Counting Down
Feb 7th, 2008, 11:02pm  
Hi there.  I'm not sure if this is the right forum for this or not, but I just started using processing and am interested in messing around with the idea of counting up and counting down.

Is there a simple way that I can't find to do the following:

Display a number, let's say 1500.

At timed intervals, like 1 second, the display counts down to 1499.  I can't figure a way out without looping it somehow.

Any help whatsoever would be greatly appreciated!

Code:

int start;
int period;
void setup()
{
  //normal setup stuff
  start=millis();
  period=1500;
}

void draw()
{
  int timeleft=period=(millis()-start)/1000;
  println(timeleft);
  if(timeleft<=0)
  {
    //countdown is 0. (or less)
  } 
}
