There are alternative ways to implement a game loop in JavaFX. A slightly longer (but more flexible) approach involves the Timeline class, which is an animation sequence consisting of a set of KeyFrame objects. To create a game loop, the Timeline should be set to repeat indefinitely, and only a single KeyFrame is required, with its Duration set to 0.016 seconds (to attain 60 cycles per second). This implementation can be found in the Example3T.java file in the GitHub repo.
