how to avoid draw() function delay before starting a new cycle?

wagnersaboia

I'm trying some tests with an analog clock using only the draw() function, by setting frameRate(1). Unfortunately, it seems that after each cycle, draw() functions causes a little wait before starting a new cycle. How can I solve this problem?

instead of using frameRate at all you could program a timer

// the number:
int i=0;

// our timer:
int timeSinceLastIncrease;

// how much time goes by till sketch increases the number again? Measured in millis:
final float timeDuration = 1000;

void setup() {
  size(480, 480);
  background(255);
  timeSinceLastIncrease=millis();
} // func 


void draw() {

  background(255);

  fill(i, 0, 0);
  text(i, 23, 23);

  if (millis() >= timeSinceLastIncrease + timeDuration) {
    i++;
    timeSinceLastIncrease=millis();
  } // if
} // func

There are also several timer libraries:

• Timing Utilities https://github.com/Lord-of-the-Galaxy/Timing-Utilities
• Timed Events Library http://multiply.org/processing/
• Countdown Timer https://github.com/dhchoi/processing-countdowntimer

...and many of discussions of timers on the forum:
