setUp property
void Function(EngineLoop loop)?
setUp
final
The application's own part of the loop: the phases and systems that
step the world the plugin acts on, and that world — in loop.world, or
a SnapshotPart added to loop.snapshots for state kept elsewhere.
Called once on every loop the suite builds, after the plugins are
installed and before a step runs; every loop after the first is then
put back to the state the first began from, through its snapshots.
Implementation
final void Function(EngineLoop loop)? setUp;
