Despite this, support of all properties is only at 77%, with 229 tasks being implemented out of 294. ActionScript 1.0 and 2.0/AVM1 - 95% of the language and 73% of the API are supported.Today, it is one of the most prominent alternative Flash players. It has become notable since Flash's discontinuation was announced and Flash support in web browsers weakened. It was later renamed to Ruffle, and became a reimplementation of Flash Player. There's also some security-related and custom socket classes which expose the movie's origin, which is validated by some domain locks.ĥ.Mike Welsh began development of a project called Fluster in 2016. Remaining AS2 classes - Someone PR'd BitmapData support but it's incomplete. Video decoding - I have an h263 decoder written but still need to tie it into the stage, and it'll probably be super-inefficient on web unless I port decoding over to GPU shadersĤ. Core AS3 data types (String, Number, int, uint, Vector., Point, Transform, JSON, etc) - I'll do this as-needed for other AS3 work or specific games that depend on these methodsģ. Core AS3 display object support - I'm working on this with somewhat-slow progressĢ. Ideally, we'd like to have some kind of low-level Flash-like vector drawing implementation, but that would be a significant performance loss unless we could either parallelize it or somehow convince a GPU to do it.įurthermore, a lot of that is going to have to come after all the compatibility and implementation work we still need to do. We are using GPUs to render polygonalized shapes where available, though that has some accuracy issues with stroke scaling. (Ruffle is all people working spare-time currently) The performance ceiling with Rust is way higher than JavaScript, but we're nowhere near that yet, much yet at the point where we'd have to start writing JIT compilers for AS2 or AS3.

Shumway used to be a Mozilla project with corporate backing that would explain why their implementation was so complete.

For example, after figuring out how DisplayObjectContainer IDs and timeline depths interact, Toad06 and I went through several rounds of regression testing with AVM1 content because of how foundational the changes were. Adding AS3 support also means making sure we can leverage the same object hierarchy without breaking any of those fixes. Most of our effort has gone into finding and implementing the bottomless pit of strangeness that is AVM1 and it's execution model. DisplayObjectContainer support just landed a few days ago, but yes, our AS3 support is basically nothing right now.
