Concurrency Overview In Verse
An expression in Verse can be either immediate or async. This describes the time an expression can take to evaluate relative to simulation updates.
Think of a simulation update as when a new frame is shown.
There are cases when multiple simulation updates can occur before a new frame, such as if an online game goes out of sync with the server.
| immediate | async |
|---|---|
| An immediate expression evaluates with no delay, meaning that the evaluation will complete within the current simulation update. | An async expression has the possibility of taking time to evaluate, but doesn’t necessarily have to. An async expression may or may not complete in the current simulation update, or in a later one. |
Async Contexts
Async expressions can be used in any Verse code that has an async context.
