Breaking Changes

• Actor Drawing: ex.Actor.addDrawing, ex.Actor.setDrawing, onPostDraw(), and onPreDraw() are no longer on by default and will be removed in v0.26.0, they are available behind a flag ex.Flags.useLegacyDrawing()

  • For custom drawing use the ex.Canvas

• ex.Actor.rx has been renamed to ex.Actor.angularVelocity

• Rename ex.Edge to ex.EdgeCollider and ex.ConvexPolygon to ex.PolygonCollider to avoid confusion and maintian consistency

• ex.Label constructor now only takes the option bag constructor and the font properties have been replaced with ex.Font

  const label = new ex.Label({
    text: 'My Text',
    x: 100,
    y: 100,
    font: new ex.Font({
      family: 'Consolas',
      size: 32
    })
  });

• ex.Physics.debug properties for Debug drawing are now moved to engine.debug.physics, engine.debug.collider, and engine.debug.body.

  • Old debugDraw(ctx: CanvasRenderingContext2D) methods are removed.

• Collision Pair's are now between Collider's and not bodies

• PerlinNoise has been removed from the core repo will now be offered as a plugin

• Legacy drawing implementations are moved behind ex.LegacyDrawing new Graphics implemenations of Sprite, SpriteSheet, Animation are now the default import.

  • To use any of the ex.LegacyDrawing.* implementations you must opt-in with the ex.Flags.useLegacyDrawing() note: new graphics do not work in this egacy mode

• Renames CollisionResolutionStrategy.Box collision resolution strategy to Arcade

• Renames CollisionResolutionStrategy.RigidBody collision resolution strategy to Realistic

• Collider is now a first class type and encapsulates what Shape used to be. Collider is no longer a member of the Body

• CollisionType and CollisionGroup are now a member of the Body component, the reasoning is they define how the simulated physics body will behave in simulation.

• Timer's no longer automatically start when added to a Scene, this Timer.start() must be called. (#1865)

• Timer.complete is now read-only to prevent odd bugs, use reset(), stop(), and start() to manipulate timers.

• Actor.actions.repeat() and Actor.actions.repeatForever() now require a handler that specifies the actions to repeat. This is more clear and helps prevent bugs like #1891

  const actor = new ex.Actor();
  
  actor.actions
    // Move up in a zig-zag by repeating 5 times
    .repeat((ctx) => {
      ctx.moveBy(10, 0, 10);
      ctx.moveBy(0, 10, 10);
    }, 5)
    .callMethod(() => {
      console.log('Done repeating!');
    });

• Removes Entity.components as a way to access, add, and remove components

• ex.Camera.z has been renamed to property ex.Camera.zoom which is the zoom factor

• ex.Camera.zoom(...) has been renamed to function ex.Camera.zoomOverTime()

• TileMap no longer needs registered SpriteSheets, Sprite's can be added directly to Cell's with addGraphic

  • The confusing TileSprite type is removed (Related to TileMap plugin updates excaliburjs/excalibur-tiled#4, excaliburjs/excalibur-tiled#23, excaliburjs/excalibur-tiled#108)

• Directly changing debug drawing by engine.isDebug = value has been replaced by engine.showDebug(value) and engine.toggleDebug() (#1655)

• UIActor Class instances need to be replaced to ScreenElement (This Class it's marked as Obsolete) (#1656)

• Switch to browser based promise, the Excalibur implementation ex.Promise is marked deprecated (#994)

• DisplayMode's have changed (#1733) & (#1928):

  • DisplayMode.FitContainer fits the screen to the available width/height in the canvas parent element, while maintaining aspect ratio and resolution
  • DisplayMode.FillContainer update the resolution and viewport dyanmically to fill the available space in the canvas parent element, DOES NOT preserve aspectRatio
  • DisplayMode.FitScreen fits the screen to the available browser window space, while maintaining aspect ratio and resolution
  • DisplayMode.FillScreen now does what DisplayMode.FullScreen used to do, the resolution and viewport dynamically adjust to fill the available space in the window, DOES NOT preserve aspectRatio (#1733)
  • DisplayMode.FullScreen is now removed, use Screen.goFullScreen().

• SpriteSheet now is immutable after creation to reduce chance of bugs if you modified a public field. The following properties are read-only: columns, rows, spWidth, spHeight, image, sprites and spacing.

• Engine.pointerScope now defaults to a more expected ex.Input.PointerScope.Canvas instead of ex.Input.PointerScope.Document which can cause frustrating bugs if building an HTML app with Excalibur

Added

• New property center to Screen to encapsulate screen center coordinates calculation considering zoom and device pixel ratio
• New ex.Shape.Capsule(width, height) helper for defining capsule colliders, these are useful for ramps or jagged floor colliders.
• New collision group constructor argument added to Actornew Actor({collisionGroup: collisionGroup})
• SpriteSheet.getSprite(x, y) can retrieve a sprite from the SpriteSheet by x and y coordinate. For example, getSprite(0, 0) returns the top left sprite in the sheet.
  • SpriteSheet's now have dimensionality with rows and columns optionally specified, if not there is always 1 row, and sprites.length columns
• new Actor({radius: 10}) can now take a radius parameter to help create circular actors
• The ExcaliburGraphicsContext now supports drawing debug text
• Entity may also now optionally have a name, this is useful for finding entities by name or when displaying in debug mode.
• New DebugSystem ECS system will show debug drawing output for things toggled on/off in the engine.debug section, this allows for a less cluttered debug experience.
  • Each debug section now has a configurable color.
• Turn on WebGL support with ex.Flags.useWebGL()
• Added new helpers to CollisionGroup to define groups that collide with specified groups CollisionGroup.collidesWith([groupA, groupB])
  • Combine groups with const groupAandB = CollisionGroup.combine([groupA, groupB])
  • Invert a group instance const everthingButGroupA = groupA.invert()
• Improved Collision Simulation
  • New ECS based CollisionSystem and MotionSystem
  • Rigid body's can now sleep for improved performance
  • Multiple contacts now supported which improves stability
  • Iterative solver for improved stability
• Added ColliderComponent to hold individual Collider implementations like Circle, Box, or CompositeCollider
  • Actor.collider.get() will get the current collider
  • Actor.collider.set(someCollider) allows you to set a specific collider
• New CompositeCollider type to combine multiple colliders together into one for an entity
  • Composite colliders flatten into their individual colliders in the collision system
  • Composite collider keeps it's internal colliders in a DynamicTree for fast .collide checks
• New TransformComponent to encapsulate Entity transform, that is to say position, rotation, and scale
• New MotionComponent to encapsulate Entity transform values changing over time like velocity and acceleration
• Added multi-line support to Text graphics (#1866)
• Added TileMap arbitrary graphics support with .addGraphic() (#1862)
• Added TileMap row and column accessors getRows() and getColumns() (#1859)
• Added the ability to store arbitrary data in TileMap cells with Cell.data.set('key', 'value') and Cell.data.get('key') (#1861)
• Actions moveTo(), moveBy(), easeTo(), scaleTo(), and scaleBy() now have vector overloads
• Animation.fromSpriteSheet will now log a warning if an index into the SpriteSheet is invalid (#1856)
• new ImageSource() will now log a warning if an image type isn't fully supported. (#1855)
• Timer.start() to explicitly start timers, and Timer.stop() to stop timers and "rewind" them.
• Timer.timeToNextAction will return the milliseconds until the next action callback
• Timer.timeElapsedTowardNextAction will return the milliseconds counted towards the next action callback
• BoundingBox now has a method for detecting zero dimensions in width or height `hasZeroDimen...

Excalibur v0.23.0

Thanks to @DavidLi119, @radist2s, @magnusandy, @djcsdy, and @ZuzuZain for their contributions!

Breaking Changes

• ex.Actor.scale, ex.Actor.sx/sy, ex.Actor.actions.scaleTo/scaleBy will not work as expected with new collider implementation, set width and height directly. These features will be completely removed in v0.24.0.

Added

• Add new collision group implementation (#1091, #862)
• New ex.Collider type which is the container for all collision related behavior and state. Actor is now extracted from collision.

• ex.Vector.scale now also works with vector input
• ex.BoundingBox.fromDimension(width: number, height: number) can generate a bounding box from a width and height
• ex.BoundingBox.translate(pos: Vector) will create a new bounding box shifted by pos
• ex.BoundingBox.scale(scale: Vector) will create a new bounding box scaled by scale
• Added isActor() and isCollider() type guards
• Added ex.CollisionShape.draw collision shapes can now be drawn, actor's will use these shapes if no other drawing is specified
• Added a getClosestLineBetween method to CollisionShape's for returning the closest line between 2 shapes (#1071)

Changed

• Change ex.Actor.within to use surface of object geometry instead of the center to make judgements (#1071)

• Changed moveBy, rotateBy, and scaleBy to operate relative to the current actor position at a speed, instead of moving to an absolute by a certain time.

• Changed event handlers in excalibur to expect non-null event objects, before hander: (event?: GameEvent) => void implied that event could be null. This change addresses (#1147) making strict null/function checks compatible with new typescript.

• Changed collision system to remove actor coupling, in addition ex.Collider is a new type that encapsulates all collision behavior. Use ex.Actor.body.collider to interact with collisions in Excalibur (#1119)
