類別: Relay

定義於: packages/board/src/camera/camera-mux/relay.ts:48

Stateless camera input multiplexer that always allows inputs to pass through. This is the simplest CameraMux implementation with no filtering or state management.

備註

The Relay class provides a "transparent" mux that:

• Never blocks inputs
• Passes all inputs unchanged
• Has no internal state
• Acts as a simple conduit between input sources and camera control

Use this when you want:

• Direct, unfiltered camera control
• No animation system or input blocking
• Maximum simplicity with minimal overhead

For more advanced use cases (animations, input blocking, state management), implement a custom CameraMux or use a stateful implementation.

範例

const relay = new Relay();

// All inputs pass through unchanged
const panResult = relay.notifyPanInput({ x: 10, y: 5 });
// panResult = { allowPassThrough: true, delta: { x: 10, y: 5 } }

const zoomResult = relay.notifyZoomInput(0.5, { x: 100, y: 200 });
// zoomResult = { allowPassThrough: true, delta: 0.5, anchorPoint: { x: 100, y: 200 } }

const rotateResult = relay.notifyRotationInput(0.1);
// rotateResult = { allowPassThrough: true, delta: 0.1 }
