Beads and Arrays

I'm writing a program that triggers a different sound every time a box on screen is clicked. I've managed to load the sounds into an array and draw a box to the screen for each sound in the array. Does anyone one know how I might assign an individual sound to each box so that when the box is clicked a sound is played? The boxes can be dragged around the screen, so the sound must play no matter where on screen the box is located.

I'd put the code to play a sound into the SonicB class. this means instead of having global arrays of Gain, Glide and SamplePlayer, just put this sound processing chain into the class and initialize it in the constructor.

the constructor would additionally take the filename of the sound file. and add a method to the class that will play the sound.

hi maleo, thanks again for taking the time to read my code. i'm still a little confused re: how to pass the file name to the constructor..

here's some code to get you started:

class SonicB {
// ...
SamplePlayer samplePlayer;
// ...
SonicB(int _id, color _c, float _xPos, float _yPos, float _size, String soundFile) {
//...
// create SamplePlayer from sound file
// create the rest of your sound chain (Gain, Glide,...)
// ac.out.addInput(...)
}
void playSound() {
// trigger samplePlayer to play the sound
}
}
