Module settings 

The player’s settings: the engine’s (how fast dialogue text is revealed, whether the game fills the screen, the color theme, the music and sound volumes, the frame cap and the layout picked) and the game’s own (Settings::game, a GameSettings). Ctx loads them with its storage, from one record under SETTINGS_KEY in the profile in use, whose form the game decides (GameSettings::to_ron); it saves them when they change (Ctx::change_settings). Key bindings are saved apart.

Structs

Background

What a game does while its window has no focus (GameSettings::BACKGROUND): whether it pauses, and what its sound does. A game writes it from KEEP_RUNNING: Background::KEEP_RUNNING.paused().muted().

Settings

Everything an options screen sets: the engine’s settings and the game’s. The defaults are a new player’s.

Enums

BackgroundAudio

What the game’s sound does while its window has no focus.

TextSpeed

How fast dialogue text is revealed.

Constants

DEFAULT_VOLUME

The volume settings’ default. Tunable.

MAX_VOLUME

The loudest volume setting; 0 is silent.

SETTINGS_KEY

Storage key under which the settings are saved (Settings::to_ron).

Traits

GameSettings

The settings a game adds to the engine’s, and the saved form of both: one record, so the game decides its form (and keeps the one it has always written).
