An important aspect of games and simulations is specifying the order and overlap of operations that take time. Need two or two hundred monsters all acting simultaneously? Planning a swarm of robots that can march in (or out of) step? Thinking about a fleet of spaceships that invade over time?
Time-flow control is at the heart of the Verse programming language, and this is accomplished with concurrent expressions.
You could say that time flow is a type of flow control, but where control flow is about the order in which a computer executes instructions based on the order of expressions in the program, time flow controls the execution in time, not sequence, based on how concurrency expressions are used.
Time flow is another way of saying concurrency.
