possible to get input during setup? (Read 963 times)

Phillip M. Feldman YaBB Newbies Offline Posts: 11	possible to get input during setup? Feb 28^th, 2010, 1:31pm My son wrote a program that can run in either of two modes. He would like to allow the user to select one of these two modes by pressing a key during the setup. But, it seems as though `keypressed` does not get invoked until after setup has been called. Is there any way to get user input while setup is running?

thats not the way i would do it.
if you have different modes, create an int variable, where 0 is undefinied and 1-x are your different modes.
So when starting the programm you are in mode = 0.
i dont know how the programm works, but maybe you use a switch or "ifs" to execute the different modes.
so the first mode 0 would print a screen saying something like "please select mode, press key 1 or 2"
by pressing the keys you change the int variable. and the next mode you definied in your switch would be called.

hope that makes sense somehow, if not, i will make an example.

int mode = 0;
void draw(){
  switch( mode ){
    default:
    case 0:
      background(0);
      break;
    case 1:
      background(128,0,0);
      break;
    case 2:
      background(0,0,128);
      break;
  }
}
void keyPressed(){
  if( key == '1' && mode == 0){ mode = 1; }
  if( key == '2' && mode == 0){ mode = 2; }
}

I made an example anyway. Grin
