Sound controller In this tutorial, we will learn, - To attach external .mp3 file to swf
- To create preloader for sound file
- To create play / stop button
- Volume controller
- Balance (Pan) controller
To Achieve all the above, we will be using built-in sound class to control sounds in a SWF file. Let's create all the graphics first. Play / Stop button - Select 'Frame1'. Using the rectangular tool in the tool box, create a triangle on your canvas, similar to the one shown in the above '.swf' file.
- Convert this triangular vector shape to button symbol - Select this triangular shape and press 'F8' key. 'Convert to symbol' window pops-up, type 'play_btn' in the Name field and select button 'Type'. Click 'OK'. Your play button is ready.
- Similarly create 'stop_btn' symbol.
Slider for control - Select 'Frame1'. Draw a rectangle on your canvas of 5px width and 18px height.
- Convert this 'rectangle' to a movie clip.
- Give an instance name, 'dragger' to this movie clip in the 'properties window'
- Draw a horizontal line of lenght 150px. Place it under and to the left of 'dragger' as shown above in flash / .swf file.
- Select both - 'line' and 'dragger' movie clip and press 'F8' key and convert this to a 'movie clip' symbol.
- Now select the 'slider' movie clip and give an instance name - 'mySlider' in the properties window.
- Your controller is now ready.
- Right click this controller in your library panel and duplicate the same. Name it 'pan_controller'
- Drag this pan_controller to your canvas. Double click to enter inside movie clip. Align 'dragger' movie clip to the center of the horizontal line.
Place 2 dynamic text fields one beside the other on your canvas and give them variable names - 'load_sg' and 'down_sg' in your properties window. You can now align all your movie clips and buttons according to your design requirements on your canvas. Add a .mp3 file in the folder where this flash file resides and rename it to 'sound2' And now we are ready to add actionscrips and get all the symbols to work. :) Add a new layer in the timeline panel and name in 'actions'. Select 'Frame1' in the actions layer and add below script in 'Actions' window.
mySound = new Sound();
mySound.loadSound("sound2.mp3", false);
onEnterFrame = function()
{
var downloaded:Number = _root.mySound.getBytesLoaded();
var total:Number = _root.mySound.getBytesTotal();
_root.down_sg = Math.floor(downloaded/total*100);
if (downloaded != total)
{
_root.load_sg = "downloading song...";
}
else
{
complete = 1;
_root.load_sg = "";
_root.down_sg = "";
}
} |
Select play button and add the below script in your 'Actions' window
on (release)
{
_root.mySound.start(0, 99);
} |
Select play button and add the below script in your 'Actions' window
on (release)
{
_root.mySound.stop();
} |
Double click your volume control movie clip and add a new layer, call it 'actions'. Select 'Frame1' of actions layer and add the below code in your 'Actions' window
this.ratio = 0;
ratio = _root.mySound.getVolume();
trace("ratio: " + ratio);
_root.mySound.setVolume(ratio);
dragger.onPress = function()
{
this.startDrag(true, 0, 0, line._width, 0);
this.onEnterFrame = function()
{
ratio = Math.round(this._x*100/line._width);
};
};
dragger.onRelease = dragger.onReleaseOutside = function()
{
stopDrag();
trace("ratio: " + ratio);
_root.mySound.setVolume(ratio);
}; |
Double click your pan control movie clip and add a new layer, call it 'actions'. Select 'Frame1' of actions layer and add the below code in your 'Actions' window
this.ratio = 0;
ratio = dragger._x;
trace("ratio: " + ratio);
dragger.onPress = function()
{
this.startDrag(true, 0, 0, line._width, 0);
this.onEnterFrame = function()
{
ratio = Math.round(this._x*100/line._width);
/};
};
dragger.onRelease = dragger.onReleaseOutside = function()
{
stopDrag();
trace("ratio: " + ratio);
_root.mySound.setPan(ratio);
}; |
