What happened?
Normally Flash games run between 30 and 60 frames per second, and if we synchronize world step with frame rate, every step represents from 1/30 to 1/60 seconds. A simulation that relies on time steps is called discrete simulation , and it differs from the real world where events happen continuously, making it a continuous simulation .
Being a discrete simulation, we don't know what happens in the time between ...
