visibilityUsage top-level constant

String const visibilityUsage

What flutter3d help visibility prints.

Implementation

const String visibilityUsage = '''
usage: dart run flutter3d_build:visibility [--cell <metres>] <level.json> ...

Bakes which cells of each level can see which into <level>.visibility.json
beside it, the sidecar LevelLoader reads. Deterministic: two bakes of one
level are the same bytes, so a committed table that differs from a fresh
bake is a level nobody re-baked.

  --cell <metres>   the side of a cell; default 3

Exit codes: 0 every level baked; 1 one could not be read; 2 usage.
''';
