Updating after a some time on all frameCounts?

For time we can use millis() or frameCount: If you pick frameCount, remember that draw() is called back around 60 FPS. So, if you wish for your fish to turn around between 5 to 10 seconds you could use this: nextFrameChange = frameCount + (int) random(5 * 60, 10 * 60); Then keep polling the value of frameCount until it reaches nextFrameChange: if (frameCount >= nextFrameChange) swapDirection();

You pick another value for nextFrameChange only after frameCount reached current nextFrameChange: if (frameCount >= nextFrameChange) swapDirection(); It’s inside funtion swapDirection() that you change nextFrameChange: void swapDirection() { speed *= -1; nextFrameChange = frameCount + 60 * (int) random(5, 11); // 5s to 10s range } Anyways, I did a demo sketch that has a class Fish w/ methods such as display(), update(), bounce(), touchedBoundary(), etc.: Swimming_Fish.pde /** * Swim…
