See Example 2

See Example 3

 

Renders a player on your page based on the options established within the rave.js file. The rave.js file contains more information about the available options in the javaScript comments.

To render a player:

<script language="JavaScript" >
  makeWimpyPlayer();
</script>

To render a player with one file:

<script language="JavaScript" >
  makeWimpyPlayer("file1.mp3");
</script>

To render a player with a few files, separate each file with a "pipe" character, see Example 2.

To render a player with a few files, with each file having additional information:, see Example 3.

wimpy_getTrackInfo()

Returns: Object

See Example 6

Returns all the information for a track as an Object.

In your HTML:

<a href="javascript:;"
onClick="wimpy_getTrackInfo();">
Get info about current track.
</a>

Wimpy returns:

anObject.artist = "The tracks artist";
anObject.title = "The track's title";
anObject.whatever = "Whatever else is available"

To get info on the current track, don't include an argument

Example:

<a href="javascript:;"
onClick="wimpy_getTrackInfo();">
Get info about current track.
</a>

To retrieve information on a specific item:

Enter the a number as an argument. The number that you enter should correspond to the playlist item. For example, entering "3" as the argument will get the info for the third item in the playlist.

<a href="javascript:;"
onClick="wimpy_getTrackInfo(3);">
Get info about the third item in the playlist.
</a>

Retuns the information for the third item in the playlist will be returned.

NOTE: If the playlist is being sorted, the item may be different than the order in which the source XML playlist.

If the player has not yet started to play a track, the info for the first item in the playlist is returned.

If the player does not have anything in the playlist Wimpy will return false (boolean).

wimpy_getPlayheadPercent()

Returns: Number

 

Gets the current playhead percentage.

wimpy_setPlayheadPercent()

Returns: nothing

Sets the playhead to the specified percentage.

NOTE: This option was not designed to for use milliseconds after launching a file. In other words, some folks might be trying to use this function to "pick up" playing where a user left off last time they visited a page.

Although this kind of functionality can be achieved, it will require additional scripting to accomplish because the file must have enough data loaded before Wimpy can advance the playhead.

For example, lets say you launch a track, then immediately call this function and set the argument to 95 (meaning "set the playhead so that the track starts playing at 95%"... Since it is highly likely that the file has not been fully loaded milliseconds after launching it, Wimpy will not advance the playhead to 95%. Wimpy can only advance the playhead to a percentage that has been loaded.

This means that you will probably need to use the wimpy_getLoadPercent function before calling this "set" function in order to determine how much of the file has been loaded, and / or if it is safe to advance the playhead.

Here's a potential method for achieving this kind of functionality:

// Create a player:
makeWimpyPlayer();

// In the rave.js, add a function call inside wimpy_amReady() as:
function wimpy_amReady(retval){
    loadAndListen( "myFile.flv");
}

// Create a new function in rave.js as:
function loadAndListen(myFile){
   // Add a track to the player and launch it (so it starts to load)
   wimpy_appendPlaylist(myFile, true);
   // Pause the player immediately
   wimpy_pause();
   // Set an interval call to wait until enough data has been
   // loaded before setting the playhead position:

   ourInterval = setInterval('checkLoadStatus()', 1000);
}

// Establish variables in the global scope:
var ourInterval;
var gotoPercent = 30;

// Create function to intermittently check the load percent:
function checkLoadStatus(){
   var loaded  = wimpy_getLoadPercent();
   if(loaded > gotoPercent){
      wimpy_setPlayheadPercent(gotoPercent);
      clearInterval(ourInterval);
   }
}

 

wimpy_getPlayheadSeconds()

Returns: Number

 

Gets the playhead position in seconds.

 

 

wimpy_setPlayheadSeconds()

Returns: nothing

 

Sets the playhead to the specified second.

See "NOTE" in wimpy_setPlayheadPercent();

.

wimpy_getLoadPercent()

Returns: Number

 

Retrieves the loading status according to percent loaded (0-100).

 

 

wimpy_getLoadState()

Returns: Object

See Example 6

 

Retrieves all information associated with file loading.

The object will contain the following variables:

percent

A "float" number from 0.0 to 1.0.

Example:
0.34
(the file is 34% loaded)

 

loaded

Number of bytes loaded

Example:
5035075 (bytes)

 

total

wimpy_getPlayerState()

Returns: Object

See Example 6

Retrieves all information associated with clip playback.

The object will contain the following variables:

buffering

Boolean value indicating whether or not the track is buffering

The spinning "wait" icon is a graphic representation of this value.

 

 

bufferState

A numerical representation of the buffer status:

1 = Buffer is full
0 = Buffer is empty
-1 = Buffer is flushing

 

buffer

Number of seconds worth of media in the buffer. See also "bufferSeconds."

printTime

A nicely formatted time signature. representing the current time.

remaining_nice

wimpy_getTotalPlaylistItems()

Returns: Number

See Example 6

 

 

Returns the total number of tracks loaded into the playlist.

 

 

 

wimpy_returnPlaylistItem()

Returns all the information for a specific track loaded into the Wimpy playlist.

Wimpy returns the information as an array, where the first index of the array is a string identifying the name of the function (e.g. "wimpy_returnPlaylistItem " which allows you to distinguish between different function calls returned to the function that is defined in js_wimpy_returnOnComplete.

This function requires js_wimpy_returnOnComplete to be established within rave.js. See the comments within rave.js for how to use this feature.

<a href="javascript:;"
onClick="wimpy_returnPlaylistItem(2);"> <-- Specify the track number inside the ().

Get info about a specific track

</a>

wimpy_getPlaylistXML()

Returns: XML

See Example 6

 

 

Returns the current playlist as a string in the form of XML data.

 

 

 

 

wimpy_getPlaylist()

Returns: Array

See Example 6

 

Returns an array where each item in the array is an object. that refers to a playlist item.

Example:

returned_array[0] = playlist_item_object
returned_array[1] = playlist_item_object
returned_array[2] = playlist_item_object

 

Each "playlist_item_object" can be interpreted using the method described in "Retrieving Information."

This method is provided so that you don't have to convert the XML into a usable array or object. It should be noted that in each playlist_item_object, the <item> XML is also included in the XMLdata  variable.

wimpy_callPlugin()

Allows you to call a custom plugin.

wimpy_callPlugin(pluginID, argument)

 

Where pluginID refers to the ID name given to the plugin. The ID can be modified using Skin Machine.

Only one argument is allowed to be sent it. If your plugin requires more than one argument to be sent in, the argument must be formatted according to the method described by the plugin author. Usually this means "packaging" the multiple arguments with some kind of delimiter, such as a pip " | " or carat " ^ ".

Example:

var myPluginID = "CoolPlugin";
var arg1 = "http://path/to/something";
var arg2 = "true";
var combinedArgument = arg1 + "|" + arg2;
wimpy_callPlugin(myPluginID, combinedArgument);
