excaliburjs/Excalibur v0.14.0 on GitHub

Breaking Changes

Triggers now have a new option bag constructor using the ITriggerOptions interface. (#863).
update event replaced with postupdate event
CollisionEvent replaced by PreCollisionEvent
getDrawWidth() and getDrawHeight() replaced with the getters drawWidth and drawHeight
PointerEvent.x and PointerEvent.y replaced with PointerEvent.pos

Automatic HiDPI screen detection and scaling in excalibur internals to correct blurry bitmap rendering on HiDPI screens. This feature can optionally be suppressed with IEngineOptions.suppressHiDPIScaling.
Added new line utility Line.normal() and Line.distanceToPoint (#703)
Added new PolygonArea utility PolygonArea.getClosestFace(point) (#703)
Triggers now fire an EnterTriggerEvent when an actor enters the trigger, and an ExitTriggerEvent when an actor exits the trigger. (#863)
Actors have a new events CollisionStart which when 2 actors first start colliding and CollisionEnd when 2 actors are no longer colliding. (#863)
New camera strategies implementation for following targets in a scene. Allows for custom strategies to be implemented on top of some prebuilt
- LockCameraToActorStrategy which behaves like LockedCamera and can be switched on with Camera.strategy.lockToActor(actor).
- LockCameraToActorAxisStrategy which behaves like SideCamera and can be switched on with Camera.strategy.lockToActorAxis(actor, ex.Axis.X)
- ElasticToActorStrategy which is a new strategy that elastically moves the camera to an actor and can be switched on with Camera.strategy.elasticToActor(actor, cameraElasticity, cameraFriction)
- CircleAroundActorStrategy which is a new strategy that will follow an actor when a certain radius from the camera focus and can be switched on with Camera.strategy.circleAroundActor(actor)

Trigger have been rebuilt to provide a better experience. The trigger action only fires when an actor enters the designated area instead of every frame of collision. (#863)
Triggers can now draw like other Actors, but are still not visible by default (#863)

Body.wasTouching has been deprecated in favor of a new event type CollisionEnd (#863)
SideCamera and LockedCamera are deprecated in favor of camera strategies

Fixed odd jumping behavior when polygons collided with the end of an edge (#703)
