0.8.0

Several important new features: raycasting, control over webgl shaders, a new system for wiring up inputs to entities, and more versatile graphics layers.

Only minor breaking changes in this release.

New features

  • The default WebGL shaders can now be overridden for existing components
  • Raycast collision checking is now supported
  • A full revamp of how graphics layers are implemented:
    • Multiple instances of the same layer type are supported
    • Static (UI) layers are supported, along with more general parallax effects
    • The z-order of rendering layers can be specified
  • A revamp of how "Multiway" and company are implemeneted:
    • A new "Control" system that maps specified user input to triggered event commands
    • A "Controllable" entity that makes it simple to bind to these events
  • Text can now be dynamically generated each frame for the "Text" component
  • Better control over text alignment on Canvas
  • Changing the timer steptype now fires an event
  • Graphics layers created using Crafty.s
  • Pause supported by particle and delay components
  • Easier to specify animations when the sprite spans multiple rows
  • "Jumper" component can now be triggered directly

Breaking changes

  • All drawing-related methods of the "2D" component moved to a new "Renderable" component. (This should only affect custom draw code -- WebGL/Canvas/DOM components automatically require "Renderable".)
  • "Multiway" and company have a different implementation with slightly different behavior in some corner cases. Triggering keyboard events directly on these entities will no longer work -- instead, trigger the related control events.
  • If you were previously setting text-align via CSS, you might need to switch to explicitly calling the new textAlign method.

Bug fixes

  • WebGL entities unregistered correctly
  • Fixes to "Gravity" component
  • Fixed issue where audio could continue repeating when only 1 play is specified

Project

  • Open sauce tests
  • Updated node packages; switch to yarn over npm
  • Numerous documentation fixes

Commits since the last version.

0.7.1

A minor update with a few fixes.

  • Including Crafty cross-domain should no longer throw an uncaught exception when checking localStorage
  • Bug unregistering WebGL entities for some component types, causing the max entities limit to be reached too quickly
  • Fixes to the release process to ensure that bower release functions correctly

commits

0.7.0

Contains a lot of new functionality and bug fixes.

Highlights

  • WebGL support for Image, Sprite, and Color. (Simply switch from Canvas or DOM to WebGL -- rendering exactly matches the other backends.)
  • A new motion system with more flexibility.
  • Shortcuts for common operations

Breaking changes

  • Motion components now take speeds in px/second instead of px/frame. (Conversion)
  • You may notice slight differences in jump / gravity behavior even after conversion. (see #905).
  • Polygons are declared using the syntax [x0,y0,x1,y1..] instead of [[x0,y0],[x1,y1]..]
  • Changes to the diamondIso api
  • Crafty.DOM and Crafty.Canvas renamed to Crafty.domLayer and Crafty.canvasLayer respectively

Full change list

New core features

  • Two common init operations were given shortcuts when defining a component:
    • The events property lets you specify a set of event handlers directly
    • The required property lets you specify a list of components to add
  • Animated properties (both "Tween" and viewport functions) now support a variety of easing types
  • Support for multitouch events (has to be explicitly enabled)
  • Objects can now be declared as a system using Crafty.s(). This gives them init and event methods much like entities.
  • Support for WebGL as a rendering layer
  • New MouseWheel event that triggers globally like a keyboard event

Node support

  • Explicitly headless builds are now possible
  • Local storage support for node

2D functionality

  • pos and mbr functions now accept an optional object to assign the x/y/w/h properties to, instead of always creating a new one
  • Fix a bug in the SAT algorithm that could report collision depth incorrectly in some circumstances
  • Optimize polygon to use a flat array, instead of an array of points.
  • Crafty.polygon now has a clone() method if you want to reuse the same polygon in multiple components.
  • Revamp of the diamonIso functionality

Better motion components

There are several new components that handle moving objects, and existing components like TwoWay and Gravity were refactored to use them

  • "Motion": for handling two dimensional motion -- allows you to set acceleration and velocity
  • "AngularMotion": For handling rotation
  • "Supportable": For handling platform behavior
  • Multiway and friends now use Motion internally, and so work properly with Crafty's timer step types.
  • TwoWay now uses Supportable.

Bug fixes

  • Switching Sprite components sometimes failed to update the image when using DOM components
  • The Canvas context was mismanaged when entities were both rotated and flipped
  • Mobile positioning was handled weirdly, resulting in both layout and touch event bugs
  • Various bugs with disableControls
  • Numerous small issues with documentation
  • Problems with event cancelling
  • Fixed a long standing issue where DOM sprites blinked and flickered in Chrome
  • Numerous bug fixes related to calling Crafty.stop().
  • A use of constructor.name which broke IE9
  • viewport.follow interacted badly with viewport.scale
  • explicitly declared viewport.bounds incorrectly mutated when viewport.scale was called with clamp-to-entities enabled.
  • Declaring events and then removing them had a performance impact

Internal Improvements

  • Source files are now logically organzied into directories, and many monolithic files were broken into smaller units
  • Graphics layers are now more loosely coupled to core, preparing the way for arbitrary layers
  • Refactored event handling to be more consistent
  • Each commit into develop triggers an automatic build on Travis which is uploaded to the Crafty-Distro repo.
  • Simpler scripts for generating documentation data as a json file
