Class Timer

java.lang.Object
org.openpatch.scratch.Timer
public class Timer extends Object
A timer counting game time in seconds, like Scratch's timer: it stops while the game is paused and runs faster at a higher game speed, so it agrees with everything else that happens in ticks. Every stage and sprite has one (getTimer()); make more as fields with new Timer(). 
private Timer shooting = new Timer();

public void run() {
  if (this.isKeyPressed(KeyCode.SPACE) && this.shooting.every(0.25)) {
    this.shoot();
  }
}
