4.3 Time

+ +

In the context of Sly, time is not the seconds that are passing in the +real world, but the virtual clock that is ticking within the game +loop. This manual refers to a “tick” as the smallest unit of time. +There are a user-defined amount of ticks in a real world second, but +by default it is 60. +

+

Sly includes several useful modules for working with time. Coroutines +are procedures that can be paused and resumed, agendas are procedure +schedulers, and signals built atop both agendas and coroutines to +provide a high-level functional reactive programming API. +

+

For most use-cases, the signal module should be used exclusively, but +the agenda and coroutine modules are useful for building new +high-level abstractions. +

+ + + + +
• Signals:  Functional reactive programming. +
• Coroutines:  Cooperative multi-tasking. +
• Agendas:  Deferred procedure scheduling. +
