There is only one way. One must, first of all, understand that
discrete motion is a series of jumps. In a discrete universe, there is
only one speed and that speed is c. Nothing can move slower or faster.

If a speed is measured to be less than c at the macroscopic level, it
is really a series of jumps and rests at the micro-level. Every jump
occurs at c. Since there is only one speed, nature can only use
probability to determine when there should be a jump and when there
should be a rest. The rule is simple: in the long run, energy must be
conserved.

The secret is simple. Single speed, single interaction time,
probability and conservation principle. This is the only way
Pythagoras theorem will work in a discrete universe. And it only works
approximately. But in the end energy must be conserved. Think about
it.

Regardless of what you've heard from the discrete physics fanatics, a
discrete universe is necessarily probabilistic. There is no other way.
