Is there a problem with keyReleased() ?

keyPressed() is colored red in the editor,
but
keyReleased() is NOT colored red in the editor. Why ?

How to pause the execution of a program ?

To pause/resume by pressing/releasing 'z',
is the following section of code OK ?

void keyPressed() {
 if (key == 'z' || key == 'Z') {
   noLoop();  
 }
}

void keyReleased() {
 if (key == 'z' || key == 'Z') {
   loop();  
 }
}

Is there be a better way ? a simpler way ?

Thanks if you can help..

Hi! Well, on the game i am creating, i've actually created its own little pause menu, with images, boxes, text and code.

Basically, to pause the menu you can create a boolean...

Code:

boolean pause = false;

void setup()
{
  size(640, 480);
  frameRate(50);
}

void draw()
{
if(pause == true){
  background(0);
}else{
  background(255);
}
}

void keyPressed()
{
 if(keyCode == ENTER){
    if(pause == false){
   pause = true;
}else{
   pause = false;
}     
}
}
 

If Its paused, it will make the background black, if its unpaused, it will turn the background white.

If you wish to continue developing on this, its easy enough to add boxes, menu's and even images. On my pause menu i have a series of images, which i have worked out the code for so when you hover over the image, it changes the image to another image, which is the same, but has a different colour. This then looks like a rollover and adds effect.

Thanks,
Steve.
