start/stop/pause processing?

i am writing a program for a ping pong game which pauses/starts/stops the ball bouncing when the key 's' is pressed... i.e press 's', the game stops/pauses. by pressing 's' again the game continues. so far im using a boolean statement which pauses the game ok but how do i get it to continue when i press 's' again?

so far this is roughly what i have:

boolean matched = true;

void draw()

{

if (matched = true)

{

do this

}

void keyPressed()

{

if (key == 's')

{

matched = false;

xDirection = 0;

yDirection = 0;

}

You can use noLoop() to stop Processing from calling draw()! And loop() to resume it.
Internal variable looping is true if callback draw() is active; false otherwise.

void keyPressed() {
  final int k = keyCode;

  if (k == 'S')
    if (looping)  noLoop();
    else          loop();
}

If you not want to use loop()/noLoop(), you can make a boolean and use boolean = !boolean to alter it states each keyPressed call, like (not tested):

boolean run = true;

void draw() {

if (run){

letsPlay()

}else {

xDirection = 0;

yDirection = 0;

}

void keyPressed()

{

if (key == 's')

run = !run;

}
