Tips and FAQ's

Q - What is the best way for me to time events with sound effects or the end of songs?

A - You have two options listed below. Option 1 is for long sound effects like background music, but just one at a time. Option 2 is better suited to sound effects.

Option 1: If you are playing a longer sound like background Music, you can use the MediaPlayer and a Song object to play it. This gives you access to all sorts of details regarding the sound file. You can only play one sound through the media player at a time.

Here is an example program that demonstrates using the Song class and MediaPlayer:

Option 2: Create a SoundEffectInstance and use it to play your sound file. You can play multiple sounds at once, and determine whether a sound effect is playing or not.

Here is a good tutorial on how to use it:
