Although there are a handful of controls that we can add to this custom audio player, this section will demonstrate the concept by adding the most basic control for multimedia, which is the play and pause buttons.
Adding a play and pause button
To begin, we will need to first move and resize our title field within our Flash application, so that it can hold more text than “Hello World”. We can then make room for some new controls that will be used to control the playback of our audio file. Again, the design of each of these components is subjective, but what is important is the MovieClip instance hierarchy, which will be used within our ActionScript code. Before we begin, we will need to create a new layer in our TIMELINE that will be used to place all AudioPlayer objects. We will call this new layer player:
Creating a base button MovieClip
Our base button will simply be a rounded rectangle, which we will then add some gradients to, so as to give it depth. We can do this by first creating a rounded rectangle with a vertical linear gradient fill as follows:
We can now give it some very cool depth by adding a smaller rounded rectangle within this one, and then orient the same gradient horizontally. An easy way to do this is to copy the original shape and paste it as a new shape. Once we have a new copy of our original rounded rectangle, we can navigate to Modify | Shape | Expand fill, where we will then select Inset, change our Distance to 4px, and then click on OK. After doing this, you will realize how such a simple contrast in gradients can really bring out the shape.
After we have our new button shape, we will then need to create a new MovieClip, so that we can reuse this button for both the play and pause buttons. To do this, simply select both the rounded rectangle regions, and then choose Modify | Convert to Symbol in the Flash menu. We are going to call this new movie clip mcButton.
Now that we have a base button MovieClip, we can now add the play and pause symbols to complete the play and pause buttons.
Adding the PlayButton movie clip
The first button that we will create is the play button, which simply consists of a sideways triangle (icon) with the button behind it. To do this, we will first create a new movie clip that will hold the button we just created, and the play icon. We can do this by first clicking on the mcButton movie clip, and then creating a new movie clip from that by selecting Modify | Convert to Symbol. We will call our new movie clip mcPlayButton.
What we are really doing here is creating a parent movie clip for our mcButton, which will allow us to add new specific elements. For the play button, we simply want to add a play symbol. To do this, we first want to make sure that we are within the mcPlayButton movie clip by double-clicking on this symbol, so that our breadcrumb at the top of the stage looks as follows:
Our next task is to modify our timeline within this movie clip so that we can separate the icon from the button. We can do this by creating two new layers within our timeline, called button (which will hold our button) and icon (which we will create in the next section).
We are now ready to start drawing the play icon.
Drawing a play icon
To draw a Play icon, we will need to first select the PolyStar Tool by clicking and holding on the tool until you can select the PolyStar Tool.
This tool will allow us to create a triangle, which we will use for the play icon in our play button. But before we can start drawing, we need to first set up the PolyStar Tool so that it will draw a triangle. We can do this by clicking on the Options button within the Properties tab, which will then bring up a dialog, where we can tell it to draw a polygon with three sides (triangle).
After we click on OK, we will then need to change the fill color of this triangle, so that it is visible on our button. We will just change the fill color to Black. We can then move our cursor onto the stage where the button is, and then draw our triangle in the shape of a play button icon. Remember, if you do not like the shape of what you made, you can always tweak it using the transform tool. When we are done, we should have something that resembles a play button!
Our next task is to create a pause button. Since we have already created the play button, which is similar to the pause button except for the icon, we can use a handy tool in Flash that will let us duplicate our play button, and then modify our duplication for the pause button icon.
Creating a pause button from the play button
In order to create our pause button, we will first need to duplicate our play button into a new movie clip, where we can change the icon from play to pause. To do this, we will first direct our attention to the library section of our Flash IDE, which should show us all of the movie clips that we have created so far. We can find the LIBRARY by clicking on the button on the right-hand side of our workspace.
To create a duplicate, we will now right-click on the mcPlayButton movie clip, and then select the option Duplicate.
This will then bring up a dialog very similar to the dialog when we created new symbols, but this time, we are defining a new movie clip name that will serve as a duplicate for the original one. We will call our new movie clip duplicate mcPauseButton.
Now that we have created our duplicate movie clip, the next task is to change the icon within the pause button. We can do this by opening up our mcPauseButton movie clip by double-clicking on that name within the Library. At this point, we can now change the icon of our pause button without running any risk of also modifying the play button (since we created a duplicate). When we are done, we should have a complete pause button.
We now have play a nd pause buttons that we will use to link to our AudioPlayer class.
