ActionTimer

A class to execute an action every specified msec. The functions are only start, stop and notify. notify function interrupts the timer and execute the specified action if the action isn't executing. It does nothing while the action is executing. Use QueuedActionTimer if you want to execute the action after current action process is completed.

Usage

const instance = new ActionTimer(1000);
const action = () => {
    // your function
}
instance.action = action;
instance.start();
// action is called when the callback returns true
// the timer starts from 0 again
instance.notify(() => true);
instance.stop();

// action isn't called while timer stops
instance.notify(() => true);

Example output

See example code. It executes every second but it calls notify function after 2800 msec.
