// Example 10-4: Implementing a timer int savedTime; int totalTime = 5000; void setup() { size(200, 200); background(0); savedTime = millis(); } void draw() { // Calculate how much time has passed int passedTime = millis() - savedTime; // Has five seconds passed? if (passedTime > totalTime) { println("5 seconds have passed!"); background(random(255)); // Color a new background savedTime = millis(); // Save the current time to restart the timer! } }
