[Flash Basic theory Lesson 04] Make Music player [sound class]

Back to "flash Basic Theory Class-Catalog"

Train of thought: sound playback, stop, pause implementation, very simple.

Step 1:

First put three buttons, the instance name is "Start_btn" "pause_btn" "stop_btn";

Then import a sound file into the library;

When the import is complete, right-click the sound file in the Library-> Link-> Check "for ActionScript

Export and "Export in first frame", enter a name, such as "Cannon", in the identifier.

Step 2:

Join as code layer:

var mysound:Sound = new Sound();
//让mysound具有Sound类的属性和方法

mysound.attachSound("Cannon");
//mysound链接到库中名为"Cannon"的声音元件

Start_Point = 0;
//设置播放的起点位置

play_btn.onRelease = function() {
mysound.start(Start_Point/1000);};
//播放按钮：从起点位置开始播放声音，因为要接收秒数，所以要除1000

pause_btn.onRelease = function() {
Start_Point = mysound.position;
mysound.stop();};
//暂停按钮：先保存当前播放到的位置为起点，然后停止播放

stop_btn.onRelease = function() {
Start_Point = 0;
mysound.stop();};
//停止按钮：将起点位置设为0，然后停止播放

Flash Charging: Common properties and methods of sound class

(1) sound.attachsound ("Idname"): sound objects attached to sound components

mysound.attachSound("Cannon")

(2) Sound.start (playback starting point, cycle times): Start playing sound

mysound.start(5,3)
//从5秒钟位置开始播放，循环三次
mysound.start()
//从0秒钟位置开始播放，循环一次

(3) Sound.stop ("Idname"): Stop playing sound

mysound.stop()
//停止全部声音

(4) Sound.setvolume (1~100): Set volume

mysound.setVolume(50)
//设置音量为50

(5) Sound.getvolume (): Get volume Set value

mysound.setVolume(33)
trace(mysound.getVolume())
//返回33
