Hi, i am trying to playback many audio files with Minim SamplePlayer but I cannot get anything after 32th sample

Any solutions?

Also do you think it is good idea to to work with JUST processing or combination of Processing + Max/MSP or Supercollider?

Hi,

I am trying to make lines that connect shapes to be in the background but I am probably missing something.

Any help?

int numBalls = 14;

int[] drivingArray = new int[numBalls];

Ball[] balls = new Ball[numBalls];

//for (int i = 0; i < myArray.length; i++){

void setup()

{

size(displayWidth - 20, 300);

frame.setBackground(new java.awt.Color(0, 0, 0));

for (int d = 0; d < numBalls; d++) {

drivingArray[d] = int(random(0, width));

}

drivingArray = sort(drivingArray);

for (int i = 0; i < numBalls; i++) {

balls[i] = new Ball(drivingArray[i], random(height), random(5, 55), random(75, 150), random(50, 200), random(100, 255), 255);

}

}

void draw()

{

background(0);

stroke(200);

line(0, 0, width, 0);

line(0, height-1, width, height-1);

for (int i = 0; i < numBalls; i++) {

balls[i].connect(i);

balls[i].display();

balls[i].move();

}

}

class Ball {

float x, y, red, green, blue, alpha;

float diameter;

float dy = 0.63;

float dx = 0.63;

Ball(float temp_x, float temp_y, float temp_d, float temp_red, float temp_green, float temp_blue, float temp_alpha) {

x = temp_x;

y = temp_y;

diameter = temp_d;

red = temp_red;

green = temp_green;

blue = temp_blue;

alpha = temp_alpha;

}

void move() {

y += dy * map(mouseY, 0, height, 0, 1);

if (y + diameter/2 > height) {

y = height - diameter/2;

dy *= -1;

}

else if (y - diameter/2 < 0) {

y = diameter/2;

dy *= -1;

}

x += dx * map(mouseX, 0, height, 0, 1);

if (x + diameter/2 > width) {

x = width - diameter/2;

dx *= -1;

}

else if (x - diameter/2 < 0) {

x = diameter/2;

dx *= -1;

}

}

void connect(int i) {

strokeWeight(1.5);

stroke(255, 200);

if (i == 0) {

line(balls[i].x, balls[i].y, 0, height);

}

else if (i == numBalls-1) {

line (balls[i].x, balls[i].y, width, height);

line(balls[i].x, balls[i].y, balls[i-1].x, balls[i-1].y);

}

else if (i > 0) {

line(balls[i-1].x, balls[i-1].y, balls[i].x, balls[i].y);

}

}

void display() {

fill(red, green, blue, alpha);

if (y < height/2) {

ellipse(x, y, diameter, diameter);

}

else if (y >= height/2) {

rectMode(CENTER);

rect(x, y, diameter, diameter);

}

}

}

MouseX-Y when mouse is pressed

Hi, just a clarification,

when mouse is pressed mouseY reports values independently from window size? (but from actual screen size)

Is it true? I cannot find anything in documentation but it seems this is how it works (actually a nice feature!)

Thanks!

Use multiple noise() instances within one class

Hi,

I need to drive two lines contained in a class. I need some random shifting and I use noise(). If a call noise() and assign it to another variable it is moving the second line in parallel.

Probably pseydo-num generator is fixed within a class. Is there a way to overcome this? What are the suggestions from experienced programmers?

Thank you

Dimitris
