynamic text areas “song name”Button script inside movie clip

on (release) {_root.playSong(this._name);

}

Takes the name of the movie clip – “1” to “10” –And sends it to a “playSong” function at the root level.

Used for each movie clip since the name is different each time

This._name gets different results from different instances of the same movie clip as long as they named differently



dynamic text areas “song name” linked to variable “text”stop action on the first frame



The text for each movie clip instance is changedEach instance displays a different song nameEven though we have one movie clip symbol in the library each

instance looks different on the stage

// set the song namesthis["1"].text = "Song Name 1";this["2"].text = "Song Name 2";this["3"].text = "Song Name 3";this["4"].text = "Song Name 4";this["5"].text = "Song Name 5";this["6"].text = "Song Name 6";this["7"].text = "Song Name 7";this["8"].text = "Song Name 8";this["9"].text = "Song Name 9";this["10"].text = "Song Name 10";stop();



// play new sound

song = new Sound(); creates a sound object

song.attachSound("song"+songnum); associates the sound in the library with this object

song.start(); plays sound



function playSong(songnum) {// stop the previous song, if anysong.stop();

// turn off all lightsfor(i=1;i<=10;i++) {

this[i].gotoAndStop(1);}

// play new soundsong = new Sound();song.attachSound("song"+songnum);song.start();

// turn light onthis[songnum].gotoAndStop(2);

}

// set the song namesthis["1"].text = "Song Name 1";this["2"].text = "Song Name 2";this["3"].text = "Song Name 3";this["4"].text = "Song Name 4";this["5"].text = "Song Name 5";this["6"].text = "Song Name 6";this["7"].text = "Song Name 7";this["8"].text = "Song Name 8";this["9"].text = "Song Name 9";this["10"].text = "Song Name 10";stop();


Exercise – dice

Create an interactive animation dice game with two dice and button “roll” to through them.

Each dice has to display random number from 1 to 6 each time the button “roll” is clicked.

If both dice show the same number, change the color property of each dice and play a song.

Play randomly selected songs each time dice show the same number.

Change each dice color on each roll.

Play different song for each roll.


Exercise – dice

myObjectColor = new Color(“movieclip_name") ;

myObjectColor . setRGB (0 x FFFFFF ) ;
