Hi , I start Processing and I made a code to play a piano note, i run the code , but when i press the key to play the song , i have an error : NullPointer Exeption and === Minim Error === === Couldn't load the file G.mp3

This is my code : import ddf.minim.*; import ddf.minim.analysis.*; import ddf.minim.effects.*; import ddf.minim.signals.*; import ddf.minim.spi.*; import ddf.minim.ugens.*;

import ddf.minim.*;

Minim minim; // création d'un objet de la classe Minim

AudioPlayer G;

void setup() {

minim = new Minim(this); // 'this' fait référence à l'application en cours

G = minim.loadFile("G.mp3");

}

void draw() {

background(128);

if (key == 'u') G.play(); // key est la dernière touche activée du clavier

if (key == 'p') G.pause();

}

void stop() {

G.close();

minim.stop();

super.stop();

}

I'm french , I hope you to help me asap! :)

    is the file name correct?

    Is the file in the data directory or the sketch directory?

    You can drag the file onto the pde window or use the add file menu option to place it correctly.

    G is a terrible name for a variable. It should be lower case for a start, but choose something longer and more descriptive.

    hum, ok I'll try

    Now that's say :

    === Minim Error === === Couldn't load the file SOL.mp3

    What line is showing the error? Please also format the code above. Edit your post, edit your code and hit ctrl+o.

    Double check the file name and the location. That error says that your filename or location is incorrect.
