You are probably looking for something like this..

void keyReleased()

{

if ( key == 'a' )

{

do what you want to do

}

in what ways randomness will occur?

you have to use rectangular() and random()

something like this? -

void keyReleased()

{

if ( key == 'a' )

  {
    float randX=random(0,width-100); //generate a random float between 0 and width-100
    float randY=random(0,height-100);

rect(randX,randY,100,100);

}
}

Just don't clear the background in draw() for same surface

Thanks a lot for very quick answers but it's not like this.

rect(randX,randY,100,100); > here it's all the time the same size i want when you tape a the same surface but not the same size (exemple one rect : 100,50 and the next will be 50,100)

if i got it right...

use what kwokpan wrote but switch the random function in rect(x, y, randWidth, randHeight)

Don't forget to use the rectMode() http://processing.org/reference/rectMode_.html

It might be useful to you
