#lynx: setObserverFrameRate() static method

The lynx.setObserverFrameRate method can be used to set the frequency of exposure detection.

#grammar

setObserverFrameRate(options?: Options): void;

#Parameters

#options

interface Options {
  forPageRect?: number;
  forExposureCheck?: number;
}

Specify exposure detection frequency:

• forPageRect: unit fps, specifies the minimum time interval for detecting LynxView position changes. Defaults to 20.
• forExposureCheck: unit fps, specifies the minimum time interval for detecting the visibility of the target node. Defaults to 20.

#return value

None (undefined).

#Precautions

When LynxView will not have position changes, such as full-page scenarios, you can set forPageRect to 0 to stop detecting position changes of LynxView. However, in the card scene, setting forPageRect to 0 will cause the exposure of the Lynx card to fail in the sliding scene. For details, please refer to Exposure Ability.
