## v1.1.0 (2018-02-05)

### Breaking change: matter.js is split from dxopal.js

To use `DXOpal::Sprite::Physics`, you need to load matter.js explicitly.

Old:
    
    <script src="dxopal.min.js"></script>

New:

    <script src="matter.js"></script>
    <script src="dxopal.min.js"></script>

### Other improvements:

- new: Image#set_color_key
- new: Window.draw_scale
- new: Show the message of an exception if there is a `<div id='dxopal-errors'>`
- new: Add --port to dxopal command
- fix: shot/hit method names for Sprite.check are now customizable
- fix: Multiple loops runs when Window.loop is called more than once
- internal: Upgrade to Opal 0.11.0

### Breaking Change: resource loading

Image.load and Sound.new are removed. They look like a synchronous API
but actually were not. It was fun to emulate DXRuby APIs with JS Promise,
but I found it 
very confusing while implementing the AppleCatcher example.

Since v0.2, resource loading look like this.

```rb
Image.register(:player, 'images/player.png')
Sound.register(:game_over, 'sounds/game_over.wav')

Window.load_resources do
  Window.loop do
    # ... Window.draw(0, 0, Image[:player]) ...
    
    # ... Sound[:game_over].play ...
  end
end
```

- new: Window.draw_box_fill
- new: Sprite.update, Sprite.clean

- fix: Vanished sprites have no collision
- new: Image#slice

## v0.1.0 (2017-04-24)

- new: Sprite.new, collision detection
- new: Input.mouse_pos_x, mouse_pos_y

## v0.0.3 (2017-04-23)

- fix: Input.key_down? return true after key is released
- new: color constants
