no it's not ...
you might wanna have carnivore run on a different thread ... although it will introduce some other problems it solves the speed thing (don't have carnivore ... so code's not checked):
threads at sun:
http://java.sun.com/docs/books/tutorial/essential/threads/
Code:// carnivore
Socket socket;
BufferedReader packetreader;
String packet;
int ln;
carnivoreChecker carn;
ball b1 = new ball(300,300);
float targetX, targetY, targetR;
void setup() {
framerate(25);
size(600, 400);
textFont(loadFont("fonts/Univers45.vlw.gz"), 14);
try {
socket = new Socket("127.0.0.1", 6667);
packetreader = new BufferedReader( new InputStreamReader(socket.getInputStream()) );
} catch(IOException e) { println(e); }
carn = new carnivoreChecker();
carn.start();
}
void loop(){
background(0,0,0);
carn.draw();
b1.update();
}
void mousePressed(){
b1.myX = ln;
b1.myY = ln;
}
class carnivoreChecker
extends Thread {
public boolean running = false;
carnivoreChecker(){
targetX = int(random(0, width));
targetY = int(random(0, height));
}
public void start ()
{
this.running = true;
super.start();
}
public void run ()
{
while (running){
this.update();
try { sleep((long)(1000/25.0)); } // give system some air ... //
catch (Exception e) {}
//println("re-run carnivore");
}
}
void update(){
if (packetreader != null) {
try {
packet = packetreader.readLine();
//println("carnivore packet: " + packet);
} catch(IOException e) { println(e);}
//b1.myX = ln;
}
}
void draw()
{
if (packet != "" && packet != null) {
text("data from Carnivore", 10, 30);
fill(50,50,50);
text(packet, 10, 50);
String list[] = splitStrings(packet);
text(list[1], 10, 90);
text(list[3], 10, 130);
ln = packet.length();
text("packet size:",10,190);
text(ln, 100, 190);
}
}
public void quit()
{
this.running = false;
super.stop();
}
}
class ball{
float myX, myY, distanceX,distanceY;
int originX, originY;
ball(int x,int y){
originX = 0;
originY = 0;
myX = x;
myY = y;
}
void update(){
distanceX = originX-myX;
distanceY = originY-myY;
myX += distanceX/20;
myY += distanceY/10;
stroke(255);
point (myX,myY);
}
}
public void stop()
{
carn.quit();
}
