Built-in Loom state / Loom Docs

Loom adds a read-only loom object to every bridge. You do not declare it in C#.

const bridge = useBridge();

bridge.loom.currentSceneName;
bridge.loom.viewportWidth;
bridge.loom.viewportHeight;
bridge.loom.devicePixelRatio;
bridge.loom.bridgeReady;

Fields

Field	Type	Meaning
`currentSceneName`	`string`	The active Unity scene name
`viewportWidth`	`number`	Current UI viewport width in CSS pixels
`viewportHeight`	`number`	Current UI viewport height in CSS pixels
`devicePixelRatio`	`number`	Current device pixel ratio
`bridgeReady`	`boolean`	Whether the bridge has completed startup

Usage

For example, select a compact layout when the game viewport is under 900 CSS pixels:

const bridge = useBridge();

const compact = () => bridge.loom.viewportWidth < 900;

Ownership

Loom updates these fields when the active scene, viewport size, DPI, or bridge connection changes.
