Trying To Figure Out How to Make My Lines Move Independently

clintonva32

Hi Processing World!

I'm still a newbie here, and never have coded something substantial in my life. I'm wondering if I can get some help in figuring out how to make my lines move independently from each other and go off of different angles, instead of just bouncing back off the screen in the same direction. Either I need to have them rotate as they hit the side of the screen, or I need point X to follow point Y. Not sure what my solution would be but I hope someone here can help.

Thank you,

Clinton

Bouncer a; Bouncer []c= new Bouncer [150]; import processing.sound.*; AudioIn in; Amplitude amp; void setup(){

size( 1500,1500); for (int i=0; i<c.length;i++){ c[i] = new Bouncer(random(-8,8), random (-8,8), random(255)); }

}

void draw(){

background(0,.000005);

for (int i=0; i<c.length;i++){ c[i].display(); c[i].bounce(); }

}

class Bouncer {

float r, g, b, s, xpos, ypos, xpos2, ypos2, xspeed, yspeed; Bouncer(float tempxspeed, float tempyspeed, float tempr) {

xspeed = tempxspeed;
yspeed = tempyspeed;
xpos = width/2;
ypos = height/2;
xpos2 = width/4;
ypos2 = height/4;
r = tempr;
g = random(255);
b = 255;
s = 5;

}

void display() {

stroke(255);
fill(255);
line(xpos, ypos, xpos2, ypos2);

}

void bounce() {

if ( xpos > width - s/2 || xpos < s/2 ) {
  xspeed = xspeed * -1;
}

if ( ypos > height - s/2 || ypos < s/2 ) {
  yspeed = yspeed * -1;
}

if ( xpos2 > width - s/2 || xpos2 < s/2 ) {
  xspeed = xspeed * -1;
}

if ( ypos2 > height - s/2 || ypos2 < s/2 ) {
  yspeed = yspeed * -1;
}

xpos = xpos + xspeed;
ypos = ypos + yspeed;
xpos2 = xpos2 + xspeed;
ypos2 = ypos2 + yspeed;

} }

each line has two ends. You use xspeed and yspeed for BOTH. I changed that by using xspeed2 and yspeed2 for the 2nd end now.

import processing.sound.*; 

// Bouncer a; 

Bouncer []c= new Bouncer [150]; 

AudioIn in; 
Amplitude amp; 

void setup() {

  size( 1500, 1000);

  for (int i=0; i<c.length; i++) { 
    c[i] = new Bouncer(random(-8, 8), random (-8, 8), random(255));
  }

  background(0, .000005);
}

void draw() {

  // if (random(100)>96)
  background(0, .000005);

  for (int i=0; i<c.length; i++) { 
    c[i].display(); 
    c[i].bounce();
  }
}

class Bouncer {

  float r, g, b, // color !!
    s, 
    xpos, ypos, 
    xpos2, ypos2, 
    xspeed, yspeed, 
    xspeed2=random(-8, 8), yspeed2=random(-8, 8);  // !!!!!!!!!!

  Bouncer(float tempxspeed, float tempyspeed, 
    float tempr) {

    xspeed = tempxspeed;
    yspeed = tempyspeed;

    xpos = width/2;
    ypos = height/2;
    xpos2 = width/4;
    ypos2 = height/4;

    r = tempr;

    g = random(255);
    b = 255;
    s = 15;
  }

  void display() {

    stroke(r, g, b);
    //fill(255);
    line(xpos, ypos, 
      xpos2, ypos2);
  }

  void bounce() {

    if ( xpos > width - s/2 || xpos < s/2 ) {
      xspeed = xspeed * -1;
    }

    if ( ypos > height - s/2 || ypos < s/2 ) {
      yspeed = yspeed * -1;
    }

    if ( xpos2 > width - s/2 || xpos2 < s/2 ) {
      xspeed2 = xspeed2 * -1;

Hey thanks for this! Quick question... I'm trying to do a sound experiment and I'd like to figure out how to manipulate the lines via sound. My idea is that each time the input is triggered, all of the lines will be shot to the edges of the screen... Like gravity took over the lines and are holding them close to the edge when the sound is hit.

Let me know if this makes sense and if it's possible! Thanks.

Chrisir

Sure it’s possible

Just look at examples of library minim and look at beat detection or some analysis tools for sound

Thanks for this, I'm going to try work on a few things now. You guys are awesome!
