CameraAnimationsPluginImpl

class CameraAnimationsPluginImpl : CameraAnimationsPlugin, MapCameraPlugin

CameraAnimationsPluginImpl is designed to rule all the animations happening to the map driven by changing CameraOptions. It is responsible for:

Storing all the ValueAnimator's that could be run. Only specific camera animators could be used in this plugin.
Controlling animation execution - only one ValueAnimator of certain type could be run at a time. If some another animation with same CameraAnimator.type is about to start previous one will be cancelled.
Giving possibility to listen to CameraOptions values changes during animations via listeners.
If several animations of different CameraAnimator.type are running simultaneously map camera will be updated only on oldest animation update (the oldest is the one that was started first). That actually means that animation start order matters. High-level animations flyTo and easeTo will always trigger camera center animator first.

CameraAnimationsPluginImpl is NOT thread-safe meaning all animations must be started from one thread. However, it doesn't have to be the UI thread.

calculateScaleBy

open override fun calculateScaleBy(amount: Double, currentZoom: Double): Double

Calculate target zoom by applying scale

cancelAllAnimators

open override fun cancelAllAnimators(exceptOwnerList: List<String>)

Cancel all animators except ones owned by exceptOwnerList list.

cleanup

open override fun cleanup()

Called when the map is destroyed. Should be used to cleanup plugin resources for that map. Cancel all running animations and cleanup all resources (registered animations, listeners).

createAnchorAnimator

open override fun createAnchorAnimator(options: CameraAnimatorOptions<ScreenCoordinate>, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraAnchorAnimator

createBearingAnimator

open override fun createBearingAnimator(options: CameraAnimatorOptions<Double>, useShortestPath: Boolean, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraBearingAnimator. Current map camera option will be applied on animation start if not specified explicitly with options.startValue.

createCenterAnimator

open override fun createCenterAnimator(options: CameraAnimatorOptions<Point>, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraCenterAnimator. Current map camera option will be applied on animation start if not specified explicitly with options.startValue.

createPaddingAnimator

open override fun createPaddingAnimator(options: CameraAnimatorOptions<EdgeInsets>, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraPaddingAnimator. Current map camera option will be applied on animation start if not specified explicitly with options.startValue.

createPitchAnimator

open override fun createPitchAnimator(options: CameraAnimatorOptions<Double>, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraPitchAnimator. Current map camera option will be applied on animation start if not specified explicitly with options.startValue.

createZoomAnimator

open override fun createZoomAnimator(options: CameraAnimatorOptions<Double>, block: ValueAnimator.() -> Unit?): ValueAnimator

Create CameraZoomAnimator

easeTo

open override fun easeTo(cameraOptions: CameraOptions, animationOptions: MapAnimationOptions?): Cancelable

Ease the map camera to a given camera options and animation options.

flyTo

open override fun flyTo(cameraOptions: CameraOptions, animationOptions: MapAnimationOptions?): Cancelable

Fly the map camera to a given camera options.

initialize

open fun initialize()

moveBy

open override fun moveBy(screenCoordinate: ScreenCoordinate, animationOptions: MapAnimationOptions?): Cancelable

Move the map by a given screen coordinate with optional animation.

onCameraMove

open override fun onCameraMove(lat: Double, lon: Double, zoom: Double, pitch: Double, bearing: Double, padding: DoubleArray)

Called whenever camera position changes.

onDelegateProvider

open override fun onDelegateProvider(delegateProvider: MapDelegateProvider)

Provides all map delegate instances.

pitchBy

open override fun pitchBy(pitch: Double, animationOptions: MapAnimationOptions?): Cancelable

Pitch the map by with optional animation.

playAnimatorsSequentially

open override fun playAnimatorsSequentially(vararg animators: ValueAnimator)

Play given ValueAnimator's sequentially.

playAnimatorsTogether

open override fun playAnimatorsTogether(vararg animators: ValueAnimator)

Play given ValueAnimator's together.

registerAnimators

open override fun registerAnimators(vararg cameraAnimators: ValueAnimator)

Register given ValueAnimator's. Such ValueAnimator's must be created with static methods like CameraAnimationsPlugin.createCenterAnimator or similar. Only registered animations affect MapboxMap and would not even start otherwise.

removeCameraAnchorChangeListener

open override fun removeCameraAnchorChangeListener(listener: CameraAnimatorNullableChangeListener<ScreenCoordinate?>)

Remove CameraAnimatorNullableChangeListener. No updates will arrive after that.

removeCameraAnimationsLifecycleListener

open override fun removeCameraAnimationsLifecycleListener(listener: CameraAnimationsLifecycleListener)

open override fun removeCameraBearingChangeListener(listener: CameraAnimatorChangeListener<Double>)

Remove CameraAnimatorChangeListener. No updates will arrive after that.

removeCameraCenterChangeListener

open override fun removeCameraCenterChangeListener(listener: CameraAnimatorChangeListener<Point>)

Remove CameraAnimatorChangeListener. No updates will arrive after that.

removeCameraPaddingChangeListener

open override fun removeCameraPaddingChangeListener(listener: CameraAnimatorChangeListener<EdgeInsets>)

Remove CameraAnimatorChangeListener. No updates will arrive after that.

removeCameraPitchChangeListener

open override fun removeCameraPitchChangeListener(listener: CameraAnimatorChangeListener<Double>)

Remove CameraAnimatorChangeListener. No updates will arrive after that.

removeCameraZoomChangeListener

open override fun removeCameraZoomChangeListener(listener: CameraAnimatorChangeListener<Double>)

rotateBy

open override fun rotateBy(first: ScreenCoordinate, second: ScreenCoordinate, animationOptions: MapAnimationOptions?): Cancelable
