minim audioSnippet and array asignment problem
May 21st, 2010, 1:19pm  
Hello, i've run into a problem that i can't solve myslelf.
When i'm using:
Code:

        private Minim minim;
	private AudioSnippet sample;
	
	public void setup() {
		size(CANVAS_WIDTH,CANVAS_HEIGHT, JAVA2D);
		background(BG_COLOR);
		smooth();
		
		this.minim = new Minim(this); 
 		this.sample = minim.loadSnippet("04.wav");
        }

everything works fine. The problem is i want to use an array of AudioSnippets. Im trying like that:
Code:

        private Minim minim;
	private AudioSnippet samples[];
	
	public void setup() {
		size(CANVAS_WIDTH,CANVAS_HEIGHT, JAVA2D);
		background(BG_COLOR);
		smooth();
		
		this.minim = new Minim(this); 
 		this.samples[0] = minim.loadSnippet("04.wav");
       }

I get the NullPointerException. What am i doing wrong?

Worked it aroudn using:
Code:
private ArrayList <AudioSnippet> snippets_list = new ArrayList<AudioSnippet>();


I still don't know why the previous one didnt work. ??

You also need to 'new' your simple array.
