v0.1.0

NEW FEATURES

This is the second major release of AthenaJS since initial release and contains lots of new features and numerous bugs were fixed.

Scene Debugger

AthenaJS 0.1.0 includes a new scene debugger which can be brought up by pressing d at any time:

With this you can easily inspect your scene objects and map tiles;

• view object hitboxes
• view tile behavior
• view tile number

To include it in your game, simply pass the debug:true option to your game's constructor.

New documentation!

The documentation has been rewritten from scratch using Docma.

It's now more pleasant to read with a section for each API group and a getting started section with tutorials.

New repository to quickly get started

A new repository has been created so that an AthenaJS project can be started in a minute or two: just clone the athenajs-webpack-starter repository, type npm install and you are ready to go!

New: Behavior class

• create and re-use your own object behaviors

New: Canvas class

• draw shapes using this new class: it's basically a wrapper over canvas drawing APIs

Deferred

• new Deferred.resolve() to create a resolved promise

Dom

• added ability to retrieve a dom node
• added limited support for changing css properties
• added Dom.find()to find children inside a collection
• added Dom.removeClass()
• Dom.addClass() can add several classes, separated by a space
• new keyword is now optional

Drawable (was: Object)

• new drawable.moveTo(): plan a move with custom easing function
• new drawable.setMask(): apply (rect for now) masks to your objects, including exclude mode
• drawable.move() renamed to drawable.update(), now receives current timestamp
• implemented opacity handling in drawable base class so that any drawable now supports opacity

Game

• added game.toggleFullscreen() to toggle game fullscreen support (requires the fullscreen API)
• new: pressing p key will call Game.scene.pause() and stop rendering & event loops
• new: if window becomes inactive, Game.scene.pause() is also called (requires visibility API)

InputManager

• gamepad detection and automatic mapping of arrow keys+ctrl+space to gamepad dpad + buttons 0/1
• new isKeyPressed() shortcut that can take string for common keys instead of keycodes (eg. isKeyPressed('UP'))
• InstallKeyCallback() can now accept multiple keys in a single call (separated by a space character)

Map

• new map.addTileSet(): quickly add a new set of tiles programmatically
• new map.updateTile(): update map tiles at runtime
• new map.getMaxDistanceToTile() for tiles-based platform moves
• new map.checkMatrixForCollision() for detecting collisions between tetris-like shapes & maps
• new map.shift() that allows to shift a part of the map (tetris-like games)
• new map.clear() that clears the whole map with tile/behavior (Tetris)
• new map.setEasing()to change scrolling easing function

ResourceManager

• now using new createImageBitmap API if available to allocate bitmaps in VRAM
• new ResourceManager.loadImage() no longer marked as private and can be used to load a single image

Scene

• new: Map doesn't need to be the same size as the scene anymore
• new: scene.loadImage()& scene.loadAudio()can be used in new scene.load()to preload sounds
• new scene.fadeIn(), scene.fadeOut(), Scene.fadeInOut()
• new scene.setLayerPriority()
• scene.setMap() now has new parameters: x, y that allow placing the map anywhere onto the scene

Sprite

• new sprite.addAnimations(): easily add new animations to your sprite at runtime

Athena-samples

• new: a new sample app has been written. It covers main topics: objects, effects, scene effects, behaviors, maps, sound

BUGS FIXED

Dom

• fixed: lots of fixes in jQuery-lite implementation

Game

• fixed: set target width/height (when no target is specified), fixes invisible background
• fixed: if a new scene was set before the previous one was finished loading, two scenes would end up being started

Map

• fixed: background & multidirectional scrolling
• fixed: triggers were not reset properly
• fixed: window calculation didn't work correctly if viewport window wasn't centered

Scene

• fixed: rewrote scene load/start code which is now more robust and allows adding objects before the scene has been loaded
• fixed: map.setBackgroundImage() didn't use scene target element
• added catch when calling scene.load(), this fixes silent errors because es6-promise was silently catching errors

Sprite

• fixed: angle/scale wasn't applied outside of animate, so calling mySprite.setAngle(Math.PI) would have not effect

SimpleText (was Text)

• fixed: undefined was displayed instead of empty string if no text was set

NEW APPS

• A new game has been developed using AthenaJS: athenatris

BREAKING CHANGES

Two classes have been renamed to avoid collisions with native JavaScript objects:

• GfxObject -> Drawable
• Text -> SimpleText
