loop |
Description Set theAudioPlayer to loop some number of times.
If it is already playing, the position
will not be reset to the beginning.
If it is not playing, it will start playing.
If you previously called this method and then paused the
AudioPlayer, you can resume looping
by using the result of getLoopCount() as
the argument for this method.
To loop indefinitely, use loop().
Signature void loop(int num) void loop() Parameters num — int: the number of times to loopReturns None Related AudioPlayerExample /**
* This sketch demonstrates how to use the <code>loop(int)</code> method of a <code>Playable</code> class.
* The class used here is <code>AudioPlayer</code>, but you can also loop an <code>AudioSnippet</code>.
* When you call <code>loop(int)</code> it will make the <code>Playable</code> loop for the number of times
* you specify. So, <code>loop(3)</code> will loop the recording three times, which will result in the recording
* being played 4 times. This may seem odd, but it is consistent with the behavior of a JavaSound <code>Clip</code>.
* If you want to make it stop looping you can call <code>play()</code> and it will finish the current loop
* and then stop. Press any of the number keys to make the player loop that many times. Text will be displayed
* on the screen indicating your most recent choice.
