Particle.Emitter.explode (or `Emitter.start` with the `explode` parameter set to `true`) will immediately emit the required quantity of particles and not delay until the next frame to do so. This means you can re-use a single emitter across multiple places in your game that require explode-style emissions, just by adjusting the `emitter.x` and `emitter.y` properties before calling explode (thanks Insanehero)
Cache.autoResolveURL is a new boolean (default `false`) that automatically builds a cached map of all loaded assets vs. their absolute URLs, for use with Cache.getURL and Cache.checkURL. Note that in 2.1.3 and earlier this was enabled by default, but has since been moved behind this property which needs to be set to `true` *before* you load any assets to enable.
Cache._resolveUrl has been renamed to Cache._resolveURL internally and gained a new parameter. This method is a private internal one.
Cache.getUrl is deprecated. The same method is now available as Cache.getURL.
XML files weren't being added to the URL map.
Cache._resolveURL was causing a Sound double-load in Firefox and causing errors (thanks @domonyiv #1253)
- The `disabled` property of various input classes has been inverted to `enabled`.
Direct/internal usage of `disabled` has been transformed to `!enabled`.
- A `disabled` get/set property has been added to wrap `enabled`, and marked as @deprecated
This ensures current API compatibility.
TilemapLayer
- Added "delta scroll rendering"
- Enabled (by default) via `renderSettings.enableScrollDelta`
- Dramatic CPU reduction: 30% to 2% scrolling 50x37 region
- Side-effect: fixed some Chrome de-opt issues with `render`
- Various rendering updates and removal of many `_mc` field
- Made `index` a read-only propert that reflects the layer.index
- Creates a local cache from tile index -> tileset, added `resetTilesetCache`
- Also prevents crash when an index not associated with a tileset is
used; see `missingImageOverfill`.
- Various debug options moved to `debugSettings` and simplified; documentation updated.
- Uses `debugSettings.missingImageOverfill` and `tileColor` (deprecated) to display invalid tileset images
- Only change the context alpha when the tile alpha changes; in Chrome 38
this removed a .5% penalty
- Added `renderSettings` which controls misc. rendering/optimizations.
- Updated documentation to @member, clarified
Tileset
- Added `containsTileIndex` method to allow being queried if the specific tile index is handled/supported.
- Uses a firstgid bias and interlacing to fit the data in single densely packed array.
- Updated documentation to @member, clarified
