WA.camera.followPlayer(smooth: boolean): void
|
|
```
|
|

### Set spot for camera to look at
|

|
```javascript
|
|
WA.camera.set(
|
|
x: number,
|
|
y: number,
|
|
width?: number,
|
|
height?: number,
|
|
lock: boolean = false,
|
|
smooth: boolean = false,
|
|
): void
|
|
```
|

|
|

|
### Listen to camera updates
|
|
|
|
```
|
|
WA.camera.onCameraUpdate(): Subscription
|
|
```
|
|
|
|
Listens to updates of the camera viewport. It will trigger for every update of the camera's properties (position or scale for instance). An event will be sent.
|
|
|
|
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();
