|
WA.camera.onCameraUpdate(): Subscription

The event has the following attributes :
|
|
* **x (number):** coordinate X of the camera's world view (the area looked at by the camera).
|
|
* **y (number):** coordinate Y of the camera's world view.
|
|
* **width (number):** the width of the camera's world view.
|
|
* **height (number):** the height of the camera's world view.
|
|
|
|
**callback:** the function that will be called when the camera is updated.
|
|
|
|
Example :
|
|
```javascript
|
|
const subscription = WA.camera.onCameraUpdate().subscribe((worldView) => console.log(worldView));
|
|
//later...
|
|
subscription.unsubscribe(); |
