Built-in Loom state / Loom Docs

Every bridge includes a small loom state object maintained by Loom. You do not declare it yourself.

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

Use built-in state for responsive UI and connection-aware screens:

const bridge = useBridge();

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

Ownership

The loom object is read-only from the UI. Loom updates it as the Unity scene, viewport, DPI, and connection state change.
