Class: EnvironmentSystem

Defined in: packages/iwsdk-environment/src/index.ts:63

The per-frame tick.

Neither director owns a loop, so something has to drive them, and on IWSDK that something is a system - which means the environment stops advancing when the session loses focus, exactly like the rest of the app. registerEnvironment registers this for you; it is exported so an app that builds its own system schedule can place it deliberately.

IWSDK hands a system its delta in SECONDS and the directors take milliseconds. That conversion happens here, once.
